Abstract
The purpose of this paper is to present a summary with reference to the reproductive and morfologigical parameters specific to local populations of goats raised in north-east of Romania. The research was conducted on a number of 955 individuals, divided into six populations. Working methods used are specific to this type of research and refers to the macro and microscopic measurements, free assessments and statistical analysis. As a result of body measurements, it appears that goat populations studied have a mid-body development, with height of 72.5 cm for males and 64 cm in females. Regarding the exterior features, uniform white color has been shown to over 32% of individuals, horn at 50.44% and beard to over 90% of goats studied. Regardless of color or body region where it was harvested, the hair has an average length of 12 cm, is devoid of undulations and is characterized by an average of over 104 µ thick. In terms of reproductive parameters, goat populations in north-eastern Romania is characterized by a 97.4% fertility and prolificacy of 129.6%. Evaluating these parameters, it is clear that local populations of goats raised in the north-east of Romania are relatively homogeneous if we consider the degree of physical development, or the presence of beard, but highly heterogeneous in terms of coat color.

Rezumat
Scopul acestei lucrari este acela de a prezenta o sinteza cu referire la parametrii morfologigi si reproductivi specifici populatiilor locale de caprine crescute īn nord-estul Romāniei. Cercetarile s-au efectuat pe un numar de 955 de indivizi, īmpartiti īn 6 populatii. Metodele de lucru folosite sunt specifice acestui tip de cercetare si se refera la masuratori macro si microscopice, aprecieri libere si calcule statistice. Īn urma efectuarii masuratorilor corporale, se poate constata ca populatiile de caprine studiate au o dezvoltare corporala mijlocie, cu talia de 72,5 cm la masculi si 64 cm la femele. Referitor la particularitatile de exterior, s-a evidentiat culoarea alb-uniforma la peste 32% dintre indivizi, prezenta coarnelor la 50,44% dintre acestia, iar barbisonul la peste 90% dintre caprinele studiate. Idiferent de culoare sau de regiunea corporala de unde a fost recoltat, parul are o lungime medie de 12 cm, este lipsit de ondulatii si se caracterizeaza printr-o grosime medie de peste 104 µ. Din punct de vedere reproductiv, populatiile de caprine din nord-estul Romāniei se caracterizeaza printr-o fecunditate de 97,4% si o prolificitate de 129,6%. Īn urma evaluarii acestor parametri, se poate constata ca populatiile locale de caprine crescute īn partea de nord-est a Romāniei sunt relativ omogene daca ne referim la gradul de dezvoltare corporala sau la prezenta barbisonului, dar foarte heterogene īn ceea ce priveste culoarea īnvelisului pilos.
