Abstract<br />
A trial was conducted to assess the effects of Panbonis (a herbal vitamin D 3<br />
source) on<br />
performance, some carcass characteristics and tibia parameters of broiler chickens. Mixed-sex<br />
11200 day old Ross × 308 broilers were distributed into 7 dietary treatments with 8 replicates.<br />
Pelleted feeds based on corn, soybean and wheat were given adlibitum. Herbal Vit D 3<br />
were<br />
supplemented 0.01 and 0.02% with the presence of phytase into diets including decreased level<br />
of Vit D 3<br />
from commercial 5000 to 3000 IU. So dietary treatments were consisted of 7 groups<br />
as T1 (5000 IU Vit D 3<br />
at standart Ca and P level) ;T2 (5000 IU Vit D 3<br />
plus Phytase at standart<br />
Ca and P level); T3 (3000 IU Vit D 3<br />
plus 0.01% herbal Vit D 3<br />
plus Phytase at standart Ca<br />
and P level), T4 (3000 IU Vit D 3<br />
plus 0.02% herbal Vit D 3<br />
plus Phytase at standart Ca and P<br />
level), T5 (5000 IU Vit D 3<br />
plus Phytase at low Ca and P level), T6 (3000 IU Vit D 3<br />
plus 0.01%<br />
herbal Vit D 3<br />
plus Phytase at low Ca and P level), T7 (3000 IU Vit D 3<br />
plus 0.02% herbal<br />
Vit D 3<br />
plus Phytase at low Ca and P level). Low Ca and available P level was adjusted to<br />
0.82;0.41, 0.78;0.385 and 0.72;0.36 for starter, grower and finisher respectively while standart<br />
level adjusted to meet araund regular Ross 308 recomendation.<br />
At 24th days of age 2 chicks from each replicates near to average weight of the pen were selected<br />
and killed for bone measurements. All birds were weighed and 2 of those slaughtered for<br />
evaluation of performance and carcass parameters at 41 th day of the study. When overall results<br />
considered, there were no significant difference among treatments in terms of final live weight,<br />
mortality and European Production Efficiency Factor,EPEF (P> 0.05). While birds consumed<br />
diets that contain only phytase and phytase plus herbal Vit D 3<br />
exhibited better FCR than control<br />
group without phytase(P< 0.05), no additional improvement was obtained with herbal Vit D 3<br />
supplementation compared to only phytase. Higher level of herbal Vit D 3<br />
, 0.2%, significantly<br />
decreased feed intake in low Ca and P diets compared to standart Ca, P diets.<br />
Although lowering diet Ca and P level resulted significant reduction(P 0.05). Although tibia weight were not<br />
affceted significantly, low level of Ca and P resulted significant decrease in ash and P content<br />
even supplemented with phytase and/or herbal Vit D 3<br />
compared to standart recomended Ca<br />
and P level for broilers. Higher dose (0.02) of herbal Vit D 3<br />
supplementation seems to have<br />
some adverse effect on final live weight, feed intake and tibia ash. These results indicates that<br />
herbal form of Vit D 3<br />
at 0.01% could replace synthetic vitamin D 3<br />
without any adverse effect on<br />
