The study was undertaken to assess the nutrient changes occurring during the growth of hydroponic fodder maize (HFM) and effect of feeding HFM on blood biochemical and haematological parameters in cross bred calves. Representative samples of HFM were taken on each day of germination and were oven dried and subjected to chemical analysis. Results showed that crude protein (CP), total ash (TA), ether extract (EE), crude fiber(CF) and acid insoluble ash increased whereas nitrogen free extract(NFE) decreased (p<0.05) in the HFM when compared with the original grain. For animal experimentation fifteen healthy crossbred calves of three months age were selected and divided into three groups of five each based on age, sex and body weight and allotted randomly to three experimental treatments T1 (control), T2 (50% of calf starter replaced by HFM on dry matter basis), T3 (75% of calf starter replaced by HFM on dry matter basis). All the experimental animals were fed with calf starter containing 24% CP and 70%TDN and were fed as per ICAR standard (2013). Feeding trial was conducted for a period of 90 days. The haemato- biochemical parameters such as plasma protein, plasma glucose, serum calcium, serum phosphorus, blood urea nitrogen, serum cholesterol and triglycerides did not show any significant difference (P >0.05) among the groups. It can be concluded that HFM is more nutritious than conventional fodder maize and calf starter can be replaced with HFM on dry matter basis at 75 percent level without any adverse effect on the haemato-biochemical parameters in cross bred calves.
