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:	The effect of mtor and related signaling pathway on ageing in birds / Mequanint Gashew, Achenef, Adam Lendvai, Levente Czegledi
Dátum:	2024
Megjegyzések:	An organism's lifespan is governed by the mechanistic target of rapamycin (mTOR) and insulin-like insulin growth factor signaling (IIS) pathways. This review seeks to explore the influence of mTOR and its related signaling pathways on the ageing process in avian species. In birds, this pathway plays a crucial role in regulating physiological effects, longevity, and the ageing phenomenon. Both rapamycin and dietary restrictions have demonstrated the ability to inhibit mTOR, leading to an extension of the maximum lifespan in model organisms. Ageing is charac-terized by a gradual decline in physiological function, impacting overall performance, increa-sing susceptibility to death, and diminishing life expectancy. Addressing this issue through mTOR inhibition via dietary restriction and rapamycin administration, as observed in model organisms, presents a potential solution. Despite similarities, a physiological paradox exists between mammals and birds. Additionally, it is reasonable to infer significant differences in the physiological systems of birds compared to mammals. Variations in how sexes allocate resour-ces to different aspects of reproduction can contribute to differences in longevity and ageing, driven by trade-offs in life history. Despite the limited research conducted on birds ageing, the potential impact of mTOR modulation through interventions remains an intriguing area for furt-her exploration.
