Production Characteristics

With the current situation of low profitability in the beef industry, producers must aim to produce beef efficiently and at minimum cost. In view of the ready availability of Holstein Friesian bull calves as a by-product of the dairy industry, the rearing and finishing of these animals offers a possible source of income to beef producers. The objective of the present study was to examine the influence of slaughter weight on feed efficiency and production characteristics of Holstein-Friesian bulls offered a cereal-based diet.

Production Characteristics

Holstein-Friesian bull calves, although bred for dairy traits, are available at low cost as a potential resource for the beef industry. Finishing of these cattle on intensive feeding regimes has become more attractive in recent years reflecting, inter alia, the reduction in cereal prices and availability of subsidy payments. However, in the future, market-driven economy, production systems must become more efficient if they are to remain viable. The objective of the present study was to evaluate the effect of slaughter weight on production characteristics of Holstein-Friesian bulls offered cereal-based diets, whilst also evaluating the effects of sexual status on performance attributes.

Carcass Conformation

The continuing trend for increased use of Holstein genetics in dairy herds has resulted in a large number of Holstein-Friesian bull calves becoming available, at low cost, as a potential resource for the beef industry. However, whilst these calves have been bred for dairy traits, which are negatively correlated to many important beef traits (e.g. carcass conformation), it is important to determine the potential yield of boned out joints from these animals, in order to facilitate an assessment of commercial carcass value. The objective of the present study was to evaluate the effect of slaughter weight on yield of boned out joints from Holstein-Friesian bulls and steers offered a cereal-based diet.

Ready Availability

Meat from Holstein-Friesian bulls, which are bred for dairy traits, is generally regarded as low quality and is usually destined for the commodity (mince) market. However, given their ready availability as a by-product from the dairy herd, it is important to determine if meat from these animals would be suited to higher-priced markets. Furthermore, meat from bulls is generally considered to be lower quality than that from steers, though there is a paucity of data comparing meat from both sources. Hence, the objective of this study was to evaluate the effect of slaughter weight on meat quality characteristics of Holstein-Friesian bulls and steers offered a cereal-based ration.

The effects of weaning date on feedlot performance and carcass characteristics of 367 bull calves weaned 1 mo apart were compared in a 2-yr study at the University of Alberta ranch at Kinsella, Alberta. The calves belonged to three distinct breed groups. Calves were weaned either on 1 Oct. or 1 Nov., at which time they averaged 157 ± 1.5 and 189 ± 1.7 d of age, respectively. After a 4-wk postweaning adjustment period, calves in each group were fed a mixed diet containing 90% concentrate and 10% hay. During the period between the two weaning dates early-weaned calves gained more (P < 0.05) than their unweaned contemporaries, while the performance of the two groups during their respective adjustment periods was similar. The late-weaned group gained 175 g d−1 more (P < 0.05) and consumed 800 g d−1 more feed (P < 0.05) during the 140-d feedlot test while feed efficiency did not differ between the two groups. Average daily rate of gain from birth to 1 Oct. had a significant influence on feedlot gain (b = 0.42). Although late-weaned calves had a higher rate of growth during the feedlot test, their early-weaned contemporaries were 14.3 kg heavier and 7 d younger at slaughter. Significant differences in gain and carcass traits were observed between the three breed groups, but the interaction between breed group and weaning date was not significant, indicating that calves of different genetic backgrounds respond similarly to the effects of age at weaning. The results indicate that under Alberta's climatic conditions and despite lower feedlot gains, weaning calves 1 mo early is a viable alternative to the customary weaning date. Key words: Beef calves, bulls, weaning date, carcass traits

Abstract Pulmonary hypertension (PH) can lead to premature mortality in fed cattle and is often called Feedlot Heart Disease (FHD). To date, pulmonary arterial pressure (PAP) has been the only indicator trait of PH that has been evaluated. The objective of this study was to evaluate relationships between heart score (using heart score as a phenotype for PH) and PAP, carcass, and feed efficiency traits in fattening Angus steers. Our hypothesis was that feed efficiency and carcass traits, along with PAP, would demonstrate a strong relationship with heart score. Feed efficiency, carcass, PAP and heart score data from 89 Black Angus steers from Colorado State University Beef Improvement Center were collected and used for this study. Evaluations were performed using a multiple linear regression model, which included heart score as a categorical fixed effect and age as a continuous fixed effect. Least Square Means, pairwise comparisons, and ANOVA tables were constructed per trait. PAP (P &lt; 0.001) showed an important relationship to heart score and average dry matter (P &lt; 0.10) intake approached importance to heart score. In general, feed efficiency and carcass traits decreased as heart score increased, but PAP was the only trait with a strong relationship to heart score (P &lt; 0.05). This led us to reject our hypothesis.

Criterion Variables

In this study, canonical correlation analysis was applied to estimate the relationship between body measurements and carcass traits of 28 male cross bred rabbits of about 12 weeks of age, reared under semi intensive system. Four body measurements, pre-slaughter weight (PSW) , body length (BL), chest circumference (CC), and ear length (EL) as predictor variable while dressing percentage ( DP) , hot carcass weight (HCW) and cold carcass weight (CCW) as criterion variables. Pre-slaughter weight and body length had significant (P<0.001) simple correlation coefficients with the carcass traits except for dressing percentage. The three canonical variate pairs ranged between .99 to .42 and only the first pair was significant (P<0.001). From the analysis pre-slaughter weight and body length can be regarded as the main factors as live measurement traits, while dressing percentage did not have pronounced effect on the emerged criterion variables.
