Question 1

Clegg et al. Applied Animal Behavior Science. 2008.

What was the study design?

Answer 1

Data were gathered on the behavioural and physiological characteristics of five cribbers, six weavers and six non-stereotypic (control) mature Thoroughbred geldings for a period of 16 weeks. The horses were hired from their owners and stabled individually throughout the trial. Cribbers and weavers had been known to stereotype for at least 12 months prior to commencement of the study. Behavioural data were collected using video surveillance.

Question 2

Clegg et al. Applied Animal Behavior Science. 2008.

At what times did cribbers stereotype most frequently? What about weavers?

Answer 2

Cribbers stereotyped most frequently (P < 0.001) in the period 2–8 h following delivery of concentrated food, reinforcing the suggestion that diet is implicated in cribbing behaviour. Weavers stereotyped most frequently (P < 0.001) during periods of high environmental activity such as during routine pre-feeding activities and in the hour prior to daily turnout, presumably when anticipation and stimulation were at their highest levels.

Question 3

Clegg et al. Applied Animal Behavior Science. 2008.

Did cribbers and weavers take more or less time to consume their feed compared to control horses?

Answer 3

Cribbers and weavers took longer than control horses to fully consume their ration, suggesting possible differences in motivation to feed, distress levels, satiety mechanisms or abdominal discomfort.

Question 4

Clegg et al. Applied Animal Behavior Science. 2008.
How did oro-caecal transit time, digestibility, plasma cortisol concentration and heart rate vary between the cribbing/weaving horses and the control horses?

Answer 4

Physiological data were collected throughout the trial and there were no differences in oro-caecal transit time, digestibility, plasma cortisol concentration or heart rate among the three behavioural groups.

Question 5

Clegg et al. Applied Animal Behavior Science. 2008. How do they define stereotypies?

Answer 5

Relatively invariant behaviour patterns with no apparent function.

Question 6

Clegg et al. Applied Animal Behavior Science. 2008.
What percentage of stabled horses display stereotypies?

These authors reference Nicol. 1999. Proceedings of the BEVA Specialist Days on Behaviour and Nutrition.

Answer 6

Oral and locomotory stereotypies are common among
intensively managed horses, being reported in approximately 4% and 3% of the adult horse
population, respectively.

Question 7

Clegg et al. Applied Animal Behavior Science. 2008. Numerous management techniques have been blamed for the development of stereotypies
in horses. Which are discussed in this paper?

Answer 7

These include confinement, isolation from other horses, provision of small concentrated feeds and both a lack of stimulation and
an over-abundance of environmental activity.

Question 8

Clegg et al. Applied Animal Behavior Science. 2008.
The horses in this study were stabled for the average number of hours per day of stabled race horses. How long is that?

These authors reference McGreevy. 1994. Equine Behavior: A Guide for Veterinarians and Equine Scientists.

Answer 8

Horses spent 22 h per day in their stables, in accordance with usual confinement of a stabled race horse
(McGreevy, 2004).

Question 9

Clegg et al. Applied Animal Behavior Science. 2008.

How many times per day did cribbers crib?

Answer 9

Cribbers were observed to crib-bite 147.0 +/-33.1 times per daily period of observation. Since
horses were each only observed for 10% of the 22 h that they were in the stables each day
(132 min of observation per day in total), the actual cribbing frequency is likely to have been
approximately 1470 events per horse per day, assuming behaviour was evenly distributed
throughout each 5 min block.

Question 10

Clegg et al. Applied Animal Behavior Science. 2008.

How many times per day did weavers weave?

Answer 10

Weavers were observed to weave 53.0 +/- 12.4 times per daily period of observation, equating to a daily weaving frequency of approximately 530 events per
horse.

Question 11

Clegg et al. Applied Animal Behavior Science. 2008.
It is common to hear in the riding community that horses learn stereotypies through mimicry. Is this idea supported by the findings of this study?

Answer 11

No. No stereotypic behaviour was observed in any of the control horses in this study, despite visual
contact with stereotypic horses. This short-term finding supports the research of Marsden (1995)
and McGreevy (1999), which also suggest that horses do not learn these behaviours by mimicry.

Question 12

Clegg et al. Applied Animal Behavior Science. 2008.

Do the authors believe that cribbing in their study can be explained by gastric pain?

