The Effect of Shading Conditions and Mowing Frequency on Plant Diversity, Productivity, Soil Nitrogen and Mineral, and Mineral Profiles of Dominant Forages of Grazing Pasture

2025-02-17T03:19:05+00:00

The research aimed to study the effect of three different paddock management systems on nitrogen and mineral status of soil, plant diversity, and biomass production and to discuss the potential nutritional effects of macro mineral profiles of dominant forages on grazing cattle. The research was conducted in a Completely Randomized Design (CRD) 3x4, consisting of 3 paddocks as treatments and four plots as replicates. The pasture was divided into three paddocks based on shading conditions and mowing frequency: P1: unshaded by trees and rarely mowed; P2: unshaded but regularly mowed; and P3: shaded by numerous trees and never mowed. Each paddock was divided into four plots based on plant density, with plant and soil samples collected at 17 sampling points per plot. Measured parameters included botanical composition, dominant species, dry matter, and macro mineral concentration of calcium, sodium, phosphorus, sulfur, magnesium, and potassium in the soils and dominant forages. The grazing pasture was inhabited by around 110 native plant species, dominated by Imperata cylindrica (19.6%), Axonopus compressus (16.8%), Mimosa pudica (12.1%), Digitaria sanguinalis (10%), Elephantopus mollis (9.0%), and Euphorbia hirta (8.5%). Biomass production ranged from 110–135 kg/ha/day, with a carrying capacity of 2.5–3.0 AU/ha (significant at p<0.05). Different mowing frequency and shading conditions influenced soil nutrient concentrations, forage diversity, and productivity. Considering requirements for growing cattle, the dominant species had a favorable content in Mg, K, and S but was deficient in P, Na, and Ca. In conclusion, the grazing pasture was populated by diverse native forage plants, and the dominant species were poor in several essential minerals of P, Na, and Ca, which are most likely to limit cattle productivity.

Physiological and Feeding Behavior Responses of Swamp Buffalo (Bubalus bubalis) Under Different Grazing Distances in a Silvopastoral System

2025-02-17T04:02:41+00:00

Mud buffalo (Bubalus bubalis) is one of Indonesia's livestock commodities with a high potential to be developed. However, its utilization has not been optimized to the fullest. This study aims to evaluate the effectiveness of the silvopasture system in improving mud buffalo welfare based on physiological responses and feeding behavior. This study was conducted in Peguyangan Village, Bantarbolang Subdistrict, Central Java Province. Ninety-one buffaloes were observed using a purposive sampling technique grouped by sex and age. Variables observed included grazing distance, environmental temperature and humidity, physiological responses, Heat Tolerance Coefficient (HTC) values, and feeding behavior. T-test analyzed data. The results showed the highest body temperature (38.08 ˚C) in adult male buffaloes with a grazing distance of 5 km. Buffaloes grazed within an 8 km radius had higher respiration rate (42.48±2.67 bpm) and travel speed (1.14 km/h), with shorter feeding duration (03:18 minute) compared to a 5 km distance (03:57 minute). HTC analysis showed low heat tolerance in both regions. Feeding behavior was observed more frequently in female buffaloes. Silvopasture systems integrated with teak forests can provide adequate nutrition, with grazing distance influencing physiological adaptations.

2025-02-17T04:22:29+00:00

This study aimed to determine the effect of vitamin E supplementation on tris-egg yolk diluent using different quality fresh semen. The research material was ejaculated from six Simmental bulls and then classified into standard quality (SQ) and low quality (LQ) according to progressive motility. The research method was experimental with a randomized factorial design (2X5), with the group by fresh semen with 3 replications. The first factor was the quality of fresh semen, while the second factor was the level of vitamin E addition (B0: 0mg/ml; B1: 0.5 mg/ml; B2: 1 mg/ml; B3: 1.5 mg/ml; and B4: 2 mg/ml). After thawing, the observation parameters were motility, viability, abnormality, plasma membrane integrity, and MDA levels. The result shows that the quality of fresh semen has a very significant effect (p<0.01) on the motility of frozen semen (66.28±8.66%) and a significant impact (p<0.05) on the plasma membrane integrity (91.31±2.87%). The use of vitamin E at 1 mg/ml showed the best results on motility (66.11±7.64%), viability (70.19±12.13), abnormality (12.00±3.13), and MDA (2.11±0.77). This study concludes that adding vitamin E to the diluent can increase motility, viability, and plasma membrane integrity while reducing abnormality and MDA levels. Low-quality fresh semen can be processed into frozen semen after adding vitamin E. The best level of vitamin E addition is 1 mg/ml.

A study to determine the effect of vitamin A and magnesium supplementation on Dry Matter Digestibility (DMD) and Organic Matter Digestibility (OMD) in lamb. The research was conducted experimentally using a Randomized Completely Block Design (RCBD) using 18 rams local aged 7 - 8 months with an average initial body weight of 20 kg ± 2.38 kg. The feed was given at 4% Dry Matter (DM) of body weight with a ratio of ammoniated rice straw and concentrate of 25%:75%. The treatments tested were T0 (control), T1 (25% ammoniated rice straw, 75% concentrate, plus 2000 IU of vitamin A), and T2 (25% ammoniated rice straw, 75% concentrate, plus 2000 IU of vitamin A, plus 1 gram of magnesium). The results of the variance of the analysis showed that the treatment of vitamin A and Magnesium administration had a real effect (p<0.05) on the digestibility of organic matter, while other variables were not accurate. The average digestibility of organic matter was T0 at 91.49%, T1 at 91.19%, and T2 at 92.24%. T2 was the treatment with the highest digestibility, with a difference of 2.75% from the control treatment. After the Randomized Completely Block Design (RCBD) and Variance of Analysis test, the next test used Honestly Significant Difference (HSD). Vitamin A and Magnesium supplementation affected the digestibility of organic matter by 2.75% higher than the control treatment.

This study aims to determine the diversity and correlation of egg production performance in Sikumbang Jonti ducks as a basis for making selection decisions. The materials used were 47 female Sikumbang Jonti ducks. In the production phase, Sikumbang Jonti ducks were intensively reared in individual battery cages for 24 weeks. The observed variables were body weight (g), age at first laying (days), egg production (eggs), and egg weight (g). Data on body weight, age at first laying, total egg production, and egg weight were analyzed descriptively by calculating the mean value, standard deviation, coefficient of variation, minimum value, and maximum value. Furthermore, data on body weight, age at first laying, egg production, and egg weight were also analyzed for correlation to see the direction and relationship between variables. The results of this study were that Sikumbang Jonti ducks have an average body weight of 1299g, age at first egg laying of 170.19 days, average total egg production of 36.62 eggs, and average egg weight of 59.06g. The diversity of body weight, age at first egg laying, and egg weight of Sikumbang Jonti ducks are moderate, while the diversity of egg production is high. The diversity of body weight, age at first laying, and egg weight of Sikumbang Jonti ducks are included in moderate diversity. In contrast, the diversity of egg production is included in high diversity. Based on the correlation of body weight, age at first laying, egg production, and egg weight of Sikumbang Jonti ducks, age at first laying is the selection variable that can be used as a good predictor of egg production performance. In conclusion, the study results show that a longer age of first laying can be used as a selection variable to increase the production and egg weight of Sikumbang Jonti ducks.
