| The objective of this work was to characterize the hematological profiles of steers and bulls, according to residual feed intake (RFI), after feed deprivation. Twenty‑month‑old Nellore steers and bulls were fed feedlot diets for 70 and 56 days, respectively. RFI was calculated as the difference between actual feed intake and expected feed intake. More and less efficient steers and bulls, according to RFI, were subjected to 24 hours of food deprivation. Blood was sampled prior to and following the withdrawal period. Hematological analyses included total and differential white blood cell count, red blood cell count and morphology, and plasma glucose concentration. Variation in RFI did not influence plasma glucose concentration or blood cell profiles. Glucose... |

| O objetivo foi avaliar a acurácia, precisão e robustez das estimativas da digestibilidade aparente da matéria seca obtidas utilizando-se como indicadores fibra em detergente ácido indigestível (FDAi), fibra em detergente neutro (FDNi) indigestível, lignina em detergente ácido (LDA), LDA indigestível (LDAi) e óxido crômico em comparação ao método de coleta total de fezes. Dezoito ovinos (56,5 ± 4,6 kg PV) foram designados aleatoriamente a dietas compostas de 25, 50 ou 75% de concentrado e feno de Coast cross por 25 dias. As fezes foram coletadas por cinco dias para determinação da digestibilidade aparente da MS. As amostras de alimentos e fezes foram incubadas no rúmen de três bovinos por 144 horas, para obtenção das frações indigestíveis. Óxido crômico foi... |

| ABSTRACT: The acute phase reaction occurs in response to diseases, surgical trauma and can happen after strenuous exercise, like long distance events. This study aimed to evaluate the Serum Amyloid A (SAA), pro-inflammatory interleukins (IL-1β and TNFα) and creatine phosphokinase (CK) after free speed races like physical stress markers in endurance horses. Blood of 21 trained horses that competed in tests of 80, 120 and 160km, was taken before and after race. There was a significant increase in CK and SAA after the race in all horses, as well as the anti-inflammatory interleukin IL-10. But when results were compared between the groups, only the SAA was different, being higher in 160km horses. There was no change in pro-inflammatory interleukins IL-1β and... |
