Fast pig raising

The fast pig raising method is the scientific pig raising method and can be summed up in the following aspects: (1) The development of an economic hybrid pig crossbreeding is an important means for improving the economic efficiency of the pig industry. In many countries with relatively advanced animal husbandry, 90% of commercial pork is produced using hybrid pigs. Cross-breeding pigs have a fast growth rate. For example, the crossbreeding between the Barkshire pigs and Guangxi local pigs increases the birth weight of the crossbred piglets by 40.4-49%. The 8-week-old body weight increases by 31.3-46.6%. The growth in the medium-term is especially rapid, and it is 85% higher than that of the local pigs. . When the Yorkshire pigs were crossed with Rongchang and Neijiang pigs and the hybrid pigs weighed about 90 kg, the number of breeding days was 43-44 days shorter than that of the local pigs. Neijiang pigs and Beijing pigs and Shanxi Taigu pigs have received significant results. Economic hybrids generally have a good hybridization effect between domestic and foreign breeds. Crossbreeding between domestic northern breeds and southern breeds can also achieve good results. However, it cannot be considered that there must be advantages as long as they are hybrids. There is a problem of selection of hybrid combinations. (2) Supply of feed according to the nutritional needs of the pig In order for the pig to grow rapidly, the feed must contain sufficient nutrients. China's "Feeding Standard for Pigs" proposes the content of various nutrients per kilogram of feed when producing finishing pigs, including energy, protein, various amino acids, minerals and vitamins. The digestive energy was 3.1 megacalories, and the crude protein was different depending on the body weight. The weight of 20-35 kg was 16%, the weight of 36-60 kg was 14%, and the weight of 60-90 kg was 13%. In the preparation of pig feed must be based on feeding standards, combined with the local feed situation, a reasonable match. (3) scientific feeding: 1 feed should be properly processed and adjusted: roughage and fine feed to smash as well, beans, cottonseed cake, rapeseed cake to be cooked, the general fine material is best fed. Juicy green feed can be chopped, beaten, silaged, or fed whole, but it is best not to cook. (2) Regular ration: Feeding pigs should provide a certain number of times, a certain amount of time and a certain amount each day so that pigs can develop good living habits. The piglets were fed 6 times a day. The finishing pigs were fed 4 times a day. The interval between feedings should be equal. The feeding amount should be balanced and should not be full or insufficient. 3 advocate dry and wet method: in many places in China used to thin feed, excessive water in the feed, will reduce the secretion of digestive juice, accelerate gastric emptying, reduce the digestibility of nutrients, while also consuming more heat energy. Dry and wet feeding is based on a proportional modulation of feed and water. When the hand is tight, there is water in the fingers without drip. Dry and wet feeding can enhance the chewing performance of the pigs, promote the secretion of digestive juices, prolong the stay of the feed in the stomach, and increase the digestibility. With dry and wet methods, the pigs should supply water in time after eating. 4 Feed the concentrate first, then feed the green material: Add less concentrate to the ground, feed 3 times per meal, and do not leave it. When pigs do not want to eat, they should be given appropriate green fodder to save both food and nutrition. (4) Rational use of feed additives Feed additives include amino acids, vitamins, trace elements, and antibacterial and antiparasitic drugs that can supplement the ingredients that are lacking in feed. Some ingredients have the effect of promoting growth and can increase daily gain by 20%. (5) Careful management of temperature, humidity and light has a direct impact on the growth and development of feedstuffs and feed remuneration. Keep warm in winter. Block pigsty gaps and prepare grass. In summer, it is important to take precautions against the heatstroke, cool down the baths, and use the pergolas. The finishing pigs are best kept in quieter environments. Have enough slots to prevent snatching so that each pig can eat. Pay attention to disease prevention. To establish a disease prevention system, drowning water must be boiled before the pigs are fed, and the epidemic prevention and quarantine work is done to prevent the occurrence of infectious diseases. Regular insecticides, commonly used trichlorfon, 0.5-0.8 grams per 10 kilograms of body weight, but sometimes toxic reactions. Levamisole can also be used, 7.5 mg/kg body weight. Two months after the first deworming, another deworming was performed. The above points must not be neglected.
