1. Several situations where pigs need refueling 1Different developmental stages: from suckling piglets to weaned piglets, from weaned pigs to growing pigs, from growing pigs to finishing pigs; 2 Different types of materials: from pellets to powder, from wet stuff to raw dry stuff, etc. 3 Change feeds from different manufacturers; 4 Change in the number of feedings: For example, 4-6 feedings from the piglet stage to 3-4 feedings on the finishing pig stage. 5 When the feed is self-aligned, the main monomer material changes. 2. The specific method of feed replacement Take 1/4 of the new material and old material every day and replace it in 4 days. The method is: the first day of the new material l/4, the old material 3/4, the next day the new material 1/2, the old material 1/2, the third day of the new material 3/4, the old material l/4, the first All four days are new materials. When mixing, the proportion of energy feed (such as corn) in the feed gradually increases as the pig grows, and the proportion of protein feed (such as bean cake) gradually decreases. For example, if the proportion of corn in the feed formulation is increased from 60% to 70%, the transition will take 4-5 days, and the daily increase will be 2.0%-2.5%; the soybean cake will be reduced from 20% to 15%, and it should be reduced by 1% per day. Others The use of wheat bran, fine clams and other raw materials to adjust, using concentrates from the distribution of full-priced material is also true. When using the transition method for refueling, always pay attention to the pig's feeding and defecation conditions. It is best to feed only 7 or 8 points per meal. In addition, it is also necessary to carefully raise and reduce other stress.
