MANAGEMENT (GOATS) (read)

A
  • It is usual to see an offspring at the side of the mother even when rearing a kid of its own
  • their pack character is so very evident, w/ the oldest buck or doe on the highest part of the sleeping area.
  • they also have maintained their mountainous character.
  • goats prefer an ELEVATED AREA FOR RESTING. the arrangement and feature of the housing, including management practices, must then be adapted according to these characteristics
  • can be expected to live up to 13 - 15 yrs, w/ an average economic lifespan of 6 - 8 yrs.
  • in the phils., does come in-heat yr round w/ an average kidding interval of about 8 - 9 mos.

HOUSING (GOATS) (read)

A
  • All goats are afraid of rain and wetness, as these make them prone to pneumonia
  • they prefer to sleep in ELEVATED areas, therefore elevatedsleeping platform, like stair-type arrangement, and must be provided
  • flooring should be included and elevated at least about 15 to facilitate cleaning and drainage
  • separate pens should be provided for lactating does, kids, growers and bucks
  • the buck pen should be placed in such way that it will always be visible to the breeding does yet far enough to avoid transfer of the typical goat smell in case of lactating does when milk is to be sold

  2. if colostrum in the udder is not fully consumed by kid, stopping (manually milking out excess) will be necessary to prevent mastitis
  3. placenta must come out w/in 24 hrs from expulsion of fetus
  4. tie the umbilical cord w/ sterile string and apply disinfectant (tincture of iodine) on the cut portion
  5. allow the kids to suckle for first 4 to 5 days. if the doe is to be milked, separate the kids from the mother and start feeding using baby bottle (8 oz. size)
  6. if doe is not to be milked, the doe can be taken out of the pen for feeding and returned to the kid3x a day and whole night
  7. does weaned 4 - 5 days, return to heat after 1 - 2 mos.
  8. 2 services a day for 2 days is optimum, when doe comes to heat introduce it to buck not vice versa
  9. higher conception is accomplished in secondary heat.
71
Q

milking (read)

A
  1. like in cattle, milking periods must be established and strictly adhered to. process should not be advance or delay
  2. unnecessary changes in routine should be avoided same personnel should be assigned, because goat can withhold their milk

72
Q

care of weanling and growing kids

A
  1. placed all weaned kids in separate pen, if possible according to size
  2. male kids intended for meat, castrate as early pereferrably w/ in the 1st month

73
Q

breeding

cycle of type in goat

A

polyestrus

74
Q

buck to doe ratio

A

1: 35

* older bucks can cover up to 35 doe services per yr.

75
Q

best breeding time of goat

A

daily during estrus

*best breeding age will be 10 - 12 mos. depending on desired weight.

76
Q

it is very common in crossing natives w/ large pure-breeds due to the invariability large size of the unborn kids

77
Q

failure to come in heat;
common problem most particularly w/ high producing does;
several hormones, prostaglandin, progesterone sponges and implants and pregnant mare serum (PMS) have been used w/ varying rates of success;
routine administration of oxytocin right after kidding and before weaning (5 days) aids in faster expulsion of the placenta, uterine fluids in the rapid regression of the uterus;
routine viutamin A, D, E supplementation to breeding herds also contributes to reproductive well-being

78
Q

a method of breeding w/ enables goat raisers to utilize far away proven bucks for impregnating their in-heat does;
IN THE PHILIPPINES IT HAS SUCCESSFULLY DONE AT national rural life center (NLRC) in dasmarinas, cavite where the kid goat, A.1 was born;
this is also being tried in Iloilo, w/c receives shipments of frozen goat semen from NLRC

A

GOAT ARTIFICIAL INSEMINATION

79
Q

this will cause lameness and make it prone to foot rot. bucks refuse to mount when having sore feet;
rose pruner and small curved knife are adequate tools

A

HOOF TRIMMING

*goats hooves under confinement are usually overgrown

80
Q

DEHORNING (READ)

