EFFECT OF THE ADDITION OF CALCIUM FORMATE ON FERMENTATION CHARACTERISTICS AND ON NUTRITIVE VALUE OF BARLEY (HORDEUM VULGARE L.) SILAGE – The effect of addition of a commercial product (Serbosil) containing calcium formate (0.3% of forage as fed) on the fermentation and digestibility of barley silage was studied. The apparent digestibility was evaluated (at maintenance and “ad libitum”) with 6 castrated male sheep, according to ASPA methods. The addition of Serbosil favoured the fermentation process with respect to the control. In fact the treatment improved lactic acid production (5.38% vs 6.29%) and showed down propionic and butyric acid (0.35% and 0.57% vs 0.16% and 0.21%) and ammonia N as percentage of total N (11.56 vs 9.28). NDF and ADF digestibility were higher (P<0.001) in treated silage (NDF: 50.51 vs 54.13; ADF: 38.72 vs 43.79), whereas CP (55.08 vs 47.59) and NFE (68.58 vs 65.06) had apposite trend. The silage nutritive value (0.78 Milk FU/kg DM; 0.74 Meat FU/kg DM) was not affected by the treatment.

Abstract
EFFECT OF THE ADDITION OF CALCIUM FORMATE ON FERMENTATION CHARACTERISTICS AND ON NUTRITIVE VALUE OF BARLEY (HORDEUM VULGARE L.) SILAGE – The effect of addition of a commercial product (Serbosil) containing calcium formate (0.3% of forage as fed) on the fermentation and digestibility of barley silage was studied. The apparent digestibility was evaluated (at maintenance and “ad libitum”) with 6 castrated male sheep, according to ASPA methods. The addition of Serbosil favoured the fermentation process with respect to the control. In fact the treatment improved lactic acid production (5.38% vs 6.29%) and showed down propionic and butyric acid (0.35% and 0.57% vs 0.16% and 0.21%) and ammonia N as percentage of total N (11.56 vs 9.28). NDF and ADF digestibility were higher (P<0.001) in treated silage (NDF: 50.51 vs 54.13; ADF: 38.72 vs 43.79), whereas CP (55.08 vs 47.59) and NFE (68.58 vs 65.06) had apposite trend. The silage nutritive value (0.78 Milk FU/kg DM; 0.74 Meat FU/kg DM) was not affected by the treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
