This study was to evaluate</p> <p class="p1">the effects of local diets supplemented with ginger and turmeric meal and to compare with commercial broiler</p> <p class="p1">feeds. In total, 180 one-day-old broilers were assigned to 36 pens and kept for 5-7 weeks. The birds were fed</p> <p class="p1">experimental diets as follows control group (R1), the birds were fed as commercial diets, experimental diets</p> <p class="p1">were: local feed + 2% ginger (R2), local feed + 2% turmeric (R3), local feed + 1% ginger + 1% turmeric (R4) and</p> <p class="p1">slaughter age treatments: 5 weeks (P1), 6 weeks (P2), 7 weeks (P3) with 3 replicates. The results revealed no</p> <p class="p1">significant interaction between diet type and slaughter age. The inclusion of ginger and turmeric meal in local</p> <p class="p1">diets resulted in a significant (P&lt;0.05) enhancement of immunity, evidenced by increased sizes of immune</p> <p class="p1">organs, ventriculus, small intestine, and caecum compared to commercial diets. However, these dietary</p> <p class="p1">treatments significantly reduced rectal temperature and respiration rate. Differences in the slaughter age of</p> <p class="p1">chicken (5, 6, and 7 weeks) were significantly increased rectal temperature and respiration rate but significantly</p> <p class="p1">decreased immune organ sizes and visceral organs weights. This study concludes that the inclusion of 1% ginger</p> <p class="p1">and 1% turmeric meal in local diets (R4) offers a more efficient formulation, as it utilizes lower levels of additives</p> <p class="p1">while still yielding favourable outcomes. This dietary strategy enhanced immune organ development and</p> <p class="p1">visceral organ weights in broiler chickens, despite the general trend of increasing age being associated with</p> <p class="p1">elevated rectal temperature and respiration rate. Furthermore, based on physiological, immunological, and</p> <p class="p1">visceral organ parameters, the optimal slaughter age for broiler chickens fed local diets supplemented with</p> <p class="p1">ginger and turmeric meal (R2, R3, and R4) was determined to be 5 weeks (P1)</p> 2026-04-08T16:17:35+07:00 Copyright (c) 2026 ANIMAL PRODUCTION
