This experiment was designed to evaluate whether milk yields could be maintained while reducing concentrate feed intake, and therefore placing greater reliance on forage intake, and including sugar beet pulp as a source of highly digestible but non-starchy concentrate, and fish meal as a source of high quality, undegraded dietary protein. It was undertaken on a commercial farm as the continuation of similar experiments on two other commercial farms reported earlier (Pike et al 1984).

Compound feeds are frequently used at a fixed rate of 0.36kg to 0.40kg/kg milk produced, in addition to forage and other home-grown feeds. Such linear scales take no account of the curvilinear response of milk yield to concentrate feed intake, nor of the substitution effect of concentrate feed upon forage intake. In high-yielding herds, the use of fixed rate scales can result in the provision of concentrate feeds in excess of 10kg/d. An experiment was designed to evaluate whether milk yields could be maintained while reducing concentrate feed intake, and therefore placing greater reliance on forage intake, and including sugar-beet pulp as a source of highly digestible but non-starchy concentrate, and fish meal as a source of high quality undegraded dietary protein

The use of whole-crop wheat harvested at the hard dough (55-65% DM) stage has advantages of high yields of DM, and no effluent production. Treatment with urea prior to storage prevents fermentation or moulding, increases the nitrogen (N) content and may increase digestibility (Deschard et al, 1987; MacDearmid et al, 1988).The objective of this experiment was to investigate the intake and digestibility of urea-treated whole-crop wheat when fed alone, or when supplemented with an energy supplement (molassed sugar beet pulp) and a protein supplement (fish meal).

Abstract This study evaluated the effects of l-carnitine (CAR) and sugar beet pulp (SBP) inclusion in gilt gestation diets on gilt live weight, cortisol concentration, lactation feed intake, and lifetime growth of progeny. Eighty-four pregnant gilts (Large White × Landrace) were randomly assigned to a treatment at day 38 of gestation until parturition; Control (0% SBP, 0 g CAR), CAR (0.125 g/d CAR), SBP (40% SBP), and SBP plus CAR (40% SBP, 0.125 g/d CAR). Gilts were weighed and back-fat depth was recorded on day 38, day 90, and day 108 of gestation and at weaning. Gilt saliva samples were collected pre-farrowing and fecal consistency was scored from entry to the farrowing room until day 5 post-partum. The number of piglets born (total, live, and stillborn) and individual birth weight was recorded. Piglet blood glucose concentration was measured 24 h post-partum and pigs were weighed on day 1, day 6, day 14, day 26, day 76, day 110, and day 147 of life. Carcass data were collected at slaughter. There was no interaction between CAR and SBP for any variable measured. The SBP-fed gilts were heavier on day 90 and day 108 of gestation (P < 0.05) and lost more weight during lactation (P < 0.05) than control gilts. They also had a greater fecal consistency score (P < 0.01). Total farrowing duration, piglet birth interval, and lactation feed intakes were similar between treatments (P > 0.05). The number of piglets born (total, live, and stillborn) and piglet birth weight was likewise similar between treatments (P > 0.05). Piglets from CAR-fed gilts had lower blood glucose concentrations (P < 0.01), while piglets from SBP-fed gilts had greater blood glucose concentrations (P < 0.01). Piglets from CAR gilts had a lower average daily gain between day 1 and day 6 (P < 0.05) and day 14 and day 26 post-partum (P < 0.05) compared to piglets from control gilts. However, CAR gilts weaned a greater number of pigs (P = 0.07). Live weight and carcass weight at slaughter were heavier for pigs from CAR gilts (P < 0.05) and from SBP gilts (P < 0.05). Pigs from CAR gilts (P < 0.01) and SBP gilts (P < 0.05) had increased carcass muscle depth. In conclusion, no benefit was found from the combined feeding of CAR and SBP. Fed separately, CAR increased the live weight, carcass weight, and muscle depth of progeny at slaughter. Feeding a high SBP diet increased fecal consistency in gilts pre-farrowing and increased live weight and carcass muscle depth of progeny.

