RESPON KANDUNGAN ISOFLAVON DAIDZEINPADA LEGUM Alysicarpus vaginalis TERHADAP VARIASI DOSIS PUPUK FOSFOR (Response of Daidzein Isoflavone Content in Alysicarpus vaginalis Legume to Variations in Phosphorus Fertilizer Doses)

Sat, 12 Jul 2025 02:44:35 +0000

This study is grounded in the significance of daidzein as a phytoestrogen with potential to enhance livestock reproductive performance, while its availability in conventional feed ingredients remains limited. Alysicarpus vaginalis is a local legume species exhibiting relatively high phenolic and flavonoid compounds, including isoflavones, making this information crucial for developing phytogenic based functional feed. This research aimed to evaluate the effect of varying phosphorus fertilizer doses on daidzein isoflavone content in Alysicarpus vaginalis. An experimental study was conducted using a Completely Randomized Design (CRD) with five phosphorus dose treatments (0, 10, 20, 30, and 40 kg P/ha) and three replications. The methodology included: (1) isoflavone extraction via 70% ethanol maceration, (2) extract concentration using a rotary evaporator, and (3) quantitative analysis of daidzein content in phosphorus fertilized Alysicarpus vaginalis using High-Performance Liquid Chromatography (HPLC). Increasing phosphorus doses (0–40 kg P/ha) significantly (P<0.05) elevated daidzein content from 0.0922 g/100 g sample (control, 0 kg P/ha) to 2.9978 g/100 g sample at the highest dose (40 kg P/ha). Statistical analysis revealed a strong positive correlation between phosphorus dosage and daidzein accumulation (R² = 0.985). Phosphorus fertilizer application enhances daidzein production in Alysicarpus vaginalis, implying potential for functional feed development to support livestock health and productivity.

Mirah Chicken is a native chicken that has long been developed in Simalungun Regency and is thought to originate from the red jungle fowl (Gallus gallus). Currently, Mirah Chicken is used as a culinary ingredient known as Dayok Nabinatur. The population Mirah Chicken is yet known, but extensive Mirah Chicken breeders are still found in Simalungun Regency. To increase the population and make reproduction more efficient, mating with artificial insemination is applied to the Mirah Chicken population developed at the Faculty of Animal Husbandry, UHN. Therefore, the purpose of this study was to examine the quality of Mirah Chicken semen that will be used in the artificial insemination process. The basic population of Mirah Chickens was obtained from breeders in Simalungun Regency, where this basic population (G-D) has produced the first generation (G-1), which has reached a productive age of 8 months. The number of G-D and G-1 chickens used in this study was 5, respectively. The semen collection method was carried out by the massage method. The collected semen was evaluated macroscopically and microscopically in the livestock reproduction laboratory. The results of macroscopic evaluation showed that the volume of semen ranged from 0,14-0,18 ml/ejaculate, with a normal pH of 7,52-7,62, then the color of the semen was milky white, and the consistency was thick. The results of microscopic evaluation showed that the mass movement ranged from 1,4-2,0, and progress motility was around 72-74%. The sperm concentration parameter showed 8,12-10,47 x10⁹ spermatozoa cells/ml with an abnormality of around 18,2-19,0%. The results of statistical analysis showed that there was no difference between G-D and G-1 for all parameters and it can be concluded that the quality of Mirah Chicken semen is classified as normal and can be used for artificial insemination.

Thu, 07 Aug 2025 13:05:02 +0000

This research aimed to investigate the effect of pre-freezing time on the quality of frozen Landrace boar semen. Semen was collected from four 2-3 year old Landrace boars. The semen was evaluated macroscopically and microscopically. Subsequently, good quality semen was diluted in a basic extender, then subjected to a holding time of 2 hours at 27-28°C. The semen was then centrifuged at 2000 rpm for 15 minutes. The spermatozoa pellet was re-diluted with a Spermax extender, packaged into 0.5 mL straws, and equilibrated for 2 hours at 3-5°C. After equilibration, the straws were frozen by placing them 10 cm above the surface of liquid nitrogen at ±-110°C for durations of 3, 6, 9, and 12 minutes. The straws were then immersed into liquid nitrogen at -196°C. Thawing was performed by immersing the straws into a water bath containing water at 37°C for 30 seconds, followed by evaluation of semen quality. The results showed that pre-freezing time had no significant effect (P>0.05) on semen quality after dilution and equilibration. However, it had a significant effect (P<0.01) on the recovery rate, motility, and viability of spermatozoa after thawing, with the best treatment being 9 minutes. It was concluded that a pre-freezing time of 9 minutes resulted in the highest quality of frozen Landrace boar semen compared to other treatments.

This study aimed to evaluate the effects of water restriction and exercise on hematological parameters in Bali calves (Bos javanicus) fed a complete diet based on Clitoria ternatea. Four post-weaning Bali calves were subjected to four treatments: T0: control (ad libitum water and feed), T1: water restriction (50% of daily water intake), T2: exercise (30 minutes 2 km daily), and T3: a combination of water restriction and exercise. The experimental design followed a Latin Square arrangement with four treatments and four periods as replication. Blood samples were collected at the end of each period to assess erythrocyte, leukocyte, hemoglobin, and haematocrite concentrations. The results showed no significant effects (P>0.05) of water restriction or exercise on any of the measured hematological parameters. Erythrocyte, leukocyte, hemoglobin, and haematocrite levels remained stable across all treatments, with haematocrite values ranging from 34.23% to 35.58%. These findings suggest that feeding Bali calves a nutritionally balanced diet containing Clitoria ternatea can help mitigate the physiological impact of environmental stressors such as water restriction and exercise. The results highlight the resilience of Bali cattle in maintaining hematological health under challenging conditions, indicating their suitability for eco-farming systems in arid and water-limited regions. Further research is recommended to explore additional physiological responses and long-term effects on animal productivity.
