Objective: Diabetes mellitus (DM) is a prevalent endocrine condition found in cats. Recent research has identified a connection between a higher risk of diabetes in cats and genetic factors. This genetic susceptibility to type 2 diabetes is associated with genes that control insulin secretion and function, as well as those that impact factors like obesity. The purpose of the study was to determine the prevalence of the melanocortin 4 receptor (MC4R) gene missense mutation among cats and to investigate the relationship between body condition score (BCS) and the occurrence of diabetes in felines. Materials and Methods: Genotype analysis was done for 45 samples. The research results were obtained with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The 1,200-bp PCR product was cut with BstOI restriction enzyme. Results: Upon analyzing the data, it was found that 37.8% (n = 17) of the subjects carried the MC4R gene mutation. Across the entire population of cats studied, the C allele associated with the mutation was most prevalent in the group of cats with DM (frequency of 0.3) and least common among the clinically healthy cats (frequency of 0.2). Conclusion: After analysis of the study results, a statistically significant difference was observed between cats with DM and clinically healthy cats in the comparison of their BCS (p < 0.05). The association of the MC4R gene polymorphism with overweight and the development of diabetes has been identified. [J Adv Vet Anim Res 2024; 11(3.000): 738-745]

Objectives: This study aimed to investigate the physical properties of Indonesian local sheep skin collagen extracted by acid and enzymatic methods. Materials and Methods: Collagen was isolated from Pure Breed Garut Sheep (Ovis aries sp.) skin, 1.5 years old. The skins were obtained from a local slaughterhouse in Cirebon, Indonesia. The solvents used were CH3COOH and three different enzymes: neutrase, alcalase, and bromelain. Results: The highest yields of extracted collagen were bromelain-soluble collagen (BSC), which reached 37.07%. The range of Ph values for all samples started from 4.01 to 4.76. The viscosity values (cP) of acid-soluble collagen (ASC), neutrase-soluble collagen (NSC), alcalase-soluble collagen (LSC), and BSC were 3.42, 3.90, 3.45, and 3.12, respectively. Regarding SDS-PAGE analyses, Garut sheepskin collagen is categorized as collagen type I, which has a molecular weight of about 140.99 to 148.74 kDa for α1 and around 110 to 111.86 kDa for α2. The results of FTIR and DSC analyses for all samples show the same motif with commercial collagen motifs based on the literature. Conclusion: Garut sheep skin has the potential to be an alternative raw material source for producing collagen. Collagen extracted using a combination of CH3COOH and bromelain enzyme showed the most desirable results in almost every characteristic. [J Adv Vet Anim Res 2024; 11(3.000): 722-728]

Objective: This study aimed to assess the welfare conditions of broiler chickens in the live bird markets (LBMs) in Bangladesh. Materials and Methods: A total of fifty broiler outlets were studied in 10 LBMs of Chattogram, Bangladesh. A total of 10 chickens were observed to check the welfare issues during slaughter from each outlet (N = 500). The data were collected using a structured questionnaire method through interviews of the vendors and observation of the lairage and slaughter practice. Results: The study revealed that the stocking density was significantly higher in cage-type lairage than in floor-type (p < 0.05). The feeding and drinking areas for the chickens were significantly but negatively correlated to the stocking density. The duration between unloading of broiler chickens at LBMs and feeding or drinking could exceed 5 hours in 22% of outlets. The mortality was significantly higher in the bigger outlets than the smaller outlets (p < 0.05). During pre-slaughter han¬dling, the one-wing grasping method was practiced more in the bigger outlets (p < 0.05) whereas the feet grasping method was used more in the smaller outlets (p < 0.05). Moreover, the knives used to slaughter the chickens were not sharpened daily in 76% of outlets. Conclusion: This study indicated that the broiler chickens in the LBMs of Chattogram had to face many stress episodes at different stages at their penultimate moments—from lairage to slaugh¬ter—which led to poor welfare conditions and exacerbated the suffering of chickens.

