Researches Regarding Growth Speed in Crossbreeds Lambs Lacaune x Spanca Reared in the Westen Area of Romania

Abstract

Aim of this paper was the monitoring of average daily weight gain, from birth until 35 days, of crossbreeds Lacaune x Spanca lambs. Researches were carried out in S.C. Unicon 2000 3N SRL from Arad County. Results of the present study revealed that body weight at birth, 9 and 35 days, and average daily weight gain 10 to 35 days and 0 to 35 days are significantly higher in crossbreed lambs Lacaune x Spanca born as singles (n=9), comparative with those born as doubles (n=6). Results suggest that single lambs crosses between Lacaune and Spanca during first 35 day of life, achieve on average daily weight gains of 232 g, a value very similar to the value of the Lacaune standard breed for meat-blood line (246 g).
