It is one of the main causes of huge economic losses due to mortality and decreased production in poultry sector throughout world. This study was conducted to determine the prevalence and antibiogram of <em>Salmonella</em> isolated from retail broiler meat. A cross-sectional study was done from August to September 2023 with a total of 152 samples (106 muscle and 46 liver) from different retail meat shops of Siddharthanagar municipality, Rupandehi and transported to Veterinary Medicine Lab, Paklihawa Campus for further analysis according to standard culture-based methods. Antibiogram of isolated <em>Salmonella</em> was evaluated against five different groups of antibiotics by disc diffusion method following CLSI guidelines. Data was analysed in SPSS using Chi-Square test at confidence level of 95%. The overall prevalence of <em>Salmonella</em> was recorded to be 18.42% whereby prevalence from liver sample was 19.57% and muscle sample was 17.92%. Statistical analysis showed no significant difference in prevalence among the sample types. The antibiogram study revealed that none of the antibiotics showed 100% effectiveness. The most resistance was seen with Ciprofloxacin (89.28%) followed by Ceftriaxone (85.71%), Tetracycline (82.14%), Chloramphenicol (57.14%), and Amikacin (53.57%). 26 out of 28 isolates (92.86%) were found to be multidrug-resistant (≥3 antibiotic groups). The study revealed a higher prevalence of <em>Salmonella</em> in the retail market, highlighting it as a potential public health threat due to the risk of infection from poultry meat consumption. Regular surveillance on antibiotic resistance and justifiable use of antibiotics in the commercial poultry industry is highly recommended.</p> 2025-01-14T00:00:00+00:00 Copyright (c) 2025 Author(s).

The study was carried out to evaluate the comparative effectiveness of four different synchronization protocols on the reproductive performance of Merino ewes during the autumn breeding season. The ewes were inseminated immediately after withdrawal of the treatments as they come on estrus. The indices determined after artificial insemination with semen collected from ram were (a) conception rate and return rate of ewes in different synchronization protocols (b) pregnancy rate and lambing rate of ewes in different synchronization protocols and, (c) sex of lambs and number of lambs born per ewe in different synchronization protocols. A total of 204 ewes were randomly assigned to four treatments: TRT A (Control), TRT B (12 days’ intravaginal sponges [0.3 g P4] insert), TRT C (Double injection of prostaglandin at day 0 and 11), and TRT D (intravaginal sponges for 13 days, single injection of prostaglandin at 12 days together with single injected of pregnant mare serum gonadotropin at day 13. The experimental treatments did not have a significant effect (p≥0.05) on conception rate, returned rate and sex of lambs while, pregnancy rate, lambing rate, ewes aborted and number of lambs born per ewe differed significantly (p≤0.05) between treatments. Merino sheep farmers are recommended to implement estrus synchronization and artificial insemination techniques in their flocks in order to improve the reproductive performance of ewes during the autumn breeding season.</p> 2025-02-08T00:00:00+00:00 Copyright (c) 2025 Author(s).

Mpira K.T. Kabuni kabuni.kabuni@gmail.com <p>This study investigated artificial insemination (AI)'s impact on Tanzanian smallholder dairy farmers' livelihoods. 116 farmers in Muheza district were surveyed using a cross-sectional design.&nbsp; Data analysis employed a Probit model and Propensity Score Matching (PSM) to account for self-selection bias in AI adoption. This rigorous approach allowed isolation of impact of AI from other factors influencing farmer livelihoods. AI adoption significantly improved smallholder dairy farmers' livelihoods, notably increasing daily meal consumption and income. Substantially higher incomes were reported from AI adopters than non-adopters, indicating enhanced economic stability.&nbsp; This improvement is likely due to superior genetics leading to healthier, more productive cattle and increased milk production.&nbsp; Additionally, AI adoption may indirectly boost farming practices through knowledge transfer and support networks. Therefore, to significantly boost food security and economic well-being, the Tanzanian government should prioritize expanding access to superior dairy genetics and high-quality breeding services for smallholder farmers. This targeted investment will dramatically improve livelihoods not only in Muheza district of the Tanga region but also in other rural communities in Tanzania.</p> 2025-02-14T00:00:00+00:00 Copyright (c) 2025 Author(s).
