🔹 Animal Breeding Terms
- Inbreeding: Mating of related animals (↑homozygosity)
- Outbreeding: Mating of unrelated individuals (↑heterosis)
- Crossbreeding: Mating of different breeds (e.g., Jersey × Sahiwal)
- Grading up: Improving local stock by mating with superior breed
- Selection: Choosing best animals for reproduction
🔹 Key Animal Breeding Projects (India)
- Key Village Scheme (1952): Improvement of cattle breeds
- ICDP (Intensive Cattle Development Project): 1964–65
- National Project on Cattle & Buffalo Breeding (NPCBB): 2000–2011
- Rashtriya Gokul Mission: 2014 – Indigenous breed conservation
🔹 Fodder & Feed Science
- Silage: Fermented green fodder (maize, sorghum)
- Hay: Dried fodder (legumes, grasses)
- Urea Molasses Mineral Block (UMMB): Nutritional supplement
- Azolla: Protein-rich aquatic fern for animal feed
- Bypass fat/protein: Increases energy/protein without affecting rumen microbes
🔹 Milk Preservation & Testing
- Methylene Blue Reduction Test (MBRT): Detects microbial quality
- Resazurin Test: Bacterial load estimate in milk
- Phosphatase test: Checks adequacy of pasteurization
- Titratable acidity in milk: 0.13%–0.17% (as lactic acid)
