this study was carried out to examine the effect of post hatch fasting (phf) period with and without subcutaneous injection of 0.6 ml ca-gluconate (ca-g) on productive performance and breast muscle development in broiler chicks up to day 28 of age. weight gain (wg) and feed intake (fi) were significantly reduced and fcr was increased as phf lasted for 36 h. injection of ca-g did not improve wg ...

results the means ± standard deviations of the averaged emg during the lateral and frontal wp exercises were 40.1 ± 19.1, and 23.7 ± 11.3 µv, respectively. those of the percent maximal voluntary contraction during the lateral and frontal wp exercises were 51.4 ± 29.7, and 31.3 ± 20.5, respectively. gmax activity during the lateral wp exercise was significantly higher than that during the fronta...

The production performance and meat quality of the slow-growing hybrid Hubbard JA757 were monitored under conditions diets differentiated by crude protein content. A total 1200 as-hatched day-old chickens equally randomly allotted into two treatments (T-1 T-2), with six replicates provided for each treatment (100 chickens/replicate). T-1 received standard (according to Company recommendations),...

Mongolian × Versicolor and common pheasants were investigated. Birds were kept in a confined, environmentally controlled facility without outdoor access and fed ad libitum commercial diets for slaughter pheasants. Body weight was determined at the end of 6, 10 and 13 weeks of rearing, and body weight and body measurements were determined in 16-week-old pheasants. At 16 weeks, 20 pheasants were ...

We investigated the effects of dietary β-1,4-mannobiose (MNB) on the weights of body, breast muscles, thighs, liver, and abdominal adipose tissue in growing broiler chicks to evaluate whether MNB can be used as a feed additive for broiler chicks. A total of 24 eight day-old male broiler chicks were allocated to two cages and fed a control diet or a 0.01% MNB-supplemented diet for 14 days. Dieta...

The life of game birds (pheasants) in nature is coupled with a number of difficulties in all seasons of the year. This refers to finding food, breeding, laying eggs, raising the young, fleeing from their natural enemies and lack of protection from unfavorable climatic conditions. The pheasants that live in captivity--aviaries for pheasants--do not have such difficulties--they are fed regularly ...

The objective of this study was to evaluate the characteristics carcass, physicochemical properties as well nutritional composition in breast and leg meat (with skin) two different genotypes wild birds namely: pintail (Anas acuta) shoveler (Spatula clypeata) with regard sex effect. involved forty-eight birds, 24 shovelers (1:1 ratio) harvested during hunting season (in September November 2020) ...

The aim of this research is to compare the carcass composition and meat quality characteristics spent Cobb 500 Ross 308 broiler breeders. A total 28 carcasses were evaluated—7 female 7 male from each genotype. Dissection was performed, percentages neck, wings, skin with subcutaneous fat, abdominal residual components, breast leg muscles calculated relative eviscerated weight. evaluated for thei...

the objective of the present study was to determine the effects of feeding high levels of l-arginine on growth performance, blood metabolites, and carcass meat quality of female ross broiler chickens at the starter period. in this experiment, 192 day old chicks were fed with 4 dietary treatments (100%, 153%, 168% and 183% of digestible arginine, based on the ross catalogue recommendation) with ...

An experiment was conducted to determine the effects of caponization on the growth performance, breast and thigh muscles physical properties and fiber diameter of the Pectoralis major and Gastrocnemius pars externa in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks of age. Birds were fed grower and finisher diets ad libitum during an eighteen-week experimen...
