dc.description.abstract | The effects of feeding Atriplex halimus treated with three developed enzyme cocktails to Barki sheep on feed intake, nutrient digestibility, N utilization, and ruminal fermentation were assessed. A. halimus was ensiled with two developed enzyme cocktails of ZAD1® (Z1) and/or ZAD2® (Z2) as liquid enzyme preparations (2 l/t) with 5% molasses and ensiled for 30 days. Three Barki rams (45 ± 3.2 kg) were used per treatment in five consecutive digestibility trials, while three ewes fitted with a permanent rumen fistula were used as source of inoculum for in vitro rumen fermentation trials. Barley grain (300 g/animal/day) was fed as energy supplement during the experimental trial for all diets. Five diets were composed as follows: A. halimus (leaves and stems) (D1); untreated A. halimus plus 4 g/animal/day ZADO® (Z) (enzyme preparation in powder form) (D2); A. halimus ensiled with Z1 and barley plus 4 g/animal/day Z (D3); A. halimus ensiled with Z2 and barley (D3) plus 4 g/animal/day Z (D4); A. halimus ensiled with a combination of Z1 and Z2 (1 :1) and barley plus 4 g/head/day Z (D5). For all trials, ad libitum A. halimus was offered twice a day at 9:00 and 16:00 h while barley grain was given once a day at 10:00 h. Both D1 and D2 diets increased (P <0.001) dry matter intake of A. halimus and total dry matter intake. Addition of 4 g/day of Z to Z1 and/or Z2 ensiled diets improved (P < 0.0001) organic matter, crude protein, crude fibre, and neutral detergent fibre digestibilities. Diets D1 and D2 increased (P < 0.001) N intake, whereas the direct addition of Z to D3, D4, and D5 decreased (P < 0.001) N balance and N balance/N absorption ratio. Sheep fed on Z in addition to Z2 ensiled A. halimus showed higher improvements for total volatile fatty acids (P < 0.001), ammonia N (P = 0.007), and microbial protein production (P = 0.003). It can be concluded that feeding sheep on A. halimus ensiled with Z1 and Z2 with direct feeding of Z enzyme preparation improved intake, digestibility, nitrogen balance and utilization, as well as rumen fermentation. | es |
