Abstract
Local feeds have the potential to be used as feed ingredients in poultry diets. This study was to evaluate
the effects of local diets supplemented with ginger and turmeric meal and to compare with commercial broiler
feeds. In total, 180 one-day-old broilers were assigned to 36 pens and kept for 5-7 weeks. The birds were fed
experimental diets as follows control group (R1), the birds were fed as commercial diets, experimental diets
were: local feed + 2% ginger (R2), local feed + 2% turmeric (R3), local feed + 1% ginger + 1% turmeric (R4) and
slaughter age treatments: 5 weeks (P1), 6 weeks (P2), 7 weeks (P3) with 3 replicates. The results revealed no
significant interaction between diet type and slaughter age. The inclusion of ginger and turmeric meal in local
diets resulted in a significant (P<0.05) enhancement of immunity, evidenced by increased sizes of immune
organs, ventriculus, small intestine, and caecum compared to commercial diets. However, these dietary
treatments significantly reduced rectal temperature and respiration rate. Differences in the slaughter age of
chicken (5, 6, and 7 weeks) were significantly increased rectal temperature and respiration rate but significantly
decreased immune organ sizes and visceral organs weights. This study concludes that the inclusion of 1% ginger
and 1% turmeric meal in local diets (R4) offers a more efficient formulation, as it utilizes lower levels of additives
while still yielding favourable outcomes. This dietary strategy enhanced immune organ development and
visceral organ weights in broiler chickens, despite the general trend of increasing age being associated with
elevated rectal temperature and respiration rate. Furthermore, based on physiological, immunological, and
visceral organ parameters, the optimal slaughter age for broiler chickens fed local diets supplemented with
ginger and turmeric meal (R2, R3, and R4) was determined to be 5 weeks (P1)
