Research note: Effect of diet based corn fodder on semen quality of Ettawah grade bucks
Get PDFThis study evaluated the impact of corn fodder supplementation on the semen quality of Ettawah grade bucks. The bucks used in this study were three Etawah crossbred goats with ages 2-6 years. Feed treatment this study, T0: Concentrate without corn fodder, T1: Concentrate with corn fodder. The parameters observed were: Macroscopic parameters included volume, colour, consistency, and pH; and microscopic parameters included mass motility, motility, viability, abnormality, concentration. Results revealed that the addition of corn feed to the diet of bucks did not have a significant effect on sperm quality macroscopically, but it did improve microscopic indicators such as motility and viability. However, there was an increase in abnormalities and a decrease in sperm concentration, which raises concerns about the overall reproductive potential of bucks. Therefore, further research is needed to determine the optimal corn feed mixture in the diet and to investigate mitigation strategies for the negative effects on sperm quality
Effect of gum arabic addition on physicochemical characteristics of goat milk yoghurt with mango puree
Get PDF Goat's milk has lower allergenic properties and higher digestibility compared to cow's milk. However, it possesses a distinct goaty aroma and a weak texture that is prone to syneresis. Efforts to improve the texture of goat milk yoghurt were made by adding gum arabic enriched with mango puree. This study aimed to determine the effect of gum arabic addition on the viscosity, syneresis, pH value, and water contact angle of yoghurt. The experimental design used was a completely randomized design (CRD) with four levels of gum arabic (0%, 0.25%, 0.5%, and 0.75%). The data were analyzed using Analysis of Variance (ANOVA) at a 0.05 significance level, followed by Duncan's Multiple Range Test (DMRT). The results showed that the addition of gum arabic treatment had a significant effect on viscosity and syneresis and tended to reduce the pH value of yoghurt. The addition of gum arabic as much as 0.75% was identified as the best treatment, yielding a viscosity of 11.8 ± 0.84 dPas, a syneresis value of 15.98 ± 1.18%, and a pH of 4.13 ± 0.034. Water contact angle measurement results showed a tendency to increase the contact angle due to the addition of gum arabic.
Effects of fermented jamu on nutrient intake, milk production and udder health of dairy cows in smallholder farms
Get PDFJamu is a word in the Javanese language, meaning traditional medicine made from plants. It is commonly used for humans but also has benefits for animals. The main objective of this study was to determine the effect of jamu containing Calliandra calothyrsus leaves, Carica papaya leaves, Curcuma longa Linn, fermented soybean (tempe) and molasses on nutrient intake, milk production and udder health. Jamu was given orally to the lactating dairy cow at a dose of 10 mL twice daily before milking. The study was conducted in Getasan, Central Java used 16 lactating Friesian Holstein crossbred cows with an average body weight of 455.12±40.32 kg and milk production of 10.65±1.95 l/day. This experiment used a 2 x 2 crossover design. The cows were grouped into control (fed basal ration) and treatment (fed basal ration and jamu oral). The parameters observed were in-vitro digestibility, nutrient intake, milk production, milk composition and somatic cell count. The results showed that jamu administration had no significant effect on in-vitro digestibility, nutrient intake, milk production and composition but significantly (P<0.05) reduced the somatic cell count from 8.6 x105to 5.1 x105. The conclusion of the study was that jamu did not increase nutrient intake and milk production but could improve the udder health of dairy cows
Nutritional composition and thai consumer buying behavior of dead fertilized and incubated chicken eggs in the northeastern region of Thailand
Get PDFThis study examined consumer purchasing behavior toward dead fertilized and incubated chicken eggs (balut) in the upper northeastern region of Thailand, alongside their nutritional composition. Two trials were conducted. In Trial 1, data were collected from 400 respondents through a structured questionnaire to assess factors influencing purchase decisions. Results indicated a stronger preference for dead fertilized egg over incubated eggs. Participants favored consuming the yolk and white separately in dead fertilized eggs, citing superior taste, texture, and overalleating experience. Trial 2 analyzed the nutrient profiles of different egg types. Whole boiled chicken eggs contained the highest moisture content (P<0.05), dead fertilized eggs showed the greatest fat levels (P<0.05), and incubated eggs exhibited the highest protein and vitamin A content (P<0.05). Overall, odor was identified as the primary factor influencing consumer choice, with dead fertilized eggs generally preferred. Nutritionally, dead fertilized eggs offer notable fatcontent, while incubated eggs provide high protein and vitamin A, highlighting their for value-added egg product develpoment