Objective: This study aimed to develop a mobile application (app) specifically designed for enhancing farm management and performance assessment in fattening beef cattle. Materials and Methods: The development process followed a user-centered design approach, which involved focus group discussions and key informant interviews with 20 participants to design content and features. The app was developed for both mobile and web platforms. After the prototype and launch of the app, the system usability scale (SUS) and user satisfaction were assessed. Results: The assessment findings identify the specific expected functions in the app, with the farm accounting records function being the most desired feature among users, followed by production analysis, production records, and resource inventory. The mean SUS score was calculated to be 75.17, indicating a qualitative assessment of "Good." The assessment of user satisfaction indicated that the mean satisfaction score for all participants was 4.26, suggesting a high level of satisfaction and a favorable perception of the app. Conclusion: This app provides an alternative way to record farm activity, suggest feed and feeding schedules, and provide financial management tools designed explicitly for small-scale beef cattle farmers.

Objective: This study was conducted to investigate the variants of the growth hormone receptor (GHR), growth hormone-releasing hormone (GHRH), pituitary-specific transcription factor-1 (PIT1), and signal transducer and activator of transcription 5A (STAT5) genes and their effect on growth performance and dressing percentage (DP) parameters. Materials and Methods: A total of 401 DNA samples from Sumba Ongole (SO) cattle were utilized for the polymerase chain reaction-restriction fragment length polymorphism method, of which 200 samples were used for the study of DP association and 74 samples were used to investigate growth performance. The SO cattle growth performance includes the following: birth weight, weaning weight at 205 days of age, weaning average daily gain (ADG), yearling weight at 365 days of age, and post-weaning ADG. Results: The GHR, GHRH, PIT1, and STAT5A genes showed polymorphism. The highest polymorphism information content value was shown in the STAT5A gene. The highest DP value was found in the SO cattle population with the CC genotype (STAT5A), and the lowest DP value was found in the SO cattle population with the GG genotype (GHR). The GHR and STAT5A genotypes were highly associated (p < 0.05) with the DP parameter. Based on locus combination analysis, the highest DP value was found in the SO cattle population with AG|CC genotype (GHR|STAT5A) (57.85%), AG|BB|CC genotype (GHR|GHRH|STAT5A) (57.85%), and AA|BB|BB|CC genotype 18 (GHR|GHRH|PIT1|STAT5A) (56.02%). Conclusion: All investigated genes in this study were polymorphic but were not associated with several growth parameters. The GHR and STAT5A genes can be proposed as genetic markers for the high DP trait in SO cattle in Indonesia, especially the AA genotype (GHR) and CC genotype (STAT5A).

Objectives: This study aimed to analyze the effects of the use of binders on the physical quality and digestibility of Alabio ducks (Anas platyrinchos Borneo). Materials and Methods: Pellet binders used tapioca meal (TM) (Manihot utilissima), sago meal (SM) (Metroxylon sagu Rottb.), and sweet potato meal (SPM) (Ipomoea batatas) pelleted feed. Laying Alabio ducks, around 120 birds, aged 20 weeks with an average body weight of 1,426 ± 113.5 gm, were used. A fully randomized design with 4 treatments and 15 repeats was used in this study. The variables measured include the physical quality and digestibility of pellet feed. Data analysis used a Fisher test. For the distinction between treatments, the Duncan multiple-range test was conducted. Results: The finding showed that the plant-based pellet binder had a natural effect on physical properties, including pellet durability index, moisture content, threshold power, stack density, and stack compacted density. The strength of the pellet binder is seen in the durability index of TM 98.12%, SM 97.64%, and SPM 97.35%, respectively. However, these variables did not differ significantly in terms of specific gravity and stack angle. Pellet binders considerably affect the consumption of feed and vary markedly in dry matter, organic matter, and metabolizable energy digestibility. Conclusion: Plant-based pellet binders influence the physical quality and digestibility of pelleted feed in Alabio ducks. TM can maintain physical quality and digestibility compared to SM and SPM as plant-based pellet binders. [J Adv Vet Anim Res 2024; 11(1.000): 93-99]

Objective: In the context of the fast-expanding shrimp farming industry in Sri Lanka, this study aimed to evaluate the distribution and understanding of BMPs, examine the relationship between BMPs and disease outbreaks, and analyze the current antibiotic usage trends through a fact-finding survey. Materials and Methods: A questionnaire survey was conducted in 131 shrimp farms located in Puttalam District in North Western Province, where shrimp farming is thriving in Sri Lanka. The survey was conducted from September to October 2021. In addition, in August 2022 and August 2023, interviews were conducted with shrimp farms in Puttalam district and Batticaloa district, shrimp hatcheries, and export companies. Data were analyzed using descriptive statistics, Probit, and Tobit regression analysis. Results: The item-count technique revealed a significant (p < 0.05) difference in the use of antibiotics without consulting experts, signifying inappropriate use. No aquaculture farmer reported being unaware of BMPs, and among the 45 farmers who attended a BMPs seminar, 30 claimed to possess a good understanding of BMPs. Probit and Tobit regression results revealed that the rate of understanding of BMPs, education level, and obtaining information on the sanitation management of shrimp farming from extension and guidance organizations were inversely associated with both disease incidence in shrimp farming and shrimp discards. Conclusion: Although the use of antibiotics is prohibited in BMPs, the analysis results suggest inappropriate use of antibiotics. The findings indicate that enhanced BMP understanding can reduce disease incidence and shrimp discards, emphasizing the need for incentives to promote BMP adoption and reduce the necessity for antibiotics.

