ABSTRACT

The study was carried out to determine the efficacy of neem oil and common salt as curing agent to control biodegradation of green hides. A total number of nine intact hides were obtained from slaughtered cattle of 4 and 4 1/2 years of age. Three types of curing treatments were employed using various concentrations of neem oil and common salts. T1 provides 40% neem oil and 10% common salt, T2 includes 10% neem oil and 20% common salt and T3 contains 10% neem oil and 10% common salt. The hides of each treatment were kept at 10, 20 and 30 days storage periods. After every 10 days of storage hides were subjected to bacteriological examinations. Storage properties of hides were also determined by the evidence of spot, color changes and sliminess of the skin. The mean value of total bacterial count was recorded lowest 6.96±0.30 in T2. Total coliform counts were found almost nil in T2. None of the treatment was found effective to control the growth of staphylococci. No signs of bacterial spoilage in hides were evident in T1 upto 10 days of storage. However indication of some sliminess could be noticed in the regions of neck and butt after storage of 20 and 30 days. T2 exhibited more or less changes in color on the 10th day of storage and sliminess was noticed fairly distributed on the neck and belly regions on the 30th day of storage. T3 exhibited some noticeable changes in the butt region. Putrefactive action started and there was indication of tissue changes, which could be marked, from the 10th day of storage. At the butt region foul odor was perceptible and few hair slip was evidenced on the 30th day of storage. It is concluded that the treatment using combination of neem oil and common salt showed antibacterial activity against the growing contaminating putrefactive organisms but less effective against halophiles.
