High-efficiency goat breeding with special feed
Goats are small and have a slow growth. It is very important to increase the number of goats, increase the survival rate of goats and increase the growth rate to improve the economic benefits of raising sheep. In recent years, the Yangyang Research Group of Animal Science Department of Nanjing Agricultural University developed a goat special feed. According to a special goat feed experiment for 75 days in Qidong City and Jiulong Township, Jiangsu Province, the method and amount of feed used: 20 g (every sheep per day) mixed in a small amount of concentrate, or about 0.5 kg of grass powder at night Add a little water and stir to feed. Type I formula: 10 grams of special feed + concentrate 100 grams; type II formula: concentrate 100 grams: control; grazing rearing. The results showed that the daily weight gain of goats fed formula I in the coastal township was 42.01% higher than that of the control group, and the feed rate of the type II goat was 22.48% higher than that of the control group. Jiulong Township daily weight gain I type increased by 80.32% compared with the control group. The formula I of Haihai Township I increased the benefit by 27.87 yuan compared with the formula II, the formula I gained 33.59 yuan compared with the control group, the formula II increased by 5.70 yuan over the control, and the Jiulong township I formula increased by 165.00 yuan compared with the control group. In addition, a specialized family of Haihai Township reared 210 goats, and in the rainy season, 43 lambs were killed (21.39% of the total) due to diarrhea. However, with the addition of special feeds, all sheep will recover after a week, and will often be added later in the mix. Rarely occurs. Another professional household raised 408 sheep and had 96 lambs. 64 died due to diarrhea, accounting for 66.7%. 182 lambs were born in the spring and 169 lived after supplementing special feeds, and the survival rate was over 90%. As described above, the feed has the functions of balancing nutrition, promoting growth, and fattening, and has the effect of antidiarrheal and anti-pulling. The use of bred sheep after weaning, fattening sheep before sale, and adult ewes at the stage of pregnancy and lactation is most effective. It is safe, convenient, economical, and effective.
