Growing and finishing pigs are the fastest growing stages in a pig's life. During the pig raising stage, feed costs account for 60% to 80% of production costs. The main reason for this is that during the finishing phase, it is necessary to obtain a proper profit. The efficiency at this stage is very important. , can start from the following aspects.
1, choose a good pig. Crossbreeding between different breeds and utilizing heterosis are effective measures to increase the productivity of growing and finishing pigs. Secondly, we must select piglets that are severe in the corporal body and should be bred to open the ribs and have large breasts. The piglets with thick and thick bones should be selected. The eyes should be bright and sleek, and the pigs that are actively grazing should be fattened.
2. Appropriate dietary nutrient levels are important for the effect of pig fattening on energy and protein. Within certain limits, the more energy is eaten, the faster the weight gain and the higher the feed utilization.
3. According to the growth and development characteristics of pigs, it is possible to adopt the “high-height, low-low†rearing method: Before the weight of 60kg, use high-energy, high-protein diets, after the weight of 60kg, appropriately reduce the energy and protein levels, limiting the intake .
4, must provide adequate fat drinking pigs, if not enough water, it will lead to loss of appetite, so that pigs grow slower.
5, develop a reasonable immunization program, do a good job vaccination work. Each head should be vaccinated to avoid omissions and prevent epidemics.
6, do a good job deworming. Deworming is usually carried out for the first time at the age of 90 days, and a second deworming is carried out when necessary around 135 days of age. Aphids are commonly used to repel aphids. They use 20 mg per kilogram of body weight and are fed once in the feed.
7. The pig house must be clean and dry, fresh air, and regularly sterilized. In the cold winter, if you want to reduce the speed of the air flow, the light in the fattening barn can be dim, as long as it is convenient for the pigs to eat, so that the pigs can get enough rest.
8, to timely slaughter, fat weight increased to a certain weight, the weight gain rate will be slower, feed utilization decreased, depending on the situation, timely slaughter, in order to achieve the best breeding economic benefits.
