Abstract

Encapsulated cardamom waste extract (ECWE) contains flavonoids with antibacterial and antioxidant properties that may enhance broiler health and performance. This study evaluated the effects of ECWE as a phytobiotic on broiler intestinal microbiota, pH, H/L ratio, lymphoid organs, and performance. A total of 200 unsexed Ross broilers (8 days old) with an average body weight of 215.08±5.1 g/bird were assigned to five dietary treatments: T0 (control), T1 (0.02% ECWE), T2 (0.04% ECWE), T3 (0.06% ECWE), and T4 (0.08% ECWE). Results showed that 0.08% ECWE significantly increased lactic acid bacteria (LAB) populations, lymphoid organ, and broiler performance. The increase in LAB given 0.08% ECWE is more effective in helping to reduce intestinal pH and to minimize the growth of pathogenic bacteria that can interfere with chicken digestion. In addition, the antioxidant properties in ECWE had a positive effect on the development of lymphoid organs, especially the thymus. It is concluded that ECWE supplementation at 0.08% was the most effective in improving digestive tract health and optimizing broiler performance.

Abstract

Post-mining lands, especially abandoned gold mining areas, present serious challenges for agriculture and forage cultivation due to poor soil fertility, heavy metal contamination, and damaged soil structure. To address these issues, this study evaluated the impact of gamma irradiation on the agronomic traits, nutritional content, anatomical characteristics, and in vitro digestibility of dry matter, organic matter, and fiber fractions of Pennisetum purpureum cv. Mott grown on degraded post-gold mining soil. A completely randomized design was used, applying seven doses of gamma rays (0, 5, 10, 15, 20, 25, and 30 Gy). Initially, irradiated plants were cultivated under optimal soil conditions. Selected cuttings were then transplanted onto post-mining soil for two months. Variables observed included growth performance, proximate composition, fiber fractions, macro minerals, and digestibility (dry matter digestibility [DMD], organic matter digestibility [OMD], in vitro digestibility [IVD], neutral detergent fiber digestibility [NDFD], acid detergent fiber digestibility [ADFD], cellulose digestibility [CeD], hemicellulose digestibility [HmD]). Results showed that a moderate dose of 10 Gy significantly enhanced dry matter digestibility, in vitro digestibility, and fiber degradation, accompanied by increases in crude protein and mineral levels. Anatomically, beneficial changes such as thicker mesophyll and vascular tissues were observed at this dose. While the 20 Gy dose also showed improvements in some fiber digestibility parameters, it did not provide an optimal balance with productivity, which was better achieved at 10 Gy. Multivariate analysis revealed distinct treatment clustering, reflecting physiological responses to irradiation. Cultivars treated with 10 Gy exhibited an optimal balance between productivity and forage quality. These findings suggest that gamma irradiation can successfully induce advantageous mutations, improving both adaptability and nutritional value of P. purpureum on marginal soils. In particular, a dose of 10 Gy is promising for breeding superior forage cultivars for the reclamation of post-mining land.

Abstract

In dairy cattle, ingestive behavior is influenced by environmental, nutritional, and management factors. The objective of the study was to describe the ingestive behavior and productive performance of dairy cows in two contrasting dairy production systems in Colombia: a lowland system at 941 m above sea level (a.s.l.) with Lucerna cows, and a highland system at 2500 m a.s.l. with Holstein cows. The temperature-humidity index (THI), forage and water intake, as well as behavioral patterns, were monitored under each system. In the lowland system, the THI values exceeded 85 during afternoon hours, reaching emergency levels; however, Lucerna cows exhibited no clinical signs of heat stress, suggesting thermal resilience. In the highland region, THI remained within the alert range (72-79). Dry matter intake (DMI) as a percentage of body weight was 2.42% in the lowland system and 1.68% in the highland system. Feed efficiency was lower in the lowland system (69.56%) than in the highland system (96.67%). Milk yield per unit of metabolic body weight (BW0.75) was 0.119 kg/kg BW0.75 in the lowland system and 0.206 kg/kg BW0.75 in the highland system. Water intake per 100 kg of body weight was 13.31 L in the lowland system and 16.12 L in the highland system. Forage quality was superior in the highland system, with greater crude protein levels and lower fiber content. Both systems showed metabolizable energy deficits, which increased when accounting for energy expenditures associated with walking. These findings underscore the critical need to tailor management strategies to the unique environmental and nutritional conditions of each production system, thereby enhancing animal welfare and optimizing productivity.

