Compound feed capable of improving immunity of piglets

Abstract

The invention provides compound feed capable of improving the immunity of piglets and relates to the field of livestock culture, and in particular relates to the compound feed capable of improving theimmunity of the piglets. The invention provides the compound feed capable of reducing the diarrhea rate of the piglets and improving the immunity of the piglets. The compound feed is prepared from the following components in parts by mass: 60 to 65 parts of corn, 18 to 38 parts of soybean meal, 2 to 8 parts of fish meal, 0.3 to 0.5 part of table salt, 1 to 2 parts of mountain flour, 2 to 5 partsof tea leaf and 3 to 6 parts of a probiotic preparation. The tea leaf is black tea and / or dark green tea. The ratio of the black tea to the dark green tea is (1 to 3) to 1. The probiotic preparation comprises lactobacillus plantarum and streptococcus lactis; the ratio of the L. plantarum to the S. lactis is (5 to 8) to 1. The L. plantarum is L. plantarum P-8. The ratio of the L. plantarum to the S. lactis is 6 to 1. According to the compound feed provided by the invention, the taste of the feed is more sweeter and more beneficial bacteria good for the intestine health of the piglets also can be generated, the diarrhea rate of the piglets is reduced and the immunity of the piglets is improved, so that the survival rate of the piglets is improved and the income of farmers is improved.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a compound feed for improving piglet immunity. Background technique [0002] At present, the pig industry has become an important industry related to the national economy and the people's livelihood, and piglet breeding is the key in pig production. Factors such as nutrition, physiology, environment, and pathogenic microorganisms can cause the imbalance of intestinal microbial flora in piglets, leading to dysfunction, indigestion, diarrhea, growth inhibition, and death. According to statistics, the average mortality rate of piglets caused by diarrhea is 12%. Every year, more than 20 million piglets die due to diarrhea, causing direct economic losses of more than 10 billion yuan. In the current production practice, it is urgent to take effective measures to improve the intestinal development of piglets, maintain and give full play to the intestinal function, improve the disease...

Problems solved by technology

[0003] At present, for large-scale pig farms, no matter whether the piglets are weaned at 21 days or 28 days, the weaning process will bring a series of stress to piglets (environmental stress, digestive physiological stress, feed stress), and the piglets’ adoption The food intake drops sharply, the intestinal structure changes sharply, the ability to digest and absorb feed decreases, the overall immune level and disease resistance of the body are low, and large-scale diarrhea is prone to occur, which seriously affects the daily weight gain within one week after weaning

At present, the main conventional means of anti-diarrhea and growth-promoting diets at this stage are high copper + high zinc + high antibiotics, especially high zinc is an indispensable anti-diarrhea control method. This kind of weaning diet preparation mode not only causes environmental pollution Great pollution, and prone to growth retardation and pale complexion, long hair and curly hair in the later stage
