Previous experiments indicated that several fibrous raw materials in dry sow diets failed to prevent excessive nutrient intake. Only a diet high in unmolassed sugar-beet pulp (SBP) limited voluntary intake to acceptable levels. SBP consists of mainly soluble fibre. It is known that some types of fibre can affect blood metabolites and hormone profiles, which might affect intake regulation. The effects on blood metabolites and insulin of a diet containing soluble or insoluble fibre were compared to a diet containing readily available carbohydrates.

It is well established that the intake and digestibility of roughages by ruminants is positively correlated with rate of passage (ARC, 1980), presumably to enable as complete a microbial degradation of the poorer roughages as possible. On the other hand hind gut fermenters such as horses have been thought to have adopted the alternative strategy of using a high rate of passage to ‘cream’ off the rapidly degradable material of poor quality roughages so as to maintain adequate nutrient intakes. Surprisingly, there are remarkably few actual comparisons between ruminants and hindgut fermenters in the literature. Traditionally dried roughages (hay) and cereal and ‘by-product concentrates’ have been used as horse feeds (grains, brans sugar beet pulp). Recently there has been more interest in the use of silages with horses (eg Smoulders and Hobiers, 1988). However the information as to the utilisation of silages by horses is limited.

AbstractThe number of days of data required to accurately estimate usual nutrient intake of children is not well established. This study aims to calculate the variability and the number of days required to estimate usual nutrient intake in children aged 13–32 months. This cross-sectional study, which is part of the BRISA Project in São Luís, Maranhão, Brazil, involved 231 children from April 2011 to January 2013. Socio-economic and demographic data were collected using a questionnaire, and 3 non-consecutive days of food consumption were collected using a 24-h dietary recall (24HDR) survey. Intrapersonal and interpersonal variability and variance ratio (VR) were obtained for each nutrient using the Multiple Source Method® program (version 1.0.1). The number of days (d) needed was calculated using the formula proposed by Black et al. for different correlation coefficients (r) (i.e. 0·7, 0·8 or 0·9). For the vast majority of nutrients, intrapersonal and interpersonal variability values of <1 were observed, with even smaller intrapersonal variabilities, resulting in low VR (<1). More days were needed to estimate intakes of soluble fibre (12), insoluble fibre (11), total fibre (10), vitamin C (9) and PUFA (7), while fewer days were needed for energy, carbohydrate, SFA, Ca, Fe, P and Zn (all had 2 d for r 0·9). However, most nutrients required one, two or three 24HDR for r 0·7, 0·8 or 0·9.

Experiments have demonstrated that inclusion of unmolassed sugar beet pulp (SBP) in diets for pigs gives rise to a major restriction in voluntary food intake in comparison with other high fibre materials (Brouns et al, 1991; Gill et al, 1992). The mechanisms for this are still not fully understood but appear to be related to the nature of the non-starch polysaccharides. SBP has a relatively high pectin content, so this experiment was designed to investigate whether another similar pectin containing material, citrus pulp (CIT), has similar intake regulating properties and whether these could be modified by treatment with a pectinase enzyme.The design was a split plot experiment with two dietary treatments. Each diet was manufactured, with and without enzyme, giving the following treatments: (1) Citrus pulp diet - no enzyme [CIT-]; 2) Citrus pulp diet - with enzyme [CIT + ]; 3) Sugarbeet pulp diet - no enzyme [SBP-]; 4) Sugarbeet pulp diet - with enzyme [SBP + ]. The experimental treatments were applied in a crossover design with 8 pigs receiving each diet both with and without enzyme.

The purpose of the work was to study the suitability of residue obtained during the methane fermentation process of sugar beet pulp for agricultural use in sugar beet plantations. Studies were performed with the sugar beet pulp fermentation residue and sugar beets (Beta vulgaris cv. Fighter) harvested from experimental plots. It was found that the by-product of sugar beet pulp digestion may be utilized in agriculture taking into account its chemical and microbiological standards. The nutrients in digestion residue were as assimilable for sugar beet plants as the nutrients in mineral fertilizers. The evaluation of technological parameters of sugar beet harvested from experimental plots based on standard technological criteria showed that irrespective of fertilization treatment, the raw material obtained met most of the requirements and can be used as a stock material for sugar production.

