Effects of Feeding Fats on Rumen Fermentation and Milk Composition
Milk yields of high-producing dairy cattle demand that energy intake be maximized. Energy intake is not only important during the period of peak milk production but also must be sufficient to maintain persistency of production and support body weight gain following peak milk yield. To increase ration energy density, cereal grains are used to replace forages, but this practice is limited since a...
متن کاملEffect of concentrate type on rumen fermentation and milk production of cows at pasture
The experiment was conducted with 15 Autumn-calving Holstein±Friesian cows, three of which were ®tted with rumen cannula, that were allowed to access a perennial timothy and meadow fescue sward between 10 June and 12 August 1996. The control treatment (C) consisted of pasture alone. For the other two treatments, cows were fed 4 kg per day of either a concentrate supplement consisting of barley ...
متن کاملSeasonal changes in the digesta-adherent rumen bacterial communities of dairy cattle grazing pasture
The complex microbiota that resides within the rumen is responsible for the break-down of plant fibre. The bacteria that attach to ingested plant matter within the rumen are thought to be responsible for initial fibre degradation. Most studies examining the ecology of this important microbiome only offer a 'snapshot' in time. We monitored the diversity of rumen bacteria in four New Zealand dair...
متن کاملPotential Role of the Bovine Rumen Microbiome in Modulating Milk Composition and Feed Efficiency
Ruminants are completely dependent on their microbiota for feed digestion and consequently, their viability. It is therefore tempting to hypothesize a connection between the composition and abundance of resident rumen bacterial taxa and the physiological parameters of the host. Using a pyrosequencing approach, we characterized the rumen bacterial community composition in 15 dairy cows and their...
متن کاملIncubation inside the bovine rumen.
I . Details are given for the construction and use of an apparatus for the incubation of rumen liquor in semi-permeable sacs inside the bovine rumen. It was found practicable, using one animal, to incubate simultaneously samples of strained diluted rumen liquor in three identical vessels, each of 100--120 ml capacity, for periods of up to 23 h. 2. The optimal conditions for experiments of this ...
