Q

Travelling by air

A

Most airlines dont allow animals to travel with their owners in the cabin, instead they travel in a heated and pressurised area of the hold.

The International Air Transport Association Standards require their container to be large enough to stand up in and turn around with ease and have strict regulations.

Clients should be advised to contact DEFRA for info regarding entry requirements to their destination.

Travelling can be an issue for reptiles due to their inability to regulate body temp. Expert Reptile shipping experts should be used.

Q

Renal disease

A

-chronic renal failure (CRF)
-progressive disease
-common in senior cats
-damage is irreversible
-clinical signs : show when up to 75% of kidney function is lost
-loss of function is associated with the accumulation of toxic protein catabolites and the failure to excrete phosphorus

178
Q

Dietary management for renal disease

A

-restricted protein to reduce nitrogenous waste
-highly digestible and high biological value protein
-renal diets - specially formulated to prevent protein malnutrition
-restrict phosphorus (phosphorus binders)
-Control sodium and chloride
-potassium supplements
-enhanced B-complex vitamins
-omega 3 fatty acids
-palatabiltiy

179
Q

Hepatic disease

A

Liver functions may be affected
The liver can regenerate and nutritional support can support the liver to delay or prevent irreversible damage

Diet must have:
Moderate levels of high quality protein
High L-carnitine and L-arginine
Appropriate levels of zinc and low copper
Reduces liver workload and helps to regenerate
Moderate to high fat levels increase energy density and reduces protein catabolism
Added vitamins help avoid nutrient deficiencies commonly related to liver issues

Copper toxicity can occur in westies, terriers and Doberman. Results in copper accumulation in the liver
Feed a diet low in copper and high in zinc as zinc reduces intestinal uptake of copper

180

Diet management will depend on which crystals are present
Increased water intake and wet diet

194
Q

Struvite and calcium oxide

A

More common in cats but can occur in dogs
Diets acidify urine which helps to dissolve crystals/stones
Diluting urine decreases the urinary concentration of struvite and calcium oxalate crystals
Greater urinary volumes helps to flush the bladder out

Diets are low in magnesium

195
Q

Urate and cystine

A

Mainly affects dogs
Needs to be surgically removed if large
Diet alkalises the urine helping the stones to dissolve

Phenotype = genotype + environment

224
Q

What are lethal genes?

A

Incompatible with life, if an animal expresses a lethal gene it will die from the effects sooner or later.
Usually recessive genes so the affected individual must be homozygous

225

226
Q

Define delayed lethal

A

Affected individuals will die from a progressive condition later in life

These produce mild abnormalities that may not necessarily kill the animal

228
Q

Mutations

A

Random chance mutation = genetic change
Chemical change or damage = radiation
These changes pass onto the next generation
If the mutation is harmful and kills the individual the gene will die out and not be passed on
May produce an advantage and that would be passed onto the next generation though reproduction

Q

Mendels 1st law of inheritance

A

Each person has 2 genes that determine every characteristic.
Mother has 2 genes for eye colour and father has 2 genes for eye colour
But you only get 1 from each
The law of segregation says that the one you get from each parent is random

232
Q

Mendels 2nd law of inheritance
Independent assortment

A

The law of independent assortment
Refers to the fact that any plant or animal contains many kinds of genes
1 gene determines flower colour, 1 gene determines stem length and 1 determines the shape of the pod
Mendel discovered that the way alleles from different genes separate and then recombine is unconnected to other genes.
That is reliant on a plant containing genes for colour (RR) and for the shape of pod (TT) then Mendels 2nd law says that 2 genes will segregate independently

233
Q

Mendels 3rd law
Law of dominance

A

Some alleles of the same gene are dominant and others recessive.
An organism only needs 1 copy of the dominant allele to display the effect of that allele.

237
Q

Luteinizing hormone (LH)

A

Produced by the anterior pituitary

Targets the leydig cells in males and stimulates the release of testosterone

In females it targets the ovaries causing ovulation and development of the corpus luteum.

