Feed additive with effect of improving sow farrowing capacity

Abstract

The invention relates to the technical field of breeding and discloses a feed additive with the effect of improving a sow farrowing capacity. The feed additive is prepared from leek seeds, bitter melon seeds, loofah seeds, pumpkin seeds, flatstem milkvetch seeds, feather cockscomb seeds, chastetree fruits, fructus rosae laevigatae, fructus cnidii, glossy privet fruits, semen abutili, cluster mallow fruits, chingma abutilon seeds, semen cuscutae, bryozoatum, actinolite, broken pine pollen, lactic acid bacteria, fig polysaccharide and a compound enzyme. The feed additive has a small use amount, does not contain any toxic reagent and antibiotic, does not cause residual, improves disease resistance of breeding pigs, reduces a sow disease rate to 0-2% and increases a farrowing mount of each sow every year by 3-5. Through use of the feed additive, the birth weight of a piglet is 0.9 to 1 .1kg, a weaning piglet survival rate is 99%, the number of farrowing of the sow in the whole life is increased by 1-2, a replacement ratio is reduced and economic income is increased by 12.7%.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a feed additive for improving the litter ability of breeding pigs. Background technique [0002] Breeding pigs are boars and sows used for breeding, but with the extensive use of hormone feed additives and drugs in the traditional breeding process, the resistance of bacteria to drugs has increased, the disease resistance of breeding pigs has decreased, and the breeding time has shortened. The service life of boars is generally controlled at about 2 years, and the annual culling rate of boars is about 50%. In traditional pen breeding, sows generally use 7 to 8 litters, and the annual renewal ratio is 25%. Factory limited breeding, sows generally Using 6~7 litters, the annual elimination rate is 30~35%. Coupled with the abnormal elimination of low production performance, no estrus, and suffering from reproductive disorders, the elimination rate is even higher, which signif...

[0002] Breeding pigs are boars and sows used for breeding. However, with the extensive use of hormone feed additives and drugs in the traditional breeding process, the resistance of bacteria has increased, the disease resistance of breeding pigs has decreased, and the breeding time has shortened. The service life of boars is generally controlled at about 2 years, and the annual elimination rate of boars is about 50%. In traditional pen breeding, sows generally use 7 to 8 litters, and the annual renewal rate is 25%. Factory limited breeding, sows generally Using 6~7 litters, the annual elimination rate is 30~35%. Coupled with the abnormal elimination of low production performance, no estrus, and suffering from reproductive disorders, the elimination rate is even higher, which significantly increases the cost of breeding. Feed additives are It is an effective way to enhance the farrowing ability of breeding pigs, but currently there are very few feed additives on the market that specifically improve the farrowing ability of sows, and they are expensive and contain a large amount of antibiotics, which bring great potential harm to breeding pigs
