Factors Affecting Dry Matter Intake by Lactating Dairy Cows
Feed intake is the single most critical factor of dairy production, and performance of dairy cattle can be enhanced or hindered by environmental factors that affect it. These environmental factors can by divided into physical and climatic conditions. On modern dairies, the physical factors may be of more concern. Modern facilities provide the cow with protection from the natural elements. Howev...
متن کاملEffects of chewing behavior and ruminal digestion processes on voluntary intake of grass silages by lactating dairy cows.
Four primiparous Holstein-Friesian cows (518 kg average BW) with ruminal and duodenal cannulas were used to examine voluntary intake of direct cut (DC) or wilted (W) grass silage in relation to ruminal characteristics and chewing behavior. Dry matter content of the silages was 17.0 and 38.1%, concentrate DM intake was restricted to 5.0 and 5.3 kg/d, and voluntary DM intake from silages averaged...
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 کاملImpact of nonfiber carbohydrate on intake, digestion, and milk production by dairy cows.
Four concentrations of dietary nonfiber carbohydrate (42, 36, 30, and 24%) were evaluated using eight multiparous Holstein cows (662 kg of BW; 63 DIM) in replicated 4 x 4 Latin squares with 28-d periods. Shelled corn and soybean meal were partially replaced with wheat middlings, dried brewers grains, and soy hulls to formulate 36, 30, and 24% nonfiber carbohydrate diets. Decreasing dietary nonf...
متن کاملImproving Dry-matter Intake of Perennial-ryegrass Pasture by Dairy Cows
Dairy cows fed on perennial-ryegrass pasture produce higher-quality milk in terms of fatty-acid composition; however, they produce much less milk compared to dairy cows under other systems. The low dry-matter intake (DMI) has been identified as the main factor responsible for the lower milk production in pasture-based systems. To maximize milk production from those systems it is important to ma...
