Abstract

This study was aimed to assess the effect of the addition of putak  meal (as a source of carbohydrates) and rumen content (as a source of enzymes) in the making of C. odorata silage to the total content of tannins and nutrient content of C. odorata silage. The treatments were: CO (C. odorata), COP (C. odorata + 10% of putak meal), COPR5 (C. odorata + 10% of putak meal + 5% of rumen content), and COPR10 (C. odorata + 10% of putak meal + 10% of rumen content). The experimental design used was Completely Randomized Design, with 4 x 2 factorial patterns. The first factor was the treatment (CO, COP, COPR4, COPR10) and the second factor is the silage fermentation time (0 days and 21 days). Each treatment was replicated 4 times. The variables measured were concentration of total tannin content and nutrient content. The results showed that the addition of (10% of putak meal and 10% of rumen content) decrease total tannins of the silage by 15.50%. The nutrient content (OM and OP) increased by 3.45% and 41.81% respectively as well as a decline in crude fiber 3% when compared to the silage without additives. Fermentation time of C. odorata silage for 21 days produced the best quality silage fermentation time compared to 0 days.

Abstract

Plantation by-products can be used as livestock feed with proper processing, optimizing the feed efficiency of palm kernel cake (PKC), empty oil palm bunch (EOPB), and acacia sawdust (AS). This study aimed to improve the usability of the byproducts as alternative feed through the Pleurotus ostreatus fermentation process. To this end, a 3×3 factorial, completely randomized design was applied. Factor A was the type of substrate, P1 = PKC, P2 = EOFB and P3 = AS. Factor B was the fermentation period, T1 = 0 d, T2 = 30 d and T3 = 60 d. The collected data were analyzed using analysis of variance (ANOVA), and the significantly different result was further tested using Duncan Test. The observed variables include Neutral Detergent Fiber (NDF), acid detergent fiber (ADF), hemicellulose, pH value, dry matter digestibility (DMD), organic matter digestibility (OMD), N-NH 3 , and volatile fatty acids (VFA). The study result showed that P.ostreatus mushroom in various substrate types did not significantly affect the fiber fraction of NDF, ADF, and Hemicellulose. This study also found that the interaction of substrate type and fermentation duration significantly affects dry matter digestibility, organic matter digestibility, N-NH 3 production, and VFA values. This study concluded P. ostreotus increased the nutritional value and digestibility of the by- product from plantation processing. The best fermentation duration was 60 d PKC was found to have the highest digestibility value, and the best interaction was found in PKC with 60 d of fermentation.

Abstract

Butterfly pea (Clitoria ternatea L.) a high-quality legume that is rich in protein and grows on various soil types with a pH range of 5.5-8.9. This experiment was conducted to get the level of tolerance of butterfly pea plants to stress acidity at different levels through tissue culture technique. The study was designed using a complete randomized design with 6 treatments with the different levels of AlCl3 addition using Murashige Skoog (MS) media with 20 replications (P0 (0 ppm AlCl3), P1 (100 ppm AlCl3), P2 (200 ppm AlCl3), P3 (300 ppm AlCl3), P4 (400 ppm AlCl3), and P5 (500 ppm AlCl3)). Data were analyzed using analysis of variance (ANOVA), and if there was a significant difference, data were further analyzed using Duncan’s multiple range test. The variables observed were acidity media changes, plant height gain, number of leaves, number of branches, number of tillers, percentage of leaves withering, and leaf color. The results showed that the butterfly pea plant has mechanism of adaptation to acid stress on the parameters of plant height gain and number of leaves at the end of the observation. However, the level of plant tolerance on the parameters of the number of branches and the number of tillers was ≤ 300 ppm (pH 3.73).

