This patent uses common pre-pregnancy feed, post-pregnancy feed, and breastfeeding feed to feed sows before pregnancy, after pregnancy, and during breastfeeding. The nutrient requirements of each stage of the plant are refined, which may lead to unsatisfactory nutrient supply throughout the production cycle

Embodiment 1
[0028] The present embodiment provides a kind of method that improves feed intake of lactating sows during lactation, comprising the following steps:
[0029] (1) After the weight of gilts is greater than or equal to 75kg, each pig is fed with 2.2-2.5kg of special feed for gilts every day;
[0030] (2) Start aphrodisiac 10 days before mating, and each pig is fed 3-3.5kg of special feed for lactating sows every day. If the pig has one litter, it needs to reach a weight of more than 120kg and an age of more than 220 days, P 2 The backfat thickness of the point should be above 18mm;
[0031] (3) From mating to 3 days of pregnancy, feed pregnant sows special feed. Among them, if sows have 1 to 2 parities, the daily feed intake of each head should be less than 1.8kg, and it should be controlled at about 1.5kg. For sows with more than 3 litters, the daily feed intake per head is about 1.8kg. In the first 3 days of pregnancy, high feed intake can easily lead to increased embryo mor...

The invention relates to a method for improving the feed intake of lactating sows during the lactation period. The method includes eight stages; starting from the sow reserve stage, the scale of feeding and the types of feeds are controlled until self-help feeding of the sows 10 days after delivery, and the self-help feed intake of each sow reaches about 6.0 kg / day. According the method, targetedfeeding is started from the sow reserve stage until 10 days after the delivery of the sows, during the period, eight-stage targeted feeding is conducted, different nutrition requirements for the wholeproduction period of the sows are more detailed, finally, it is ensured that the sows have sufficient feed intake and have no excessive weight loss during the lactation period, and the service life period of the sows is greatly prolonged. According to the method, the sows are fed with different feeds at different stages before hybridization, the sows are fed with a special reserved sow feed in the early stage, and 10 days before hybridization, the sows start to be spurred into estrusm and are fed with a special lactational sow feed; compared with an existing method that the sows are fed witha feed used before pregnancy all the time before hybridization, more comprehensive nutrition can be provided for the sows, and the nutrition requirements of the sows before pregnancy are met.
Description
technical field [0001] The invention relates to the field of animal and feed nutrition, in particular to a method for increasing feed intake of lactating sows during lactation. Background technique [0002] In pig production, the low feed intake of sows during lactation and the shortening of sow life due to excessive weight loss are common problems in recent years and have always affected the pig industry. [0003] With the continuous development of modern genetics and breeding science, sows are characterized by reduced fat tissue, increased mature body weight, early sexual maturity and higher feed conversion rate. Limits the maximum performance of the sow's reproductive performance: reduced feed intake, insufficient lactation of the sow. [0004] Due to the insufficient feed intake of sows during lactation and the large number of litters, in order to meet the needs of lactation, sows adjust themselves to decompose body fat to meet the energy needs of mammary glands, so sow...
