The phrase "age at slaughter" is correct and usable in written English.
It can be used in contexts related to agriculture, animal husbandry, or food production, specifically when discussing the age of animals when they are processed for meat.
Example: "The study focused on the impact of diet on the age at slaughter of cattle, aiming to improve meat quality."
Alternatives: "slaughter age" or "age of slaughter."
Age at slaughter: 50 days.
Age at slaughter: 40 days, though 37 is possible.
Fifteen gilts DB-90 (DanBred) were divided into three groups according to gestational age at slaughter (50, 80, and 106 days).
Consequently, age at slaughter was greater in lambs raised by ewes receiving hay post-partum compared to grazing ewes (36 days vs. 32 days, P < 0.05).
The department should mandate the use of rapid tests, currently used in Europe, which have allowed testing of all cattle above a certain age at slaughter.
Effects of year-month of slaughter, age at slaughter, sex and breed were statistically significant, and herd accounted for about 20 57% of the total variation in the data.
The phenotypes were pre-corrected for the effect of sex, litter, season and different age at slaughtering before QTL analysis.
Estimated breeding values for BFT were calculated in the population using a BLUP-Multiple Trait-Animal Model that included the fixed effect of sex (considering the triplets of pigs from the same litter), batch on trial, inbreeding coefficient of the animal, interaction of sex by age at slaughtering, date of slaughtering and random effect of litter and animal.
This result confirms that swine remains susceptible to HEV infection at any age, even at slaughter, that in Italy normally involves animals of 9 months of age and more.
However, this mechanism can not apply to the time period we are studying here (from 2001 onwards), during which all cattle over 30 months of age were tested at slaughter, as well as all animals over 24 months of age sent for emergency slaughter or for rendering.
In addition to the risks associated with crowding, animals of commercial operations may constitute a higher risk for human infection when their relatively young age at time of slaughter does not suffice for developing immunity to common farm pathogens.
