Finishing pig fine feeding management

Finishing pigs should be kept at a feed-to-meat ratio of 2.6:1, with a daily weight gain of 750 grams or more, and a fattening period of 110 days. Require that keepers are savvy and strong, select pigs to keep improving, keep intensive cultivation, and cost wisely. Through more than 20 years of pig-raising practice, the author has worked out a set of effective precision breeding techniques. First, the shed preparation. The economical and practical single-row plastic warm-shed pig house was selected to fully feed all the feeding methods. After each group was transferred, the barn houses and feed trough were completely disinfected, and they were idle for a certain period of time. Second, buy piglets. It is recommended to purchase healthy Sanyuan pigs from standardized farms in pest-free areas. After 5-7 days after entering the pig, excessive feeding is strictly forbidden. After the piglet is adapted to the environment, castration, epidemic prevention, and deworming are arranged. Orbital worms are driven by ivermectin, and ivermectin is sprayed. Third, rational grouping. Each batch of moderate size is 100-150 heads. Adhere to the "weakness does not stay strong," "Night is not together," according to the source, species, weight size rational grouping. Each lap raises 10-30 heads and each head occupies 0.8-1 square meters. Fourth, feed supply. The digestibility of diets for hybrids of foreign species and indigenous hybrids (15-60 kg body weight) was 13.5 MJ/kg and 12.5 MJ/kg respectively; crude protein was 17.5% and 15.5%; lysine was 1.03% and 0.9%. . The digestive energy of foreign hybrids and cross-breeding pigs (60 kg to sell) was 13 MJ/kg and 12 MJ/kg respectively; crude protein was 14.5% and 13.5%; lysine was 0.8% and 0.75%. The amount of feed can refer to the following formula: Weight 50 kg before, Feed amount = Weight 0.045; 50-95 kg, Feed amount = Weight 0.04. It is advisable to use an automatic chute (canister) feeding, with a non-automatic chute (tube) occupying 30-50 cm per pig. Fifth, supply clean water. The height of the nipple drinker is 35-45 cm in middle pigs and 45-55 cm in big pigs. In general, the amount of drinking water in winter is 2-3 times that of feed intake, 4 times in spring and autumn, and 5 times in summer. Six, pay attention to tune. After the pig enters the pig house, it will not leave the person within 3 days, and it will adjust in time to develop the habit of positioning at the three points of feeding, excretion and lying down as soon as possible. Seven, environmental regulation. The suitable temperature for finishing is 15-20°C and the relative humidity is 63-68%. Pay attention to ventilation, reduce the harmful gas content in the air, and provide toys such as waste tires and iron balls. Eight, health and disease prevention. Pay attention to the elimination of "four evils", cut off the spread of disease, and ensure biosecurity. Do a good job in housing hygiene, keep the pigsty clean and dry, clean it twice a day, and disinfect once a week. Regular observation of health status, mental status, feeding, lying down, excretion, and prevention of respiratory diseases, early detection and isolation of sick pigs, intravenous injection of severe illness. If the prevalence of epidemics in or around the farm, the pigs are in a sub-healthy state, the epidemic-prone season, or feeding and management conditions and sudden changes in the weather, the following medication plans are selected. In Option 1, one ton of feed is added with 600 grams of oxytetracycline powder, 2 grams of astragalus, 2 grams of Radix isatidis, 300 grams of windproof, 200 grams of licorice, and fed continuously for 12 days. In scheme 2, 800 grams of florfenicol and cytokines, 600 grams of astragalus polysaccharide powder, and 140 grams of lysozyme were added to 1 ton of feed and fed continuously for 12 days. Option 3, 1-15 weeks old medication 1, use 80% Zhiyuan net 125 g/ton + aureomycin 2 kg/ton + amoxicillin 2 kg/ton. Nine, timely slaughter. The 100-130 kg weight is good for sale. When the price is low or the selling price is low, the slaughter weight should not be too large. When the price is high or the selling price is high, the slaughter weight can be large.
