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

Milk urea nitrogen (MUN) analys may be used as a signal potential problem in feeding program. The aim of this research was to know levels of milk urea nitrogen with different calving interval. This research was using purposive sampling in KUD Tani Wilis, Sendang, Tulungagung. The sample was obtained from breeder as much as 16 samples, grouped into 2 groups, group 1 calving interval ≤370 and group 2 calving interval ≥450. This samples tested in Surabaya laboratory of health (Balai Besar Laboratorium Kesehatan Surabaya). The result showed that MUN not signifcanly different with different calving interval (p>0,05). The conclusion of this research was MUN did not related with different calving interval.