Answer 12

Maybe. The finding that cribbers stereotype most frequently during and particularly following
consumption of meals supports the results of other researchers (Kennedy et al., 1993; Gillham
et al., 1994; McGreevy et al., 1995; McGreevy and Nicol, 1998a; Cooper et al., 2005). However,
the peak cribbing frequency in the current study began 2–4 h post-feeding and reached its highest
point 6–8 h post-feeding, which is a longer time-frame than previously reported. This suggests
that gastric pain was not the sole source of any visceral discomfort that cribbers underwent in the
current study. If cribbing is indeed a response to visceral discomfort, it appears more probable
from the current data, that it is related to fermentative acidosis in the hindgut, since the
commencement of the period of maximal post-feeding cribbing (between 2 and 8 h post-feeding)
coincided temporally with the initial arrival of ingesta in the caecum (approximately 110 min
post-feeding). That said, it is also possible
that there is a cumulative effect of concentrated food reaching the inflamed gastric lining,
resulting in greater discomfort as the horse continues to eat for up to 9 h after delivery of the
ration.

Question 13

Clegg et al. Applied Animal Behavior Science. 2008.

Do the authors report that cribbing increases or decreases oro-caecal transit time?

Answer 13

Cribbers tended to have a shorter oro-caecal transit time than control horses. This differs from
the findings of McGreevy and Nicol (1998b), who have suggested that cribbing may help to
shorten oro-caecal transit time in horses that would otherwise have a slow rate of passage through
the foregut, resulting in a decrease in their oro-caecal transit time to within a normal range. In the
current study, it is possible that cribbing may have shortened oro-caecal transit time even more
than has been reported previously

Question 14

Clegg et al. Applied Animal Behavior Science. 2008.
DO the findings of this study support the idea that cribbing occurs as a result of a horses unmet need to forage (motivation to display foraging behavior when no feed is available)?

Answer 14

No. The theory that cribbing occurs in stabled horses as a result of a behavioural need to
feed is questioned by this research, particularly as cribbing occurred while feed was still
available.

Question 15

Answer 19

Only referred to matrilineal relationships b/c paternity was unknown for these cats

Question 20

Curtis, Knowles, Crowell-Davis 2003. AJVR.

The number of times a cat was within 1 meter of a focal cat (the individual cat who was being observed by the researchers) and allogroomed by a given cat was significantly associated with what?

Answer 20

Being a relative and familiarity between cats (ie, how long they had lived together)

Question 21

Curtis, Knowles, Crowell-Davis 2003. AJVR.

What was the difference between cats with relatives who were present in the colony for 7 months and cats with relatives who were present in the colony for 76 months?

Answer 21

of times relative was within 1 m and mean # of times nonrelative cat was within 1 m of focal cat was lower for cats who knew each other for 7 months vs cats who knew each other 76 months

Question 22

Curtis, Knowles, Crowell-Davis 2003. AJVR.

What was the difference in the # of times a cat was within 1 m of the focal cat and # of times a cat was groomed by the focal cat between relative cats vs relative equivalent cats?

Answer 22

Relative cats were more likely to be within 1 m than relative equivalents; relatives were groomed significantly more likely than relative equivalents

They were all from groups in which the mother was present in the colony

Question 25

Curtis, Knowles, Crowell-Davis 2003. AJVR. What were the main findings of this study?

Answer 25

1. Allogrooming serves social function to establish and maintain affiliative relationships. Not just hygienic function. 2. Cats in this colony preferentially remained near and allogroomed their relatives and cats with who they were more familiar more than nonrelatives and cats with who they were less familiar. 3. Longer unrelated cats live together, the more they groom each other and spend time together.

Question 26

Curtis, Knowles, Crowell-Davis 2003. AJVR. What relationship did Barry and Crowell-Davis find between the length of time cats cohabitated and rate of aggression?

Answer 26

Inverse. Longer unrelated cats live together, the less aggression.

Question 27

Curtis, Knowles, Crowell-Davis 2003. AJVR. What was a limitation in this study regarding the contact between cats prior to the study?

Answer 27

The cats with relatives spent time with their relatives during socialization prior to introduction to the colony. No nonrelatives were kept together during this period. Strong social bonding with these cats may have occurred if there had been contact.

Question 88

Dodman et al. Am J Vet Res. 1987. | What side effects were seen with the nalmefene CRI treatment horses.

Answer 88

Doses of nalmefene as large as 0.4 mg/kg, IV, produced only minor side effects. These side effects included yawning, some passage of semifluid fecal material, intermittent penile relaxation, and mild sedation. Treated horses responded normally to external stimuli, retained their appetites, and performed appropriately when ridden. Sedation wore off during the course of prolonged infusions.

