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...
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...
EFFECTS OF PROTEIN-XANTHOPHYLL (PX) CONCENTRATE OF ALFALFA ADDITIVE TO CRUDE PROTEIN-REDUCED DIETS ON NITROGEN EXCRETION, GROWTH PERFORMANCE AND MEAT QUALITY OF PIGS
