the effect of alfalfa hay particle size and soy hull on physically effective fiber content in diet, chewing activity and milk production in holstein dairy cows
this study was conducted to evaluate the effects of alfalfa hay (ah) particle size and soybean hull (sh) on physical effective fibre (pendf), particle size distribution in diets, chewing activity as well as milk composition and production in early lactating dairy cows. eight lactating holstein cows averaging 590±33 kg of bw and 47±13 days in milk were assigned in a 4×4 latin square design to a ...
متن کاملInfluence of sugary-Brawn2 or dent corn at two forage levels on intake, digestion, and milk production by dairy cows.
Sugary-Brawn2 (su-Bn2) corn endosperm contains higher concentrations of watersoluble polysaccharides than dent corn. Eight multiparous Holstein cows averaging 48 d in milk and 667 kg BW at trial initiation were in a replicated 4 x 4 Latin square design with 28-d periods. Only cows in one square were ruminally cannulated. Treatments were su-Bn2 or dent corn and 45 or 60% of ration DM as alfalfa ...
متن کاملEffect of forage legumes on feed intake, milk production and milk quality – a review*
Literature data from experiments with lactating dairy cows offered silage-based diets was reviewed to evaluate the effects of the grassland legume species Trifolium repens (WC, white clover), Trifolium pratense (RC, red clover) and Medicago sativa (M, lucerne) on feed intake, milk production and milk quality. Seven data sets were created to compare grass silage (G) with grassland legumes in gen...
متن کاملProcessing and chop length effects in brown-midrib corn silage on intake, digestion, and milk production by dairy cows.
In this experiment, we evaluated the influence of increasing chop length and mechanical processing of whole-plant brown-midrib corn silage on intake, digestion, and milk production by dairy cows. Corn silage treatments were harvested at three-quarter milk line stage of maturity at 13- and 19-mm theoretical chop length without processing, or at 19- and 32-mm theoretical chop length with processi...
متن کاملCrop processing and chop length of corn silage: effects on intake, digestion, and milk production by dairy cows.
Effects of corn silage crop processing and chop length on intake, digestion, and milk production were evaluated. Corn silage treatments were harvested at one-half milkline stage of maturity (65% whole-plant moisture content) and at 0.95-cm theoretical length of cut without processing (control) or 0.95-, 1.45-, or 1.90-cm theoretical length of cut with processing at a 1-mm roll clearance. Twenty...
