Embodiment 1

[0040] Embodiment 1, the preparation of sow feed additive

[0041] 1. Weigh 2 parts by weight of Enterococcus Faecium (the effective number of viable bacteria is 1.0×10 11 cfu / g), 3 parts by weight of lysozyme (enzyme activity is 5 million IU / g) and 95 parts by weight of starch.

[0042] 2. Take 20 parts by weight from the 95 parts by weight of starch weighed in step 1, and 2 parts by weight of Enterococcus Faecium (the effective number of viable bacteria is 1.0×10 11 cfu / g) and mix them until uniform to make Enterococcus faecium premix.

[0043] 3. Take 30 parts by weight from the 95 parts by weight of starch weighed in step 1, and mix 3 parts by weight of lysozyme weighed in step 1 therein until uniform to prepare a lysozyme premix.

[0044] 4. Mix the Enterococcus faecium premix prepared in step 2, the lysozyme premix prepared in step 3, and the remaining 45 parts by weight of starch in step 1 to prepare a feed additive for sows.

Embodiment 2

[0045] Embodiment 2, the influence of sow feed additive on the growth and health of weaned piglets

[0046] 1. Experimental animals and grouping

[0047] Select 22 binary grown-up sows that are healthy, in good body condition for 3-5 parities, and have similar delivery time (within 5 days apart), and randomly divide them into 2 treatments (control group, Add group), 11 sows per treatment. Each sow was fed in a single pen, and the supplementary group and the control group were separated by 2 pens.

Abstract

The invention discloses a sow feed additive for promoting growth and health of weaning pigs. The feed additive disclosed by the invention is prepared by mixing all substances in parts by weight: 2 parts of enterococcus faecium, 2-3 parts of lysozyme and 95-96 parts of a carrier, wherein the carrier is starch; the viable count in the enterococcus faecium is 1.0*10<11>cfu/g; the enzyme activity of the lysozyme is 5,000,000IU/g. According to the sow feed additive, probiotics and the lysozyme serving as a natural immune component of an organism are combined so as to cooperatively promote multiplication of beneficial bacteria in the intestinal tracts of sows, reduce the amount of harmful bacteria such as escherichia coli, maintain and regulate the balance of intestinal flora of the sows, increase the number of beneficial bacteria in intestinal contents and excrements, alleviate the action caused by the harmful bacteria, purify the environments in vivo and in vitro, create a good flora environment for new-born piglets and achieve the effects of increasing the weaning weights of the piglets, increasing the weights of the pigs weaned for 3 weeks and reducing the diarrhea occurrence rate. Furthermore, the formula of the feed additive does not contain medicaments, so that drug resistance and drug residues can be avoided.

Description

technical field [0001] The invention belongs to the field of animal feed and relates to a sow feed additive for promoting the growth and health of weaned piglets. Background technique [0002] Early weaning of piglets is an advanced technology commonly used in pig production at home and abroad, which can increase the reproductive rate of sows, reduce the transmission of diseases from mothers to piglets, and improve the growth performance of pigs during the growth period. However, affected by psychological, environmental and nutritional stress, early weaned piglets often suffer from "early weaned piglet syndrome", manifested as poor appetite, digestive disorders, diarrhea, growth retardation, and low feed utilization. At present, alleviating or overcoming early weaning stress syndrome of piglets is usually through feeding management measures and feeding suckling pig feed. However, in recent years, there have been more and more sow diseases, which are difficult to prevent and...