238
Q

Follicle stimulating hormone (FSH)

A

Produced by the anterior pituitary

Targets the Sertoli cells in males causing spermatogenesis

In females it targets the ovaries, stimulating growth of the follicles which contain the ova

Neonatal kittens and puppies

A

-unable to stand at birth but can crawl
-stand from 10 days
-walk at 3 weeks
-born with eyes closed,usually open around 10-14 days
-cornea appears cloudy until 4 weeks
-kittens can be born with strabismus (can persist until around 8 weeks of age )
-dam simulates perineal region for the first 2-3 weeks to allow defecation and urination

301
Q

When animals are born

A

-establish airway
- cut umbilicus
- keep warm until active
-encourage feeding and feed colostrum asap

302
Q

Fading puppy/kitten syndrome

A

Die when under 1-2 weeks of age
Multifactoral causes

303
Q

Septicaemia

A

-Colostrum (provides passive immunity) only absorbed via the gut in the first 48hrs
-high mortality

304
Q

Viral infection in neonates

A

Not common if dam vaccinated
-canine herpes virus
-FIV/FELV
-feline coronavirus
-feline panleukopenia virus

305
Q

Congenital abnormalities in neonates

A

Cleft palate
Hernia
Hydrocephalus

306
Q

Weaning puppies/kittens

A

From >2.5 weeks
Complete >5 weeks
Monitor for continued weight gain
Slowly introduce food (some mix with water to make a paste to start of with)

307
Q

Rabbits and hand rearing

A

-altricial (not developed)
-minimal disturbance - only for food and cleaning
-Kits suckle for 3-5 mins at the time and only 1-2 times in 24hrs
-dependant on does milk for 3weeks
-start solids between 2-3 weeks old
-weigh at 2-3 weeks old
-weaning at 6 weeks old
-kits need > Vit D and calcium vs adults

Hand rearing:
-death from enterotoxaemia is common
-transfaunation of gut flora from healthy parasite free adult
-use kitten milk replacers or 1-part full fat cows milk: 3parts condensed milk
-offer adult/weaning formulated dry foods from 2 weeks and attempt weaning from 3 weeks

308
Q

Guinea pigs neonates

A

Precocial young
Eat some solids within 24hrs
If hand rearing = 1 part condensed milk : 2 parts cooled boiled water

309
Q

Foetus development stages

A
  1. Ovary releases an ovum
  2. Sperm travels to the ovum which is in the fallopian tube
  3. The ovum is fertilised and divides into 2 cells - this takes 96 hours
  4. 20 hours later it divides into 4 cells
    5.144 hours later it divides into 8 cells
  5. 192 hours later it divides into a call of cells called the morula
  6. This is a total of 8-9 days by then the morula has moved towards the uterus
310
Q

Define ectoderm

A

Outer layer
Will form the skin and nervous system

311
Q

Define mesoderm

A

Middle layer
Will form several organs and the musculoskeletal system

312
Q

Define endoderm

A

Inner layer
Will form the lining of the GI tract and other visceral organs

313
Q

Zonary placenta

A

-surrounding band
-provides nourishment
-burrows into endometrium and receives blood from the uterine artery
-marginal haematoma = haemorrhage into uterine endothelium during implantation
-this haematoma breaks down during parturition
(Green discharge in the bitch)
(Brown discharge in the queen)

314
Q

What does prolactin do

A

Stimulates formation of milk from the mammary glands

315
Q

What does oestrogen do

A

Prepares and contributes to the growth and development of mammary tissue and prepares the uterus for parturition

316
Q

What does oxytocin do

A

Initiates strong contractions and causes milk to be released from mammary glands when neonates suckle

317
Q

What does relaxin do

A

Placenta produced hormone which causes cervix to relax

318
Q

Parturition
Stage 1

A

Variable in duration
Often depends on the experience of the bitch
On average lasts 1-2hrs

319
Q

Parturition
Stage 2

A

Cervix dilates
Contractions are more obvious
Noticeable straining
Time onset between straining and first foetus = 10-30mins
Uterine contractions increase in intensity
Onset abdominal contractions and propulsion of first foetus to be pushed through cervix into vagina
Puppy will appear, usually still surrounded by a thin but though membrane (amnion)
Sac is broken by dam as she licks pup to stimulate respiration - may need help in some cases

320
Q

Parturition
Stage 3

A

Foetal membranes and placenta pass
Bitch may eat placenta
Dark green discharge may be seen following parturition
May happen for up to a week - considered normal

321
Q

Parturition
Stage 4 (puerperium)

A

Reproductive tract returns to its normal state
Bitch should be checked to ensure she’s recovered
Offer her a small amount of food and water
Take her to the toilet
Clean whelping area
Interference should be minimal
Weigh puppies and check for abnormalities
