Megjegyzések:Backfat thickness (BFT) is an important trait that influences reproductive performance in sows. This study investigated the relationship between sow BFT at farrowing and the number of live born (LB), stillborn (SB), and Mummies (Ms) in different parities (P) (1, 2, 3, 4, 5, 6, 7 and 8). Backfat thickness was measured at point P2 (BFT at the last rib, at the junction of the thoracic and lumbar vertebrae 3?5 cm from the midline of the spine (mm). In total, 216 sows were measured on day 109 of gestation (when they entered farrowing). Descriptive statistics showed that the mean BFT was 14.55 mm SEM 0.171 SD 2.576. Parity had a significant effect on BFT, with a Kruskal-Wallis chi-squared value of 22.728 (df = 7, p = 0.002). Post-hoc pairwise comparisons using Dunn's test in R revealed that P1 exhibited a significantly higher BFT than P3 (p = 0.001) and P4 (p = 0.025). Spearman's correlation coefficient indicated a very weak negative relationship between BFT and LB, whereas there was a strong relationship between BFT and SB and Ms. However, the correlations were not significant p>0.05. This finding suggests that assessing the BFT before farrowing is a helpful tool for guiding sow management and pig production. Additionally, these findings offer data that can be used to inform culling policies.

Cím:Sow and piglet behaviour during lactation: A review focusing on selected behaviour manifested by foster sows and their fostered piglets / Joab Malanda Osotsi, Yogi Sidik Prasojo, Putri Kusuma Astuti, Mequanint Gashew, Peter Balogh, Jozsef Ratky, Gabriella Novotni-Danko
Dátum:2025
Megjegyzések:Foster (F) sows are used to nurse piglets from other sows. Nurse (N) sows are used to nurse other piglets after weaning their own piglets during lactation. Sows nursing non-biological piglets can reject or attack unfamiliar piglets. Similarly, N/F sows could fail to recognize the adopted piglets, which may result in delayed or denied suckling. Behaviours such as rejection, aggression, and failure to suckle pose both physical and nutritional challenges to the fostered piglets. Therefore, after collating the literature, this review was able to establish the following: nurse or foster sows showed antagonistic behaviour towards adopted piglets through aggression and discrimination. Similarly, N/F sows terminated nursing bouts more frequently than non-N/non-F sows. Most N/F piglets upon encountering N/F sows showed wandering squealing syndrome with escape attempts. Nurse/foster piglets exhibited more post-teat massage behaviour, a sign of ♭begging for more milk.' Resident piglets frequently attacked fostered piglets through fighting. Management of large litters in pig production entails the use of N/F sows, and the knowledge in this review could help in improving N/F sow production systems, especially on lactational behaviour. Explanations of possible interventions that are likely to reduce negative behaviours among foster sows and their piglets has been given.

Cím:Relationship between sow parity, backfat thickness and weaning outcomes in a commercial farrow-finish swine farm in Hungary / Osotsi, Joab Malanda, Achenef, Mequanint Gashew, Ndunguru, Sawadi F., Novotni-Danko, Gabriella
Dátum:2024
Megjegyzések:Understanding the significance of sow back-fat thickness (BFT) during lactation in maintaining optimal sow productivity is crucial. This study aimed to evaluate the relationship between sow parity, BFT pre-farrowing and weaning, and weaning performance of Large White ? Landrace Hypor sows of different parities. Backfat thickness was measured at point P2. A total of 196 sows of different parities (P) 1-7 were investigated. Variables that were analyzed included BFT D109 of gestation (when sows entered farrowing), BFT D28 (at weaning), and the number of piglets weaned (Wn). Data were analyzed using the Kruskal-Wallis H-Test and Post-hoc pairwise comparisons were performed using Dunn's test in R. The results showed that sow parity had a significant effect on BFT D109 and the number of weaned piglets. Pairwise multiple comparisons revealed that P1 sows exhibited a significantly higher BFT D109 than P3 and P4 sows (P < 0.001). Parity 1 sows weaned a higher (p<0.001) number of piglets than parities 4, 5, and 6. Spearman's correlation was not significant between BFT D109 and BFT D28; however, it had a moderate positive coefficient of 0.538. The number of weaned piglets did not have an effect (p=0.293) on backfat at weaning. In conclusion, this study suggests that assessing BFT prior to farrowing and weaning is a helpful tool for guiding sow management and pig production.

Cím:Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya / Joab Malanda Osotsi, Mequanint Gashew, Péter Balogh, Gabriella Novotni-Dankó
Dátum:2024
ISSN:2416-1640 1587-1282
Megjegyzések:This 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 (?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
