Livestock Production, Dairy and Poultry Management
Livestock production, dairy and poultry management tests breeds, housing, feeding systems, lactation, reproduction management and poultry incubation. Questions often ask for the management step that prevents a production loss.
Core rules
- Dairy: record heat and milk yield, dry period about 60 days, lactation curve peaks around 6–8 weeks then declines; clean calving pens reduce infection.
- Breeds: Sahiwal and Red Sindhi are dairy cattle; Murrah and Nili-Ravi are buffalo; Holstein Friesian and Jersey are exotic dairy; Gir is dairy-type.
- Poultry: incubation 21 days for chicken, 28 for duck; temperature about 37.5–37.8°C, humidity and turning matter; brooding temperature starts near 33–35°C and reduces weekly.
- Housing: ventilation, dry bedding, space, clean water; heat stress reduces feed intake and fertility.
- Biosecurity: all-in/all-out, disinfection, limited visitors, rodent control.
Worked example
A buffalo herd has a calving interval of 16 months. Reasoning: the target is about 12–13 months; each extra month costs milk and calves. Check heat detection, postpartum uterine health, body condition and nutrition. Adding more concentrate without improving heat detection may raise milk but will not fix the calving interval, because the main loss is missed or late insemination.
Traps
Do not confuse incubation periods of chicken and duck. Do not use the same brooding temperature for all ages. Do not assume high milk yield alone means good fertility. Do not ignore heat stress when diagnosing poor production.
