Write a note on cattle feed.

Cattle feed must provide balanced nutrition comprising roughages, concentrates, minerals, and vitamins to maintain health and optimize production. Roughages including green fodder (berseem, lucerne, maize), dry fodder (wheat straw, paddy straw), and silage form 60-70% of a dairy cow's diet, providing fiber essential for rumen function and digestive health. High-producing dairy animals require concentrate mixtures containing energy sources (maize, barley, wheat bran), protein supplements (soybean meal, cottonseed cake, groundnut cake), and mineral mixtures to meet increased nutritional demands—typically 1 kilogram of concentrate per 2.5 liters of milk produced above maintenance requirements.

Scientific feed formulation considers the animal's age, body weight, production stage, and purpose (milk production, meat production, or draught). Lactating cows need calcium and phosphorus supplementation to prevent milk fever, while calves require colostrum within the first 6 hours of birth followed by gradual introduction of calf starter feed. Common feeding practices include offering green fodder twice daily (morning and evening), providing concentrates before milking to establish routine, ensuring constant access to clean drinking water (40-60 liters daily for dairy cows), and supplementing with mineral mixtures to prevent deficiencies. Balanced feeding not only increases milk yields by 15-20% but also improves reproductive efficiency, reduces metabolic disorders, and extends productive life. Farmers practicing fodder cultivation alongside cattle rearing reduce feed costs significantly while ensuring quality nutrition, making dairy farming economically viable even with small herd sizes of 3-5 animals.