Effect of various incubation time on proximate component of fermentation process of ammoniated palm dregs using Aspergillus niger starter
Get PDFThis study aimed to examine the effect of various fermentation times on proximate component of the fermentation process of ammoniated palm dregs using Aspergillus niger starter; conducted at Feed Technology Laboratory, and Feed Science Laboratory, Faculty of Animal and Agricultural Sciences, Universitas Diponegoro, Semarang. This study used ammoniated palm dregs (ammonia content was 5% DM substrate) and A. niger starter. This study employed a completely randomized design (CRD) with three treatments and five replications. The treatments applied were different fermentation times, including: T0 = 0 days fermentation time, T1 = 3 days fermentation time, T2 = 6 days fermentation time. Parameters observed were proximate component consisting of moisture, ash, crude protein (CP), ether extract (EE), crude fiber (CF), and nitrogen-free extract (NFE). Analysis of variance was used to examine the data, followed by Duncan's multiple range test at 95% significance level. Results showed that different fermentation times significantly affected (P<0.05) all proximate components. Longer fermentation times decreased moisture, EE, CF, and NFE content, while increasing ash and CP content. The 6-day fermentation treatment resulted in the lowest moisture (50.37%), EE (0.65%), and CF (22.98%) content, and the highest ash (1.68%) and CP (20.04%) content. In conclusion, increasing the fermentation time to 6 days improved the nutritional value and quality of palm dregs by increasing ash and CP content and decreasing moisture, EE, CF, and NFE content, making it a suitable ruminant feed
From field to feed: Evaluating herbs and horticultural by-products for agricultural characteristics and nutritional values in Bulukumba Regency, South Sulawesi
Get PDFThis study aimed to evaluate locally available agricultural by-products and herbs as alternative feed resources for ruminants. A total of 15 plant species, including horticultural by-products, conventional forages, and herbs, were initially assessed based on palatability, availability, bioactivity, and toxicity. Primary data were collected from local cattle farmers (n=50) in the district of Rilau Ale, Bulukumba regency and the field officers (n=5) of the department of horticulture from Bulukumba regency. The 15 initial plants were ranked on the basis of palatability, availability, potential as feed sources, history as herbal medicine and toxicity. From then, six candidates were selected: banana stem, rambutan peel, vegetable waste, rice bran, ginger, and turmeric were selected for further study. The analysis revealed the presence of terpenoids, phenolics, sugars, fatty acids, and nitrogenous compounds, which are known for their antioxidant, antimicrobial, and anti-inflammatory properties. Nutritional evaluations showed that vegetable waste had the highest crude protein (21.26%) and ginger had the highest total digestible nutrients (TDN) at 59.63%. Banana stem, although low in protein (1.73%), was rich in fiber and available year-round. Rambutan peel exhibited high tannin content (10.29%). Rice bran provided high ash and energy but contained undissolved ash, possibly reducing digestibility. The findings suggest that these materials, if processed and combined properly, offer potential as sustainable, cost-effective cattle feed. Additionally, their year-round availability and functional bioactive compounds may contribute to improved animal health and reduced environmental waste

This study used 200 unsexed day-old Ross 308 broiler chickens with fully randomized design, four treatments, five repetitions, and each comprising 10 birds. The treatments were as follows: T0, basal diet (control); T1, basal diet + 0.09% Japanese papaya leaf extract (EDPJ); T2, basal diet + 0.03% EEDPJ; T3, basal diet + 0.06% EEDPJ and T4, basal diet + 0.09% EEDPJ. Measurement the parameters using total lactic acid bacteria (LAB), total coliforms, small intestine pH, protein digestibility, lymphoid organ weight, heterophil/lymphocyte ratio (H/L), feed intake, daily weight gain, and feed conversion ratio (FCR). Data analysis used variance analysis and Duncan's Multiple Range Test at 5% significance. Supplementation with EEDPJ gives effect to led a significant improvement (P<0.05) in daily weight gain, feed conversion ratio (FCR), lactic acid bacteria population, coliform count, intestinal pH, relative weights of the bursa of Fabricius and spleen, heterophil/lymphocyte (H/L) ratio, and protein digestibility. In contrast, not significantly influenced (P>0.05) on daily feed intake and thymus weight. In inclusion, the addition of 0.06% EEDPJ in the diet enhanced protein digestibility, strengthened immune response, and improved the broiler chickens growth performance
