How to reduce waste pig feed hidden
First, the scientific feeding. Present in pig production,[link widoczny dla zalogowanych], the more easily overlooked problem is the feed per kg only pay attention to the nutritional level,[link widoczny dla zalogowanych], and not pay attention to the daily diet of feeding amount. Ingredients at the same time in science, science must pay attention to feeding the feed, to its full potential weight gain and improve feed utilization. General growth of fattening pigs fed the fine feed amount of body weight by about 4% of pig feed, pigs can be in the 60 kg body weight after feeding 3.5%; also be based on expected average daily gain and feed efficiency is expected (feed / gain weight) determined that the average daily gain (kg) × feed efficiency (feed / weight gain) = day of feeding amount (kg). Second, scientific feeding. According to early growth of pig slow, medium fast, late and slow the growth pattern, in order to obtain a higher price of feed, feeding should be taken straight fattening way to shorten the breeding cycle, saving feed. At the same time, to implement fine, green, crude feed with, and implementation of mixed feeding raw tide. In the feeding times, take two meals a day to feed the system in order to reduce the number of pigs fed stimulus motion increases, thereby increasing energy consumption and the loss of Liquid feed to reduce feed efficiency. Third, the optimum temperature. Pens to be kept clean and dry, warm winter favorable, favorable summer heat for the growth of pigs to create a suitable environment to reduce the incidence of the disease, reduce the maintenance consumption,[link widoczny dla zalogowanych], improve feed utilization. Suitable temperature for the general pig 17 ~ 21 ℃, high or low feed efficiency were adversely affected. Fourth, improve disease prevention. To improve disease control and insecticide, to minimize morbidity, to improve feed utilization. In pig production, every year a considerable number of pigs suffering from chronic diseases and parasitic diseases caused by waste feed hidden. Therefore, pigs have to do a good job and regular deworming program on immunization, to ensure healthy growth of pigs to improve feed utilization. V. timely slaughter. Pigs at different growth stages, bone, lean and fat growth of varying intensity. In the growth stage (60 kg ago), rapid growth of bones and meat, feed efficiency is high; and then increase with age and body weight, fat growth than lean meat,[link widoczny dla zalogowanych], 1 kg of fat and long than the length required to feed 1 kg more than 2 times higher lean meat. Therefore, the longer the feeding period, the heavier weight, feed efficiency is lower. Suitable for general hybrid pig slaughter weight of 90 to 100 kg; cultivated varieties of Chinese pigs is 85 kilograms, less training and non-cultivated species around 75 kg. (Zhang Yuan Zhang Yuan)
