EFFECTS OF USING LACAUNE RAMS IN CROSSBREEDING SCHEMES WITH TURCANA BREED ON BODY DEVELOPMENT IN F1 LACAUNE X TURCANA YEARLING EWES – PRELIMINARY RESULTS

ANA GINA TRICA

Abstract


 

Objective of the current research was to evaluate the effects of crossbreeding the French Lacaune breed with Romanian indigenous Turcana sheep on body development in F1Lacaune x Turcana crossbred nulliparous, reared under extensive and semi-intensive production systems.Under extensive production system, the F1Lacaune x Turcana gimmers registered an average body weight of 48.2±0.31 kg, compared to the Turcana purebred counterparts, which had on average 45.6±0.24 kg. Differences between the two genotypes were significant statistically (p<0.05).Under semi-intensive production system, the F1Lacaune x Turcana ewe-lambs registered an average body weight of 36.6±0.19 kg, compared to the Turcana purebred counterparts, which had on average 32.9±0.31 kg. Differences between the two genotypes were significant statistically (p<0.01). Age condition the production of milk so it reses to the fourth lactation, holds in the plate one or two lactation and then decreases progressively.
