Abstract This study evaluated the effects of the amount and frequency of N supplementation on intake, digestion, and urinary and blood characteristics in cattle fed low-quality tropical grass hay. Five ruminally and abomasally fistulated crossbred bulls averaging 262 ± 20 kg of body weight were used in a 5 × 5 Latin square design. The basal diet was composed of a low-quality signal grass hay (47.2 g CP/kg DM). Treatments were designed according to a 2 × 2 + 1 factorial arrangement, as follows… Expand

Investigation on daily or every three days supplementation with protein or protein and starch of cattle fed tropical forage
Abstract Effects of daily or every three days supplementation with protein or protein and starch on intake, digestion, rumen dynamics, urinary excretion characteristics, nitrogen (N) balance and,Expand
Urea supplementation in rumen and post-rumen for cattle fed a low-quality tropical forage.
TLDR
The continuous releasing of urea throughout day either in the rumen or abomasum is able to improve N accretion in the animal body, despite of mechanism responsible for that being different. Expand

Intake, digestibility, and rumen and metabolic characteristics of cattle fed low-quality tropical forage and supplemented with nitrogen and different levels of starch
TLDR
Nitrogen supplementation in cattle fed low-quality tropical forage increases nitrogen retention in the animal’s body by increasing energy availability for both rumen and animal metabolism. Expand
Intake, digestibility and rumen dynamics of neutral detergent fibre in cattle fed low-quality tropical forage and supplemented with nitrogen and/or starch
TLDR
It is observed that nitrogen supplementation increased the estimated weighted degradation rate of NDF by 14.8%, whilst starch supplementation decreased this rate by 32.5%. Expand
Nutritional Performance of Cattle Grazing during Rainy Season with Nitrogen and Starch Supplementation
TLDR
Assessment of the effects of supplementation with nitrogen and starch on the nutritional performance of grazing cattle during the rainy season found that supplementation with starch and nitrogen to beef cattle grazing during the rains can possibly improve digestion and nitrogen retention in the animal.

Daily and alternate day supplementation of urea or soybean meal to ruminants consuming low-quality cool-season forage: I—Effects on efficiency of nitrogen use and nutrient digestion
Five RambouilletPolypay wethers (5272 kg BW; Experiment 1) and 5 AngusHer- eford steers (464726 kg BW; Experiment 2) were used in two incomplete 5 � 4 Latin squares with four 18-d periods toExpand
Effects of ruminal protein degradability and frequency of supplementation on site and extent of digestion and ruminal fermentation characteristics in lambs fed low-quality forage.
TLDR
Alternate day protein supplementation with a mixture of RDP and RUP may improve digestibility in lambs consuming low-quality forage, which may be related to decreased fluctuation in ruminal ammonia concentrations as a result of greater endogenous N recycling. Expand
Effects of ruminal protein degradability and frequency of supplementation on nitrogen retention, apparent digestibility, and nutrient flux across visceral tissues in lambs fed low-quality forage.
TLDR
The provision of AA as RUP may provide a delay in ureagenesis, thus altering the timing of N recycling, and the effect of ruminal protein degradability and supplementation frequency on intake, apparent digestibility, N retention, and nutrient flux across visceral tissues of lambs fed a low-quality forage diet is suggested.

Intake and digestibility in cattle under grazing supplemented with nitrogenous compounds during dry season
The objective of this work was to evaluate the effects of supplementation with nitrogenous compounds on intake and digestibility in cattle under grazing during dry season. It was used five Holstein ×Expand
Effects of varying ruminally undegradable protein supplementation on forage digestion, nitrogen metabolism, and urea kinetics in Nellore cattle fed low-quality tropical forage.
TLDR
Overall, unsupplemented heifers had greater mobilization of AA from myofibrillar protein, which provided N for urea synthesis and subsequent recycling, and RUP, when RDP was supplied, not only increased N retention but also supported increased urea N recycling and increased ruminal microbial protein synthesis.

Influence of rumen protein degradability and supplementation frequency on performance and nitrogen use in ruminants consuming low-quality forage: cow performance and efficiency of nitrogen use in wethers.
TLDR
CP supplements consisting of 20 to 60% UIP can be effectively used by ruminants consuming low-quality forage without adversely affecting N efficiency and animal performance, even when provided as infrequently as once every 6 d. Expand
