Embodiment Construction

[0010] (1) Estrus polyovulation technology

[0011] High ovulation should start from the three stages of gilts, lactating sows and empty pregnant sows.

[0012] 1. Methods to improve PSY of gilts

[0013] (1) Time of first mating: 220-230 days old;

[0014] (2) The weight of the first mating: 130-140 kg;

[0015] (3) Breeding during the second or third estrus;

[0016] (4) It is best to mate while contacting an adult boar;

[0017] (5) Supplementary feeding technology for reserve pigs:

[0018] ① When the back-up pigs are raised to 95-100 kg, control the feed intake to 85% of the ad libitum intake for 25-30 days;

[0019] ②When the weight reaches 115-120 kg, change to free feeding until estrus and mating, the time is 10-14 days;

[0020] Solution: Increase the content of calcium and phosphorus in the feed to 15%;

[0021] (6) Daily feeding amount: 2.5-4 kg;

[0022] (7) Nutritional requirements for gilts:

[0023] ① Feed digestibility is 13-13.5MJ / kg, protein content ...

Abstract

The invention provides a sow high-yield technology which is applied to the technical field of pig cultivation. According to the technical scheme, sow oestrus and much ovulation are promoted, fetal death is reduced, breastfeeding milk quality is increased, and meanwhile sow health protection is paid attention. The sow high-yield technology is characterized by comprising an oestrus and much ovulation technology, a mating and much nidation technology, a pregnancy and miscarriage proof technology, a delivery and stillbirth-free technology, a breastfeeding and lactation disorder proof technology and a sow drug medicine protection technology. The technical scheme in cultivation is given out systematically, the cultivation is programmed and digital, the sow pregnancy rate and the farrowing number are increased, the sow service life is prolonged, and production costs are reduced.

Description

technical field [0001] Animal husbandry, pig farming technology. Background technique [0002] The core of the pig farm is the sow, and the core of the sow is the annual productivity (PSY, the average number of weaned piglets provided by each sow per year). Ten years ago, 1 sow in a foreign country produced 20-24 weaned piglets per year; now, sows in top Danish farms can get 30 weaned piglets per year. In 2009, a pig farm in Beijing provided an average of 15.5 qualified pigs per sow per year. The low annual productivity of sows has become a bottleneck restricting the production and development of the pig industry. [0003] The previous technical solutions only paid one-sided attention to a certain reproductive stage of sows; single selection of a certain drug may easily cause sows to develop drug resistance. The invention patent links and comprehensively pays attention to different reproductive stages in the reproductive cycle of sows and different nutritional requirement...
