The predictability of performance factors and costs affecting the cost of gain of fed cattle in Texas feedyards
(1992)
Data including actual measures and estimates of various performance and cost factors were collected from three commercial feedyards located in the Texas Panhandle. The effectiveness with which such performance and cost ...
Non-invasive, objective measurement of intramuscular fat in beef through ultrasonic A-mode and frequency analysis
(1991)
A noninvasive, objective measurement method for predicting intramuscular fat concentration in beef through ultrasonic A-mode and frequency analysis was developed. Ultrasonic longitudinal and shear speed were evaluated for ...
Heritabilities and phenotypic and genetic correlations for bovine postrigor calpastatin activity and measures of meat tenderness and muscle growth
(1992)
The objectives of the present study were 1) to determine the heritability (h^2) of bovine postrigor calpastatin activity and the phenotypic (r[p]) and genetic (r[g]) correlation coefficients between bovine postrigor ...
Some physical aspects of digestion of forages by steers : and binding of ytterbium and hafnium as digesta particle markers
(1987)
Ingestive and ruminative chewing, meal and dorsal rumen contractions were measured in yearling beef steers offered foraged diets based on either Coastal bermudagrass [Cynodon dactylon (L.) Pers] or sorghum X sudan [Sorghum ...
Investigation of the mechanisms that influence the accretion of bovine intramuscular and subcutaneous adipose tissue
(1987)
The understanding of the mechanisms that differ between breeds of cattle and their ability to deposit intramuscular adipose tissue is imperative to profitable beef production. Thus, the interactions among breeds, metabolic ...
Parameters to describe the growth of male cattle
(1987)
Parameters were estimated for nonlinear growth curves for bulls of five straightbred and 20 crossbred breedtypes produced in two generations of a diallel. The primary intent of this study was to use the estimates obtained ...
Fenprostalene-induced luteal regression in the beef cow : histological and ultrastructural characterization
(1987)
Brahman-cross cows (day 11 or 12 of the estrous cycle) were used to study the effects of prostaglandin-induced luteolysis on the corpus luteum (CL). Four cows (0 h controls) were injected (sc) with saline while 16 cows ...
Trace mineral interaction on reproductive performance of beef cattle under range conditions in Edwards and McCulloch Counties, Texas
(1989)
In Exp. I the effects of mineral supplementation on reproductive performance of Brangus-type cows grazing native range was monitored by tissue (serum and liver) parameters, body condition score (BCS) and days to conception ...
Serum and milk mineral concentration and milk yield of beef cows of three breed types
(1992)
Sixteen Hereford x Holstein (HH), 25 Hereford x Jersey and 27 Hereford (H) cows 7 to 12 yr of age grazed native and improved pastures as a single group in two experiments. Cows were mated to one of two Charolais bulls over ...
Effects of age, breed and method of carcass suspension on Bullock beef palatability, carcass traits, histological measurements and certain age and yield predictors
(1976)
The effects of slaughter age, breed group and method of carcass suspension upon certain carcass characteristics, histological measurements and palatability traits of bullock beef were assessed by use of a sample of 115 ...
