Efficiency of Peppermint (Mentha piperita) Powder on Performance, Body Temperature and Carcass Characteristics of Broiler Chickens in Heat Stress Condition
This experiment was carried out to evaluate different levels of peppermint (Mentha piperita) plant powder usage on feed conversion ratio (FCR), body weight (BW), feed intake (FI), body temperature, carcass parts (breast and thigh) and internal organs (liver, heart, gizzard) weights in broiler chicken. A total of 192 broiler chicken were randomly divided into 4 experimental treatments with 4 rep...
متن کاملBrain and Hepatic Hsp70 Protein Levels in Heat- Acclimated Broiler Chickens During Heat Stress
In the present study we have investigated the effects of heat acclimation on brain and hepatic Hsp70 protein levels and body temperature of broiler chickens in response to gradual heat stress. Two groups of broilers were raised up to 47 days of age under distinct temperature conditions: thermoneutral (TN, according to bird age) or hot environmental (HS, 31-33°C). At 46 days of age, the birds re...
متن کاملInvestigation of the Effect of Silver Nanoparticles Coated on Zeolite on Performance, Intestinal Morphology and Gastrointestinal Microbial Population in Broiler Chickens under Heat Stress Conditions
Nowadays silver nanoparticles are being considered as an alternative to antibiotics. Silver is one of the most important elements in nanotechnology due to extensive antibacterial activity. The aim of present experiment was to evaluate the effect of silver nanoparticles coated on zeolite and organic acids on performance, intestinal morphology, gastrointestinal microbial population and carcass ch...
متن کاملEffects of Using a Multi-Strain Probiotic on Performance, Immune Responses and Cecal Microflora Composition in Broiler Chickens Reared Under Cyclic Heat Stress Condition
This experiment was conducted to examine the effect of multi-strain probiotic (Primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. A total of 96 one-d-old mixed sex broiler chicks (Ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. The dietary treatments were basal di...
متن کاملEffect of Peppermint (Mentha piperita) Powder on Immune Response of Broiler Chickens in Heat Stress
To study the effect of different levels of peppermint (Mentha piperita) plant powder, on immune system of broilers under heat stress condition, 192 one-day old chickens (Ross, 308) were randomly allocated to 4 dietary treatments with 4 replicates of 12 chicks each, using a completely randomized design. The four groups were characterized by a basal diet (control), basal diet supplemented with 1 ...
