The eggs were sprayed with different solutions while the larvae were fed on the sugar cane pieces after being dipped in the solutions for 20 seconds. The results of statistical analysis showed superiority the plant oils from orange and lemon showed remarkable mortality (p≤ 0.05) in the number of dead larvae and non-hatched eggs followed by eucalyptus, basil and Castor while other treatments recorded low number of mortalities of larvae and non-hatched eggs. The L.S. D values (2.49 ,6.19) for eggs and larvae respectively, showed that there were significant differences between oils and significant differences between concentrations. orange and lemon oil showed the strongest effect at 9% followed by the other concentrations, while k1 and k2 oil had no significant difference with the control at 1%.

The data revealed that oil seeds could be considered as a rich source of oils and proteins. Phenolic compounds contents of raw oil seeds were; 978.4, 968.0, 862.75, 915.0 and 1063.4 mg/100 g, while, tannin contents were; 510.0, 490.0, 457.0, 457.0 and 440.0 mg/100 g on dry weight basis in peanut, sesame, soybean, safflower and sunflower, respectively. All processing treatments reduced the phenolic compounds except dehulling of sunflower seeds which was increased by 9.6%. Dehulling of oil seeds reduced tannin content by 9-26.5%, while during cooking processes, tannin leaching out in cooking water resulted in a reduction in its content by 4.5-19.6% for ordinary cooking and 5.2-20.2% for pressure cooking. Germination and fermentation processes decreased tannin by 12.5-34.7 and 13.6-49.0%, respectively. Microwave heating treatment had an effect in removal of tannins from seeds than other cooking methods. The reduction ranged between 8.8-24.4% of its initial content in raw oil seeds.

This review gives an overview of the roles of betaine as a feed additive on the performance, carcass, meat quality in livestock production. Biological functions of betaine are defined as an osmolyte, methyl donor, and carcass modifier. As an osmolyte, betaine regulates the cellular hydration status and alleviates osmotic stress. As a methyl donor, betaine plays an important role in methylation reactions. Therefore, betaine may partly replace other methyl donors such as choline and methionine in the diet. Betaine is also supposed to play a significant role in lipid metabolism and has lipotropic effects also participating in the protein synthesis. A review of the results of this study suggests that betaine supplementation was effective to improve the average daily gain significantly, increased feed consumption and improved efficiency of food utilization of ruminants and monogastric animals. Betaine has been characterized as a carcass modifier by increasing the lean carcass percentage and decrease fat percentage by reducing lipid deposition. In conclusion, this study implies that dietary betaine supplementation was efficacious on growth performance and carcass characteristics of livestock.}, keywords = {Betaine,livestock,meat quality,carcass characteristics}, url = {https://svuijas.journals.ekb.eg/article_67118.html}, eprint = {https://svuijas.journals.ekb.eg/article_67118_ea5165238a138f3c1766c21c9c804c59.pdf} } @article { author = {Aly, M and Osman, K. and Mohanny, K. and Alhousini, E.}, title = {Impacts of new artificial diets on activity and strength development of Apis mellifera honey bee colonies}, journal = {SVU-International Journal of Agricultural Sciences}, volume = {1}, number = {2}, pages = {43-53}, year = {2019}, publisher = {South Valley University, Faculty of Agriculture}, issn = {2636-3801}, eissn = {2636-381X}, doi = {10.21608/svuijas.2019.67122}, abstract = {One of the chronic problems that pose a serious threat for honey beesˈ continuity and survival is pollen and nectar deficiency caused by annual weather fluctuations.

Three new artificial diets were prepared, diet W: based on wheat germ, diet S: based on soya beans and diet M: based on a mixture of equal proportions of wheat germ and soya beans.

Outstanding palatability rates were reported for examined diets, especially for diet S.
