การศึกษาเปรียบเทียบต้นทุนและผลตอบแทนทางเศรษฐกิจของการเลี้ยงแม่สุกรพื้นเมืองภายใต้รูปแบบการให้อาหารที่แตกต่างกันในเขตจังหวัดสกลนคร | Comparative study on the economic cost and profit of the native sow raised under different feeding patterns in Sakon Nakhon province

Comparative study on the economic cost and profit in rearing native pigs was carried out under different feeding patterns for weaned piglet production. Feeding patterns were composed of 1) the use of feed based on rice bran mixed with other raw materials, 2) the use of feed based on rice bran together with food scraps from restaurants, and 3) the use of feed based on rice bran together with food scraps from the farmers’ kitchen. Thestudied data were collected individually by means of 59 farmer interviews, pig feed sampling and measuring the body weight of weaned piglets at the selling time. The result revealed that farmers had a high confidence in the native pig marketing. The number of weaned piglets was not sufficient for the market demand. Sows in the treatment 1 had higher protein intake and body condition score than those in the treatment 2 and 3 (P<0.05). The sow feed cost was the main cost and was different among treatments ranking from the treatment 1, 3 and 2, respectively (P<0.05). The total costs of the treatment 1 were higher than those of the treatment 2 and 3 as 3,139.2, 2,231.2 and 2,541.2 baht/litter, respectively (P<0.05). For the benefit, it was displayed that all of treatments had no difference in the total income. For calculated economic cost and profit per a weaned piglet at the selling time, the total cost of the treatment 1 was higher than that of the treatment 2 and 3 as 397.3, 280.6 and 328.6 baht/piglet, respectively, (P<0.05). The profit of treatment 1 was less than that of the treatment 2 and 3 as 192.0, 286.1 and 259.4 baht/piglet, respectively, (P<0.05). In conclusion, in the event of farmers are able to seek for another feed for native sows that is a low price (such as food scraps etc.), as substituted for the feed purchased from some other places, they will be able to get more the profit.
