Effect of Ochratoxin A on Body Weight, Feed Intake and Feed Conversion in Broiler Chicken
The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...
متن کاملVariation in feed intake of broiler chickens
With many broiler diets, particularly wheat–based diets, rate of passage of digesta limits intake and growth. In many trials, the relationship between feed intake and apparent metabolizable energy (AME) was negative or insignificant. In some trials, the limitation to voluntary intake was so severe that negative relationships existed between it and FCR. This is a consequence of the diversion of ...
متن کاملFeed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملGrowth Performance, Carcass Characteristics and Intestinal Microflora of Broiler Chickens Fed Diets Containing Carum copticum Essential Oil
We evaluated the effects of dietary Carum copticum essential oil (CCEO) on growth performance, carcass characteristics and intestinal microflora of broiler chickens. A total of 240 Cobb broiler chickens were allocated to five dietary treatments, each with four replicates of 12 birds. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free of antibiotics (Control) and...
متن کاملEstimating and Predicting Feed Conversion in Broiler Chickens by Modeling Covariance Structure
Modeling covariance structure was used to estimate and to predict feed conversion in broiler chickens from one experiment under repeated-measures design. Eight treatments that consisted in a combination of four strains (Arbor Acres, Ag Ross 308, Cobb and RX) and two sexes were evaluated at six ages (7, 14, 21, 28, 35 and 42 d) in two blocks with three replicates per block. Feed conversion was s...
