Embodiment 1

[0032] A breeding method for promoting estrus in sows, the specific method is as follows:

[0033] (1) Pig house breeding environment control: Divide the pig house into a living area and an exercise area. The living area is used for daily feeding and rest of the sows, and the exercise area is used for the activities of the sows; the temperature of the living area is controlled at 23-24°C , keep 10 hours of light every day, and the light intensity is 6 watts per square meter; plant neem trees on the periphery of the pig house;

[0034] (2) Mixed stalls and sports: Let the adult boars chase the sows in the sows' sports area, the ratio of boars and sows is 1:1, once a day, 15 minutes each time;

[0035] (3) Daily feeding: Feed sows with special feed for sows every day, divided into three meals in the morning, middle and evening. The total daily feeding amount is 3.5-4kg / head. Put special feed for sows;

[0036] The special feed for sows consists of the following raw materials i...

Abstract

The invention discloses a breeding method capable of promoting sow oestrus and belongs to the technical field of pig breeding. The breeding method comprises the following steps of (1) pigsty breeding environment control; (2) pig mixing and movement; and (3) daily feeding. Through control and setting of the sow breeding environment, motion, daily feeding and estrus promotion, the oestrus rate of sows can be effectively improved under the condition of not using a hormone drug; the oestrus rate is high, the efficiency is high, non-estrus sows can be reduced and eliminated and the cost is reduced. Meanwhile, use of theoestrus-promoting hormone drug can be greatly reduce, the residue of the hormone drug in a sow body can be reduced while the sow breeding rate and the sow productivity are improved, and a guarantee is provided for an excellent variety of the next generation of piglet. The oestrus rate of the sows bred by the breeding method reaches 100%.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a breeding method for promoting estrus of sows. Background technique [0002] China is the largest producer and consumer of pork in the world, and its pork output has been ranked first in the world for nearly 10 years. China's pork consumption accounts for 45%-51% of global consumption, and the overall growth trend is maintained. The pig breeding industry is also Flourish. [0003] In pig breeding, it generally includes the breeding of boars, sows and meat pigs. The operation of a pig farm mainly depends on the number of piglets provided by sows in a year or the number of fattening pigs in a sow every year. The sows are in normal estrus It is the key to raising sows. How to shorten the estrus cycle of sows, that is, shorten the time from weaning to estrus of sows after lactation, so as to increase the litter size of sows, is an important method to improve the economic bene...
