Embodiment 1

[0007] Embodiment 1: A Chinese herbal medicine feed additive for improving the anti-stress ability of pigs according to the present invention is evenly added to the rations of weaned piglets, growing pigs and finishing pigs in an amount of 1%.

Embodiment 2

[0008] Embodiment 2: A kind of Chinese herbal medicine feed additive of the present invention improves pig's anti-stress ability, has the following characteristics:

[0009] (1) Adding Ligustrum lucidum to the diet significantly increased the average daily gain and average daily feed intake of weaned piglets aged 28-56 days.

[0010] (2) Adding Ligustrum lucidum significantly reduced the content of TG in the serum of growing pigs and the contents of TG and CHOL in the serum of finishing pigs, indicating that Ligustrum lucidum can improve the lipid metabolism in pigs to a certain extent.

[0011] (3) Adding Ligustrum lucidum can significantly increase the activities of SOD and GSH-PX in serum and some tissues of pigs at various growth stages, reduce the content of MDA, and enhance the antioxidant capacity of the body, and the effect is better than that of the antibiotic group.

[0012] (4) Ligustrum lucidum has significant antibacterial effect on Escherichia coli and Salmonella...

Abstract

The invention provides a method for preparing Chinese medicinal herb feed additive having the characteristics of low price, simple production and use, small adding amount, obvious adding effect, no adverse reaction and the like and capable of improving stress resistance of pigs. The method for preparing the Chinese medicinal herb feed additive for improving the stress resistance of the pigs comprises the following steps of: crushing glossy privet fruits with a sieve of 60 meshes, then drying the glossy privet fruits at the temperature of between 50 DEG C, and uniformly adding 1 percent of glossy privet fruits into feed of weaning piglets, growing pigs and fattening pigs. The method can improve the growing speed of the pigs to a certain degree, improve the in vivo lipid metabolism, improve the oxidation resistant function in the pig bodies and improve the quality of pork, and can be applied to pig raising production practices by partially substituting antibiotics (colistine sulfate), so the method has certain practice significance for modernized research and further development of substituting for the antibiotic feed additive.

Description

(1) Technical field [0001] The invention relates to animal science, in particular to a preparation method of a Chinese herbal medicine feed additive for improving the anti-stress ability of pigs. (2) Background technology [0002] For a long time, antibiotic preparations have been used as feed additives in livestock and poultry production, and have achieved expected results. However, the long-term use of antibiotics has brought many negative effects, such as drug residues, microbial resistance, destruction of micro-ecological balance, and reduced immunity of the body. Therefore, looking for natural, pollution-free green additives has become the focus of animal husbandry researchers' efforts in recent years. The tonic Chinese herbal medicine can enhance the immune function of animals, improve the quality of animal products, antibacterial and growth promotion, and has a wide range of sources, low price, safety and convenience, no toxic side effects, low residue, and no drug r...
