“…Texture of the feed interfered with feed intake in pigs (Sola-Oriol et al, 2009) and chickens (Picard et al, 2000). Interestingly, dietary moisture content has an impact on feed intake and nutrient utilization of poultry (Scott, 2002) and weaning piglets (Schellingerhout, 2002) and is also important for physical quality of pellets (Gilpin et al, 2002, Lundblad et al, 2011, Moritz et al, 2001. It can therefore be hypothesized that feed moisture content can be used as a mean to adjust pellet quality of feed for Atlantic salmon.…”

Feed pellets in modern aquaculture must be of high physical quality to withstand mechanical impacts. However, physical quality of feed has been shown to affect nutritional responses. In the present study, different moisture contents were used to modify physical feed qualities.Effects of dietary moisture content on physical feed quality, feed intake, nutrient digestibility and growth performance in Atlantic salmon were investigated. Different drying times of four commercial-like extruded diets resulted in in dry matter contents of 95.9%, 94.1%, 92.3%, 90.8%. A fifth diet containing 70% dry matter was made

“…This is not surprising, not only because growth performance is not usually affected by extruding or expanding the major grain ingredient or complete diet in young pigs (Noland et al, 1976;Ginste and De Schrijver, 1998;Hongtrakul et al, 1998;Lundblad et al, 2011), but because the percentage of the processed corn in the experimental diet (12.5%) was lower than those used in these studies. It thus seems apparent that use of the thermally processed corn at a low percentage in a milk product-cornsoy-based pig starter diet has no effect on growth performance although energy and N digestibilities are increased following the thermal processing (Sauer et al, 1990;Lv et al, 2006;Lundblad et al, 2012).…”

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.

“…In contrast, the use of a pelleted diet during the nursery phase has been reported by two authors to improve the FC with no effect on DWG and DFI. LUNDBLAD et al (2011) tested various heat processing treatments (pelleting at 47°C, pelleting at 90°C, expansion at 105°C, and extrusion at 120°C, 4.0mm pellet size) for a wheat meal, soybean meal, and fish flour-based diet for weaning pigs and observed a better FC, with no effect on DFI or DWG compared to the corresponding meal diet. The authors attributed this improvement to a decreased FW.…”

“…Nutritionally, in addition to the rate of feed consumption, the digestibility of the diet is one of the most important factors affecting zootechnical performance (MAHAN & LEPINE, 1991). The heat processing of diets, such as pelleting, expansion, and extrusion procedures, can increase digestibility (LUNDBLAD et al, 2011).…”

Physical form effect of the pre-starter diet supplied during the post-weaning period from 21 to 41 days of age on diet digestibility and animal performance in terms of zootechnical performances of light-weight (5.82kg) and heavy-weight weaning piglets (6.32kg) was evaluated, as well as the residual effects of the treatments until slaughter. Forty-eight female pigs at 21 days of age were evaluated. The experimental design was completely randomized in a 2x2 factorial scheme (meal/pelleted diet vs. light-weight/heavy-weight piglets), with six replicates for the nursery phase and 12 replicates for the growing-finishing phases. Animals received the experimental diet from 21 to 41 days of age. Data were analyzed with ANOVA, setting the significance in 5%. Feeding with the pelleted diet resulted in a 39% greater daily weight gain and a 28% greater feed conversion rate for piglets from weaning to 40 days of age. Pelleting also resulted in a decrease in feed wastage during the first week after weaning (9.15% for meal diet vs. 1.68% for pelleted diet) and; consequently, the results showed an increase in feed consumption. Digestible energy of the pelleted diet (3,626kcal kg-1) was greater than that of the meal diet (3,424kcal kg-1). The physical form improved the performance of weaning pigs and the digestibility of the pre-starter diet, but there wasn't residual effect of the physical form and the weight of a piglet at weaning on live weight at slaughter.
