Feed efficiency and carcass and meat quality characteristics of bulls finished on diets containing varied proportions of wheat straw and wet sugar beet pulp

AbstractThe effect of feeding different sources of dietary fibre at varying rates of inclusion on the concentrations of skatole and indole in the backfat of finishing pigs and their subsequent carcass quality was studied. Sugar-beet pulp (SBP) and straw (S) were selected because of their assumed widely differing hind-gut fermentability characteristics. They were individually and in combination added to a diet at three rates of inclusion designed to provide concentrations of 40, 80 and 120 g non-starch polysaccharide (NSP) per kg. The digestible energy (DE) contents varied between the three levels of inclusion of NSP but were formulated to a lysine: energy ratio of 0.625 g: MJ DE with other amino acids being in the same individual proportion to lysine. The nine experimental diets were offered to 10 replicate (five entire males and five females) pigs of initial live weight 55 kg. Food intakes were adjusted between treatment to ensure that energy and nutrient intakes were common. Animals were slaughtered on reaching 85 kg live weight. Adipose tissue was analysed for skatole and indole and meat quality characteristics assessed. No significant differences in performance were detected although carcasses from animals given sugar-beet pulp were significantly fatter. There were significant correlations between the level of skatole in the backfat and the following eating quality characteristics: skatole odour intensity of the fat, abnormal odour intensity of fat, abnormal odour intensity of lean and abnormal flavour intensity of lean with correlations coefficients of 0·656 , 0·709 , 0·496 and 0·523 respectively (coefficients >0.276; P < 0·05). The range in skatole levels in the backfat were attributable substantially to very high levels found in three boars. No significant correlations were found between indole concentrations in the backfat and eating quality characteristics. However no effects of dietary NSP type or inclusion level on the eating quality characteristics of pig meat, with pigs given diets on the basis of equal energy and nutrient intakes, were detected.

The once bred gilt system of production has a number of benefits in terms of feed efficiency and welfare, however the system relies on the production of a quality carcass and acceptable reproductive performance. Previous studies have indicated that welfare might be improved if gilts were ad-libitum fed a diet containing 60% Sugar beet pulp (Stewart et al 1993). There was a suggestion however that reproductive physiology may be put at risk using such a diet. The objective of this experiment was to identify differences in reproductive performance using two different energy sources in gestation and to manipulate nutrition during lactation to study the effect on carcass quality.

Potential Use

There is a considerable current interest in the feeding of high fibre diets to pregnant sows, with a view to gaining both economic and welfare advantages. The potential use of these diets will depend on the extent to which the fibrous materials are fermened in the hindgut, and the subsequent capacity of the products of the fermentation, that is VFAs, to meet the energy needs of the animal. Sugar beet pulp and wheat straw are two ingredients that have considerable potential as feed ingredients for sows. The present experiment was designed to study the extent to which diets containing high level of non-starch polysaccharides (NSP), largely from plain sugar beet pulp (SBP) or wheat straw (WS), influenced nutrient partition and the efficiency of ntrient utilisation in pregnant sows.

In accordance with the technical standard ČSN EN 13229 “Inset appliances for heating including open fires fired by solid fuels – Requirements and test methods” was performed the basic assessment of thermal efficiency and emission parameters of prototype of combustion accumulation stove SK-2 with upper after-burning and nominal heat output of 8 kW. Verified gradually were the bio-briquettes of diameter 65 mm from mixture of wheat straw and 20% m/m of brown coal, wheat straw and 5% m/m of brown coal, wheat straw, mixture of wheat straw and 10% m/m of water and molasses solution, Ecobiopal created with the fermented blend of 33% m/m of digested clean water plant sludge and 67% m/m of wood chopped material, blend of wheat straw and 15% m/m of sugar beet pulp, mixture of timothy hay and 25% m/m of brown coal, timothy grass hay, meadow hay, mixture of meadow hay and 25% m/m of brown coal. The lowest CO emissions, when the limit value of 3000 mg/m3N at 13% of O2 has not been exceeded, determined for more strict 1st class and the highest efficiency at nominal heat performance, i.e. higher or equal to 70% (Class I) have been reached by the briquettes produced from mixture of wheat straw and 15% m/m of sugar beet pulp, timothy hay and mixture of meadow hay with addition of 25% m/m of brown coal. Further were measured NOx and HCl emissions. NOx values were significantly lower than limit values determined for similar combustion of solid biofuel. Higher differences of HCl emissions correlate with various Cl content in fuels. Only the wheat straw briquettes with share of 25% m/m of brown coal have exceeded the limit value by 16%. Other fuels have shown considerably lower values. The results have proved better heat-technical and emission parameters of blended briquettes and are significant also for solid biofuels and solid recovered fuels standardization as well as for increasing efficiency method detection and ecological parameters optimization including HCl emissions.

AbstractThirty-six young fattening bulls from three breeds (Belgian Blue, Limousin and Aberdeen Angus) were fattened over 5 months with fattening diets based either on sugar-beet pulp or on cereals. Fattening performance as well as carcass and meat characteristics were measured. There were few relevant effects of the diets on the parameters. The breeds also showed similar fattening features. However, the BB had higher killing-out proportion and their carcasses presented better scores in terms of conformation and fattening. The meat quality of the breeds differed, especially in terms of luminosity, redness and cooking losses. There were also significant influences of breed on the chemical composition of meat; fat content was lowest in Belgian Blue and highest in Aberdeen Angus. Such specificities could help to allocate breeds in appropriate niches in Belgium.

Although overall intake figures were high, critical levels (~400 g/kg DM) of unmolassed sugar beet pulp (USBP) inclusion suppressed dry matter intake (DMI) in ponies by up to 35% when included in complete pelleted diets made with dried grass (Hyslop, 2002). Dulphy et al (1997) have concluded that horses consume straw-based forages at lower levels than grass or legume-based forages. Given this observation with straw based diets, the objective of this study was to examine DMI, in vivo apparent digestibilities and nutritive values in ponies offered pelleted complete diets made from ground wheat straw and containing USBP at inclusion levels between 400 – 800 g/kg DM.
