One approach to improving efficiency of protein and nitrogen use for optimal productivity in dairy heifers is to provide adequate levels of protein with differing rumen degradabilities. The objective of this experiment was to determine effects of manipulating RDP in diets of dairy heifers precision fed low- and high-quality forage. Eight rumen-cannulated Holstein heifers (448 ± 19 kg BW) were randomly used and assigned to an 85% forage diet with 2 forage qualities, low quality (LQ, 48% NDF) and… Expand
Precision-feeding dairy heifers a high rumen-undegradable protein diet with different proportions of dietary fiber and forage-to-concentrate ratios.
TLDR
RUP supplementation is a practical method for reestablishing optimal ruminal N balance in the event of increased dietary fiber through forage inclusion in precision-fed dairy heifer diets. Expand
Comparison of diet digestibility, rumen fermentation, rumen rate of passage, and feed efficiency in dairy heifers fed ad-libitum versus precision diets with low and high quality forages
ABSTRACT This study compared ad-libitum versus precision-fed diets with 2 forages and different levels of neutral detergent fibre (NDF) to evaluate rumen fermentation, diet digestibility, feedExpand
Short communication: Glucose kinetics in dairy heifers limit-fed a low- or high-forage ration at 4 levels of nitrogen intake.
TLDR
The response to an intravenous glucose bolus differs in dairy heifers fed diets differing in N intake, whereas forage level did not affect this response, and this should be considered when formulating rations for low N intake by replacing high-N for high-starch feedstuffs when limit-feeding dairyheifers.

Effect of supplemental dietary slow-release urea on growth performance and physiological status of dairy heifers.
TLDR
It was concluded that the addition of urea at a level of 1.0%-1.5% urea resulted in the highest ADG, with no negative effects on rumen fermentation and health status of the calves. Expand
Effects of polymer coated slow-release urea on ruminal fermentation and nutrient total tract digestion of beef steers
The objective of this study was to evaluate the effects of polymer coated slow-release urea (SRU) in high-forage diets of beef steers on nutrient intake and digestibility, ruminal fermentation,Expand
Symposium review: Strategies to improve the efficiency and profitability of heifer raising.
TLDR
Regional Research Project NC-2042 has an effect on heifer feeding, resulting in new information that can aid in the sustainability of dairy farms, and this review will focus on the area of postweaned heifer nutrition. Expand
Effect of soybean meal replacement by slow-release urea on ruminal parameter, blood metabolites, and microbial protein synthesis in Zel ram
The objective of this study was to determine the effect of soybean meal replacement by slow-release urea on feed intake, ruminal parameters, blood metabolites, dry matter, nutrients digestion, andExpand
Characterization and comparison of the temporal dynamics of ruminal bacterial microbiota colonizing rice straw and alfalfa hay within ruminants.
TLDR
The metagenomes predicted by phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) revealed that the forage types significantly affected 21 metabolic pathways identified in the Kyoto Encyclopedia of Genes and Genomes, and 33 were significantly changed over time.

Bacterial colonisation of reeds and cottonseed hulls in the rumen of Tarim red deer (Cervus elaphus yarkandensis)
TLDR
The dynamics of colonisation by bacterial communities attached to reeds and cottonseed hulls in the rumen of Tarim red deer are investigated and Prevotella1 and Rikenellaceae RC9 were the most abundant taxa in both the reed and Cottonseed hull groups at various times, indicating a key role of these organisms in rumen fermentation in TarimRed deer.

Digestion and nitrogen utilization in dairy heifers limit-fed a low or high forage ration at four levels of nitrogen intake.
TLDR
It is concluded that increasing N intake increases the digestibility of OM, the magnitude of which depends on the level of dietary forage provided. Expand
Rumen digestion and nutritional efficiency of dairy heifers limit-fed a high forage ration to four levels of dry matter intake.
TLDR
It can be concluded that when dairy heifers are limit-fed a high forage diet, the efficiency of nutrient utilization is increased as intake decreases, but reducing DMI below 1.50% BW reduced efficiency. Expand
Effects of feeding different levels of dietary fiber through the addition of corn stover on nutrient utilization of dairy heifers precision-fed high and low concentrate diets.
TLDR
In conclusion, increasing dietary fiber through CST decreased DMD and organic matter digestibility linearly, whereas NDF and ADF digestibility were maximized when 20% CST was added to HC and LC diets. Expand
Nutrient utilization of differing forage-to-concentrate ratios by growing Holstein heifers.
TLDR
Feeding low-forage, high-concentrate diets to growing dairy heifers at restricted intakes, although more highly digestible, resulted in few significant differences in rumen fermentation patterns and lower fecal output. Expand
The effects of controlled feeding of a high-forage or high-concentrate ration on heifer growth and first-lactation milk production.
TLDR
Monitoring growth and first-lactation milk production in dairy heifers fed a high-forage or high-concentrate ration for similar levels of average daily gain before puberty concluded that controlled feeding of HC during the rearing period may allow for improved growth efficiency for dairy heIFers while maintaining future productivity.

Rumen fermentation pattern of dairy heifers fed restricted amounts of low, medium, and high concentrate diets without and with yeast culture☆
TLDR
Investigation of the ruminal fermentation and in situ digestibility of diets with 3 different levels of forage to concentrate fed at restricted intake without and with YC addition of dairy heifers found no change in digestibility. Expand
Effect of dietary concentrate on rumen fermentation, digestibility, and nitrogen losses in dairy cows.
TLDR
Increased concentrate proportion in the diet of dairy cows resulted in reduced ruminal ammonia concentration and enhanced ammonia utilization for milk protein synthesis, however, these effects did not result in reduced urinary N losses and only marginally improved milk N efficiency. Expand

Estimates of rumen microbial nitrogen (MN) production derived from duodenal flow measurements with those obtained from urinary purine derivatives (PD) excretion are compared. Expand
