Abstract
The study was designed with the objective to evaluate the feed intake (FI) and milk production (MP) parameters of different normal and QPM varieties green fodder in their pre and post cob stage in lactating Sahiwal cows. Four normal maize genotypes HTHM 5101, DHM 117, HM 5 and Shaktiman/900M Gold) and three QPM genotypes (HQPM 5, HQPM 7, HQPM 9/Vivek) were grown in different plots and were maintained under similar agronomic practices and climatic conditions. The pre-cob fodder was harvested after about 45-50 days of sowing. Then after harvesting of cobs post-cob fodder was obtained after 85-90 days of sowing. 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. Each group was fed with different variety of maize along with basal diet. Feed intake, milk yield and composition were assessed. As a result of this study, the DMI differ significantly (P<0.05) in different dietary groups in both the stages. It was significantly higher for DHM 117 variety and lowest for HTHM 5101 variety. The difference in DMI is mainly due to difference in the intake of green fodder. The milk yield (kg/d) and 4% Fat Corrected Milk (FCM) milk yield (kg) of Sahiwal cows fed on different varieties of maize fodder in both the stages was non significant. The parameters for milk composition viz. fat (%), protein (%), lactose (%), Solid Not Fat (SNF) (%) and total solids (%) were found to be non significant between different groups fed on different varieties of maize fodder during pre-cob and post-cob stages. Hence, it can be concluded that the milk yield and composition was not affected in lactating Sahiwal cows fed different varieties of maize fodder at pre and post-cob stages.References
