The objective of the study was to evaluate the nutrient intake and digestibility of four different varieties (HTHM 5101, DHM 117, HM 5 and Shaktiman/900M Gold) of normal and three (HQPM 5, HQPM 7, HQPM 9/Vivek) HQPM fodder at pre-cob and post-cob stage in lactating sahiwal cows. Thirty-two multiparous Sahiwal cows in early to mid lactation were selected from herd maintained at ILFC, Mathura and were divided into eight group of four animal each. The seeds of experimental varieties were procured from International Maize and Wheat Centre (CIMMYT) New Delhi and the fodders were cultivated under identical conditions in different plots.. Each group was fed with different variety of maize along with basal diet.. Two digestibility trials of seven days were conducted both at the end of feeding of pre and post cob stages of fodder respectively.. The variety DHM 117 have shown higher (P<0.05) DCP and TDN intake at both pre and post-cob stages of the fodder. The digestibility of DM, OM and CP was significantly (P<0.05) higher for DHM 117 whereas, in post cobs stage the normal varieties (DHM 117, HM 5, and HTHM 5101) exhibited higher DM and OM digestibility. However, the digestibility of DM, OM and CP was lower for HQPM 9 and HQPM 5 varieties at both stages respectively. From the present study varietal effect was observed and the variety DHM 117 have shown higher intake and digestibility at both pre and post-cob stages however long-term study with large number of animals is advisable. for recommendation.
