Problems solved by technology

However, since the virus is not sensitive to antibiotics and antibacterial drugs, the simple use of antibiotics will not only be ineffective but will increase the damage to the digestive tract and cause raw milk loss
The main function of most Chinese herbal medicine products is to stop diarrhea and improve cold resistance, but the effect is slow and unstable, and cannot effectively solve the problem

Embodiment 1

[0022] The premix components are: 300 parts of active biological factor antimicrobial peptide, 400 parts of yeast culture, 2 parts of vitamin A and 5 parts of vitamin E as immune enhancer, and 293 parts of endotoxin adsorbent aluminosilicate.

[0023] In the experiment, 100 dairy cows were selected and randomly divided into two groups according to the principle of similar milk production and parity to evaluate the health status of the premixed dairy cows when winter scour occurred. They were fed loosely and had free drinking water. The results showed that the premix exhibited a good preventive effect, as shown in Table 1 below.

[0024] Table 1. Effects of premix on the health of mature milk cows (winter dysentery occurs)

[0025] group

Embodiment 2

[0027] Premix components: 400 parts of active biological factor antimicrobial peptide, 400 parts of yeast culture, 3 parts of immune enhancer vitamin A, 2 parts of vitamin E, 195 parts of endotoxin adsorbent aluminosilicate.

[0028] In the experiment, 80 dairy cows were selected from a pasture, and randomly divided into two groups according to the principle of close milk production and parity to evaluate the effect of the premix on the milk production of dairy cows with winter dysentery. The test period is 90 days. The results showed that the premix exhibited a good preventive effect, as shown in Table 2 below.

[0030]

Embodiment 3

[0032] Premix components: 500 parts of active biological factor antimicrobial peptide, 200 parts of yeast culture, 1 part of immune enhancer vitamin A, 10 parts of vitamin E, 289 parts of endotoxin adsorbent aluminosilicate.

[0033] The experiment selected 60 dairy cows from a pasture, and randomly divided them into two groups according to the principle of close milk production and parity to evaluate the effect of the premix on the milk production of healthy milk. They were raised in a loose manner and allowed to drink water freely. The test period was 60 days. sky. The results showed that the premix exhibited a good preventive effect, as shown in Table 3 below.

[0035]

[0036] To sum up: in each embodiment, the test group has shown better application effect.

Abstract

The invention relates to a premix for preventing winter scour of dairy cows. The premix includes 200-500 parts of active biological factor, 200-400 parts of yeast culture, 2-15 parts of immune enhancer vitamin, and 100 parts of endotoxin adsorbent ‑300 servings. The invention can increase the anti-viral toxin function of dairy cows, improve the immune function and anti-oxidation function of the body, greatly relieve the clinical symptoms of winter scour of dairy cows, reduce the damage to production performance and health status of dairy cows, improve the recovery ability of the body, and have a certain effect on winter scour of dairy cows. Good preventive effect.

Description

technical field [0001] The invention belongs to the field of dairy cow premix, in particular to a premix for preventing winter scour of dairy cows. Background technique [0002] Winter dysentery in dairy cows is an acute, highly contagious disease, especially in barn-feeding dairy cows, because it occurs from November to March of the following year, and the clinical features are mainly severe watery diarrhea (sometimes containing mucus and Blood), so called winter dysentery (Winter Dysentery), milk production sharply decreased (25-95%), accompanied by dehydration, depression, loss of appetite and mild respiratory symptoms such as cough and other performances. The incidence of the disease is very high. In a lactating herd, 20-50% of the cows may develop the disease within 3 days at the same time, and almost 100% of the lactating cows will develop the disease in about 1-2 weeks. It is a severe disease in many countries in the world during the cold season. One of the most impo...
