Matters needing attention when chicken is mixed with full-price feed
1. Make full use of local feed resources due to different crop varieties cultivated in different places, the types of feed are also different. In the spirit of adapting measures to local conditions and using local materials, we should make full use of local feed resources, especially those with low prices. In this way, the intermediate links can be reduced, the freight required for grain relocation can be reduced, and the source of feed can also be guaranteed. According to the survey, this measure alone can reduce feed costs by 3% and 5%. It is one of the effective measures to improve the economic benefit.
2. When the variety of raw materials should be diversified, several kinds of feed raw materials should be used as much as possible to achieve diversification, which can play a complementary role between feeds. It can not only improve the biological value of protein in feed, but also improve the palatability of feed, increase feed intake, improve the production performance of chicken flock, and maintain stable and high yield. Therefore, there is a proverb that "feed is diversified and eggs are laid more and bigger".
3. To maintain the relative stability of the feed formula, while meeting various nutrients, we should also maintain the relative stability of the feed variety and mix proportion, and do not suddenly change the feed variety and mix proportion. Because chickens are very sensitive to feed changes, suddenly changing the feed formula or changing a certain feed will reduce feed intake and rapidly reduce egg production. This is what the masses mean by "poor food does not lay eggs". Because of the composition, nutritional value and feed price of feed raw materials, feed changes are frequent, so it can only be said that it is difficult to achieve a relatively stable proportion of feed raw materials, absolutely stable. When keeping the feed relatively stable, if you plan to change the feed or matching ratio, it should be changed gradually to avoid unnecessary losses. How to change the feed gradually should depend on the size of the formula. Only by gradually changing the feed and making the chickens gradually adapt to the new feed breeds and new feed formulations, can the stable and high yield of chickens be maintained.
4. pay attention to feed hygiene countries all over the world pay great attention to feed hygiene, because feeding feed that does not meet the hygiene standards not only affects the health and production performance of chickens, but also its products (meat, eggs) can directly or indirectly harm human health.

Feeding management of lactating sows
1. Sows enter the delivery house for 7 days before delivery, keep the delivery room dry, clean and hygienic, and gradually reduce the amount of feed, and feed less or no less for those with poor body condition; 2. Wash the breasts and genitals of sows before delivery, then scrub and disinfect them with 0.1% potassium permanganate solution; postpartum injection of penicillin and streptomycin to prevent puerperal diseases In the high temperature season, the sow should be injected with cod liver oil-antibiotic mixture to prevent high temperature syndrome during the high temperature season. 3. Sows should be taken care of carefully during delivery.

Renal transmission branch of chicken
Renal infectious bronchitis is a pathological manifestation of chicken infectious bronchitis caused by coronavirus. In recent years, especially since last winter and this spring, the incidence of renal transmission in Shandong Province, especially in Qingdao has increased significantly, resulting in considerable economic losses in the chicken industry, especially in the broiler industry, which has aroused widespread concern. Renal transmission is not an independent disease caused by an independent virus, it is a special phenotype of the transmission virus strain in the urinary organs of chickens, or it is under specific environmental conditions.
