Utilisation of potato processing industry waste for making feed pellet: Compounded livestock feed pellets
were prepared by incorporating potato pulp and potato chips of processing industry waste. Up to 30 % grain component was replaced by potato component. The feed samples were evaluated for their quality and trials on animal feeding were conducted. Five to seven per cent increase in milk yield of cattle was observed due to the feed.
Utilisation of unmarketable potatoes for making feed pellets: In order to utilize unmarketable potatoes
these were pulped and dewatered mechanically. It resulted in reduction in moisture content from 75 - 80 % to 40 - 45 %. The pulp obtained with reduced moisture content was directly mixed with other feed ingredients for pelletization. The feed prepared with dewatered potatoes contained 20 - 22 % of moisture. Proximate composition of feed prepared with 30 % dewatered potatoes was analysed. The feed pellets had 11.40 % moisture, 13.86 % protein, 4.96 % fat and 6 % ash. The neutral detergent fibre, acid detergent fibre, cellulose and lignin were observed to be 35, 13.4, 13 and 2.5 %. The strength of the pellets was observed to be 0.83 MPa. These samples were also subjected to animal feeding trials. Aflatoxin content of all the feed samples was analyzed using AOAC 990.33 method. The aflatoxin B1, B2, G1 and G2 were observed to be non-detected with MDL (Method Detection Limit) 30 ppb.
