Navigating Climate Change: A Review of Policies in Botswana, Africa, and Beyond
No full textThis paper is an insightful perspective analysis of Botswana climate change policies in an effort to establish their effectiveness in relation to regional and international initiatives. For a critical review of both mitigation and adaptation efforts by different countries, the effectiveness is analysed, including their strengths and inadequacies noted, and recommendations made towards enhancing policy coherence and effectiveness. It examines the steps Botswana and other countries have taken to cut greenhouse gas emissions, improve energy efficiency, support the use of renewable energy sources, and implement sustainable land management practices. The paper also delves into Botswana's efforts to build climate resilience, such as creating a National Adaptation Plan and incorporating climate considerations across various sectors
Effect of Aloe vera Gel and Sodium Metabisulphite on Expression of Fibroblast Growth Factor in Incision Wound of Rats
No full textAn incision wound is a wound caused by being sliced. Two ingredients that play a key role in the wound-healing process are glucomannan and acemannan, which are rich in polysaccharides and growth hormones. Growth hormones stimulate fibroblast activity and proliferation. The present study involved 35 Sprague Dawley male rats, aged 2-3 months old and weighing 200-300 grams. The study comprised seven groups including, negative control group (G1), positive control (aquades, G2), betadine 10% (G3), gel base (0.5 mg, G4), gel base + sodium metabisulfite 0.2 gr (G5), gel base + Aloe vera 5% (G6), and gel base + Aloe vera 5% + sodium metabisulfite 0.2 gr (G7). Each group had five replications. Initially, a 4-cm incision was made on the dorsal skin of each rat. The study lasted 15 days with observations made on days 3, 7, and 15. After the observation period, the rats were anesthetized and then terminated to collect skin tissues for microscopic examination. The tissue samples were then stained immunohistochemically to assess fibroblast growth factor (FGF) expressions. The results showed that the highest FGF expression was observed in the 5% Aloe vera + 2% metabisulfite group (G7), while the lowest FGF expression was in the negative control group (G1). It is concluded that Aloe vera L. extract gel at 5% + 2% metabisulfite (G7) significantly enhances the expression of FGF
Antibiotic Resistance Pattern of Escherichia coli Isolated from Layer Chicken in Bali-Indonesia
No full textAntibiotics have been used as growth promoters in the poultry industry worldwide, which might lead to the emergence of anti-microbial resistant bacterial strains. Theoretically, older animals should have been exposed to antibiotics and anti-microbial resistant (AMR) strains for longer periods, which may result in the discovery of more resistant strains. The present study aimed to evaluate the antibiotic resistance of Escherichia coli isolated from fecal samples of layer chicken that showed signs of watery diarrhea. In the current study, 134 fecal samples were taken from the layer chicken farms in Penebel village, Tabanan District, Bali, Indonesia. The chickens were classified into three groups including Group 1 under 7 days of age, group 2 aged 7–30 days, and Group 3 chickens older than one month. The samples were cultured in Eosin Methylene Blue agar. The suspected colonies were stained, and subjected to biochemical tests. Escherichia coli-positive colonies were subjected to a bacteria sensitivity test using multiple antibiotic discs. The result demonstrated multi-drug resistance (MDR) of Escherichia coli, while the isolated Escherichia coli was resistant to the most common antibiotics in layer farms in the study area including kanamycin, enrofloxacin, sulfamethoxazole-trimethoprim, streptomycin, and enrofloxacin. In addition, the present study confirmed that although all sample groups were sensitive to bacitracin, oxytetracycline, and clindamycin, they were resistant to sulfamethoxazole-trimethoprim, kanamycin, and ampicillin.

