EFFECT OF NANOMINERALS ADDITION ON IN VITRO DIGESTIBILITY OF SOME ROUGHAGES

Abstract

This thesis aims at improving the nutritional value of some roughages through the use of nano-technology, when cobalt elements have been added as nano-forms (nano-cobalt) and tested experiments using the method (In –Vitro Gas Production) and the effect of adding cellulose and hemicellulose to dry matter degeneration and production of gas. In the introduction to this study, we presented a review of the deficit issue in meeting the animals' nutritional needs due to the divide between feed resources and their nutritional requirements. Therefore, this research proposal aims to solve this problem, by using rice straw, wheat straw, peanut straw, beans straw, and bagasse sugar cane to increase its nutritional value and assess this in the laboratory, by adding nano-cobalt to the hardening. In the second part of the study, the most significant laboratory steps and chemicals were reviewed and the results were finally discussed. The laboratory part of the study was carried out in the years 2017/2018 in the laboratories of the Department of Animal Production, Faculty of Agriculture, Ain Shams University - Egypt. The first experiment: In vitro gas production technique The standard ration calculated six quantities of nanocobalt. The ration has been supplemented as a standard level according to (NRC 1985) requirements at nanocobalt levels, at a level of 0,25, 50, 75, 100 and 125% for small ruminants (sheep and goats) (0.2 mg/kg DM consumed= 100%). and 100% for cobalt. Both six levels have been diluted into 100 ml of distilled water and subsequently added to the vessels under control. The ration was tested using a mixture of concentrate grain, wheat bran, soy, salt and lime and Egyptian clover hay. In order to prepare the ration the ratio 1:1 (w/w) was applied.
