“…In pigs fed RSM together with RS, the increase in thyroid, liver and kidney weight and decrease in secretion of T 3 and T 4 were not, however, directly proportional to GL intake. In comparison with the results of our previous experiments (Chabiera et al, 1994;Fandrejewski et al, 1994) on feeding RSM to fattening pigs, a weaker goitrogenic response to an increase of the GL level in the ration was found (from 2.1 to 7.3 mM/d). This was all the more surprising since along with the seeds, myrosinase (Bille et al, 1983a) was probably also introduced into the digestive tract of the animals.…”

Twenty-four Polish Landrace pigs (12 gilts and 12 barrows) fattened from 30 to 95 kg body weight were fed diets containing 18% rapeseed meal (RSM) and full-fat rape seeds (RS) in the following amounts: 0 (group RS-0), 10 (group RS-10) or 20% (group RS-20). The pigs were fed on an individual basis with rations having equal energy, protein and lysine contents. Nitrogen balance was determined at 40, 60 and 80 kg liveweight. Metabolizable energy and protein utilization were determined by the slaughter technique. The thyroid gland, liver and kidneys were weighed and plasma T 3 and T 4 levels assayed. Nitrogen retention was on average 12 and 17% lower (P< 0.01) in groups RS-10 and RS-20 than in RS-0; the negative effect of rape seeds on nitrogen utilization intensified as fattening progressed. Metabolizable energy utilization in pigs receiving 20% RS was 2.5 and 3.4% worse (P <0.05) than in groups RS-10 and RS-0, respectively. As glucosinolates intake increased, the weight of the internal organs rose and T 3 and T 4 levels declined. These changes were not, however, proportional to the amount of glucosinolates intake. The combined use of RSM and RS in the diets of growing pigs had an unfavourable effect on protein and energy utilization.

“…It is well established that GL cause liver enlargement as well as depression of feed intake and growth for pigs as well as other animal species (Bell 1984). For example, pigs fed diets containing 210 g kg -1 of low-glucosinolate rapeseed meal had liver weights that were 16% heavier than their soybean meal-fed counterparts (Chadiera et al 1994).…”

R. 2007. Growth performance, carcass characteristics and pork quality of pigs receiving diets containing meal from conventional or glyphosate-tolerant canola. Can. J. Anim. Sci. 87: 517-526. Growth performance, carcass characteristics and pork quality were evaluated for pigs fed barley and wheat-based diets, which included meal from conventional or transgenic glyphosatetolerant (Roundup-Ready ® ) canola. One hundred and forty-four pigs (72 gilts and 72 barrows) weighing 30 ± 3 kg were assigned, three to a pen, on the basis of gender and weight to receive one of four dietary treatments formulated using canola meal from two commercial sources (COM1 and COM2), non-transgenic parental control (PCC) or transgenic (RRC) canola. Pigs were fed a grower diet (75 g kg -1 canola meal) until 60.5 ± 4.0 kg and then a finishing diet (150 g kg -1 canola meal) to 108.6 ± 7.3 kg at slaughter. Pigs receiving the COM1 and COM2 diets had an overall higher (P < 0.0001) daily feed intake (DFI) compared with pigs fed the PCC and RRC diets. Corresponding average daily gain (ADG) was also increased (P = 0.02) for COM1-fed pigs, although feed conversion efficiencies (FCE) of the pigs were similar (P > 0.05) among diets. Gilts had lower overall DFI (P < 0.0001), ADG (P < 0.0001) and FCE (P = 0.04) compared with barrows. Pigs receiving the PCC and RRC diets had heavier (P = 0.002) liver weights than those pigs fed the COM1 and COM2 diets (2.06 and 2.05 kg vs. 1.95 and 1.96 kg, respectively). Postmortem decline in pH and temperature of the longissimus thoracis (LT) muscle from pigs were not different (P > 0.05) among the dietary treatments. Characteristics of pork quality for the LT muscle, which included objective colour and shear force were also not affected (P > 0.05) by dietary source of canola meal. Gross composition of commercial pork cuts were similar (P > 0.05) among the dietary treatments with the exception of small differences for intermuscular (P = 0.04) and body cavity (P = 0.02) fat in the picnic cut and body cavity (P = 0.02) fat in the loin cut. Differences in DFI, ADG and liver weights of the pigs may be related to higher content of antinutritional glucosinolates (µmoles g -1 ) in the PCC (20.20) and RRC (15.04) varieties compared with COM1 (7.55) and COM2 (7.46) sources of canola meal.Key words: Transgenic canola, growth, pork quality, pigs Caine, W.
