“…Com relação aos dias de coleta, verificou-se diferenças significativas para a variável hemoglobina (Hb), volume globular (VG), volume corpuscular médio (VCM) e concentração de hemoglobina corpuscular média (CHCM) (Tabela 3). No presente estudo, valores inferiores para Hb, VG e VCM foram obtidos em relação aos índices de Hb =12,8g/dL, VG=41,2% e VCM=61,83 fL, relatado para novilhas da raça Aquitânica (5/8 Blond"Aquitaine x 3/8 Caracu) acima de 12 meses de idade, criadas em regime semi-intensivo, suplementadas com milho, soja e algodão (DIAS JÚNIOR et al, 2006). Esses valores inferiores, supostamente, estão associados à conversão alimentar , sendo essa superior nas raças de origem européia e nos seus mestiços.…”

“…Esses valores inferiores, supostamente, estão associados à conversão alimentar , sendo essa superior nas raças de origem européia e nos seus mestiços. Por outro lado, nos touros Nelore o valor para o CHCM foi similar aos 31,41% observados nas fêmea da raça Aquitânica (DIAS JÚNIOR et al, 2006 Tabela 3. Médias e desvios-padrão para glóbulos vermelhos (GV), hemoglobina (Hb), volume globular (VG), volume corpuscular médio (VCM) e concentração de hemoglobina corpuscular média (CHCM) de touros da raça Nelore, com idades entre 30 e 36 meses, Presidente Prudente-SP.…”

Influência de um nutracêutico no sêmen, testosterona, cortisol, eritrograma e peso corpóreo em touros jovens Bos taurus indicus AbstractThe purpose of this study was to investigate the nutraceutic (Promater) influence on semen, body weight, eritrogram and hormones testosterone and cortisol in Nelore young bulls. Twenty Nelore bulls were utilized, aging between 30 and 36 months, divided in group 1 (G1)=10 (control) and group 2 (G2)=10 (nutraceutic group -Promater: 20 mL/animal/day, during 70 days). Corporal weight, blood samples to eritrogram, testosterone and cortisol were obtained in days zero (D0), 35 (D35) and 70 (D70) in two groups. There was difference (P<0.01) among days collected (0, 35 and 70) with means of 424.30 kg, 480.70 kg and 502.60 kg, respectively, but there was not difference between groups. There was not difference among groups to semen, eritrogram, cortisol (G1 = 3,19 µg/dL; G2 = 2,91 µg/dL) and testosterone (G1 = 274,48 ng/dL; G2 = 509,65 ng/dL). The results exposed allow concluding that were not observed significative effect of the nutraceutic upon evaluated parameters: body weight, semen, hormonal profile and eritrogram.

This study aimed to evaluate differences in efficiency of feed utilization between young Nellore males and females by comparing growth traits, feed intake, blood parameters, and ingestive behavior of the animals. Data from 768 Nellore males and females that participated in eight performance tests for individual feed intake evaluation were used. Performance and feed efficiency measures, efficiency-related hematological, metabolic and hormonal variables, and data regarding ingestive behavior were collected. Feed efficiency measures were defined by the relationship between performance and feed intake. Data were analyzed using mixed models that included the fixed effects of sex, herd, and the covariate age within sex and the random effects of facility within year, year, and residual. Significant differences between males and females were observed for traits related to weight gain and feed intake. Although individual dynamics of feed efficiency measures differed between males and females, no significant differences in residual feed intake, feed efficiency, or relative growth rate were observed between sexes. Significant differences between sexes were found for platelets, red blood cells, hemoglobin, creatinine, glucose, urea, triglycerides, insulin, cortisol, and IGF-I. Females spent more time feeding and less time ruminating when compared to males. However, males exhibited higher feeding efficiency and lower rumination efficiency than females. Growing Nellore males and females are efficient in feed utilization, and the differences in blood variables observed are probably due to differences in body size and feed intake. Males spend less time eating, consume more food, and spend more time ruminating than females.
