Although the addition of antibiotics to feed can promote the growth of animals, long-term use can cause harmful residues in animal products, making bacteria resistant in animals. Ziyue eugenics is a high-quality Chinese herbal medicine perilla that has been used for more than 2,000 years in China. It uses supercritical CO2 fluid extraction technology to completely extract all active ingredients and is purified, activated and stabilized. Made. The product is rich in active substances such as α-linolenic acid, linoleic acid and flavonoids. Alpha-linolenic acid and linoleic acid can regulate animal physiological metabolism and enhance disease resistance through a series of metabolic conversion products (such as PGE3, PGE2, PGE1, DHA, EPA, etc.). Flavonoids have strong physiological activity in animals, can significantly promote animal growth, reduce fat deposition, improve reproductive performance, remove oxidative free radicals in the body, and have strong antioxidant capacity. In this experiment, the effect and feasibility of using purple moon eugenics to replace the antibacterial feed additive in pig diet were investigated by adding purple moon eutrophic acid instead of antibiotics in the weaning-listed commercial pig diet. Materials and methods A total of 80 healthy Du × Chang × large hybrid weaned piglets with an initial body weight of about 10 kg were selected and weighed and randomly divided into two groups of 40 heads each. Two replicates per group, 20 replicates each. Feeding trials are divided into two phases: pre-test period and positive trial period. The pre-test period is 7 days (April 1, 2011 to April 7, 2011), and the trial period is 103 days (April 8, 2011 to July 19, 2011). This test was carried out at a farm in Hunan Province. The test diet design is shown in the table below. Group 1 basal diet + antibacterials; Group 2 basal diet + Ziyue eugenics, Ziyu eugenics added 200 grams per ton full price feed. Ziyue Yusheng is provided by Chongqing Yousheng Technology Development Co., Ltd. Results and analysis Disease and physical appearance The test pigs were sick: 7 patients in the antibacterial group were sick, the incidence rate was 17.5%; 5 in the eugenics group were sick, and the incidence rate was 12.5%. It indicated that Ziyue eugenics can replace the antibacterial feed additive used in pig diet and reduce the incidence. The physical appearance of the test pigs: the eugenics group had smooth hair, ruddy skin and good uniformity; the antibacterial group had better physical appearance than the eugenics group. Production performance The daily weight gain of the eugenics group was 8.81% higher than that of the antibacterial group, and the ratio of feed to meat was 10.69%. It is indicated that the addition of Ziyue eugenics to pig diet can effectively promote pig growth and increase feed conversion rate. Slaughter performance and carcass quality The euphorbia group had a 6.55% lower backfat thickness than the antibacterial group, 11.71% more than the antibacterial group, 4.17% of the slaughter rate, 6.48% of the carcass lean rate, 9.49% of the water rate, and an increase in the eye muscle area. 6.57%. It can be seen that the addition of Ziyue eugenics to pig diet can effectively improve the slaughter performance, carcass quality and commercial value of pork. Serum Metabolism Index Serum growth hormone (GH) in the eugenics group increased by 23.91%, the content of triiodothyronine (T3) increased by 26.47%, and the content of tetraiodothyronine (T4) increased by 14.34%. The content of INS) increased by 25.23%, and the urea nitrogen content of eugenics group was 10.75% lower than that of antibacterial drug group. These changes in serum metabolic indicators indicate that pigs with added purple eutrophic acid have enhanced metabolic capacity and increased growth rate. Serum immune index The serum IgG content of eugenics group was increased by 6.17%, the serum IgA content was increased by 14.20%, and the interleukin-2 content was increased by 14.29%. The elevated levels of these immune indicators indicate that Ziyukyusheng can effectively improve the immune function and disease resistance of animals. The data of this experiment indicated that: Ziyue eugenics can improve the immune function of growth and finishing pigs and reduce the incidence rate. The effect of preventing diseases is better than that of antibiotics; the growth performance of growth and finishing pigs is better, and the effect is better than that of antibiotics; The endocrine level of pigs is grown and fattened to promote metabolism; the slaughter performance and carcass quality of growing and finishing pigs are improved; and the physical appearance of pigs in growth and finishing pigs is improved.
