“…In the present study, dietary fiber in broiler diets contributed to an increase in the duodenal villus height. Sittiya et al (2016) and Jiménez-Moreno et al (2011) reported an improvement in the villus height:crypt depth ratio in broilers with the inclusion of whole rice grain and pea hulls, respectively. In addition, Sklan et al (2003) found that the surface area of the small intestine of turkeys increased as the level of crude fiber in the diet increased from 2.7 to 7.9%.…”

The present study was conducted to investigate the effects of dietary fiber source levels on the fecal ammonia nitrogen, growth performance, carcass traits, gastrointestinal tract development, and intestinal morphology of broilers. A total of 420 one-day-old unsexed broiler chicks were individually weighed and randomly divided into 5 groups, each with seven replicates of twelve chicks. Rice hulls (RH) and soybean hulls (SH) were ground through a hammer mill with a 2-mm screen. The RH and SH experimental diets were as follows: 0% (control); 2.5% RH; 2.5% SH; 5% RH; and 5% SH. No significant differences were found in growth performance and fecal ammonia nitrogen among the dietary treatment groups (p>0.05). Compared with the control, the experimental diets with 2.5% SH significantly decreased the wing weight of chickens (p<0.05), while no significant differences in the weight of the other visceral organs were observed. Compared with the control, broilers in the 5% SH group had a longer jejunum and ileum (p<0.05). Feeding the broilers SH and RH had no effect on the villus area and crypt depth of the intestine. Compared with the control, the experimental diet with 2.5% RH significantly increased the duodenal villus height of chickens (p<0.05). These findings suggest that the inclusion of 5% SH in the diets resulted in improved intestinal morphology without negatively affecting growth performance and carcass traits.

“…Under the trend of increasing global demand for corn, poultry producers are being forced to seek local raw materials to replace corn in animal feed. A large number of researchers have investigated the effect of different feed ingredients on the performance of poultry such as rice bran [ 1 , 2 ], defatted rice bran [ 3 , 4 ], paddy rice [ 5 , 6 , 7 ], whole wheat [ 8 , 9 , 10 ] and millet [ 11 , 12 , 13 ]. China is the largest rice producer in the world, accounting for 27.63% of global rice production [ 14 ].…”

This study investigated the effect of replacing dietary corn with broken rice (BR) on goose growth performance, body size and bare skin color. In total, 240 28-day-old healthy male Yangzhou goslings with similar body weight (BW) were randomly divided into five groups, with six replicates per group and eight geese per replicate. The control group was fed with a corn-soybean meal. The BR25, BR50, BR75 and BR100 groups had 25%, 50%, 75% and 100% of corn replaced with BR, respectively (corresponding to 15.95%, 31.88%, 47.63% and 62.92% of BR in the feed, respectively), each with constant metabolizable energy (ME) to crude protein (CP) ratio (ME/CP). At 28, 42, 56 and 70 d, BW and feed intake for each pen were measured. Blood was collected, and body size and bare skin color were evaluated at 70 d. The results showed that different BR replacement proportions had no effect on BW at 42, 56 or 70 d or on average daily feed intake (ADFI) or average daily gain (ADG) from 28 to 42 d (p > 0.05) but BR50 and BR75 decreased the feed/gain ratio (F/G) from 28 to 42 d (p < 0.05). From 42 to 56 d, BR75 and BR100 geese had a lower ADFI than the control geese (p < 0.05), and BR75 and BR100 geese had a lower F/G than the BR25 geese (p < 0.05). Group BR50, BR75 and BR100 geese had a lower ADFI from 56 to 70 d than the control geese (p < 0.05). From 28 to 70 d, BR50, BR75 and BR100 groups had a lower ADFI (p < 0.05). Interestingly, the control and BR25 groups had a higher flipper score than the BR50, BR75 and BR100 groups (p < 0.05), and the control group had a higher flipper score than the BR25 group (p < 0.05). All BR groups reduced the bill scoring (p < 0.05). Different BR replacement proportions did not negatively affect serum biochemical variable at 70 d (p > 0.05). Overall, under these conditions, BR can totally replace corn in goose diets, and we recommend 75% replacement of corn with BR from 28 to 70 d.

“…Rice stored for a long time is rejected for human consumption because of its low eating quality, and is thus being supplied for feedstuff at prices competitive to those of cereal grains. As a potential feedstuff, brown rice (BR) has been used in feeding trials in poultry diets and has demonstrated similar efficiency to corn grain in egg production or growth [1,2]. Sittiya et al [3] also reported that laying performance and egg qualities, except for yolk color, were not influenced by dietary treatment in which corn was replaced with rice at different levels.…”

Two experiments were conducted to determine apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and ileal digestible amino acid (AA) content of brown rice (BR) and to investigate the effect of dietary supplementation of BR on laying performance and egg quality of laying hens. In Exp. 1, 72 Hy-line Brown layers (49-week-old) were allocated to two treatments using a completely randomized block design, and each treatment included six cages per treatment and six hens per cage. A semi-purified diet was formulated to include BR as the sole source of AA and energy and an N-free diet was used to determine basal endogenous loss of AA. The hens were fed a commercial layer diet for adaptation to the experimental environment and diet for 7 days from d 0, and then fed experimental diets for 5 days from d 7. Excreta were collected from d 10 to 11 and ileal digesta were collected on d 12. On a dry matter (DM) basis, the AME and AMEn of BR was determined at 3,773 and 3,729 kcal/kg, respectively. The apparent ileal digestibility (AID) of BR ranged from 32.7% for Thr to 73.7% for Arg. The range of the standardized ileal digestibility (SID) value was between 79.4% for Met and 96.6% for Lys. In Exp. 2, 252 Hy-line Brown layers (44-week-old) were divided into four groups, comprising seven replicates of nine birds each and assigned to four experimental diets containing 0 (Control), 5%, 10%, or 15% BR for 5 weeks. The BR-containing diets were formulated to be equal in the content of AMEn and digestible AA to those of the diet without BR. No significant differences were observed in laying performances. Egg quality and blood profiles were not linearly or quadratically affected by dietary treatments. These results suggest that up to 15% BR can be included into layer feed without any adverse effects on laying performance and egg quality, if its energy and digestible AA values are well evaluated.
