“…Growth parameters are also associated with the final weight and hip height at the end of fattening in feedlot tests (Morsy et al, 1998). Veal carcass quality and models of growth are influenced by different management and feeding conditions, as describes Domaradzki et al (2017).…”

Bali cattle are one of the native cattle breeds in Indonesia as a meat producer. The objective of this study was to analyze the correlation between body weight and scrotal circumference and sperm quantity of Bali bulls. To accomplish this objective, primary and secondary data of Bali bulls in Baturiti Artificial Insemination (AI) Center, Bali from 2017 to 2019 were used in this research, consisted of scrotal circumference (SC), body weight (BW), semen volume (SV) and sperm concentration (SCon) (n = 9 bulls in productive age). Total Number Sperm (TNS) was calculated multiply value of SV and SCon. The data were analyzed statistically using Correlation Pearson Square. There was no significant correlation among body weight, scrotal circumference, and sperm quantity of Bali bulls in this research (P>0.05). Low positive correlation was found between BW with SC (0.296), very low positive correlation with SV (0.049), very low negative correlation with SCon (−0.089) and moderate positive correlation with TNS (0.427). Moreover, SC showed low negative correlation with SCon (−0.202), very low negative correlation with SV (−0.028) and low positive correlation with TNS (0.286). In conclusion, BW showed positive correlation SC, SV and TNS, but showed a negative correlation SCon. SC had positive correlation with TNS but they showed negative correlation with SV and SCon of Bali bulls.

RESUMO -Um experimento foi conduzido com o objetivo de avaliar o desenvolvimento ponderal e testicular, as concentrações periféricas de testosterona (T) e características de abate, dos 10 aos 30 meses de idade, em tourinhos da raça Nelore (n=27). Entre 11 e 21 meses, os animais foram tratados com GnRH e amostras de sangue, coletadas 0, 1,5 e 3,0 horas depois. Aos 30 meses, os animais foram abatidos. O peso vivo (PV) dos animais variou de 195,2 ± 3,8 kg a 439,1 ± 8,1 kg entre 10 e 30 meses e o rendimento de carcaça foi de 55,4 ± 2,3%. Os pesos dos testículos (PT) e do epidídimo (PE) aos 30 meses foram 160,9 ± 7,7 g e 20,4 ± 0,62 g, respectivamente.As concentrações de T apresentaram crescimento maior entre 16 e 18 meses e o tratamento com GnRH ocasionou aumentos nos níveis de T em todas as idades. As concentrações de testosterona estimuladas com GnRH estiveram associadas às concentrações basais (r = 0,41 a 0,63). Houve correlações entre PV e circunferência escrotal (CE) em todas as idades (r = 0,41 a 0,70). O peso corporal entre 10 e 30 meses apresentou correlações com PT (r = 0,48 a 0,62) e PE (r = 0,48 a 0,73) aos 30 meses e animais com maior peso de carcaça também tiveram maiores pesos testicular (r = 0,45) e epididimal (r = 0,63). Houve correlações entre PV (10 e 30 meses) e peso da carcaça (r = 0,65 a 0,93), mas o rendimento de carcaça não apresentou relação com CE, PT, PV ou níveis de testosterona. Foram significativas também as correlações entre a CE aos 30 meses e a CE avaliada entre 10 e 25 meses (r = 0,51 a 0,89). Portanto, medidas testiculares são potenciais indicadores do desenvolvimento ponderal e das características de abate na fase adulta.Palavras-chave: carcaça, circunferência escrotal, GnRH, Nelore, testosterona Testicular and Body Growth, Peripheral Concentrations of Testosterone and Carcass Parameters in Nelore BullsABSTRACT -An experiment was carried out to evaluate testicular and body growth, peripheral concentrations of testosterone (T) and carcass parameters, from 10 to 30 months of age, in Nelore bulls (n=27). Between 11 and 21 months, animals were treated with GnRH and blood samples taken 0, 1.5 and 3.0 hours afterwards. Animals were slaughtered at 30 months. Body weight (BW) varied from 195.2 ± 3.8 kg to 439.1 ± 8.1 kg between 10 and 30 months of age and the ratio BW/carcasss was 55.4 ± 2.3%. Testicular (TW) and epididimal weight (EW) at slaughter were 160.9 ± 7.7 g and 20.5 ± 0.62 g, respectively. Testosterone secretion reached higher levels between 16 and 18 months and treatment with GnRH caused increases in testosterone at all ages. Moreover, basal concentrations of T were related to those determined after GnRH (r = 0.41 to 0.63). Body weight from 10 to 30 months was correlated with SC at all ages (r = 0.41 to 0.70) and with testicular (r = 0.48 to 0.62) and epididymal weight (r = 0.48 to 0.73) at 30 months. Carcass weight was related to TW (r = 0.45) and EW (r = 0.63). Body weight evaluated from 10 to 30 months was related to carcass weight (r = 0.65 to 0.93), but the ratio BW/carcass...
