Abstract

This study aimed to analyze the effect of using wheat flour, breadfruit flour, and a combination of both, as well as the addition of carrots, on the quality of chicken nuggets. This study was conducted in two experimental stages using a Completely Randomized Design (CRD). Stage I used a 3x4 factorial RAL pattern with 3 repetitions. Factor A (Type of flour) consisted of wheat flour (X), a mixture of wheat flour and breadfruit flour (Y), and breadfruit flour (Z). Factor B (flour level) included 7.5%; 15%; 22.5%; and 30%. Stage II used a single-factor RAL with four treatments of carrot addition levels (P): 7.5%; 15%; 22.5%; and 30%, each repeated three times. The research parameters included cooking loss, meat shear force, and water holding capacity (stage I) as well as cooking loss, meat shear force, water holding capacity, dietary fiber, and β-carotene (stage II). Phase I research showed that the type and level of flour had a very significant effect (P<0.05) on water holding capacity and meat shear force. The use of 15% breadfruit flour and 30% carrot gave the best results in cooking loss (5.00%), β-carotene (245.13 µg/100g), and dietary fiber (5.82%). Keywords: Nuggets, breadfruit flour, carrots, physicochemical properties

Abstract

One of the weaknesses of the livestock sector management in Indonesia, particularly in Sinjai Regency, is the lack of population data. The available data so far mostly consists of general beef cattle population data without clear population structure details. To understand the development of the beef cattle population, a forecasting approach based on various beef cattle population data in Sinjai Regency is necessary. This study aims to analyze the structure and dynamics of the beef cattle population and calculate the predicted population development of beef cattle in Sinjai Regency. This research uses a case study method with purposive location selection. The beef cattle population dynamics data were processed using the time series forecasting method, specifically exponential smoothing with α = 0.9, based on annual data over 10 years from 2015 to 2024. The results show that if the data behavior remains the same as the actual data from the past 10 years, the overall structure of the beef cattle population in Sinjai Regency consists of fewer male cattle compared to female cattle. The forecasted beef cattle population in Sinjai Regency for 2025–2034 varies and tends to increase year by year, except for a decline in population in 2033 due to technical constraints in the development of beef cattle by the community in the field. Keywords: Forecasting, Population, Beef Cattle, Sinjai Regency.

Abstract

Semen quality is influenced by the frequency of ejaculation, which is significant to semen characteristics. The purpose of this study was to analyze the effect of ejaculation frequency on the quality of fresh Bali cattle semen, which includes volume, motility, and concentration of spermatozoa at the AI Center Pucak Maros. This study used secondary data from production records (recording) derived from 5 Bali cattle males, with a frequency of ejaculation of 2 times. The results showed that the frequency of ejaculation was statistically significantly different (P<0.05) in semen volume in males 11442 and 11434; the percentage of motility was significantly different (P<0.05) in male 11539; and the concentration of spermatozoa was significantly different (P<0.05) in males 11442, 11434, and 11539. The correlation coefficients for the three quality parameters showed negative correlations between semen volume and motility (R=-0.531) and concentration (R=-0.414), whereas motility and concentration were positively correlated (R=0.740). In conclusion, the second ejaculation has an impact on increasing semen volume but will reduce the percentage of motility and concentration of spermatozoa. Keywords: ejaculation frequency, Balinese cattle, volume, motility, concentration

Abstract

The objective of this study was to identify botanical composition, diversity, and forage production. This study was conducted in Kadundung village and Boneposi village, Latimojong subdistrict, Luwu regency. This study is classified as descriptive research using qualitative and quantitative approaches, through observational surveys and documentation studies. The parameters in this study include botani, biodiversitas, and forage production. The results showed that the average percentage of botanical composition in Kadundung Village was: grasses 48.29%, legumes 14.59%, and other plants 37.12%. Forage production yielded a fresh weight of 4.18 tons/ha/year, and the biodiversity richness index (4.20), diversity index (0.84), and evenness index (0.28) were measured, with a carrying capacity of 0.17 AU/ha/year. Meanwhile, the average percentage of botanical composition in Boneposi Village was: grasses 45.32%, legumes 16.52%, and other plants 38.16%. Forage production yielded a fresh weight of 4.36 tons/hectare/year, and the biodiversity richness index (2.90), diversity index (0.82), and evenness index (0.24). Therefore, botanical composition, vegetation diversity, and forage production are still. These findings underscore the importance of an integrated approach to grassland management that accounts for seasonal patterns to maintain ecological balance and sustain year-round grassland productivity.

