# Clarifying issues related to valorisation

Nutritional recommendations obtained as result of fodder effects assesing at ruminal level.

in vitro trial were hiderlight a wide range of organic substance digestibility for 15 byproducts

studied (from 22.53 for grape seed meal to 81.82% for sesame meal), which allow us to valorise each of

them in vary strategy. The condition is that byproduct to be available in sufficient quantities (especial

for linseed and camelina cake, etc.).

Analises of ruminal parameters (dynamics pH, dynamics NH3, dynamics fatty acids volatile – total and

individual) obtaining by replacement of sunflower meal with camelina cake and linseed on fistuled ram.

We didn’t noticed relevant differences between groups which lead to conclusion that both camelina

and linseed cake could replace sunflower meal without negative influence on ruminal metabolism.

Analises of ruminal parameters obtained by using enzymatic mixture 1 and 2 at

fistuled ram in diet with dry grape pomace (15,5% in DM) didn’t highlight effects nu au

relevat notable efects on ruminal used of heavy digestible byproducts.

As fallow of PCR analyses of ruminal content samples from both experiments on

fistuled animals (diet 1 with camelina and linseed cake; diet 2 with dry grape pomace,

with or without addition of enzymes) certain changes were noticed on bacterial

population. These changes did not lead to major changes of main parameters, rely on

ruminal metabolism (pH, concentration of NH3, fatty acids volatile concentration).

Coriander and linseed cake were analysed in vitro. The protein value – 15.70% (coriander cake)

and 35.50% (linseed cake).

Digestibility coefficient of organic substance was comprised between 42,21% (coriander cake)

to 63,89% (linseed cake).

This allow us to apply different feeding strategy depending on the farmer’s need, market

availability, etc., for their valorisation in animal feeding as alternative resources. These feed

have potential effect on milk nutritional quality and on health status.

The surface cultivated with linseed and camelina could be extended. As a consequences, the

increase the available quantities for animal feeding.

Scientifical events

• By activities of this project was generated a wide range of new acknowledge on using at

ruminal level of some processing by-products (camelina cake, linseed cake, hempseed

cake).

• Assessing of the effects of dietary incorporation of this ingredients in ruminants feeding

highlight new nutritional solution for farmers (diets formula, compound feed structure,

nutritional recommendation).
