Feeding pigs with high quality forage can reduce feed cost

Introduction: raising pigs with high quality forage can not only reduce the cost of feed, but also improve the lean meat rate of pork, and greatly improve the economic benefits of pig raising The high-quality forages for pig breeding mainly include grain amaranth, Russian feed vegetable, Ixeris, winter 70 ryegrass, chicory, alfalfa, white clover, etc Pig (7kg-20kg) stage: to fully supply some high-quality and nutritious piglet compound feed, based on the principle of satiety, the protein content in the feed should be more than 18%, and the Ca content should be 0.8% - 0.99% At the same time, feed a small amount of fresh and tender grass leaves properly, remember not to feed too much, the daily feeding amount should be 1kg-2kg, not more than 3kg, generally Feed fresh grass half an hour before feeding Medium pig (20kg-60kg): this stage is the most critical period to increase lean meat rate, and also an important period to save fine fodder and reduce the cost of pig raising through high-quality forage At this time, the concentrate with high protein content can be fed less, while the deficiency of protein and calcium content in the concentrate can be supplemented by adding high-quality forage, and vitamins and minerals can be supplemented, generally The daily feeding amount is 4 kg-6 kg fresh grass or high quality grass powder accounting for 15% of the concentrate (concentrate preparation: 70% corn, 20% bran, 10% concentrated feed or bean cake) The daily feeding amount of concentrate is 1kg-1.25kg Fresh grass is usually fed half an hour before concentrate feeding, twice a day The ability of digesting and utilizing crude fiber is enhanced, the resistance and adaptability are greatly improved, and the speed of gaining weight is fast At this time, corn and bran are 80% and 20% of the concentrate There is no need to add any concentrate 6kg-8kg forage or 20% of the concentrate is fed every day The concentrate is fed 1.5kg-2kg every day Fresh grass is fed half an hour before the concentrate, twice a day In the first half of the first half month, the fresh grass of 2kg-3kg, 90% corn and 10% bran mixture of 2.1kg were fed every day Empty stage of sows: if sows are too thin, more concentrate should be added Generally, sows are fed with 0.5kg-1kg concentrate, 8kg-10kg fresh grass or 20% - 30% corn + 10% bran and 60% - 70% hay powder After 80 days of gestation, the utilization rate of various nutrients in feed is high, and the growth and development of embryo is slow at this time, which is the best time to save concentrate The feeding method is the same as that of empty stage From the 80th day of pregnancy to the 35th day of farrowing, the energy and protein should be properly increased in the feed, and the calcium should be supplemented 20g bone meal or 50g fish meal should be added every day At the same time, the concentrate should be increased from 0.5kg-1kg/day to 1kg-1.5kg/day, and the high quality forage should be adjusted to 5kg-6kg / day In the lactation stage, the feed quantity of concentrate should be increased and calcium should be supplemented properly Generally, concentrate of concentrate should be 60% corn + 30% bran + 10% sow feed or 50% corn + 30% bran + 18% soybean cake + 2% bone meal The concentrate should be 2.5kg-3kg/day and 8kg-10kg fresh grass should be added The forage for pigs generally does not need to be chopped or pulped, but can be fed directly But some forages, such as chuanyesong vanilla and sweet clover, have poor palatability They can be chopped or pulped and mixed into the concentrate for feeding.
