First 48 hours
critical period of newborn calves, kids, and lambs
Colostrum
provides immunoglobulins (passive immunity), energy, vitamins A & D, and acts as a laxative.
Omphalitis
Dip the navel in iodine to prevent _
3–5 days
After colostrum, transition to milk or milk replacer. For goats, natural suckling may be allowed for __, then kids are reared by bottle/bucket feeding to allow controlled milking of does.
2 weeks
Introduce calf starter at __(16–18% CP, 70–75% TDN). Clean water must be available early to stimulate rumen function.
Good hay or roughage stimulates papillae development
Creep feeding
Introduce __ by 2–3 weeks; use palatable concentrates and legume forages
Weaning Age of Cattle
4–5 months under traditional management; as early as 6–8 weeks in intensive systems if starter intake ≥1 kg/day
Weaning Age of Goats/Sheep
2–3 months if kids/lambs are eating forage/concentrates well
Deworming
May be needed from 10–14 days in high-risk environments
0.5–0.75 kg/day
raised on pasture with minerals; gain __
Cattle
First breeding at 15–18 months (60 days postpartum) (when 65–70% of mature BW).
Goats
Breed at 8–10 months if ≥15–20 kg
~20 cows
Young bulls (2.5 years) can serve
30–40 cows
mature bulls can serve up to
Bucks/rams
8–12 mos old serve ≤20; older animals ≥25.
Late gestation (last 1/3)
Nutrient needs rise sharply — supply higher energy/protein to prevent pregnancy toxemia.
Provide minerals, especially Ca and P; Vitamin A, D, E injections around 6–7 months (cattle).
Lactating animals
Twice-a-day milking; emphasize udder hygiene to prevent mastitis.
High-energy ration with sufficient protein and Ca for milk production.
Monitor BCS — avoid ketosis in early lactation
Dry period (60–90 days)
Goats: milk declines after 3 mos; drying-off at 6–8 weeks pre-kidding
Allow udder tissue recovery, body reserve replenishment.
Feed controlled-energy diets to prevent metabolic disorders at next calving/kidding.
Vaccinate against diseases (e.g., coliform mastitis, clostridial diseases).
Early lactation (0–70 DIM)
High-energy, high-protein diet to support peak milk yield.
Monitor for metabolic diseases (ketosis, milk fever, displaced abomasum).
Mid-lactation (70–200 DIM)
Focus on maintaining milk yield and BCS recovery
Late lactation (>200 DIM)
Milk yield declines; prepare for dry period
Milking management
Pre-milking teat sanitation, dry wiping, post-dip after milking.
Machine maintenance and proper vacuum levels to prevent mastitis.
Monitor somatic cell counts (SCC) as indicator of udder health
Cows
60–90 days dry period for udder regeneration.
Goats
Milk yield declines after 3 months; drying-off 6–8 weeks before next kidding.
Dry Period (Dairy Cows and Does)
Management: Shift to lower-energy rations, deworming, hoof trimming, vaccinations
Hoof Trimming
Frequency: at least 1–2×/year in confined animals; less in extensive grazing where natural wear occurs.
Benefits: prevents lameness, improves feed intake and fertility, reduces infections like foot rot.
Technique: trim claws level with sole, restore normal shape; disinfect if lesions are present
Disbudding/Dehorning
prevents injuries, facilitates handling, reduces feed bunk space needs
Disbudding
Ideal before 3 weeks (kids) or 2 months (calves), before horn core attaches to skull.
Dehorning (older animals)
more invasive; should be avoided if possible
Castration
Why: prevents indiscriminate breeding, improves meat quality, reduces aggression
<6 months
Castration of Cattle
Goats/Sheep
2–4 weeks (elastrator); after 4 mos, use surgical/Burdizzo
Elastrator rings
best device in castrating very young animals
Burdizzo
a veterinary instrument, a type of castrator, that uses a large clamp to crush the spermatic cords and blood vessels of male farm animals without cutting the scrotum
Elastrator
a tool used with a rubber band to perform banding, a bloodless castration method for young livestock like sheep, goats, and calves, as well as for tail docking. The rubber ring cuts off blood flow to the testicles, causing them to atrophy and fall off within a few weeks
Traditional
Calves weaning 4-5 months
2–3 months
Kids/Lambs weaning period
Identification records
birthdate, parentage, tag/brand.
Production records
milk yield, weight gain, body condition, slaughter weights.
Reproduction records
heat detection, breeding dates, conception, calving/kidding.
Health records
vaccinations, deworming, disease treatments, mortalities.
Feeding records
feed rations, grazing schedules, feed costs.
Financial records
sales, expenses, profit/loss.
