ates on performance parameters, carcass parameters, and liver,
intestinal cells, and intestinal villi lengths were investigated. A total
of 180 1-day-old quails (Coturnix coturnix Japonica) were used as the
animal material of the study. The animals in the study were divided
into 3 groups: control and experimental, and groups were allotted into
cages with 6 replications containing 5 males and 5 females each. In
the experiment, quail chicks were fed with one of 3 experimental diets
from the first day of the experiment: the first group was fed with a
normal phosphorus diet without any additives. The second group was
fed a 150 FTU/kg phytase added diet. The third group was fed a diet
with 300 FTU/kg phytase added to it. The experimental period lasted 6
weeks. The phytase used in the study was produced by the researchers.
At the end of the study, the animals with the highest body weight gain
and feed consumption were in the 300 FTU/kg group, while those with
the lowest body weight gain and feed consumption were in the control
group. However, there was no difference between the groups in terms
of feed conversion ratio and cold carcass, thigh, and wing weights. In
addition, the longest villus length was observed in the diet with the
addition of 300 FTU/kg of phytase. As a result, phytase supplementation
was shown to have a positive effect on both growth performance and
the intestinal health of quails.
