Abstract
A study was conducted to evaluate the efficacy of various herbal agents as post
milking teat dips on bacterial load, somatic cell count, milk yield and milk composition
and teat condition score in lactating dairy cattle for 28 days period. A total of 25 lactating
dairy HF crossbred cows of 6-8 years age were divided in to five groups each having five
cows; T1 (Control fresh clean water), T2 (one per cent potassium iodide), T3 (Aloe vera
gel), T4 (turmeric paste) and T5 (neem oil). Among the treatment groups, group dipped
with Aloe vera gel and neem oil was significantly (P≤0.05) effective in reducing somatic
cell counts, milk pH and teat skin condition score and increasing the per cent of milk
compositional parameters viz., SNF, lactose and protein. Milk fat was significantly
(P≤0.05) lower in group dipped with neem oil on day 28. Bacterial counts (log10) of
Staphylococcus and E. coli (CFU/ml) were significantly (P≤0.05) higher in control group.
Counts of Staphylococcus (log10) (CFU/ml) were significantly (P≤0.05) lower in group
dipped with neem oil. Counts of E. coli (log10) (CFU/ml) were significantly (P≤0.05) lower
in treatment groups other than control group. There was no consistency in milk yield,
though there was a significant (P≤0.05) difference on day 7 and 14. On day 21 and 28, milk
yield was not affected by any of the treatments applied. No significant (P>0.05) difference
was observed in teat orifice condition score and counts of Streptococcus (log10) (CFU/ml).
It could be concluded among the herbal agents used, groups dipped with Aloe vera gel and
neem oil performed better compared to other treatment groups.
