Prediction of CP and starch concentrations in ruminal in situ studies and ruminal degradation of cereal grains using NIRS

Animal, 2018
Ruminal in situ incubations are widely used to assess the nutritional value of feedstuffs for ruminants. In in situ methods, feed samples are ruminally incubated in indigestible bags over a predefined timespan and the disappearance of nutrients from the ...

Effect of dehydration on ruminal degradability of lucerne [PDF]

Annales de Zootechnie, 2000
The effects of industrial dehydration and a subsequent compression at high pressures on rumen degradability of lucerne were determined in 3 samples obtained at harvest or after the process of dehydration and compression of this forage. Rumen degradability of dry matter (DM) and nitrogen (N) was determined by the nylon bag technique in 3 ruminally ...

Chemical composition and ruminal degradation kinetics of crude protein and amino acids, and intestinal digestibility of amino acids from tropical forages

Revista Brasileira de Zootecnia, 2012
The objective of this research was to determine the chemical composition and ruminal degradation of the crude protein (CP), total and individual amino acids of leaves from tropical forages: perennial soybean (Neonotonia wightii), cassava (Manihot ...

Ruminal and post-ruminal phytate degradation of diets containing rapeseed meal or soybean meal

Archives of Animal Nutrition, 2022
This study aimed to investigate ruminal and post-ruminal degradation of phytic acid (InsP6) in diets containing either rapeseed meal (RSM) or soybean meal (SBM). In Experiment 1, the effective degradability of crude protein (CPED) and InsP6 (InsP6ED) was evaluated by incubating RSM and SBM in situ in three rumen-fistulated lactating Jersey cows for 2 ...

Can the post-ruminal urea release impact liver metabolism, and nutritional status of beef cows at late gestation?

PLoS ONE, 2023
We aimed to evaluate the effects of post-ruminal supply of urea (PRU) on nutritional status, and liver metabolism of pregnant beef cows during late gestation.

Intake, Digestibility, and Ruminal Degradability of Shredded Hay

Journal of Dairy Science, 1994
Thirty-two Outaouais intact male lambs averaging 39.1 kg were assigned randomly to a 2 x 2 factorial arrangement of treatments consisting of two forages and two methods of harvesting to determine intake and digestibility. The four treatments fed during the experiment consisted of alfalfa and timothy hays harvested with either a prototype mat maker or a

The Efficacy of Food‐Grade Substances to Protect Dietary Glutamine From Ruminal Degradation

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to investigate the use of four, low cost, food‐grade substances to protect glutamine from microbial degradation in vitro, and subsequently validate their efficacy in vivo. Two in vitro trials were conducted using 250 mL bottles replicated in triplicate to test beeswax‐, paraffin wax‐, zein‐, and rice bran wax ...

Loss of Stability for Blood Urea Nitrogen in Cattle Serum Samples Stored for 3 and 6 Months at −20°C and −80°C

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background Biological samples are stored for delayed or add‐on analyses. However, storage conditions, including time and temperature, can affect the stability of measurands in the samples. Objectives To assess the stability of blood urea nitrogen (BUN) in cattle serum samples.
