Abstract:The 'INRA 180' is a new composite breed created from the Timahdite (50 %) and D'man (50 %) breeds at the INRA of Morocco. The development process were reported and the data of ewe weight, ewe reproductive and productivity, weights, growth and survival lamb traits were collected during six years and analyzed. The results showed that ewe mating age, ewe mating weight, fertility, prolificacy at birth, fleece weight and productivity at 90 days for the 'INRA 180' ewes averaged 32.7 months, 43,3 kg, 91 %, 1.60, 1.74 kg and 25.5 kg, respectively. The average body weights at birth, 30 days, average daily gain between 10 and 30 days, average daily gain between 30 and 90 days, weight at 90 days, survival at birth ant at 90 days of 'INRA 180' lambs were 3.01 kg; 7.23 kg; 129 g/d; 170 g/d; 17.4 kg, 94 % and 84 %, respectively. It seems that the new breed promise a high potential merit in the agricultural livestock systems for increasing herd productivity and ovine red meat production in Morocco.
