| ABSTRACT Objectives of the present study were to assess the hatchery based interventions and their impact on hatching traits and subsequent performance of broilers. In total, 3000 eggs of Hubbard broiler breeders were equally divided into Small (50-55 g), Medium (56-61 g) and Large (62-70 g) eggs. The eggs from each category were distributed into 20 trays each containing 50 eggs. Each tray was considered as a replicate. At the end of the 18th day of incubation, the eggs of each weight category were divided into four different patio strategies i.e. P0, P3, P5 and P7 where feed and water were provided to the chicks for 0, 3, 5 and 7 days in the hatcher followed by conventional rearing. Data were collected for hatch window, hatching traits, growth, physical... |

| ABSTRACT The objective of the current study was to check the effect of fat types and polyglycerol polyricinoleate (PGPR) levels in broiler diets on broilers performance. For this purpose, three sources of fat {soy oil (SO), poultry oil (PO), and oxidized oil (OO) (oxidized soy oil)} and four levels of PGPR were used in a 3×4 factorial arrangement. The trial had 12 different dietary treatments: (T1) basal ration (BR) containing SO without PGPR supplementation, (T2) BR containing PO without PGPR supplementation, (T3) BR containing OO without PGPR supplementation, (T4) BR containing SO with PGPR supplementation (0.025%), (T5) BR containing PO with PGPR supplementation (0.025%), (T6) BR containing OO with PGPR supplementation (0.025%), (T7) BR containing SO... |

| ABSTRACT The purpose of this study was to evaluate the effect of fat sources and emulsifier supplementation in different phases on growth performance of broilers. Treatments were; (T1) basal ration (BR) which contained soy oil (SO) and had inclusion of emulsifier for whole life, (T2) BR which contained poultry fat (PO) and had inclusion of emulsifier for whole life, (T3) BR which contained oxidized oil (OO) and had inclusion of emulsifier for whole life, (T4) BR which contained SO and had inclusion of emulsifier during starter phase (T5) BR which contained PO and had inclusion of emulsifier during the starter phase, (T6) BR which contained OO and had inclusion of emulsifier during the starter phase, (T7) BR which contained SO and had inclusion of... |

| ABSTRACT The aim of the present study was to investigate the influence of different growth promoters on broiler performance and intestinal morphology reared under various stocking densities. A total of 900 day old (Ross-308) straight run broilers were randomly divided into fifteen treatment groups according to a completely randomized design. A 5 × 3 factorial arrangement of treatment was employed. Treatments were consisted of four growth promoters (antibiotics, prebiotics, probiotics, and symbiotics) and a control group with three stocking densities (0.046, 0.056, 0.065m2). Each treatment was replicated 6 times with 10 birds in each. Regarding growth performance, feed intake (p=0.0008), body weight (p=0.0085) and feed conversion ratio (p=0.0001) were... |

| ABSTRACT The current study was planned to investigate the influence of soy oil, oxidized soy oil, poultry oil single refined and poultry oil double refined on the performance of broilers chicken. A total of two hundred and forty, day-old broiler chicks were divided into 4 treatments in such a way that each treatment had six replicates and each replicate had ten chicks. The experimental treatments were separated with the usage of single refined poultry oil, double refined poultry oil, oxidized soy oil and soy oil in the diet of broilers. In both starter and overall periods average body weight was higher (p<0.05) for birds which were on a basal diet containing soy oil as compared to other diets. Similarly, feed intake was higher (p<0.05) for birds... |
