Abstract

The invention discloses lactating sow feed which contains deep sea fish oil, organic microelements, steam fish meal and kelp powder. Accordingly, a corresponding feeding method is also disclosed. By adding the nutrient components and using different feeding modes, breeding efficiency and the breeding effect are both improved, productivity of sows can be obviously improved, the PSY level is increased from 16 to 25 or above, and the labor stage of the sows is short and is always 2.5-3.0 hours. The estrus rate of the sows is increased to 99% from 86% a week after weaning. Besides, the lactating sows fed with the feed have no constipation and soft and loose faeces phenomena, no anthony pigs have diarrhea in a delivery room, and a pen and the ground are clean. Milk of the sows is sufficient, the anthony pigs does not need creep, and creep materials are saved.

Description

technical field [0001] The invention belongs to the technical field of pig feed, in particular to a feed for lactating sows and a feeding method. Background technique [0002] my country is a big pig raising country, but not a strong pig raising country, and there is still a big gap between the production level and foreign countries. At present, the average PSY of sows in my country (the number of weaned piglets provided by a sow per year) is 15-16, while the PSY of foreign sows is more than 25. Therefore, there is still a lot of room for improvement in my country's pig industry. If the PSY level is increased from 16 to 25, based on the calculation of 40 million fertile sows in March 2015, and the number of slaughter pigs remains unchanged, about 12 million fertile sows can be reduced amount; if each sow eats about 1,000 kilograms of feed per year, 12 million tons of feed can be saved every year, which will produce greater economic and social benefits. [0003] The reason ...
