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.

Rezumat
Pentru ameliorarea productiei de lapte la populatiile autohtone de capre apartinând rasei Carpatine s-au efectuat încrucisarea cu rasa Saanen, evaluându-se performantele hibrizilor comparativ cu rasa autohtona, urmarindu-se crearea primelor verigi a unor noi populatii de caprine cu performante productive superioare.
Cercetarile s-au efectuat pe trei populatii de caprine autohtone, lucrarile fiind coordonate de ICDCOC Palas-Constanta, cu participarea a doua unitati de cercetare si anume: SCDCOC Reghin-Mures si SCDCOC Popauti-Botosani.
Productiile de lapte realizate la metisii F1, la prima fatare au fost superioare populatiilor locale astfel:
- metisii F1 Saanen x Populatia locala-Palas - au realizat o productie totala de 262,20 ± 14,51 litri fata de 204,20 ± 12,54 litri la Populatia locala-Palas;
- metisii F1 Saanen x Populatia locala-Reghin - au realizat productia totala de 291,1 ± 7,84 litri fata de 207,94 ± 4,23 litri la Populatia locala-Reghin;
- metisii F1 Saanen x Populatia locala-Popauti - au realizat o productie totala de 265,07 ± 6,48 litri fata de 207,05 ± 8,63 litri la Populatia locala-Popauti.
Concluzia generala rezultata în urma experientelor efectuate este aceea ca prin utilizarea tapilor din rasa Saanen în încrucisari cu rasa Carpatina din diferite zone s-a obtinut prima generatie de capre hibride care detin 50% rasa Saanen, respectiv 3 populatii de metisi care au avut performante semnificativ mai bune fata de rasa Carpatina în privinta productiei de lapte.
