this study was conducted to evaluate the effect of adding a commercial medicinal plant (mp) powder containing garlic (allium sativum) and thyme (thymus vulgaris) to diets that included olive pulp (op), on the performance and carcass characteristics of broiler chicks. a total of 240 day old male ross-308 broiler chicks were allocated into six iso-nitrogenous and iso-energetic dietary groups with...

The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad der...

This experiment was conducted to evaluate the effect of different levels alfalfa saponins on cholesterol metabolism in broilers. A total of 320 Arbor Acres (AA) broilers of 1 day-old were randomly allotted to 4 treatments with five replicates in each treatment, and with 16 broilers in each replicate. The experiment last 49 days. During the stage from 0 to 3 weeks, broilers in the control group ...

Nine thousand eight hundred, day old male Cobb X Cobb broilers were utilized in a 5x2 factorial design (10 replications/treatment) to determine the effects of five B-vitamins (riboflavin, pantothenic acid, niacin, B12 and folic acid) fortification levels (NRC, 2X, 4X, 8X and 16X NRC) and two levels of stress (low and moderate) on the performance of 0-49 day broilers. Diets were formulated to be...

Three experiments were carried out to evaluate the growth performance and breast yield of broiler chickens fed diets with increasing levels of DDGS and the additions of different enzymes to compensate the energy reduction in DDGS-added diets. In all the experiments Ross B308 male broilers were individually fed. In Exp. 1, 96 broilers from 21 to 35 d of age were used and assigned to 8 treatments...

Cobb male broilers (28 d of age) previously fed same starter diet were offered a single diet (control) and isoproteic choices between 2.950 and 3.250 kcal/g diets from 29 to 50 d. The control and dietary energy choices were fed to broilers housed in one of 2 ambient temperatures: 21 ± 1°C (normal temperature) and 30 ± 0.6°C (heat stress). Broilers housed at 21°C fed isoproteic choices varying i...

A balance trial experiment was carried out to evaluate the potential relationship between an enzymatically hydrolyzed yeast (EHY) and yeast culture combined with a live Bacillus subtilis (Bs) on the productive parameters, ileal digestibility, retention of nutrient and energy and villus morphology in broilers. Seventy two 28 d old, Ross B308 male broilers were assigned to a factorial combination...

Previous experiments have shown lower abdominal and body fat deposition in broilers fed polyunsaturated fatty acids (PUFA) compared with those fed saturated fatty acids (SFA) or monounsaturated fatty acids (MUFA). These changes in fat deposition may be related to different rates of lipid synthesis or lipid oxidation. In Experiment 1, in vivo lipogenesis of broilers fed different dietary fatty a...

An Iowa grain processor attempted to alter the typical 12-h preharvest fasting period by giving broilers cornstarch derivative pellets and water for 6 h followed by 6 h of no feed or water. After slaughter, plant food inspectors determined that livers from the treatment group were lighter in color than normal, and consequently a significant number of chicken carcasses were condemned for human c...

The benefits of feeding avilamycin (Surmax/Maxus, Elanco Animal Health) to broiler chickens were demonstrated in a floor pen study (two trials) in which avilamycin was fed at 10 ppm in a 45-day growout. Final live weight of broilers fed avilamycin was significantly (P < or = .01) heavier (90 g) than that of control broilers fed for an equal number of days. Feed conversion was numerically but no...
