Effects of feeding system, dietary copper supplementation and climatic conditions on performance of adult female and male rabbits [electronic resource].

Includes references.

One hundred and twenty New Zealand White (NZW) adult female and thirty sit adult male rabbits at 6 months of age were used to study the effects of heat stress, feeding time, dietary supplementation with copper (at levels of 0.0, 75 and 150 mg / kg diet) and their interaction, under Egyptian conditions. The results showed that the estimated Temperature – humidity index (TH!) values were 18. 9 at winter (mild period) and 27.4 at summer (hot period), indicating absence of heat stress during winter (less than 22.2) and exposure to severe heat stress during the hot period (23.3-25.5).
