Embodiment Construction

[0045] The present invention will be described in further detail below in combination with specific embodiments.

[0046] The invention relates to a method for raising fattening pigs. The fattening pigs are offspring sows produced by crossing Huainan black sows×large York boars, and offsprings produced by crossing Duroc boars.

[0047] The fattening pig consists of three feeding periods, which are the piglet period, the nursery pig period, and the fattening pig period. Among them, the piglet period is 0-14 days, eating sow milk; the nursery period is 15 days-2 months, feeding special piglet feed; the fattening period is 3-10 months old, a total of 8 months, feeding the fattening period feed.

[0048] (1) The 8-month fattening period is divided into two stages:

[0049] 1) During the 4-month growth period between 3-6 months of age, the growth rate is fast, and the feed is fed in the early stage. Each pig is fed a total of 259 kg. The feed in the early stage is:

[0050] Corn...

Abstract

The invention discloses a rearing method for fattening pigs. The fattening pigs are reared in two stages, and separately fed with different kinds of feed regularly and quantitatively, it is ensured that balanced nutrition is provided for the pigs, the growth speed of the pigs is increased, the feed conversion ratio can be improved, the health conditions of pig bodies can be improved, and the immunity of the pig bodies can be improved; moreover, the stall-feed fattening pigs are effectively prevented from developing symptoms of wilting, constipation, inappetence and the like, weight gain of thefattening pigs is effectively promoted, significant improvement of the meat-production rate and the meat quality index is promoted, the pork is high in water-holding capacity and succulence, brightlyred in color and luster and good in texture and taste, and the pork quality and flavor are improved; besides, the carcasses are good in quality, the eye muscle area is large, the quality and the commodity value of the pork are remarkably improved, the feed-gain ratio is reduced, and the rearing method has very good economic benefits.

Description

technical field [0001] The invention relates to the technical field of fattening pig breeding, in particular to a method for raising fattening pigs. Background technique [0002] Since pigs were domesticated by humans, their meat products have played a pivotal role in human food consumption, providing humans with high-quality protein. Pork is currently the most consumed meat product in the world, accounting for 37% of the world's total meat consumption. So far, countries around the world have made great progress in the genetic improvement of pigs, especially in growth and carcass traits such as growth rate and lean meat percentage. The progress of the diet, and the nutritional level, feeding method and feed quality of the diet directly affect the growth rate, feed utilization efficiency and carcass quality of the finishing pigs. [0003] At present, the commonly used feeding methods include "straight line fattening" and "open front and rear limit". [0004] The so-called s...
