the 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicatesand 10 eggs per each replicate. treatments including: (t1; control; without injection), (t2; injected with 0.3ml saline 9.0%; sham control), (t3, t4 and t5) 25, 75, 125 ppm fe-nano, (t6, t7 and t8) 50, 100, 150 ppmfe-nano-alimet chelate, (t9, t10 and t11) 50, 100, 150 ppm fe-aliment chela...

Broth is a product made from beef or poultry by cooking ingredients rich in protein and water, with without the addition of spices, vegetable fat sodium chloride. This study aims to determine physicochemical properties including crude protein, ash, fat, carbohydrates, water activity, pH as well organoleptic tests three types broth different chicken meat, namely broiler, free-range chicken, IPB-...

The pharmacokinetics and bioavailability of enrofloxacin was compared in Cobb strain broiler chicken after intravenous and oral administration of enrofloxacin at the rate of 10mg.kg -1 . The concentration of enrofloxacin at various time intervals in plasma was determined by HPLC and the pharmacokinetic parameters were calculated by non compartmental approach. AUC was significantly high in i.v. ...

Two unique chicken F(2) populations generated from a broiler breeder male line and 2 genetically distinct inbred (>99%) chicken lines (Leghorn and Fayoumi) were used for whole genome QTL analysis. Twelve phenotypic skeletal integrity traits (6 absolute and 6 relative traits) were measured or calculated, including bone mineral content, bone mineral density, tibia length, shank length, shank weig...

In chickens, the sensory organs for taste are the taste buds in the oral cavity, of which there are ~240-360 in total number as estimated by scanning electron microscopy (SEM). There is not an easy way to visualize all taste buds in chickens. Here, we report a highly efficient method for labeling chicken taste buds in oral epithelial sheets using the molecular markers Vimentin and α-Gustducin. ...

The CO2 production rates from various animal species were measured as well as the ventilation rates (VR) in environmental rooms at Michigan State University over the course of 15 studies that considered dietary strategies to alter air emissions, including two dairy cow studies, four steer studies, two swine studies, one turkey study, four laying hen studies, and two broiler chicken studies. The...

A series of incubation and broiler growth studies were conducted using one strain of broiler chicken (fast feathering dam line) observing incubation effects on femoral bone ash % at hatch and the ability of the bird to remain standing at 6 weeks of age (Latency-To-Lie). Egg shell temperatures during incubation were consistently recorded. Parsimonious models were developed across eight studies u...

Environmental conditions during incubation such as temperature and O(2) concentration affect embryo development that may be associated with modifications in nutrient partitioning. Additionally, prenatal conditions can affect postnatal nutrient utilization. Using broiler chicken embryos, we studied the effects of eggshell temperature (EST; 37.8 or 38.9 degrees C) and O(2) (17, 21, or 25%) applie...

Broiler chicks are transported to production sites within one to 2 d post-hatch. Possible effects of this transportation are poorly understood and could vary among chicks from breeder flocks of different ages. The aim of the present study was to investigate the effects of transportation duration and parental flock age on chick welfare, productivity, and quality. After hatch in a commercial hatc...

The bacterial succession on the skin of broiler chicken carcasses stored at 2 degrees C was traced, and the ability of representative isolates to produce off-odors was determined by using sterile leg and breast muscle sections. Off-odors were identified by olfactory and chemical means. The inability of peptone-iron agar to detect sulfide-producing strains was noted.
