A study to examine the impact of selenium forms on productive traits and egg selenium deposition in Aseel was conducted. A total of 96 selenium-treated 21-week-aged Aseel birds were used, 84 females (1726.25 ± 121.65 g) and 12 males (1973.17 ± 182.84 g) from Lakha, Mushki, Peshaweri and Mianwali varieties. Birds were distributed into four experimental groups (21 females and 3 males/variety), further subdivided into three treatment groups A, B and C with 8 birds each, 7 females and 1 male (4 varieties Â3 Se treatments Â8 birds/treatment). Group A and B were the experimental while, C was a control group. Ration for the birds of group A included 0.3 ppm Se-enriched yeast, group B with 0.3 ppm sodium selenite, while, group C received a basal ration containing no selenium. Experimental birds were maintained separately in battery cages from 22 to 42 weeks. The pullets received Se-enriched yeast (organic source of selenium) supplemented ration gained the sexual maturity earlier (168.61 ± 0.64 d) and represented increased (p .05) body weight (1973.56 ± 3.43 g); egg production (38.17 ± 1.27%); egg mass (112.52 ± 2.63 g); FCR/dozen eggs (3.26 ± 0.06); FCR/kg egg mass (6.77 ± 0.23) and the selenium contents in the whole egg (11.70 ± 0.01 lg), in egg yolk (8.31 ± 0.01 lg) and in egg albumen (3.33 ± 0.01 lg). It is concluded that Se-enriched yeast is more potent than sodium selenite and is a key supplement used to improve production performance and egg-selenium status of Aseel. ARTICLE HISTORY

The aim of this study was to identify the digital library services for visually impaired (VI) students, studying in the University of Karachi. The VI students have the same information needs as that of sighted people but digital information services are not available for them. The VI students have been facing problems in searching information on the internet because they can not use computer and internet without the support of a helper or some specific software or hardware. The researchers collected data by interviewing VI students. The findings show that the VI students had a keen interest in using digital information through digital libraries because they were aware of the importance and usefulness of digital information and wanted to get benefit of that in their education.
