Abstract
To improve the milk production at the local populations of goats belonging to Carpathian breed, it was made the crossbreeding with Saanen breed, evaluating the performances of the hybrids comparatively to the local breed, aiming to create the first new rings of new goat populations with superior productive performances.
The researches were made on three local populations of goats, the works being coordinated by ICDCOC Palas-Constanta, with the participation of two units of research: SCDCOC Reghin-Mures and SCDCOC Popauti-Botosani.
The milk productions made at the F₁ half-breeds, at the first dropping were superior to the local populations as follows:
- F₁ Saanen half-breeds x local population -Palas - made a total production of 262.20 ± 14.51 liters besides 204.20 ± 12.54 liters at the local population -Palas;
- F₁ Saanen half-breeds x local population -Reghin - made a total production of 291.1 ± 7.84 liters besides 207.94 ± 4.23 liters at the local population -Reghin;
- F₁ Saanen half-breeds x local population-Popauti - made a total production of 265.07 ± 6.48 liters besides 207.05 ± 8.63 liters at the local population -Popauti.
The general conclusion which resulted from the experiment is that by using the bucks of Saanen breed, in crossbreeding with Carpathian breed from various areas it was obtained the first generation of hybrid goats which have 50% Saanen breed, respectively 3 genotypes which had significantly better performances au than the local breed regarding the production of milk.
