Birth Type

Records on 1820 Suffolk ram lambs from seven test stations were studied to determine the effect of birth type of lamb, age of dam, entry weight and prestation gain on test results at Canadian Record of Performance (ROP) Test Stations. Rams born as singles were heavier (P < 0.05) at station entry and gained more (P < 0.05) from birth to station entry (prestation gain) than rams born as twins or triplets, whereas twins and triplets were similar in this respect (P > 0.05). Weight on test and gain during adjustment period of rams born as singles, twins or triplets reflected these differences. Daily gain of rams on test was not influenced by type of birth. Age of dam did not affect entry weight, prestation gain, daily gain in the adjustment period, on-test weight or daily gain. The relationship between entry weight (EW) and average daily gain on test (ADG) was curvilinear and is described by the equation[Formula: see text]The 95% confidence limits of entry weight for maximum ADG were 16.2–39.8 kg. The relationship between prestation gain (PG) and ADG was also curvilinear[Formula: see text]The 95% confidence limits of prestation gain for maximum ADG were 0.27–0.71 kg d−1. Ram lambs with entry weights and prestation gain outside the 95% confidence limits had lower ADG. Test station results of ram lambs were not affected by birth type of lamb, age of dam, entry weights between 16 and 40 kg and prestation gains between 0.27 and 0.71 kg d−1.

Trends were determined for the performance traits of beef bulls of five breeds tested at the Saskatoon ROP bull Test Station between 1965 and 1986. Means were calculated for each year for each breed with respect to start-of-test weight, end-of-test weight, average daily gain-on-test, and adjusted 200-day weight. A significant (P < 0.05) year-of-test effect was found for each of the four traits studied for Angus; for start-of-test, end-of-test and 200-d weight for Hereford and Shorthorn; for start-of-test and end-of-test weight for Simmental; and for only start-of-test weight for Charolais. These data suggest that bulls in all five breeds were significantly heavier each year when entering the test and that all except Charolais were heavier each year when completing the test but that only the Angus breed gained weight on test at a significantly faster rate each year.

ABSTRACTRelationships between estimates of some factors affecting growth hormone (GH) and prolactin (PRL) secretion and rates of deposition of fat, protein and ash and rate of gain were investigated in Suffolk ram lambs. Factors affecting secretion were determined from measurements made by radioimmunoassay on blood samples collected at 15-min intervals during a 6-h period at a body weight of 43 to 58 kg. Depositional traits were estimated over the period of growth from 32 to 73 kg. The endocrine secretory measurements were adjusted statistically for weight at blood sampling. The only single endocrine secretory measurement that significantly correlated with a growth or depositional trait was frequency of GH peaks which was negatively related to rate of ash accretion. Multiple regression analysis was used to estimate the association between endocrine secretory measurements and rates of gain and accretion. R2 values were 0·43, 0·29, 0·42 and 0·70 for average daily gain and accretion rate of protein, fat and ash, respectively. Models with minimal error mean squares contained linear, quadratic and/or crossproduct terms for the independent variables, thus suggesting nonlinear relationships of the hormones in the mediation of rate and pattern of growth. These results emphasize the value of assay of multiple samples from each animal, the subsequent estimation of secretory characteristics and the use of expanded statistical models to determine the relationship present in the system under investigation.

Sire Breed

ABSTRACTThe distribution of lean tissue between eight standard joints was examined in 956 crossbred lambs slaughtered at constant live weights of either 35 or 40 kg. The sire breeds used were the Dorset Down, Ile-de-France, Oldenburg, Oxford, Suffolk and Texel. Sire breed did not have a significant effect on the proportion of total carcass lean found in the higher-priced joints but did show significant differences in the proportion of total carcass lean found in individual joints, with a maximum difference of 7·7 g total lean per kg joint being recorded. Similarly, small but significant effects due to ewe age (1 to 3 years), rearing type (single, twin, triplet), sex (male castrate, female) and weight of total lean were reported for the proportion of total carcass lean found in different joints.Heritability estimates ranged from 0·07 (s.e. 008) to 0·65 (s.e. 0·16) for the proportion of total lean in the best-end neck and higher-priced joints respectively. Phenotypic standard deviations of 5·8g/kg and 17·9g/kg were reported for the proportion of total lean found in the best-end neck and the higher-priced joints respectively. The genetic correlations between the proportion of total lean in each of the higher-priced joints and the proportion of total lean in the higher-priced joints combined were positive. A genetic correlation of 017 (s.e. 0·20) was found for the relationship between average daily gain from birth to slaughter and the proportion of total lean in the higher-priced joints.

Genetic parameters were estimated for 2403 purebred Yorkshire pigs over a 2-yr period, representing 21 sires. The traits studied included average daily gain, age adjusted to 90 kg, ultrasonic measurements of backfat at the mid-back and loin positions, total and adjusted total ultrasonic backfat and corresponding carcass backfat measurements. Least squares analyses were used to estimate and adjust for the effects of sex, year-season and sex by year-season interaction. Heritabilities and genetic correlations were calculated for all traits using both half- and full-sib estimates. Adjusted age and adjusted total ultrasonic backfat measurements were found to have the highest heritabilities of the live traits in this study. Estimates of heritability for adjusted age and adjusted total ultrasonic backfat were 0.24 ± 0.10 and 0.26 ± 0.10 based on half-sib and 0.56 ± 0.07 and 0.41 ± 0.06 from full-sib analyses. The genetic correlation between these two traits was −0.07 ± 0.28 based on the half-sib method. The total phenotypic correlation was −0.01 ± 0.02.

Abstract This study evaluated changes in performance of bulls enrolled in the Utah Beef Improvement Association’s (UBIA) annual performance tests conducted in accordance with central bull test standards established by the Beef Improvement Federation. Breeds with over 500 bulls enrolled over the period of 2004 to 2018 were included in the evaluation. The breeds with greater than 500 animals evaluated included the Angus, Red Angus, Hereford and Simmental Breeds. Traits evaluated included birth weight, initial weight, a 205-day adjusted weaning weight, final test weight, average daily gain, adjusted yearling weight, and weight per day of age. The mixed model procedure of SAS and interval regression analyses were utilized to evaluate the yearly rate of change for each breed and to determine if that rate of change was significantly different (P &lt; 0.05) between the evaluated breeds. When evaluating all breeds represented across years, significant differences (P &lt; 0.05) were observed for rate of change when evaluating birth weight and 205-day adjusted weaning weight. However, no differences were observed between breeds with more than 500 animals represented. Significant differences (P &lt; 0.05) for rate of change were observed when comparing the top four represented breeds, for average daily gain, initial test weight, final test weight, adjusted yearling weight and weight per day of age. Specifically, a declining trend was noted for all breeds when evaluation all significant traits. When evaluating the previously described traits, the Angus breed was significantly different in its rate of decline when compared to the Red Angus and Hereford breeds. The lone increasing trend was observed in the Hereford breed which had a positive increasing trend for initial test weight which was significantly different (P &lt; 0.05) from both the Angus and Red Angus breeds but not significantly different from the Simmental breed.

Studies were undertaken to evaluate bloodless castration (B) based on growth and carcass traits. During the first 28 d, bloodless and surgical (S) castrates showed a 51–53% and 68–73% reduction in average daily gain, respectively, compared with intact bulls (I) (P < 0.05) in two trials. Bulls grew faster than steers overall. Carcass traits and grade were similar for B, S and I (P > 0.05). Key words: Bloodless, surgical, castration, growth, carcass traits
