Three experiments were conducted to investigate interactions between acetate and glucose metabolism in sheep fed on roughage-based diets, and to establish whether the clearance rate of an intravenous acetate load would provide a valid index of the dietary acetate:glucogenic precursors ratio. In Expt 1 lambs were fed on a basal diet of wheat straw and supplemented with propionate and protein. Bo...

background: in recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. objectives: this study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing chal lambs. methods: eighteen male ...

tetranychus urticae koch is an injurious pest of, fruit crops, crop plants as well as ornamental plants worldwide. the high reproductive potential of t. urticae and its fairly short life cycle along with the frequent application of acaricides usually required to maintain t. urticae populations below economic thresholds, facilitates the pest's resistance to acaricides, and consequently cont...

Cattle grazing dormant western rangelands may have a high ruminal acetate to propionate ratio (A:P) and may have low tissue clearance of acetate. Increasing propionate production could shift this ratio and improve animal performance. In Exp. 1, the effect of Propionibacterium acidipropionici P169 (PA) on forage digestibility and VFA production was evaluated in vitro using 2 substrates: 100% dor...

The objective of these experiments was to determine if a change in the ratio of acetate to propionate (A:P ratio) in hepatic portal blood, draining the gastrointestinal tract, can alter the metabolism of progesterone by the liver. Experiment 1; 4 crossbred, ewe lambs (BW 45.5 + 2.5 kg) were fed for maintenance and given a once daily oral bolus (0.146 Mcal/d) of acetate (0.7 moles) or propionate...

Feed intake and nutrient digestibility, rumen fermentation profiles, milk yield compositions of lactating dairy cows fed with Flemingia macrophylla pellet (FMP) were evaluated. Four crossbred in early lactation randomly allocated into a 2×2 factorial arrangement 4×4 Latin square design (LSD). The first factor was protein level concentrate mixtures consisted two levels, i.e., 14% 16%. second sup...

This study was designed to investigate the effect of grape pomace powder (GPP), mangosteen peel powder (MPP) and monensin on feed intake, nutrients digestibility, microorganisms, rumen fermentation characteristic, microbial protein synthesis and nitrogen balance in dairy steers. Four, rumen fistulated dairy steers with initial body weight (BW) of 220±15 kg were randomly assigned according to a ...

Two trials were conducted to investigate the effects of disodium fumarate (DSF; 0.00, 8.00, 10.00 and 12.00 mM) and thyme essential oil (TEO; 0.00, 100.00, 200.00, 300.00 and 400.00 µL L-1) solely and simultaneously (10.00 mM DSF along with 100.00, 200.00, 300.00 and 400 µL L-1 TEO) on in vitro ruminal fermentation of a 50:50 alfalfa hay to concentrate diet. The D...
