Molasses from the manufacture of beet sugar enables an improvement in the fermentation quality of beet-pulp silages. An in vivo trial with sheep was carried out at Agroscope Posieux in order to ascertain the digestibility of molassed pulp silages. Adult wethers (n = 4 per treatment; 83.9 ± 9.3 kg average weight) were given rations consisting of 40 % pulp silage (with 0 %, 7 % or 14 % molasses) and 60 % hay of the first cut. In a second stage, they were given 60 % pulp and 40 % hay of the second cut. The coefficients of organic matter digestibility, nitrogenous matter and crude energy did not differ as a function of the molasses content incorporated. The coefficients obtained with 40 % pulp in the ration were greater (p < 0.01) than those obtained with 60 % pulp. Cell-wall constituent digestibility (crude cellulose, lignocellulose and cell walls) differed neither as a function of the amount of molasses added nor as a function of the percentage of pulp in the ration.
While botanical composition, growth cycle and phenological stage are integral factors, they are not the sole determinants of the quality of grass silages from intensively managed permanent meadows.
Food that is unsuitable for human consumption does not affect the growth performance or carcass composition of pigs to which it is fed. This makes it a promising solution for reducing food waste.
Horses are ridden or driven on a variety of surfaces, which differently absorb the impact forces exerted on hooves, limbs and the horse's entire body. Objective measurement of the functional properties of equestrian arena surfaces is therefore of great importance.
