Seasonal Variations in the Milk Minerals of Jakhrana Goats under Field and Farm Rearing Conditions

In global scenario, India ranks second in terms of goat population and occupy top position in goat milk production. The study was conducted at the Central Institute for Research on Goats, Makhdoom, Mathura for documenting farm rearing condition. Milk samples were collected from Jakhrana goat under the farm and field rearing condition. Calcium percentage in the milk of Jakhrana breed under field and farm rearing conditions in summer, rainy and winter seasons was found to be 0.136±0.0019 and 0.142±0018, 0.140±0.0018 and 0.146±0.0019 and 0.144±0.0023 and 0.151±0.0018, respectively. It was also observed that phosphorus per cent in the milk of field rearing conditions was lower than that of farm rearing conditions in all seasons. Potassium percentage in the milk under field and farm rearing conditions in summer, rainy and winter seasons was found to be 0.110±0.0008 and 0.111±0.0008, 0.111±0.0008 and 0.112±0.0009 and 0.112±0.0007 and 0.113±0.0008 respectively. Magnesium percentage in the milk of Jakhrana goat breed under field and farm raring conditions in summer, rainy and winter seasons was found to be 0.0136±0.00014 and 0.0142±0.00016, 0.0140±0.00010 and 0.0146±0.00012 and 0.0144±0.00011 and 0.0150±0.00013, respectively. Highest chloride and selenium content in milk was found in winter season irrespective of field or farm rearing conditions. It was concluded that season had conspicuous effects on milk quality of goats under study.
