Methodological Considerations

Abstract It is of important methodological considerations to understand how the small intestine would respond to feeding of a series of assay diets deficient in gradient levels of phosphorus (Pi) associated with corn in growing pigs by the regression analysis technique (TRAT). A total of 48 barrows, with an average initial BW 32 kg, were randomly assigned to 6 grower pig diets and were fed close to ad libitum for 10 d, with 8-d adaptation and 2-d collection fecal samples, according to a randomized complete block design. Six cornstarch-based diets, containing 6 levels of Pi at 1.3, 1.9, 2.0, 3.6, 3.4 and 4.0 g/kg DMI, were formulated from corn. The gut permeability marker of D-mannitol was fed 0.30 g/kg BW at 4 h, prior to be sacrificed for sampling. ADG and the apparent ileal DM digestibility were linearly affected (P < 0.05); however, the ADFI, feed conversion ratio, the apparent fecal DM digestibility, transcellular gut permeability and the jejunal alkaline phosphatase kinetics were not affected (P > 0.05) by the increasing dietary levels of corn inclusion. There were linear relationships (P < 0.05), expressed as g/kg DMI, between the apparent ileal and fecal digestible Pi and the total intake of dietary Pi, suggesting that true ileal and fecal Pi digestibility (33.3±4.7 vs. 52.7±3.8%); and the endogenous Pi outputs (0.37±0.12 vs. 0.60±0.09, g/kg DMI) associated with corn could be estimated by the TRAT. Our results have shown that the intestinal physiological functions were not affected in the grower pigs fed on a series of test diets that were deficient in gradient levels of multiple assay nutrients, including macro-minerals, crude protein and amino acids supplied from the testing corn, for a period of 10 d, in the determination of corn-specific true digestibility and the endogenous outputs of Pi by the TRAT.

Abstract Dietary magnesium (Mg) is essential to bone mineralization. Supplemental Mg is typically not considered in commercial swine diets by assuming high bioavailability of Mg from bulky feed ingredients such as corn grain. The objectives of this study were to determine true ileal and fecal digestibility and the endogenous losses of Mg associated with corn in growing pigs by the regression analysis technique. A total of 48 barrows, with an average initial body weight (BW) 32 kg, were randomly assigned to 6 grower pig diets and were fed close to ad libitum for 10 d, with 8-d adaptation and 2-d collection fecal and the terminal ileal digesta samples, according to a randomized complete block design. Six cornstarch-based diets, containing 6 levels of Mg at 0.22, 0.32, 0.38, 0.51, 0.71 and 0.79 g/kg dry matter intake (DMI) of diets, were formulated from corn. There were linear relationships (P < 0.05), expressed as g/kg DMI, between the ileal and fecal outputs of Mg and the total intake of dietary Mg, suggesting that true ileal and fecal Mg indigestibility values (94.8±12.5 vs. 89.2±17.7%); and the ileal and fecal endogenous Mg outputs (0.16±0.02 vs. 0.21±0.11, g/kg DMI of diets) associated with corn could be estimated by the regression analysis. Our results have shown that Mg associated with conventional corn grain was very poorly digested and the gastrointestinal endogenous fecal loss of Mg was significant in the grower pig. Thus, Mg bioavailability in feeds for pigs should be assessed and supplemental of Mg may be warranted in swine diet formulation.

Abstract There is limited knowledge regarding trace mineral bioavailability in trace mineral supplements and common feed ingredients and trace mineral endogenous losses in pigs. The objectives of this study were to investigate intestinal responses and to determine true total tract trace mineral digestibility and the endogenous losses of trace minerals associated with corn and SBM based diets in weanling pigs by the regression analysis. Twenty-four crossbred barrows, with an average initial BW of 14 kg, were randomly assigned to 4 weanling pig diets with inclusion of titanium dioxide (0.30%) and a commercial trace mineral-vitamin premix at 0.125, 0.250, 0.375 and 0.500%, respectively, to result in 4 graded dietary levels of Cu, Zn, Fe, Mn and Se. The pigs were fed close to ad libitum for 11 d according to a randomized complete block design. The dietary inclusion did not affect (P > 0.05) growth performances, ileal and fecal DM digestibility, D-mannitol gut permeability and jejunal alkaline phosphatase kinetics. With the regression analysis, true total tract Cu, Zn, Fe, Mn and Se digestibility values (±SE; n = 23 or 24; P < 0.05) in the trace mineral-vitamin premix were determined to be 137.3±27.9, 40.5±15.4, 66.2±24.6, 94.3±21.6 and 96.6±2.8% vs. the corresponding values in the four weanling pig diets for Cu at 137.4±3.2, Zn at 40.4±3.1, Fe at 66.2±3.0, Mn at 94.2±3.8and Se at 96.2±0.8%, respectively. The total tract endogenous Cu, Zn, Fe, Mn and Se outputs (±SE)associated with the weanling pig diets were also determined (23.4±0.6, 9.2±2.7, 37.2±3.5, 19.4±1.0 and 0.07±0.003 mg/kg DMI diets; n = 23 or 24;P < 0.05). Our results have shown that the intestinal physiological functions and performances were not significantly affected in the weanling pigs fed on the diets with reduced gradient levels of a trace mineral-vitamin premix. Total tract true digestible trace mineral supply should be considered in swine diet formulation.

