Ninety-six Hereford cow-calf pairs grazing Campo grasslands were used in a 2 × 2 factorial design that evaluated stocking rate (high [H] vs low [L]) and creep feeding (CF; yes or no). Creep-fed calves grazing L had a greater average daily gain (1.07 ± 0.03 kg/d) than CF calves grazing H (0.96 ± 0.03 kg/d; P < 0.05), but L?CF (0.78 ± 0.03 kg/d) and H?CF calves (0.73 ± 0.03 kg/d) had similar average daily gains (P > 0.05). Similarly, L+CF calves were heavier at weaning (172 ± 3 kg) than H+CF
calves (160 ± 3 kg), but weaning weights between L?CF (144 ± 3 kg) and H?CF (138 ± 3 kg; P > 0.05) did not differ. Creep-fed calves grazed less (39 ± 10%) than non-supplemented calves (58 ± 15%; P < 0.05). Creep feeding had no effect on milk production, body condition and live weight of the dams, so it had no impact on their reproductive performance. We conclude that CF promotes greater live weight gains and weaning weights of Hereford calves grazing Campo grasslands. |

ABSTRACT.
High rates of honey bee colony losses have been reported worldwide; however, data about colony loss rates in South America is scarce. This study quantified colony losses experienced in Uruguay during the 2013?2014 season and identifies the self-diagnosed causes for these losses. An estimated 2.6% of all Uruguayan beekeepers, who collectively managed 5% of the estimated 550,000 colonies in the country, responded to this survey.We found that total summer and winter losses were similar (summer 19.0% (95% CI 13.26?24.77%), winter 20.2% (95% CI 14.98?25.39)), as were the average operational losses (summer 19.8% (95% CI 14.01?25.52), winter 18.3% (95% CI 13.15?23.56%)). The total annual loss was 28.5% (95% CI 22.42?34.51%), with each beekeeper losing, on average, 28.6%(95% CI 22.52?34.61%) of the colonies in their operation. Loss rates were similar across operations of different sizes. Queen failure, diseases and parasites, and pesticides were the leading self-reported and selfdiagnosed causes of colony losses. This study is the first to document honey bee colony losses in Uruguay, establishing a baseline for future long-term monitoring.