Abstract

Quail farming is vital for smallholder farmers in Central Java, Indonesia; however, productivity often declines due to poor biosecurity, inadequate water quality, and parasitic infections. This study aims to examine biosecurity practices, water quality, and endoparasite loads in ten quail farms (L1-L10) located in Semarang City and nearby regencies. Data were collected through observations, interviews, water sampling, and analysis of quail droppings. Biosecurity scores (maximum 18) were categorized into three groups: Group-1 (scores 13-18), Group-2 (scores 7-12), and Group-3 (scores 1-6). Water quality was assessed based on pH, E. coli, and coliform counts using triplicate samples from each site. The biosecurity score showed that three farms are in Group-1 (L1, L7, L9), five are in Group-2, and two are in Group-3 (L8, L10). The water pH ranged from 4.8 to 8.0; the highest E. coli count was 19.33 CFU/mL (L9), and the highest Coliform count was 89.67 CFU/mL (L5). L1 had the highest parasite load, with Coccidia, Strongyloides, and Ascaridia sp. at 1000 oocysts/g (OPG), 100 OPG, and 33.33 OPG, respectively. Meanwhile, L7 showed no endoparasites or water contamination. Egg production ranged from 64.29% to 90.00%. Although no significant differences in endoparasite prevalence were found among biosecurity groups or water quality (p>0.05), Coliform levels differed significantly (p<0.05), with the highest levels in conventional well-water. This study revealed that only about one-third of smallholder quail farms in Semarang and its surrounding regencies adhere to proper biosecurity measures. It was also the first to document quail endoparasite burdens as well as E. coli and coliform contamination in drinking water.

Abstract

Conventionally, disinfectants based on iodine, hypochlorite, or lactic acid are used in post-dipping for teat hygiene on dairy farms. As a natural alternative for the prevention of bovine mastitis, jurema-preta (Mimosa tenuiflora), copaiba oil (Copaifera martii), and Chlorella vulgaris have antimicrobial and anti-inflammatory properties. Associated with antimicrobial photodynamic therapy (PDT), these substances inhibit Staphylococcus aureus. This study developed two natural emulgels containing these extracts and evaluated their stability, bioadhesiveness, texture, and cytotoxicity for post-dipping to prevent mastitis. The emulgel was developed using Carbopol 934 P (0.25% w/w), jurema extract (12.5% w/w), and Chlorella extract (0.2% w/w), which was dissolved in copaiba oil (4% w/w). Twelve Holstein and Jersey cows were treated with: T1 - control with the use of iodine, T2 - application of emulgel with black jurema and copaiba oil without lighting, and T3 - application of emulgel with black jurema, copaiba oil, and C. vulgaris with lighting. The data obtained in vitro and in vivo were submitted to analysis of variance. For the texture parameters of the emulgel, the formulations showed stability, pseudoplastic behavior, and elastic nature, with no cytotoxic effect. The in vitro study showed that the treatments using light were effective in reducing S. aureus and the extracts were also effective in breaking up pre-formed biofilm by this bacterium. In the in vivo test, there was no significant difference between treatments for somatic cell counts and Staphylococcus in milk and teat swabs. The emugel has antimicrobial potential and can replace iodine for use as post-dipping without cytotoxic effects.

Abstract

Colibacillosis in poultry is induced by avian pathogenic Escherichia coli (APEC). No relevant studies have been extensively published in Indonesia. Colibacillosis can affect various poultry species, resulting in significant economic losses to Indonesia’s poultry industry. The efficacy of colibacillosis treatment depends on the antibiotic sensitivity of the causative pathogen. This study aims to determine the phenotypic traits, pathological pictures, and antibiotic susceptibility of APEC bacteria isolated from colibacillosis cases in commercial farms in the Special Region of Yogyakarta and Central Java. Organ samples were collected from broiler and layer chickens suspected of having colibacillosis. The results of cultured, biochemical tests, pathological examinations, pathogenicity, and hemolysis testing confirmed 21 APEC isolates. The antibiotic susceptibility of the isolates was determined against nine different antibiotics. Pathological examination revealed severe macroscopic changes, including polyserositis (perihepatitis, pericarditis, and air sacculitis), accompanied by microscopic evidence of necrosis and widespread heterophilic inflammatory cell infiltration across the lungs, cardiac pericardium, and ovaries. The resistance patterns of the samples to nine antibiotics, ranked from highest to lowest, were as follows: amoxicillin, enrofloxacin, streptomycin, trimethoprim-sulfamethoxazole, nalidixic acid, oxytetracycline, tetracycline, gentamicin, and neomycin. The highest resistance was observed against β-lactam antibiotics. The APEC isolates displayed high pathogenicity, characterized by typical gross and histopathological lesions of colibacillosis, including polyserositis. Crucially, the high prevalence of multidrug resistance (MDR) against nine tested antibiotics (71.43%), particularly to amoxicillin, poses a serious challenge to effective colibacillosis treatment in the studied regions and necessitates a strategic shift in antibiotic usage policies.

