Effect of Guanidinoacetic Acid Supplementation on Growth Performance and Gut Morpholog yin Broiler Chickens
This study evaluates the effects of different levels of guanidinoacetic acid (GAA) supplement on growth performance and gut morphology in broilers (Ross 308 strain) raised at high altitude (2100 m). A total of 300 one-day-old male broiler chicks (Ross 308 strain) were used in a completely randomized design with five treatments and four replicate pens of 15 birds in each. Five dietary treatments...
متن کاملBehavioural, brain and cardiac responses to hypobaric hypoxia in broiler chickens.
A novel approach to pre-slaughter stunning of chickens has been developed in which birds are rendered unconscious by progressive hypobaric hypoxia. Termed Low Atmospheric Pressure Stunning (LAPS), this approach involves application of gradual decompression lasting 280s according to a prescribed curve. We examined responses to LAPS by recording behaviour, electroencephalogram (EEG) and electroca...
متن کاملEffects of Zinc Oxide Nanoparticles Supplementation on Mortality due to Ascites and Performance Growth in Broiler Chickens
Six hundred 1-d old male broilers (Ross 308) were assigned into four experimental groups; each was composed of 5replications of 30 birds including control (0), 10, 20 and 40 mg/kg nano-ZnO in the basal diets. Birds were exposed to low ambient temperature (15 to 18 ˚C) to induce ascites. Blood parameters including; activity of aspartate transferase (AST), alanine transferase (ALT), lactate dehyd...
متن کاملRelative effectiveness of herbal methionine compared to DLmethionine on growth, performance and carcass responses basis in broiler chickens
BACKGROUND: The degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. OBJECTIVES: Relative effectiveness of herbalmethionine (H-Met®) compared to DL-methionine (DL-Met)was investigated in this experiment. METHODS: Exponentialregression analysis was used to determine bioefficacy of H-Met®based on body weight gain, feed intake and feed c...
متن کاملDietary L-carnitine Improves Pulmonary Hypertensive Response in Broiler Chickens Subjected to Hypobaric Hypoxia
The present study was conducted to examine the effects of L-carnitine on pulmonary hypertensive response in broiler chickens reared at high altitude and exposed to hypobaric hypoxia. A total of 192 day-old male broilers (Cobb 500) were randomly assigned to 4 treatments and 4 replicates of 12 chicks. A basal diet composed of mainly corn and soybean meal was formulated and served as a control. Th...
