THE STUDY OF THE REPRODUCTION INDEXEX OF DEVELOPMENT AND OF THE CORPORAL CONFORMATION AT CARPATINA BREED RAISED IN THE NORTH-EAST PART OF ROMANIA

C. PASCAL

Abstract


The researches have been made on goat nucleuses that are in breeding and exploitation in the private sector from the Iasi, Suceava and Botosani County. The goat population breded in these areas are from the Carpatina breed and are very well adapted to the specific geoclimate conditions. The effected study has had as principal objectives the determination of the specific indexex to the reproduction function but there have been analysed divers aspects at the youth category and at the adult ones. To estimate correctly the corporal development grade and of the conformation there have been made surveies and weightings, the resultes beening cetralised, statisticly processed and after that interpreted.
During the interpreted researches there has been established that the calculated value for the fertillity index at those three populations has been situated between the limites 130,33% and 133,33% with a average on the total effectiv of 132,29%. The fecundation has had an average value on the total analyssed effective of 95,83% with values specific to each population that are situated very close to these one. The total of the obtained values can be considerated in the biological limits of this species.
Analysing the prolificity index, on the female livestock, the registered values have variated between the limites of 134,74% and 140,36%. These differeces can be placed on the different maintenance situation of the adult goats in the first moment of the reproduction season. In case of the young categories the corporal development nas been studied separated on those two periods: in the nursing period and after weaning the kid. In the mascules case, the average of the corporal weight determined at birth has been of almost 3 kg, but registering differeces in function of the birth type: 3,221 kg at those from simple births and OG 2,865 kg at those resulted from multiple births. At females, the corporal average corporal weight at birth have been with almost 10% smaller in comparation with those determined for kid mascules are framed in the potential biological limites that this goat specie desposes of. More than that, the medium values presented, as the coefficient of variability, expresses a good development interuterine at kids, this oweing to the good alimentation of the adult famels during the pregnancy period
