“…In the present study, extrusion of maize and sorghum did not improve the ileal digestibilities of amino acids, with the exception that the digestibility of Met in sorghum was improved (P<0.05) in EW pigs as compared with ground maize or sorghum. This result is in partial agreement with previous studies for maize (Herkelman et al, 1990) and sorghum (Noland et al, 1976). Herkelman et al (1990) reported that extrusion improved energy utilisation but did not affect utilisation of lysine or N in maize by growing pigs.…”

“…Herkelman et al (1990) reported that extrusion improved energy utilisation but did not affect utilisation of lysine or N in maize by growing pigs. Noland (1976) also reported that extrusion improved energy digestibility of high tannin sorghum grain when fed to nursery pigs. It seemed that the extrusion temperature for maize and sorghum was moderate in this study.…”

“…One of the differences for conducting the experiments between the present study and that of Richert et al (1992) was diet forms (pellet vs meal), which can affect the performance of pigs. However, Noland (1976) reported that extruding sorghum grain resulted in no improvement in rate of gain or feed efficiency in young pigs.…”

“…Likewise, extrusion of cereal grain increases the gelatinization and surface area of starch granules (Bjorck, 1985), which improves nutrient digestibility (Noland et al, 1976;Skoch et al, 1983), and growth performance (Richert et al, 1992). However, Herkelman et al (1990) reported that extrusion of maize improved energy utilisation but not utilisation of lysine or N by pigs.…”

Two experiments were conducted to compare apparent ileal digestibilities and growth performance in pigs fed ground and extruded maize and sorghum. In Experiment 1, for digestibility, 24 early-weaned pigs (14 d old and 3.2 kg BW; EW) were given a terminal ileum exteriorization, and another 24 conventionally-weaned (CW) piglets (21 d old and 6.3 kg BW) were fitted with simple T-cannulae. An additional 8 piglets were employed for correction of endogenous amino acid excretions. Dietary treatments consisted of six differently processed maize and sorghum diets: 1. maize 900 )Ltm, 2. maize 400 |Um, 3. extruded maize, 4. sorghum 900 [im, 5. sorghum 400 |im, and 6. extruded sorghum. In Experiment 2, 150 piglets (21 d of age and 6.4 kg BW) were allotted to the same dietary treatments and used in a 33-d feeding trial.Reduced particle sizes of the grains from 900 to 400 |Lim tended to improve the apparent ileal digestibilities (AID) of Thr, Val, Leu, and Lys in maize and Thr, Val, and Leu in sorghum for EW, but not for CW piglets. The AID of essential amino acids were higher (P<0.05) in CW than in EW piglets. In true ileal digestibilities (TID) of essential amino acids in tested grains, there was a similar trend with the AID of essential amino acids, with the exception of improvement by 10.7% in EW, and in TID of essential amino acids, respectively, between weaning ages. Extrusion of maize and sorghum did not improve the ileal digestibilities of amino acids, but the digestibility of Met in sorghum was improved (P<0.05) in EW pigs as compared with ground maize and sorghum. Between maize and sorghum, the ileal digestibility of amino acids was similar. During the overall period (d 0 to 33), diets with extruded maize and sorghum reduced ADFI (PO.05) and improved gain/feed (PO.05) by 3%o compared with diets with the ground grains.In conclusion, the ileal digestibility of amino acids in the grains was considerably affected by weaning ages of piglets, while ileal digestibility of amino acids and growth of pigs was not affected by reductions in particle sizes of maize and sorghum from 900 to 400 mm in complex weaner diets.

“…The thermal processing shears and gelatinizes starch to increase the energy digestibility (Noland et al, 1976;Herkelman et al, 1990;Li et al, 2010), denatures and shears protein usually resulting in an increase of N digestibility (Sauer et al, 1990;Lundblad et al, 2012), and reduces the moisture content of the processed ingredient or diet (Hancock and Behnke, 2001). Moreover, thermal processing of the grain or whole diet usually increases the feed conversion efficiency, which can result in an increase in weight gain (Wondra et al, 1995a,b) or no effect on growth performance (Noland et al, 1976;Ginste and De Schrijver, 1998;Lundblad et al, 2012) of nursery as well as growingfinishing pigs. Sauer et al (1990) have reported that extruding a cereal-based nursery diet was more effective than pelleting in increasing weight gain and feed conversion efficiency of the pigs.…”

The aim of the present study was to investigate the effects of partial substitution of an extruded or extruded-pelleted corn product for unprocessed corn of the starter diet on growth performance and incidence of diarrhea in weanling pigs. Seventy-two 21-day-old weanling pigs were allotted to 24 pens and provided ad libitum with one of the four experimental diets for 3 wk in two serial feeding trials during summer beginning from late June. The treatments were a milk product-soy-corn-based control diet containing 25% unprocessed corn and the other three diets only substituted with 12.5% extruded corn Suprex ® , Optigrain ® , an extruded mixture of wheat, rye and durum, or extruded-pelleted corn for an equal percentage of unprocessed corn of the control diet. All diets were supplemented with 100 ppm sulfathiazone, 50 ppm penicillin, and 100 ppm chlortetracycline for preventive medication. The initial and final weights as well as gain : feed were less in the second trial than in the first one (P<0.05). However, effects of the dietary treatments were not detected in any of the performance variables including final weight, ADG, ADFI, and gain : feed, nor were there any interactions between the trial and dietary treatment. In addition, almost all pigs exhibited normal firm feces in both trials and therefore there was no main effect in the fecal consistency score. Results suggest that partial substitution of the thermally processed corn for unprocessed corn of the milk product-corn-soy-based and medicated starter diet has no effect on growth performance or incidence of diarrhea in weanling pigs.
