Poultry feed production enterprises pay attention to: chicken with feed testing standards revised

Chicken feed is one of the important nutritional sources of chicken farming.
China's chicken with feed testing standards have been GB /T 5916-2008 "egg-making reserve chicken, egg-making chicken, meat with chicken with feed" as the basis.
However, with the development of yellow feather broiler breeding and the continuous research and progress of chicken feed technology, GB/T 5916-2008 on chicken with feed nutrition provisions, it is clear that the development needs of the modern chicken industry has not been applied.
, especially the low utilization rate of feed caused by excess nutrients, and the increasing contradiction between nitrogen and phosphorus in poultry excreta and environmental pollution, have also prompted the state to make a determination to revise the feed standards for chickens.
After many investigations, collected the main domestic large-scale egg chicken, broiler, yellow chicken, broiler chicken with feed production enterprises feedback information, the National Standards Commission issued GB/T 5916-2020 "egg-producing chicken and broiler with feed" standards, and on April 1, 2021 officially implemented.
GB/T 5916-2020 is different from the previous version, the main proposed nutritional composition age-appropriate on-demand ratio, low-protein diet, excretion of pollutants control and other principles.
such as according to the type of chicken divided into egg chicken with feed, white feather chicken with feed, yellow feather chicken with feed, meat and eggs hybrid chicken with four kinds.
According to the different growth cycles of chickens need different nutrients are stipulated, for example, the brooding period, breeding period, egg-growing period, further such as egg-growing period and subdivided into pre-production, peak egg-growing, late-egg production and so on.
For chicken with feed detailed nutritional indicators requirements, specifically as follows: egg chicken with feed nutrients testing requirements: white feather chicken with feed testing requirements: yellow feather chicken with feed testing requirements: meat and egg hybrid chicken with testing requirements: From this, we can also see that chicken with feed testing key items are mainly crude protein, lysine, methionine, suline, coarse fiber, coarse ash, calcium, total phosphorus, sodium chloride and other indicators.
, in particular, the two indicators of crude protein and total phosphorus, GB/T 5916-2020 give the interval index requirements, not only the minimum limit is specified, the upper limit is given a reference index.
crude protein and total phosphorus are made in order to give full play to feed utilization rate, meet the growth needs of chickens, improve production performance.
these are all areas where people need to pay attention.
