Two trials were designed to determine the quality of pig carcasses, chemical composition and physical indicators of meat and fatty acid composition of backfat. Growing pigs were offered adequate diets containing field beans (20–25%), sweet lupines (15–20%) or extruded soybeans (18–15.4%) instead of soybean or sunflower oil meal (control). The weight and length of the carcass, dressing percentage, weight of ham, chemical composition and physical indicators of meat of pigs fed diets with different leguminous seeds did not differ significantly from those of pigs fed the control diet. Pigs fed diets containing field beans had 5.7–8.2 mm lower backfat thickness, while pigs fed extruded soybeans had 6.6–7.9% smaller loin lean area and 4.57% lower content of oleic acid in the backfat, but the content of linoleic acid was 5.11% higher.

Mehdi, Y., Clinquart, A., Hornick, J.-L., Cabaraux, J.-F., Istasse, L. and Dufrasne, I. 2015. Meat composition and quality of young growing Belgian Blue bulls offered a fattening diet with selenium enriched cereals. Can. J. Anim. Sci. 95: 465–473. The objective of this study was to evaluate the effects of selenium (Se) enrichment of cereals on the performance of Belgian Blue bulls, meat quality and chemical composition. Twenty-three bulls were used in the present study. Twelve bulls were offered a control diet containing Se at a basal concentration of 58 µg kg−1 of dry matter (DM) and the other 11 bulls were given a diet containing 173 µg kg−1 DM of Se by means of Se-enriched spelt and barley. The Se enrichment of the diet did not affect the growth performance, the slaughter data or meat quality (P > 0.05). There were no effects of Se on tenderness, oxidative rancidity and water losses. However, there were some effects of Se enrichment on the meat chemical composition. The ether extract was decreased from 2.1 to 1.7% DM (P<0.05). There was also significant Se enrichment (P<0.001) in the longissimus thoracis muscle (177 vs. 477 ng g−1 DM) and organs: liver (474 vs. 1126 ng g−1 DM) and kidney (4956 vs. 5655 ng g−1 DM), Under such conditions, the human consumption of a piece of such meat or liver can provide a large part of the recommended daily Se intake, estimated between 30 and 57%.

Intensive pig breeding implies, among other things, the use of complete mixes in their diet in correspondence with the animals? age and purpose. In the course of a threeyear period (2007-2009) the accredited laboratory of the Department for Nutrition and Botanics of the Faculty for Veterinary Medicine, Univerisity of Belgrade, analysed 65 fodder mix samples from the territory of Serbia intended for the diet of all categories of pigs, namely: 6 samples of complete mixes for the diet of pregnant sows and gilts, 9 samples of complete mixes for the diet of nursing sows and boar, 4 samples of complete mixes for enhanced diet of piglets, 13 samples of complete mixes for piglets in programme I up to 15 kg, 12 samples of complete mixes for piglets in programme II from 15-25 kg, 10 samples of complete mixes for growing pigs in fattening programme I from 25-60 kg, and 11 samples of complete mixes for pigs in fattening programme II from 60-100 kg. The analyses covered the contents of the elementary nutritive matter and the obtained results were compared with the quality conditions prescribed under the Regulations on the quality of animal feed (Official Gazette of the Republic of Serbia No. 41/09). It was established that there were certain deviations with regard to the values presented in the Regulations on the quality of animal feed (Official Gazette of the Republic of Serbia No. 41/09) in the average protein content in complete mixes for piglet diet II, 15-25 kg (17.89?1.19%) and in the mixes for growing pig diet II, 60-100 kg (13.95?0.53%). The established average fat content was lower in the mixes for enhanced piglet diet (5.99? 0.72%) and in mixes for piglet diet I, up to 15 kg (4.95?1.41%). A higher average cellulose content (4.08?0.73%) was established in mixes for enhanced piglet diet. Furthermore, significant differences from the values prescribed under the Regulations were established in certain samples. The established differences in the chemical composition of certain samples of the examined mixes without a doubt indicate the need for constant and multilevel monitoring of raw materials and finished products in order to preserve health and to ensure the best possible utilization of the production potential of animals.

The aim of the study was to determine technological and consumption quality of some offal components obtained from Pulawska and Polish Landrace fattening pigs, and to analyse the eating quality of the offal products. The study material consisted of 100 fattening pigs: Pulawska (PUL) and 50 Polish Landrace (PL) pigs. The offal components were analysed for physical traits, chemical composition and energy value. Offal products were made from the offal and their physical, chemical and organoleptic parameters were evaluated. Our study showed that breed had a significant effect (p ≤ 0.05) on pH45 of the tongue, heart (PUL > PL), lungs and kidneys (PUL < PL), and on the fat content of the tongue, heart (PUL > PL), liver and kidneys (PUL < PL). A highly significant effect of breed (p ≤ 0.01) was observed for protein content of the lungs, liver (PUL < PL) and kidneys (PUL > PL), for collagen content of the kidneys (PUL < PL) and liver (PUL < PL), and for energy value (p ≤ 0.01) of the heart (PUL > PL) and liver (PUL < PL). Moreover, our results indicate that the organoleptic quality of the evaluated offal products was higher for Pulawska than Polish Landrace pigs, in particular with regard to consistency (p < 0.05) and flavour (p < 0.01) of the liver sausage.

