Abstract

This study aims to determine the effect of probiotic administration encapsulated on the cholesterol content of egg laying eggs. Probiotics are given to laying hens (phase layer), once a day for 4 weeks orally. In this study a completely randomized design (CRD) was used with three treatments, namely, probiotic encapsulated lactic acid bacteria (BAL) (E1), commercial probiotics (E2), and without probiotics (E0) with 4 replications. The variables observed in this study were encapsulated probiotic viability, egg weight (g), egg index (%), and total egg cholesterol content (mg / g). The results showed that the viability of probiotic bacteria decreased by 3.34 cfu / g after 4 weeks of storage at 4OC. Average egg weight at E0; E1; and E2 are 62.63 g, 62.67 g, and 64.15 g. Average egg index at E0; E1; and E2 are 71.13%, 75.54%, and 77.2%. The average cholesterol content at E0; E1; and E2 is 3.75 mg / g, 3.25 mg / g and 3.25 mg / g. The administration of encapsulated probiotics did not affect the quality of egg weight but it affected the egg index and total cholesterol content of egg laying eggs.

Abstract

Mangrove ecosystem is a habitat of various fauna, especially macrozoobenthos. The changing vegetation of the mangrove ecosystem will influence the abundance of macrozoobenthos. This study was conducted in April-August 2019 and aims to analyze the dominance and density relations of mangrove vegetation against the abundance of Macrozoobenthos on the Pagkajene coast. The research location is conducted on three stations, each station is divided into two sampling areas, and on each sampling area is placed six sampling points. Data collection of mangrove vegetation is used with a multilevel plot method and Macrozoobenthos using a plot 50x50 cm. correlation the dominance and density of mangrove vegetation towards the abundance of macrozoobenthos used linear regression analysis. The results of the study gained that the mangrove vegetation dominancy positively affects to the abundance of macrozoobenthos but insignificant. Meanwhile, the density of mangrove vegetation significantly negatively affects to the abundance of macrozoobenthos.
