Caprylic acid (CA) and Yucca schidigera (YS) extract have many functional and nutritional properties that may have applications in animal nutrition. These beneficial effects include improvement of growth performance, immunity and anti-microbial activity. This study was conducted to assess the effects of dietary supplementation with CA and YS extract on growth performance, relative organ weight,...

BACKGROUND Broiler chickens are compulsive feeders that become obese as juveniles and are thus a unique model for metabolic disorders in humans. However, little is known about the relationship between dietary composition, fasting and refeeding and adipose tissue physiology in chicks. Our objective was to determine how dietary macronutrient composition and fasting and refeeding affect chick adip...

Evaluate the interaction of dietary betaine and carnitine on subsequent circulating metabolomics immune cell response. This study was a complete factorial with or without added (276 5600 mg/kg as fed analyzed) 2 levels (26 382 analyzed). Thirty two dogs (range 2–11) were used. All assigned to one four treatment foods: control, control plus betaine, carnitine. foods for ninety days. Blood analys...

Yellow discoloration often develops in rice kernels during post-harvest storage, due possibly to fungal activity. The present study examined the changes in nutrient composition taking place during yellowing of rice, and the effects of feeding rats and broiler chicks on a moderately yellow rice at 600 g/kg diet. Nitrogen content was found to be higher in rice grains that had become more yellow, ...

The role of nutritional substances in the management of insulin resistance is of interest. The present study was aimed to explore the effect of administration of L-carnitine on lipid metabolism and oxidative stress in a high fructose-fed, hyperlipidemic, insulin resistant rat model. Rats fed fructose showed hyperlipidemia, significant alterations in lipoprotein profile, and accumulation of trig...

Lysine (Lys) and Methionine (Met) as two primary essential amino acids and precursors of carnitine biosynthesis are involved in most of economical traits function in domestic animals. We assessed the impact of dietary Lys and Met on the performance, lipid redistribution, intramuscular fat, carcass quality and especially phenotypic correlations among some studied parameters in broiler chickens. ...

This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

The aim of this study was to determine whether the age of broilers can influence their response to tannin-rich diets. A total of 340 one-day-old mixed sex Ross 308 broiler chicks were distributed among five experimental groups with four replicates and 17 birds each in a completely randomized design. A high-tannin feedstuff, Oak acorn, was included into diets (at a level of 25%) and fed to birds...

Guanidinoacetic acid is formed from Arg and is the immediate precursor to creatine (Cre). A study was conducted to determine the ability for GAA to spare Arg in broiler chicks fed an Arg-deficient practical diet. A common basal diet (0.84% digestible Arg) was supplemented with combinations of Arg (0 or 0.16%) and GAA (0, 0.06, or 0.12%) to form a 2 × 3 factorial arrangement of dietary treatment...
