Scientific pig raising new technology

The purpose of raising pigs is to obtain meat products. To raise pigs, feed and its nutrition are the material basis, the life activities of pigs are inseparable from the support of nutrients. Therefore, the level of feed nutrition directly affects the economic benefits of raising pigs.

The method for adjusting the nutritional level of pig feed is as follows:

First, adjust the nutritional level as the use (type) of the pig is different

Boars, sows, growing pigs have different nutritional needs because of different production purposes. Therefore, when the feed is formulated, the nutrition level of the feed formulation should be adjusted according to the nutritional characteristics of various pigs, so as to meet the needs of different types of pigs and different stages of growth and development, but also to save feed ingredients and reduce the cost of feeding.

Second, according to the different gender of the pig to adjust the nutritional level

Due to the different sexes of pigs, their needs for nutrients are also different. Therefore, it is necessary to adjust the level of feed nutrition according to the gender of the pigs.

Third, adjust the nutritional level with age

Piglets that are reserved for breeding become a reserve pig from the time of weaning to initial allocation. This phase is a stage in which pigs grow faster. Before and after 6 months of age, gilts should control their weight, not too much fat, and increase the amount of green roughage. Growth and finishing pigs of lean type have different growth priorities in different rearing stages and have different needs for nutrients. Therefore, it is necessary to adjust the level of dietary nutrition as the age changes.

Fourth, adjust the nutritional level as the weight changes

The different nutritional levels required before and after 60 kg of gilts, as well as the staged rearing of growing and finishing pigs, all indicate that the adjustment of the nutritional level is required as the weight of pigs varies.
