ABSTRACT The objective of this research was to investigate the effects a natural herb extract1 (HE) on general growth performance and incidence muscle abnormalities (white striping wooden) broiler chicks. A total 504 one-day old chicks (Ross 500) were used in experiment randomly partitioned into 3 treatments with 7 replicates each (24 per replicate). Three experimental diets (C: regular feed; T...

AIM The objective of this study was to evaluate the effect of organic acids as replacer to antibiotics in their various combinations on feed consumption, body weight gain, and feed conversion ratio (FCR) in broiler chicks during different phases of growth. MATERIALS AND METHODS Antibiotics and organic acids were incorporated into boiler feed in different combinations to form 10 maize based te...

a 70-days experiment was conducted to investigate the effects of natural zeolite (clinoptelolite) on the performance of commercial laying hens. 288 hy-line w36 strain laying hens (50 weeks old) were allotted to 6 dietary treatments including basal diet as control and basal diet supplemented with 1, 2, 3, 4 and 5% zeolite that were fed ad -libitum throughout the experiment. experimental diets fo...

background: previous research has shown that cr is needed for growth and protein synthesis. objectives:  this study was carried out to determine the effects of supplementing chromium-methionine (cr-met) on performance, hematologic characteristics and meat quality parameters in kids. methods: thirty-two male kids (average initial bw of 22 ± 2 kg, 4mo) were used in a completely randomized design ...

A feedlot experiment was conducted under commercial conditions in the Texas Panhandle using 3,757 feedlot steers (average of 94 steers/pen) to evaluate the effects of feeding zilpaterol hydrochloride with or without monensin and tylosin on feedlot performance and carcass characteristics. The experiment was conducted using a randomized complete block design. Treatments were arranged as a 2 (no z...

this study was carried out to evaluate the impacts of organic (sel-plex® selenium yeast) and inorganic (sodium selenite) selenium and vitamin e (d1-α-tocopheryl acetate) on performance and carcass characteristics in broiler chickens. the effect of two types of house temperature and six treatments of feed additives were investigated in a 2×6 factorial experiment at 56 days period with 960 commer...

This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...

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...

A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...
