Aim: To determine the effect of severity of 
                              Haemonchus contortus infection on performance and 
                              economics of raising kids fed on two respective 
                              plane of nutrition. 
                              
                              Materials and Methods: 
                              The feeding trial was conducted for 120 days with 
                              non-descript female kids (3-5 months age). The 
                              kids were randomly allocated into two dietary 
                              treatments having normal protein normal energy (NPNE) 
                              and high protein medium energy (HPME) using 
                              conventional feedstuffs (crushed maize, ground nut 
                              cake, berseem hay and chaffed paddy straw), 
                              fortified with mineral mixture (1%), salt (0.5%) 
                              and vitamin premix (@ 20gq-1 feed), each treatment 
                              having three levels of H. contortus infection (W0, 
                              W500 and W2000) in a 2x3 factorial design. The 
                              study was undertaken to ascertain the performance 
                              and economics of raising kids fed on higher plane 
                              of nutrition. 
                              
                              Results: The total dry matter 
                              intake (DMI: kg) was 41.18, 39.56 and 41.11 in W0, 
                              W500 and W2000 in group HPME; whereas in NPNE the 
                              DMI was 39.66, 38.03 and 35.95 kg in the 
                              respective infection levels. The highest body 
                              weight gain was obtained in HPME than NPNE from 
                              1st to 16th week of experiment. The infected kids 
                              at NPNE gained at a slower rate as compared to the 
                              kids maintained at HPME. The mean percentage of 
                              monocytes, lymphocytes and neutrophils fluctuated 
                              in different ways throughout the experiment 
                              without any significant difference and these cells 
                              were not followed any specific trend. However, 
                              significantly higher (P<0.05) eosinophils count 
                              was recorded in W500 and W2000 of HPME fed kids as 
                              compared to W500 and W2000 of NPNE fed kids. In 
                              the present study the maximum benefit could be 
                              obtained by feeding of HPME diet with W500 
                              infection as compared to other treatments. 
                              
                              
                              Conclusion: The cost of raising kids per kg 
                              meat was worked out to be the most economical at 
                              high plane of nutrition even with the heavy H. 
                              contortus infection.
