It remains unknown whether dairy cows with more reactive temperament produce more enteric methane (CH4) and are less bioenergetically efficient than the calmer ones. The objectives of this study were (a) to evaluate the relationship between cattle temperament assessed by traditionally used tests with energetic metabolism and enteric CH4 emissions by crossbred dairy cows; (b) to assess how cows? restlessness in respiration chambers affects energetic metabolism and enteric CH4 emissions. Temperament indicators were evaluated for 28 primiparous F1 Holstein-Gyr cows tested singly in the handling corral (entrance time, crush score, flight speed, and flight distance) and during milking (steps, kicks, defecation, rumination, and kick the milking cluster off). Cows? behaviors within respiration chambers were also recorded for each individual kept singly. Digestibility and calorimetry trials were performed to obtain energy partitioning and CH4 measures. Cows with more reactive temperament in milking (the ones that kicked the milking cluster off more frequently) spent 25.24% less net energy on lactation (P = 0.04) and emitted 36.77% more enteric CH4/kg of milk (P = 0.03). Furthermore, cows that showed a higher frequency of rumination at milking parlor allocated 57.93% more net energy for milk production (P < 0.01), spent 50.00% more metabolizable energy for milk production (P < 0.01) and 37.10% less CH4/kg of milk (P = 0.04). Regarding the handling temperament, most reactive cows according to flight speed, lost 29.16% less energy as urine (P = 0.05) and tended to have 14.30% more enteric CH4 production (P = 0.08), as well as cows with a lower entrance time (most reactive) that also lost 13.29% more energy as enteric CH4 (P = 0.04). Temperament and restless behavior of Holstein-Gyr cows were related to metabolic efficiency and enteric CH4 emissions. Cows? reactivity and rumination in the milking parlor, in addition to flight speed and entrance time in the squeeze chute during handling in the corral, could be useful measures to predict animals more prone to metabolic inefficiency, which could negatively affect the sustainability of dairy systems.

Common beans "Jalo" type has yellow and large grains, and usually reaches the higher market prices. However, most of the cultivars with this grain type present some problems as susceptibility to pathogens, especially Erysiphe poligoni, causal agent of powdery mildew disease, which can cause significant losses in grain yield. Availability of cultivars "Jalo" grain type is limited. Thus institutions that work with common bean breeding in Minas Gerais, Brazil, Universidade Federal de Lavras (UFLA), Universidade Federal de Viçosa (UFV), Empresa de Pesquisa Agropecuária de Minas Gerais (Epamig) and Empresa Brasileira de Pesquisa Agropecuária (Embrapa), have evaluated lines with this grain type, aiming to obtain and recommend new cultivars that are superior to "Jalo EEP 558" cultivar, which was indicated to Minas Gerais state in 1980. Result of this work, is recommendation of BRSMG União cultivar, a new option of common bean cultivar type "Jalo", for the state of Minas Gerais. |
