EFFECT OF DIFFERENT TREATMENTS OF PRE-MILKING TEAT STIMULATION ON YIELD AND COMPOSITIONAL QUALITY OF RAW MILK IN CROSSBRED CATTLE
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 58
Abstract
The present study was designed to evaluate the effect of different treatments of pre-milking teat stimulation on yield and compositional quality of raw milk in crossbred cattle at SHIATS dairy farm, Allahabad. In treatment T1, T2, T3 and T4, pre-milking teat stimulation was done by milker's hand, latex made hand gloves, cotton duster and muslin cloth, respectively. Milk samples were evaluated for milk yield, fat, SNF, acidity and specific gravity in each of the treatment groups. Milk yield was significantly (P<0.05) higher in T4 as compared to other three groups. The percent acidity was significantly (P<0.05) higher in T1 as compared to T4. Other parameters did not show any significant difference among all the treatment groups. In treatment T1, fat was significantly (P<0.05) correlated with SNF and SNF was significantly correlated with specific gravity (P<0.01) and specific gravity was negatively (P<0.02) correlated with acidity. In treatment T2, SNF was significantly correlated with fat (P<0.05) and specific gravity (P<0.01). In treatment T3, milk yield was positively correlated with fat percent (P<0.05) and SNF was positively correlated (P<0.01) with specific gravity. In treatment T4, milk yield was positively (P<0.05) correlated with SNF. It is concluded that pre-milking teat stimulation with latex made hand gloves results in better milk yield as compared to other stimulations and acidity in milk was higher when teat was stimulated by milkers hand than when stimulated with latex made hand gloves.
