Abstract

Caramel candy or toffee is a confectionery product made from basic sugar, glucose syrup, milk, fat, and salt ingredients. Sugar plays a role in the formation of brown color and caramelization, while the addition of red ginger acts as a flavor enhancer for caramel candy. The reaction results in the production of melanoid and antioxidant compounds. It also affects the taste, texture, aroma, and appeal of caramel candy. This research aimed to analyze the effects of the use and interaction of sugar and red ginger on antioxidants, organoleptic tests, and color L*, as well as chemical (reducing sugar and water content) changes in caramel candy products. This research design used a completely randomized design with a factorial pattern, with factor A adding sugar (0, 5, 10, 15) %; factor B adding red ginger juice (0, 2, 4, 6) %. This research shows that sugar and ginger juice can increase the A* color value, ginger taste, caramel taste, color, ginger, and caramel aroma. Meanwhile, increasing sugar and ginger juice can reduce the L* color value, antioxidant activity, and water content. Adding 15% sugar and 4% red ginger juice is the best for making red ginger juice. Keywords: Milk caramel candy, red ginger juice, sugar, physicochemical quality

Abstract

In ruminant livestock, it is very important to pay attention to the adequacy of micro minerals and vitamins, considering that minerals and vitamins are absolute and must be present in the feed so that the health and productivity of the livestock is not disturbed. To produce quality semen, vitamin E, selenium and zinc are needed. These micronutrients play a role in the spermatogenesis process which will have an impact on the quality of spermatozoa produced by male livestock. The aim of this study was to determine the effect of supplementation of micronutrient on sperm movement pattern of Bali bull. This study was used two Bali bull aged 4-5 years with a body weight of 300-350 kg. The study was divided into two periods of treatments and each period was carried out for three weeks. In the first period (control), experimental Bali bull was fed natural grasses and concentrate (1% of body weight). Furthermore, in the second period (treatment period), the feed was similar as the first period with the addition of a mixture of minerals (Zn and Se) and vitamin E. The volume, color, pH, viscosity and movement pattern of the bull's sperm were recorded. Likewise, sperm concentration, motility, viability and abnormality were measured. Fresh semen was diluted with Andromed® accordingly before subsequent processing. Data were analyzed using paired student t-test. The results of the study showed that the macroscopic quality of fresh semen of Bali bull improved after supplementation of micronutrient. The movement pattern of spermatozoa after administration of micronutrient supplements did not have a significant effect (P>0.05). It can be concluded that micronutrient supplementation in Bali bulls can improve macroscopic evaluation, abnormality, viability, concentration and maintained spermatozoa movement patterns. Keywords: Bali bull, spermatozoa, micronutrient, semen quality, and movement

Abstract

This study investigated the expression patterns of HSP90 and HSP70 genes, which encode heat shock proteins, using 45 genomic DNA samples isolated from West African Dwarf (WAD) goats in Nigeria. The polymorphism information content (PIC) of each marker was evaluated to determine its level of informativeness. DNA samples were collected from apparently healthy WAD goats in Osun, Oyo, and Kwara States under field heat-stress conditions, with ambient temperature and relative humidity recorded at the time of sampling. Polymerase chain reaction (PCR) amplification was performed using primers specific for each heat shock protein gene, and the PCR products were analyzed by polyacrylamide gel electrophoresis on an ABI 3730 DNA Sequencer. Allelic variation was assessed using Microsatellite Analyzer software to generate allele frequencies. The results revealed alleles A and C as the predominant alleles for markers SSR1 (HSP90) and SSR2 (HSP70), respectively. The effective number of alleles and expected heterozygosity were higher for SSR2 (He = 0.40) than for SSR1 (He = 0.36). PIC values ranged from 0.55 (HSP90) to 0.59 (HSP70), indicating that both markers were informative (PIC ≥ 0.50). This study provides the first molecular characterization of HSP90 and HSP70 gene polymorphisms in WAD goats under tropical heat-stress conditions, suggesting their potential as reliable genetic biomarkers for thermotolerance selection and future breeding programs aimed at improving heat resilience in tropical livestock. Keywords: Heat shock proteins; HSP90; HSP70; thermotolerance; West African Dwarf Goat

Abstract

This study aimed to identify potential weed species suitable as raw materials for fermentation technology in producing nutrient-rich organic fertilizers, thereby linking sustainable agricultural innovation with Islamic environmental ethics. A Completely Randomized Design (CRD) was employed with four treatments based on the volume of fermented weed-based fertilizer (0, 30, 40, and 50 mL) and three replications, resulting in a total of 36 experimental units. Observed parameters included plant height, leaf area, and chlorophyll content, while forage quality was analyzed through neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) composition. Results showed that weed fermentation had no significant effect on plant growth (P > 0.05) but significantly improved forage quality (P < 0.01) across fertilizer doses. Fermented weed-based fertilizer thus proved effective for enhancing the nutrient quality of green fodder sustainably. This research introduces a novel integration of weed fermentation technology and Islamic ethical principles, providing an innovative model for eco-friendly and faith-aligned agricultural practices. Keywords: Weed fermentation; organic fertilizer; forage quality; sustainable agriculture; Islamic agricultural ethics

