Abstract

Two types of packaging; polyvinyl cabinet bin (at the size of 60, 150 and 200 litres) and metal drum (at the size of 200 litres), were applied in this study to determine the suitable silage packaging materials for dairy farm at Kor Tao Sub-district, Paphayom district, Phatthalung province. Two types of grass, Napier (Pennisetum purpureum) aged 30 days and Ruzi (Brachiaria ruziziensis) aged 45 days were used to study. After 30 days of fermentation, the yield of Napier silage in the polyvinyl cabinet bin at the size of 60, 150 and 200 litres and metal drum were 97.4, 97.6, 98.9 and 98.5% of fresh weight, respectively whereas the yield of Ruzi silage were 97.2, 97.2, 97.8 and 98.2% of fresh weight, respectively. Silage from all types of container had green-yellow colour and normal smell as the same with typical silage. When consider the cost of silage production, the Napier silage had lower than the Ruzi silage in all container types. In addition, Napier silage when packed in 200 litres polyvinyl cabinet bin showed the lowest cost (2.33 Baht/kg of fresh grass). All participating farmers appreciated in the quality of the silage and concur to use the 200 litres size of polyvinyl cabinet bin.
