Crossbreeding has been used to improve performance in beef cattle, however the effects of breed composition on methane (CH4) production, yield and intensity from cattle raised in tropical intensive and integrated systems remain unknown. To assess the impact of breed composition on performance and methane emissions, Nellore (NEL; yr 1: BW = 171.5 ± 19.

Effect of Supplementation of Sorghum Silage in Weanling Fillies During the Dry Period in Brazil.

Young horses reach nearly 90% of their final height in the first year of life. However, to achieve their genetic potential, it is necessary to receive adequate nutrition during this period of rapid growth. The objective of this study was to evaluate the effect of supplementation of sorghum silage during a period of limited pasture forage availability, on the body development, and health of Mangalarga Marchador (MM) weanling fillies.

Comparison of humoral neutralizing antibody response in rabbits, guinea pigs, and cattle vaccinated with epsilon and beta toxoids from Clostridium perfringens and C. botulinum types C and D toxoids.

Rabbits and guinea pigs are used in the official control and validation of clostridial vaccines, but it is unknown whether the antitoxin titers obtained in these animals corroborate with the humoral response in bovine. The objective of the study was to compare the humoral antibody response of guinea pig and rabbits to those obtained in cattle vaccinated with a commercial vaccine containing Clostridium perfringens epsilon and beta, and Clostridium botulinum types C and D toxoids. This study revealed the same level of humoral response in rabbits and cattle for all four toxoids tested, including C.

Evaluation of the Presence and Levels of Enrofloxacin, Ciprofloxacin, Sulfaquinoxaline and Oxytetracycline in Broiler Chickens after Drug Administration.

The depletion times of enrofloxacin and its metabolite ciprofloxacin as well as sulfaquinoxaline and oxytetracycline were evaluated in broiler chickens that had been subjected to pharmacological treatment. The presence and residue levels of these drugs in muscle tissue were evaluated using an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method that was validated in this work. The results showed the presence of all antimicrobial residues; however, the presence of residues at concentrations higher than the drugs' maximum residue limit (MRL) of 100 μg kg-1 was found only during the treatment period for oxytetracycline and until two days after discontinuation of the medication for enrofloxacin, ciprofloxacin and sulfaquinoxaline.

Performance of crossbred heifers in different step-down waste milk-feeding strategies.
