Effect of pre-partum prilled fat supplementation on feed intake, energy balance and milk production in Murrah buffaloes
AIM To investigate the effect of pre-partum prilled fat feeding on dry matter intake (DMI), energy balance and milk production in Murrah buffaloes. MATERIALS AND METHODS Advance pregnant Murrah buffaloes were either received a dietary supplement of prilled fat at 100 g/day for 35 days pre-partum and at 150 g/day for 95 days post-partum (supplemented group [SG]) or did not receive fat suppleme...
متن کاملEstimates of genetic parameters for fat yield in Murrah buffaloes
AIM The present study was performed to investigate the effect of genetic and non-genetic factors affecting milk fat yield and to estimate genetic parameters of monthly test day fat yields (MTDFY) and lactation 305-day fat yield (L305FY) in Murrah buffaloes. MATERIALS AND METHODS The data on total of 10381 MTDFY records comprising the first four lactations of 470 Murrah buffaloes calved from 1...
متن کاملEstimation of genetic parameters of weekly test-day milk yields and first lactation 305-day milk yield in Murrah buffaloes
Aim: The aim was to estimate genetic parameters of weekly test-day (TD) milk yields and first lactation 305-day milk yield (FL305DY) in Murrah buffaloes. Materials and Methods: The data on 39059 weekly test-day milk yield (WTDY) records during first lactation of 961 Murrah buffaloes calved from 1977 to 2012 and sired by 101 bulls maintained in an organized farm at National Dairy Research Instit...
متن کاملEstimates of genetic parameters for total milk yield over multiple ages in Brazilian Murrah buffaloes using different models.
The objective of this study was to estimate variance components and genetic parameters for accumulated 305-day milk yield (MY305) over multiple ages, from 24 to 120 months of age, applying random regression (RRM), repeatability (REP) and multi-trait (MT) models. A total of 4472 lactation records from 1882 buffaloes of the Murrah breed were utilized. The contemporary group (herd-year-calving sea...
متن کاملEffect of microclimate alteration on milk production and composition in Murrah buffaloes.
AIM The aim of this study was to assess the effect of microclimate alteration on temperature-humidity index (THI), milk yield, and milk composition of Murrah buffaloes during summer for a period of 90-day from March to May-2014 at Buffalo Research Station, Venkataramannagudem, Andhra Pradesh, India. MATERIALS AND METHODS A total of 40 lactating Murrah buffaloes were selected having similar bo...
