Abstract

The invention belongs to the technical field of pig feeding management, and discloses a feeding management method for improving production performance of ternary sows, which remarkably improves the production performance of the ternary sows and increases the breeding benefits of fattening pigs as breeding pigs. The method mainly comprises the following five steps: step 1, a feeding management method in the reserve period; step 2, a feeding management method in the early stage of pregnancy; step 3, a feeding management method in the middle stage of pregnancy; step 4, a feeding management method in the late period of pregnancy; and step 5, a feeding management method from the lactation period to the post-weaning oestrus. By adopting the technical scheme to feed the ternary sows, the three breeding problems that the ternary sows have small number of piglets and insufficient milk and are not obvious in oestrus can be effectively solved, and the ternary sows can produce 3-4 healthy piglets per birth on average.

Description

technical field

[0001] The invention relates to the technical field of pig feeding and management, in particular to a feeding and management method for improving the production performance of triple sows. Background technique

[0002] The price of breeding pigs has repeatedly hit record highs. A large number of farmers plan to resume production but it is difficult to find breeding pigs. No matter what kind of pigs, as long as they are sows, they are kept for breeding. Pigs are used as breeding. Since ternary commercial pigs are used for meat rather than for breeding, they are raised according to conventional original sows and binary sows. They have the characteristics of fast growth, low birth, insufficient milk, and inconspicuous estrus, which lead to breeding The production efficiency is extremely low. It is imminent to seek a feeding management method to improve the production performance of three-element sows. Contents of the invention

[0003] In view of the above-...

Examples

Embodiment 1

[0078] A feeding management method for improving the production performance of three-element sows, comprising the following steps:

[0079] (1) Breed selection and rearing of gilts:

[0080] Breed selection: Select 100-120 day old ternary sow breeding pigs with good health, as long as possible, belly, strong physique and single coat color.

[0081] Feeding of gilts: 110 days old, the immunization program of gilts is carried out, and the feed of gilts is fed with silage; among them, 1.8kg of feed for gilts per day is added to the feed of gilts, and 2wt% of silage;

[0082] When the sow's body weight reaches 130-140kg, the third mating is carried out; wherein, one week before the mating, 1wt% electrolytic multidimensional is added to the gilt feed, and an additional 20g of fish meal is added to each sow every day;

[0083] (2) Pre-pregnancy sow feeding:

[0084] Breeding - 28 days of pregnancy: within two days after mating, each sow is fed with 1.8kg pregnant sow feed every d...
