Effect of Water Temperature in Rumen Temperature, Digestion and Rumen Fermentation in Sheep

Effect of lasalocid sodium on rumen fermentation and digestion in sheep.

Four adult sheep were fed 4 diets successively according to a Latin-square design. They were fitted with a rumen cannula and with simple cannulae at the duodenum and ileum. The basal diet (L0) was composed of highly-pressed ensiled sugar beet pulp (56.2%), cereal (barley and corn: 27.6%), urea (1.5%) and wheat straw (14.1%). Lasalocid sodium was added to obtain the following respective amounts:...

Effect of temperature on food and water intake and rumen fermentation.

The purpose was to determine volatile fa t ty acid concentrations at normal (18 C) and high (35 C) ambient temperature, and to determine the effect of increasing the rumen temperature with an intraruminal heating coil in an 18 C ambient temperature. Four nonlactating, fistulated Holstein cows were placed in a climatically controlled chamber. Treatments were (18) ambient temperature ]8.2 C; (35)...

Fermentation of methanol in the sheep rumen.

Sheep fed a hay-concentrate diet were adapted to pectin administration and ruminal infusion of methanol. Both treatments resulted in a strong increase in the rate of methanogenesis from methanol. Quantitative data show that methanol was exclusively converted into methane. Treatments did not influence ruminal volatile fatty acid percentages.

Effects of tallow and urea on in vitro rumen fermentation and nutrient digestion in sheep.

An in vitro study was conducted using a 4 • 2 • 2 factorial design with RAC (readily available carbohydrate) levels of 30, 40, 50 and 60%, tallow levels of 0 and 3%, and urea levels of 0 and 2%. Acetic and propionic acid production and ammonia disappearance increased as the level of RAC increased from 30 to 50%. Tallow reduced acetic acid production and increased the amount of propionic acid pr...
