Abstract

The aim of this research was to investigate the effect of probiotics Bacillus subtilis on feed efficiency and egg mass of laying hens. This research was using 36 of 38 weeks-old laying hens Isa Brown strain. The concentration of probiotics B. subtilis was 1 x 109 CFU/ml, there were three kinds of treatments, P0 (without given probiotics B. subtilis), P1 (given 0.1 gram of probiotics B. subtilis per kg of feed), and P2 (given 0.2 gram of probiotic B. subtilis per kg of feed). The results of feed efficiency, the provision of probiotics can provide a significantly different values (p <0.05) between treatments either P0, P1, or P2. Provision probiotics P1 showed the highest value of feed efficiency (81.72 ± 5.28), while the lowest value at P0 was (64.06 ± 3.30). The results showed that there were significantly different in egg mass values (p <0.05) between treatments both P0, P1, and P2. Probiotic P2 shows the highest value (53.30 ± 2.13), while the lowest egg mass value of probiotics is as much as P1 (40.83 ± 4.73). Based on the results of this study it can be concluded that the B. subtilis probiotics both at a dose of 0.1 gram / kg of feed and a dose of 0.2 gram / kg of feed can affect the growth performance of laying hens.

Abstract

The aim of this research was to observe the influence of palm kernel meal and íŸ-Mannanase on laying hens. Laying hens up to 2500 birds were reared in opened-house cage fed with commercial feed substituted with palm kernel meal and íŸ-Mannanase. All hens were divided into five groups in an order P0 as control group, groups without enzyme which are P1 with 7% palm kernel meal and P2 with 14% palm kernel meal, groups with íŸ-Mannanase which are P3 7% palm kernel meal and P4 with 14% palm kernel meal. The observed variables are feed intake, feed cost, egg weight, egg mass, feed conversion ratio, hen day production, and mortality rate. The results indicated that threr are no significant difference from all variables. The percentage of palm kernel meal for 14% with íŸ-Mannanase cannot give any influence on laying hens productivity.

Abstract

The aim of the study was to determine the effect of the use of probiotic lactic acid bacteria (Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, and Bifidobacterium sp) on feed efficiency, carcass weight and carcass percentage in broiler ducks. Probiotics lactic acid bacteria produce bacteriocins and organic acids that inhibit the growth of pathogenic microbes in the digestive tract of poultry, so that the intestinal villi of broiler ducks are healthy. Besides that, probiotics are able to reduce cholesterol levels in meat when consumed by humans and can improve health. This study used 48 peking ducks. The probiotics of Lactic Acid Bacteria used were a concentration of 1.2 x 108 CFU/ml. In this study there were four different treatments, namely P0 (without probiotics), P1 (given 1 ml probiotics/liter drinking water), P2 (given 2 ml probiotics/liter drinking water) and P3 (given 3 ml probiotics/liter of drinking water). The results of the feed efficiency study showed that there was a significant difference (p<0.05) in the P0, P1, P2 and P3 treatments. The highest feed efficiency was at P3 (33.81%) while the lowest was P0 (30.84%). The results of the study on carcass weight indicated that the probiotics tended to be higher than those who were not given probiotics but statistically not significantly different (p>0.05). The highest carcass weight was P3 (1749.92 g) and the lowest was P0 (1709.25 g). The results of the study on the percentage of carcass weight showed a significant difference (p<0.05) in both P0, P1, P2 and P3 treatments. The highest percentage of carcass weight was at P3 (64.60%) and the lowest was P0 (60.96%). It can be concluded that the administration of probiotics lactic acid bacteria (Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, and Bifidobacterium sp) at a dose of 1 ml/liter of drinking water, 2 ml/liter of drinking water and 3 ml/liter of drinking water can affect feed efficiency and the percentage of duck carcasses. but has no effect on the carcass weight of broiler ducks.
