During the rearing period of the finishing pigs, it is best to feed in two stages according to 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 mix the pigs. Full price diet. In the management of pigs: First, do a reasonable grouping, generally 10 to 20 heads per lap is appropriate, to ensure that each pig has a suitable field area (usually 0.4-0.8 square meters / head in the pre-fatation, late 0.8-1.2 Square meters/head) and keep the weight of pigs in the same lap bar evenly. The second method is to adopt the method of feeding raw material and feeding water, and drinking water separately. The powdered batch materials should be added with water before feeding according to the ratio of 1:1-1:1.5. The third is to 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 fed in three different times. The daily feed supply per pig can be quantified at 3.5% to 4.5% of the pig's body weight. In addition, the appetite of pigs is generally the highest in the evening, followed by the morning, and the weakest at noon. Therefore, the amount of feed each time during the day can be roughly distributed at 35% in the morning, 25% at noon, and 40% in the evening. China Agricultural Network Editor
