Milk yield in the dairy cattle depend on quality management of feed and fodder. To get better milk production, proper utilizations of nutrients is highly essential for the dairy animals. Usually farmers feed their animals with natural resources like roughage, rice bran, wheat bran etc. without considering balance quantity of feed. During summer season the availability of Green Grass is very less which is essential for the milking animals. The study is carried out to find out the effect of Hydroponic Maize Fodder (HMF) as a substitute of Green fodder during summer
season. 20 lactating cows were selected for this Study (10 cows from Indigenous breed and 10 cows from Cross Breed). Both Breeds of cows again divided into two groups, five cows in each group from. The treated cows of each group were fed concentrate feed along with 10 kg Hydroponic Maize Green Fodder where as the control group cows fed
with concentrated feed without HMF. The feeding trail was tested for 3 months.After the trial period milk yield were recorded for 7 consecutive days & found that the milk yield was significantly higher in the animal fed with HMF in both treated groups as compare to control groups. The use of HMF during summer season can enhance and maintain
dairy farming productivity and improve farmer’s income. Hydroponic Maize Fodder can be a substitute for green grass during summer season on milk yield in indigenous breed and cross breed cows of Ganjam district.
