“…Rapeseed is an important oilseed crop with 7.41 million tons of rapeseed oil and 11.3 million tons of rapeseed meal ( RSM ) produced in 2018 (https://www.indexmundi.com/agriculture). There are different ways to produce rapeseed oil and its by-products, including heat-screw pressing, cold-pressing, and prepressing extraction (Unger, 1990; Bell, 1984; Hobson-Frohock, Fenwick and Heaney, 1977; Vig and Walia, 2001). First of all, rapeseed is preheated at 30 to 40°C, and then cooked at a high temperature (Unger, 1990).…”

The objective of this study was to evaluate the effects of rapeseed expeller cake (REC) derived from Brassica napus rapeseed with different concentrations of glucosinolate (Gls) and erucic acid (EA) on the egg-production performance, egg quality, apparent nutrient digestibility, and intestinal morphology in laying hens. At 33 wk of age, a total of 1,080 laying hens were randomly divided into 9 treatment groups in a completely randomized design involving a control treatment without REC (a corn–soybean diet) and a 2 × 4 factorial arrangement with 2 concentrations of REC (at 7 and 14%) from 4varieties of rapeseed varying in Gls and EA concentrations [DY6 REC: 22.67 μmol/g (Gls, relative to rapeseed meal), 0.7% (EA, relative to total fatty acids); MB1 REC: 43.23 μmol/g, 3.5%; DY5 REC: 74.66 μmol/g, 16.20%; XH3 REC: 132.83 μmol/g, 44.60%]. The trial lasted for 8 wk. Compared with the control group, REC addition decreased the ADFI, egg production, egg weight, and egg mass of laying hens during wk1 to wk4, wk5 to wk8, and wk1 to wk8 (P < 0.05), and REC did not affect FCR, mortality during wk1 to wk4, wk5 to wk8, and wk1 to wk8 (P > 0.05). The XH3 REC group had a trend to lower egg weight when compared with the DY6 REC group during wk1 to wk8 (P = 0.07).REC decreased AME and DM digestibility at wk8 (P < 0.01), and REC addition in diet did not affect apparent nitrogen digestibility (P = 0.6). REC decreased villi height (P < 0.01) and increased crypt depth (P < 0.01). The XH3 REC group had a lower crude fat digestibility than the DY6 REC group, and the crude fat digestibility of the DY5 and MB1 REC groups was lower than the XH3 REC group (P < 0.01). The DY6 REC group had a higher villi height than the DY5, MB1, and XH3 REC groups (P < 0.01). The XH3 REC group had a higher crypt depth than the DY6, DY5, and MB1 REC groups (P < 0.01). The DY6 REC group had a higher value of the ratio of villi height to crypt depth than the DY5 and MB1 REC groups, and the DY5 and MB1 REC groups had a higher value of the ratio of villi height to crypt depth than the XH3 REC group (P < 0.01).REC decreased albumen height and Haugh unit during wk1 to wk8 (P < 0.01 and P = 0.004), and increased yolk color during wk1 to wk8 (P < 0.01).The XH3, MB1, and DY5 REC groups had a lower albumen height than the DY6 REC group during wk1 to wk8 (P < 0.01), and the XH3 and DY5 REC groups had a lower Haugh unit than the DY6 REC group during wk1 to wk8 (P < 0.01). The DY6 REC group had the highest value of yolk color than other three varieties of REC (DY5, MB1, XH3) at wk6 and wk8 (P < 0.01 and P < 0.01). It can be concluded that the exposure of laying hens to REC with higher Gls and EA (DY5, MB1, XH3) led to a lower egg weight, nutrient digestibility, intestinal absorptive area, and egg internal quality than those with lower Gls and EA (DY6).

“…Canola is currently the leading oil seed crop in Canada with an annual production of over 15 million tonnes [ 23 ] and the importance of its meal as a protein supplement is second only to soybean meal. During crushing, canola seed yield 42 % of oil, which is used as vegetable oil for human consumption and 58 % meal, which is used as a protein source in animal feed [ 94 ]. The aim of this article is to review the recent studies in the use of canola meal as feedstuff for swine, the factors influencing its use and the strategies to overcome them.…”

Recent advances in canola meal utilization in swine nutrition

Canola meal is derived from the crushing of canola seed for oil extraction. Although it has been used in swine diets for a long time, its inclusion levels have been limited due to concerns regarding its nutritive value primarily arising from results of early studies showing negative effects of dietary canola meal inclusion in swine diets. Such effects were attributable to the presence of anti-nutritional factors (ANF; notably glucosinolates) in canola meal. However, due to advances in genetic improvements of canola that have led to production of cultivars with significantly lower ANF content and improved processing procedures, canola meal with a superior nutritive value for non-ruminant animals is now available. Therefore, the aim of this paper is to review the recent studies in the use of canola meal as feedstuff for swine, the factors influencing its use and the strategies to overcome them. First a historical overview of the development of canola is provided.
