TL;DR: In the present study, both plant extracts improved the digestibility of the feeds for broilers and the effect of different additives on digestibility improved the performance slightly, but this effect was not statistically significant.

TL;DR: When microbial phytase was added to low-P diets for broilers the availability of P increased to over 60% and the amount of P in the droppings decreased by 50%, and the growth rate and feed conversion ratio were comparable to or even better than those obtained on control diets.
Abstract: Techniques have been developed to produce microbial phytase for addition to diets for simple-stomached animals, with the aim to improve phosphorus availability from phytate-P in plant sources. The activity of the crude microbial phytase showed pH optima at pH 5.5 and 2.5. The enzyme was able to degrade phytate in vitro in soya-bean meal, maize and a liquid compound feed for pigs. When microbial phytase was added to low-P diets for broilers the availability of P increased to over 60% and the amount of P in the droppings decreased by 50%. The growth rate and feed conversion ratio on the low-P diets containing microbial phytase were comparable to or even better than those obtained on control diets. Addition of microbial phytase to diets for growing pigs increased the apparent absorbability of P by 24%. The amount of P in the faeces was 35% lower.

TL;DR: Body weight, feed consumption, and mortality were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) strain and in the 2001 Ross 308 strain of broilers when fed representative 1957 and 2001 diets.

TL;DR: The dietary supplementations resulted in an increase in the villus height and crypt depth of intestinal mucosa of broilers and associated with improvement of growth performance for both synbiotic and probiotic.
