Effect of Replacing Dietary Corn with Broken Rice on Goose Growth Performance, Body Size and Bare Skin Color

Abstract

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.

Effects of dietary paddy rice on growth performance, carcass traits, bare skin color, and nutrient digestibility in geese

“…In this study, the replacement of dietary corn with paddy rice resulted in a lighter yellow coloration of the bill of goslings. Similar results were reported for broken rice by Chen et al. (2020) .…”

“…In addition, paddy rice may affect goose skin color due to a lack of xanthophylls and carotenoids. Skin color is a major concern issue for consumers in the marketplace, especially in China ( Chen et al., 2020 ).…”

Diagnostic value of miR-637 in patients with atherosclerosis and its predictive significance for the future cardiovascular events

“…Triglycerides (TG) and total cholesterol (TC) were measured by enzymatic and cholesterol oxidase method, respectively. Serum high-density lipoprotein (HDL) and LDL were assayed by the direct method 17. Fasting blood glucose levels were measured monthly using an Accu-Chek glucometer (Roche Diagnostics GmbH, Mannheim, Germany) 18…”

Controlling the Properties of Starch from Rice Brokens by Crosslinking with Citric Acid and Sodium Trimetaphosphate

“…[2,3] A large fraction of this underutilized industrial by-product is transformed into flour used as raw material in the preparation of food and feed. [4,5] Although broken rice holds the same proximal composition and medicinal benefits, it has been mainly explored to produce bioethanol, [6,7] lactic acid, [8,9] and wine [10] in last decade. However, a significant portion of rice used in pet food, and brewery industry are high-grade DOI: 10.1002/star.202200094 broken rice, whereas low-quality ones are hardly used.…”

“…Starch is the most abundant biopolymer of glucose molecules linked together with 𝛼-d- (1,4) and 𝛼-d- (1)(2)(3)(4)(5)(6) linkages. [15] Though native starch holds considerable functional properties, it has many weaknesses like sensitivity to pH, higher retrogradation, poor paste clarity, low thermal stability, and lower solubility.…”
