Abstract

The present study aimed to determine the productivity and nutrient digestibility of sorghum (Sorghum bicolor (L.) Moench) fodder given different levels of urine fertilizer in various planting media and harvest times. The study was carried out in June - September 2020 and used numbu variety of sorghum planted hydroponically at fodder phase. This study used a 2x4 factorial completely randomized design with 4 replications. The first factor was the harvest time at 5 days (H1) and 10 days (H2). The second factor was the planting media that included water medium as an internal control (M1), 12.5 mL/L of urine fertilizer (M2) and 25 mL/L of water medium (M3), and urea 20 mg/L of water medium (M4) as the external control. The urine fertilizer was derived from Ongole crossbreed urine fermented for 21 days. The density of sorghum seeds in the planting medium was 2.5 kg/m2. The observed variables included plant productivity and nutrient digestibility in vitro. Data analysis used ANOVA and continued with Duncan's Multiple Range Test to determine significance. The results showed that the addition of urine fertilizer and harvest time had a significant effect on plant height, length of fresh leaf production, dry matter, organic matter, and crude protein compared to those of the internal control. The H2M3 treatment provides a comparable productivity effect with H2M4. Meanwhile, harvest time affected dry matter and organic matter digestibility. It can be concluded that 25.0 mL/L of urine fertilizer in planting medium and harvest time in 10 days were able to increase productivity, dry matter digestibility, and organic matter digestibility of sorghum fodder.

Abstract

An experiment was conducted at Kalikesur Farm, Kedung Banteng, Banyumas to investigate the reproductive performance of Saanen dairy goats after PGF2α injection on different body weights. This experiment included twenty female Saanen goats at 2-3 years of age, 2-3 kidding periods, and varying body weights of 30 to 55 kg. All goats were intramuscularly injected by 2 ml PGF2α (LutalyseTM, Pharmacia and Upjohn Company, Pfizer Inc) in a double injection pattern, with 11-day interval to perform estrous synchronization. The variables on reproductive performance such as estrus onset, length of estrus, and intensity of estrus were measured and monitored twice a day at 6-10 am and 3-5 pm. Descriptive statistics and correlation analysis were conducted. Results demonstrated that body weight performed strong correlations with estrus intensity (r = 0.66) while the time for the first estrus (onset) has a negative moderate correlation with body weight (r = -0.47), a negative weak correlation was recorded between body weight and length of estrus (r = -0.17). Based on the results obtained, it can be concluded that the body weight of goats in the estrus synchronization program can be used to be an indicator of reproductive performance, especially in estrus intensity. This can help farmers to predict estrus behavior after PGF2α synchronization.
