Abstract

This research aimed to determine the population of the Black-Naped Fruit Dove (Ptilinopus melanasphila) by estimating population size, sex ratio, effective population, and inbreeding rate, providing a basis for ex-situ design considerations. Data collection employed survey techniques such as the line transect and concentration count point methods. Data analysis focused on determining population size, sex ratio, effective population, and inbreeding rate. The research was conducted in the Sula Islands, North Maluku. Observations and discussions were conducted separately for each location to obtain empirical and comprehensive data serving as a reference for further research. Results revealed the inbreeding rates at the research locations were observed as follows: Soamole village (1.42%), Wai Ipa village (1.56%), and Bega village (1.60%). Sex ratios were observed as follows: Soamole village (male : female ratio of 22.17 : 85.38), Wai Ipa village (male : female ratio of 19.48 : 73.78), and Bega village (male : female ratio of 19.61:80.39). Effective populations were observed as follows: Soamole village (22.39 heads), Wai Ipa village (16.48 heads), and Bega village (16.08 heads). The inbreeding rate is in the good category, while the population number, sex ratio and effective population are in the medium category, however habitat destruction and continuous excessive hunting can result in decline and extinction.

Abstract

Ptilinopus melanosphila and Chalcophaps indica, known as Puna birds among local people of the Sula Islands, North Maluku, Indonesia, while Treron aromaticus, known as Puna Giu, belong to the Columbidae family. These birds are frequently hunted for consumption due to the delectable taste of their meat. This study aims to examine the essential Omega-3 (n-3PUFA) nutritional content, utilizing these two avian species (Ptilinopus melanosphila and Chalcophaps indicia) as samples. Local perceptions consider these birds as identical, hence this study also provides insights into the disparities between the two species based on meat quality analysis. The analysis encompasses proximate analysis, fatty acids, and amino acids, conducted on 6 samples, each encompassing 3 breast meats. These samples were mixed and blended, followed by chemical analysis at the integrated laboratory of Universitas IPB Baranangsiang, with proximate analysis executed at PAU IPB. The results reveal that Ptilinopus melanosphila meat contains crucial nutrients for human consumption, specifically long-chain omega-3 unsaturated fatty acids (n-3PUFA), which are more abundant compared to Chalcophaps indica and several other meat products. The myriad of significant benefits offered by this avian species underscores the importance of recommending its preservation to parties engaged in ex-situ conservation efforts. Furthermore, it is advocated to stimulate the establishment of regional culinary businesses specializing in nutrient-rich Black-Naped Fruit Dove meat.

Abstract

Scarcity and high cost of raw materials for poultry feed are the main problems that can hamper poultry production. An alternative ingredient that can be used in feed is koro beans. The aim was to determine the effect of rations containing fermented jack beans, Rhizopus oligosporus, on the production performance and quality of quail eggs. The analysis used a completely randomized design consisting of 5 treatments; Each treatment was repeated 4 times and each replication consisted of 15 quail. Four types of rations contained fermented sword bean at 7.5, 15, 22.50 and 30% and the control ration did not contain fermented sword bean. The parameters observed included feed consumption, egg production, feed conversion, shell thickness, egg yolk color and egg yolk cholesterol. The level of fermented sword bean in the ration of laying quail did not have a significant effect (p>0.05) on feed consumption and eggshell thickness. However, egg weight, daily egg production, feed conversion, yolk color intensity and yolk cholesterol were significantly influenced by fermented treatment (p<0.05). Sword beans fermented by R. oligosporus can be used as a food ingredient in egg-laying quail feed formulations to increase the quantity and quality of quail eggs.