Abstract

The hematological profile and blood metabolite status are indicators of the physiological condition of livestock. This study aimed to determine the correlation between blood metabolite profiles (blood glucose and cholesterol) and sperm quality (motility and abnormality) in fresh Bali bull semen. Blood collection and semen sampling were conducted twice a week for 5 weeks. The collected blood and fresh semen were evaluated from two treatments: before and after the addition of micronutrients (including Zn, Se, and Vitamin E) in the feed. The parameters observed in this study were blood metabolite profiles (blood glucose and cholesterol levels) and sperm quality (percentage (%) motility and % abnormality of spermatozoa) before and after the addition of micronutrients. The data obtained were analyzed using simple linear regression and correlation tests. The results of this study showed that both treatments had a correlation between blood metabolite profiles and sperm quality in fresh Bali bull semen. Blood glucose levels correlated with sperm motility in fresh Bali bull semen, and good sperm motility values were obtained in all treatments before and after micronutrient administration in the feed. Cholesterol levels correlated with sperm abnormalities in fresh Bali bull semen, and all treatments before and after micronutrient addition in the feed showed abnormality values above the standard value. The blood metabolite profile (glucose and cholesterol) correlates with spermatozoa quality (motility and abnormalities) in fresh semen from Bali bull, where the addition of micronutrients in feed can increase spermatozoa motility but is not effective in suppressing the decrease in spermatozoa abnormalities. Keywords: Blood metabolite, blood sugar, cholesterol, spermatozoa quality

Abstract

The lactation phase of dairy cows is very important in determining the quality of milk produced. The lactation phase is divided into three phases: early, mid, and late lactation. The objective of this study was to determine the milk quality and percentage of curd and whey of Holstein Friesian dairy cows at different lactation phases. This study was conducted using a completely randomized design (CRD) with 3 treatments and 5 replicates of each treatment. The treatments in this study were P1 = early lactation, P2 = middle lactation, and P3 = late lactation. The research data were processed through the SPSS application using the ANOVA test, and if there was a difference between treatments, it would be further tested using the Duncan test. The lactation phase significantly affected (P < 0.05) the fat content and curd production of Holstein Friesian cow milk, but did not significantly affect the protein content, pH, specific gravity (SG), and viscosity of Holstein Friesian cow milk. The lactation phase has a significant impact on the milk quality and percentage of curd and whey in Holstein Friesian dairy cows. It has been observed that during the late lactation phase, the milk quality tends to be higher, which is a noteworthy finding for dairy farmers. Keywords: Phase of lactation, physical quality, chemical quality, curd, and whey

Abstract

The study was conducted to investigate the effect of prebiotic, probiotic, and synbiotic supplementation through drinking water on broiler performance and small intestine morphology. A total of 100 day-old broiler chicks (Ross) were randomly allocated into 4 treatments with 5 replicates, with 5 broilers in each experimental unit for 35 days. The drinking water treatments were P0: Water (Control); P1: Water + Prebiotic (5 g/L); P2: Water + Probiotic (3 g/L); P3: Water + Synbiotic (Probiotic 3 g/L + prebiotic 5 g/L). Commercial feed consisting of the three rearing phases was used during the study, and drinking water was provided ad libitum. Parameters measured were water and feed consumption, body weight gain, feed conversion, performance index, small intestine morphometry, which is measured by the length/weight ratio, and Histo-morphometry of the small intestine of individual segments, duodenum, jejunum, and ileum at the end of the experiment on 3 chicken samples (lightest, medium, heavy) from each treatment. The results showed that prebiotic, probiotic, and synbiotic supplementation through drinking water significantly (P<0.05) affected drinking water and feed consumption, body weight gain, feed conversion, length/weight ratio, and histo-morphology of the small intestine. Overall, it can be concluded that synbiotic supplementation demonstrated a synergistic effect between prebiotics and probiotics, outperforming prebiotic and probiotic supplementation separately in terms of performance, small intestine ratio, and small intestine histomorphology. Synbiotics also significantly showed a trend towards feed use efficiency, as seen in feed conversion. Keywords: Broiler Chicken, Natural Growth Promotor, Performance Index, Intestinal Gut Ratio, and Intestinal Histomorphometry