Question 89

Gillham/Dodman 1994. The effect of diet on cribbing behavior and plasma B-endorphin in horses. AABS. To what did the authors attribute the increase in cribbing rate following the two grain-based diets?

Answer 92

Decreasing amount of grain fed to cribbing horses may reduce rate of cribbing and other stereotypies Equine self-mutilation syndrome has been reduced in some horses fed reduced grain (McClure 1992) Diet based on high quality hay (alfalfa) rations may reduce cribbing by minimizing central opioid release

Question 93

Dodman et al. Am J Vet Res. 1987. | Cribbing is thought to cause to activation of which receptor in the CNS?

Answer 93

Narcotic and dopamine receptors

Question 94

Intravenous or IM injections of narcotic antagonists decreased these rates to almost zero by about 20 minutes after the injection was given.

Question 96

Dodman et al. Am J Vet Res. 1987. | Which narcotic antagonists were used and how long about did the effects of narcotic antagonist injections last?

Answer 96

Effective doses were 0.02 to 0.04 mg of naloxone/kg, 0.04 mg of naltrexone/kg, 0.08 mg of nalmefene/kg, and 0.02 to 0.03 mg of diprenorphine/kg. The duration of the response to a single injection ranged from 20 minutes for naloxone to 4 hours or more for nalmefene and diprenorphine.

Question 97

Dodman et al. Am J Vet Res. 1987. | This study also used CRIs of a narcotic antagonist to treat cribbing. Which drug was this and were the CRIs effective?

Answer 97

Crib-biting could be prevented completely for up to a week by continuous infusion of 5 to 10 mg of nalmefene/hr. Crib-biting resumed when the infusion was discontinued, and plasma nalmefene concentrations decreased to below 5 ng/ml.

Question 98

Dodman et al. Am J Vet Res. 1987. | What side effects were seen with the nalmefene CRI treatment horses.

Answer 98

Doses of nalmefene as large as 0.4 mg/kg, IV, produced only minor side effects. These side effects included some passage of semifluid fecal material, intermittent penile relaxation, and mild sedation. Treated horses responded normally to external stimuli, retained their appetites, and performed appropriately when ridden. Sedation wore off during the course of prolonged infusions.

Question 99

Dodman et al. Am J Vet Res. 1987. | Does this study suggest that we should use narcotic antagonists to treat stereotypic behavior disorders?

Boredom, frustration, stress, heredity, mimicry, diet

Question 102

Dodman et al. Am J Vet Res. 1987. | What diseases may cribbing make a horse more predisposed to?

Answer 102

Incisor wear and colic due to aerophagia

Question 103

Dodman et al. Am J Vet Res. 1987. | Why are opioid antagonists thought to be helpful for reducing stereotypies (proposed mechanism of action)?

Answer 103

Stereotypic behaviors are thought to be mediated by dopaminergic pathways in many species. Stress is thought to cause overproduction of endogenous opioids which can change sensitivity of dopamine receptors in the CNS. This is how stress is thought to encourage stereotypy. We can counter these efects with opioid antagonists. Stress, apomorphine and amphetamines may also enhance stereotypic behaviours directly through dopamine release.

Question 104

Dodman et al. Am J Vet Res. 1987. | Why don't we use dopamine blocking medications to treat stereotypy in horses?

Answer 104

Dopamine blocking agents like haloperidol also inhibit stereotypic patterns. Dopamine blocking agents theoretically would work in horses but they are not used in ridden horses because the sedation makes them unsafe to ride.

Question 121

Guy et al. Risk factors for dog bites to owners in a general veterinary caseload. 2001. What type of study was this?

Answer 121

Detailed telephone survey of dog owners from a cross-sectional population of veterinary clientele in the Canadian provinces of New Brunswick, Nova Scotia, and Prince Edward Island. Interviews were successfully completed with 515 of 640 individuals selected from a study population of 3226 dogs by a formal random process. 227 biting and 126 non-biting dogs were included for analysis of risk factors. All dogs were at least 6 months of age. Play mouthing was excluded.

Question 122

Guy et al. Risk factors for dog bites to owners in a general veterinary caseload. 2001. How did the mean weight and mean age differe between the biting and non-biting groups?

Both the mean weight and age of biting dogs were significantly lower than that of non-biting dogs.

Question 123

Guy et al. Risk factors for dog bites to owners in a general veterinary caseload. 2001. What risk factors were associated with biting?

