Goat Management Characteristics Goat population worldwide is over 350 million U.S. population is between 2 & 3 million Becoming more popular as people move to more rural areas Relatively inexpensive to purchase and reproduces efficiency Having 2- 3 offspring per year Don’t demand specialized housing or feedstuff Patterning Get does into a routine. Feed at same time and place where you can pen the animals in a small enclosure. Easily caught and handled from there. Reproduction Seasonal Breeders Length of daylight influences the secretion of hormones that affect the estrous cycle Seasonal species are responsive to melatonin Hormone produced by the pineal gland Response to declining periods of light Breed in the Fall 80% of all does come into heat between Sept 1 and Dec 31 Reproduction 3 systems for breeding Pasture Breeding AI Hand Mating Pasture Breeding Does and Buck put into one field Very little labor and results in a large percentage of does conceiving Have no control over when does are bred AI Growing in popularity Frozen semen is thawed and placed into the reproductive tract of the doe Done by using a plastic insemination pipette Heat detection is very important Cost is higher Can breed to superior bucks Insemination site We want the tip of the catheter to be well inside the cervix, but not penetrate completely into the uterus. Reason-bacterial contamination Take catheter and insert Place catheter in cervix Hand Mating Buck is kept in a separate pen from the does As does come into heat they are turned into pen with buck Breeding is observed, then doe is removed from buck and return to pen Gives you precise breeding dates Separate buck pen and shed, and more time is involved Parturition Gestation period is between 145- 155 days Kids should have navels dipped in iodine to prevent infection Make sure kids receive colostrum Don’t touch kids right after birth Kids are weaned at 3 months Disbudding Removal of the horn buds from a kid Two methods Chemical Disbudding iron Castration Done before 12 weeks 3 methods Knife Burdizzo Elastrator Knife Burdizzo Elastrator Identification 4 different methods Tattooing Neck chains Branding Ear notching Hoof trimming Removing the excess growth that occurs at the toes, heels, and sidewalls of the hooves Should be done every 6-8 weeks Hoof Trimming Parasites Internal Parasites one of most economically important constraints in raising livestock Animals certain to exposure of worms Confinement Pasture-based Results Decrease in productivity death Controlling Parasites Worms are a major parasite within goat industry Should be dewormed on a regular basis About every 6-8 weeks Receive an injection of Clostridium Perfringes, Types C & D and Tetnus, once a year Deworming 3 types of dewormers Avermectin Benzimidazoles Imidazothiazole Avermectin Clear dewormers Ivomec, Dectomax, Cydectin Not effective against tapeworms Benzimidazoles White dewormers Safeguard Effective against tapeworms Can cause abortions Imidazothiazole Tramisol May cause abortions The “safe” and “toxic” levels are very close, making product dangerous Fecal Float Way to identify what type of worms goats have and what you need to vaccinate with Use a Modified Wisconsin Procedure Create a sucrose solution Combine 454g granulated sugar with 335mL of water Heat the solution until the sugar is completely dissolved and the solution is clear Fecal Float Fecal samples are collected and weighed 3g of each sample is measured and suspended into 20 mL of the sucrose solution in a waxed paper cup Solution is stirred until solution is completely dispersed and then poured into a second cup Fecal Float Liquid is poured into a 15 mL test tube until slightly raised above the top of the test tube then topped with a cover slip Allow to sit for 3-6 hours then observe under a microscope The FAMACHA© System Eye color chart with five color categories Compare chart with color of mucous membranes of sheep or goat Classification into one of five color categories: • • 1 – not anemic 5 -- severely anemic Examine in sunlight Open as shown - for a short time only Look at color inside lower eyelid Barber pole worm egg Haemonchus adults in the abomasum Other Diseases Blackleg Bloat Bottle Jaw Coccidiosis Colic Enterotoxaemia Foot and Mouth Disease Foot Rot Other Diseases Johne’s Disease Thickening of intestine Have to be slaughtered (no cure) Pregnancy toxemia Mastitis Tetanus Urinary Calculi
