Abstract

This study aimed to describe the morphometric characteristics of the worker bee Tetragonula clypearis in Salut Village, District Kayangan, North Lombok Regency. The research material used was worker bee Tetragonula clypearis taken from 40 stup in two livestock groups, namely 20 stup in the Harapan Keluarga group and 20 stup in the Tunas Muda group in Salut Village, Kayangan District, North Lombok Regency. Each stup took three samples of worker bees for morphometric analysis (n=120). Morphological characters were observed under a stereo microscope connected to an Optilab camera. The character of T. clypearis is the thorax is black and hairy, and there are six hair bands on the mesoscutum and dark brown tibia. Metasoma has a variety of colours, ranging from pale yellow with black stripes, yellow and black, and pale yellow. The morphometric measurements included body length, head width, wing length, genna width, second flagellomere diameter, and body weight. The results showed that the seven morphometric measurement variables of the worker bee Tetragonula clypearis did not show significant differences (P>0.05) in the two cultivation groups. The value of the diversity coefficient <15% indicates that the morphometrics of the worker bee Tetragonula clypearis is uniform in both cultivation groups in Salut Village, District, Kayangan, North Lombok Regency.

Abstract

The success of artificial insemination in chickens is very dependent on sperm quality. Sperm temperature and diluent during storage can affect sperm quality. This study evaluated the quality of Bangkok chicken sperm diluted with 5% glucose and NaCl stored at 5 ⁰C and 26 ⁰C. The research design used was completely randomized. The data obtained were analyzed using a variance. The results showed that the motility of sperm preserved for 9 hours at 26 ⁰C with infused NaCl and Glucose 5% differed significantly (P< 0.05) with motility of 50±0.0% and 34±8.94%, respectively. While preservation under 5 ⁰C for 9 hours with NaCl, better than Glucose 5% (P<0.05) with motility of 58.00±10.95% and 38.00±10.95%, respectively. The viability of sperm preserved at 26 ⁰C with glucose 5% extender was better than NaCl (P<0.05) with a value of 58.93±1.27% and 33.43±1.27%, respectively. While preservation at 5 ⁰C of viabilities of sperm under Glucose 10% and NaCl were not significantly different (P>0.05) from values of 52.57±5.15% and 48.14±8.09%, respectively. The abnormality of sperm stored at 26 ⁰C and 5 ⁰C for 9 hours with NaCl and Glucose 5% were not different (P>0.05). Insemination using 100 million sperm with infused NaCl extender from 18 eggs produced 94.44% (n=17) fertility and 72.22% (n=13) hatchability. While insemination using infuse glucose 5% extender, 11 eggs produced 63.64% (n=7) fertility and 54.54% (n=6) hatchability. The infusing NaCl extender produced better sperm quality, fertility, and hatchability than glucose 5% at 5 ⁰C.
