At the end of the red waste biotransformation an alga Gelidium agar -agar sesquipedale after extraction, we achieved a finished product free of pathogenic bacteria and rich in protein 26%, fat 0.40%, carbohydrate 38% and 11% minerals. Three diets containing respectively 20%, 25%, 30% seaweed waste are compared with a commercial ration to determine the best growth on sheep. We followed the weight gain and average daily gain during the 90 days. Four batches of ten sheep each were submitted to the fattening test. Lot 1 receiving the food (F1) reached an average gain resulting weight of 14.5 kg or average daily gain (ADG) of 161 g / d. Lot 2 receiving the food F2 recorded an average weight gain of 16.3 kg is the equivalent of a daily gain 181 g / d. As for lot3 nourished by the food F3, marked the largest average weight gain of 19.35 Kg, a daily gain of 215 g / d. The control group regarding showed him a mean weight gain of interest near that of lot1 13.3 Kg, which corresponds to an average daily gain of 147 g / d. In addition, microbiological analyzes of sheep carcasses and viscera showed that total mesophilic anaerobic flora varies between 102 and 103 cfu / g and faecal coliforms vary between 1 and 3 cfu / g. Salmonella and clostridia are totally absent. These results confirm the possibility of solving problems due to protein and mineral deficiencies in animals by adding these fermented waste and obtain a clean and healthy meat for consumption.

Abstract: (french)
A la fin de la biotransformation des déchets d’une algue rouge Gelidium sesquipedale après extraction d’agar –agar, nous avons obtenu un produit fini dépourvu de bactéries pathogènes et riches en protéines 26 %, lipides 0,40 %, glucides 38 % et 11 % d’éléments minéraux. Trois rations contenant respectivement 20 %, 25 %, 30 % de déchets d’algues sont comparées à une ration commerciale pour établir la meilleure croissance sur les ovins. Nous avons suivi le gain de poids et le gain moyen quotidien durant les 90 jours. Quatre lots de dix ovins chacun ont été soumis au test d’engraissement. Le lot 1 recevant l’aliment (F1) a atteint un gain moyen de poids obtenu de 14,5 Kg soit un gain moyen quotidien (GMQ) de 161 g/j. Le lot 2 recevant l’aliment F2 a enregistré un gain de poids moyen de 16,3 Kg c’est l’équivalent d’un GMQ 181 g/j. Quant au lot3 nourri par l’aliment F3, a marqué le plus grand gain de poids moyen de 19,35 Kg, soit un GMQ de 215 g/j. Le lot témoin quant à lui a montré un gain de poids moyen intéressant proche du celui du lot1 soit 13,3 Kg ce qui correspond à un GMQ de 147 g/j. En outre, les analyses microbiologiques réalisées sur les carcasses et les viscères ovins ont montré que la flore mésophile anaérobie totale varie entre 102 et 103 ufc/g et Les coliformes fécaux varient entre 1 et 3 ufc/g. Les salmonelles et les clostridiums sont totalement absents. Ces résultats confirment la possibilité de résoudre les problèmes dus aux carences protéiques et minérales chez les animaux par l’addition de ces déchets fermentés et obtenir une viande saine et propre à la consommation.
