The effect of protein-feeding strategy during lactation on performance of primiparous dairy cows fed total mixed ration
Fifty primiparous Finnish Ayrshire cows were used in 2_2 factorial study. The factors were the protein-feeding strategy: constant (cCP) or variable (vCP) protein content in concentrate during lactation and the use of a ...
Effect of concentrate type on rumen fermentation and milk production of cows at pasture
Abstract The experiment was conducted with 15 Autumn-calving Holstein--Friesias, three cannula, that were allowed to access a perennial timothy and meadow fescue sward between 10 June and 12 August 1996. The control ...
Grass maturity effects on cattle fed silage-based diets : 1. Organic matter digestion, rumen fermentation and nitrogen utilization
Abstract Four silages were harvested at approximately one-week intervals from the same timothy-meadow fescue sward. Advanced maturity of the herbage was evidenced by increased neutral detergent fibre [409, 497, 579 and ...
Grass maturity effects on cattle fed silage-based diets 2. Cell wall digestibility, digestion and passage kinetics
Abstract Four silages were harvested at approximately 1-week intervals from the same timothy--meadow fescue sward and studied in a 4×4 Latin square experiment with four ruminally and duodenally cannulated young cattle. ...