SUMMARYTwo experiments of randomized block design were carried out at the Agricultural Research Institute of Northern Ireland in 1991/92 involving groups of 20 pigs fed ad libitum from single-space feeders with built-in water supply from 37 kg to slaughter at 91 kg liveweight.Treatments were replicated 16 and 6 times respectively in Experiments 1 and 2. In the first experiment, one feeder perpen was compared with two feeders per pen positioned side by side. Two feeders increased feed intake (P < 0·05) but had no significant effects on growth rate or feed conversion. With two feeders, the total time that feeders were occupied and the number of visits to feeders were both increased, while the number of enforced withdrawals from feeders and the amount of queuing were both decreased compared with the single feeder. In the second experiment, placing two feeders 2 m or more apart instead of side by side had no significant effects on feed intake or growth rate but improved feed conversion efficiency by 4%. This improvement was associated with fewer and longer visits to feeders but no difference in enforced withdrawals or queuing. In both experiments all treatments showed broadly similar patterns of diurnal feeding behaviour with two peaks of activity daily, a smaller peak pre-midday and a larger one in the afternoon. This pattern was influenced more by number of visits to feeders than by the mean duration of each visit. It is recommended that two single-space feeders are used in pens of 20 finishing pigs when non-pelleted diets are offered ad libitum and that feeders are sited some distance apart, not side by side.

ABSTRACT: The purpose of this study was to assess the levels of available phosphorus (AP) in the diet of growing pigs selected for lean deposition on the hematological, biochemical, and bone performance parameters. A total of 64 commercial hybrid pigs (32 castrated males and 32 females; mean initial weight: 23.31±2.4kg; age: 55-90 days) were used. Animals were distributed into a randomized block design with four treatments, eight replicates, and two animals (one male and one female) per experimental unit. The treatments consisted of a basal diet and another three diets, which were obtained by supplementing the basal diet with dicalcium phosphate replacing the inert phosphate, resulting in four diets with 0.100, 0.180, 0.260, and 0.340% of available phosphorus. The levels of available phosphorus quadratically influenced the daily weight gain, feed consumption, and feed conversion, which increased up to the estimated levels 0.331; 0.330, and 0.302% of available phosphorus. Levels of phosphorus showed no influence on the hematological parameters, which remained within the reference values. Levels of available phosphorus increased linearly the ash and phosphorus contents in the metacarpal bone and decreased linearly the alkaline phosphatase activity. Levels of available phosphorus (0.331 and 0.302%, corresponding to a daily intake of 5.73 and 5.18g d-1) provided respectively the best results for weight gain and feed conversion in pigs with high genetic potential, without change in hematological parameters.

It was intended with the present work to verify the effect of phytase on the performance, bone mineralization and content of plasma urea of swine. 80 swine (30 ± 3.1 kg/LW), crossbred (LD x LW) males and females, allocated to a randomized block design (RBD) with four treatments and five replicates. The treatments consisted of a growing swine diet on the basis of corn, soybean meal and defatted rice bran (DRB) supplemented with four levels of phytase (0, 400, 800 and 1200 FTU/kg) The diet was formulated to meet the requirements of growing swine except for available calcium and phosphorus, the levels of which were 0.64 and 0.25%, respectively. The enzyme phytase utilized was Natuphos 5000. Over the experimental period every eight days, blood of two animals per block was collected through a puncture in the sinus orbital, to determine the plasma urea content. At the final of the experimental period, two animals were slaughtered for collection of the metacarpus bone, aiming to verify the mineral content. The variables analyzed were: daily average weight gain (DAWG), daily average ration consumption (DARC), feed conversion (FC), content of plasma urea, content of ashes, calcium, phosphorus, manganese, zinc and magnesium in the bone. The phytase levels provided a linear improvement (P<0.05) on feed conversion and a quadratic effect on swine's plasma urea content. Phytase promoted a linear increase (P<0.05) on the content of calcium and phosphorus in the swine's metacarpus bone. The level of 750 FTU/kg provided the lowest plasma urea content. It is concluded that the use of the enzyme phytase in growing swine diets improved feed conversion, decreased the plasma urea content and increased the contents of calcium and phosphorus in the bone.

SUMMARYDried poultry manure, produced locally by sterilization and drying, was evaluated as an addition to a conventional diet, at levels of 10, 20 and 30%, for growing pigs from 23 to 85 kg live weight. The 32 pigs remained healthy and the dried manure had no apparent adverse effect on the carcasses.There were significant linear relationships between the amount of manure added to the conventional diet and growth rate, feed conversion efficiency and certain carcass characteristics. For every 10% addition of manure, growth was reduced by 0·02 kg/day, feed conversion efficiency by 0·25 units and killing-out percentage by 0·96. The dried manure contained about 30% crude protein and was a rich source of minerals.