DETECTION AND PREVALENCE OF Leucocytozoon spp. IN LOCAL CHICKEN BREEDS IN AL MUTHANNA PROVINCE OF IRAQ
No full textLeucocytozoon species are avian haemoparasites with economic impacts on poultry production. The present study investigates the presence of Leucocytozoon in chickens of Al Muthanna province, Iraq. Eighty one blood samples were collected from chickens in Samawah, Rumaitha, Warkaa, and Kidhre regions to examine the prevalence of Leucocytozoon. An infection rate of 6.1 was found among chicken breeds. The study highlighted that the main symptoms of infection were decreased egg production, anemia, and loss of appetite. Notably, infection was more prevalent in the Rumaitha, Khidr and Samawah regions, while no cases were reported in Warka. Treatment methods included primaquine and pyrimethamine alongside care to manage the condition effectively. It is important to mention that the observed prevalence rate in chickens was lower compared to studies on birds in Iraq, where an overall blood parasite prevalence of 15 was documented. This difference could be attributed to factors like habitat variations, vector presence, or differing susceptibility among bird species. Our suggestion for future work can be the application of new programs for diagnosing and controlling parasites in chickens. © The Author(s) 202
EFFECT OF SUPPLEMENTATION OF CACTUS (Opuntia ficus-indica) CLADODES, Acacia saligna, WHEAT BRAN AND COTTON SEED CAKE ON FEED INTAKE, DIGESTIBILITY, GROWTH AND CARCASS CHARACTERISTICS OF GOATS
No full textThe objective of this study was to evaluate the effect of supplementation of cactus (Opuntia ficus-indica) cladodes, Acacia saligna, wheat bran and cotton seed cake on growth, digestibility, intake and carcass characteristics of goats. A randomized complete block design was used in the experiment with 24 yearling central highland goats with an initial body weight of 15.6 - 16.1 kg. The same amount of grass hay (GH) + 150 gDM/head/day wheat bran (WB) was given to all animals. The experimental diets consisted of 80 gDM of cotton seed cake (CSC) as treatment 1 (T1); 45 gDM of CSC + 160 gDM of cactus cladodes (CC) as T2; 45g DM of CSC + 80 gDM of Acacia saligna (AS) as T3; and 45 gDM of CSC + 80 gDM of CC + 40 gDM of AS as T4 (per day per goat). Data were gathered on the goats’ growth, digestibility, intake, and carcass of major organs, edible and nonedible organs. The consumption of dry matter and organic matter was higher in goats fed T2 and T4 than in the T1 group. The dry matter (DM), organic matter (OM) and crude protein (CP) digestibility, average daily body weight gain and feed conversion efficiency were higher in T4 and T3 goats when compared to T2 goats. Goats fed on T4 had higher hot carcass weight and dressing percentage on slaughter body weight basis than T2, T3, and T1 supplemented goats. Generally, the experimental diets improved goats’ performance in descending order (T4 > T3 >T1 >T2). Supplementation of T4 (replacement of 35 gDM of cotton seed cake per day by 40 gDM of Acacia saligna and 80 gDM of cactus cladodes on dry matter bases) could be recommended to improve goat performance. © The Author(s) 202
SOLID STATE FERMENTATION CHARACTERISTIC OF RICE STRAW USING HERBIVORE’S CECUM MICROBES
No full textThis study was aimed at identifying highly capable lignolytic microbes from nature for use in Solid State Fermentation (SSF) of rice straw. The SSF silage was prepared in laboratory scale, as the following treatments: uninoculated (control), Lactobacillus plantarum FCC 123 (LP), fiber-degrading fungi (Aspergillus sp.) from horse cecum (FF), and fiber-degrading bacteria (Enterococcus casseliflavus) from buffalo cecum (FB). Incubation was carried out for a month at room temperature. The observed parameters were: organic acids, water-soluble carbohydrate (WSC), microorganism and nutrient composition. Rice straw SSF that was inoculated with LP showed the highest quality of fermentation, indicated by significant highest lactic acid bacteria (LAB) population, and has the lowest of poor bacteria indicators (coliform, aerobic bacteria, and bacilli). The LP treatment also has the highest LAB content and lowest WSC. Among treatments, FB treatment seems to have given a similar result with LP followed by FF. While the chemical composition seems unaffected by treatments. Compared with the fresh material, all fermentation with and without inoculants has reduced neutral detergent fiber (NDF) and increased acid detergent fiber (ADF), but there were no differences among all treatments. Inoculation of both LP and FB could improve rice straw SSF silage quality, but this system could not improve fiber degradation as well as in liquid state fermentation (LSF). © The Author(s) 202
Landmarks in Quail Coccidiosis Research with Special Scrutiny to the Available Egyptian Literature: A Review
No full textQuails are an important alternative to chicken production for protein sources, offering many advantages over other poultry species. However, raising quail faces certain challenges, such as a shortage of specified hatcheries and the lack of local markets for quail eggs and meat, particularly in Egypt. In addition, there is less interest in quail’s medication and vaccine production. A significant disease affecting the health and productivity of quails is coccidiosis, which is associated with poor feed conversion ratio, lower growth performance, heightened mortality, and high cost of vaccination and treatment. Attention to quail coccidiosis and its clinical forms, diagnosis, morphological characterization, control, and prevention is very critical for improving quail meat and egg production. This review compiles scientific data on quail coccidiosis, with a focus on literature from Egypt, for classification, data analysis, and processing.

