The objective of the study was to contribute to the characterization of the serrana breed, in particular, on the meat production aspects. For this purpose, two studies were carried out. In first one evaluated the sex effect (male, female), litter size (simple, double, triple), mother¿s age (1, 2, 3, 4 and =5 years old), birth season (spring, summer, autumn and winter) and birth year (2001, 2002, 2003) over the weight at birth, adjusted weights at 30 days and 60 days, average daily weight gain from birth up to 30 days of age and average daily weight gain from birth up to 60 days of age . the results showed that the male kids, those born as a result of a simple parturition and those from older females were heavier at birth, at 30 and 60 days of age and had better average weight gain from birth to 30 days and from birth up to 60 days of age. Differences were also observed as an effect of the birth season. the second study was carried out in 60 transmontano kids carcasses (31 males and 29 females) in view of determining the sex and carcass weight effect over some conformation measurements (leg and carcass lengths, rump and thorax width, rump perimeter, compacity indexes), on longissimus muscle thickness measurements (a, b and area), fat thickness measurements (c, j, ege2, ege3, ege4), regional composition (proposed joints of the estaí§í£o zootécnica nacional de braganí§a), tissue composition (muscle, bone and fat) and on the meat ph and colour. with the tissue composition the muscle/bone and muscle/fat ratios were obtained. Furthermore a study on the relative growth of the carcass joints and its tissue composition, by means of the huxley exponential equation on its logarithmic transformation (log y = log a + b log x) was undertaken. Finally, prediction equations of the carcass composition were estimated by using both conformation and the longissimus dorsi measurements. An analysis of linear association was carried out and those measurements which were significant
