Increase the slaughter rate of fattening pigs, that is, increase the pig's daily gain and shorten the fattening cycle, and exchange more pork with a small amount of feed. Combining with the practice of raising pigs in recent years, the author summarized 10 scientific feeding and management measures to increase the slaughter rate of finishing pigs. 1, make full use of heterosis. Hybrid pigs obtained from crossbreeding of different breeds have stronger viability than purebred parents. In the process of growth and finishing, they have good feeding, fast growth, strong disease resistance and short fattening cycle. A large number of trials have confirmed that using binary hybrid pigs can increase the daily weight gain by 15%-20% compared with purebred pigs, and that the three-way crossbred pigs increase about 25% over purebred pigs. At present, domestically used Changbai and Yorkshire hybrid sows, and then mated with Duroc, Pietrain or Hampshire boars to obtain the best three-way hybrid combination. 2, as early as iron. When piglets are born, they rely on breast milk and need 7 milligrams of iron per day. Piglets only receive 1 milligram of iron from breast milk. During the growth and development of piglets, iron deficiency anaemia often affects the growth rate. Therefore, early iron supplementation must be performed. Normal piglet 2-3 days of intramuscular injection of 1 ml of "ferritin", its effect is better. 3. To increase the birth weight and weaning weight of piglets. The piglets were born with a significant number of births, which indicated that the piglets had good growth and development in the fetus. During the subsequent growth process, the pigs were robust, had less illness, were well-fed, had quick weight gain, and were severely weaned. According to tests, pigs with severe weaning weights have been reduced to a fattening period of 1-2 months compared with weaned piglets under the same feeding and management conditions. 4, to provide a suitable temperature and humidity environment. The pig house must be controlled for high temperature and humidity, which will lead to a decrease in the feed intake of pigs, a decrease in daily weight gain, and it is not easy to prevent the heatstroke from cooling. If the temperature is too low, the calorie consumption will be large, the feed intake will be high, and the feed payment will be low. Therefore, the suitable temperature range of the pig house should be controlled at 20-30°C for piglets, 15-20°C for pigs, and humidity should be controlled at 50%-55%. 5, provide adequate clean drinking water. Water is an important material for pig growth and development. The amount of water consumed by pigs varies according to body weight, feed, and weather conditions. Generally, the body weight is large. The more dry the feed is, the higher the temperature is and the more water is consumed. The drinking water supplied must be sufficient and clean. 6, feeding to take "four changes." That is, the number of feedings, the time of feeding, the amount of feeding, and the feeding standards should be set, and the wet seasoning should be fed to pigs as dry powder. The number of feedings should be determined according to the pig's different growth stages. The piglets are generally fed 5-6 times daily, medium pigs 4-5 times and big pigs 3 times. The feeding time should be relatively fixed every day. The amount of feed fed should be balanced each time. Feeding standards, according to the pig's weight and growth stage, the deployment of different diet formula nutrition standards. In the past, feeds should be changed from traditional feeding of wet mixes to water, and feeding dry powders will help the digestion and absorption of pigs and improve feed utilization. 7, a reasonable breeding density. The pig's stocking density should be adjusted according to the size of the pigs and different seasons. It is generally appropriate to use 0.8-1 square meters per pig. For 3-4 months old pigs, each pig needs to account for 0.6 square meters, 4-6 months old pigs need 0.8 square meters, and 7-8 months old 1 square meter. Big pigs typically occupy 1.1-1.2 square meters per pig in the Summer and 0.9-1 square meters in the Winter. 8, the implementation of the same nest breeding. Piglets are slaughtered from birth to fattening, and the practice of breeding the same littermates is better than removing the piglets after weaning. Due to the reduction of stress stimuli, the daily gain can be increased by 7%-8%, and the fattening period can be shortened by 20-30 days. 9, the implementation of early castration. Castration can make the piglet calm and meek, increase appetite, and increase growth. The earlier the age of castration, the smaller the impact on the stress of the piglets, which is generally 20-25 days old. It is better to have the piglets that are weaned after 60 days of age, according to the trial. Weight gain 5%-6%, shorten the fattening period 15-20 days. 10. Prevent epidemic and deworming in due course. For fattening pigs, we must strictly follow scientific procedures for the prevention and treatment of swine fever, swine erysipelas, and swine pneumonia, and ensure the health of pigs and the high efficiency of swine breeding.
