“…Most available data in broilers (González-Alvarado et al, 2007;Jiménez-Moreno et al, 2009b;2013b;Sacranie et al, 2012) and pullets (Guzmán et al, 2015b) observed a reduction in gizzard pH with the inclusion of insoluble fiber sources in the diet. Highly lignified insoluble fiber sources, such as OH and SFH are retained longer in the gizzard, resulting in an increase in HCl production and, consequently, in a reduction in gizzard pH ).…”

“…The GIT was excised and divided into 7 portions: crop, proventriculus, gizzard, duodenum (from the gizzard junction to the entry of the bile and pancreatic ducts), jejunum (from end of the duodenum to Meckel's diverticulum), ileum (from Meckel's diverticulum to the ileocecal junction), and cecum. The segments of the GIT were clamped to avoid bolus contamination and the pH of all organs was measured in situ using a digital pH meter (Model 507, Crison Instruments S.A., Barcelona, Spain) as indicated by Jiménez-Moreno et al (2009b). The mean value of 2 measurements taken in each of the 2 birds was used for further evaluation.…”

“…Particle size distribution and mean particle size of the SFH and diets, expressed as geometric mean diameter ± log geometric standard deviation (GMD ± GSD), were determined in 100 g samples using a Retsch shaker (Retsch, Stuttgart, Germany) provided with 8 sieves ranging in mesh from 40 to 5,000 μm, as described by the ASAE (1995). The water-holding (WHC, mL/g DM) and swelling (SWC, mL/g DM) capacity of the SFH was determined as indicated by Jiménez-Moreno et al (2009b). Acid-insoluble ash was analyzed as proposed by De Coca-Sinova et al (2011).…”

The effects of including 3% sunflower hulls (SFH) in the diet on growth performance, nutrient retention (TTAR), and gastrointestinal tract (GIT) traits were studied in chicks from zero to 21 d of age. Four treatments that resulted from the combination of 2 chicken lines (female broilers vs. brown pullets) and 2 levels of SFH (zero vs. 3%) were used. The control diet contained 2,980 kcal AME n /kg, 1.25% digestible Lys, and 8.7% neutral detergent fiber. The experimental diet included 3% SFH at the expense (wt:wt) of the whole diet. Growth performance, TTAR of nutrients, and the AME n of the diet were greater (P = 0.097 to P < 0.001) in broilers than in pullets. In absolute terms, all the organs of the GIT were heavier (P < 0.001) and the small intestine and cecum were longer (P < 0.001) in broilers than in pullets. At 21 d of age, however, the relative weight (% BW) of all the organs of the GIT (P < 0.001) and the relative length (cm/kg BW) of the small intestine and cecum (P < 0.01) were greater in pullets. Gizzard pH (P < 0.001), total short chain fatty acids concentration in the cecum (P = 0.098), and villus height (P < 0.001) and crypt depth (P < 0.05) of the ileum mucosa were higher in broilers. The inclusion of SFH increased (P < 0.05) the AME n content of the diet but did not affect bird performance, moisture content of the excreta, or the concentration and profile of fatty acids in the cecum. Dietary SFH increased gizzard weight and reduced gizzard pH (P < 0.001) at both ages. In conclusion, broilers had better growth performance, nutrient retention, and ileum absorptive capacity than pullets. The inclusion of 3% SFH at the expense of the control diet did not have any negative effect on chick performance and, in fact, increased gizzard weight, reduced gizzard pH, and improved the energy content of the diet.

“…The weight of the organs was expressed relative (g/kg) to live BW and the weight of the gizzard contents was expressed as a percentage of the full organ weight. Gizzard pH was measured in situ in duplicate in all these hens using a digital pH meter fitted with a fine tip glass electrode (model 507, Crison Instruments S.A., Barcelona, Spain) as indicated by Jiménez-Moreno et al (2009b). The length of the duodenum (from the gizzard to the pancreo-biliary ducts), jejunum (from the pancreo-biliary ducts to the Meckel's diverticulum), ileum (from the Meckel's diverticulum to the ileocecal valve) and of the two ceca (from the ostium to the tip of the right and left ceca) was also measured.…”

“…However, Nir et al (1994) and Serrano et al (2013) in broilers and Guzmán et al (2015a) and Saldaña et al (2015a, b) in pullets, have shown that feeding crumbles or pellets reduced the relative weight (g/kg BW) of the gizzard and the development of the gastrointestinal tract (GIT) as compared with feeding mash. Also, when the energy concentration of the diet increases, fiber content decreases, which also reduces GIT development (González-Alvarado et al, 2007;Jiménez-Moreno et al, 2009a;Sacranie et al, 2012). A poorly developed GIT affects feed intake and might result in pullets not consuming enough energy to meet their requirements for optimal egg production during the first weeks of the laying phase (Pérez-Bonilla et al, 2012b;Guzmán et al, 2016).…”

a b s t r a c tThe influence of feed form and energy content of the rearing phase diets on hen productivity, gastrointestinal tract (GIT) traits and body measurements was studied in brown-egg laying hens fed diets differing in energy concentration from 17 to 46 wk of age. The experiment was completely randomized with 12 treatments arranged as a (2 × 3) × 2 factorial with two feed forms (mash vs. crumbles) and three AME n concentrations of the rearing phase diets (low, medium and high) and two AME n concentrations (11.10 vs. 11.52 MJ/kg) of the laying phase diets. The AME n of the rearing phase diets differed in 0.42 MJ/kg in all three periods (1-5 wk, 5-10 wk and 10-17 wk of age). Hen productivity was determined from 17 to 46 wk and GIT and body traits were measured at 46 wk of age. The characteristics of the rearing phase diets did not affect any of the production, GIT traits or body measurements studied during the laying phase, except body weight gain (BWG) from 17 to 46 wk of age that was higher (P < 0.01) in hens that were fed mash during the rearing phase than in hens that were fed crumbles. An increase in the energy content of the laying phase diet from 11.10 to 11.52 MJ AME n /kg reduced feed intake (P < 0.001) and improved feed conversion ratio (P < 0.001) from 17 to 46 wk and reduced gizzard contents (P < 0.01) at 46 wk of age but did not affect any of the other production trait studied. The characteristics of the rearing and laying hen diets did not affect any of the GIT traits or body measurements at 46 wk of age. Body weight of the hens was positively (P < 0.001) related with body length, body mass index, tarsus length and tarsus diameter at this age. The data indicate that neither feed form nor energy concentration of the rearing phase diets affected subsequent hen performance. An increase in the AME n content of the layer diet from 11.10 to 11.52 MJ/kg decreased feed intake and improved feed conversion ratio but did not affect hen production or egg quality.
