to measure an unbiased farm-specific efficiency of individual dairy farmers, a shadow-price profit frontier adjusted for market distortion was applied to a sample of 860 iranian small intensive dairy farms surveyed in 2005-2006. this measure was then compared with that of unadjusted measure that assumes undistorted market. a multiple general linear model (glm) technique was applied to the data ...

Data on body weight of pure-bred kittens (Maine Coon, Norwegian Forest Cat, Birman, Persian, Siamese/Oriental Shorthair Cat) from birth (n 245) to 12 weeks of age (n 135) were obtained from breeders. Absolute birth weight (in g) was higher in larger breeds than in smaller breeds, whereas relative birth weight (in % of mature female weight) tended to be higher in smaller breeds (Maine Coon 115 g...

We present the calculation of Next-to-Leading-Order Quantum Chromo Dynamics corrections for the production of a W or Z weak boson associated with a bottom anti-bottom quark pair at hadron colliders (pp̄, pp → W/Z bb̄), including the effects of a non-zero bottomquark mass. We find a considerable reduction of the renormalization and factorization scale dependence of our results with respect to Lead...

The role indigenous livestock can play in Africa’s Livestock Revolution is not always recognized. In many parts of Africa pure breeding with indigenous breeds is the only viable production strategy because of adverse climatic and nutritional conditions. However, there are scenarios where the higher demands of exotic breeds and their cross-breds can be met. This article discusses the possibility...

This report presents the results of chromosome analysis of blastocysts collected and processed as previously described (McFeely, 1966) from seven gilts selected at random from the swine herd at the University of Pennsylvania. No records of parentage of the gilts were available, but as they consisted of various breeds and cross breeds from a variety of sources, it was assumed that they were not ...

this study was carried out by using two hundred ewes (2-4 years old) as  pure breeding (zel × zel) and crossbreeding (chal × zel). in each treatment, 30 male and 30 female lambs were fattened in a feedlot experiment for three periods; 75, 100 and 125 days. at the end of each period, 10 lambs of each treatment were slaughter and carcasses analysis was down. the lean meat percentage and bone perc...
