Megjegyzések:	This study investigates the effects of three different feeding regimes (25% arginine supplementation, 25% arginine restriction, and standard National Research Council-recommended feed) and sex on the performance of grower Japanese quail for fourteen days trial. The total number of quail was 151, with 81 females and 70 males. A two-way analysis of variance was performed to evaluate the interaction between feed type and sex on live weight. The results show a significant (p < 0.001) effect of feed treatment on final live weight and body weight gain, while sex did not significantly (p > 0.05) affect final live weight or weight gain. The findings revealed that quail fed with 25% arginine-restricted diet had significantly (p < 0.001) lower live weights (126.99 ? 2.41) compared to those subjected to 25% arginine supplementation (144.05 ? 1.60) and control feed regime (140.6 ? 1.88). Furthermore, no significant (p = 0.74) interaction between feed type and sex on live weight was observed. The results also indicated a significant (p = 0.02) effect of feed type on feed intake. These findings suggest that dietary arginine levels critically influence live weight changes in grower Japanese quail, while sex does not exert a significant impact. The insignificant interaction between feed type and sex indicates that arginine levels affect live weight in a similar way for both males and females. This study provides valuable insights for optimizing dietary arginine levels to enhance live weight, body weight gains and feed intake performance in grower Japanese quail.

Cím:	Assessment of backfat thickness and its relationship with reproductive performance of sows ? preliminary findings / Thabang Godfrey Motaung; Joab Malanda Osotsi; Mequanint Gashew; Sawadi F. Ndunguru; Gabriella Novotni-Danko

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.

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.
