I N connection with the record of performance work carried out at the U.S.D.A. Research Center, Beltsville, Maryland, various body measurements of each steer were taken at a live weight of approximately 900 pounds. This work was undertaken to determine whether any association existed between body measurements and the slaughter grade, carcass grade, and dressing percentage of the steers. If such...

Real-time ultrasound measurements (Falco 100 device, linear probe 3.5 MHz) were used to estimate in vivo carcass composition of Hungarian Merino (n=9) and British Milksheep (n=10) ram-lambs. Animals aged 110-120 days and were growing 29.73+/-1.11 kg and 28.98+/--0.95 kg, resp. There were little between-breed differences in the ultrasound records for subcutaneous fat thickness (0.33+/-0.10 cm; 0...

B ODY conformation in cattle is one of the important bases in judging and selecting animals for breeding and production purposes. Measurements taken on various parts of the body furnish an objective description of body conformation. The ability of cattle to produce meat could be estimated with these measurements if relationships between body measurements and meat production characters were obta...

The most widely used system to predict percentage of retail product from the four primal cuts of beef is USDA yield grade. The purpose of this study was to determine whether routine ultrasound measurements and additional rump measurements could be used in place of the carcass measurements used in the USDA yield grade equation to more accurately predict the percentage of saleable product from th...

Department of Animal Science,Faculty of Agriculture,University of Uyo, Uyo, Akwa Ibom State, Nigeria A total of 40 New Zealand white rabbits were used in a study where prediction models were developed for predicting live weight and evaluating the carcass. In the study, six body measurements namely, body length, thigh circumference, shank length, chest width, body circumference and girth were de...

The objective of this study was to evaluate the genetic response for a divergent selection experiment on intramuscular fat (IMF) content and to estimate the correlated response in carcass and meat quality traits. Data from two generation of selection were used in this study. The base population was composed of 13 males and 83 females. High (H) and Low (L) lines had 8 males and approximately 40 ...

A joint growth-carcass model using random regression was used to estimate the (co)variance components of beef cattle body weights and carcass quality traits and correlations between them. During a four-year period (1994-1997) of the Australian "southern crossbreeding project", mature Hereford cows (N = 581) were mated to 97 sires of Jersey, Wagyu, Angus, Hereford, South Devon, Limousin, and Bel...

Carcass evaluation has a relatively long history in the animal and meat science scientific literature and one of the first studies to cover the composition of farm animals was reported by Lawes and Gilbert (1860) almost 130 years ago. These workers completed a large number of chemical analyses and found a relationship between fat and maturity (age and weight); a finding that has been repeated b...
