Nowadays foods are not purposed to only fulfill hunger and to supply vital nutrients for humans but, also to prohibit nutrition-related diseases and improve physical and mental well-being of the consumers. In this respect, functional foods play distinguished role. Therefore, the aim of this study was to examine the effect of addition of whey cheese and oat whole grain powder in biscuits and crackers by different formulae to produce low calorie biscuits and crackers, and to evaluate their effectiveness on weight gain and lipid profiles in rats fed on a high-fat diet. Feeding rats on different biscuits and crackers formulae recorded reduced body weight gain, adipocyte histological alteration. Feeding rats led to a significant reduction in the levels of LDL and total cholesterol and an improvement in the HDL levels.In conclusion, consumption of whey cheese and oat whole-grain in form of low calorie biscuits and crackers formula reduced the adipocytes histological changes, resulting in reduction of the body weight of the rats.

The objective of this research is to investigate the effect of the introduction of hydroponic barley; produced as feed supplement in the ration, on the performance of feedlot calves. This study was performed in the Taroudant region (South of Morocco), during a trial period between July and October 2017). A total of 100 calves were used in a feeding trial, which were divided into two groups. The calves of the first group received a total mixed ration (control), while the calves of the second group received a similar ration with the addition of hydroponic barley.Similar growth performance is observed for the two groups, which is easily explained by the equivalent rationing. In the finishing phase, however, a higher average daily gain is observed for the group fed with an enriched diet in hydroponic green fodder. In fact, the average daily gain for this group amounts to 1.48 Kg/Day compared to 1.42 Kg/Day for the control group.The slaughter results confirm those noted in terms of growth performance, with a relatively similar carcass yield for the two groups.However, since hydroponic fodder reveals a positive impact especially at the level of the finishing phase, it seems judicious to introduce it in the key phases of fattening and finishing in order to perfect the weight gain of the species benefiting from this contribution.The test results suggest that hydroponic barley based rationing is to deepen, and that it would be desirable to repeat the experiment by testing different levels of hydroponic barley intake, adjusting both the type and the level of complementation, with a more accurate monitoring of feeding.
