Effect of various doses and forms of selenium (organically bound vs. inorganic) on selected parameters of ruminal fluid and blood in sheep was evaluated. The trial was performed with 15 sheep divided into two groups. Animals from group A (n = 8) received a feeding mixture with selenomethionine, while sheep from group B (n = 7) were fed a mixture with sodium selenite. During the first 14 days, a...
The present study was conducted to determine clinico-haematobiochemical changes in ruminal acidosis-affected South Down sheep in Kashmir valley. Thirty two healthy sheep were taken as control whose parameters were compared with thirty two sheep suffering from ruminal acidosis. Clinical parameters were measured using standard techniques. Ruminal fluid, urine and blood was examined for microscopi...
The objectives of this study were to evaluate the influence of diet composition on ruminal parameters, more particularly redox potential (Eh). Four Holstein dry dairy cows, fitted with ruminal cannulas, were allocated in a 4 × 4 Latin square design. They were given four experimental hay-based diets D0, D25, D42 and D56 consisting of 0%, 25%, 42% and 56% of ground wheat and barley concentrate mi...
BACKGROUND The prevalence and the clinical consequences of subacute ruminal acidosis (SARA) in dairy cows are still poorly understood. In order to evaluate the prevalence of SARA, 26 German dairy farms were included in a field study. In each herd, between 11 and 14 lactating dairy cows were examined for their ruminal pH using rumenocentesis. Milk production data and farm management characterist...
This study was carried out to determine of the effects of monensin on ruminal fermentation parameters in Ghizel sheep. Sixteen male Ghizel sheep were used allocated in completely randomized design. The diet containing of 2.9 ME (Mcal/kg DM) and 150 g/kg DM CP was formulated based on NRC requirement consisting of 400 g kg-1DM alfalfa, 488 g kg-1 DM barley grain, 200 g kg-1 DM soybean meal, 589 g...
The objective of this study was to determine the influence of degradation characteristics of six feed supplements on ruminal volatile fatty acid and amino acid production and profile using three ruminally cannulated male sheep. The sheep were fed a concentrate to forage ratio of 35:65. The supplements came from Soybean Meal (SBM), Corn Meal (CM), Meat and Bone Meal (MBM), Feather Meal (FtM), Bl...
Effects of harvesting ruminal micro-organisms from ruminal ̄uid on patterns of gas production were investigated in experiment 1 by incubating 200 mg DM of pure cellulose, oatfeed, ryegrass, cocksfoot, wet and dry season kikuyu grasses with either diluted ruminal ̄uid or harvested ruminal bacteria. Gas production degradability parameters obtained from ®tting the data to the model Gas B(1ÿ expÿ...
Our objective was to study the effect of different roughage sources produced in a tropical environment on intake, digestibility, and ruminal parameters of crossbred bulls. Five rumen-fistulated 30-mo-old Holstein × Bos indicus bulls (average BW =459 ± 32.5 kg) were utilized in a 5 × 5 randomized Latin square design. The experiment consisted of five 19-d experimental periods (10 d for adaptation...
