Better welfare for the sows is indicated by optimal body condition, although achieving sufficient output is also necessary, especially in herds with high production levels. Compared to visual grading, backfat thickness evaluation is regarded as a more objective and reliable method of evaluating pig body condition. The overall goal of my research was to assess the relationship of backfat thickness pre-farrowing on sow reproduction parameters across different parities. The focus of the study was in selected farms in Hungary and South Africa. The specific objectives were - - - To establish backfat thickness trends pre farrowing for different sow parities to understand their variations To assess the relationship between backfat thickness pre farrowing and reproductive parameters (live born, stillborn and mummies) To compare the backfat thickness trends and reproduction parameters of sows in South Africa and Hungary. The findings demonstrate the impact of management strategies by showing a wide range of production output variability. The thickness of the backfat varied significantly between sows of different parities, with parity 1 sows displaying a higher backfat. These results suggest that at various phases of parity, particular nutrition and care strategies are needed to optimize sow health and reproduction. Maintaining a healthy physical state that encourages ongoing productivity without running the risk of productivity-related problems may become more important as parity increases. Tailored feeding plans based on parity can enhance herd performance and increase reproduction success. According to the study, backfat thickness shows a significant link with mummified and stillborn piglets but a weak negative correlation with live birth rates. Given the positive association of back fat thickness for mummies and stillbirths, particular care strategies are needed. By focusing on preserving ideal physical conditions, producers can improve their total herd productivity and reproductive performance. 35 The data from the South African herd clears demonstrate the change in BFT from farrowing to weaning . The change in BFT as reflected by data is within accepted ranges reported elsewhere. Both data herds (Hungarian and South African) shows that indeed BFT has an effect on the reproduction a parameter( LB, SB, and Mms). Moreover, the South African herd data reveal the effect of parity on the number of piglets weaned.Tétel Szabadon hozzáférhető Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya(2024-06-03) Osotsi, Joab Malanda; Gashew, Mequanint; Balogh, Péter; Novotni-Dankó, GabriellaThis study aimed to assess the level of awareness and adoption of nurse sow management strategies among small-scale pig farmers in Nakuru County, Kenya. The research included a survey of pig farmers who visited the Nakuru Agricultural Show in July 2023. A total of 139 farmers were interviewed within 5 days of the show. The corresponding author interviewed the respondents in a face-to-face engagement, where questions on nurse sow management were initially drafted in English and translated into Kiswahili, i.e. the second language in Kenya. The obtained results indicated that farmers came from two main regions of the county: the northern part (54.7%, 76/139) and the southern part (45.3%, 63/139). Levels of awareness and adoption were insignificant between the two groups (χ 2 , p<0.05). A major obstacle to the adoption of this strategy was identified as feed challenge at 77.7%; (108/139) and market issue at 59.7%; (83/139). This study identified important aspects and limitations that should be considered when developing sustainable productivity development strategies for Kenyan pig farmers. To assist the sustainable growth of small-scale pig production, the authors suggest government measures that shield farmers against exploitation of feed and marketing components, as well as advocating for effective breeding to increase live born.Tétel Szabadon hozzáférhető Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya(2024) Osotsi, Joab Malanda; Achenef, Gashew Mequanint; Balogh, Péter; Novotniné Dankó, GabriellaTétel Korlátozottan hozzáférhető Characterization of dairy farm practices and performance focusing on production and reproduction indices: A case study in a Holstein Friesian - Girolando farm in Baguio City, PhilippinesCapuyan, Cecilia; Novotniné-Dankó, Gabriella; Osotsi, Joab Malanda; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarThe thesis evaluates the productive and reproductive performance of a government-owned dairy farm in Baguio City, managed by the Department of Agriculture, Regional Field Office - Cordillera Administrative Region (DA RFO - CAR). The study analyzes retrospective data from 2020 to 2025, focusing on 25 Holstein Friesian cows bred with Girolando semen. It aims to establish a baseline for dairy farming in the region by examining key indices such as milk yield (MY), lactation length (LL), average daily milk yield (AMY), calving interval (CI), calf birth weight, and calf sex ratios across three lactations. Through qualitative discussions with farm staff, the research also investigates operational challenges like feed availability, labor management, and equipment issues. By developing a systematic database for improved record-keeping, the study identifies strengths (e.g., peak performance in Lactation 2) and weaknesses (e.g., low milk yield and male bias in Lactation 3). It proposes strategies to enhance performance and productivity. Recommendations include optimizing feed quality, standardizing lactation lengths, using high-quality sexed semen, applying lean management principles, and improving equipment maintenance to support the Philippines' Dairy Industry Roadmap goals of increasing local milk production.Tétel Szabadon hozzáférhető Characterization of Removal Reasons for Nurse Sows and the associated Removal due to their Extended Lactation Length in Hyperprolific