The objective of this meta-analysis was to quantitatively summarize variations in urea kinetics related ruminant species, diet composition, and ruminal fermentation. A database 31 studies measuring recycling were used derive 2 sets linear mixed-effects regression models. Study as a random intercept regressions weighted by 1 divided the standard error mean observation. Models compared, when appr...

Abstract The impacts of future climate change on the watershed streamflow and total dissolved nitrogen (TDN) fluxes upstream Danjiang River were estimated. newest shared socioeconomic pathways (SSP) in CMIP6 used as a scenario. ensembles downscaled GCM outputs from WorldClim information. A combined modeling approach is proposed, including Long Ashton Research Station Weather Generator (LARS-WG)...

T HE experiment involved 48 pairs of male Holstein fraternal twin calves. Two methods of raising calves were contrasted: (A) High fat (20%) and protein (20%) vealer ration fed from 3 days of age to a market weight of 128 kilograms. (B) The same vealer was fed up to a live weight of 56.7 kg, followed by pelleted grain mixture fed ad libitum and hay offered to a maximum of 0.9 kg per day. Twin pa...

Elements of forage testing as it relates to markets include 1) Standardization of Sampling, 2) Standardization of between-lab variation, and 3) Standardization of what is analyzed. None of these elements can be ignored. While the current ‘fiber based’ system of utilizing Relative Feed Value and TDN has been useful, incorporation of more dynamic analyses are needed. A ‘core alfalfa test’ consist...

[1] Storm event patterns of dissolved organic nitrogen (DON) were studied for multiple events across four catchments (1.6–696 ha) in a forested, glaciated watershed in western New York State. Highest concentrations of DON in the watershed were recorded for litter leachate followed by throughfall. Storm event concentrations of DON consistently peaked at or before peak discharge while dissolved o...

sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. buffaloes in the first group were fed the control ration (r1) consisted of dm basis of 60% concentrate feed mixture (cfm)+20% rice straw (rs)+20% berseem hay (bh), while in the other groups the rations consisted of dm basis of 40% cfm+20% rs+40...
