What measures are there to save materials for raising pigs?

(agricultural get Rich Network) what are the measures for raising pigs? Feed accounts for more than 75% of the cost of raising pigs, so if you want to reduce the cost of raising pigs, you must first make efforts on material saving. In the practice of raising pigs, the author has taken "four measures" to save feed and achieve the purpose of saving cost and increasing efficiency. -- purchase or prepare scientific and economical full-price feed, such as using reputable premix or concentrate, and prepare feed by yourself to reduce the cost. The preparation of feed formula should be adjusted according to pig breeds, feed intake, season, price changes of various raw materials and pig prices. For example, when the temperature is low in winter, the content of crude protein in pig feed can be reduced by about 1%; high temperature in summer leads to a decrease in feed intake, so it is necessary to increase dietary concentration, especially the level of energy and vitamins. In particular, an appropriate amount of oil must be added to the feed formula of lactating sows to ensure the full play of its production potential. -- feeding pigs with green fodder using American chicory, cross-leaf pine vanilla, alfalfa and other green fodder instead of concentrate to feed pigs, better economic benefits have been achieved. The average income per pig fed with American chicory 77.5kg and concentrate 214.5kg was 32.92 yuan more than that of the control group (57.87 yuan in the control group). The yield of American chicory per mu was 6000kg, and the cost per kg was about 0.07 yuan. The high fiber diet of Konghuai sows was beneficial to increase the litter size, the amount of grass fed to each sow could reach 3.5 kg / d, and the pigs in lactation sows, breeding boars and piglets were fed less green feed. -- using substitutes to open up cheap feed resources and self-made feed with premix can reduce the amount of fish meal and soybean meal and replace them with cottonseed meal and rapeseed meal by 4% each. Farmers raising pigs on a small scale can use abandoned chicken and duck eggshells, clam shells, snail shells, livestock and poultry bones to be burned and crushed, and deep yellow clay and coal ash are added to the diet by about 1% each to make up for the lack of trace elements. From hotels, restaurants, restaurants, unit canteens and other slops cooked to feed pigs a lot of experience, each pig daily feeding 7kg hogwash can achieve the purpose of saving money and growing quickly. -- reducing feed waste, strengthening the management of feed use process, checking and improving feed trough, reducing feed waste as far as possible; killing rats and flies, timely deworming, reducing feed waste caused by parasites in and out of pigs; paying attention to the harm of mycotoxins in feed, do not use moldy and deteriorated feed raw materials to feed pigs The piglet in poor health will not hesitate to dispose of it as soon as possible. If a piglet dies or is eliminated at birth, it will lose about 150 yuan, and if it dies midway, it will lose 200 yuan to 500 yuan.
