Detection of FimH gene of Klebsiella pneumoniae isolate from quail cloacal swab in Surabaya city market
Quail is an alternative poultry besides chicken but is susceptible to various diseases, one of which is Klebsiella pneumonia infection. K. pneumoniae bacteria have 4 well-known virulence factors, namely fimbriae, capsules, lipopolysaccharides (LPS), and siderophores. Fimbriae are hair-like proteins that extend from the cell surface. In K. pneumoniae, Fimbriae promote attachment to non-biological surfaces. Fimbriae are divided into types 1 and 3 according to the most studied. FimA, the major fimbriae subunit, FimH, and the minor apical adhesion protein make up type 1 fimbriae. FimH contains mannose and encourages adherence to the host surface. A robust biofilm is formed when bacteria bind to the surface, which is facilitated by increased expression of the FimH gene. The purpose of this study was to detect the FimH gene in K. pneumoniae in the Surabaya City market. A total of 130 cloacal swab samples were taken from five markets in Surabaya (Turi market, Cemara Pabean market, Bratang market, Kupang market, and Benowo market) and then planted on Mac Conkey agar and Gram stained on colonies suspected to be K. pneumoniae. Colonies on MCA media showed a pink color and were mucoid. Gram staining showed Gram-negative bacteria, short rods, single or paired. Biochemical testing was carried out with TSIA and iMViC (SIM, MR, VP, and SCA). Isolation and identification showed that the percentage of K. pneumoniae was found at 10% (13/130). PCR testing detected the FimH gene at 85% (11/13). K. pneumoniae bacteria carrying the FimH gene increase the risk of biofilm formation which can reduce the effectiveness of antibiotics to antibiotic resistance, thus potentially disrupting public health
Impact of Saccharomyces cerevisiae and Sulfaclozine on lipid profile of broilers chicken
The poultry industry plays a major role in satisfying the nation's meat consumption needs. Broiler meat is readily available and reasonably priced. This study sought to determine how Saccharomyces cerevisiae, when co-administered with a sulfonamide derivative (sulfaclozine 30%), affects broiler lipid profiles and protects against deleterious effects. In this experiment, 100 broilers that were 21 days old were split up into five groups. The first group served as a control, and the second group received sulfaclozine (30 mg/kg). Sulfaclozine 70 mg/kg b.w.t. was administered to the third group, followed by 1.5 gm/L of Saccharomyces cerevisiae mixed with 30 mg/kg b.w.t. for the fourth group and 1.5 gm/L of Saccharomyces cerevisiae combined with 70 mg/kg b.w.t. for the fifth group for 20 consecutive days. Lipid profiles were determined at 26, 31, 36, and 41 days of age, respectively. In the fourth and fifth groups treated with Saccharomyces cerevisiae and different doses of sulfaclozine, the lipid profile decreased, except for high-density lipoprotein (HDL). In the second and third groups treated with sulfaclozine, the lipid profile significantly increased, whereas HDL levels decreased. Ultimately, it was determined that Saccharomyces cerevisiae is a secure and efficient method for assessing the adverse effects of sulfonamides

Effects of compacted forage feeding on Indonesian cattle performance during prolonged sea transport
Compacted forage forms such as wafers and pellets are rarely used in Indonesian cattle transport due to the need for feed adaptation. This study aimed to evaluate the effectiveness of forage-based wafers and pellets in improving cattle performance during prolonged sea transport without the adaptation period to the feed. Two tests, both in vitro and in vivo, were conducted to assess feed quality and its impact on cattle performance. The first study evaluated digestibility of treatment and control feeds (straw and Indigofera) in the rumen. In the first experiment, three treatments (T1: straw, T2: indigofera, T3: straw + indigofera) and three repetitions were conducted, with a duplicate test at each repetition. The second study involved 20 cattle divided into four treatment groups with five duplicates each, testing feed efficiency with straw (control), pellet, wafer, and 10% Indigofera wafer supplementation. In the first experiment, it was observed that Indigofera exhibited the highest levels of Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), and gas production, whereas straw production was the lowest (P<0.05). In the second experiment, the wafer feed group exhibited the greatest increase in body weight gain (BWG), as well as the highest levels of feed consumption and drinking water consumption (P<0.05). The study concluded that providing compressed wafer-shaped forage feed can enhance cattle performance during sea transportation
Organic acids as promising alternatives to antibiotics in livestock production: Mechanisms and applications
Livestock production has increased due to the use of antibiotics as growth promoters in livestock farming; nevertheless, this practice has resulted in serious issues with antimicrobial resistance and has an adverse effect on both human health and the environment. Therefore, the search for safe and effective alternatives becomes very important. Conventional antibiotics may eventually be replaced by organic acids such as butyric, propionic, acetic, and formic acids. These substances reduce the number of harmful microorganisms without affecting the good intestinal flora by lowering the pH of the gastrointestinal tract, breaking down the cell membranes of harmful bacteria, and preventing the action of crucial enzymes. Numerous studies have demonstrated that adding organic acids to livestock feed or drink can enhance the immune system, growth performance, and digestive health of animals, particularly pigs, cattle, and chickens. Its effectiveness is influenced by the type of acid, dose, dosage form, and digestive environmental conditions. In practice, organic acids can be used alone or in combination, as well as in conjunction with probiotics or prebiotics to maximize their synergistic effects. Although encouraging, obstacles still need to be addressed, including the stability of organic acids in feed, individual animal response variations, and production costs. Further research is needed to optimize effective usage strategies, dosages, and formulations. Therefore, organic acids present a potentially secure, effective, and sustainable substitute to lessen the livestock industry's need on antibiotics
