Effect of Replacing of Dried Bread in Stead of Barely in Fattening Rations on Some Productive، Hematological and Economic Benefits Characteristics in Local Rabbits.

Abstract

This study was conducted in order to detect the effects of replacement of different ratios of dried bread in stead of local black barely in local rabbit rations and its effects on some physiological , productive characteristics and economic benefits . Twenty four local rabbits (30-45) days aged were distributed in to 4 groups ( 6 rabbits / group) and they were treated as follows . The 1st group ( control ) were given standard rations while the 2nd , 3rd and 4th groups were given rations in which dried bread were replaced instead of barely in the rations of 12,24,36% respectively treatments were continued for 8 weeks . The results revealed that the baker replacement caused significant reduction in most productive characters . There were no significant effects on hematological characteristics . And about the economic benefits : the baker replacement caused a reduction of net return and investment and the reduction increased with the increase of replacement ratio . Generally the study showed that it is possible to replace the barely by dried bread (12%) in the rations
