Corn distillers dried grains with solubles (DDGS) are now being further processed to remove corn oil, which may be used as a dietary energy source for poultry. The objectives of this study were to compare the effects of a poultry fat (PF) and a new DDGS-derived corn oil blend (CO) on live performance and carcass characteristics of 49-d-old broilers. Four corn-soybean meal based diets were formu...
Considerable savings can be realized and performance can be improved by formulating poultry feeds based on the daily feed intake and nutrient needs of the chicken. Programmes have been developed for commercial layers, broiler breeders, and replacement pullets for commercial egg production. Programmes have also been suggested for broiler breeder replacements for this purpose. Suggestions have be...
The objective of this experiment was to evaluate the effect of feeding different levels of garlic and cinnamon powder on antioxidant system and some blood parameters of broilers under heat stress condition. Two hundred forty commercial broiler chicks (ROSS 308) were dividing to 6 treatments and 4 replicates. This experiment was performed in a completely randomized design with 2*3 factorial tria...
The present study was conducted to determine the effects of two types of housing systems and early age feed restriction on stress and fear reactions, and performance in broiler chickens raised in a hot, humid tropical climate. On day 1, chicks were housed either in windowless environmentally controlled chambers (temperature was set at 32°C on day 1 and gradually reduced to 23°C by day 21) or in...

This study was conducted to evaluate the effects of dietary nettle (Urtica dioica) medicinal plant supplementation on growth performance, carcass traits, and blood biochemical and immunity parameters in female broiler chicks. A total of 300 (Ross-308) broilers were randomly allocated into one of the following dietary treatments: 1) control, " # " $ % # " $ % # " $ % # " $ % $ & ' $ chicks per p...
This study was conducted to examine the effects of physical form of diet on humoral and cellular immune responses in broiler chickens exposed to carbon tetrachloride stress in days 10 to 42 of age. The 2×3 factorial experiment performed in a randomized complete block design with 468 broilers in 6 treatments and 6 replicates of 13 birds each. The treatments consisted combinations of a grower d...
