Sow breeding method in reproduction period

Abstract

The invention discloses a sow breeding method in a reproduction period. The method includes the steps of feeding in a backup period, feeding in a gestation period and feeding in a suckling period; according to actual conditions of each stage in the reproduction period of sows, the sows are fed with fodder containing different ingredients according to different proportions in a targeted mode; the method is ecological, scientific and reasonable, nutrient demands in each stage of the sows are met completely, and therefore a great growth state of the sows can be maintained from the estrus to the weaning period of piglets; eggs of the sows in the estrus grow well and are high in quality and large in quantity, the pregnancy rate is high, the survival rate of fertilized eggs is high, the survivalrate of early embryos in the early hybridization period is high, the growth conditions of the embryos in the medium term are great, the survival rates of the piglets after birth and during the suckling period are both high, the slaughtering rate of commercial pigs is increased fundamentally, and the economic benefits of pig breeding are increased.

Description

technical field [0001] The invention relates to a method for raising poultry and livestock, in particular to a method for raising sows during the breeding period. Background technique [0002] In the intensive farming process of pigs, the feeding of sows is very important. High conception rate of sows, large litter size and high lactation survival rate are the key to improving the economic benefits of farms. In addition to being affected by pig age and environmental conditions, improper feeding will lead to overfat sows often leading to infertility after mating, and underweight sows will produce fewer mature eggs, resulting in irregular estrus; specifically, feeding before mating affects sows. The development, quality and quantity of pig eggs, the feeding of sows in the early pregnancy after mating affect the number of embryos in the early stage, and the feeding in the middle stage of mating affects the normal development of pig fetuses, which is the key to improving the su...

Problems solved by technology

Either the method is too general, or it only proposes a targeted solution for the specific situation that occurs during the feeding period, but does not form a specific systematic feeding method that can be applied to each stage of the sow's reproductive period in the process of intensive farming, so that Sows can achieve high conception rate, litter rate and lactation survival rate in the process of large-scale feeding
