The addition of microbial inoculant did not improve DM recovery, fermentation process, and did not influenced beef cattle nutrient intake and performance.
Four Holstein steers (339 ± 10 kg initial BW) fitted with ruminal and duodenal cannulae were used in a 4 × 4 Latin square design to evaluate the effects of flax inclusion in diets for growing and finishing cattle on intake, ruminal fermentation, and site of digestion.
The objective of this study was to determine the influence of increasing doses of CHI for grazing cattle on nutrient intake and total apparent digestibility, ruminal fermentation parameters, microbial protein synthesis, nitrogen utilization, and urea and creatinine metabolism.
Our results suggest that high levels of citrus pulp to beef cattle can lower forage intake, but increase total energy intake.
Soybean hulls may be an effective supplement for increasing average daily gains without decreasing hay intake for cattle fed mature bahiagrass hay, and for molasses to be effective in growing cattle, it should be fortified with a nitrogen source such as urea.
Alkanes can be used to estimate intake in cattle.
It is recommended to include 418 g kg−1 of spineless cactus on a DM basis as a replacement of Tifton hay in the diet of cattle to maximize energy intake.
Previous research shows that IGF-1 has favourable correlations with a number of important traits in beef cattle including residual feed intake (RFI), carcass fatness, average daily gain, live weight and carcass weight.
These studies suggest that one QTL associated with an overdominance effect on growth or feed intake in cattle is located within or adjacent to the GHSR1a region.
Consequently, mechanisms other than glucose signaling must control feed intake in cattle and we identify a role for ACSL6 in this process.
