abstract
The study was conducted to calculate the economics of Azolla production and its effect on feeding cost of swine. Azolla pinnata was included as a protein replacer in the concentrate feed at the rate of 15% in the feed of growing pigs. The duration was 150 days, 14 growing crossbred Large White Yorkshire pigs randomly divided into 2 groups (G1 and G2) with seven pigs in each group. The quantity of Azolla required for the experiment was grown and the unit cost of fresh Azolla produced was (रु) 1.36 and dry Azolla was (रु) 13.6. Average total feed intake (kg) per pigs during the experimental period in G1 and G2 was 284.84 and 288.59, respectively. Total feed cost in G1 and G2 (रु) was 6096.00 and 5838.00, respectively. The total live weight gain (kg) during the experimental period 54.13 and 58.22 in G1 and G2 groups, respectively. The total cost (रु) per kg body weight gain was calculated as 112.62 and 100.27 in G1 and G2 groups, respectively. Azolla pinnata is unconventional protein source 15% in diet reduces the feed cost in swine rearing.
