Mechanistically, the link between carcass length (number of vertebrae) and number of teats can be explained by results from studies in mice, revealing a role for the somites, i.e. precursor structures for vertebrae, in the induction of mammary gland development [ 22, 25, 27].
In these reserves the "carcass ratio", a number used to assess the death rates within populations, indicated elephants were dying at four times the natural rate.
Statistical analysis showed that the CA3 microsatellite polymorphism was associated with dressing percentage, internal fat rate, carcass length, rib number and backfat thickness in the pig.
There was a positive association between the proportion of heifers that had passed puberty, their carcass weight and number of days from day zero.
Seven of these nine traits i.e. birth weight, weaning weight, carcass weight, teat number, IMF, Back-Fat Thickness (BFT) between the 3rd and 4th ribs of a carcass at 6 cm from the spine and Longissimus Dorsi (LD) depth were chosen because they had been recorded in both designs with the same conditions.
Marked otoliths or fin-clip ratios from spawner carcasses estimated the number and proportion of hatchery-born spawners (Table 2), and scales were collected to age spawners as part of biological data for recovery monitoring (WDFW and PNPTC 2007).
The following data were extracted and derived from the FLEKO database for each slaughterhouse, for each animal category for each month between January 2007 and December 2012: total number of carcasses processed and number of whole carcass condemnations during normal slaughter and emergency slaughter (slaughter of sick or injured animals).
In the United States, where individual cuts are not graded, a U.S. Number 1 carcass is one having the most satisfactory ratio of fat to lean; Number 2, Number 3, and Number 4 have a higher proportion of fat, reducing the amount of lean.
