“…These results are similar to those reported by Nir et al (1995), Engberg et al (2002), Svihus et al (2004) and Cutlip et al (2008). These improvements have been variously attributed to increased nutritional density, increased nutrient intake, changes in the physical form of the feed, reduced feed wastage, decreased energy expenditure while eating (McKinney and Teeter, 2004;Skinner-Noble et al, 2005;Amerah et al, 2007;Cerrate et al, 2009;Yang et al, 2010), increased starch digestibility (Parsons et al, 2006), and improved apparent metabolisable energy (AME) and nutrient retention (Svihus et al, 2004;Adeyemi et al, 2008) mechanical action resulted in a rupture of the cell walls and thus made encapsulated nutrients of the feedstuff more accessible to digestive enzymes (Vande and Schrijver, 1988;Cutlip et al, 2008). Phytase and multienzymes plus phytase supplementation increased BW (3.3 and 4.6%) and BWG (3.7 and 4.9%), improved FCR (4.8 and 6.6%), and decreased feed intake by 1.6 and 2.2%, respectively, of the improvement in FCR as compared with those chicks fed a diet without enzyme supplementation.…”

A total of 210 unsexed 1-day old Arbor Acres broiler chicks were wing banded and randomly distributed among 30 cages of 7 birds per cage keeping equal initial BW during days 1-20 of age. A factorial design (2×3) was used in which there were two feed forms (mash vs crumble diet) and three enzyme treatments (unsupplemented, phytase, phytase plus multienzyme). Each treatment was replicated 5 times with 7 chicks per replicate. Body weight (BW), body weight gain (BWG) and feed conversion ratio (FCR) of fed chicks were significantly improved when the crumble diet was administered. However, feed intake of chicks fed on the crumble feeds was significantly lower than those fed the mash diet. Digestibility of ether extract and crude fiber was significantly greater in groups fed the crumble diet than those fed the mash diet. Enzyme supplementation significantly and similarly increased growth and production index, and improved FCR. Also greater digestibility of crude protein and crude ash was observed but growth during days 8-14 of age and crude fibre digestibility were significantly greater in chicks receiving the multienzyme plus phytase supplement than those receiving phytase alone. Crumble feed supplemented with multienzyme resulted in the highest performance and nutrient digestibility of broilers during days 1-20 of age.

“…Moreover, these authors found an improvement of 63 kcal of AME n /kg in the feed when the average particle size of corn was increased from 561 to 997 μm. Parsons et al (2006), obtained a quadratic AMEn response as size of corn increased in broiler feed form from 781 to 2,242 μm, obtaining the greatest result with average particle size of 1,042 μm.…”

Influence of feed form and corn particle size on nutrient digestibility and energy utilization by young turkeys

et al. 2012

-A digestibility trial with 16 to 21-day-old turkeys was conducted to study the effects of feed form and corn particle size on the coefficient of total intestinal tract apparent digestibility of dry matter (DM), nitrogen (N), ether extract (EE), aparent metabolizable energy (AME) and aparent metabolizable energy corrected by nitrogen balance (AME n ).A completely randomized experimental design in a 2 × 3 factorial arrangement -two feed forms (crumble and micropellet) and three average particle sizes of the corn (380, 606, 806 μm) -was applied. Three hundred and sixty 1-d-old B.U.T 9 male turkey poults were distributed into 36 cages, 6 replications of 10 birds, each one per treatment. Overall care of birds complied with welfare directive from the Universidade Federal do Paraná. Feed form did not affect the coefficient of total intestinal tract apparent digestibility of DM, N or crude fat (CF); however, an increase in corn particle size improved the coefficient of total intestinal tract apparent digestibility of DM, N and CF. AME and AME n were not affected by treatments. Feed form does not affect nutrient digestibility on young turkeys and grinding corn at an average particle size bigger than 380 μm improves nutrient digestibility.

“…The reduction of mean particle size in diets facilitates the contact between the endogenous enzymes and the dietary components. In chickens nutrient digestion and performance is related to the increase of particle size (Parsons et al, 2006;Amerah et al, 2007;Gonzá lezAlvarado et al, 2007), whereas the granulometry has controversial effects in mammals. In the pig, a reduction in feed particle size, often leads to an improvement of the digestibility in terms of energetic value and growth performance (Lawrence et al, 2003), although other studies showed no effect on digestibility and growth performance (Valencia et al, 2008;Solà -Oriol et al, 2009).…”

Feed particle size effects on morphology and glycoconjugate pattern was investigated in the rabbit intestine. Rabbits fed with fine particles (2 mm) displayed more irregularly shaped, higher duodenal villi and deeper crypts in distal colon as well as higher number of goblet cells than coarse (8 mm) fed ones. Brush border expressed: (i) in duodenum, neutral/sulfated glycoconjugates and glycans binding MAL II, SNA, Con A than KOH-sialidase-PNA and DBA reactivity in fine and coarse fed rabbits, respectively, (ii) in cecum, mainly sulfoglycans in coarse fed rabbits, MAL II and PNA staining in all samples, and (iii) in distal colon few sulfoglycans and MAL II reactivity. Enterocytes bound MAL II in duodenum, Con A in cecum, DBA, and Con A in distal colon of all rabbits, SNA in distal colon of coarse fed ones. Brunner's glands displayed high presence of acidic/sulfated mucins in fine fed rabbits, neutral glycoconjugates and reactivity with MAL II, SNA, PNA, KOH-sialidase-PNA, and Con A in all rabbits. Goblet cells exhibited: (i) in duodenum neutral and sulfomucins as well as MAL II and KOH-sialidase-PNA staining, than SNA and DBA in fine and coarse fed rabbits, respectively, (ii) in cecum sulfated glycans, MAL II, SNA, KOH-sialidase-PNA, DBA reactivity, and (iii) in distal colon acidic/sulfomucins, MAL II and SNA staining, and DBA reactivity in fine fed specimens. Crypt cells exhibited neutral and PNA reactive glycoconjugates in the cecum. In the distal colon also acidic/sulfated glycans, and MAL II, KOH-sialidase-PNA, DBA; SNA staining showed weaker reactivity in fine fed rabbits, which bound Con A.
