Impact of increasing grain feeding frequency on production of dairy cows grazing pasture

Effect of increasing pasture allowance and concentrate supplementation on animal performance and microbial protein synthesis in dairy cows

“…The area offered daily in the low pasture allowance (124 m 2 cow -1 ) was 29.5% less than in the high pasture allowance, which is similar to the average reported by Pulido et al (2010) and higher in 30 m 2 than in the report of Pérez-Prieto et al (2011). Similar pasture allowances were used in spring grazing by (Pulido et al 2009) but with higher pre-grazing herbage mass. According to Sairanen et al (2006), a pre-grazing herbage mass lower than 2700 kg DM ha -1 limits pasture intake without regard to the given surface, strongly increasing the difficulty of biting the grass.…”

Milk production, grazing behavior and nutritional status of dairy cows grazing two herbage allowances during winter

“…Diets based on grass silage are characterized by a high level of fast degraded CP in the rumen and by being unable to improve rumen synchrony between energy and protein from the diets. Therefore, the supply of carbohydrates throughout an energetic concentrate is important for the rumen microbial metabolism due to their capacity to modify molar proportions of volatile fatty acids (Pulido et al, 2009), enhancing propionate concentrations, the most relevant precursor of glucose in ruminants, and therefore positively influences the energy metabolic status in the cow (Hall and Huntington, 2008).…”

The effect of pasture allowance and concentrate supplementation type on milk production performance and dry matter intake of autumn-calving dairy cows in early lactation

“…Some common aspects of the grazing management in the south of Chile have been described by Pulido et al (2009). Dairy cows are usually fed concentrates twice daily at milking and given new pasture after each milking.…”
