This experiment was conducted to determine the effect of using L-threonine and reducing dietary levels of crude protein (CP) on egg production criteria in layers. Three hundred of Hy-Line W36 laying hens were used in this experiment. This experiment consisted of three experimental treatments with five replications in each. Experimental treatments included 3 diets with different levels of CP whi...

The objective of this study was to investigate the effects of l-carnitine and/or maize distillers dried grains with solubles (DDGS) in diets of gestating and lactating sows on the intestinal barrier functions of their offspring. The experiment was designed as a 2×2 factorial with two dietary treatments (soyabean meal v. DDGS) and two l-carnitine levels (0 v. 100 mg/kg in gestating diets and 0 v...

the effects of different dietary levels of soybean oil (2, 4 and 6%) and probiotic primalac (0, 0.1 and 0.15 %) were investigated on performance and immune system of broiler chickens from day one to day 42 of age. for this purpose, five hundred and forty day-old male broiler chicks (cobb) in 9 groups of 60 each were used. the birds of each group were divided into 6 pens of 10 birds. the experim...

Cinnamon essential oils (EOs) are widely known for their pharmaceutical properties; however, studies investigating the use of these EOs in aquaculture scarce. The aims this study were to evaluate anesthetic effect bathing silver catfish (Rhamdia quelen) with Cinnamomum cassia EO (CCEO) and its nanoemulsion (NCCEO); growth-promoting antioxidant effects dietary supplementation CCEO catfish; vitro...

Currently, research on athletes focuses on optimizing the nutritional status in order to adjust their minerals requirements. This study was designed to evaluate baseline nutritional status and the effect of a nutritional intervention based on magnesium (Mg) supplementation, on plasma and erythrocyte concentrations of Mg and zinc (Zn), and their relationship with training load. We analyzed train...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...

Background High-performance, adult athletes consume dietary supplements to increase energy, maintain health or prevent nutritional deficiencies and improve exercise recovery; however, dietary supplementation patterns of young, Canadian athletes remain undetermined. Purpose: 1) Determine the types and frequency of dietary supplement use in young athletes. 2) Determine preferred means of educatio...

The present study was carried out to evaluate the influence of increasing amounts of dietary polyunsaturated fatty acids (PUFA) and alpha-tocopheryl acetate (alpha-TA) supplementation on lipid oxidation of raw and cooked thigh meat stored under refrigeration. One hundred ninety-two female, 1-d-old, broiler chickens were randomly distributed into 16 experimental treatments resuIting from the com...

Current interest in preventive nutritional supplementation strategies during the reproductive cycle in developed countries focuses mainly on iron and folic acid. Iron deficiency is the most common cause of anaemia. Inadequate iron nutrition is mainly a problem in developing countries but it also seems to affect a large proportion of pregnant women in the industrialised world. There is no chance...

The experiment was conducted to investigate the effects of dietary supplementation of fulvic acid on lipid metabolism of finishing pigs. One hundred eighty crossbred barrows (Landrace × Yorkshire, 60 ± 2.5 kg) were randomly allotted to 5 dietary treatments (36 pigs/treatment) and fed a basal diet supplemented with 0, 0.2%, 0.4%, 0.6%, and 0.8% fulvic acid for 42 d. Thirty pigs (6 pigs/treatment...
