Effects of dietary protein level on growth performance and nitrogen excretion of dairy heifers
Heifers Growth Performance Protein Nitrogen Excretion
2017/3/9
Protein supplementation is costly and can result in excess nitrogen (N) excretion. The objective of this study was to evaluate the effects of feeding different levels of dietary protein on average dai...
Effect of Dietary Concentrate:forage Ratios and Undegraded Dietary Protein on Nitrogen Balance and Urinary Excretion of Purine Derivatives in Dorper×thin-tailed Han Crossbred Lambs
Lamb Concentrate:Forage Undegraded Dietary Protein Nitrogen Balance Purine Derivatives
2016/5/16
This study aimed to investigate dietary concentrate: forage ratios (C:F) and undegraded dietary protein (UDP) on nitrogen balance and urinary excretion of purine derivatives (PD) in lambs. Four Dorper...
Effect of Microbial Phytase on Performance, Nutrient Absorption and Excretion in Weaned Pigs and Apparent Ileal Nutrient Digestibility in Growing Pigs
Novel Phytase Performance Metacarpal Bone Characteristics Apparent Ileal Digestibility Pigs
2016/5/6
Two experiments were conducted to evaluate the efficacy of Trichoderma reesei derived phytase for pigs fed diets with fixed calcium to total phosphorus ratios (1.5:1). In Exp. 1, 280 weaned pigs (init...
Modelling nitrogen excretion, elephant grass growth and animal production in a stall-feeding dairy system
Dairy heifers digestibility nitrogen excretion elephant grass
2011/1/12
This study reports on a simulation model of livestock-forage with excreted nitrogen (N) as a source of N for elephant grass (Pennisetum purpureum) growth. It is shown that nitrogen partitioning betwee...
Effects of Excess Essential Amino Acids in Low Protein Diet on Abdominal Fat Deposition and Nitrogen Excretion of the Broiler Chicks
broiler essential amino acids fat deposition nitrogen excretion
2009/7/30
Two experiments were conducted to determine whether the excess essential amino acids in low protein diets affects the performance, nitrogen excretion and abdominal fat deposition of broiler chicks. Es...
The Effects of Phytase Supplementation on Performance and Phosphorus Excretion from Broiler Chickens Fed Low Phosphorus-Containing Diets Based on Normal or Low-phytic Acid Barley
Poultry Low-phytate Barley Performance Phosphorus Excretion
2016/4/29
A total of 240 day-old broiler chicks were used to study the effects of phytase on performance and phosphorus (P) excretion from birds fed diets containing low phytate barleys formulated without inorg...
EFFECTS OF PROTEIN-XANTHOPHYLL (PX) CONCENTRATE OF ALFALFA ADDITIVE TO CRUDE PROTEIN-REDUCED DIETS ON NITROGEN EXCRETION, GROWTH PERFORMANCE AND MEAT QUALITY OF PIGS
fatteners feeding protein content
2010/12/7
The infl uence of protein-xanthophyll (PX) concentrate of alfalfa supplement to crude protein-reduced diets was examined in relation to nitrogen excretion, performance parameters and pig meat quality....

Dry Cow Lactating Cow Nitrogen Clearance Plasma Urea Nitrogen
2016/4/28
Data of 42 balance measurements from dry and lactating Holstein cows and blood and urine samples from 24 Japanese Black cows were collected to evaluate the potential for predicting urinary nitrogen (N...
Estimation of Rumen Microbial Protein Supply Using Urinary Purine Derivatives Excretion in Crossbred Calves Fed at Different Levels of Feed Intake
Crossbred Calves Levels of Feed Intake Purine Derivatives Microbial Protein Supply
2016/4/26
A study was carried out to study the response of total purine derivatives (PD) excretion in urine to determine microbial N (MN) supply at four fixed levels of feed intake (namely 95, 80, 60 and 40% of...
Effects of Supplementing with Single or Multiple Trace Minerals on Growth Performance, Fecal Mineral Excretion and Nutrient Utilization in Pullets from 1 to 18 Weeks of Age
