The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...

The article presents the results of a comprehensive assessment possibility producing large meat chickens domestic and foreign crosses with cage method growing, considering separation by gender. highest broiler productivity index was 213 units, which is 27 units higher than when growing broilers cross. content histidine significantly in cross (by 0.50 g muscles cockerels 0.54 hens).

A diarrheagenic toxin from culture extracts of Aspergillus wentii Wehmer isolated from weevil-damaged Chinese chestnuts was identified as emodin (2-methyl-4,5,7-trihydroxyanthraquinone). The orange-red, crystalline toxin (mp 255 to 257 C) showed ultraviolet absorption maxima in ethyl alcohol at 223, 250, 267, 290, and 442 nm, and infrared absorption maxima at 3,400 cm-1 (OH), 1,635, and 1,625 C...

A study was undertaken to investigate the effect of Salmonella gallinarum endotoxin on clinical symptoms and some haematological changes in mature six-month-old cockerels. Salmonella gallinarum endotoxin caused characteristic clinical symptoms, severe olygocytic hypochromic anaemia, leucocytosis and increased phagocytic function of leucocytes. Heterophilia was associated with relative lyphopeni...

the present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. the pomegranate peel and pulp samples were gathered from three industries. this study had two experiments. each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). the cockerels fed conventional addition method (cam). the ...
