Abstract

Elsevier Alagón, G.; Arce-Cabrera, ON.; Martinez-Paredes, E.; Ródenas Martínez, L.; Moya, V.; Blas Ferrer, E.; Cervera Fras, MC.... (2016). Nutritive value of distillers dried grains with solubles from barley, corn and wheat for growing rabbits. Animal Feed Science and Technology. 222:217-226. doi:10.1016/j.anifeedsci.2016.10.024 Nutritive value of distillers dried grains with solubles from barley, corn and wheat for 1 growing rabbits 2 (on av. +70 g kg -1 DM). DDGS' protein was richer in proline, phenylalanine, valine and 27 arginine for barley DDGS (107, 55, 54 and 51 g kg -1 CP, respectively), in leucine, alanine and 28 histidine for corn DDGS (114, 75 and 27 g kg -1 CP, respectively), and in glutamic acid for 29 wheat DDGS (290 g kg -1 CP). Barley DDGS was richer in saturated (236 g kg -1 total fatty 30 acids), corn DDGS in monounsaturated (278 g kg -1 total fatty acids) and wheat DDGS in 31 polyunsaturated fatty acids (615 g kg -1 total fatty acids). Barley DDGS was characterized by the 32 lowest nutritive value traits of DDGS evaluated (11.9 MJ digestible energy (DE) and 168 g 33 digestible protein (DP) kg -1 DM). In spite of higher protein and lower fibre content of the 34 Brazilian corn (+1.7 g CP and −31 g neutral detergent fibre kg -1 DM), no significant differences 35 for the nutritive value of both corn DDGS were observed (on av. 15.3 MJ DE and 208 g DP kg -1 36 DM). Wheat DDGS might be considered as the DDGS with the highest nutritive value of those 37 evaluated (15.7 MJ DE and 263 g DP kg -1 DM). 38 39

Do Growing Rabbits with a High Growth Rate Require Diets with High Levels of Essential Amino Acids? A Choice-Feeding Trial

“…The amino acids were derivatised with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC) and separated with a C-18 reverse-phase column Waters AcQ Tag (150 mm × 3.9 mm). Methionine and cystine were determined separately as methionine sulphone and cysteic acid, respectively, after performic acid oxidation followed by acid hydrolysis [ 30 ]. Ytterbium was analysed according to [ 27 ] by absorption spectrometry (Smith-Hieftje 22; Thermo Jarrell Ash, MA, USA).…”

The impact of lamb diets containing either barley or corn on growth performance and carcass quality

“…Whole grains, such as barley (BAR) and corn (CORN), are the main ingredients in lamb diets since the availability of good quality forage in Jordan is limited by the harsh environment [ 4 ]. The nutritive value of BAR and CORN is reflected mainly in energy content; protein is considered of secondary importance [ 5 ]. In Jordan, CORN costs 50%-80% more than BAR.…”

Use of Barley, Wheat and Corn Distiller's Dried Grain With Solubles in Diets for Growing Rabbits: Nutritive Value, Growth Performance and Meat Quality.

“…However, the apparent digestibility of DDGS lysine used in this study was adequate (Alagón et al, 2013a) probably due to the formation of microbial lysine at caecum level (Belenguer et al, 2012), which is subsequently ingested during caecotrophy.…”

“…However, the use of DDGS may affect the quality of both carcass and meat. Typically, DDGS contain 7 to 15% of fat, with 70 to 80% of mono and polyunsaturated fatty acids (Xu et al, 2010;Alagón et al 2013a) and monogastrics tend to show a fatty acid profile in the meat similar to the profile of the diet (Bee et al, 2002;Dalle Zotte, 2002).…”

“…These products have high potential to be included in formulation and manufacture of diets for rabbits because they are characterized by being good sources of digestible energy (11.9 -15.7 MJ kg DM), digestible protein (16.8 -26.3%), fat (7.2 -14.4%) and soluble fibre (20 -21.7%) Alagón et al, 2013a), allowing an adequate growth performance when they are included up to 20% in the diet (Youssef et al, 2012;Alagón et al, 2013b).…”
