ABSTRACT.- Animal performance, carcass and meat quality characteristics of beef cull cows under different feeding strategies were compared. Cows were assigned to one of four grazing treatments combining different levels of forage allowance (FA) and supplementation rate (%of body weight, BW) using rice bran (RB): T1= FA2 % + RB0,T2 = FA4 % + RB0, T3= FA2 %+ RB 0.8 % and T4 = FA2 % + RB 1.6 %. Cows from T1 presented lower (P < 0.05) slaughter weight (SW) than the other three treatments. Additionally, T1 presented lower body weight (P < 0.05) for rump and loin, striploin, sirloin, inside round and tritip, compared to T2, T3 and T4. Intramuscular fat (IMF), pH(48h), Warner-Bratzler shear force (WBSF? aged for 7or 21 days), lean colour, saturated fatty acid (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) concentrations did not differ among treatments (P > 0.05). Nonetheless, differences between treatments were found in n6 and n3 fatty acid contents (P< 0.05). The strategic use of low supplementation rates using rice bran on an oats forage crop improved certain meat and carcass quality traits of cull cows. .-.-.-.-.-.-.-.

ABSTRACT. - The objective was to evaluate the ingestive behavior of Angus yearling steers grazing natural grasslands of Southern Brazil, submitted or not to the application of fertilizers: NG= natural grassland; FNG= fertilized natural grassland, and FONG= fertilized natural grassland improved with the over sown of temperate forage species. Three Angus yearling steers and a variable number of put-and-take animals were used per experimental unit, to maintain a forage allowance of 13 kg of dry matter/100 kg of body weight. Ingestive behavior of tester animals was visually assessed in four seasons of the year through instantaneous records of activity every ten minutes during the daytime period. There was no effect of pasture treatments on ingestive behavior. An interaction between seasons and periods of the day was observed for daily grazing and rumination time (P <0.05). The grazing activities were clustered at the beginning and the end of the day in summer, autumn and winter, while in spring it was similar in the 1st three quarters of the day, with higher activity in the period close to sunset. The animals spent more time grazing in the spring despite the better quality of forage in this season. Regardless of the season, longer residence and grazing time were found in water foci areas. We conclude that grazing time on natural pastures is influenced by forage mass and forage allowance, and bite rate is influenced by the chemical composition of the sward © 2022, Australian Journal of Crop Science.All Rights Reserved.
