The experiment was conducted to measure the effects of Camelina sativa expeller on the performance of broiler chickens and on the sensory quality and fatty acid composition of broiler meat. One-day-old broiler chickens were randomly allocated to the three dietary treatments which lasted 37 days. Experimental diets contained 0, 5 or 10% C. sativa expeller. Feed and water were offered ad libitum. The birds were weighed at the beginning, at 14 days and at the end of the trial at 37 days. Feed intake was recorded between weighings. C. sativa expeller reduced the growth of the birds linearly (P < 0.001). It also depressed their feed intake and feed conversion ratio during the starter phase (1-14 days). C. sativa did not cause any significant enlargement of the thyroid gland, nor were any liver lesions observed. Feeding of C. sativa significantly (P < 0.001) increased the omega-3 fatty acid level in broiler meat. This was mainly due to an increase in α-linolenic acid (18:3, n-3). Feeding did not seem to have any adverse effect on the sensory quality of broiler meat. Meat from female broilers produced by feeding 5% C. sativa in the diet was significantly (P = 0.02) more tender than meat produced by feeding 10% C. sativa.

“…This is in accordance with the results of Castell and Cliplef (1993), who reported no differences in the organoleptic meat quality of pigs offered barley-soya bean meal diets or barley-rapeseed meal diets in which rapeseed meal was gradually replaced with peas. Siljander-Rasi et al (1996) reported no differences in organoleptic meat quality in pigs offered diets in which soya bean meal was gradually replaced with rapeseed meal. In our study, no relationship was found between organoleptic meat quality and carcass lean percentage or fat thickness, which is in accordance with the results of Blanchard et al (2000).…”

Two experiments were carried out to study the effects of using the new faba bean (Vicia faba L.) cultivar Kontu as a domestic protein source for growing-finishing pigs. In Experiment 1, 120 pigs were used with a body weight (BW) of 25-110 kg to study the effects of replacing 0, 25, 50, 75, and 100% of rapeseed meal with faba beans in barley + rapeseed meal based diets. Restrictedly fed grower and finisher diets contained 137-317 and 114-260 g kg -1 faba beans, respectively. A barley + soya bean meal based diet was included as a control. The replacement of rapeseed meal with faba beans exerted a quadratic effect on daily weight gain and on the feed conversion ratio of pigs in the growing period and during total fattening (P < 0.05). The growth rate of growing pigs declined when 75 or 100% of rapeseed meal was replaced with faba beans. In addition, the complete replacement of rapeseed meal with faba beans decreased feed consumption (P < 0.05). The best overall growth performance and feed conversion ratio were observed when 50% of rapeseed meal was replaced with faba beans. These pigs had a better feed conversion ratio than those fed a barley + soya bean based meal diet (P < 0.05). The Minolta L* value of the longissimus dorsi muscle decreased linearly (P < 0.01) with increasing dietary faba bean levels. This indicates that the meat became darker. Therefore, Experiment 2 was carried out with 20 pigs (25-107 kg BW) to study the effect of faba beans on the colour and ultimate pH of the meat. The pigs were fed barley + soya bean meal or barley + faba bean based diets (243 g kg -1 faba beans). The ultimate pH of the longissimus dorsi muscle was higher in pigs fed the faba bean diet (P = 0.05), but meat colour did not differ between the treatments (P > 0.05). In conclusion, inclusion of over 200 g kg -1 of faba beans in barley + rapeseed meal based diets is not recommended for growing pigs because it may result in reduced growth performance. Faba beans may influence meat colour, but this phenomenon should be investigated further.

“…Samples were taken from the longissimus dorsi muscle before the last rib from 37 and 60 randomly selected carcasses in Experiments 2 and 3 (one pig per pen), respectively, for the determination of organoleptic quality. The frozen samples were thawed and prepared for sensory evaluation as described by Siljander-Rasi et al (1996). A trained, seven-member test panel graded the fried samples for tenderness, juiciness, and taste using a 7-point rating scale (1 = very tough, very dry, weak pork flavour; 7 = very tender, very juicy, strong pork flavour).…”

In 2000, EU regulations for organic animal production set new guidelines for organic pig feeding requiring that this be based on mainly home-grown organic feedstuffs. Doubts were however raised whether these feeding regimes can maintain good growth performance and carcass quality of pigs. Three experiments were carried out to study different organic feeding regimes in weaned piglets and fattening pigs. In Experiment 1, we evaluated the use of peas and faba beans (0, 120, or 240 g kg -1 ) in diets for weaned piglets. Piglets fed pea diets performed as well as those fed the control diet, whereas the highest faba bean level resulted in reduced feed intake and growth performance. In Experiment 2, we studied the replacement (0, 33, or 67%) of rapeseed cake with blue lupins in fattening pig diets. The dietary lupin level had a quadratic effect on the weight gain of growing pigs, the best performance being observed at the 33% replacement level. However, dietary lupin level did not influence weight gain during the finishing period and total fattening. Back fat became softer with increasing dietary lupin levels. In Experiment 3, different protein supplements were compared in organic diets from weaning to slaughter. In two-phase feeding, the best performance was observed when whey protein was used as the protein supplement, followed by soya bean cake + whey protein and rapeseed cake + fish meal. The effects of a one-phase organic feeding regime with coldpressed rapeseed cake + whey protein did not differ from those of the two-phase organic feeding regimes. Fattening pigs fed organic diets required from two to seven days longer to reach slaughter weight than those fed conventional diets. Pigs fed organic diets had fatter carcasses, but the eating quality of organic pork did not differ from that of pork from pigs fed conventional diets. Feed costs and the circulation rate of pigs, weaners in particular, were greater and carcass prices lower in the organic feeding regimes than in the conventional ones.
