Kajli is one of the most beautiful breeds of sheep in Punjab-Pakistan. That is why, at the same weight, Kajli lambs fetch higher prices than other sheep breeds. Because of their beauty, they are usually reared for sacrificial purposes rather than for general meat purposes. Well fed Kajli lambs, kept for sacrificial purposes, can achieve as high as 80 kg body weight at the age of one year. However, nothing is known about their feeding as they can be fed anything from whole gram to DAAL or gram flour without keeping any account. There is a dire need to appraise the meat production potential of Kajli lambs to see their cost effectiveness for meat production in the country. This study was planned to examine the influence of various protein sources with or without probiotics on the nutrient intake and their digestibility, growth and fattening performance, blood metabolites and carcass characteristics of Kajli male lambs.