Answer 123

Significant risk factors for an outcome of biting were: the dog being female (particularly if small dog), the presence of one or more teenage children in the home, a history of a pruritic or malodorous skin disorder which had received veterinary treatment, aggression over food in the first 2 months of ownership, the dog having slept on someone's bed in the first 2 months of ownership (only for little dogs), playing tug (only for bigger dogs - accidental bites are included) and the dog having been given a significantly higher ranking for excitability based on its behaviour in the first 2 months of ownership.

Question 137

Hart. 1973. Effects of castration on fighting, roaming, and urine spraying in adult male cats. JAVMA. What was the effect of neutering?

Answer 137

Owners reported a rapid post op decline of fighting, roaming and urine spraying in 53, 56 and 78% of cats respectively. Owners reported a gradual post op decline of fighting, roaming and urine spraying in 35, 38 and 9% of cats respectively. Improvement does not mean complete elimination - may still happen infrequently.

Question 138

Hart. 1973. Effects of castration on fighting, roaming, and urine spraying in adult male cats. JAVMA. All cats had been neutered during adulthood in this survey based study. Did age of castration affect post op decline of fighting, roaming, or urine spraying?

Question 141

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What was the objective of the study and the study design?

Answer 141

Objective: To investigate the behaviors expressed by puppies when exposed to 3 different contexts in a vet clinic environment. Study design: Puppies between 8-16 weeks, adopted 1 week prior to evaluation. The tech would take the dog to the back immediately in an effort to standardize as much as possible. There were 3 parts to each assessment: free floor evaluation, PE on table, and manipulation of the puppy on the floor.

Question 142

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior The Scott and Fuller, 1965 paper cited in this study suggested that the puppy socialization period is when?

Answer 142

3-12 weeks of age. During this time, social contact and behavior modification is easier, which is critical for normal puppy development.

Question 143

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior The Seksel et.al study referenced in this paper suggested what with regard to a puppy’s response to novel and social stimuli?

Answer 143

Suggested that a puppy’s first response to novel and social stimuli appears to be an indicator of its subsequent response.

Question 144

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What did the Free Floor (FF) evaluation consist of?

Answer 144

The pup was on the floor for 2 minutes, while the vet was in the room filming but not interacting with the dog. The same room was used each time.

Question 145

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What did the physical exam consist of (PET)? Was this part standardized?

Answer 145

The dog was examined on a stainless steel table. The PE itself was standardized - included eye, mouth, and ear exams, palpación of the LN, chest, and abdomen. They also examined the paws, toes, and locomotor system. Finally, the HR and temp were recorded. The duration varied pending on compliance.

Question 146

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What did manipulation of the pup on the floor (MF) consist of? Was this standardized?

Answer 146

Occurred after the PET. The vet called the pup and asked it to sit. They were approached if the pup did not come voluntarily. Manipulation - gentle exam of the pup’s ears, head, limbs, and toes. The dog was then restrained for 5 sec by the shoulders, then by the hips for another 5 sec. Finally, the leash was attached and the dog got a treat. The duration of this section depended on compliance.

Question 147

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What behavioral categories were considered?

Answer 147

For FF - 6 different behavioral categories: activity, exploration, facial expression, interaction with the vet, vocalization, and other behaviors. For PET and MF: the nature of the interaction with the vet along with facial expressions and ear position.

Question 148

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What were the results of the FF portion of this study?

Answer 148

Pups were active and oriented to the environment - high locomotion and exploration. Most pups were silent, didn’t pant, and interacted little with the vet. Whining was the principal type of vocalization in those pups that were vocal. Male pups were more gentle than females and the odds of them scratching was higher in males.

Question 149

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What were the results of the PET portion of this study?

Answer 149

Most pups didn’t pant extensively, they usually kept their ears in a normal position, and showed passive behavior. 63 licked their lips 19 yawned 1+ times

Question 150

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What were the results for the MF portion of this study?

Answer 150

Wide range in each behavior during this section of the floor. Compared to PET, they panted more and were less passive on the floor. Ears were usually normal, though there was more pronounced variation when compared to PET. Fewer dogs licked their lips (14) and yawned (5) and the frequency of these behaviors was also lower when compared to the table. Female pups were more passive than males and they held their ears back less than males.

Question 151

Godbout, Palestrini et.al, 2007. Puppy Behavior in the veterinary clinic: A pilot study Journal of Veterinary Behavior What were the differences in behaviors between the PET and MF parts of this study?

Answer 151

More puppies panted and were less passive during the MF portion of the study. However, those that panted and were less passive exhibited similar behaviors both in the PET portion and FF portion. It is also important to note that the MF portion of this study was at the end, which could have led to a decrease in tolerance by this portion of this study.

