the optimum energy density in diets for lori-bakhtiari lambs during a fattening program
Authors
abstract
forty growing ram lambs (lori-bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in iran. the feed intake (fi), body weight (bw), gain to feed ratio (g:f) and carcass characteristics were studied. four treatments differed in metabolizable energy content (me) as follow; 2, 2.3, 2.6 and 2.9 mcal/kg for treatments 1 to 4, respectively. the study lasted 120 days and all the experimental lambs were slaughtered and carcass composition was compared among treatments. average daily gains were 230, 252, 267 and 259 g/d for treatments 1 to 4, respectively (p

full textReference Gene Selection in Adipose and Muscle Tissues of Fat-tailed Lori-Bakhtiari Lambs
BACKGROUND: Fat-tailed sheep breeds have a unique ability to tolerate periods of negative energy balance due to seasonal changes in feed availability. This ability is attributed to presence of fat-tail as a body energy reserve, however the exact underlying mechanisms controlling the response of adipose tissue depots to variations in energy balance in fat-tailed breeds a...