Abstract

This study examined the differences in sperm quality and metabolite profiles among X and Y sperm in Friesian Holstein bulls. It also tried to find specific metabolites that can help improve the accuracy of sexed semen use in humid tropical dairy farms. Semen samples from five bulls were separated by sex and tested for movement, live sperm count, shape, and membrane and acrosome health. The tests used Computer-Assisted Sperm Analysis (CASA) and regular microscope checks. Metabolite analysis was performed using LC-HRMS, followed by various statistical tests, pathway checks, and ROC curve analysis. The outcomes showed that X sperm had better movement and acrosome health, while Y sperm had stronger membranes, fewer shape problems, and moved faster. The untargeted metabolite study showed clear differences between the two groups. X sperm had more identified metabolites and greater average levels. The crucial metabolites found more in X sperm were D-(−)-fructose, L-(+)-lactic acid, and sn-glycero-3-phosphocholine. Meanwhile, Y sperm had greater levels of acetyl-L-carnitine. The pathway analysis showed that X sperm primarily utilized carbohydrate and fat processing through glycolysis and phosphocholine pathways to maintain their movement and membrane integrity. On the other hand, Y sperm mainly use a carnitine-based energy pathway to support their faster and straighter movement. The identified metabolites can serve as reliable biomarkers to aid in laboratory quality control checks and enhance the quality of semen extenders. This outcome gives a good way to make sexed semen more stable and reliable in tropical dairy farming conditions.

Abstract

Second litter syndrome (SLS), defined as an equal or lower number of piglets born alive (NBA) in the second parity compared to that in the first, is a major reproductive concern in commercial sow herds worldwide. This study aimed to identify factors associated with SLS under tropical conditions in Vietnam. Data from 3,957 Landrace × Yorkshire sows farrowing the second litter between 2024 and 2025 were analyzed using logistic regression. The overall incidence of SLS was 56.8%, with mean NBA of 12.7 in both parities. In the multivariable model 1, NBA in the first parity (NBA1) was the strongest predictor, accounting for 50.3% of the explained variation (OR=2.3, 95% CI: 2.2-2.4, p<0.001). Age at insemination after weaning between 344 and 440 days increased the odds of SLS by 1.4-1.8 times compared with the value >470 days. Model 2, excluding NBA1, identified additional risk factors, including litter size at weaning (LSW), weaning-to-service interval (WSI), and month of insemination after the first weaning. Sows that weaned >14 piglets had threefold higher odds of SLS compared to those weaning fewer than 11 piglets (p<0.001). A shorter WSI (0-10 days) increased the risk of  SLS by 1.3-1.4 times compared to a WSI>17 days (p<0.009). Compared with the sows inseminated in May-August, the sows inseminated in September-April had 1.7-2.1 times higher odds of SLS (p<0.001). This study showed a high prevalence of SLS and its association with several factors under tropical conditions. To maintain overall herd productivity while lowering the risk of SLS, farm management should focus on sows with a large NBA1, sows’ recovery before insemination, and the mitigation of metabolic stress.

Abstract

Structural and functional damage during cryopreservation usually impairs the quality of boar sperm, especially post-thaw motility and kinematic performance, which restricts its use in artificial insemination programs. Cholesterol-loaded cyclodextrin (CLC) and moringa leaf extract (MLE) are considered possible cryoprotective additives because they are membrane-stabilizing and antioxidants. The study investigated the possible synergistic effect of the Tris-egg yolk (TY) extender in combination with CLC and MLE on the motility and kinematics properties of thawed boar sperm, as identified in a Computer-Assisted Sperm Analysis (CASA) system. Ejaculates of four healthy boars were diluted with Tris-based extender without or with CLC (1 or 2 mg/mL), MLE (1 or 1.5 mg/mL), or both, and frozen with a conventional protocol. Kinematic variables alongside progressive and fast motility were included as post-thaw tests. The findings showed that combination treatment of 2 mg/mL CLC and 1 mg/mL MLE (T7) resulted in a significant increase in all sperm motility and kinematic variables compared to the control group (T0) (p<0.05). In particular, T7 had better progressive motility (38.04%), fast motility (22.42%), and higher kinematic variables, especially VCL (106.34 µm/s), VSL (36.28 µm/s), and VAP (45.41 µm/s), and better displacement and trajectory indices. T7 was always better than the single supplementation and other combinations. Finally, the addition of CLC (2 mg/mL) and MLE (1 mg/mL) into the Tris egg yolk extender could be a successful approach towards optimizing semen cryopreservation in boars.
