We determined the effect of caponization on the carcass and giblet characteristics, and skin and muscle color in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks old and were fed growing and finishing diets ad libitum during an eighteen-week experimental period. The results showed that the percentage of dressing, heart, feet, thigh, head and neck were signif...

Abstract The use of modern chicken genotypes with high egg or meat performance results in the ethically unacceptable practice culling day-old male layer chicks because their inefficient fattening performance. Dual-purpose a balanced profile for both eggs and are one option to avoid this practice. In study, four crosses breed (White Rock New Hampshire) Bresse Gauloise were compared under conditi...

This study was designed to evaluate pharmacokinetics of sulphadimidine   in cockerels fed on subclinical dose of arsenic (100 ppm) in diet and to determine the protective efficacy following simultaneous dietary medication with Piper longum (pipli)   (100 ppm) in a 12-week feeding trial. Pharmacokinetic parameters were determined after single i.v. dose (50 mg/kg) of sulphadimidine ...

Estrogens are highly effective both prophylactieally and therapeutically against cholesterol-induced coronary atherogenesis in cockerels. The relative immunity of premenopausal women to coronary sclerosis may be related to the presence of these ovarian hormones. Therefore, estrogens may be useful in the treatment of human coronary atherosclerosis. With this object in mind, the elimination of th...

BACKGROUND Environmental tobacco smoke has been blamed for approximately 40,000 excess deaths from heart disease annually in the United States. As yet, no pathophysiological process that could be responsible for these deaths has been identified. Environmental tobacco smoke is composed mainly of aged and diluted sidestream smoke but also contains 15% to 20% exhaled mainstream smoke. Carcinogens,...

The plasma glucose-insulin relationships and thyroid status were investigated in two lines of adult cockerels divergently selected for high (R+) or low (R-) residual food consumption (RFC). For a given body weight, R+ birds had a 74% higher food intake than R- birds. Plasma glucose concentrations were significantly lower in the R+ line compared with the R- when fasted, whereas R+ birds exhibite...

Aim of study: To evaluate the effect different diets on carcass characteristics and meat quality from Mos free-ranged cockerel.Area Galicia (NW Spain).Material methods: Cockerels (n=75) were allocated to 3 groups (n=25) according finishing diets: commercial fodder (CF), 50% wheat corn (WH) 33% 66% (CR). Meat was assessed in terms physicochemical, nutritional features.Main results: The highest l...

Forty (40), thirteen weeks old cockerels were allocated to five dietary treatments after balancing for weight. The eight birds on each treatment replicated four times, such that two served as a replicate. In diet 1 (control) contain 0% Palm Kernel Cake (KPC) and Deoiled (DOC). Diet 2 3 continued 40% KPC, was presented in mash form while pellet. Diets 4 5 contained DOC, % Dietary had no effect (...

In nonlaying hens or in cockerels, the administration of estrogen dramatically increases the level of plasma triglycerides (1, 2). Luskey et al. (3) have shown that one effect of estrogen was to increase the rate of synthesis of the very low density lipoproteins (VLDIJ’ proteins. The mechanism for this induction is presumably through an increase in mRNA for the yolk proteins (4-6). In a recent ...

The present study demonstrates that estrogens reverse previously induced coronary atherosclerosis in cholesterol-fed cockerels, despite the continued presence of the atherogenic stimulus in the diet. Aorta atherogenesis remains unaffected. Hypercholesterolemia is moderately enhanced by estrogen administration; total cholesterol-lipid phosphorus (C/P) ratios are depressed to normal levels, conse...