SUMMARY1. The effects of 0·9 to 1·0 kg molassed sugar beet pulp cubes, supplemented with minerals and vitamins and with either 0, 3·0 and 7·8% urea, on the voluntary intake of oat straw (either 2·0 or 3·0% crude protein) were measured in two experiments with 250 to 300 kg British Friesian steers.2. Straw intake was increased by a maximum of about 20% when a total of about 165 g crude protein was supplied by the urea-containing sugar beet products.3. In one digestibility trial conducted with 385 kg steers, the inclusion in sugar beet pulp of urea equivalent to 89 g and 169 g crude protein/day comparably and significantly increased the digestibility of dry matter and crude fibre.

Twenty-eight lamb ewes (44 + 0.45 kg live weight) were used to study the effect of type and level of supplementation on voluntary intake of barley straw, treated with 30 g/kg of anhydrous ammonia (TS) or untreated (US) but given with urea to ensure the same nitrogen content as TS (18 g/kg DM). Each type of straw was offered ad libitum, supplemented with grass hay, rolled barley and sugar beet pulp at rates of 150, 300, 4 50 and 600 g/d, in 6 Latin Squares (4 x 4). In addition, another 2 sheep received each straw alone during the same periods. Supplements were totally consumed, except hay, which was refused in 10 - 13 and 28 - 34 per cent for US and TS, respectively.Daily dry matter intake (DMI) of US (OMD = 0.423) and TS (OMD = 0.515) offer as sole feed were 511 ± 29.1 and 858 ± 45.2 g. As show TABLE 1, US was consumed at rates of 527, 576 and 568 g DM when supplemented with 150 g of hay, barley and sugar beet pulp, and no significant differences were found with further levels of supplementation. DMI of TS decreased linearly from 850 to 618 g/d (r = 0.75) and from 717 to 518 g/d (r = 0.63) when the level of barley and sugar beet pulp increased from 150 to 600 g/d. Substitution rates were estimated to be 0.31 and 0.27 for barley and sugar beet pulp, respectively. Decrease in TS intake when supplemented since 150 to 600 g/d of hay (720 to 605 g, respectively) were found not significative.

Abstract Utilizing different dietary fiber sources has been studied in piglets to help mitigate post-weaning diarrhea and improve post-weaning performance. An experiment was conducted to investigate the effect of adding sugar beet pulp or a stimbiotic (Signis; AB Vista) on nursery pig performance. Barrows (n = 216; average initial BW = 5.1kg) were randomly allotted to one of three dietary treatments and fed a 4 phase feeding program; 1) Control (Con), Insoluble/Soluble fibre ratio (I/S), P1; 4.47, P2; 5.84, P3; 5.82, P4; 7.08. 2) High Soluble (HS) with sugar beet pulp added at 5% (P1 and P2) and 2.5% (P3 and P4) giving the following I/S ratio; P1; 2.63, P2; 2.91, P3; 5.02 and P4; 5.42. 3) Control plus stimbiotic added at 100 g/t (SIG). Pen weight and feed disappearance were recorded weekly to calculate ADG, ADFI, and G:F. Fecal score was visually ranked by pen daily from wean to 35 days. Blanket water medications were not provided. Instead, individual pigs that needed treatment were identified and injected with individual antibiotic interventions, and the number of interventions per pig was recorded. Performance data were submitted to ANOVA using JMP with mean separation by Tukey test and a contingency analysis was used to compare antibiotic injections. At day 14, pigs had a Rotavirus A and B challenge. Addition of HS or SIG reduced (P &lt; 0.05) individual antibiotic treatments by 56 and 32% compared to the CON, respectively. No differences were observed in scour scores or overall ADG. Overall intake was greater (P &lt; 0.01) in HS (0.560 kg) than CON (0.491 kg) or SIG (0.492 kg). Pigs fed SIG (0.671) had a better (P = 0.011) G:F over SBP (0.602), with CON (0.649) being intermediate. In conclusion, HS increased intake where stimbiotic improved feed efficiency, and both decreased antibiotic treatments.
