“…The pigs were provided with a daily dry matter intake of 1370 g. The feed was offered twice daily as a slurry (feed:water 1:2). Additionally, every pig was provided with 150 ml electrolyte solution (composition in g/1000 ml: 3.218 g Na, 0.195 g K, 0.036 g Mg and 0.1 g Ca) according to Hennig et al. (1989).…”

The aim of the present study was to investigate the precaecal and faecal digestibility of inulin (DP 10-12) and inulin/Enterococcus faecium mix, and the effects of these substances on nutrient digestibility and microbial gut flora. For the experiment four of eight male pigs were fitted with an end-to-end ileo-rectal anastomosis (IRA) with preserved ileo-caeco-colic valve. The residual pigs were used as intact partner (IN). The animals received 1.5 kg/day of a diet based on corn, wheat, barley and soybean meal, supplemented with either 8 x 10(9) CFU E. faecium/kg, 2% inulin or a mixture of both substances. The digestibility trial was carried out from weeks 4 to 8 after surgery. Precaecal digestibility of inulin was assessed to be 57%. The addition of E. faecium to the diet resulted in a similar precaecal digestibility of inulin of 55%. Supplementation of E. faecium, inulin, and a mixture of E. faecium and inulin did not affect precaecal and faecal nutrient digestibility with the exception of the precaecal digestibility of CF which increased when inulin alone was supplemented. Bacterial population in the digesta of IRA and IN pigs were not affected by the experimental diets except the concentration of bifidobacteria and lactobacilli. The supplementation of E. faecium to the diet significantly decreased the concentration of bifidobacteria and the population of lactobacilli inclined to decrease when IN pigs received the probiotic diet. The combination of E. faecium and inulin prevented a reduction of enterococci in faeces of IN pigs. The daily digesta excretion (DM) tended to decrease in IRA and IN pigs when inulin was supplemented. The results indicate that inulin (DP 10-12) in pig nutrition did partly react as a prebiotic as has been confirmed for humans. A combination of E. faecium and inulin improves the survival of the probiotic strain through the upper intestinal tract and allocates the synbiotic effect. Furthermore inulin might be able to show positive effects on precaecal and faecal microbial characteristics.

“…In the present experiment, these problems mentioned could be excluded since the animals were given supplementary electrolytes and vitamins: under conditions of restricted energy intake the weight gain and feed efficacy measured appeared within normal limits despite the absence of colic fermentation, and digestibility values obtained from the 4-9 and 12-17 weeks postsurgical measurements did not differ significantly, indicating no long-term digestive changes due to the surgical and postsurgical treatments. This implication is supported by the results of HENNIG et al (1986) andREDLICH et al (1997) who demonstrated that creating an ileo-rectal anastomosis did not result in a disturbed physiological state or histological changes in the duodenum or jejunum, the main sites of vitamin digestion, for at least 5 months, and it has also been shown that the end-to-end procedure was most beneficial for the structural integrity of the small intestine (REDLICH et al 1997). From the present findings it was obvious that the vitamin concentrations excreted via the chyme were distinctly higher in animals fitted with the ESV than in animals fitted with the EEV, indicating that the ESV procedure may permit some bacterial fermentation to take place.…”

Introduction There is a great need for better understanding of the intestinal bioavailability of B‐vitamins and the factors that influence it. In food products, however, nutrient content does not necessarily imply the proportion of nutrient content actually absorbed. Thus a variety of experimental approaches have been used for determining the intestinal bioavailability of food vitamins. They include measuring changes in tissue vitamin levels, urinary vitamin excretion and growth in response to known intakes of vitamin‐containing foods (e.g. Southern and Baker 1981; Gregory and Litherland 1986; Abad and Gregory 1987; Clifford et al. 1990; Swatilo et al. 1990; Yu and Kies 1993; Matte and Girard 1994). Potential limitations of those animal bioassays centre mainly on the role of the intestinal microflora and the extent of enhancement or inhibition of their vitamin synthesis by dietary components. The endogenous vitamin synthesis by the intestinal flora, with possible uptake in the distal part of the small and/or large intestine, is a complicating factor for nearly all B‐vitamins. The components of test diets that would stimulate the synthesis of B‐vitamins by intestinal microorganisms could therefore cause overestimation of dietary vitamin availability in conventional bioassays. Application of in‐vitro assays has also been reported for water‐soluble vitamins, but these are not recommended because of the limitations in extrapolation of the results to the situation in vivo (Holler et al. 1975; Seyoum and Selhub 1998). In principle, methods using stable isotopes will give the most reliable information concerning intestinal absorption, but their application is still limited, mainly because stable isotopes are not commercially available and specialized facilities and expertise are required. Ileo‐rectal anastomosis has been proposed as an alternative method for calculating the intestinal availability of nutrients (Herrmann et al. 1988; Green and Kiener 1989; Laplace et al. 1989; Hennig et al. 1990; Roth‐Maier et al. 1998). The most important advantage of ileo‐rectal anastomosis for measuring vitamin digestibility is the prevention of vitamin synthesis by the intestinal microflora and coprophagy, because the digesta can be collected quantitatively via the anus. In this respect two different techniques of ileo‐rectal anastomosis have been developed for pigs: the end‐to‐side (ESV) and end‐to‐end (EEV) ileo‐rectal anastomosis with preserved ileo‐caeco‐colic valve. Both methods have already been compared for their use as digestibility assays for the vitamins including thiamin, riboflavin and vitamin B6 (Roth‐Maier et al. 1998). The objective of the present study was to compare both the ESV and EEV techniques with regard to the digestibility values of folate, niacin and pantothenic acid, which has not been tested hitherto. In addition, in order to examine age‐ or time‐related effects on vitamin digestibility two different experimental periods after surgery were chosen for measurement.

Digestibility of amino acids in maize, wheat and barley meal, measured in pigs with ileo‐rectal anastomosis and isolation of the large intestine

Maize, soft wheat and barley diets were compiled to have similar crude fibre (CF) concentration by addition of purified cellulose. Protein-free diets, with purified cellulose included at 60 g kg-I dry matter (OM) (PFl) and 90 g kg-I DM (PIC?), were formulated. Each of four littermate, male pigs (22 kg liveweight) was surgically modified to create an ileo-rectal anastomosis with complete kolation of the large intestine. Diets were fed, and the ileal digesta, excreted via the anus, were collected. Endogenous amino acid output was higher after feeding PFZ than PFl. The choice of factor for correction of apparent digestibility (AD) to true digestibility (TO) was based upon CF intake of cereal diet. A D of most essential amino acids was greater in wheat than in maize or barley, although A D of lysine in barley (67.1%) was higher than in maize (56.8%) or wheat (63.4%). T D of most essential amino acids was higher for wheat and maize than for barley, although T D of lysine was similar for all cereals. Lysine and threonine were the most poorly digested essential amino acids in all cereals.