A

especially in milking, dehorning is essential;
a dehorned animal is more docile than a horned one. it will also eliminate unnecessary wounds due to fighting;
dehorn when horn buds appear (2 - 4 mos.) using hot iron cautery;
1/2 inch GI pipe is an effective and cheap material for cauterizing;
chemical cautery is not preferred because kids tend to lick one another and may therefore lead to cauterized or burned tongues

81
Q

CASTRATION (READ)

A
  • castration of unwanted male goats is preferred w/in the 1st month of age
  • castrated male grow faster than uncastrated males and are free of the goaty male odor
82
Q

TATTOOING, EAR NOTCHING AND OTHER FORMS OF IDENTIFICATION (READ)

A
  • in order to keep track of individual animals, a postive identification is needed. no recording is possible w/o this.
  • ear notching is more common because of permanence and easy identification. refrain from using plastic tags.
  • tattooing causes no deformities but requires special tools that may be costly
83
Q

RECORDING (READ)

A
  • for a good breeding herd program, proper and well-kept recording system is necessary.
    the record must reflect all the essential data of individual animals

fever vesicles, erosion in between hooves, coronary band junction between skin and hoop, teats and udders oral mucosa and tongue
raw ulceration follow rupture of vesicles, stingy or foamy salvation, smocking of the lips, difficulty in feed ingestion; staggering fait and lameness.
abortion in pregant animals

Prevention
immediate notification of the authorities. designation of quarantine areas w/ virudical agents (commercial disinfectant or lye caustic soda);
animals should be kept on dry ground and lesions treated w/ mild antiseptic (5% formalin);
mass immunization and effective restriction in movement of animals and carriers is necessary

A

FOOD AND MOUTH DISEASE (FMD)

106
Q

mode of tansmission
ingestion of contaminated feed and water. aborted fetus, fatal membrane, placenta, urine and uterine discharge are main sources of infection. infected males may transfer disease through natural/artificial breeding

symptoms
infertility, abortion, retained placenta, persistent vaginal discharge. in males, swollen and painful testicles w/ subsequent infertility sterility.

Prevention
blood tests and removal of infected animals;
vaccination may be tried;
antibiotic medication is found to be impractical

A

BRUCELLOSIS

107
Q

mode of transmission
ingestion of inhalation of infective agent. maybe normally present in the nasopharyngeal area but predisposition causes flare-up of infection

Symptoms
high fever, loss of appetite
respiratory distress, salivation, nasal discharge, swelling of throat and brisket congestion of mucous membrane, diarrhea becoming bloody later

Prevention
prophylactic vaccination
removal of predisposition when possible
early treatment w/ parental antibiotics and sulfa drugs

A

HEMORRHAGIC SEPTICEMIA

108
Q

mode of transmission
infection initiated by trauma of the body and oral mucosa. cases in larger ruminants may be source of infection in the area

Symptoms
sudden death in acute cases;
less acute: depression fever, rapid respiration and suspended ruminatism;
typically, not painful swelling in thigh and leg muscles. crackling sensation on palpitation of swelling due to gas in tissues

Prevention
lameness in affected limb;
vaccination;
cremation of carcasses;
early isolation and treatment w/ massive doses of antibiotics
109
Q

mode of transmission
direct or indirect die to introduction of organism in wounds. castration, old ulcerating wounds, dehorning complications. not contagious to other animals

Symptoms
early stages characterize by rigidity and stiffness of muscles, stilthy gait.
late stages: w/ tetanic convulsions,
prolapse of 3rd eyelid, stiff tail, head and neck thrown back; hyper-excitability

Prevention
bloat and other nervous signs. treat wound w/ oxidizing antiseptic (hydrogen peroxide) until completelyhealed; use clean instrument castration, dehorning

110
Q

mode of transmission
commonly transmitted through direct infection w/ parasitic larval stages through herbages, less commonly through skin penetration and intrauterine infcetion in some species

