Abstract - The objective of this work was to evaluate the characteristics of the maternal-offspring behavior of Guzerat bovines (Bos indicus) and the influence of this behavior on herd losses. A total of 73 gestating cows (multiparous and primiparous) and their respective calves were evaluated for the following behavioral traits: contact period between cow and calf (CPCC), cow age at calving, teat conditions, calf vigor at birth, need for human assistance (HA), and calf mortality until weaning. The mean weight of calves at birth was 29.12 kg. Vigor at birth was observed in 61.64% of calves; however, 27.4% of the calves required human assistance. Calf vigor was influenced by the CPCC, and calves without vigor needed more time with their mothers. Calves with low weight at birth required HA, whereas calves from cows with intermediate-sized teats did not. The absence of vigor at birth increased the mortality rate. The traits age of cows and vigor of calves at birth influence both the need for human assistance to calves in their first hours of life and herd losses. Resumo – O objetivo deste trabalho foi avaliar as características do comportamento materno-filial em animais da raça Guzerá (Bos indicus) e a influência desse comportamento nas perdas do rebanho. Utilizaram-se 73 fêmeas (multíparas e primíparas) e seus respectivos bezerros para avaliação das seguintes características comportamentais: tempo de contato entre vaca e bezerro (CPCC), idade da vaca ao parto, características do teto, vigor do bezerro ao nascimento, necessidade de assistência humana (HA) e mortalidade até o desmame. A massa média dos bezerros ao nascimento foi de 29,12 kg. O vigor ao nascimento foi observado em 61,64% dos bezerros; no entanto, 27,4% dos bezerros necessitaram de HA. O vigor dos bezerros foi influenciado pelo CPCC, e bezerros sem vigor necessitaram de maior tempo com suas mães. Bezerros com baixo peso ao nascer precisaram de HA, mas bezerros de vacas com tetas de tamanho intermediário não. A ausência de vigor ao nascimento aumentou a taxa de mortalidade. As características idade da vaca e vigor dos bezerros ao nascimento influenciam tanto a necessidade de assistência humana aos bezerros, nas primeiras horas de vida, como as perdas no rebanho.

In Brazil, grain sorghum has been mainly grown in Cerrado biome during the offseason, as a succession crop, after the soybean harvest. At this period, rainfall is erratic and insufficient, causing drought stress in pre- or post-flowering of grain sorghum crops. In this scenario, the identification of both drought-tolerant and irrigation responsive hybrids has been one of the main targets of sorghum breeding programmes. The hypothesis of this research was that grain sorghum genotypes respond differently to different moments of water deficit. This study aimed to evaluate the agronomic performance of sorghum hybrids under full irrigation and drought stress at pre- and post-flowering, in order to identify hybrids tolerant to drought stress and responsive to the water supply. Field trials were carried out in Nova Porteirinha during the 2017/2018 and 2018/2019 crop seasons. Twelve grain sorghum single-hybrids were evaluated for days to flowering and grain yield in three water availability conditions: drought stress at pre-flowering, drought stress at ostflowering and full-irrigation (control). Tolerant hybrids were identified under both pre- and post-flowering drought stress, as well as hybrids responsive to irrigation. The hybrids 1G282 and 116,748 stood out in the 2017/18 season for high yield and earliness under both drought-stress conditions, while the hybrid 1G282, AG1090, AS4625 and DKB590 stood out for the 2018/19 season in both stress condition. The hybrid A9904 and 1G282 stood out for its responsiveness to water supply, being recommended to high-tech farming systems that employ irrigation or for in-season cultivation.
