Embodiment 1

[0031] Embodiment 1, the feed that does not contain sugar beet meal

[0032] The feed consists of 53wt% corn (cp7.5), 15wt% wheat, 12.5wt% soybean meal (cp43), 2wt% fishmeal (cp66), 8wt% peeled expanded soybeans, 5wt% wheat bran and 4.5wt% premix composition.

Embodiment 2

[0033] Embodiment 2, the feed (beet meal content 5wt%) that improves the production performance of lactating sows according to the present invention

[0034]The feed for improving the production performance of lactating sows according to the present invention consists of 5wt% sugar beet meal, 51wt% corn (cp7.5), 15wt% wheat, 12.6wt% soybean meal (cp43), 2wt% fish meal (cp66), 8wt% Composition of dehulled expanded soybeans, 2.2 wt% wheat bran and 4.2 wt% premix.

Abstract

The invention belongs to the technical field of feeds, and discloses a feed capable of improving the productive performance of lactating sows and a feeding method thereof. The feed comprises 5wt%-10wt% of beet pulp. The beet pulp is added into the feed, so as to reduce the cost of feed, increase the level of digestible fiber in feed, and improve the productive performance of lactating sows. Experiments show that: feeding the sows with the feed according to the feeding method can effectively improve the productive performance of lactating sows, obviously increase the average daily feed intake of lactating sows, simultaneously increase the average weaning weight of piglets, the piglet weight at weaning, the average daily gain of piglets and the daily lactation yield of lactating sows, shorten the interval between ablactation and oestrus of lactating sows, and increase the oestrus rate in 10 days after ablactation.

Description

technical field [0001] The invention relates to the field of animal science, in particular to a feed and a feeding method for improving the production performance of lactating sows. Background technique [0002] One of the most important links in pig breeding is the breeding of suckling piglets, and to raise suckling piglets well, pregnant sows must be raised well. Sows are the main force of pig farms. Improving the reproductive performance of sows is the goal of pig farms. The performance of sows determines the profit of pig farms. Pigs are multiparous animals, and the number of litters per litter is generally about 12. The weight of piglets has increased by more than 4 times within one month from birth to weaning. The number of sucklings and rapid weight gain of piglets means that most of the nutritional sources are provided by sow milk. It is estimated that the lactation performance per unit weight of sows is much higher than that of high-yielding dairy cows. When the f...
