    Abstract: This study was planned to investigate the effect of aditional 
  lyzozyme to milk on growth performances of Holstein calves. About 15 female 
  and 18 male Holstein calves were used in this study. Between day 4 and 60, calves 
  were fed with whole milk from a pail twice a day such that each calf received 
  228 L whole milk (4 L day<SUP>-1</SUP>) over the whole experiment. All calves 
  were fed <I>ad libitum </I>with calf starter along with alfalfa hay. Calves 
  was fed with milk which is additional (10 mg L<SUP>-1</SUP>) lysozyme during 
  milk fed period. During 0-35 days period of the experiment, lysozyme supplementation 
  decreased daily gain and increased feed to gain ratio (p&lt;0.05) and male calve 
  had higher daily gain, feed intake and better feed to gain ratio in the same 
  period (p&lt;0.01). The effects of lysozyme and gender on daily gain and feed 
  to gain ratio have disappeared during 35-60 days period. Lysozyme decreased 
  feed intake (p&lt;0.05) during 35-60 days of experiment. Similarly overall feed 
  intake, daily gain and feed to gain ratio were not affected by lysozyme (p&gt;0.05). 
  Male calve had higher daily gain and weaning weight and lower feed to gain ratio 
  than female calve throughout the study (p&lt;0.05). Lysozyme x gender interaction 
  affected feed intake in all experimental period and male receiving control diet 
  had higher feed intake than female but lysozyme supplemented male calves had 
  lower feed intake than female ones (p&lt;0.05). The results revealed that lysozyme 
  may deteriorate of adaptation of the microflora of the gastrointestinal system 
  of 5 weeks old calves and be tended to decrease diarrhea cases during preweaning 
  period.
