While scientifically formulating the appropriate amount of ingredients, we must pay attention to the scientific feeding of feed in order to give full play to its potential for weight gain and improve the utilization of feed. Generally, the feed amount of the growing and finishing pigs' concentrates is about 4% of the pig's body weight. The lean-type pigs can be fed with 3.5% of their body weight after 60 kg. The expected daily weight gain and the expected utilization rate of the feed can also be used ( Feed/growth weight) Determined for immediate gain (kg) Feed utilization (feed/gain) = Daily feed (kg).
Suitable for feeding According to the growth and development law that the pig grows slowly in the early period, fast in the middle period, and slow in the later period, the straight breeder feeding method should be adopted to shorten the feeding period and save the feed. At the same time, we must implement fine, green, and coarse feed mixes, and implement mixed feeds.
Suitable temperature enclosures should be kept clean and dry, warm in the winter and beneficial in the summer, creating a suitable growth environment for pigs to reduce the occurrence of diseases, reduce consumption, and improve feed utilization. The suitable temperature for general pigs is 17°C-21°C. Too high or too low have adverse effects on feed utilization.
Appropriate prevention of epidemic disease prevention and control and insect repellent, to minimize the incidence rate, in order to improve the utilization of feed. In pig production, a considerable number of pigs each year suffer from the hidden waste of the disease caused by chronic diseases and parasitic diseases. For this reason, plan immunization and regular deworming can guarantee the healthy growth of pigs.
Timely slaughter in the pre-growth period (before 60 kg), bone and lean meat grow faster, feed utilization rate is high; then with the increase of age and weight, fat grows more than lean meat, and feed ratio of 1 kg fat is longer One kilogram long lean meat is more than twice as high. Therefore, the longer the feeding period and the heavier the weight, the lower the feed utilization rate. The suitable slaughter weight for general hybrid pigs is between 90 kg and 100 kg.
