Milk production of fall-calving dairy cows during summer grazing of grass or grass-clover pasture.
Milk production of fall-calving dairy cows during subsequent summer grazing was evaluated in two consecutive years using a total of 80 mid- to late-lactation Holsteins. Cows calved during September and October and grazed from April to August in the following year. In yr 1, 27 cows grazed a native grass pasture and 13 cows grazed a native grass-clover mixed pasture containing 26% red clover and ...
متن کاملEvaluation of a mobile computerized grain feeder for lactating cows grazing grass pasture.
The objective of this study was to evaluate a mobile computerized grain feeder for use to feed individually Holstein cows grazing grass pasture. Thirty-two Holstein cows averaging 95 d of lactation and 39.3 kg/d of milk were rotationally grazed on predominantly Dactylis glomerata pastures for 9 wk starting in early May. Cows were blocked according to parity, days of lactation, and milk yield. C...
متن کاملSward Factors Influence on Pasture Dry Matter Intake of Grazing Dairy Cows: A Review
Successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. In order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...
متن کاملEvidence of Low Sodium Status in Beef Cattle Grazing Coloniao Guinea Grass Pasture
Playne (1970) suggested that the levels of sodium (Na) in some tropical grasses are below those considered sufficient for the requirements of lactating cows. We examined the concentration of Na in guinea grass from a number of areas in Queensland. Levels in creeping guinea (P. maximum Q 8132), P. maximum cv. Coloniao, P. maximum cv. Hamil and P. maximum (C.P.I. 37910, Makeuni) ranged from 0.007...
متن کاملEffects of herbage mass and herbage quality on spatially heterogeneous grazing by cattle in a bahia grass ( Paspalum notatum ) pasture
Small-scale patches (locations of 50 cm × 50 cm at a feeding station level) in a bahia grass ( Paspalum notatum ) pasture under cattle grazing were investigated in terms of herbage mass, quality and utilisation during a grazing season (May–November), to characterise the quantityquality relationship of patches and relate this to spatially heterogeneous grazing by animals. Nitrogen concentration ...
