Abstract

Egg shape of second phase production (40- 70 weeks age) of layer bigger than egg shape of one phase production, but egg shell less thickly so than more perishable. On the other side 3.5-4% Ca in the diet only 50% can be absorbed in the intestinal. Ca absorption and Ca retention can be raised by supplementary zeolite in the diet. This experiment was conducted to observe the effect of supplying zeolite in the diet of 192 lohmann brown layer on the egg quality of second phase production. Different feeding treatment was carried out four each group. Layer in treatment 1 were fed control diet; treatment 2, a control diet + zeolite 1.5%; treatment 3, a control diet + zeolite 3%; and treatment 4, a control diet + zeolite 4%. 96 eggs sampel from layer experiment kept on 15 days. The result showed that supplementary zeolite in the diet was significantly ( P ≤ 0.05) increased the thickness of egg shell, significantly (P≤0.05) decreased of egg weight, significantly (P≤ 0.05) decreased air cell, significantly (P≤0.05) increased Haugh Unit (HU) score, and significantly (P≤ 0.05) decreased pH albumen of egg in the second phase production.

Abstract

The aim of this experiment was to find the effect of supplementation of zeolit and was to find the optimum level of zeolit in rations on quail performance. This experiment used 80 female Coturnix coturnix japonica of five weeks old with average body weight 145,44 ± 6,72 g (cv 4,62%). The data were analysed using Completely Randomized Design and polinomial ortogonal test. The treatments was divided to four supplementation zeolit rations treatment (0%,2%,4%,6%). Each treatment had five replication and each replication used four quails. Results of this study indicated that supplementation of zeolit (0 - 6%) in rations gave not significantly different (P ≥ 0,05) to feed consumption but gave significantly different (P < 0,05) to hen day egg production (Ŷ = 46,48 + 4,86X "“ 1,09 X2 ; 0≤ X ≤6 ; R2 = 0,90) and significnatly different (P < 0,05) to feed convertion (Ŷ= 4,85-0,44 + 0,10X 2 ; 0≤X≤6;R2 = 0,97). Level supplementation zeolit 2,22% was optimum to hen day egg production (51,86%) and level supplementation zeolit 2,09% was optimum to feed convertion (4,39).

Abstract

Circulation of synthetic antibacterial chemicals which is used continuously can cause resistance to bacteria. Alternative synthetic antibiotics research then comes up as an urgent need. Recently, the discovery of new antibacterial agents is looking for Actinomycetes. Actinomycetes are one of the active marine bacteria which produce secondary metabolites that could be used as antibacterial. The objective of this study was to evaluate the antibacterial activities of Actinomycetes symbiont with Halimeda macroloba, Gelidiella acerosa, and Turbinaria ornata in Pangandaran beach, Indonesia. A total of 41 Actinomycetes were isolated from 3 species of seaweed. Rep PCR amplification method was used to characterize and identify the relationship between samples. Primer BOX A1R (5’- CTACGGCAAGGCGACGCTGACGCTGACG-3’), 27F (5'-AGTTTGATCMTGGCTCAG-3') and 1492R (5'- TACGGYTACCTTGTTACGACTT-3') was used in amplification 16s DNA. Six isolates from the representative cluster dendogram were selected for secondary metabolites extraction using ethyl acetate solvent, meanwhile agar diffusion method was used as Antibacterial activity assay using E. coli, Proteus sp., and Enterobacter sp. as the bacterial test. The results showed that the activity of secondary metabolite extracts of Actinomycetes symbiont with Halimeda macroloba presented the highest inhibition zone on 3 bacterial tests. In the future, it could be a potential antibacterial agent against animal pathogenic bacteria.
