Application of Ligustrum Lucidum in Pure Natural Plant Feed Additives

Ligustrum lucidum, angiosperms, dicotyledonous plants, twisted flower order, family Mulleinaceae, genus Ligustrum. Growing in the mountains and fields, more planted in the garden, it has lower blood sugar and blood lipids, anti-osteoporosis, immune regulation, slow aging and many other pharmacological effects. In China, it is distributed in East China, South China, Southwest and Central China, mainly produced in Zhejiang, Jiangsu, Hunan, Fujian, Guangxi, Jiangxi and Sichuan and other places.

The application of Ligustrum lucidum in pure natural plant feed additives shows in the following areas.

1. Enhance Milk Production

Xuefen Lao et al. studied the effects of selenium-enriched Ligustrum lucidum on goat production performance, hematology and serum biochemical indicators, the results show that selenium-enriched Ligustrum lucidum, ordinary Ligustrum lucidum that added to the diet, can play a role in enhancing the goat milk production , and the selenium-enriched Ligustrum lucidum has the best effect with the addition of 10 g/d. Zhao Xiaowei et al. studied the effects of supplemental Ligustrum lucidum on the production performance and blood biochemical indexes of lactating cows, and the results showed that supplemental Ligustrum lucidum had a certain degree of enhancement on milk production of cows.

2. Improve Immune Function

Antibody plays a vital role in the regulation of immune function in broiler and laying hens. Li Qundao et al. studied the effects of Ligustrum lucidum, schizandra and oligosaccharide on the production performance and immune function of broiler chickens, and the results showed that the ND antibody potency of broiler chickens could be enhanced by the addition of Ligustrum lucidum. Lisha Shi et al. showed that Ligustrum lucidum played a positive role in the growth and development and immune function of laying hens during the breeding period, so that played a positive role in the immune function. In addition, Wang Jiali et al. investigated the effect of adding Ligustrum lucidum CO2 supercritical extract to diets on the immune performance of pigs, and the results showed that Ligustrum lucidum CO2 supercritical extract (LLE) had a certain degree of improvement on the immune performance of pigs. Yucai Chou et al. studied the effects of compound Ligustrum lucidum and probiotics on the weight gain and immune function of newborn dairy calves.

3. Improve Daily Weight Gain

Daily weight gain of broiler is a very important index for farmers. Research results show that Ligustrum lucidum extract has a tendency to enhance the average daily weight gain of broilers. Liu Jia et al. studied the effect of adding Ligustrum lucidum powder to feed on the production performance and immune function of AA broilers, and concluded that the daily weight gain of broilers in the later period would be significantly enhanced after being directly added with Ligustrum lucidum powder. In addition, the results of the study showed that the addition of 1% and 1.5% of chasteberry significantly increased the average daily weight gain of piglets.

4. Improve Antioxidant Ability

Selenium-enriched Ligustrum lucidum polysaccharides, proteins and oleanolic acid have a certain role in promoting the proliferative activity of peripheral blood lymphocytes in goats, and at the same time can significantly enhance their antioxidant capacity. The effect of Ligustrum lucidum on the production performance and antioxidant function of weaned piglets, the results show that Ligustrum lucidum promotes the antioxidant function of piglets and the effect on the antioxidant function is better than antibiotics. The effect of Ligustrum lucidum on muscle antioxidant capacity and GPx4 gene expression in AA broiler chickens, the results showed that the addition of 1% Ligustrum lucidum to broiler chicken diets could act as a substitute for flavomycin, and significantly improved the antioxidant capacity of broiler muscles after slaughter.

Green ecology is the mainstream of the development of today's era, Ligustrum lucidum as a pure natural plant feed additives have a very broad application prospects and popularization value. Its further research on pure natural feed additives will bring great benefits to the farming industry, ecology and the whole mankind.
