A feeding trial of 90 days was carried out in early lactating crossbred cows to evaluate the effect of heat-moisture treated (HMT) cassava (Manihot utilissima) supplementation on lactational performance and rumen fermentation of the animals. Twenty early lactating crossbred cows in the Cattle Breeding Farm, Thumburmuzhy were randomly assigned to four treatment groups which were T1 (control with 20 % crude protein, 68 % total digestible nutrients), T2 (T1 with 250 g/ day HMT0 cassava), T3 (T1 with 250 g/day HMT2 cassava) and T3 (T1 with 250 g/ day HMT3 cassava), with five animals in each group. Green fodder and paddy straw were used as roughages (ICAR, 2013). The result revealed that average daily dry matter intake (DMI), average body weights, fortnightly average daily milk yield of the animals among different treatments remain statistically similar (p>0.05) throughout the study. It was also observed that the rumen fermentation parameters such as rumen pH, total volatile fatty acids and rumen ammonia nitrogen were non-significant (p>0.05) among the dietary treatments. The study revealed that supplementing HMT cassava at the level of 250 g/day did not have any significant impact on the lactational performance of early lactating cows.
