Compound feed for first-born nursing sow

Abstract

The invention relates to a compound feed for a first-born nursing sow, and aims to effectively solve the problems of poor reproductive performance, poor body condition and influence on the reproductive performance of first-born sows. The technical scheme for solving the problems is that: the feed is prepared from maize or puffed maize, wheat or puffed wheat, bean pulp, mountain flour, calcium hydrogen phosphate, common salt, carrier-containing nursing sow complex vitamin, carrier-containing nursing sow complex mineral and auxiliary materials, wherein one kilogram of feed comprises 50 to 650 grams of maize, puffed maize or a mixture thereof, 50 to 650 grams wheat, puffed wheat or a mixture thereof, 100 to 300 grams of bean pulp, 8 to 18 grams of mountain flour, 10 to 28 grams of calcium hydrogen phosphate, 3 to 6 grams of common salt, 8 to 12 grams of carrier-containing nursing sow complex vitamin, 8 to 12 grams of carrier-containing nursing sow complex mineral and the auxiliary materials. The feed can completely meet the requirement of the first-born sow for suckling pigs on nutrition and ensure fast weight gaining of the suckling pigs during the nursing and high survival rate so as to improve the annual sell rate of a pig farm, increase the survival rate and increase the total sell rate of each sow throughout the life.

Description

1. Technical field [0001] The invention relates to a feed, in particular to a compound feed for first litter lactating sows. 2. Background technology [0002] The existing compound feed for lactating sows is suitable for all parity sows during lactation. The nutritional standard is designed according to the needs of multiparous sows. However, since the weight of first-parity sows is still growing and their reproductive organs are still developing, Therefore, the nutritional requirements are different from those of multiparous sows. Feeding first-parity lactating sows with compound feed during the lactation period of ordinary sows will lead to excessive weight loss during lactation, and the low re-estrus rate within one week after weaning, so it is always used Short life span; low birth weight and weaning weight of piglets, high mortality rate, poor reproductive performance of first litter sows, low body condition affects sows' lifetime reproductive performance, thus affecti...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a compound feed for first-parity lactating sows, which can effectively solve the problem of breeding of first-parity sows. Poor performance, low body condition, and affecting the reproductive performance of sows throughout their lives. The technical solution is to combine corn or puffed corn, wheat or puffed wheat, soybean meal, stone powder, calcium hydrogen phosphate, salt, and lactating sows with carriers. It is made of multi-dimensional, carrier-containing compound multi-mineral and auxiliary materials for lactating sows, and its weight ratio is 50-650g / kg of corn or puffed corn or the mixture of the two, 50-650g / kg of wheat or puffed wheat or the mixture of the two, soybean meal 100-300g / kg, stone powder 8-18g / kg, calcium hydrogen phosphate 10-28g / kg, salt 3-6g / kg, carrier-containing lactating sow compound multidimensional 8-12g / kg, carrier-containing lactating sow compound multi-mineral 8-12g / kg and auxiliary materials;
