GB/T 10647 Terminology of Feed Industry
3 Terms and definitions
The following terms and definitions defined in GB/T 10647 apply to this document:
3:1
Nutrient requirements
Minimum nutrient requirements
The minimum amount of nutrients an animal needs to maintain normal physiological activities, body health, and achieve specific production performance:
3:2
Lean-type pig
Pigs whose carcass lean meat percentage is at least 55:0% when their live weight reaches 95kg~105kg before slaughter:
Note: The carcass lean meat rate is generally obtained by the slaughter measurement method specified in NY/T 825:
3:3
Fatty pig lard-typepig
When the live weight before slaughter reaches 70kg~95kg, the carcass lean rate is lower than 45:0% of pigs:
Note 1: The lean carcass rate is generally obtained by the slaughter determination method specified in NY/T 825:
Note 2: Most local pig breeds and hybrid pig breeds in my country are fat pigs:
3:4
Meat-type pig
Pigs whose carcass lean meat rate is between 45:0% and 55:0% when live weight reaches 85kg-100kg before slaughter:
Note: The carcass lean meat rate is generally obtained by the slaughter measurement method specified in NY/T 825:
