How to choose high quality teaching materials

Evaluation of the teaching material generally refers to whether the feed intake and growth rate of the suckling pig continue to increase, and whether the diarrhea rate is reduced. Usually, under the conditions of pig breeds and software and hardware management techniques, the suckling pigs after eating the feed material showed “like to eat, digest, and feed intake”, especially after the transfer of the material to another product. During the week, the rate of nutritional diarrhea was less than 20%; the feed conversion rate was about 1.2; the average daily weight gain was 250g; and the feed intake was more than 300 days. Therefore, people must pay attention to the choice of teaching materials. Practice has proved that the quality teaching material should have at least the following characteristics: jUg China Feed Industry Information Network - based on feed, serving animal husbandry

1. Suitable for digestion and nutrient absorption. Among them, the low levels of anti-nutritional factors and allergens and the improvement of feed digestibility are the key to improving feed intake of suckling pigs. The feed has a good performance after being digested and re-deposited. At this stage, the daily weight gain of suckling pigs has an extraordinary significance for the whole growth performance of commercial pigs. jUg China Feed Industry Information Network - based on feed, serving animal husbandry

2. Good palatability. Suckling pigs like to eat, and the feed intake is very large, so they can have good daily gain indicators. jUg China Feed Industry Information Network - based on feed, serving animal husbandry

3. The nutrition is comprehensive and balanced. The nutrients of various raw materials are different and the digestibility is also different. Therefore, it must be scientifically formulated and carefully prepared. jUg China Feed Industry Information Network - based on feed, serving animal husbandry

4. The incidence of pigs is low. In particular, the incidence of diarrhea should be minimized. Indigestion feed, which enters the large intestine after passing through the small intestine, is a good medium for bacteria in the large intestine, leading to rapid propagation of bacteria in the large intestine, which is the main cause of diarrhea in suckling pigs. In the case of nutritional diarrhea, in addition to protein, electrolytes, vitamins, amino acids and other nutrients are also lost with "thin". Many feed companies attempted to solve diarrhea by adding antibiotics to their feed, which turned out to be futile. jUg China Feed Industry Information Network - based on feed, serving animal husbandry

5. No weaning stress phenomenon. The occurrence of weaning stress will cause the piglets to lose weight after weaning and the growth is stagnant. In order to restore the normal growth rate of pigs as soon as possible and make up for the loss of weaning stress, it is necessary to improve the feeding conditions by increasing the feeding of weaned pigs. jUg China Feed Industry Information Network - based on feed, serving animal husbandry
