The objective of this study was to investigate the effect of banana flower powder (BAFLOP) supplementation on gas production kinetics and rumen fermentation efficiency in in vitro incubation with different ratios of roughage to concentrate in swamp buffalo and cattle rumen fluid. Two male, rumen fistulated dairy steers and swamp buffaloes were used as rumen fluid donors. The treatments were arr...
keyvan karkoodi*, saeed khalajzadeh department of animal science, saveh branch, islamic azad university, saveh, iran *corresponding author's e-mail: [email protected] received: 12 august 2013 accepted: 21 november 2013 abstract thirty neonatal male holstein calves fed by starter diets containing ground wheat (gw) or dry-rolled wheat (drw) to 12 weeks of age. skeletal growth ...
Gross Pathology: Variably sized ulcers (3-10 mm) were present on the nares, tongue, larynx, and rumen. Through the cecum and proximal colon were segmental areas of necrosis and hemorrhage with ulcerated areas covered by a fibrinonecrotic membrane. Ileocolic and cecocolic lymph nodes were markedly enlarged, edematous and hemorrhagic. Numerous petechiae were noted in both renal cortices. Although...
Abstract Background and objective: Bioindicators of drinking water are always influenced by physical and chemical factors such as turbidity and chlorine. Considering the assessment of drinking water quality is based on residual chlorine, E.coli, heterotrophic bacteria and turbidity. We aimed to evaluate the effect of pH, chlorine residual and turbidity on the microbial ...
in this experiment, different doses of zataria multiflora (zm) and eucalyptus globolus (eg) essential oils (eos) (0, 100, 250, 500, 750 and 1000 µg/ml) and a mixture of them were added to alfalfa hay incubated with buffered rumen liquor of merghoz goat to assess in vitro gas production, rumen fermentation and protozoa population. in all treatments the asymptotic gas volume (b) and the rate cons...
the present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. in the in situ experiment dacron bags were filled with 3 g alfalfa hay. this was incubated in the rumen of three ruminally cannulated ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...
This experiment was carried out to study the effects of Lactic Acid Bacteria (LAB) and urea on chemical composition, nutritive value and rumen fermentation characteristics of whole-crop barley. In a completely randomized design with cross over arrangement, 4 Suffolk male lambs were used. Whole-crop barley was either treated with LAB solution (35% dry matter) at the rate of 2 L/ton herbage fresh...
One of the largest challenges for the dairy industry is to provide cows with a diet which is highly energetic but does not negatively affect their rumens' functions. In highly productive dairy cows, feeding diets rich in readily fermentable carbohydrates provides energy precursors needed for maximum milk production, but simultaneously decreases ruminal pH, leading to a widespread prevalence of ...
Eight ruminally fistulated steers were utilized to evaluate the effects of amount of dried distillers grains (DDG) supplementation on forage dry matter intake (DMI), digestibility, and rumen parameters in steers consuming bermudagrass round bale silage (RBS). Treatments consisted of RBS only or RBS plus daily supplementation of DDG at 0.33, 0.66, or 1.0% of bodyweight (BW). There was quadratic ...
The cellulolytic activity of rumen contents was assayed by measuring losses in weight and tensile strength of cotton yarn incubated in rumen contents in the presence of dietary additives (barley, tallow) and at different pH values. The addition of barley depressed cellulolysis and the titer of filter paper-degrading bacteria only if the pH was allowed to fall. Lowering the pH from 7.0 to 6.0 by...
