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.

VARIASI INDIVIDU TERHADAP KUALITAS SEMEN SEGAR KALKUN (Individual Variation in Turkey’s Fresh Semen Quality)

2025-07-12T13:51:56+00:00

Turkey is a kind of poultry with a special meat taste and higher meat protein than other poultry meat. Indonesia have limited turkey’s population because they has problem in reproduction efficiency is significant different in body weigh between male and female. Artificial insemination practices can be a solution for turkey’s reproduction efficiency problem. However, artificial insemination needs spermatozoa with good quality to fertilize the ovum. The individual gobbler (male turkey) could produce semen with different quality even though kept in same environtment condition. This study aim to evaluate individual variation impact to turkeys fresh semen quality. The fresh semen collected from 4 turkeys bronze breed in 8-12 months age, with massage technique two times a week. The macroscopic (volume, pH, colour, consistency) and microscopic (concentration, motility, viability, abnormality) examination become the observed variables. The result shows there are individual variation in variables are volume, pH, and sperm concentration from fresh semen. The result of this study can provide basic information about turkey’s fresh semen quality with individual variation.

The aim of this experiment was to determine the effect of feeding odot grass silage (Pennisetum Purpureum cv. Mott) with different levels of rice straw as absorbant on feeding behavior of Kacang goats. Four kacang goats, ranging from 1-1.5 year old with initial body weight of 20.2 kg-22.9 kg, were used in this study using Latin Square Design (RBSL) 4 x 4 with 4 treatments and 4 periods as replications. The treatments were JP0: 100% odot grass silage, JP10: 90% odot grass and 10% rice straw silage, JP20: 80% odot grass and 20% rice straw silage and JP30: 70% odot grass and 30% rice straw silage. The measured variables included the frequency and eating time, frequency and ruminating time, and frequency and resting time. The data obtained were analyzed using Analysis of Variance (ANOVA). The results showed that treatment had no significant effect (P>0,05) on the measured variables. The duration and frequency of feeding ranged from 4.34 to 5.42 hours and 16.50 to 19.87 times per day, duration and frequency of rumination ranged from 11.39 to 14.25 hours and 39.62 hours to 41.87 times per day, and the length and frequency of rest ranged from 5.43 to 7.56 hours, and 30.62 to 32.50 times per day. In conclusion, feeding odot grass silage with different levels of rice straw as an absorbant did not affect the feeding behavior of kacang goats.
