This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bos indicus influenced primiparous heifers (n = 300) and yearling Beefmaster heifers (n = 172) were evaluated to determine relationships between serial carcass ultrasound traits and ability to breed in short (45 to 90 d) breeding seasons. Data collected included carcass ultrasound traits: ribeye area (REA), intramuscular fat (IMF), rump fat (UFAT), ribfat, weight, and body condition score taken at yearling age, pregnancy determination, before breeding, and after the breeding season when pregnancy status was recorded. A logistic regression analysis was used to determine the influence of ultrasound traits and body condition on pregnancy status. Odds ratios suggested the likelihood of primiparous cattle rebreeding would have been increased by 93% if IMF would have averaged 3.5% instead of 2.5% as yearlings, or an increase in the average ribfat as yearlings from 0.287 to 0.387 cm would have increased the odds of rebreeding by 88%. Increased average body condition score of 6.5 rather than 5.5 at 30 days postpartum in primiparous cows was estimated to have increased rebreeding 367%. The odds of yearling Beefmaster heifers successfully breeding during a 45-day season would have been increased by 73% (year 1) or 274% (year 2) by increasing REA 6.4 to 6.5 cm^2 at a year of age. Steers were serially scanned beginning at approximately 265 kg of body weight through harvest in 56 day +/- 6 intervals. Data collected included ultrasound measurements (ribeye area (REA), 12th rib fat thickness (RibFat), percent intramuscular fat (IMF), and rump fat (UFAT)), weight, and carcass data. Days to choice was calculated for each steer based on a linear regression. The IMF deposition was quantified as quadratic from scans 1-6 and linear when cattle were on full feed. Prediction models at scans 1, 2, 3, 4, 5, and 6 yielded R-square values of 0.20, 0.25, 0.41, 0.48, 0.59, and 0.49, respectively for days to choice. Odds ratios suggested that if steers in this study had averaged 3.78% at day 0 rather than 2.78, the odds of cattle grading premium choice or greater would have been increased by 300%.

This book was released on 2005 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Two experiments were conducted in an attempt to predict age at puberty in heifers and reproductive performance in cows with real-time ultrasound as one of the principal tools. We measured backfat, ribeye area, intramuscular fat and rump fat. Other measurements used in the heifers were body weight and hip height combined with metabolic and hormonal profiles (glucose, insulin, and progesterone). Weight was a significant variable to predict onset of puberty. We did not find statistical evidence that adding the ultrasound measurements as explanatory variables to the logistical regression model will improve the fitness of the model. However that does not mean there is no relationship between ultrasound measurements and age at puberty. Rump fat (RF) at least had a tendency (r 0.167 and P = 0.128) to be a valuable tool in the model for predicting puberty. The lack of statistical evidence may be caused by the limited data set. The initial analysis conducted with the cows identified a high correlation among several of the primary predictor variables (ultrasound measurements). That analysis demonstrated the possibility of a statistically significant relationship between the probability of a successful pregnancy and the lower quip measurement. Upper Quip (UQ) could be another Intramuscular fat (IMF) measurement of value and merits further investigation. The log likelihood test value for UQ was close (P = 0.06) to being significant.

Book Synopsis Evaluation of Early Measures of Body Composition as Related to Beef Carcass Traits by : Richard Paul Maulsby

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two similarly managed trials were conducted to investigate serial ultrasound measures of body composition (longissimus muscle area (ULMA), 12th - rib fat thickness (UFAT), and percentage of intramuscular fat (UIMF)) early in the lives of feeder calves as they compared to carcass traits. Group 1 cattle were Charolais-sired by Brahman-British crossbred dams whereas Group 2 cattle were purebred Beefmaster. Both groups were fed at the same commercial feedlot (Graham Land and Cattle Co.) in Gonzales, Texas. In both data sets classifications were developed for ribeye area of Lower (less than 70.95 cm2, Middle (between 70.95 cm2 and 90.3 cm2) and Upper (over 90.3 cm2) based on a range that fit within the ribeye specifications of such branded beef programs as Certified Angus Beef and Nolan Ryan's Tender Aged Beef. Differences among ribeye area and quality grade (Choice vs. Select) categories were evaluated for ultrasound and carcass traits. As reported previously, correlations between ultrasound measures and carcass traits became larger at times closer to harvest. In both sets of cattle, there were no differences in fat thickness or intramuscular fat at the ultrasound scan sessions or in these carcass traits due to ribeye area category. The same trend for quality grade classification was not seen across both groups of cattle however. In Group 1, there were no differences in early measures of body composition between carcass quality grade classes except for ultrasound fat thickness at weaning. However, in Group 2 cattle there were differences in ultrasound fat at times 1 and 2, IMF at time 1, and ribeye area at time 2 between cattle that graded choice verses those that graded select. Correlations between ultrasound measures of REA (r of .26 to .50) and ultrasound REA and carcass REA (r of .16 to .81) appeared to be lower in Group 1 vs. Group 2 (r of .55, and .64 to 81 respectively). Results from this project imply that changes in ribeye area will not automatically result in changes of marbling and vice versa. Furthermore, these results also show that ultrasound is useful to help predict beef carcass traits, but that early measures of body composition used alone do not explain a large portion of the variation in the carcass measures and specific methods should be developed by different biological cattle types.

Book Synopsis Relationship Between Ultrasound and Carcass Measures of Charolais-cross Harvest Cattle Using Automated Computer Tracing Software by : Joshua John Worthington
Download or read book Relationship Between Ultrasound and Carcass Measures of Charolais-cross Harvest Cattle Using Automated Computer Tracing Software written by Joshua John Worthington and published by . This book was released on 2008 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yearling beef steers (n=86) representing typical Charolais-cross commercial cattle, were evaluated for body composition measures of muscle and fat deposition utilizing real-time ultrasound measurements. Target harvest date was estimated based on 12th rib fat thickness and weight (approximately 250 days on feed). Steers were harvested 35 days after being scanned with an ALOKA 500V ultrasound unit equipped with a UST-5049 transducer. Images were processed chuteside using Beef Image Analysis (BIA) automated software. Images were also saved to the computer hard drive and manually interpreted using Rib-O-Matic non-automated software. Mean scan live weight and carcass weight was 582.89 ± 36.44 kg and 380.8 ± 28.05 kg, respectively. Mean automated chuteside ultrasound fat thickness (AFTU), ribeye area (AREAU) and percent fat (A%FATU) were 0.88 ± 0.22 cm, 97.19 ± 7.45 cm2, 4.16 ± .48 %. Mean manually interpreted ultrasound fat thickness (IFTU), ribeye area (IREAU) and percent fat (I%FATU) were 0.89 ± 0.24 cm, 96.36 ± 7.45 cm2, 4.40 ± .73 %. Mean carcass measures of fat thickness (FTC), ribeye area (REAC) and percent fat (%FATC) were 1.15 ± 0.35 cm, 94.17 ± 7.45 cm2, 3.91 ± .75 %. Favorable pearson correlations between AFTU and FTC, IFTU and FTC, IREAU and REAC, A%FATU and %FATC, I%FATU and %FATC were 0.80, 0.78, 0.47, 0.59 and 0.69, respectively; whereas, the correlation between AREAU and REAC were lower and less significant at 0.22. These coefficients indicate that the relationship between manually interpreted ultrasound images and harvest carcass attributes were high and statistically significant. However, these results indicate that automated chuteside image processing was not as useful a tool in assessing ribeye levels on steers prior to harvest.
