Comparative Efficacy of Beta-agonists on in Vivo Body Composition and Resting Heat Production in Growing Kids
نویسنده
چکیده
In vivo body composition and resting heat production was determined in male growing kids treated with beta agonists – clenbuterol, salbutamol and terbutaline on day-0, day-21 and day-42 of the treatment period. There was marked difference in body water and body fat percentage, however it was not significant. Resting heat production (kcal/kg 0.75 /hr) did not differ significantly between groups as well as between periods.

Transhumant production system (TPS) is a type of extensive livestock production practiced by transhumant pastoralists in which indigenous livestock breeds are mainly fed a pasture-based diet. The hypothesis tested in this work was whether differences existed between fat samples from the different species in respect to ratios of n-6/n-3, and polyunsaturated fatty acids to saturated fatty acids. ...

A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...
