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 ...
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 ...
Involvement of the endogenous opioid peptides in suckling-induced inhibition of LH release
(1991)
Two studies were conducted to further understand the involvement of the endogenous opioid peptides (EOPs) in suckling-induced inhibition of LH release. Experiment A in the first study was designed to evaluate the effect ...
