Effects of replacing canola meal with dehulled hemp in the diet lactating dairy cows on dry matter intake (DMI), milk production, fatty acid profile, blood metabolites, total-tract nutrient digestibilities, and transfer cannabinoids were determined 12 lactating, non-pregnant Holstein cows. These used a 3 × Latin Square design 3, 3-wk experimental periods, consisting 2 wk adaptation 1 sampling. ...

the aim of this study was to investigate the effect of feeding of  steeped barley grain with lactic acid (la) and citric acid (ca) on dry matter intake, feeding behavior, apparent nutrients digestibility, rumen ph and milk production. eight early lactating holstein cows in the second parities were used in 4×4 latin square change- over design. treatments  consisted of basis diet containing 1) dr...

1. The metabolism of acetate, glucose and D(-)-3-hydroxybutyrate was studied in lactating and non-lactating sheep in vivo. Special consideration was given to the utilization by hind-limb muscle in both groups of sheep and the uptake of nutrients by the lactating mammary gland was also measured. 2. The entry of acetate into the circulation (mmol/h per kg body-weight) was similar in all experimen...

Forages are vital in maintaining the dietary structures of ruminants, and reducing their costs is important for improving dairy production efficiency. Thus, this study investigated effects forage types on dry matter intake, production, rumen fermentation, microbial profile peak-lactating cows. Eight cows (600 ± 25 kg) with days milk (60 10 days) were assigned to four groups using a replicated 4...

There are approximately 2.5 million dairy cows in California. Emission inventories list dairy cows and their manure as the major source of regional air pollutants, but data on their actual emissions remain sparse, particularly for smog-forming volatile organic compounds (VOCs) and greenhouse gases (GHGs). We report measurements of alcohols, volatile fatty acids, phenols, and methane (CH4) emitt...
