Ileal digestibility of energy and amino acids in three faba bean cultivars (Vicia faba L.) planted and harvested early or late in broiler chickens.

A concern of both pulse growers and poultry producers is how the timing of planting and harvesting affect the nutritional quality of faba bean for broiler chickens. To investigate, half of the seed of 2 zero-tannin cultivars (Snowbird and Snowdrop) and 1 low vicine and convicine cultivar (Fabelle) were planted at a single site either in early May and harvested in late September (EARLY) or planted in late May and harvested in late October (LATE). Diets of the 3 EARLY or LATE cultivars (95% inclusion) were fed to 756 broiler chickens (Ross 708) from d 15.

A microcomputer network for the differential leucocyte count and the registration of red blood cell morphology.

A microcomputer network is described for the scoring of the differential leucocyte count and the registration of white and red cell characteristics. On each terminal keyboard, keys are assigned to white cell fractions (10), erythroblasts (1), red (13) and white (3) cell morphology and for graduations 1+ to 4+. Duplicate counts on different microscopes are collected by the master, averaged and forwarded to a printer.
