Effects of nitrogen fertilizer and harvesting stage on photosynthetic pigments and phytol contents of Italian ryegrass silage.

This study aimed to investigate the effects of nitrogen (N) fertilizer application and harvesting stage on the contents of chlorophyll, phytol and carotenoids (β-carotene and lutein) in Italian ryegrass herbage before and after ensiling, and the extent of phytol preservation after ensiling. Three rates of N fertilizer (0, 60 and 120 kg N/ha) were applied by top-dressing as an additional fertilizer. The herbage harvested at booting stage (27 weeks of age) or heading stage (29 weeks of age) were wilted for 1 day, then ensiled for 60 days using a small-scale pouch system.

Probiotics as an environment-friendly approach to enhance red sea bream, Pagrus major growth, immune response and oxidative status.

A usual strategy in modern aquaculture to combat production bottlenecks associated with intensification is preventive health care through the use of consumer and environment-friendly alternatives including probiotics. The current study evaluates the influence of Lactobacillus rhamnosus (LR), a lyophilized probiotic bacterium, on health status and performance of red sea bream (Pagrus major). Probiotics were incorporated in the diets at four different concentrations: 0 (control diet, LR0), 10(2) (LR1), 10(4) (LR2) and 10(6) (LR3) cells g(-1) and diets were administered to the fish for a period of 8 weeks.

Physiological response, blood chemistry profile and mucus secretion of red sea bream (Pagrus major) fed diets supplemented with Lactobacillus rhamnosus under low salinity stress.

Environmental stressors caused by inadequate aquaculture management strategies suppress the immune response of fish and make them more susceptible to diseases. Therefore, efforts have been made to relieve stress in fish by using various functional feed additives in the diet, including probiotics. The present work evaluates the effects of Lactobacillus rhamnosus (LR) on physiological stress response, blood chemistry and mucus secretion of red sea bream (Pagrus major) under low salinity stress.

Metabolomic profiling reveals differential effects of glucagon-like peptide-1 and insulin on nutrient partitioning in ovine liver.

This study was conducted to identify the insulin-independent actions of glucagon-like peptide-1 (GLP-1 (7-36 amide)) in partitioning nutrient metabolism in ovine liver. Four Suffolk wethers (60.0 ± 6.

Insulin-independent actions of glucagon-like peptide-1 in wethers.

Insulin-independent actions of glucagon-like peptide-1 (GLP-1) are not yet clear in ruminants. Four Suffolk mature wethers (60.0 ± 6.

The effect of dietary ratios of corn silage and alfalfa hay on carbohydrate digestion and retention time of feed particles in the gastrointestinal tract of steers.

Four Holstein steers fitted with duodenal cannula were used in a 4 x 4 Latin square design to investigate the effect of the combination of corn silage (CS) and alfalfa hay (AH) in different ratios on the ruminal and intestinal digestion of carbohydrates and feed particle passage rate. Steers were fed mixed diets containing both CS and AH in ratios of 80:20, 60:40, 40:60 and 20:80 on a dry matter basis at 95% of ad libitum feed intake. The increase of AH proportion in diets increased dry matter intake and ruminal digestion of dry matter, non-fiber carbohydrate, neutral and acid detergent fiber linearly.