Abstract

Gamma-ray irradiation can induce plant mutations, resulting in stable genetic changes that persist in future generations. This study aims to assess the morphological characteristics of the potential mutant of Hedge Lucerne (Desmanthus virgatus) that has developed adaptation to high salinity conditions as a result of irradiation using gamma-ray. A total of 36 candidate mutants first generation (M1) of D. virgatus were used in this study, and they had developed adaptation to high salinity conditions (8.4 dS/m) and were observed 64 wk after planting. The collected data underwent a descriptive statistical analysis and succeeded by applying the Shapiro-Wilk test to assess the normality of the data distribution. A concentration index greater than one (>1.00) signifies a high value of the plant’s morphological characteristic. All levels of gamma irradiation groups produced an excellent survival response in the mutant candidate. The high diversity in morphological characteristics was reflected in the number of compound leaves, the width of compound leaves, and the number of leaves per pinnae, flowers, and pods. The dominant color of the lower leaves was 7.5 Green Yellow (5/6), and the middle leaves were 7.5 Green Yellow (5/6), while the dominant color of the upper leaves was 7.5 Green Yellow (6/8). The mutant candidate of D. virgatus exhibited the best characteristics, as determined by the concentration index, were those subjected to 200 Gray and 300 Gray irradiation. Fifteen superior mutant candidates were identified, namely GDV100.1, GDV100.2, GDV100.4, GDV100.5, GDV200.2, GDV200.3, GDV200.7, GDV200.9, GDV200.10, GDV300.3, GDV300.4, GDV300.5, GDV300.12, GDV300.13. and GDV 500.1. The three best mutant candidates (M1) were GDV100.2, GDV200.3, and GDV500.1. The three best mutant candidates (M1) were GDV100.2, GDV200.3, and GDV500.1.

Abstract

Pakchong elephant grass (PEG) is a super fodder with significant nutritional content and high production levels. The purpose of this research is to quantify the growth and yield of PEG through nitrogen fertilizer engineering with different dosages and repeated fertilization methods. A completely randomized design (CRD) was employed in the investigation, with 4 different levels of urea dosage (100; 200; 300; and 400 N kg/ha). And 10 replicates. ANOVA was used to evaluate the data, and Duncan's Multiple Range Test was then used to determine whether the treatments were substantially different (P<0.05). The findings demonstrated that the addition of nitrogen fertilizer at dosages of 200–400 N kg/ha was better compared to 100 N kg/ha at the end of maintenance (8 weeks after planting) for the quantity of leaves, leaf length, the height of plant, production of both fresh and dry biomass of PEG. There were no significant effect (P>0.05) in nitrogen fertilizer levels at the end of maintenance (8 weeks after planting) for leaf width, leaf chlorophyll content, stem sugar content, quantity of tillers, and the leaf-to-stem ratio of PEG. The research's conclusion indicates that adding nitrogen fertilizer up to 400 N kg/ha is generally safe and feasible for the growth and production of PEG. A nitrogen fertilizer dosage of 200 N kg/ha is optimal to meet PEG's growth and production needs.

Abstract

The lowland area of Indonesia has economic potential to develop as a major centre for dairy farming businesses. Still, there is a foremost matter: overheated irradiation immersed in damped air would increase the heat stress level. The present study was conducted to assess the heat stress tolerance level of lowland Indonesian Holstein cows, characterized by a dominant level of Black and White (B/W) pigmented skin coat. This study involved 34 heads of Holstein cows that were cared for in Eastern Jakarta. Breathing frequency (BF), rectum's warmth (RW), pulse rate (PL), white-skinned spot temperature (WSST), black-skinned spot temperature (BSST), average temperature rounded skin (ATRS), back region temperature (BRT), chest region temperature (CRT), upper-leg temperature (ULT), lower-leg temperature (LLT), skin's temperature (ST), body's temperature (BT), and heat tolerance coefficient (HTC) as variables were checked statistically with R 4.4.2 type software comprised correlation and independent t-test. Cows B/W classification performed with the imageJ 1.54g series program. Those analyses showed that most lowland Indonesian Holsteins were characterized by black-pigmented dominant cows (BDC). The pigmentation of both lateral sides of the body generated a significant correlation (p<0.05 and p<0.01) with several vital symptoms, including WSST, ATRS, ST, BT, and HTC, but only in the BDC Holstein class. The test of mean distinction between the two classes (BDC and WDC) produced statistically insignificant differences (p>0.05) in all measurable vital symptoms; all variables showed trends indicating that the BDC class had a greater response to heat stress. The BDC Holstein type selection base had high expectations of elevating the HTC score in Indonesian lowland cows, as the closing decision.
