Concentrated feed for barren sows

Abstract

The invention relates to a concentrated feed for barren sows, and per 1,000 parts by weigh of the concentrated feed comprises the following raw materials in parts by weight: 490 to 510 parts of puffed bean pulps, 240 to 260 parts of puffed soybeans, 70 to 90 parts of fish meals, 3 to 5 parts of microbial ecological agents, 15 to 25 parts of glucoses, 35 to 45 parts of mountain flour, 35 to 45 parts of calcium hydrophosphate, 10 to 20 parts of table salt, 3 to 4 parts of sodium bicarbonate, 3 to 7 parts of composite trace elements, 0.6 to 0.7 parts of chromium picolinate, 5 to 8 parts of compound amino acid, 0.006 to 0.01 parts of folic acid, 0.9 to 1.5 parts of boar composite many-dimensions, 0.3 to 0.4 parts of vitamin E, 1 to 2 parts of vitamin C, 0.9 to 1.5 parts of beta-carotene, 1 to 2 parts of flavoring agents, 0.09 to 0.15 parts of phytase, 1 to 2 parts of ethoxy quinoline, 2 to 3 parts of choline chloride, and the balance of carriers. In case of adding 30 percent of the concentrated feed into daily fodders for sows, the interval time from ablactation to oestrus can be shortened, thereby improving the oestrous rate, litter size and the like of the sows.

Description

technical field [0001] The invention belongs to the technical field of sow feed, and in particular relates to a special concentrated feed for empty pregnant sows, which can promote early estrus and more ovulation of empty pregnant sows. Background technique [0002] The whole reproductive cycle of sows (pregnancy ~ parturition ~ lactation ~ weaning ~ mating ~ pregnancy) is an interlocking process. The previous nutritional management will affect all subsequent stages, so the best nutrition must be provided at each stage. Optimum nutrition can maximize reproductive performance. Compared with the pregnancy and lactation period of sows, the nutrition of sows during the empty pregnancy period has not been given due attention. In actual production, due to the lack of special feed products for sows during the empty pregnancy period, it is common for sows to not estrus or delay estrus after weaning , repeated infertility and low litter size have become a major problem that plague...

AI Technical Summary

Problems solved by technology

Although the above measures can restore ovarian function, promote the normal development of follicles, and promote the effect of estrus and ovulation, there are also some defects: as the price is relatively expensive; it can only be treated individually; Improve the birth quality of newborn piglets, etc.
