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 measures, starter digestibility, starter intake, blood metabolites and rumen metabolites of nursing calves were assessed in weeks 4, 8 and 12 to assess rumen development and find the optimum method of wheat processing for calves. Calves were weaned...

in order to evaluate the quantitative factors in fox tail millet (setaria italica l.) under three stages of growth, an experiment was conducted in birjand during spring and summer of 2010. the preliminary objective was evaluation of fox tail physiological characteristics on animals that feed them. planting of foxtail millet was performed according to local practices and endemic acknowledge. sam...

The objective was to determine the effects of ground wheat grain (GW) inclusion rate, grinding extent (GE), and their interaction on lactating cow performance. Eight midlactation cows in 3 × 4 m individual boxes were used in a 4 × 4 replicated Latin square design study with 4 21 d periods. GW was fed at either 10% or 20% of diet dry matter (DM), as either finer or coarser particles. DM intake i...

The objective of this study was to determine the effects of physically effective neutral detergent fiber (peNDF) content in total mixed ration (TMR) on dry matter intake, digestibility, and chewing activity in fattening Hanwoo (Bos taurus coreanae) heifers. The experiment was designed as a replicated 3×3 Latin square using 12 heifers. Fattening heifers were offered one of three diets [high (T1)...

This study evaluated the effects of gradual replacement barley with oats on enteric CH4 emissions, rumen fermentation, diet digestibility, milk production, and energy utilization in dairy cows fed a grass silage-based diet. Sixteen lactating Nordic Red received total mixed ration [58:42 forage:concentrate dry matter (DM) basis]. Grass silage (Phleum pratense) was sole forage canola meal (10% DM...

This study was conducted to investigate the effects of different levels of peptide supplementation on rumen fermentation pattern, digestibility and microbial protein synthesis. Three rumen-cannulated Holstein dairy cows were used in a 3 × 3 Latin square experiment within 21 days period. The ruminal infusion of sodium caseinate (CN) was 0 (control), 50 and 100 g/d. Dry matter intake, milk yield ...

BACKGROUND Much of the recent research in companion animal nutrition has focussed on understanding the role of diet on faecal microbiota composition. To date, diet-induced changes in faecal microbiota observed in humans and rodents have been extrapolated to pets in spite of their very different dietary and metabolic requirements. This lack of direct evidence means that the mechanisms by which m...

Several studies have reported data on comparisons between two methods: the total collection of feces and the internal markers method. The aim of this study was to assess the apparent digestibility of two concentrates and to compare the apparent digestion coefficients using the total collection of feces and acid-insoluble ash (AIA) as the internal marker method. In 2009, six adult geldings aged ...
