Abstract
The present study undertaken to study factors affecting the milk somatic cells of dairy
animals reared under farm and field conditions. A total of 192 dairy animals were
included from NDRI farm and adjoining villages (farm) of Karnal, Haryana and divided
into 96 cows (48 Sahiwal and 48 KF), 48 buffaloes, 48 goats and further subdivided into
2 groups i.e. farm (n=24) and field (n=24). A proforma was prepared for survey on field
which included different questionaries regarding managemental practices followed by
farmers for clean milk production. Milk from different dairy animals was collected
hygienically and evaluated for milk composition and somatic cell count (SCC). Changes
in milk composition and somatic cell count were evaluated to observe the effect of
different parity i.e., primiparous, and multiparous and different managemental practices.
Milk somatic cell counts were significantly lower in primiparous as compared
multiparous cows (Sahiwal and KF) in both farm and field conditions. While average
range of milk somatic cell counts in Murrah buffaloes were significantly lower as
compared to cows.Milk somatic cell counts in farm goats were higher than that of
field.With increase in SCC there was no significant variation in fat percent of dairy
animals. However, protein, EC and pH increased, whereas SNF and lactose
decreased.Washing of animals, hands, udder and teats and collection vessels before
milking were followed under field conditions, whereas washing of udder after milking,
teat dipping and screening of udder for mastitis were not followed. This study indicated
that milk SCC gets influenced by the different managemental practices that are being
followed for lactating dairy animals. Further good health, hygiene and clean milking
practices would help to maintain the quality of milk produced under farm and field
conditions.