Atrial Natriuretic Peptide and Cardiovascular Diseases in Dogs and Cats
No full textThe term biomarker encompasses various biological indicators that objectively reflect a patient’s medical status with precision and reproducibility. These indicators range from basic measurements like pulse and blood pressure to more intricate laboratory tests. Cardiac markers are crucial for accurate and prompt diagnosis of heart diseases in animals. Given the challenge of diagnosing cardiac diseases in small animals due to nonspecific clinical signs, cardiac markers provide quantitative indicators of biological processes. These markers include cardiac troponins for myocardial injury, natriuretic peptides for myocardial function, lipoproteins for serum homeostasis, and markers for inflammation of the cardiovascular system. Among natriuretic peptides, atrial natriuretic peptide (ANP) has emerged as a significant tool in diagnosing and monitoring cardiac diseases. ANP, primarily synthesized in cardiac atria, regulates salt and fluid excretion, counteracts vasoconstriction, and inhibits the renin-angiotensin-aldosterone system, contributing to the maintenance of cardiovascular homeostasis. Additionally, it functions as a biomarker for ventricular hypertrophy and congestive heart failure (CHF) in animals. Furthermore, it protects against hypertension and cardiac remodeling by demonstrating antagonism to the same system. This review addresses the definition of biomarkers within the context of molecular biology, elucidates their multifaceted functions in the animal organism in light of integrative physiology, and explores the pathologies correlated with ANP, with an emphasis on its etiopathogenesis and clinical manifestations. © The Author(s) 202
Effects of Different Seasons on Milk Quality: A Study on Two Cattle Breeds in Rainy and Drought Contexts
No full textThe primary focus of dairy farming in the central region of Peru centers on producers. However, there is limited information on how different altitudinal zones, particularly during rainy and dry seasons, affect milk production. The present study aimed to investigate the effects of the rainy and dry seasons on the physicochemical properties of milk from Brown Swiss and Holstein cattle. A total of sixty cows were selected for the study, comprising 30 Brown Swiss and 30 Holstein. The study was conducted across two distinct seasons, including rainy and dry seasons. All animals received the same semi-intensive management and were fed ryegrass and balanced feed. Each animal provided 500 ml of milk for analysis in the morning. The milk was transported at a temperature of 2 °C, where they were analyzed with the Lactoscan equipment to evaluate protein, lactose, fat, total solids, milk density, freezing point, salts, and pH. Significant differences were observed in the interaction between Brown Swiss and Holstein breeds across different seasons, including rainy and dry periods. Significant differences were observed in protein content, showing a positive effect in the interaction “rain: Brown” a value of 3.50 ± 0.36, while “rain: Holstein” showed 3.14 ± 0.05. Statistical differences were observed in the interactions for lactose content, with rain: Brown at 4.82 and dry: Holstein at 4.37. Similarly, there were significant differences in fat content and total solids for rain interaction of rain: Holsten, and dry: Brown. Nevertheless, no differences were observed in terms of milk density, freezing point, salts, and pH. It is concluded that there was an influence of the interaction between breed physiology and seasonal conditions on milk composition. The results also highlight the impact of season-specific environmental factors on the quality of milk.

Multidrug Resistance in Stray Cats of The North Surabaya Region, East Java, Indonesia
No full textStray cats survive by getting food or drink that is available in the environment, correspondingly, stray cats have relatively high exposure to antibiotic resistance obtained from resistant bacteria found in the environment. The present study was conducted to determine patterns of multidrug resistance and Escherichia coli resistance in stray cats. A total of 50 stray cat anal swab samples were taken randomly from the previously recorded stray cat population in the Surabaya area, East Java, Indonesia. Samples were brought using buffered peptone water. They were cultured on MacConkay Agar differential selective media, and all suspicious colonies of Escherichia coli were examined by biochemical tests. Isolates were then identified, and susceptibility testing was performed according to the Clinical and Laboratory Standards Institute. The results of the resistance test indicated that the multidrug resistance in Escherichia coli bacteria taken from cats was 14.6% (7/48). The high antibiotic resistance of Escherichia coli bacteria in stray cats, which were resistant to many drugs, provides an early warning of environmental health. Environmental health is closely related to animal and human health, especially antibiotic resistance
