Nutrient Digestion

An experiment was carried out to examine the effects of supplementing diets for weanling pigs with oligosaccharides and LAC on nutrient digestion and bacterial populations and metabolites in the small intestine. Twelve barrows, weaned at 28 d, were fitted with a simple T-cannula at the distal ileum. The BW of the pigs at weaning and at the conclusion of the experiment were 9.1 and 13.8 kg, respectively. The pigs were fed four diets based on barley, wheat and soybean meal according to a two-period change-over design. The diets were formulated to contain 18% CP. Transgalactosylated oligosaccharides (0.2%), GUO (0.2%) and LAC (1%, 4-O-β-D-galactopyranosyl-D-sorbitol) were included at the expense of corn starch. Supplementation with oligosaccharides or LAC had little effect on the apparent ileal digestibilities of AA and monosaccharides. Supplementation of diets with oligosaccharides or LAC did not affect (P > 0.05) the monosaccharide concentrations in ileal digesta except for galactose which was higher (P < 0.05) in digesta from pigs fed the diet supplemented with LAC. The daily ileal output of monosaccharides, pH, ammonia and VFA concentrations, bacterial populations in ileal digesta and incidence of diarrhea were not affected (P > 0.05). Therefore, the supplementation of diets for weanling pigs (9.1–13.8 kg) with oligosaccharides or LAC at these levels does not affect nutrient digestibilities and bacterial populations in the small intestine.

Cereal Grain

The biological availability of biotin in canola meal (CM), cereal grain, cereal grain plus CM, and soybean meal (SBM) was estimated, using 140 pigs in the 10- to 20-kg weight range. In exp. I, pigs (six/treatment) were individually housed and fed a basal casein-cornstarch diet with 0, 50, 100, 150, 200 or 250 μg d-biotin kg−1 to generate data for a dose-response curve based on plasma biotin concentration. Other pigs were fed CM, SBM or soyprotein isolate (SPI) included in the diet. In exp. II, pigs were housed in pairs and four pairs were fed diets based on cereal grain or cereal grain plus CM. Results (exp. I) showed a higher correlation between daily biotin intake and plasma biotin (r = 0.835, P < 0.01) than on growth rate (r = 0.627, P < 0.05). The regression for plasma biotin (Y) on biotin intake (X) computed from the linear portion of the curve (i.e., 0-200 μg added biotin kg−1) was[Formula: see text]Biotin bioavailability in various feedstuffs was highest for corn (101.2%), followed by SBM (85.5%), CM (70.9%), and wheat (33.3%), triticale (25.9%), sorghum (25.1%) and barley (24.0%).

Copper Supplementation

The digestive utilization of minerals in Cu- and phytase-supplemented diets by weanling pigs was investigated in an experiment with a 3 × 2 factorial arrangement of treatments. Three levels of Cu (0, 60 and 120 mg kg−1 as CuSO4∙5H2O) and two levels of phytase activity (0 and 1500 units kg−1) were added to a corn-soybean meal basal diet. Seventy-two pigs (gilts:bar-rows, 1:1) with an average initial weight of 9.7 kg received the six diets for 21 d, after which 36 of the pigs were used in an 8-d mineral balance study. Phytase supplementation of diets increased serum P, Zn and Mg concentrations but reduced serum Cu concentration. The addition of Cu to the diets produced serum concentrations of minerals similar to Cu-unsupplemented diets. Absorption and retention of Ca and P were both slightly increased in pigs fed the phytase-supplemented diets compared with pigs fed diets that did not contain phytase. Addition of phytase to the diet that was not supplemented with Cu doubled (P < 0.1) Cu retention. Copper supplementation of diets did not affect absorption and retention of Ca, P, Zn, and Mg but increased absorption and retention of Cu and Mn. Results indicate that addition of phytase to P-supplemented and Cu-unsupplemented diets improves digestive utilization of P and Cu. Key words: Pigs, phytate, copper, phytase, minerals

Abstract An experiment was conducted to determine effects of isoquinoline alkaloids (IQ) on growth performance and blood characteristics of weanling pigs fed corn-soybean meal-based diets. A total of 160 pigs (6.33 ± 0.61 kg) were allotted to 4 corn-soybean meal-based treatments, with 4 pigs per pen and 10 replicate pens per treatment. A 3-phase feeding program was used with d 0 to 8 as phase 1, d 8 to 21 as phase 2, and d 21 to 34 as phase 3. Within each phase, the 4 diets were identical except for the inclusion of IQ in the feed: 0, 90, 180, or 360 mg IQ/kg complete feed. Pig weights and the feed left in the feeders were recorded on the last d of each phase to calculate average daily gain and average gain:feed ratio. A blood sample was collected from 1 pig per pen on d 8, 21, and 34. Data were analyzed by linear and quadratic contrasts using the Proc MIXED of SAS with coefficients for unequally spaced treatments being generated from Proc IML. Results indicated that there were no differences among treatments in growth performance over the entire experimental period (Table 1). A quadratic increase (P < 0.05) of total protein in plasma was observed in phase 1, with the highest value in plasma of pigs fed the 180 mg/kg IQ diet, and there was a tendency for plasma urea N to increase in phases 2 and 3 (linear; P = 0.07) if IQ was added to the diet. In conclusion, although IQ supplementation did not effect overall growth performance, results indicate that absorption of amino acids was likely improved by inclusion of IQ in the diets as evidenced by the increased plasma urea nitrogen and increased total protein in plasma.

Similar Growth

Three groups, each of five pigs, of initial age 5–6 weeks and initial weight 12 kg, were placed on each of three wheat-soybean-meal-based diets of 18% crude protein content. The diets contained either (a) no antibiotic, (b) 110 mg/kg chlortetracycline hydrochloride, 110 mg/kg sulfamethazine and 55 mg/kg penicillin, or (c) diet (b) minus penicillin. Both antibiotic treatments produced a similar growth response of approximately 12%, which resulted partly from an increased feed intake and partly from an improved efficiency of feed utilization.
