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%.

Download or read book Evaluation of Early Measures of Body Composition as Related to Beef Carcass Traits written by Richard Paul Maulsby and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: "Livestock production systems will only be sustained in the long term if their products continue to meet the demand of consumers. The quality of ruminant carcasses, meat and meat products is of predominant importance in a competitive market where consumers tend to have a preconceived idea about the criteria that define meat quality such as flavour, tenderness, juiciness, smell, colour and texture. The carcass evaluation could be interesting as a precocious classification of the final quality of meat coming from each carcass. Today the quality characteristics of the meat must be different according to its utilisation (supermarket, butcher, catering, refectory, etc.) and so it is very important to choose very early the final destination of the carcass. Obviously, the carcass classification must correlate with meat quality characteristics required by final consumer. Other important factors that have to be taken into account in order to maintain a demand for ruminant meat are safety and traceability. This book reviews the historical and recent developments for carcass evaluation and grading for meat quality assessment in beef and sheep. It places special emphasis on new concepts and approaches to define carcass and meat quality and on the use of modern technologies for composition and quality evaluation. A range of technologies are presented such as ultrasounds and colour reflectance, X-ray computerised tomography, spectral and thermal imaging, image analysis and NIRS. The use of phenotypic markers such as the plasma hormones and genetic markers to predict carcass composition and meat quality are also presented."

Download or read book The Use of Ultrasound Body Composition Measurements to Track Puberty in Heifers and to Predict the Reproductive Ability of Mature Beef Cows written by Mercedes Marambio and published by . 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.

Download or read book Evaluation of Ultrasound and Other Sources of Information to Predict Beef Carcass Traits and Final Carcass Value written by Dustin Tyler Dean and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Purebred Beefmaster steers (n = 160) from five owners were fed at a commercial feedlot in South Texas beginning in November of 2004; 68 steers possessed pedigree information. Beginning in mid-November, steers were individually weighed and evaluated for ultrasound body composition at 56-d intervals by a certified technician. Feeder calf frame (FRM) and muscle (MUS) scores were assigned at initial ultrasound evaluation. Steers were fed and marketed through a lean-based, branded beef programand were harvested in two groups in May and June of 2005 at a commercial beef plant. Analyses were conducted to investigate the ability to predict carcass traits from the different sources of information available on these cattle. Evaluation of carcass traits were investigated using four sets of independent variables referred to as sources A, B, C, or D and ultrasound scan session (1- 4). An analysis included initial weight at first scan session (IWT), FRM and MUS as independent variables through GLM procedures. B analyses utilized ultrasound measures of the longissimus area, intramuscular fat, fat thickness, rump fat, and gluteus medius depth along with IWT as independent variables. Multiple regression was performed on each carcass trait using IWT and ultrasound traits at each scan session. Mallow's CP was used to select a model that best described each carcass trait. C analyses (GLM) utilized variables from A and B analyses combined plus ranch. D analyses (GLM) included variables from C analyses plus sire nested within ranch. Respective R-square values (scan 1 - 4) for marbling score were .02, .04, .05, and. 10 using A information, .14, .17, .42, and .54, using B information, .35, .35, .47, and .55 using C information, and .56, .59, .65, and .76 using D information. R-square values ranged from .34 to .86 for carcass weight, .11 to .77 for fat thickness, .06 to .82 for ribeye area, and .10 to .81 for yield grade. Ultrasound data obtained closer to harvest and increasing amount of data related to genetic and management background showed increased R-square values, but may be best utilized in conjunction with one another to predict carcass traits and final carcass value.
