Heat ameliorative measures on haematology in broiler rabbits.

摘要

The study was conducted at the Livestock Farm, Department of Livestock Production and Management, Veterinary College and Research Institute, Namakkal, Tamil Nadu, India on 24 rabbits (White Giant and Soviet Chinchilla) to determine the influence of heat control measures on haematology during heat stress. The animals were divided into four groups: T1 (control) was provided with cool drinking water; T2 was provided with colder water and electrolytes; T3 was given electrolytes (1 g/kg/litre of water) and sprayed with water; and T4 was given plain water and sprayed with water for 5-10 min twice daily. Blood was collected for haematological analysis. Results revealed that the haemoglobin and PCV values of the control rabbits were higher than the treatment groups. The total erythrocyte count (TEC) and total leukocyte count (TLC) in T3 and T4 White Giant rabbits increased, respectively. The TEC and TLC decreased in both rabbit breeds in T1. It is concluded that the heat controlled measures are partly successful in managing heat stress due to the improved TLC and TEC..
