"Impact of Chinese royal jelly on performance, behaviour and some blood parameters in broilers reared under high stocking density."
OBJECTIVE: This experiment was conducted to assess the use of Chinese Royal Jelly (RJ) over a 6 weeks period on performance, behaviour and BLOOD PARAMETERS of broilers. METHODOLOGY:Approximalty,180 one-day-old Ross broiler chicks were randomly assigned to six treatment groups as follows; Group 1: Control (LSD; 8 birds, per meter square and no supplementation), Group 2: High stocking density (HSD; 16 ... إقراء المزيد

"Effect of 1-Day-Old Body Weight on Subsequent Performance, Behavior and Egg Quality Traits in Laying Hyline-White Hens Kept in Cages ".
One of the main goals of chicken breeders is to improve laying performance and therefore, reliable predictors are required. In this study, the effect of 1-day-old chicks body weight (BW) on the laying performance, behavior and egg quality traits of laying Hyline-white hens was examined from 20-40 weeks. A total of 180 chicks were separated into three categories based on ... إقراء المزيد

"Desensitization of Nociceptive and Serotonergic Thermoregulatory Responses by Capsaicin in Chicken: Role of Capsaicin-Sensitive Subtype-1 Vanilloid Receptor-Independent Mechanisms"
BACKGROUND: It is well known that chicken is insensitive to pain burning sensation of capsaicin (main ingredient of hot chilli peppers) this may be due to insensitivity of transient receptors membrane potential of vanilloid subtype-1 (TRPV1) of chicken to capsaicin. So actions of capsaicin in chicken could be mediated through TRPV1-independent pathways. Serotonin (5-HT) acts as an excitatory transmitter in ... إقراء المزيد

Extract of grains of paradise and its active principle 6-paradol trigger thermogenesis of brown adipose tissue in rats
Grains of paradise (GP) is a species of the ginger family, _Zingiberaceae_, extracts of which have a pungent, peppery taste due to an aromatic ketone, 6-paradol. The aim of this study was to explore the thermogenic effects of GP extracts and of 6-paradol. Efferent discharges from sympathetic nerves entering the interscapular brown adipose tissue were recorded. Intragastric injection of a ... إقراء المزيد
