ABSTRACTThe effect of barley level and monensin on feedlot performance by lambs and steers was investigated in two experiments. Monensin was given at 0 and 33mg/kg of food in lamb and steer diets, which contained bailey at levels from 300 to 900g/kg. Food consumption by lambs was not affected by monensin but intakes decreased with increasing levels of barley (P < 0·05). Food intake by steers decreased in a linear manner with increasing levels of barley (P < 0·01) and averaged 80g/kg lower when monensin was fed (P < 0·05). Monensin improved lamb gains by 350g/kg (P < 0·001), but had no effect on steer performance. Feeding monensin improved average food efficiency in lambs and steers by 27 and 4%, respectively. Carcass characteristics were not influenced by monensin, but heavier carcasses (P < 0·01) in steers given the high barley rations were also fatter (P < 0·001).

Zilpaterol Hydrochloride

The objective of the present study was to evaluate the effects of supplementation of zilpaterol hydrochloride (ZH) to the finishing diets on the feedlot performance and carcass characteristics of hair sheep ewe lambs during hot environmental conditions. Twenty Katahdin × Pelilbuey and Dorper × Pelibuey crossbred females with an average initial liveweight (LW) of 26.2 ± 0.83 kg were blocked by the initial LW, and assigned individually to 20 pens in a closed calf-rearing unit provided with fans. Treatments were (1) control group (basal diet without ZH) and (2) ZH group (basal diet plus 10 mg of ZH/ewe.day). Skin temperatures were measured each 2 days in five ewes by treatment; ambient weather conditions were recorded every day. After a 34-day feeding period, all ewes were slaughtered. Climatic variables during the study showed severe heat stress, with the average temperature–humidity index and temperature 85 units and 34.1°C, respectively. The skin temperature of belly and right flank was greater (P < 0.05) in ZH females than in control lambs. Ewe lambs fed ZH had feedlot performance, carcass length, shear force, body fat and skin percentage similar (P > 0.05) to control ewe lambs. With the exception of peritoneum and head (P < 0.05), all visceral organs had similar (P > 0.05) percentages between treatments. However, hot- and cool-carcass weights, dressing percentage, conformation and rib-eye area were greater (P < 0.05) for ewes supplemented with ZH. Likewise, the weight of hindquarter, legs and ribs expressed as a percentage of hot-carcass weight increased (P < 0.05) with ZH supplementation. Growth and deposition of excessive fat in hair-sheep ewe lambs were not improved with ZH supplementation under heat-stress conditions, whereas carcass-quality traits such as dressing and rib-eye area were increased.