Question 174

Houpt. 2002. Formation and dissolution of the mare-foal bond. Applied Animal Behaviour Science. In what situations did they record behaviors of the mares and foals?

Answer 174

The behavior of mares at foaling (up to 60 min after) and their behavior during subsequent weekly brief separations from their foals was quantified.

Question 175

Houpt. 2002. Formation and dissolution of the mare-foal bond. Applied Animal Behaviour Science. What behavior did the mares show in the first 30 minutes after foaling?

Answer 175

Thirteen multiparous pony mares were observed for the first 30 min after foaling. Activities directed toward the foal and toward the fetal membranes were recorded. There were 16 +/- 8 contacts with the fetal membranes, most in the first 10 min post-partum. There were 81 +/- 12 activities (licking, touching and sniffing) directed toward the foal with licking being the most common. There was a downward trend in foal contacts over the first 30 min.

Question 176

Houpt. 2002. Formation and dissolution of the mare-foal bond. Applied Animal Behaviour Science. What behaviors did the mare show in the 30-60 minute period after foaling?

Only one of the foals suckled in the first 30 min, but half had suckled by 60 min. Did not record beyond 60 min.

Question 178

Houpt. 2002. Formation and dissolution of the mare-foal bond. Applied Animal Behaviour Science. During separation periods, how did mare and foal contact seeking behavior change over time?

Answer 178

Ten mares and foals were separated for 5 min each week for 9 weeks. Mare and foals' contact seeking responses increased from weeks 1 to 2 and then decreased with foal age. This indicates that foal attachment to the mare is not complete until it is 2 weeks old. They should be minimally disturbed during this time.

Question 179

When does Houpt believe based on this study was the most stressful time for weaning?

Answer 179

2 weeks. Why? After 2 weeks contact seeking behavior of both mare and foal starts to decline but they increase over the first 2 weeks.

Question 206

Mertens et al. 2006. The Effects of Clomipramine Hydrochloride in Cats With Psychogenic Alopecia: A Prospective Study. J Am Anim Hosp Assoc. What was the basic study design?

Answer 206

A double-blind, placebo-controlled clinical trial was conducted to determine the efficacy of clomipramine hydrochloride in cats with psychogenic alopecia. Twenty-five cats were randomly assigned to receive clomipramine hydrochloride (0.5 mg/kg orally q 24 hours) or placebo for 56 days. Eleven cats in each group completed the trial.

Question 207

Mertens et al. 2006. The Effects of Clomipramine Hydrochloride in Cats With Psychogenic Alopecia: A Prospective Study. J Am Anim Hosp Assoc. What therapeutic effect was seen?

Answer 207

None. The results of this study showed that clomipramine hydrochloride failed to demonstrate significant changes in the number of grooming bouts, hair regrowth, and the area of alopecia in cats with psychogenic alopecia when compared to a placebo. It was uncertain whether these results reflected a lack of drug efficacy, insufficient treatment duration, or an insufficient number of cases enrolled. >50% of the owners of cats that received clomipramine felt that their pets improved by at least 50%. In contrast, this level of improvement was noticed by <33% of owners of cats treated with the placebo. This was not statistically significant.

Question 213

Malamed 2010: Logistic regression was used to control for confounding introduced by matching on time of case occurrence. Is this a parametric or non-parametric test?

Answer 213

The logistic regression model is parametric because it has a finite set of parameters. Specifically, the parameters are the regression coefficients. These usually correspond to one for each predictor plus a constant.

Question 214

Malamed 2010: Why could this study not be used to replicate previous results (Archer et al. 2004)) that Epiploic foramen entrapment colic is more likely with horses with stereotypes?

Answer 214

Small n of n=4

Question 215

Malamed 2010: Significant results?

Answer 215

1. Horses that had a history of cribbing or windsucking were more likely to have had colic than those that did not crib (OR = 2.19, p = 0.032) - but was unassociated with 1 category or severity of colic over another. 2. 42% (93/219) of horses with colic had experienced an environmental change in the week prior to the episode (OR = 3.93, P<0.001)

Question 216

Malamed 2010: Why might this be a seminal study?

Answer 216

this was the first large scale case-control study to evaluate cribbing/windsucking and temperament as risk factors for different types of colic.

Question 217

Malamed 2010: What was the prevalence of cribbing/windsucking in the control group? - Prevalence in the colic group? - What was the prevalence reported by Albright 2009?

Answer 217

6.8% 11% 4.4%
