We added a new feed additive (Ziyueyusheng, hereinafter referred to as “youshengsuâ€) in the diet of weaned to slaughtered pigs. The test proved that eugenics had effects on growth performance, carcass quality, and alternative antibiotics of pigs. Obvious effect. A total of 180 healthy weaned pigs with similar body weight were selected, and the male and female were divided into two groups at random, namely the experimental group and the control group, with 3 replicates in each group. The test period was 149 days, the previous test was 52 days, and the later test was 97 days. After the previous trial was completed, 17 trials were randomly selected from each replicate of the trial and control groups to continue the later trials. Four stage diets were fed according to the growth stage of the experimental pigs. The No. 1 and No. 2 materials were fed in the early stage and the No. 3 and No. 4 materials were fed in the later stage. Control group: No. 1 material plus antibiotics and drug net 100 milligrams per kilogram of the original, chlortetracycline 60 milligrams per kilogram, No. 2 material per kg of gallicycin 50 milligrams, No. 3 and No. 4 material without antibiotics and Drugs; test group: No. 1 and No. 2 materials were the same as those in the control group, and 400 grams of tocopherol was added per ton; No. 3 and No. 4 materials were the same as those in the control group, and eugenics added 250 grams per ton. From the perspective of growth performance, the feed weight ratio in the experimental group was 3.55% lower than that in the control group. The diarrhea rate and incidence rate in the experimental group were 38.43% and 45.86% lower than those in the control group. The average daily weight gain in the experimental group was higher than that in the control group. At 4.96%, the feed-to-weight ratio was reduced by 4.49% compared to the control group. From the perspective of slaughtering and carcass performance, carcass performance was observed by slaughter segmentation. The 6- to 7-thickness ribs, eye muscles and flesh color in the experimental group were better than those in the control group, and the lean meat was higher than that in the control group. The slaughter rate in the experimental group was increased by 0.4% compared with the control group. The test results showed that the addition of eugenics in pigs' pig feeds has a good mental state in the nursery phase, which can significantly improve the pig's immunity and health and reduce the incidence; it can replace antibiotics; the fattening stage can increase the daily gain and Feed intake, reduced feed-to-meat ratio; through slaughter tests, it was found that eugenics can improve flesh color and increase slaughter rate; pigs in the test group using eugenics can make more than 80 yuan per pig compared to the control group, significantly increasing the economic benefits of swine It is conducive to the export of commercial pork, thus reflecting the application value of eugenics in actual production. Therefore, we should vigorously promote the use of this "safe, efficient, environmentally friendly" new Chinese herbal Feed Additives.
Water treatment agents refer to chemicals used for water treatment. Usually referred to as chemicals used for sewage treatment. Widely used in chemical, petroleum, light industry, Daily Chemical, textile, printing and dyeing, construction, metallurgy, machinery, medicine and health, transportation, urban and rural environmental protection and other industries, the main purpose is to remove suspended solids and toxic substances in water, control the formation of scale, sludge, reduce the corrosion of water contact materials, deodorization, sterilization, decolorization, soft To stabilize water quality and desalination, so as to save water and prevent water pollution. It includes chemicals needed for cooling water and boiler water treatment, seawater desalination, membrane separation, biological treatment, flocculation and ion exchange technology. Such as corrosion inhibitors, scale inhibitors and dispersants, bactericides and algae killers, flocculants, ion exchange resins, purifiers, cleaning agents, pre-film agents and so on. The main products of water treatment agents include organic phosphorus water treatment agents, polycarboxylic acid water treatment agents, composite scale and corrosion inhibitors, bactericides and algae killers and other water treatment agents.
