Abstract
This paper presents some results obtained in a study on meat breed reared Charolaise in pedo-climatic conditions of N-E area of Romania and France. We followed the rearing conditions, meat characteristics and the most important selection heads indices."LUCOSDIOV" company in which was conducted this study, have a herd of 225 heads, of which 100 cows and 125 heads of youth of different ages. At birth calves had an average weight of 47.09 ± 0.701 kg, s = 5.332 kg, at 210 days 281.94 ± 5.84 kg, s = 34.581 kg and the average daily gain (ADG) was 1150.74 ± 22.291 g. Calving ease index (IFNAIS) at ascendancy of the first two generations had mean values ranking from 91.31 to 99.26, the lowest value occurring in father's father (FF) - 91.31. Also, synthetic index ISEVR at weaning had average ranking from 95.37 (MF) to 102.84 (FF) and precision (CD) had values between of 0.51 to 0.84. The values obtained by us on Romanian livestock are close to those obtained on livestock from France, namely: IFNAIS - 96.39 ± 0.241; ISEVR - 110.39 ± 0.156 and CD-0.86. The analyzed selection indexes had a genetic determinism (h2) medium to strong, as follows: ISEVR- h2= 0.26, IFNAIS- h2= 0.28, ADG- h2 = 0.45. The performed study on Charolaise meat breed raised in Romania showed that the animals had a very good body development confirming characteristic for meat breeds.
