Abstract
Heat stress is one of the most crucial issues in broiler production, particularly in tropical regions. Ginger can serve as an antioxidant. Being part of the nutritional interventions, treatment using ginger has been documented to alleviate the negative impact of heat stress on broiler chickens, in terms of production, physiology, immunology, and antioxidant status of broilers. The present review elucidates the alleviation of heat stress in broiler chicken using ginger based on the most recent literature in order to provide complete information on the impact of ginger powder (GP) on haematology, biochemistry and thyroid hormones of broilers under heat stress (HS) (34 ± 2° C) and thermoneutral temperature (TN) (22 ± 4 °C). An 80 of one-day-old broiler chicks (cobb-500), 20 birds in each group either control (basal diet) or 0.75% ginger. Chronic HS at 42 d of age resulted in significant decrease in PCV, RBCs, total protein, Albumin, serum T3 and T4, whereas increased H/L, triglycerides, cholesterol, LDL-cholesterol, uric acid, AST, ALP, ALT, DBIL, TBIL, and creatinine significantly. Supplementation of GP significantly increased PCV, RBCs, total protein, albumin while significant decrease in AST, uric acid and improvements in lipid profile parameters. Findings of the research study indicated that ginger has improved birds health.
Highlights
Poultry industry can provide very high-quality proteins for human nutrition and it is a source of national income for the community in many countries
Chronic heatstressed broilers had a significant decrease (P
The current study showed that the H and H/L values of broilers under heat stress were substantially higher with a substantial decrease in monocytes than in the TNC population due to elevation of plasma corticosterone that in accordance with [19]
Summary
Poultry industry can provide very high-quality proteins for human nutrition and it is a source of national income for the community in many countries. Broiler farming seems to be a part of meat production and consumption in the country so numerous researches worked on broilers developments resulted in breeding programs enhanced feed utilization and growth rate. The frequency of high-temperature days is expected to increase with climate change worldwide, and heat stress (HS) has become one of the most common environmental factors that challenge broiler production [2]. The retarded growth rate, increased disease outbreaks, and mortality is amongst the problems related to heat stress in broiler production. Preliminary research indicates nine compounds that bind to serotonin receptors which influenced the gastrointestinal function.
