Last Updated: 2024/11/05, The purpose of formulating the feeding standard is to carry out standardized feeding for pigs, that is, the diets used for feeding should be in line with the nutrition of specific pigs, and through the diet formula, pigs can be provided with nutritious full-price diets, give full play to the production potential of pigs, and improve feed utilization.

The purpose of    in formulating the feeding standard is to standardize pig feeding, that is, the diet used for feeding should conform to the nutrition of specific pig herds. Through the diet formula, pigs can be provided with nutritious full-price diets, give full play to the production potential of pigs, and improve feed utilization. The following basic principles should be followed in combination with pig diets:

   1. The dietary nutrient concentration, especially the energy concentration (kilojoules or megajoules per kilogram of digestible energy) and the ratio of energy to protein (the ratio of digestible energy to crude protein) should meet the nutritional needs of pigs. So that the diet can meet the needs of minerals, vitamins, amino acids and trace elements for pigs.

   2. The compound diet should be in accordance with the physiological characteristics of pigs. Pigs are omnivorous and have poor utilization of crude fiber, so they should not contain a large amount of fiber feed.

   3, feed volume and dry matter content should conform to the capacity of pig digestive tract. The feed intake (percentage of body weight) of pigs to air dry matter was as follows: pregnant sows 2.0 ~ 2.5, lactating pigs 3.2 ~ 4.0, breeder boars 1.5 ~ 2.0, growing and finishing pigs weighing less than 50 kg 4.4-6.5 ~ 50 kg 3.8 ~ 4.4.

   4. The diet should be composed of many kinds of feed as far as possible, so as to make all kinds of feed in the diet complement each other in nutrition, so as to improve the full price and utilization rate of the feed.

   4. The feed combination should be appropriate, that is, the amount of feed determined should not have adverse effects on the health, production performance and meat quality of pigs, and attention should be paid to improving the palatability of the diet. It is necessary to ensure the fresh texture and good quality of the feed, reduce impurities, eliminate toxic and harmful substances in the feed, and ensure the safety of pigs.

   5. Feed cost accounting should be carried out, and feed with high nutritional value and low price should be selected as far as possible, so as to reduce feeding cost and improve production and economic benefits.
