ABSTRACT This study aimed to evaluate the milk fatty acid (FA) composition of unsupplemented dairy cows grazing on elephantgrass (Pennisetum purpureum Schum. cv. Pioneiro) pastures under three grazing management strategies: pre-grazing height of 120 cm with defoliation intensities of 50 and 70% of the initial height (treatments 120/50 and 120/70) and pre-grazing height of 90 cm with defoliation intensity of 70% (treatment 90/70). Treatments were repeated three times in a complete randomized block design. Tester animals were six multiparous Holsteins […]

The objective of this study was to evaluate the chemical composition and the fatty acid profile of the longissimus dorsi muscle and the backfat thickness of Red Norte and Nellore young bulls finished in feedlot. Fourty-four animals (22 Red Norte with initial average weight of 367±30 kg and 22 Nellore at initial average weight of 361±30 kg) were used. The animals were fed ad libitum during 112 days, slaughtered at 519 and 482 kg, respectively. Samples of the longissimus dorsi […]

Two height cuttings of corn silage with or without enzyme inoculants were evaluated for 68 days on performance, carcass characteristics, meat quality and chemical composition of the Longissimus muscle in crossbred bulls (F1 – ½ Nellore vs. ½ Angus) finished in feedlot. Thirty-two 20-month-old bulls, with initial average weight of 374±25 kg, were kept in individual pens (10 m2). Diets consisted of 50% roughage and 50% concentrate, with an expected 1.80 kg/day weight gain. The experimental design with four diets […]
