This study aimed to measure the male genital tract of goats and establish the correlations between the different constituents of the tract and body weight. Twelve pubescent goat males (six 3/4 Anglo nubian × 1/4 SRD and six 3/4 Boer × 1/4 SRD) males were used, with an average age of approximately nine months and weights of 20.53 ± 0.60 kg and 20.94 ± 0.55 kg, respectively. The animals were kept under intensive management with balanced feeding. The diet was provided in the 70:30 ratio (bulky:concentrate) and elaborated to contain 16% crude protein and 75% of Total Digestible Nutrients (TD). The animals were weighed and slaughtered, and the genitals were collected, identified and frozen for further laboratory measurement. Bulbouretrais were also measured in vivo by ultrasound regarding width, and the rectal touch was performed to determine the location, size, consistency and symmetry of these glands. The results were expressed in mean and standard deviation and the parameters weight, width, thickness and length of the different structures of the reproductive system were submitted to student's t-test at 5% probability. A positive correlation was observed between body weight and the structures analyzed, as well as with testicular measurements of length, width and thickness. Testicular weight had a high positive correlation with the length of the epididymis, but low correlation with the length of the vesicular and bulbish glands. The results obtained in this study sometimes differ from those found in the literature, and due to the characteristics of the goat reproductive system, especially testicularones, vary according to race, weight, climate, among other variables, it is it is necessary to know the parameters of the male genital tract of breeds created in northeastern Brazil in order to obtain greater success in choosing breeders and a better genetic gain in the herds of this region.

In this sense, the present work aimed to find regression equations for prediction of body weight of Morada Nova sheep. The experiment was conducted in two locations, the Experimental Farm Lavoura Seca, in the municipality of Quixadá - CE, and the Center for Teaching and Studies in Forage (NEEF-UFC), in Fortaleza-CE. We used 221 sheep of the breed morada nova, of these: 169 females and 52 males. The measurements were performed with the aid of a morphometric ruler, and with it the following measurements were measured: Sternal Height (HS), Body Length (LC), Chest Width (WL), Croup Height (HC), Croup Width (WL), Croup Length (CL), and a tape measure was also used for the following measurements: Thoracic Perimeter (TP), Forearm Circumference (AC) and Shin Circumference (SC). The equations for females had a lower fit than that of males, several factors may explain this situation, and the different growth curve of males and females is one of these factors. Equations were also generated for red and white varieties, which should be generated independently because the two varieties are from different genetic groups. The morphometric measure that showed the greatest relationship with body weight was Thoracic Perimeter (TP), which was present in all equations, for both sexes and varieties. The equations with a greater number of variables have a higher coefficient of determination (R²), however, the execution is more laborious. Based on the results of the present study, the equations PC = -3.67 + 0.0067.PT² for the red variety and PC = 3.42 + 0.000062.PT³ for the white variety should be used, as they present high and positive R², in addition to greater practicality.
