Maize silage for dairy cows
This paper reviews the use of maize silage in pastoral dairying systems in New Zealand. The evolution of dairying systems to make profitable use of maize silage and other supplementary feeds has occurred during the last decade in conjunction with an increased use of maize silage. When used within recommended levels of feeding, maize silage provides a low cost source of starch and fibre which co...
متن کاملPerformance of lactating dairy cows fed alfalfa silage or perennial ryegrass silage.
The nutrient contents of perennial ryegrass (Lolium perenne L.) and alfalfa (Medicago sativa L.) are reasonably similar. Despite similarities, the lactation performance of dairy cows fed perennial ryegrass has not been compared with the lactation performance of dairy cows fed alfalfa. The present study was implemented to compare the performance of lactating cows fed alfalfa or perennial ryegras...
متن کاملLactational responses to postruminal infusions of amino acids in dairy cows fed maize silage, hay or grass silage.
Duodenal infusions of methionine and ly-sine have been shown to increase milk protein yield in dairy cows given a dehydrated maize diet (Rulquin, 1987). As du-odenal amino acids (AA) profiles vary according to diet (Le Henaff, unpublished), a trial was undertaken to test the lactational responses of dairy cows to methionine and lysine infusions with 3 other diets based on either maize silage (M...
متن کاملSynthesis of microbial protein in ruminally cannulated cows fed alfalfa silage, alfalfa hay, or corn silage.
Six ruminally cannulated cows were used in an experiment with a 3 x 3 Latin square design. Three all forage diets-alfalfa silage, alfalfa hay, or corn silage plus 2.2% urea (DM basis)-were fed for ad libitum intake four times daily. The microbial protein marker 15NH3 and the liquid marker Cr-EDTA were infused continuously into the rumen for 72 and 48 h, respectively; the solid marker, Yb-labele...
متن کاملReplacing alfalfa or red clover silage with birdsfoot trefoil silage in total mixed rations increases production of lactating dairy cows.
The objective of this study was to compare milk production and nutrient utilization in dairy cattle fed silage made from alfalfa (AL) or red clover (RC) versus birdsfoot trefoil (BFT) selected for low, normal, and high levels of condensed tannins. Condensed tannin contents of the 3 BFT silages were 8, 12, and 16 g/kg of DM by butanol-HCl assay. Twenty-five multiparous Holstein cows (5 fitted wi...