Farrow-Wean Herds(2024) Osotsi, Joab Malanda; Balogh, Péter; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető Determining the optimal age of breeding gilts and its impact on lifetime performance, Literature review(2019) Osotsi, Joab MalandaTétel Szabadon hozzáférhető Heat-No-Service: Reproductive lifetime performance of gilts inseminated on first versus second observed estrus in commercial piglet producing herds(2020-05-20) Osotsi, Joab Malanda; Balogh, Péter; Novotni Dankó, GabriellaHeat No Service (HNS) is an increasing managerial decision made in commercial piglet producing herds. Performance of gilts has been shown to be influenced by initial decisions made on them at their introduction in the breeding herds. Lifetime Reproductive performance comprising of parity total born piglets and lifetime total born piglets of gilts initially bred on first observed estrus (0HNS) was compared with that of gilts bred on second observed estrus (1HNS). Stored data from Porcitec database consisted of 2.072 gilts bred on first observed estrus (0HNS) and 2.453 gilts bred on second observed estrus (1HNS) totaling to 4.525 gilts. Data was statistically analyzed using the GLM procedure of IBM SPSS version 25. The results showed a significance difference (p<0.001) in lifetime total born performance of gilts bred at 0HNS (mean 93.9) and 1HNS (mean 95.7). There was also a significant difference (p<0.001) of total born piglets in parity 1, 5 and 6 in the 2 groups. There was an observed increased parity total born and lifetime total born when first time insemination of gilts was delayed to second estrus. The findings in this study favor the 1HNS breeding with an overall increased lifetime total born. Gilts inseminated at 1HNS produce 1.57 more pigs for lifetime as compared with those inseminated at 0HNS when observation is made up to P6. Producers in piglet producing herds could re examine their decisions for increased productivity by promoting many gilts into 1HNS but still maintaining the balance between breed targets and production schedules to remain competitive and profitable in the current global swine industry.Tétel Szabadon hozzáférhető Heat-No-Service: Reproductive lifetime performance of gilts inseminated on first versus second observed estrus in commercial piglet producing herds(2020) Osotsi, Joab Malanda; Balogh, Péter; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető Impacts of ethnoveterinary medicine integrated with livestock farm technologies on the performance and antimicrobial resistance of indigenous goats in South Africa - A review(2024) Mthombeni, Lesedi; Osotsi, Joab Malanda; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető Impacts of ethnoveterinary medicine integrated with livestock farm technologies on the performance and antimicrobial resistance of indigenous goats in South Africa –A review(2024-06-03) Mthombeni, Lesedi; Osotsi, Joab Malanda; Novotni-Danko, GabriellaEthnoveterinary medicine and livestock farm technologies represent a junction of innovation and tradition with the aim to accomplish livestock systems that are resilient, productive, and sustainable to meet 21 st century challenges, especially the antimicrobial resistance issue. This article aims to emphasise the impacts of integrating ethnoveterinary medicine with livestock farm technologies on the performance of indigenous goats in South Africa. With the growing concern over antimicrobial resistance in livestock, there is a pressing need for complementary approaches to the health of animals and their productivity. In this review, the aim evaluated whether an integrative approach could offer a sustainable alternative that benefits animal health and productivity while addressing the concerns of antimicrobial resistance. Comparative study designs across multiple indigenous goat farms were used to integrate specific medicinal plants in ethnoveterinary medicine with present-day livestock technologies that are used to monitor the effects on livestock performance indicators and antimicrobial resistance patterns. In the treated populations, the outcomes were indicative of substantial improvements in reproduction and growth rates, and alongside, there has been a notable decrease in the markers of antimicrobial resistance. Therefore, it is proposed that through these discoveries, the integration of these traditional and modern approaches not only improve the performance of indigenous goats but also contribute immensely to the mitigation of risks associated with antimicrobial resistance.Tétel Korlátozottan hozzáférhető Optimal age of breeding gilts and its impact on lifetime performanceOsotsi, Joab Malanda; Novotniné-Dankó, Gabriella; Balogh, Péter; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarThough the present study was an observational analysis of retrospective data records from commercial piglet producing herds, our results could be biased by growth rate of gilts, weight at first breeding and backfat thickness at first breeding which we did not measure. However the present study adds to scientific work by providing valuable findings regarding the significance of age at first breeding and its relation with lifetime performance helping swine producers and veterinarians to put in practice for productivity in the swine industry. Analyzing collected and stored farm data using appropriate statistical tools has proved to provide valuable solutions that could not have been established on a time restricted controlled experiment. Swine producers and veterinarians can now adequately rely on retrospective data analysis to spruce out solutions on the challenges that are facing the swine industry.Tétel Korlátozottan hozzáférhető Optimal age of breeding gilts and its impact on lifetime performanceOsotsi, Joab Malanda; Novotniné Dankó, Gabriella; Balogh, Péter; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarIn swine industry, gilts replace sows as they age for production purposes, hence