EFFECT OF ZINGIBER OFFICINALE ON GROWTH AND BLOOD PROFILE OF BROILER CHICKEN

Abstract

The poultry sector plays a significant role in Pakistan's economic development and protein supply, contributing 1.3% to the economy and 26.8% of meat demand. However, excessive antibiotic use has raised issues for antibiotic-resistant bacteria and concerns over meat quality. Consequently, natural additives like ginger, known for its antimicrobial properties, are increasingly used to reduce antibiotic reliance in poultry. This study aimed to evaluate the effects of various concentrations of Zingiber officinale (ginger powder) at 1, 1.5, and 2% on the growth, carcass characteristics, and blood profile of broiler chickens during summer and winter. A five-day-old broiler chicken was divided into four groups (one control and three experimental) and observed for 42 days per season. Weekly feed intake and weight gain were recorded to determine the feed conversion ratio (FCR). Blood samples collected on day 42 were analyzed for glucose, lipid profile, and antibody titters. Results indicated that 2% ginger supplementation significantly increased body weight gain in winter (p<0.05). Carcass characteristics showed non-significant differences (p>0.05). The 2% ginger diet significantly improved lipid profiles and antibody titers, reducing cholesterol, LDL, triglycerides, and increasing HDL, ND, and IBD titers, especially in winter. Thus, 2% ginger supplementation enhances broiler growth and health, particularly in winter.
