Oat hulls and sugar beet pulp in diets for broilers 1. Effects on growth performance and nutrient digestibility

Abstract We assessed the possibly synergistic effects of dietary fiber (DF) and benzoic acid (BA) in growingfinishing pigs. In total, 96 growing pigs ([Landrace × Yorkshire] × Duroc) with an average initial body weight (BW) of 22.82 (±0.24) kg were selected and provided the dietary supplements based on their BW in a 2 × 2 factorial experiment, with the respective factors being fiber (low vs. high; 140 g/kg, 160 g/kg NSP, respectively) and BA (0, 5 g/kg benzoic acid) in six replicate pens consisting of four pigs per pen. Sugar beet pulp was used as a DF source, at 50 g/kg of the diet. All diets were formulated to contain 14.44 ME MJ/kg and 190 g/kg CP. This experiment was conducted to evaluate the growth performance, nutrient digestibility, and reduction of harmful gases and serum metabolites. There was no significant difference in feed intake and weight gains during treatments. Fiber levels and benzoic acid addition did not affect the dry matter, nitrogen and gross energy digestibility. Also, no interaction was found between fiber level and benzoic acid treatment. There was no difference in NH3, but RSH and H2S gases emissions show significant reduction with fiber and benzoic acid treatment. Serum metabolites, including lipoprotein and cholesterol, were also apparently unaffected by these treatments. Thus, the addition of 50 g sugar beet pulp per kg of growing feed as a DF source and the addition of BA had no significant impact on the growth performance of pigs during the growth period.

Anin saccomobile bag technique was used to determine the rate and extent of disappearance of unmolassed sugar-beet pulp, soyabean hulls, hay cubes and an oat hull–naked oats mixture (67:33, w/w) in the foregut and total digestive tract of ponies. Ponies were administered naso-gastrically polyester mesh bags (60×10×10 mm) containing 350 mg feed, in a 3×4 Latin square design. Bags were collected at the ileo-caecal junction (small intestine bag, SIB) and in the faeces (faecal bag, FB) and their residues analysed for proximate constituents and NSP composition and content. DM disappearances from individual bags were fitted to degradation profiles () and effective degradability values determined. Significant differences (P<0·05) in DM, organic matter and crude protein (N×6·25) losses from SIB were noted between feeds with hay cubes and oat hulls–naked oats > sugar-beet pulp and soyabean hulls. Acid-detergent fibre, neutral-detergent fibre and NSP disappearances were small and varied little between feeds. In contrast, FB losses showed significant (P<0·05) differences for all constituents measured with sugar-beet pulp > soyabean hulls > hay cubes > oat hulls–naked oats. Crude protein losses from sugar-beet pulp and soyabean hulls in FB were significantly higher (P<0·05) than from SIB. FB degradation curves showed degradation to be affected by bag residence time with sugar-beet pulp > soyabean hulls and the effective degradability showed that significantly more (P<0·05) sugar-beet pulp was lost at 40.0 and 60.0 h than for the other three feeds. These results show that sugar-beet pulp and soyabean hulls are rapidly degraded by ponies and could be used as alternatives to hay in equid rations. However, the foregut availability of crude protein from sugar-beet pulp is poor, so a readily digestible source of crude protein should be offered to animals with high protein demands when diets are based on sugar-beet pulp.
