“…In the study of Wu et al (2004), pre-pelleted whole wheat generated substantial increases in nutrient digestibility without tangibly increasing gizzard weight. From the tested hypothesis of the present study, whole and hard maize cultivars increased gizzard weight, which was consistent with the results from previous whole grain studies (Svihus et al, 2004a;Singh et al, 2014a;Singh et al, 2015;Moss et al, 2018). Amerah et al (2009) reported that feeding hard wheat cultivars resulted in relatively heavier gizzard weight in comparison to soft wheat.…”

“…In the current trial, whole maize feeding had no influence on the ileal nitrogen and starch digestibility, in agreement with the findings of Singh et al (2014b). In contrast, several previous studies with whole grain have reported improvements in the ileal and starch digestibility (Svihus et al, 2004a;Wu et al, 2004;Singh et al, 2015). Interestingly, in the present study, ileal nitrogen and starch digestibility improved in broilers fed the soft maize based diet, but no effect was seen for those fed hard or semi-hard maize based diets.…”

“…Feed represents the major cost of poultry production, constituting up to 70% of the total cost. Feeding whole grains to poultry has received much attention in recent years as an alternative management practice to reduce the feed cost, through savings in the cost of grinding, handling and processing of grains (Singh et al, 2015). This mode of feeding has not only shown positive effects on the performance but it also meets the consumer demands for a more 'natural' feeding system and improved animal welfare (Gabriel et al, 2007).…”

“…This mode of feeding has not only shown positive effects on the performance but it also meets the consumer demands for a more 'natural' feeding system and improved animal welfare (Gabriel et al, 2007). It is well documented that the incorporation of whole grains results in increased size and weight of the gizzard (Singh et al, 2015, Liu et al, 2015. A more developed gizzard enhances the grinding of feed that will increase the exposure of nutrients to digestive enzymes and improve bird performance (Ravindran et al, 2006;Rodriques and Choct, 2018).…”

SummaryUse of whole wheat, along with compounded feeds, for poultry feeding is a common practice in many parts of the world. However, studies investigating the use of other grains are limited. In the present study, the influence of including whole maize, with differing hardness, in broiler diets on the performance, nutrient utilisation and digestive tract development was examined. The experimental design was a 3 × 2 factorial arrangement of treatments, evaluating maize hardness (hard, semi-hard or soft) with diets based on ground maize or 115 g/kg whole maize replacing ground maize. The three maize cultivars were ground in a hammer mill to pass through a 4 mm sieve and six diets were developed based on one of the three cultivars. Following mixing, all diets were cold pelleted through a 3 mm die. Each of the six diets was fed to six replicate cages (eight birds per cage) from day 1 to 21 post-hatch. Maize hardness and whole maize inclusion had no effect (P>0.05) on weight gain. Maize hardness influenced (P<0.05) feed intake and feed per gain, while these two parameters were unaffected (P>0.05) by the inclusion of whole maize. The apparent metabolisable energy (AME) was unaffected (P>0.05) by maize hardness and whole maize inclusion. Maize hardness increased the ileal digestibility of nitrogen (P<0.05) and starch (P=0.06). The relative weight of the gizzard was greater (P<0.05) in birds fed hard and semi-hard maize compared to soft maize, and was greater (P<0.05) when whole maize was included. These results indicated that 115 g/kg of ground maize can be replaced by whole maize in broiler starter diets with no adverse effects on growth performance and thus can reduce the cost of feed manufacture.

“…With the added incidence of mild GI inflammation, birds would be even more susceptible to these pathogens. Several disease induction models for coccidiosis and necrotic enteritis capitalize on this increased susceptibility to infection, with acute exposure to Eimeria or Clostridium perfringens generally falling between 10 and 21 d ( Park et al., 2008 ; Lee et al., 2010 ; Singh et al., 2015 ; Barrios et al., 2017 ; Wilson et al., 2018 ). Further, early Salmonella Typhimurium exposure has resulted in increased susceptibility to NE infection ( Shivaramaiah et al., 2011 ), suggestive of a disruption to the GI tract that resulted in inflammation and pathogen susceptibility.…”

Evaluation of day of hatch exposure to various Enterobacteriaceae on inducing gastrointestinal inflammation in chicks through two weeks of age

Inappropriate microbial colonization can induce gastrointestinal ( GI ) inflammation may predispose poultry to opportunistic infections and reduce growth performance. Four independent experiments were completed to test ability of select Enterobacteriaceae isolates to induce GI inflammation. Experiments 1 and 2 included a non-inoculated control ( NC ), and a low ( L ), medium ( M ), or high ( H ) day of hatch ( DOH ) oral inoculation level. In experiment 1, birds in L1, M1, and H1 received 10 2 to 10 4 CFU of a mixed dose of 2 species of Citrobacter and Salmonella Enteritidis LB (SE). In experiment 2, birds in L2, M2, and H2 received 10 3 to 10 5 CFU of E. coli LG (LG) and included NC. Body weight was recorded on d 0, 7, and 14, with blood collected for chicken serum alpha-1-acid glycoprotein ( A1GP ) measurements on d14. Neither experiment resulted in differences in BWG, however, A1GP was increased ( P < 0.05) on d 14 when DOH inoculation dose 10 3 CFU/chick was used compared to NC. This observed increase in A1GP resulted in selection of 10 3 CFU/chick for DOH inoculation in experiments 3 and 4. Experiment 3 consisted of NC, E. coli Huff (Huff), and SE. On d 0, 7 and 15, BW was measured, with blood collected on d 15 for A1GP. Both d 15 A1GP and BWG from d 7 to 15 were reduced in inoculated chicks, Huff and SE, in experiment 3 ( P < 0.05). Experiment 4 evaluated NC and LG with BW measured on d 0, 2, 7 and 14. Yolk sacs were evaluated for retention and bacterial enumeration, and blood for serum A1GP were collected on d 2 and 14. Experiment 4 resulted in no differences in yolk sac parameters or A1GP, whereas there was an increase in BWG for LG from d 0 to 14 ( P < 0.05). When evaluated over time, serum A1GP increased between d 2 and d 14 by nearly 46% in LG, compared to negligible changes in NC ( P = 0.111). Mild GI inflammation induced by early Enterobacteriaceae exposure may not drastically impact growth or inflammation parameters but may increase susceptibility to opportunistic infection necessitating further study of this model.
