Feeding management of lactating sows
1. 7 days before delivery, sows enter the farrowing house, keep the delivery room dry, clean and hygienic, and gradually reduce the feed amount, and reduce or not reduce the feed for those who are in poor condition;
2. Before birth, sow udder and pudenda are washed, and then 0.1% potassium permanganate aqueous solution is used for scrubbing and disinfection; after birth, a needle of green and streptomycin is injected to prevent perinatal diseases; in high temperature season, cod liver oil-antibiotic mixture is injected intramuscularly to sow one week before birth to prevent high temperature syndrome;
3. Sows in the process of delivery, to have careful care, to keep the environment quiet, clean, dry, warm in winter and cool in summer, to prevent high temperature delivery room, if there is dystocia, usually with oxytocin intramuscular injection, the use of doses of 10-20 units each time, if 30 minutes after the birth has not yet been produced, then to carry out artificial delivery; It is best to clean the uterus and inject prostaglandin (PGF2α2 ml intramuscular injection at 36-48 hours after the last farrowing) to help the lochia discharge and uterus reset, and also to promote the sow to estrus after weaning.
4. Sows are not fed with feed on the day of farrowing, but only bran saline or bran electrolyte water. The feeding amount is gradually increased within one week. When the feeding amount is normal, the feed intake of sows shall be increased to the maximum extent. Feeding shall follow the principle of "less feeding and frequent feeding", and moldy feed shall be strictly prohibited. Sufficient clean drinking water shall be provided during lactation period to prevent constipation of sows and affect feed intake.
5. To check the sow's breasts in time, the sow mastitis should take timely measures to treat;
6. 2-3 days before weaning sow feed reduction, feeding less or no feeding on the day of weaning, and appropriate reduction of water consumption, to be weaned 2-3 days after the breast wrinkles, can increase feed, start to stimulate feeding, so as to avoid weaning sow mastitis.

Vitamin d deficiency, calcium and phosphorus metabolism disorders in geese
Vitamin D (VD) deficiency or calcium and phosphorus deficiency as well as calcium and phosphating disorders can cause osteoporosis, rickets in young geese or osteomalacia in adult geese. The disease is a nutritional bone disease, which can occur in geese of different ages. Clinically, it is often found in 3-week-old goslings. The main manifestations are growth stagnation, bone deformation, limb weakness, soft feet and paralysis. When the adult goose is sick, the number of eggs is reduced or soft-shell eggs are laid. In addition, the disease can also induce other diseases, often causing certain economic losses to the goose industry. 1. Disease

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 of raising chickens. 2. Raw materials