Genetic polymorphisms of the Olfactomedin-like 3 gene and their association with cholesterol content, mineral composition, flavor and odor in Indonesian local sheep
Get PDFCholesterol content, minerals composition, flavor, and odor of sheep meat are always key factors for consumers to consider when choosing meat. The quality of sheep meat influences these aspects; otherwise, they are important to consumers when selecting good-quality beef. Thus, genetic improvement programs oriented toward increasing minerals and flavor in sheep meat and decreasing cholesterol are programs to increase consumer interest in these products. The Olfactomedin-like 3 (OLFML3) gene may serve as a genetic marker that influences cholesterol, mineral, flavor, and olfactory qualities in local sheep raised in Indonesia. This research was conducted to analyze this relationship and investigate variations in the OLFML3 gene, as well as the levels or contents of cholesterol, minerals composition, flavor, and odor in local sheep in Indonesia. This research analyzed longissimus dorsi muscle samples derived from 100 male sheep (10-12 months old). Genotyping of the OLFML3|MspI locus was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism, with association analyses conducted via the General Linear Model (GLM) methodology. Three distinct genotypes (CC, TT, and CT) were identified at the OLFML3 gene. Statistical evaluation revealed significant genotype effects on cholesterol concentration (P < 0.05), while statistically insignificant associations were detected for minerals, flavor, and odor (P > 0.05). The TT genotype in sheep was associated with significantly lower cholesterol concentrations than the CC and CT genotypes. The Olfactomedin-like 3 gene’s g.90317673 C>T SNP is a candidate genetic marker for low-cholesterol trait selection in Indonesian local sheep
Application of principal component factor analysis to identify key morphological traits in Garut ewes
Get PDFThis research utilized principal component factor analysis (PCA) to pinpoint significant morphological characteristics affecting the body structure of Garut ewes, a native Indonesian breed crucial for smallholder agriculture. The study analyzed data from 85 mature ewes, focusing on body weight (BW) and six linear measurements: body length (BL), chest depth (CD), chest girth (CG), rump width (RW), rump height (RH), and withers height (WH). Descriptive statistics indicated moderate variability in BW (mean = 47.84 kg, CV = 3.75%) and greater variation in skeletal traits (RH and WH CV > 20%). Correlation analysis revealed notable relationships between BW and BL (*r* = 0.294) and RW (*r* = 0.296), with RW and WH showing the strongest correlation (*r* = 0.429). PCA reduced dimensionality, with PC1 (35.7% variance) heavily loading on RW (0.776), WH (0.665), and RH (0.622), highlighting their significance in structural size. Regression models showed that PCA-derived components (PC1 and PC2) were more effective than individual traits, accounting for 52% of BW variability compared to just 9% for BL alone. These results emphasize the value of multivariate analysis in breeding programs, suggesting that composite indices (e.g., PC1 as a "size" factor) improve prediction accuracy over single-trait methods. Focusing on RW, WH, and RH in selection could boost productivity, while PC-based models provide practical BW estimation tools for resource-constrained farms. This study highlights the significance of integrated morphological analysis for the sustainable management of Garut sheep
Effect of methionine supplementation on the production of Friesian Holstein dairy cows
Get PDFA lack of certain amino acids, particularly methionine can lead to a number of issues in dairy cow output. This research aimed to evaluate the impact of methionine supplementation on the productivity of Friesian Holstein dairy cows during their lactation phase. The observational study was carried from January 2022 to December 2023 at a dairy farm located in West Java. A total of 82 Friesian Holstein dairy cows that had recently calved or were in the early stages of lactation, with a BCS from 3.25 to 3.75. The cows were housed in one barn. They were fed a total mixed ration (TMR) consisting of corn silage, alfalfa hay, and concentrate, which had a crude protein content of 16% and a total digestible nutrient (TDN) level of 67%. The treatments applied were T0 = Ration without methionine supplementation (control) and T1 = Ration with 25g/head/day methionine supplementation. The treatment was given during lactation until the cows gave birth again in the next period. The parameters observed included average feed intake (AFI), milk yield, milk quality factors such as fat, protein, lactose and fat-to-protein ratio. The analysis used was descriptive analysis with the Independent Sample T-test using SPSS 25. The results showed that methionine supplementation (T1) had a significant effect (P<0.05) for increasing on average feed intake (AFI) and milk quality such as fat, protein, lactose and fat protein ratio and did not have an impact on milk yield
