MSY: The number of fat pigs per sow per year. MSY=PSY× survival rate of finishing pigs.
PSY: refers to the number of weaned piglets that each sow can provide each year, which is an important index to measure the benefit of pig farms and the reproductive performance of sows. PSY= annual litter size of sows × average litter size of sows × survival rate of suckling piglets.
RSY: The annual return on investment of single sow refers to the data model of sow productivity and benefit after all production costs are locked, which is the core and essence of pig farm production and management.
What do PSY, MSY, LFY and RSY stand for in pig farms -: 1, LFY: the number of litters per sow per year (fetal index). 2. MSY: The number of fattening pigs per sow per year. MSY=PSY* Survival rate of finishing pigs. 3. PSY: refers to the number of weaned piglets per sow every year. It is an important index to measure the benefit of pig farm and the reproductive performance of sow. PSY= annual parity of sows * average litter size of sows * survival rate of suckling piglets. 4.RSY: The annual return on investment of single sow refers to the data model of sow's productivity and benefit after all production costs are locked, which is the core and essence of pig farm production and management. The main factors affecting PSY in pig farms are: 1, parity; 2. Genetic factors; 3. Ovulation rate and embryo mortality rate; 4. Nutritional factors; 5. Breeding management; 6. Wild boar effect; 7. Management level; 8. Reproductive diseases. Reference source: Sogou Encyclopedia-Pig Farm
Excuse me, what does blood biochemical GGP mean? -:One of blood biochemistry, glutamyl transpeptidase. The reference value is: γ -glutamyl transpeptidase (GGT) U/L 0-50 Results Analysis γ -glutamyl transpeptidase (GGT): GGT mainly comes from the hepatobiliary system, so it is mainly a monitoring item of hepatobiliary diseases. (1) Liver inflammation: GGT increased slightly and moderately. (2) Other hepatobiliary diseases: liver cancer, hepatic obstructive jaundice, biliary cirrhosis, cholangitis, gallbladder polyps, gallstones, pancreatitis, pancreatic head cancer, biliary tract cancer, etc. GGT has obviously increased. (3) Long-term or heavy drinking will also lead to the increase of this enzyme.
What does PIGREN mean-:pig farmers, pig farm management!
