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

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...
