| Popis: | Ovine rearing represents a domain being in a full development process in Romania. At the base of this tendency are the solicitation of local and external markets for basic production, respectively meat and milk. To record favourable economical results farmers wants to apply the most optimal technologies so, economical efficiency to reach a maximum level for each female which is part of the livestock (Pascal, 2015, Daraban 2006 ). One of those technologies refers also at precocious utilisation at reproduction of a female youth. So, the aim of effectuated research was represented by studying of possibilities for utilization at reproduction of female youth at an age still from the first year of life.Biologic material was represented by domestic ovine, from Ţigaie breed, reared in different farms situated in the North-East part of Romania. Experimental batches were formed by females with different ages, but all of them being utilized for the first time at mating. Respecting those demands were formed three batches differentially by age between them, which had, at the moment of utilization for reproduction, 9 months (L1), 18 months (L2) and 22 months (L3). Control batch was formed by adult females belonging to the same breed (LM). In the current research were tracked more aspects, the most important being the ones in which were analyzed the influence of sheep’ age on specific indexes of reproduction function, on the total duration of gestation and on further corporal development of youth females. The obtained data were statistically processed using ANOVA software, and for determination of differences and their signification were utilized Fisher and Tukey tests. The obtained results allow us to enlightened the fact that even, in case of batches formed by female youth, the mean values for studied parameters were very close to the ones specific to adult sheep, differences are significant in majority of situations for p >0.01. |
