Here are some key issues in the autumn pig raising.
1. Autumn pigs need heavy pig management
During the rearing of finishing pigs in the fall, it is best to raise in two stages according to the body weight (25-60 kg in the pre-fattening period and 60-100 kg in the later period). According to the nutritional needs of the pig, select the local feed resources and use the concentrated premix to feed the pigs. With the full price diet. In terms of herd management: First, do a reasonable grouping, usually 10-20 pigs per lap is appropriate, to ensure that each pig has a suitable field area (usually 0.4-0.8 square meters / head in the early fattening period, the latter 0.8-1.2 Square meters/head) and keep the weight of pigs in the same lap bar evenly. The second is to do a good job of the "three-point positioning" of the pigs, so that the pigs from the beginning to develop a fixed place defecation, feeding and sleeping habits.
2. Fall pigs need to prevent disease
In autumn, pigs are most susceptible to swine fever, flu, Eperythrozoonosis, and Streptococcus suis disease. In this season, it is particularly important to prevent and treat these diseases. Strengthen live pig rearing and management, prevent wind, cold, and wet invasion, increase ventilation and ventilation, timely remove excreta, sludge, muddy water in the circle, keep the ground dry, clean, thicken bedding, keep warm, prevent acne , is the focus of the autumn pig breeding work.
3. Autumn pigs should pay attention to feeding management
In the autumn when raising pigs, in addition to strengthening the conventional feed management, but also do a good job of pig feed reserves and fattening fattening work. In the fall, sweet potato, Chinese yam, peanut pods, bean stalks and other comminuted fermentations are all good pig feeds. Potato tubers, legume pods, etc. can be dried and crushed to feed the pigs.
In the feeding method, adopt the method of raw material wet feeding, drinking water alone, powdered batch materials, and add water before feeding according to the ratio of 1:1-1:1.5. Establish a regular and quantitative feeding system. In order to promote digestion and improve feed utilization and growth rate, the daily diet of finishing pigs can be divided into 3 times. In addition, the appetite of pigs is generally the highest in the evening, followed by morning and the weakest at noon. Therefore, each day of the The amount of feed can be roughly distributed in the proportion of 35% in the morning, 25% in the midday and 40% in the evening.
