Pigs, sheeps and chicken...
Almost all the common domesticated animals were present at the oral presentations about the Animal nutrition and supplementation. The topics covered in the presentations ranged from aspects of grazing, nutritional values as well as digestabilities of various components used in animal feeding.
Mounir Louhaichi presented his efforts to make applicable GPS technology in tracking and recording the spatial and temporal pattern when moving. This approach may help to improve the grazing schedules in order to optimaly use land resources in a more cost-effective and precise way.
How does different feeding supplements influences the performance of milk constitution of Awassi sheeps in Middle Eastern countries? Muhi El-Dine Hilali from international Cener for Agricultural Research in the Dry Areas (ICARDA) presented the outcomes of his research with respect to this question.
The to Prof. Kreutzer unknown tropical legume Mucuna pruriens L. formally known as Velvet Bean was investigated in the study of Vellingiri Vadivel from the University of Hohenheim. It was shown, that the Velvet Bean can be suggested as an alternative component in poultry feed after further investigation of the effects of toxins.
Also in the study of Julieta Torres from the university Nacional de Colombia analyzed the properties of a variety of five different cow beans cultivars with respect to nutritional aspects. Julieta Torres showed that especially the white cultivar of Vigna unguiculata has the potential to subsistute soy bean as part in pig feed.
What effects can be expected when feeding food supplements to fat-tailed sheeps in Mongolia? The results from the study conducted by Sandra Ahnert from the Christian Alberts University show the different effects of food supplementation to intensive and less-intensive grazing regimes respectively. Especially under intensive grazing regimes food supplementation might contribute to more stustainable land resource use, due to lower feed intake rates. As stated by an attendee in the audiance also the origin of the respective supplementation has to take into account.
In the last presentation Edwin Westreicher from the university of Hohenheim outlined the way how two different N- sources affect the digestability of the two tropical grasses tobiatá and sugarcane. He measured the microbial protein synthese as well as the fermentation activity finding that both sources improved the digestability of grasses containing naturally low protein fractions although sugarcane around 35% more proteins compared to tobiatá.
