A Preliminary Estimate of the Heritability of Uterine Cervical Diameter in Tropically Adapted Beef Cattle
Mean uterine cervical diameter, parity and parentage information was recorded from 246 Santa Gertrudis females in southern Queensland. A linear model was fitted to estimate the effects of parity on cervical diameter. The sire variance component was also analysed to provide an estimate of the heritability of cervical size. The effect of parity on cervical size was found to be highly significant ...
متن کاملCosts and Benefits of Beef Cattle Fattening Schemes in some Selected Areas of North West Tanzania
This study highlights the costs and benefits of indigenous beef cattle fattening schemes in Shinyanga Urban and Kishapu Districts in Tanzania. Specifically, in this study the net profit (NP) for fatteners between beef cattle fattening schemes has been determined. The schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (CSHL) based diets and ...
متن کاملRumen fermentation and liveweight gain in beef cattle treated with monensin and grazing lush forage.
OBJECTIVE To determine the prevalence of subacute rumen acidosis (SARA) in beef cattle grazing lush pasture and the effect of monensin on reducing SARA and improving animal performance. DESIGN Commercial Angus and Murray Grey steers received a monensin slow-release capsule (n = 19) or remained untreated (n = 19). Cattle grazed an oats crop or tetraploid ryegrass pasture for a total of 91 days...
متن کاملMineral Supplements for Beef Cattle
elements for normal bodily maintenance, growth, and reproduction. Minerals that are required in relatively large amounts are called major or macro elements. Those needed in small amounts are classified as micro, minor, or trace minerals. These terms, however, have no relationship to the metabolic importance of a mineral in the diet. A trace mineral can be as essential to the health and performa...
