effect of nutrition management on fattening performance and on cost benefit analysis in lori-bakhiari lambs

forty-two weaned lori-bakhtiari lambs were taken in an investigation for the effects of two-nutritional management methods of restricted vs. re-alimentation feeding on intake, growth and as well on the cost benefit analysis. during the feed restriction period (frp), the control (c) animals were fed low-quality roughage ad libitum, plus mixed concentrate. the restricted animals (r) were fed only low-quality roughage. in the re-alimentation periods (raps), the lambs due for restricted treatment were divided into two groups of r1 and r2. they received low-quality roughage along with two different levels of concentrate supplement as mentioned before. during restriction period, the c group had a significantly higher (p
