First, the application in the pig industry
Herbal additives can increase the appetite of pigs and increase pig weight gain and feed utilization.
Chen Jincai et al reported that adding 5% of hawthorn powder to the finishing pig diet, the daily gain of fattening pigs increased by 15.6%, and the feed remuneration increased by 4.4%.
The results of experiments conducted by Li Wenbin and others showed that 0.2% of the compound of Codonopsis pilosula, Atractylodes, Astragalus, Angelica, Chuanxiong, Bupleurum, Xiangfu, Musk, Baiqi, Licorice and other Chinese herbal medicines were added to the commercial pig diet. The Chinese herbal medicine additive increased the daily weight gain of the test pig by 24.10% and the feed conversion rate by 19.49%.
Li Siyuan et al reported that the experimental pigs were divided into 4 groups. Groups 1 and 2 were supplemented with 1% and 0.5% compound Chinese herbal medicine additive 1 (composed of Polygonum, Malt, Pine Needle Powder, and Tangerine) in the basal diet, and Groups 3 and 4 were based. 1% and 0.5% compound Chinese herbal medicine additive 2 (composed of pine needle powder, cypress seed, hawthorn and mirabilite) were added to the diet. The results showed that the daily weight gain of pigs in groups 1-4 was 15.39%, 9.25%, 14.65% and 8.97% higher than that of the control group, respectively, and the feed conversion ratio increased by 2.9%, 2.1%, 4.5% and 3.3%, respectively.
Jinling Mei et al pointed out that in the summer high temperature, Chinese herbal medicine additives consisting of 13 Chinese herbal medicines such as hawthorn, atractylodes, tangerine peel, betel nut, astragalus, and koji were added to the commercial pig diet (the amount of 20-40 kg piglets added was 1.0%, 40~60kg of pigs added 0.5%), which can alleviate the effect of heat stress on the performance of commercial pigs. The test pigs gained 8.7% weight, the feed utilization rate increased by 12.4%, and the feed cost per kilogram of weight gain decreased by 8.3. %.
Wang Wei used Chinese herbal preparation BMSL (composed of Croton, Hegan, Shouwu, etc.) to feed 40- to 50-day-old Duchangda ternary hybrid pigs. The amount of addition was: test group I 1 BMSL/head, test group II 2 BMSL/head, test period 125 days. The results showed that the daily weight gain of group I and II increased by 12.02% and 10.26%, respectively, and the feed utilization rate increased by 7.41% and 7.69%, respectively.
Zhao Lianyu et al reported that 1% of Chinese herbal medicine additives consisting of Shouwu, Shenqu, Malt, Atractylodes, Angelica, Chenpi, Hawthorn, and Alfalfa were added to the diet of Changbai pig. The average daily weight gain of the test pigs was 20.9% higher than that of the control group. Conversion rate increased by 3.32%.
Zhang Shuxian's research showed that 1% of Chinese herbal medicine additives consisting of hawthorn, atractylodes, radix isatidis, ginger, malt, huangjing, mantle, dried tangerine peel, pulsatilla, garlic, etc. were added to the diet of weaned piglets. Compared with the control group, the average piglets in the experimental group were compared. The daily gain increased by 33.02%, the feed-to-meat ratio decreased by 17.44%, and the economic benefit increased by 41.31%.
Zhu Longsheng and other test results showed that 1% piglet Zhilingling (composed of 15 Chinese herbal medicines such as hawthorn, Liuqu, Pulsatilla, and gentian) was added to the piglet diet. The average pig litter weight was 24.13% higher than that of the control group. The weight gain increased by an average of 22.58%, the survival rate increased significantly, reaching 97%, no diarrhea and other diseases; adding 1% sow stimulating spirit in the sow diet (from Astragalus, Angelica, Motherwort, Wang Buliu, etc.) The composition of 12 Chinese herbal medicines increased the average lactation rate of the test pigs by 16.64% compared with the control group, the average weight of piglets increased by 16.38%, the daily weight gain of piglets increased by 17.32%, the survival rate of piglets reached 97.85%, and no diseases such as diarrhea occurred. In the growing pig diet, 1% of the growth pigs were added to Changling (from 12 Chinese herbal medicines such as Astragalus, Radix Paeoniae Alba, Polygonum multiflorum, and Guanzhong). The average daily weight gain of the test pigs was 16.95% higher than that of the control group, and the feed conversion rate was increased by 15.20. %.
Meng Zhaoju added 1% of the scutellaria powder to the piglet diet, which increased the daily weight gain of the test pig by 23.6%, the feed conversion rate by 13.3%, and the economic benefit by 41%.