Results from three previous experiments with finishing cattle on an 18-month beef system indicate that the major increases in daily live-weight gain (DLG) occur within the first 50 to 60 days of supplementation with fish meal. Hence, it may be possible to remove fish meal from the diet after the initial two months of the finishing winter without any subsequent effect on animal performance.For the last nine weeks at grass the experimental cattle were given 1.4-kg/head/day dried sugar beet pulp nuts. On housing this allowance was increased to 3.0 kg and the 48 British Friesian steers were offered grass silage ad libitum (round bale silage for one week and precision-chopped clamp silage thereafter). The 3.0-kg dried sugar beet pulp was given for five days and after a 10-day changeover period the nuts were replaced by 15-kg potatoes. Cattle were offered the basal diet of precision-chopped silage and potatoes for 12 days before starting the experiment.Steers were implanted with 300-mg trenbolone acetate (Finaplix, Hoechst UK Ltd, Milton Keynes) and 36-mg zeranol (Ralgro, Crown Chemical Company Ltd, Lamberhurst) 20 days before randomisation.

Abstract The objective was to determine the influence of feed intake (FI) and fiber source on hindgut disappearance of energy and nutrients in pigs. Ten canulated barrows with an initial body weight (BW) of 38.3 ± 5.4 kg were allotted to a replicated 5 × 4 Latin square design with 5 treatments and 4 periods. A corn-soybean meal-based basal diet (BD) and 2 × 2 factorial treatment arrangement with 2 amounts of FI (9.0 and 4.5% × BW0.75) and 2 fiber sources of sugar beet pulp (SBP) and corn cob were used. Three diets were 1) a BD, 2) a diet replacing 30% of corn and soybean meal in BD with SBP as a source of soluble dietary fiber (SDF), and 3) a diet replacing 15% of corn and soybean meal in BD with corn cobs as a source of insoluble dietary fiber (IDF) to obtain a similar IDF concentration as in the SBP diet. Each period consisted of 7-d adaptation, 2-d fecal collection, and 2-d ileal collection. Apparent ileal digestibility (AID) of energy, dry matter (DM), organic matter (OM), and crude protein (CP) in SBP diet was less (P &lt; 0.001) than that in corn cob diet, whereas AID of neutral detergent fiber in SBP were greater (P &lt; 0.001) than in corn cob diet. Hindgut disappearance of energy, DM, OM, neutral detergent fiber, and acid detergent fiber in SBP diet was greater (P &lt; 0.05) than that in corn cob diet. However, no interaction between FI and fiber source on the AID, apparent total tract digestibility, and hindgut disappearance of nutrients was observed. Overall, hindgut disappearance of nutrients in sugar beet pulp diet was greater than that in corn cob diet. However, the influence of feed intake or the interaction between feed intake and fiber source was not observed.

Abstract The objective was to determine the influence of feed intake (FI) and fiber source on the apparent total tract digestibility (ATTD) of gross energy (GE) and nutrients in pigs. Twelve barrows with an initial body weight (BW) of 34.0 ± 2.6 kg were allotted to a replicated 6 × 4 Latin square design with 6 treatments and 4 periods. The 6 treatments were consisted of a 2 × 3 factorial arrangement with 2 amounts of FI (9.0 and 4.5% × BW0.75) and 3 dietary fiber sources. Three diets were 1) a corn-soybean meal-based basal diet (BD), 2) a diet replacing 30% of corn and soybean meal in BD with sugar beet pulp (SBP) as a source of soluble dietary fiber (SDF), and 3) a diet replacing 15% of corn and soybean meal in BD with corn cobs as a source of insoluble dietary fiber (IDF) to obtain a similar IDF concentration as in the SBP diet. Following a 6-d adaptation, feces were collected for 5 d. The ATTD of GE, dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in diets was greater (P &lt; 0.05) for pigs fed at 4.5% of BW0.75 compared with those fed at 9.0% of BW0.75. The ATTD of GE, DM, OM, NDF, and ADF in SBP diet was greater (P &lt; 0.01) than that in corn cob diet. However, there was no interaction between FI and fiber source on energy and nutrient digestibility. The ATTD of GE, DM, OM, protein, NDF, and ADF in SBP was greater (P &lt; 0.01) than that in corn cobs. In conclusion, energy and nutrient digestibility values were increased by reduced feed intake and were greater in sugar beet pulp than in corn cobs without interaction between feed intake and fiber source.

Previous work has indicated that unmolassed sugar beet pulp (USBP) may suppress voluntary feed intake (VFI) in ponies when offered as the major component; but not when offered as a relatively minor component of the diet (Hyslop et al, 1998, 1999). However, critical levels of USBP inclusion in equine diets remain to be established. This study examines VFI, in vivo apparent digestibilities and nutritive values in ponies offered pelleted complete diets containing USBP at inclusion levels between 0 – 800 g/kg dry matter (DM).
