Adding fat to pig feed

1. The amount of fat added and the effect of feeding are increased by 2% to 3% in the feed for piglets, and the weight gain is increased by 10% to 14%, and the unit weight consumption is reduced by 8%-10%. Adding sugar and fat to the starter diet can increase palatability and benefit piglets as soon as possible. The addition of 3%-5% to the growth and finishing pig feed can increase the weight gain by 5% and the feed consumption by 10%. Addition of 2% to 6% of pregnant gestation sows can generally be added after 2 weeks of gestation. The live weight of neonatal piglets can be increased by 10% to 12%, and the number of survivors of suckling piglets can be increased by 1.5 to 2 per sow per year. For example, if the amount is increased to 10% before 5-15 days before delivery, the effect is even more pronounced. The amount of lactating sows added was 5%-10%, the sow's lactation was increased by 10%-30%, and the weaned weight of piglets was increased by 15%. Based on the addition of the monthly fat during gestation, the addition of lactation can shorten the interval between weaning and estrus, and increase the number of litters to 0.4.

2, adding methods can be added to the lard, butter, soybean oil, etc., according to the amount of boiled oil soup by adding a certain amount of chopped green onion and flavoring directly mixed feed in feed. This method is suitable for pig farmers who keep a small amount of livestock. Grease the grease into a thick paste, add a certain percentage of quail feed or cornmeal, stir well (put a certain amount of antioxidants) in the summer on the cement floor, mix well, dry, winter can be dried, or with oil The machine presses into cakes, and the cakes are crushed and added to the feed according to the feed formulation.

3. Precautions Fat must have no specific odor, and no contaminated good quality fat can guarantee feed quality and palatability. Adding fat must add vitamin B12 and yeast feed in an appropriate amount to facilitate the absorption and utilization of fat and prevent the occurrence of fatty liver disease. Another added in the feed vitamin C, 200-300 mg / kg feed can promote growth and improve feed conversion. When directly brewing and feeding, be sure to pay immediately to prevent rancidity. The storage time of dry feed for adding fat should not be too long, generally 5-7 days. The shorter the summer time, the better. When adding, you must start with a small amount to the right amount to prevent diarrhea caused by a large amount. Add fat to give more water, which will help fat absorption and utilization. The fat is best to use vegetable fats, because the vegetable oil is better than animal oil in the digestion and absorption, the lard in the animal oil is better than the butter, and it is better to use the vegetable oil and the animal oil in a ratio of 3:1 and the effect is better. For lean-finishing pigs, appropriate amounts of fat may be added in the early stage of fattening, and fats should not be added in the later stages of fattening so as to increase the lean meat percentage.
