“…This could be attributed to the lower CM glucosinolates and sinapine of our dietary CM that was not adequate to affect the FI. The current findings are in line with previous reports on CM usage in broiler chickens without any effect on FI (Payvastegan et al, 2013;Gopinger et al, 2014;Aljuobori et al, 2016;Zhang and Adeola, 2016 An increase in dietary level of CM reduced BWG of the chickens. This could be due to presence of antinutritional factors mainly fiber (12.9%) and glucosinolates (23.5 μmol/g) in the CM.…”

“…Analysis of experimental diets demonstrated increase in crude fiber content from 3.05 to 3.86, 4.67 and 5.46% during starter phase, 2.97 to 3.81, 4.67 and 5.47% during grower phase and 2.85 to 3.65, 4.47 and 5.27% during finisher phase after the addition of 10, 20 and 30% of CM, respectively. Dietary fiber content of CM have been demonstrated to be inversely related to energy digestibility as well as protein digestibility (Khajali and Slominski, 2012;Gopinger et al, 2014;Bovera et al, 2014).…”

“…Payvastegan et al (2013) observed no adverse effect of CM in the inclusion rate of 20% of the broilers diet. Gopinger et al (2014) also found that CM can be added up to 16.7% in diets for broiler without affecting the key variable of growth performance.…”

This study was carried out to determine the effects of dietary inclusion level of canola meal (CM) on performance, organ weights and hepatic type I deiodinase gene expression in broilers. A completely randomized design with 4 levels of CM (0, 10, 20 and 30%) as a substitute for soybean meal (SBM) was utilized with 5 replicates of 9 birds each. The results showed that body weight gain (1 to 42 d) decreased linearly (P＜0.01) as the inclusion of CM increased. An increase in dietary level of CM also resulted in a linear (P＜0.05) increase in feed conversion ratio (1 to 42 d). Proportion of thyroids (P＜0.05) and liver (P＜0.01) increased linearly with increased levels of CM. A significant linear increase in right ventricular weight: total ventricular weight ratio (P＜0.01) and heart weight (P＜ 0.05) were observed by substituting CM for SBM. The concentration of plasma triiodothyronine and triiodothyronine: tetraiodothyronine ratio decreased linearly (P＜0.01) with increasing level of CM. Expression of hepatic type I deiodinase gene (D1) decreased linearly (P＜0.01) as inclusion level of CM in diets increased. Moreover, increasing linear (P＜0.01) and quadratic responses (P＜0.05) were observed in follicles number and epithelial thickness in broilers thyroids followed by increased levels of CM. In addition, increases in dietary CM inclusion led to a linear (P ＜0.01) increase in thyroid follicles diameters. In conclusion, the results of this study indicate that feeding increasing CM inclusions from 0 to 30% negatively affect growth performance of broiler chickens. From this study, it can also be concluded that substitution of CM for SBM adversely interferes with thyroid and liver functions and decrease D1 gene expression, likely because of higher dietary concentration of glucosinolates.

“…The ATTD of CP was much lower compared to a value reported by Gopinger et al (2014); they tested an inclusion of 40% canola meal as a substitute for soybean meal in broiler chicken diets, which resulted in ATTD of CP at 0.74. This was a combined effect of soybean and rapeseed protein digestibility that contributed to a greater overall digestibility of protein.…”

The current study assessed the effect of rapeseed variety and oil extraction process on the apparent and standardised ileal digestibility (AID, SID) of crude protein (CP) and amino acids (AA) in rapeseed co-products in broiler chickens. PR46W21 and DK Cabernet rapeseed varieties were de-oiled by soft and standard hexane extraction, producing soft rapeseed meal (SRSM) and rapeseed meal (RSM), respectively. The soft, non-standard hexane extraction method was designed to reduce heat treatment that occurs prior to hexane extraction in order to maximise potential genetic differences in digestibility values of rapeseed co-products. The test meals were incorporated into semi-synthetic diets at a level of 500 g/kg; diets were fed to 14-day old paired chickens (n=6 pairs) for ten days, when ileal digesta was collected post-slaughter from Meckel's diverticulum to the ileal-caecal junction.The AID and SID of CP and AA were determined using titanium dioxide as inert dietary marker. The variety PR46W21 showed a greater AID and SID of CP, arginine, leucine, methionine, cysteine, phenylalanine, valine and lysine in RSM compared to the DK Cabernet RSM (p < 0.05). The soft processing increased AID and SID of CP, histidine and lysine in SRSM of PR46W21 and DK Cabernet compared to their RSM counterparts (p<0.05). An interaction between variety and processing was only observed for AID and SID of tryptophan (p < 0.001), as only in PR46W21 standard processing reduced the tryptophan SID compared to its soft processed counterpart. The data support the view that the selection of rapeseed variety and modification of thermal treatment during the oil extraction might improve nutritional value of rapeseed meals.

“…; however, its inclusion rate is limited by its high fiber content. The literature indicates the use of RSM in broiler diets at (Gopinger et al 2014) who formulated RSM diets with crude fiber ranging between 4.4 and 6.7%. This is likely due to differences in the formulation of the objective and the constraints used (i.e., maximum fiber requirements) in the current study versus other studies.…”

Time series livestock diet optimization: cost-effective broiler feed substitution using the commodity price spread approach

2017

View full text Add to dashboard Cite

Sustainable feed formulation (defined here as nutritional and economic feed optimization) is substantial in feed chain production from crop farmers to livestock producers. Diet formulation employing a static linear programming (LP) approach, which is widely used in trading firms and feed production facilities, does not allow for intertemporal flexibility. Our approach allows the interaction between feed components over time, considering the volatile global feed prices, thereby improving sustainability in feed formulation and feed availability. The objectives of this study were to (1) develop a multi-stage LP feed model, (2) demonstrate its potential use in broiler feeding, and (3) illustrate the impact of feed input price spread (variation) on the composition of broiler diets. Modeling resulted in reciprocal relationships between conventional feeds and byproducts at different rates. Based on the price spreads expressed as a percentage of DDGS (distiller's dried grains with solubles) price compared to corn price, three positions of dietary switch were identified; corn-DDGS price spreads of higher than 94%, between 76 and 94%, and lower than 76% corresponding to limited/no inclusion, partial inclusion, and maximum replacement of corn by DDGS, respectively. Rapeseed meal inclusion was 4, 5, and 6% in the corn-based starter, grower, and finisher diets, respectively, and its potential to replace soybean meal was limited by its higher fiber content. Based on the simulated compound feed prices, the global broiler feed industry could gain 1.7 billion USD through improved resources planning.
