Cattail (Typha domingensis) silage improves feed intake, blood profile, economics of production, and growth performance of beef cattle

Abstract

Sixteen Rahaji breed beef cattle (112.00 ± 0.15 kg body weight (BW)) were randomly assigned to one of four rations differing in the degree of substitution of sorghum straw with Cattail (Typha domingensis) silage. Growth performance, feed intake, blood profile, and economics of production were evaluated. Completely randomized design was used, and the feeding trial lasted for 42 days. Cattle were fed a total mixed ration of roughage:concentrate (400:600) g/kg dry matter and gamba hay free choice. The control diet (T0) contained 400 g/kg sorghum straw, expressed on a dry matter basis (DM). For additional treatments, Typha silage (TS) was included at 100 (T10), 200 (T20), and 300 (T30) g/kg of the mix replacing an equal DM weight of sorghum straw. Growth rate was similar (P > 0.05) regardless of the TS level. DM (5160.77–5524.96 g/d) and crude protein (846.36–955.82 g/d) intakes were higher (P < 0.05) in T20 and T30 diets, while the acid detergent fiber intake (471.27–512.46 g/d) reduced (P < 0.05) in TS-based diets. Red blood cell concentrations of cattle fed TS-based diets increased (P < 0.05). The mean corpuscular hemoglobin concentrations of cattle fed T20 diet decreased (P < 0.05) in comparison with the control. Sodium and albumin concentrations were higher (P < 0.05) in cattle fed TS-based diets. Total cost of feeding ($ 49.60–61.62) decreased (P < 0.05) in TS-based diets, while the gross benefit of cattle fed 300 g/kg TS diet ($ 74.98) was enhanced relative to cattle fed T0 and T10 diets. TS can be considered a new resource of feed for cattle.
