| dc.description.abstract | ABSTRACT : A study was conducted for 120 days using 18 crossbred pigs to study the effect of Azolla pinnata on growth, haematology and carcass traits during growing and finishing periods. Dried azolla contained 75.73% OM, 23.49% CP, 3.7% EE, 14.7% CF, 33.84% NFE, 24.26% TA, 2.58% calcium and 0.26% phosphorus. The study revealed that the cumulative weight gains were 21.31 ± 1.82 kg, 21.01 ± 0.53 kg and 21.07 ± 2.69 kg in grower pigs fed G1, G2 and G3 rations, respectively, while, the same were 21.14 ± 1.18 kg, 20.84 ± 0.82 kg and 20.81 ± 1.09 kg in pigs fed F1, F2 and F3 rations, respectively and the difference between the groups were non-significant (P < 0.05). The average daily gain in growers and finishers statistically did not show any significance (P < 0.05). The ADG in pigs fed with G1, G2 and G3 rations was 0.36 ± 0.06, 0.35 ± 0.05 and 0.35 ± 0.03 kg, respectively and in pigs fed with F1, F2 and F3 was 0.35 ± 0.07 kg, 0.34 ± 0.06 kg and 0.35 kg ± 0.05 kg, respectively. It was evident that FCR in pigs fed with control ration was high when compared to the other two groups of pigs fed with rations containing azolla as a feed ingredient. The haematological parameters viz., PCV, Hb, RBC, WBC and MCHC showed no significant (P < 0.05) difference between the means of the three different ration fed groups. The carcass characteristics such as carcass weight, dressing percentage, carcass length, loin eye area, backfat thickness, weight of edible and inedible offals, meat and bone percentages showed no significant difference among the pigs fed different rations except for fat percentage which was found to be higher in pigs fed with control diet than in pigs fed with test rations. A higher dressing percentage was noticed in T3 pigs (83.45 percent) followed by T2 pigs (81.37 percent) and T1 pigs (81.18 percent). Loin eye area was found to be higher in T3 with 33.76 cm2 followed by T1 with 30.5 cm2 and then T2 with 28.25 cm2 and the mean backfat thickness of pigs from T1, T2 and T3 groups was 2.00, 1.94 and 1.88 cm, respectively. The feed cost per day was highest in the control group G1 (` 24.50) followed by G2 (` 22.55) and G3 (` 20.75) groups and likewise, it was higher in pigs fed with F1 ration (` 26.39) than in F2 (` 24.45) and F3 (` 22.90) ration fed pigs and the differences were statistically significant (P < 0.05). The unit cost of fresh azolla produced was ` 0.56 and of dried azolla was ` 5.65. The livability was cent percent in all the three groups and inclusion of azolla upto 20 % in the swine rations had no deleterious effect on the performance of growers and finishers. Cost per kg gain was found to be higher in pigs fed with conventional G1 (` 68.06) ration than in pigs fed with G2 (` 64.42) and G3 (` 59.28) rations and similarly, during finisher period it was higher in pigs fed with conventional F1 (` 75.40) ration than in pigs fed with F2 (` 71.91) and F3 (` 65.42) rations. | en_US |
