Abstract

The side effect of fatty acid oxidation during lippoprotein synthesis is the release of oxygen in the tissue called reactive oxygen species (ROS). Metabolic stress in Joper brooders due to an imbalance between ROS and antioxidants causes a decrease in hatching egg production and quality. Therefore, research is needed to improve the reproductive performance of Joper broodstock by combining vitamin E-selenium supplementation and metabolic energy. This study used 200 hatched eggs resulting from a cross between 60 weeks old Sentul males and 35 weeks old ISA BROWN laying hens that had been treated. This study used a Factorial Completely Randomized Design (CRD) (2 x 4). The first factor is the energy level (2700 and 2800 kcal/kg) and the second factor is the dose of vitamin E-selenium supplementation (0, 25, 50, 75 and 100 ppm). Selenium dosage is 1ppm/mg vitamin E. The interaction between vitamin E-selenium supplementation and energy had a very significant effect (P<0.01) in increasing DOC weight. The single factor energy level and vitamin E-selenium supplementation significantly (p<0.05) in reducing embryo mortality and increasing hatchability, while fertility and eggshell quality were not affected by the two treatment factors. The conclusion of this study is the interaction between vitamin E-selenium supplementation and energy levels can increase the weight of Joper's DOC, while the single factor of vitamin E-selenium supplementation and energy levels can reduce embryo mortality and increase hatchability. The best interaction with 100 ppm vitamin E-selenium supplementation and energy 2800 kcal/kg.

Abstract

This study was done to determine impact of aging on sperm quality of Sentul roosters. Materials used in this study were Sentul males aged 48, 58, 68 and 78 weeks, NaCl, eosin and aquades. Semen was collected by abdominal massage method. Completely randomized design (CRD) was applied in this study with 4 treatments in 5 repetitions. Statistical analysis showed that increasing age of rooster had a very significant effect (p0.01) on decreasing semen consistency, mass motility, spermatozoa concentration and increasing spermatozoa motility. Aging in Sentul roosters affected semen volume significantly (P0.05)  but  did not significantly affect (p0.05): semen pH, live spermatozoa, and spermatozoa abnormalities. Average volume of semen produced in this study ranged from 0.54-0.88ml; semen pH 6.80-7.12; mass movement score 1.60-3.00; spermatozoa concentration 2.76-4.86 x109/ml; spermatozoa motility 66-79%; Live spermatozoa 91.75-93.10%, and spermatozoa abnormalities 1.75-2.51%. Semen from Sentul males aged 48-68 weeks had a thick consistency and cloudy white in color. At the age of 78 weeks, the consistency varies from thick, medium and liquid. The color of semen in Sentul males aged 78 weeks also varied from clear white to cream. It is concluded that aging in Sentul roosters causes reproductive disorders which are characterized by low sperm quality. The best quality spermatozoa were produced by Sentul roosters aged 58-68 weeks.