Symptoms
poor body condition: anemia, diarrhea, potbelly and weakness

Prevention
regular deworming w/ effective anthelmintics (tetramisole, parbendazole, thiabendazole, pyrantel);
pasture rotation and improve feeding practices

A

PARASITIC GASTROENTIRITIS

111
Q

mode of transmission
infection w/ the parasite in the larval stage through herbage

Symptoms
as in parasitic gastro-enteritis for general signs;
specific symptom include persistent husky, coughing, respiratory distress

Prevention
regular deworming w/ tetramisole albendazole or exfendazole;
general prevention as parasitic gastro enteritis

A

PARASITIC PNEUMONIA

112
Q

mode of transmission
through ingestion of plant mites w/c are intermediate hosts

Symptoms
some as other internal parasitism, passage of tapeworm segments in the feces

Prevention
regular deworming

A

TAPEWORM INFECTION

113
Q

mode of transmission
direct infection through ingestion of parasitic stage in grasses. presence of this stage related to avail ability of snail host;
common in low-lying communities w/ water logged areas, rivers, streams, and stagnat pools

Symptoms
similar to parasitic gastro enteritis

Prevention
regular deworming w/ flukecides, control of snail hosts; pasture improvements, keep animals away from known infected sources of herbage;
deworming at proper intervals (3-4 times a yr) is the only practical approach;
consult veterinarians for proper drug, dosage and intervals

A

LIVERFLUKE INFESTATION

114
Q

mode or transmission
direct or indirect w/ infested animals or indirectly through the environment of facilities

Symptoms
constant scratching and rubbing;
scurfy coat (danfruff) and encrustation of exudates w/ scabby deposit. loss of hair, raw skin and bruises in severe infestation;
animals become unthrifty, poor thriving, weak and anemic

Prevention
use insecticide (asuntol, ciodrin, diazonin, neguvon, supona, nankor, etc.)
in dust form solution, repeat treatment in 10-14 days to kill all nymphs w/ hatch out.
also, spray pens and lifter. isolate treated from untreated animals

A

LICE INFESTATION

115
Q

mode of transmission
direct or indirect contact w/ infected animals

Symptoms
marked itchiness and irritation w/ animals constantly rubbing or licking affected areas;
maybe patchy or generalized, skin becomes hairless, thickened or scabby.

Prevention
periodic examination to detct early cases. regular spraying w/ effective acxarides such as malathion, trichlorfon, fentnion;
diazonin, crotoxyphos or coumaphos;
interval of treatment should be 7-10 days w/ 2-3 applications to destroy mites that have hatched after each treatment

116
Q

mode of transmission
non-contagious

Symptoms
swollen left flank w/c is resonant when tapped. signs of colic such as uneasiness, difficult respiration, bloating and absence or rumen movements

Prevention
feed straw or fibrous diets before turning loose on lush pasture. punture rumen w/ large needle;
oils and fats (mineral oil. vegetable oil or to prevent foaming tallow) are satisfactory in the rumen. commercial antibloat preparations are avlinox, tympanol, and bloatyguard

117
Q

mode of transmission
non-contagious

Symptoms
signs appear from 10-36 hrs after dietary changes.
depression, loss of appetite, abdominal distention causing pain and discomfort. diarrhea develops.;
rapis respiration and pulse, in coordination, weakness, coma and health

Prevention
avoid sudden dietary changes. treatment generally changes. treatment generally unsatisfactory.
early cases may respond to high atibiotic levels given orally to reduce population of acid-forming bacteria, (acidosis) indigestion may be treated w/ anti-acids like baking soda (sodium bicarbonate), mg carbonate or mg hydroxide given orally in warm water (1gm/kg body weight) to neutralize rumen acidity. systematic acid requires intravenous injection of acid neutralizers like 5% sodium bicarbonate repeatedly given
