چکیده انگلیسی
Molassed sugar beet pulp (Bp) is a human inedible by-product of the sugar industry being a suitable dietary energy alternative to grains particularly in terms of increasing the net food production efficiency of high-producing dairy cattle. However, there are concerns that feeding large amounts of Bp can limit cow's feed intake, jeopardizing both the production performance and metabolic health especially of high-producing dairy cows that have high energy needs. In the present study dietary inclusion of Bp as a substitute for maize grain was tested in a longitudinal block-randomized experimental design in early lactation high-yielding Simmental cows. The Bp inclusion rates were 0â¯g/kg (i.e., no Bp inclusion as control), 120â¯g/kg (12Bp), or 240â¯g/kg (24Bp) on a dry matter basis. The replacement of maize grain with Bp reduced the human edible input from 135.4â¯MJ GE/d in the control diet to 50.7â¯MJ GE/d in the 24Bp diet (Pâ¯<â¯0.001). Feed and energy intake (Pâ¯=â¯0.693), milk yield (Pâ¯=â¯0.457) as well as energy corrected milk (Pâ¯=â¯0.425) were maintained constant throughout the trial. As a result dietary inclusion of Bp turned a net food loss with feeding the control diet into a net food gain with dietary inclusion of 120 and 240â¯g/kg Bp (Pâ¯<â¯0.001). The energy balance and blood metabolites were unaffected by the dietary treatments (P>â¯0.05), whereas dietary fibre digestibility was linearly improved (Pâ¯=â¯0.038) with Bp⯠feeding, indicating enhanced rumen health and functioning with Bp feeding. In conclusion, feeding molassed sugar beet pulp as partial substitution of maize until 240â¯g/kg is a viable alternative that can improve net food production without impairing the cows' production performance and the metabolic health status of cows while improving the digestibility of fibre.
