Abstract

Tokay gecko (Gekko gecko) is a large-sized gecko from the genus of Gekko, which is most commonly found from South Asia, southern China, and Southeast Asia. In Indonesia, these species are common to inhabit human-modified habitat in Sumatera, Borneo, Java, Bali, Lesser Sundas, Sulawesi, and Moluccas. In recent years, the demand for Tokay gekko with high use-value in both national and international markets has increased, one of which is used for traditional medicine. This situation raised the concern on the decreasing of the wild population and the validity of captive breeding programs that produced a large number of individuals. Several reports had estimated millions of individuals have been exported from Indonesia either legally or illegally, however, the exact number never been reported. The purpose of this study is to evaluate the trend on the harvested Tokay gecko and its origin based on the source code information. The data were collected from government records, including specimens harvested from the wild and specimens produced from captivity during 2013 - 2018 (six years). The results showed that the legally exported specimens were sourced from wild (W) and captive breeding (C or F). The total numbers of individuals exported from the wild harvest are 97.146, and all export realization is below the wild harvest quota. However, there are the large numbers of individuals exported and declared as specimens produced from the captive breeding facilities (6.965.000 with source code F, and 1.236.000 with source code C). More importantly, the high level of specimens produced from captive breeding facilities is unlikely to match with the biological capacity of this species. Therefore, we predict that specimens labeled captive breeding were likely sourced from the wild.

Abstract

This study aimed to detect genetic diversity associated with litter size traits of the P21-activated kinases (PAK1) gene in Senduro and Boerawa goats using the PCR-RFLP method. The restriction enzyme used is MSP1 (C*CGG). A pair of primers used in this study, namely Forward ((5'-GCTCAGTGTTGTATTAGCAG-3') and Reverse (5'- CAAGATATAAAGCACAGCCG-3') product length 713 bp (access code ENSCHIG00000003071). The samples used in this study consisted of 80 samples of Senduro goats and 20 samples of Boerawa goats from UPT PT-HMT Singosari, Malang Regency. The results showed that the PAK1 exon 9 gene in Senduro goats and Boerawa goats UPT PT-HMT Singosari was uniform (monomorphic), it was because all samples had GG genotype and G allele frequency of 100%. In conclusion, the PAK1 exon 9 / MSP1 gene is monomorphic and does not associate with litter size in Senduro goats and Boerawa goats, so it cannot be used as a genetic marker.

Abstract

The research aims to analyze the production potential and opportunities to increase the productivity of each cross-bred animal based on its quantitative characteristics. The livestock material used in this research was 50 Sera chickens (Sentul chickens x Arabian chickens) and 50 Mera chickens (Merawang chickens x Arabian chickens). The research was carried out by raising chickens from DOC to 3 months of age. The quantitative data involve body weight, weight gain, and body measurements (Head Length, Head Circumference, Head Height, Neck Length, Neck Circumference, Wing Length, Back Length, Back Height, Chest Length, Chest Width, Shank Length, Shank Circumference, Length Third Finger and Pubic Bone Distance). The quantitative data that has been observed is then analyzed through the t-test. Then, PCA is used to identify body shape and size determinants in Sera and Mera chickens. Statistical analysis was carried out using Minitab software version 21. The results obtained showed that the body weights of Sera and Mera chickens were significantly different (p<0.05) from DOC to 3 months of age. A significant increase in productivity in crosses between Sentul chickens and Arabian chickens and Merawang chickens with Arabian chickens occurs starting at 1-2 months. Sera and Mera chickens' body sizes differed significantly (p<0.05). The total diversity of PC1 in Sera chickens was 79.8%, and in Mera chickens, it was 70.6%. Meanwhile, the total PC2 diversity of Sera chickens was 17.7%, and Mera chickens were 7.9%. In conclusion, Sera chickens have the highest quantitative characteristics compared to Mera chickens, and the highest body weight gain occurs at 1-2 months in both Sera and Mera chickens.  Based on principal component analysis. The body size characteristic of Sera chickens is shank length, while in Mera chickens, it is chest length. The distinct shape of Sera chickens is body height, while in Mera chickens, it is shank length.
