“…After the temporal anorexia and growth check observed during the first days postweaning, the adaptive phase is characterized by a gradual increase ofthe ADFI and ADG (Bikker et al, 2004;DeRouchey et al, 2004;Zier et al, 2004;Zhao et al, 2007;Piva et al, 2008). However, there is a time difference between the weaning-associated diarrheal episodes and the growth check.…”

The present study investigated the effect of 3 different durations of feeding a diet supplemented with defatted bovine colostrum (Col) on growth performance and sanitary status of the weaned piglet. At 28 d of age, piglets were weaned and fed 1 of the 2 following diets: a control (Ctrl) starter diet or a starter diet supplemented with Col. Two experiments were conducted. In Exp. 1, 310 piglets (12 pens consisting of 10 piglets/pen and 10 pens consisting of 19 piglets/pen) were allocated to 1 of the 2 dietary treatments for 12 d. In Exp. 2, 522 piglets (18 pens consisting of 10 piglets/pen and 18 pens consisting of 19 piglets/pen) were allocated to 1 of the following 3 dietary treatments: fed the Ctrl diet from d 1 to 12 (Ctrl), Col diet from d 1 to 4 and then the Ctrl diet up to d 12 (Col-4d), or the Col diet from d 1 to 6 and then the Ctrl diet up to d 12 (Col-6d). For both experiments, a commercial second-phase diet was fed to piglets from d 12 to 46. Feed intake, growth performance, and cleanliness of floor and hindquarters of animals were investigated during the first 7 wk postweaning. In Exp. 1, from d 0 to 12, ADFI, ADG, and G:F were 16 (P = 0.004), 23 (P < 0.001), and 5% (P = 0.069) greater, respectively, in Col piglets compared with Ctrl piglets. Thereafter, ADFI and ADG were 7 (P < 0.001) and 9% (P < 0.001) greater, respectively, in Col piglets than Ctrl piglets (d 12 to 46). On d 12 after weaning, piglets fed the Col diet had more normal feces (+13%) and less soft or liquid feces (-9 and -4%, respectively) than piglets fed the Ctrl diet (P = 0.06). Compared with Ctrl piglets, feeding the Col diet led to more days with normal feces for the floor cleanliness (+22%; P < 0.001) from d 7 to 11. In Exp. 2, compared with Ctrl piglets, ADFI, ADG, and G:F were 8, 23, and 13% greater (P < 0.05) in Col-6d piglets from d 0 to 9, whereas values for Col-4d piglets were intermediate and did not differ from the values of the other dietary treatments. On d 9 after weaning, piglets fed the Col-4d or the Col-6d diet had more normal feces (+6 and +4%, respectively) and less liquid feces (-4 and -3%, respectively) than piglets fed the Ctrl diet (P = 0.08). No long lasting effects were observed thereafter. In conclusion, there was a reduction of weaning-induced growth check and diarrheal episodes in weaned piglets fed the Col diet. The beneficial effects of the bovine colostrum were observed beyond the period of treatment when the supplementation covered the first 6 d postweaning, which corresponded to the acute phase of postweaning digestive disturbances.

“…As expected, data from both experiments demonstrated that meal diets have a slightly greater concentration of total bacteria counts than pelleted diets, indicating that meal diets have a greater potential of containing pathogenic bacteria. Spray-dried animal plasma, fish meal, and soybean meal are ingredient sources that have potential for greater bacterial concentrations (Kume et al, 1982;DeRouchey et al, 2004;Maciorowski et al, 2007). Fish meal has even been shown to be a source of Salmonella (Morris et al, 1970), which can reduce the growth performance of weanling pigs.…”

“…Effects of bacteria from nonpelleted ingredients on pig growth performance are not well understood. Previous research demonstrated improvement in growth performance when nursery pigs were fed diets containing irradiated SDAP (DeRouchey et al, 2003a(DeRouchey et al, ,b, 2004, suggesting that ingredient bacterial concentrations may affect growth performance in meal diets. DeRouchey et al (2003a) also demonstrated that nursery pigs fed diets containing irradiated soybean meal had increased ADG, ADFI, and G:F, and pigs fed diets containing irradiated fish meal tended to have improved G:F. Therefore, the objectives of these experiments were to determine the effects of nonirradiated or irradiated SDAP fed in either meal or pellet form, and to evaluate the effects of irradiated protein sources (SDAP, soybean meal, and fish meal) in the diet, fed in either meal or pelleted form, on nursery pig performance.…”

Two experiments were conducted to evaluate the effects of irradiated ingredients in meal and pelleted diets on nursery pig performance. In Exp. 1, a total of 192 pigs (initial BW, 6.0 kg) were used in a 25-d experiment. Pigs were blocked by BW and randomly allotted in a 2 x 2 factorial arrangement of treatments with main effects of diet form (meal or pellet) and either irradiated (11.92 kGy) or nonirradiated spray-dried animal plasma (SDAP). Irradiated SDAP had less total bacterial amounts than nonirradiated SDAP, and pelleted diets also had less bacterial amounts than diets in meal form. However, the complete diets with and without irradiated SDAP had similar bacterial concentrations. There was a diet form x SDAP irradiation interaction (P < 0.05) for ADG from d 0 to 11 and d 0 to 25. Pigs fed irradiated SDAP in meal form had increased ADG compared with pigs fed the nonirradiated meal diet, with no change in ADG of pigs fed pelleted diets. In addition, from d 0 to 11, pigs fed irradiated SDAP or pelleted diets had greater G:F (P < 0.01) compared with pigs fed regular SDAP and meal diets, respectively. In Exp. 2, a total of 350 pigs (initial BW, 4.9 kg) were used in a 22-d experiment to determine the effects of feeding irradiated protein sources (SDAP, soybean meal, fish meal, or all 3) in meal and pellet diets on pig performance. Pigs were blocked by BW and randomly allotted to 1 of 10 treatments consisting of a single diet formulation fed in either meal or pellet form containing either no irradiated protein sources or irradiated SDAP, soybean meal, fish meal, or all 3 irradiated protein sources (10.20 kGy). Irradiated SDAP, soybean meal, and fish meal tended to have reduced total bacterial concentrations compared with nonirradiated plasma, and pelleted diets had reduced bacterial concentrations compared with diets in meal form. No irradiation x diet form interactions (P > 0.16) were observed. From d 0 to 11, pigs fed diets containing irradiated protein sources had greater (P < 0.03) G:F compared with pigs fed the control diets, with no difference in ADG or ADFI. From d 0 to 11, and overall (d 0 to 22), pigs fed pellet diets had greater G:F (P < 0.01) compared with pigs fed meal diets, with no difference in ADG and ADFI. These studies indicate that both irradiation and pelleting are manufacturing processes that can reduce bacteria concentrations in feed ingredients and diets. Irradiated SDAP, soybean meal, and fish meal improved G:F compared with control diets containing nonirradiated ingredients. Furthermore, pigs fed pelleted diets had increased G:F compared with pigs fed meal diets.

“…Gamma irradiation of diet was evaluated in pig (DeRouchey et al, 2003a(DeRouchey et al, , 2003b(DeRouchey et al, , 2004Groesbeck et al, 2006) and in chicken (Gharaghani et al, 2008;Chamani et al, 2009). All results of animal feeding studies reported, more or less, an improved growth performance.…”
