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

Embodiment

[0025] From May to June, 100 primiparous sows, 100 multiparous sows of 1-3 litters, and 100 multiparous sows of 4-6 parities (300 in total) were taken for breeding, and the mating method was natural estrus.

[0026] The raising of 300 sows of the present embodiment in the breeding period comprises back-up period raising, gestation period raising and lactation period raising;

[0027] The feeding during the backup period includes the following steps: feed sows with a body weight less than 75kg ad libitum; feed the sows at a rate of 1.5-2kg of feed per day from the day the sows weigh 75 kg to the last day before mating, Feed at this stage includes by weight percentage: 45%, wheat bran 30%, soybean 16%, soybean oil 5% and premix 5%;

[0028] The feeding during pregnancy includes as follows:

[0029] From the date of mating to 70 days of gestation, feed each pig at the rate of 2kg of gestation feed per day. During this period, from the date of mating to 30 days of gestation, if ...

Abstract

The invention discloses a breeding method for a sow in a reproduction period. The method comprises the following steps: feeding in a reserve period, feeding in a pregnancy period, and feeding in a lactation period. According to the invention, directed at actual states of the sow in all stages of the reproduction period, targeted feeding with a feed with different components and proportions is economic, scientific and reasonable, and fully meets the requirements of the sow for nutrients in all stages at the same time, so the sow can remain a good growth state from oestrum to piglet delactation, i.e., the sow in an oestrous period has the advantages of well-developed, high-quality and numerous ova, high pregnancy rate, high survival rate of fertilized ova, high survival rate of early embryos in the early stage of mating, good developmental state of metaphase embryos, and high survival rates of the piglets after birth and in the lactation period; thus, the marketing rate of commercial pigs is fundamentally increased, and pig-raising efficiency is improved.

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...
