Abstract

The aim of the study was to evaluate the effects of inclusion plant source of n 3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the diets of layers on production performance and physical quality of eggs. A total of  125 Hy-Line Brown hens (38 weeks old) were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI) measured weekly and feed consumption ratio (FCR) was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment) were collected to analyse physical quality of eggs. The data were analyzed using Analysis of Variance (ANOVA). Differences between treatment means were further analyzed using Duncans New Multiple Range Test (DMRT). Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU). The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs.

Abstract

Losari Village is one of the villages located in Rawalo District, Banyumas Regency, Central Java which is included in the Serayu Watershed area. The location of Losari Village is in a lowland area with an altitude of around 50-100 meters and is included in the middle of the Serayu Watershed. Changes in land use due to urbanization and intensive agricultural activities in recent years have triggered various environmental problems that have an impact, especially on changes in the potential density of vegetation and water conditions. The need for monitoring of changes in structure and composition that are carried out periodically in order to prevent an increase in land and water use. The purpose of this paper is to determine the density of vegetation in Losari Village in 2022-2024 and the potential density of vegetation on groundwater conditions in Losari Village. Data collection methods use observation, documentation, and questionnaires. The data analysis technique used is quantitative descriptive and data retrieval of vegetation density from Lansat-8 satellite imagery and processed using the ArcGis application and checking the quality of groundwater in Losari Village, Rawalo District, Banyumas. The vegetation density of Losari Village in 2022-2024 shows that the increasing population and development of an area can affect the vegetation density in the area. Reduced vegetation density will affect the environment, especially groundwater conditions. The conclusion in the relationship between vegetation density and groundwater conditions shows a fairly significant pattern where areas with denser vegetation tend to have better groundwater reserves.