Objective: This study aimed to determine the effects of biologically active substances and electrical stimulation of the uterus in cows on the effectiveness of estrus synchronization. Materials and Methods: Ninety (n = 90) Kazakh white-headed cows were synchronized with two injections of gonadotropin-releasing hormone on days 0 and 9 and prostaglandin F2α on day 7. The cows were divided into six groups and, during the protocol, treated with biologically active substances (Tetramag, Selevetum, antiseptic-stimulator Dorogov 2 fraction, groups 2, 3, and 4). Cows in groups 5 and 6 were treated with the same substances but additionally had electrical stimulation of the uterus, while cows in group 1 were left untreated and served as a control. Results: The results have shown that on Day 0, no differences were observed in E2 concentrations between the groups. However, on the 10th day, a significant disparity was noted in the E2 level among cows in group 6 compared to groups 2, 3, 4, and the control group. Conversely, no significant differences were observed between groups 5 and 6. Likewise, the fertility rate in cows from group 6 was significantly higher compared to groups 2, 3, 4, and the control group, with no significant differences between groups 5 and 6. Conclusion: It can be concluded that the utilization of electrical stimulation of the uterus and the inclusion of certain biological substances during the estrus synchronization protocol demonstrate a positive effect on the reproductive performance of beef cattle in Kazakhstan.

Objective: The purpose of this study was to select the active fraction of red ginger (Zingiber officinale var. Rubrum) for its antioxidant and antibacterial activities against Staphylococcus aureus (AMC 6934), Bacillus subtilis (AMC 7923), Pseudomonas aeruginosa (AMC 8973), and Escherichia coli (AMC 5761). Materials and Methods: A total of 2 kg of dry red ginger rhizome powder was macerated in stages with different levels of solvent polarity to extract the chemical composition within the red ginger powder sample. The extraction process begins with a non-polar solvent (n-hexane) by soaking the red ginger powder sample for 3 × 24 h. Results: The red ginger extract fractionated with methanol produced alkaloids, phenolics, flavonoids, and coumarins, while the fractionation using n-hexane produced alkaloids and triterpenoids only. The fractionation with ethyl acetate produced alkaloids, phenolics, flavonoids, triterpenoids, saponins, and coumarins. The antioxidant activity test was 49.261 mg/l for the ethyl acetate fraction, 146.648 mg/l for the methanol fraction, and 300.865 mg/l for the n-hexane fraction. Conclusion: The ethyl acetate fraction was effectively powerful in inhibiting the growth of Gram-positive and Gram-negative bacteria. All fractions had moderate antibacterial activity; however, the performance of ethyl acetate in the red ginger extract was better than that of methanol and n-hexane.

Objective: To evaluate the effect of water temperature on intramuscular injected alfaxalone anesthesia in carp (Cyprinus carpio). Materials and Methods: Six healthy adult carp (C. carpio) were intramuscularly injected with alfaxalone (2.5, 5.0, or 7.5 mg/kg) at normal water temperature (25°C) and at low water temperature (2.5 mg/kg, 15°C). The respiratory rate, heart rate (HR), and anesthesia depth (AD) were evaluated every 5 min for 30 min after administration and every 1 h after 60 min after injection. Results: The respiratory and HRs did not change significantly upon alfaxalone injection, regardless of dose. However, a dose-dependent increase in AD scores was observed. Furthermore, 2.5 mg/kg alfaxalone injected in 15°C water showed an almost equal anesthetic effect to that of 5.0 mg/kg alfaxalone in 25°C water. Conclusion: Alfaxalone is readily available, and its anesthetic effect in carp was enhanced by lowering water temperature, illustrating the possibility of intramuscular injection of alfaxalone in fish.
