G., Makhdoom, Mathura, U.P. 281122 Received: January 2015; Revised: March 2015; Accepted: April 2015) Abstract The Jakhrana breed milk samples were from villages of Mathura and Agra, India (27 o 10´N, 78 -o 002´E and 169 m above MSL). Geologically the Institute is situated under Yamuna river semi arid soil. calcium content in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins and triplets multiple births was found to be 0.144±0.0020 and 0.150±0.0021, 0.140±0.0018 and 0.146±0.0019 and 0.136±0.0016 and 0.142±0.0017 per cent, respectively. It is observed from table that phosphorus content was significantly greater in farm samples than field rearing samples in all multiple births. Potassium percentage in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins and triplets birth was found to be 0.114±0.0007 and 0.115±0.0009, 0.111±0.0009 and 0.112±0.0009 and 0.108±0.0009 and 0.109±0.0009, respectively. The statistical analysis revealed that magnesium content was significantly (1%) higher in farm rearing samples than that of field samples in all multiple births. chloride percentage in the milk of Jakhrana goat breed under field and farm rearing samples in single, twins and triplets births was 0.107±0.0006 and 0.109±0.00054, 0.106±0.00061 and 0.108±0.00055 and 0.105±0.00061 and 0.107±0.00056, respectively. chloride percentage in the milk of Jakhrana goat breed under field and farm rearing samples in single, twins and triplets births was 0.107±0.0006 and 0.109±0.00054, 0.106±0.00061 and 0.108±0.00055 and 0.105±0.00061 and 0.107±0.00056, respectively. Selenium content was significantly greater in field samples than farm rearing samples in all multiple births. The highest selenium in percentage was recorded in single births in milk samples either field or farm rearing conditions. Key words: Jakhrana, goats, Effect of season, milk quality, field and farm. Introduction Goat which was known as “Wet nurse of infant” in the United Kingdom and “Poor man`s cow” in India was the first animal to be domesticated (Zeuner, 1963). Goat milk contains less lactose than cow’s milk, so is less likely to trigger lactose intolerance.

The milk also has a more similar makeup (percentage of fats, etc.) to human milk than cow’s milk. For these reasons, goat milk may be recommended for infants and people who have difficulty digesting cow’s milk. It is well established that milk yield in goats is influenced by litter size and lactation number. Milk yield is proportional to the mammary alveolar surface area (Richardson, 1973).
