Skillfully feeding oil can speed up piglet growth

Piglets have the characteristics of fast growth and rapid metabolism, and have high nutritional requirements for the diet. Such high energy requirements, if the corn and bean cake-based diet is difficult to achieve, therefore, it is necessary to add a certain proportion of oil. The experimental study confirmed that the energy and protein utilization rate increased after the addition of oil and fat in the piglet diet, and the growth rate of the piglets was significantly accelerated. Especially for piglets with lower birth weight, the effect is more obvious. In addition, oil can also reduce feed dust, reduce heat shock, improve feed flavor, improve feed appearance, and reduce feed heat.

Fatty feeds include animal and vegetable oils. Animal oils such as lard, butter, fish oil, etc., the content of unsaturated fatty acids in lard is higher than that of butter. Fish oil is cheap but easy to rancid and difficult to preserve. Vegetable oils such as rapeseed oil, cottonseed oil, corn oil, and the like. In general, the optimal ratio of fats and fats in piglet diets is 10% to 15% in the early period and 5% to 6% in the later period. Practice has proved that the application of vegetable oil and animal oil is better than single application. It is better to mix vegetable oil and animal oil in a ratio of 1:1 or 2:1. In daily production, the halogen oil of the braised meat store and the lard as a by-product of the meat processing plant are superior and cheap animal fats. The researchers mixed soybean oil with short-chain saturated coconut oil in the 21-day-old weaned pig diet. The piglets fed soybean oil and coconut oil showed higher daily gain and feed compensation.

2. Add method a68 China feed industry information network - based on feed, service animal husbandry

(1) Join directly. The oil is added to the feed evenly according to the proportion. Because the grease is sticky, it should be heated and melted first, then added with less powder, evenly mixed, gradually enlarged and diluted, and finally mixed with other parts of the remaining diet. Never add fats and premixes and additives at the same time to avoid the formation of small particles of grease and these additives to affect feed uniformity. You can add the oil first, add the additive after mixing well, or add the additive and mix well before adding the oil.

(2) Add after adding high oil. The pulverized corn is formulated into a high-oil feed containing 10% or 20% oil, and then added to the full-price material in an appropriate amount according to the ratio of corn and oil required.

(3) Spray addition. The spray can be used to evenly spray the grease onto the surface of the pellet feed. If the pelleted feed is conditionally produced, 30% of the added fat can be added to the pellet feed, and 70% can be sprayed onto the surface of the pellet to improve palatability.