continued livestock productivity highly depends on viable replacement stock. Management of these gilts early in life affects their future performance and ultimately the profitability of the swine operation. Lifetime sow performance is an important aspect in managing a commercial sow herd, and age of a gilt at first breeding is considered a management decision which affects sow lifetime performance and stayability in the herd. However with varied age range of breeding gilts practiced on various swine farms, this research aimed at understanding optimal age to first breed gilts and its impact on lifetime performance. Variables measured included, parity total born pigs, lifetime total born pigs and reason for culling. Lifetime data was evaluated of gilts breed between 1st Jan 2014 and 31st July 2016 in piglet producing herds of Midwest United States. Data was extracted from porcitec database in Dec 2018 where 15% of the sows were still active in the herds hence excluded from the analysis. A total of 17,558 removed were classified into 6 classes according to age at the first breeding in days 170-190(n=754), 191-211(n=4683), 212-232(n=7123), 233-253(n=3385), 254-274(n=1002) and 275-369 (n=611). Piglet total born obtained from each sow during the lifetime production was significant (P < 0.05) greater for gilts bred between 233-253 days of age at first mating. Gilts that were bred at <233 days appeared to have a higher risk of removal by farrowing productivity as compared to the other groups. However, the results show that the risk of being culled due to health problems and conformation issues increases as the age at first mating is delayed. Overall reproductive failure appears to be the most economical culling reason across all age groups. With this outcome, it was prudent to evaluate the best management decisions for gilt initiation in a herd to maximize her lifetime performance. Results show that gilts mated for the first time at the right age, 233–253 days, are more productive, both in lifetime total born and have a minimal risk of culling due to farrowing productivity. Furthermore inseminating gilts at second estrus proves to have an advantage of 1.57 more lifetime piglets as compared to first estrus insemination. The research therefore established that there was a significant difference (p<0.05) of age at first breeding of gilts with lifetime performance and a significant difference (p<0.001) of lifetime performance of gilts bred on first versus second estrus.Tétel Szabadon hozzáférhető Optimal age of breeding gilts and its impact on lifetime performance(2019) Osotsi, Joab Malanda; Balogh, Péter; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető An overview of swine production and marketing in Africa - Mini review(2024-06-03) Owusu, Desmond; Osotsi, Joab Malanda; Novotni-Dankó, GabriellaPigs are the oldest domesticated animals, though their ancestry is still uncertain because of a lack of archaeological and genetic evidence. Pigs serve a vital role in reducing the demand for livestock and livestock products in most parts of the world. Especially in the African continent, pigs serve as mobile cash implying how easily they can be converted into cash to sort pressing family needs. Pig production in Africa is different from advanced systems of production in temperate countries, however, it has similarities with most of the tropical low and middle-income nations. Pig production in Africa requires attention to enable it to contribute effectively to the growing African population. However, it has been orchestrated with a myriad of challenges including market access. This mini-review is designed in a manner to provide an overview of pig production contribution to livelihoods in Africa and associated challenges with possible appropriate solutions.Tétel Szabadon hozzáférhető Sow and piglet behaviour during lactation: A review focusing on selected behaviour manifested by foster sows and their fostered piglets(2025) Osotsi, Joab Malanda; Prasojo, Yogi Sidik; Astuti, Putri Kusuma; Achenef, Gashew Mequanint; Balogh, Péter; Rátky, József; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető Sow removal patterns in commercial breed-wean herds of Midwest, USA(2019) Osotsi, Joab Malanda; Balogh, Péter; Novotniné Dankó, GabriellaTétel Szabadon hozzáférhető The status of conservation and management of indigenous sheep breeds in South Africa - A review(2024-06-03) Motaung, Thabang Godfrey; Osotsi, Joab Malanda; Mujitaba, Malam Abulbashar; Wanjala, George; Novotni-Dankó, GabriellaIndigenous sheep breeds in South Africa play an important role in local food security and they are adapted to local conditions. Their genetic and cultural values have to be recognised for national importance. The conservation of these breeds is very critical as most of them are already classified as endangered. The South African government has the initiative to attempt the conservation of these animals; however, it comes with several challenges. In addition to funding, breed conservation demands farmers to understand and recognise the role of such breeds in society. This is especially crucial in the rural communal lands where breeds are kept. Farmers that raise indigenous breeds should be taught the necessity of maintaining the purity of these breeds. Indigenous sheep breeds in South Africa are not favored by the commercial farmers and thus they are more vulnerable. This review outlines the nature of sheep farming and the conservation status of four indigenous sheep breeds in South Africa. The effort and challenges that are met in current conservation arrangements are discussed. Moreover, we emphasise on the conservation techniques that are employed in South Africa.Tétel Szabadon hozzáférhető The current status, challenges and prospects of native pig production and large-scale farming in Laos(2025) Xayalath, Somsy; Rátky, József; Ortega, Arth David Sol Valmoria; Osotsi, Joab Malanda; Novotniné Dankó, Gabriella
