The Effect of Monensin Supplementation on Ruminal Fermentation Parameters of Sheep
نویسنده
چکیده
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 kg-1 DM, corn grain and 20 g kg-1 DM limestone containing predicted metabolizable energy 2.9 Mcal kg-1 DM and containing crude protein 150 g kg-1 DM. The treatments containing different level of ionophores (20 ppm, 25 ppm, 30 ppm and 35 ppm). The experiment period was 21 days. The rumen fluid was collected using stomach tube at 2 and 4 h after morning feeding. The floatation and sedimentation time, methylene blue reduction time, pH, total ammonia nitrogen and total VFA in ruminal samples were determined. The ruminal pH, total VFA, sedimentation and floatation time and methylene reduction time were not significant differences. The effect of monensin on ruminal ammonia concentration was significant difference (P<0.05). The results showed that the monensin had not effect on ruminal parameters except of ruminal ammonia-N resulted low proteolytic bacteria activity.

Short communication Effect of a yeast culture (Saccharomyces cerevisiae) and monensin on ruminal fermentation and digestion in sheep
A metabolism trial was conducted to evaluate the effects of supplying a yeast culture containing Saccharomyces cerevisiae (Levucell) and monensin to sheep, on ruminal fermentation and digestibility of diets. Four Suffolk sheep (30 kg BW) with ruminal cannula were used in a Latin Square design, where treatments were control (C), 1 g/day of Levucell (L, 20 10 CFU/g), 25 mg/ day of monensin (M) an...

An in vitro gas production technique was used to evaluate the effects of different adsorbents on the gas production parameters of lead-exposed diet. Ruminal fluid, obtained from fistulated sheep (3-4 years of age and 40±5 kg BW), and experimental diets samples, 200 ± 0.2 mg DM, were incubated in 100 mL glass bottles. To each bottle, one of the following treatments was applied: 1) control (no Pb...

The aim of this study was to evaluate the effect of fat supplementation for enhancing milk conjugated linoleic acid (CLA) in early lactation without affecting ruminal fermentation. 24 Holstein dairy cows were assigned to a completely randomized design employing a 2 × 4 factorial arrangement. Factors were particle size (15 and 25 mm) and two different sources of alfalfa supplemented with and wit...
