ABSTRACT.
The aim of the experiment was to study diurnal variation in water-soluble carbohydrate (WSC) concentrations in leaf and stem of tall fescue and lucerne in autumn and to determine the impact of these changes on the rate and the extent of in vitro fermentation. Vegetative herbage of lucerne and tall fescue were sampled at 0900, 1300 and 1700 h, following three consecutive regrowths between April and May. Whole plants, leaf and stem were analysed for chemical composition and in vitro gas production. There was a linear increase in WSC throughout the day for all plants and plant components (P < 0.001). In both fescue and lucerne, this rise resulted in an increased rate of gas production, although this relationship was more pronounced in fescue. Use of time of day to govern grazing management decisions to potentially improve the rumen supply of WSC and nitrogen in autumn can be achieved from tall fescue or lucerne pastures.

Abstract:
This study aimed to evaluate the influence of temperament and parity on milk production and metabolic responses of Holstein cows in a pasture-based automatic milking system. Thirty-five primiparous and 58 multiparous cows were classified as ?calm?, ?intermediate? or ?reactive? in each of the temperament tests conducted: milking reactivity (MR), race time (RT), flight speed, and flight distance. The milk yield and milk composition, as well as the blood biochemistry, were measured during the first 10 weeks of lactation. Primiparous cows produced less milk than multiparous cows (24.0 ± 0.8 vs. 34.2 ± 0.6 L/d, respectively, P ? 0.0001), while the serum beta-hydroxybutyrate concentration differences according to parity were not detected. Multiparous cows that were classified as ?reactive? on MR and RT tests produced 3 kg/d more milk and had greater concentrations of milk components than ?calm? cows (P ? 0.05). There was no such relation in primiparous cows. Also, cows scored ?reactive? on RT showed greater milking frequency (2.50 ± 0.05 vs. 2.35 ± 0.04 milking/d; P = 0.01) and blood beta-hydroxybutyrate concentrations (1.28 ± 0.09 vs. 0.92 ± 0.10 mmol/L; P = 0.04) than RT ?calm? cows. In conclusion, the cows' temperament was associated with milk production and metabolism, which depended on parity and the temperament tests used. Although productive performance was different between parities, lipomobilization was not. |
