| ABSTRACT An evaluation of the effects of monensin and calcium propionate on the in vitro kinetics of gas production, digestibility, carbon dioxide, and minor gas production on different days was performed using the ruminal fluid from eight Suffolk lamb donors, after receiving additives for 1, 10, and 20 days. Treatments consisted of a control ration of 40% grain; 30 mg/kg of monensin in a diet with 40% grain; 10 g/kg calcium propionate in a diet with 30% grain; and the combination of both additives in a diet with 30% grain. The gas production was measured up to 72 h of incubation and all incubation procedures were repeated three times on days 1, 10, and 20. On incubation day 20, the volume and production of methane and minor gases were measured. There was... |

| ABSTRACT The objective was to evaluate the addition of antibiotic growth promoters to free-choice mineral supplement on ingestive behavior, mineral intake, and growth performance of grazing bulls. Sixty Nellore bulls [initial body weight (BW) of 219±17.8 kg and 15±2 months of age] were divided in 12 marandu grass paddocks. The treatments were: mineral supplement (control), mineral supplement + virginiamycin (VIRG), mineral supplement + lasalocid sodium (LASA) and mineral supplement + salinomycin sodium (SALI). Mineral supplements were formulated with target intake of 60 g d−1 and the growth promoters of 75 mg 100 kg−1 of BW. The experimental design was the completely randomized blocks. There was no treatment effect on ingestive behavior or mineral intake;... |

| The objective of this paper is to assess the effects of the inclusion of different levels of green propolis extract in the diet of lambs in feedlot on ingestive behavior, nutrients digestibility, physiological parameters and performance. Eight lambs were distributed in double Latin Square with four treatments, corresponding to the inclusion levels (4, 8, 12, 16 mL) of green propolis ethanolic extract (30 g of ground crude propolis was infused in a 100-mL hydroalcoholic solution, 700 mL/L). The diets were composed of Brachiaria brizantha cv. MG5 hay and a commercial concentrate (roughage:concentrate ratio was 50:50) in a dry matter basis. No effect was observed on dry matter (31.2 g/kg of BW), crude protein, ether extract, neutral detergent fiber,... |

| Ionophores are antibiotics that are sometimes added to cattle and poultry feed, improving feed efficiency and growth rate, The ionophores currently approved for use are safe at the prescribed levels for the indicated species, Feed containing ionophores are dangerous for horses because they are more sensitive to ionophore toxicity than other species and can lead to sudden death. In this paper we will discuss the ionophore toxicity for horses, pathogenesis, clinical signs, pathology findings, diagnosis and treatment, |

| Objetivou-se avaliar o uso da monensina sódica (Rumensin®) e da levedura viva (Saccharomyces cerevisiae - Beef - sacc®) sobre a concentração de ácidos graxos de cadeia curta (AGCC), amônia e pH ruminal, e eficiência microbiana em bubalinos e bovinos, alimentados com dietas com 50% de concentrado. Foram utilizados três búfalos e três bovinos portadores de cânulas no rúmen e no duodeno, distribuídos em dois quadrados Latinos, com arranjo fatorial 3 x 2. As concentrações de AGCC, amônia e o pH ruminal foram determinados a cada 2h. Os fluxos de digesta e proteína microbiana no duodeno foram determinados, respectivamente, por meio dos indicadores cinza insolúvel em ácido e as bases purinas. Não houve efeito dos aditivos e das espécies para a... |
