The experiment was carried out at the experimental station of the faculty of Agriculture Al-Azhar University, Cairo Egypt, to evaluate the grape pressing byproducts as a unconventional feed stuff in rations of growing ossimi lambs. A feeding trial of 16 weeks period was carried out with 12 growing ossimi lambs aging 7-8 months and weighing 25.4 kg on the average. The experimental lambs were devided into three groups 4 animals each to represent three nutritional treatments. The first group (G1) control was offered a complete concentrate feed mixture (G1). While the other two groups (G2,G3), were fed concentrate feed mixture plus 15% grape pressing by-products (G2) and the second was offered the feed mixture plus 30% grape pressing by-products (G3) respectively. The bean straw was offered ad-libitum, while concentrated feeds were fed at a rate of 3% of LBW to the three groups. Three digestibility trails were carried out at the end of the feeding trial to evaluate the three rations. Results obtained can be summarized as follows : 1) There were no significant differences among the groups fed diets containing grape pressing by-products is final weight, total gain and daily gains. 2) Conversion of TDN and DCP calculated as kg required for each kg live weight gain were found to be 7.62, 7.38, 6.67 and 1.20, 1.18 and 1.12 for the groups G1, G2 and G3 respectively.3) The highest feed costs for each kg live weight gain were recorded by the G1, followed by G2, and G3 groups; respectively. 4) Treatments applied showed no significant effects on digestibities of DM; OM; CP; CF; EE and NFE.. Further investigation on grape pressing by-products are required especially on the area of treatment of this feed stuff to get red of the tannines presented in it (3-7% of the DM) Also applications of this feed stuff should be studied on the large scale in the practice .

Background: There is a vast growth of Artificial Intelligence (AI) applications across all aspects of healthcare. Nursing practice is critical where AI technology will enhance practice and patient outcomes.The aimof this study was to evaluate the effect of educational program on nurses' knowledge and attitudes regarding artificial intelligence.Design:A quasi-experimental design was used in this study. Setting: This study was conducted atMansoura University Hospitals at medical and surgical departments. Sample: A simple random sample included (203) nurseswere selected from the previously mentioned settings. Tools: Two tools were used to collect the necessary data for achieving the study objective: A self-administered Artificial Intelligence Knowledge Questionnaire and A General Attitudes towards Artificial Intelligence Questionnaire.Results: The primary source of information for nurses' knowledge about artificial intelligence was from Internet (73.9%).The total level of knowledge was satisfactory among 16.3% of studied nurses at pre intervention period, while it was 82.8% at immediately post intervention, and decreased to 68% at follow-up. Additionally, the total positive nurses' attitudesmean score improved from 53.35 ±21.07 at preinterventionto 77.19±18.64 at immediately post and decreased to 67.95±23.62 at follow-up with statistically significant differences. Moreover, highly statistically significant differences between the demographic characteristics (marital status, and educational qualifications) and total knowledge level post intervention (P<0.001). Conclusion: This study revealed that the educational intervention had highly statistically significant positive effect on the studied nurses' knowledge, and attitudes regarding artificial intelligence. Therefore, it is recommended toencourage nurses to increase their knowledge and attitudes toward artificial intelligence through workshops and training programs, and providing further education and training are required to enable them integrate AI into nursing practices.

An experiment was carried out at the experimental station of the Faculty of Agriculture, Cairo University to evaluate fresh Leucaena leucocephala plants and its silage as a unconventional feed in rations of growing Rahmani males sheep. A total number of 12 growing Rahmani rams aging 6-7 months and weighing 28.5 kg on the average were devided into two groups of 6 animals each to represent two experimental groups. The first group was offered barley according to energy and protein requirements plus green Leucaena leucocephala whole plants ad-libitum, while the second group was offered barley (requrements) and Leucaena silage adlibitum. The experiment lasted 12 weeks.Results obtained can be summerized as followes : 1) Group fed on barley plus Leucaena silage showed significantly (P<0.05)superior live body weight compared to the group fed on barley plus Leucaena fresh plants. 2) Significant differences (P < 0.05) occurred on the rumen liquor characteristics (pH, ammonia-N and TVFA's) for the favor of the group fed on barley and Leucaena silage diet. 3) Digestibility coefficients of DM, OM, CP, CF and NFE were significantly higher in the silage fed group compared to the other group. 4) Barley plus Leucaena silage diet showed significantly better feeding values as TDN %, SV%, DCP and N.B, compared to barley plus fresh Leucaena diet.
