- W1567113362 abstract "RIASSUNTO Il presente lavoro rientra in una linea di ricerca volta a valutare fonti proteiche alternative alla farina di estrazione di soia. A tale scopo e stata condotta una prova sperimentale per valutare l’appetibilita, la digeribilita, bilancio azotato e valore nutritivo di diete a base di favino (Vicia faba minor, var. Vesuvio), nella specie ovina. Sono state formulate tre diete con una base foraggera comune: due diete differivano per la diversa presenza di favino (F20: percentuale di inclusione 20% e F38: 38%) e livello proteico (13,8% e 17%) mentre la terza aveva la f.e. di soia (S) quale fonte proteica di riferimento (PG: 15,8%). Per tale prova sono stati impiegati 6 ovini adulti, maschi, castrati, di razza sarda, utilizzando un disegno sperimentale a quadrato latino 3 x 3 con due replicazioni. La digeribilita apparente, con le relative differenze significative, della sostanza secca e risultata pari a 70,0A % per F20, 74,2B % per F38 e 70,0A % per S, mentre quella delle proteine grezze, nello stesso ordine, 73,3A %, 78,0b % e 76,8Ba %. Il bilancio dell’azoto e risultato positivo: 7,7a g/d per F20, 9,0b g/d per F38 e 9,2b g/d per S. Il valore nutritivo delle tre diete e risultato pari a 0,82A UFL/kg (F20), 0,90B UFL/kg (F38) e 0,84A UFL/kg (S). I risultati indicano che il favino puo validamente sostituire la farina di estrazione di soia nell’alimentazione degli ovini. SUMMARY The aim of the present work was to evaluate palatability, apparent digestibility, nitrogen balance and nutritive value of diets based on different level of Vicia faba minor comparing to soybean meal. Six Sarda breed wether were used in a two replicated 3 x 3 Latin Square design. Animals were fed in three periods with three experimental diets. Diets were formulated on the basis of natural meadow hay. Two diets contained different levels of Vicia faba: 20% (F20) and 38% (F38) as fed, with a crude protein content of 13,8% and 17% (on dry matter basis) respectively. The third, used as reference diet, was based on soybean meal (S) with a crude protein content of 15,8%. Apparent digestibility values and statistical differences for DM were: 70,0A % (F20), 74,2B % (F38) and 70,0A % (S), for crude protein: 73,3A % (F20), 78,0Bb % (F38) and 76,8Ba % (S). A positive nitrogen balance was observed with the following values: 7,7a g/d (F20), 9,0b g/d (F38) and 9,2b g/d (S). Nutritive value of diets was: 0,82A milkFU/kg (F20), 0,90B milkFU/kg (F38) and 0,84A milkFU/kg (S). Results showed that Vicia faba minor can be used to replace soybean meal in sheep." @default.