Abstract

Pine forest undergrowth in tropical regions often remains underutilized despite its potential to alleviate forage deficits for ruminant livestock. This study explored whether moderate NPK fertilization could enhance the growth and quality of dwarf elephant grass (Pennisetum purpureum cv. Mott). A Completely Randomized Design was employed to test four fertilization levels (0 (T0), 3 g (T1), 6 g (T2), and 9 g (T3) of NPK per cutting) in a pine canopy environment, with each treatment replicated three times. Key data included the stem-to-leaf ratio, Neutral Detergent Fiber (NDF), and Acid Detergent Fiber (ADF). Soil nutrient status and microclimate (light intensity, temperature) were also monitored. Statistical analysis utilized ANOVA followed by multiple range tests. The results show that moderate fertilization rates (3 g and 6 g) increased leaf growth, yielding significantly lower stem-to-leaf ratios than the control and the highest fertilizer treatment (9 g). Moreover, NDF and ADF values rose with escalating fertilizer rates; at 9 g, fiber content was notably elevated, suggesting a decline in forage digestibility. Moderate NPK fertilization effectively leverages pine forest undergrowth to produce high-quality forage by enhancing leaf growth without excessively increasing fiber content. Keywords:  dwarf elephant grass, fertilizer, forage quality, pine forest

Abstract

ABSTRACT This study aimed to evaluate the effect of mixed cropping of maize (Zea mays) with pinto peanut (Arachis pintoi) on the nutrient content of maize grain and straw. A randomized group design (RGD) was employed with five treatments and three replications. The treatments consisted of P0 (100% maize), P1 (80% maize + 20% legume), P2 (50% maize + 50% legume), P3 (20% maize + 80% legume), and P4 (100% legume). The parameters observed included crude protein, neutral detergent fiber (NDF), and acid detergent fiber (ADF) content of maize grain and straw. Analysis of variance revealed that mixed cropping had no significant effect (P>0.05) on the nutritional composition of both maize grain and straw. In conclusion, intercropping maize with Arachis pintoi does not significantly influence the nutritional quality of maize under the conditions of this study. Keywords: Arachis pintoi, maize feed, mixed cropping, production

Abstract

Somatic cell nuclear transfer (SCNT) in pigs remains inefficient, mainly due to incomplete nuclear reprogramming of donor cells. Induced pluripotent stem (iPS) cells have been proposed as promising nuclear donors, but their developmental competence in porcine SCNT is unclear. This study compared the in vitro developmental ability of embryos reconstructed with porcine embryonic fibroblasts (PEFs) or porcine iPS (piPS) cells. Developmental rates, total and epiblast cell numbers were assessed in SCNT, in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and parthenogenetic activation (PA) embryos. The effect of oocyte activation status on piPS-derived SCNT embryos was also examined. Expression of well-known pluripotency transcription factor genes OCT4, SOX2, NANOG, c-MYC, and KLF4 were quantified by quantitative Reverse Transcription Polymerase Chain Reaction (qRT-PCR). Results showed cleavage and blastocyst formation rates of piPS-derived embryos (55.0% and 14.6%) were comparable to PEF-derived SCNT, IVF, and ICSI, while PA embryos showed significantly higher rates (67.8% and 44.5%). Non-activated oocytes yielded higher development than activated ones. Blastocyst cell numbers were similar across groups; however, SCNT embryos contained fewer epiblast cells than IVF and PA. qRT-PCR showed markedly reduced OCT4, comparable SOX2, NANOG, and c-MYC, and higher KLF4 in NT and PA embryos than IVF. The results conclude that piPS cells can serve as nuclear donors but do not improve cloning efficiency compared with fibroblasts. Aberrant lineage allocation and dysregulated gene expression suggest incomplete reprogramming, highlighting the need for improved piPS quality. Key words: induced pluripotent stem cells (iPSCs), pig, nuclear transfer