Fattening Pigs

A co-ordinated trial has been carried out at twenty-six centres to compare the effects of three practical rations on performance and carcass quality of fattening pigs. The simplest of these was the ‘Shinfield ration’ (SR) and this was compared with the more elaborate National Pig Progeny Testing Station rations, the ‘old’ ration (OPT) as used until January 1963 and the ‘new’ ration (NPT) as used since January 1963.The OPT ration was significantly worse than the SR and NPT rations in respect of growth rate and food conversion. The simpler and cheaper SR ration did not differ significantly from the NPT ration. Ration differences were not significant for any carcass measurements.

The aim of this study was to investigate the effects on meat quality of crossbred bulls finished in a feedlot when some corn is replaced by glycerin and essential oils (EO) are added to the diet. Thirty bulls weighing 311 kg ± 28.8 kg (22 ± 2 months old) were randomly assigned to one of three diets: CON – Control (diet without glycerin and EO); GLY – 16.1% glycerin in dry matter (DM); and GEO – 16.1% glycerin in DM and EO (cashew: Anacardium occidentale; castor: Ricinus communis) at 442 mg/kg DM consumed. The bulls were kept in a feedlot for 115 days and slaughtered at an average weight of 467 ± 27.9 kg (25 ± 2 months old). The bulls were fed on sorghum silage, cracked corn, glycerin, soybean meal, urea, limestone, and mineral salt. Replacing corn with glycerin plus EO adding to the diet had no effect on the fat thickness, Longissimus muscle (LM) area, marbling, texture, colour, Warner–Bratzler shear force, or chemical composition of the LM. The fatty acid composition in the LM was similar among the diets, except for percentages of myristic and margaric acids. The diets had no effect on the percentage of saturated and polyunsaturated fatty acids. Animals fed on glycerin had a lower ratio of n-6 to n-3 in the LM when compared with the CON diet. Partial replacing of corn with glycerin and EO improved meat flavour, tenderness, and the preference of consumers. Corn may be replaced by glycerin to a 15% level of DM without any detrimental effect on the carcass characteristics or the chemical composition of the LM.

Fattening Pigs

Meat is a very rich and universal source of nutrients. The primary importance of meat is based especially on protein content. Optimum slaughter weight has influence on the basic chemical composition of meat. Fattening pigs were classified by their weight into three groups before the slaughter day. The highest content of proteins and water was found in the part of ham and shoulder in the group of animals at 100-110 and 111-120 kg of live weight, respectively, while the lowest content was found in the part of neck in animals at 121-130 kg of live weight. The highest content of intramuscular fat and mineral substances was in animals at 121-130 kg (neck and loin), while the lowest content was in animals at 100-110 kg live weight (ham). The pH values were within the optimum limits (5.33 - 5.77). Differences between the groups for the values of proteins content, mineral substance and pH values were statistically highly significant (p<0.05; p<0.01), while for the contents of water and intramuscular fat there were no differences (p>0.05) between the groups.

Fattening Pigs

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 cold-pressed 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.;

Commercial No. 1 Candle rapeseed (canola) (Brassica campestris) was prepress solvent extracted and heated to 105 °C at the desolventizing step (control meal). Samples of the canola (low glucosinolate) meal were also treated with ammonia or steam or both at the desolventizing step. The meals were analyzed chemically and subsequently fed to 70 growing pigs in a factorial experiment. Digestibility of the meals was determined separately. Ammoniation increased the crude protein (% N × 6.25) concentration from 39 to 42%, decreased the proportion of alkaline soluble nitrogen and increased the available lysine level. Both ammonia and steam reduced glucosinolate concentrations but usually at least half the glucosinolates remained after any treatment. Compared with a soybean meal control diet, diets containing 10% treated canola meals did not affect daily gains, feed intakes or feed:gain ratios when fed to pigs. Ammoniation had little effect on crude protein digestibility of canola meal but, in combination with steam, reduced the energy digestibility. Based on these results, there appeared to be no advantage in ammoniating canola meal as a means of improving its nutritional quality in swine diets.

1. A co-ordinated trial has been carried out at twenty-two centres to compare the value of wheat, crushed or ground, with that of fine wheat offal (weatings) when fed in equal amounts in the rations of growing pigs.2. Pigs fed the wheat rations grew faster (8·7% improvement for crushed wheat, 6·3% for ground), had. more efficient food conversion (9·0 and 6·5%) and yielded heavier carcasses for a given final live weight (1·4 and 1·3%) than pigs fed weatings but were fatter at the shoulder (5·6 and 7·5%) and the loin (11·2 and 13·1%); all these effects were highly significant. Differences in length of carcass were not significant.3. Improvements in growth rate and food conversion were significantly greater with crushed wheat than with ground wheat. None of the other differences between crushed wheat and ground wheat was significant.4. An economic appraisal has been made which shows that, on the basis of certain assumptions, the feeding of wheat would have resulted in higher profit per year than the feeding of weatings under the price structure and system of grading prevailing during the period of the experiment.5. Changes in the price structure (average price of bacon pigs, differentials between grades and cost of wheat and weatings), in the average quality of the carcasses (length of the carcass and fat at the shoulder and loin) and in the size of treatment effects on food conversion, all have a substantial effect on relative profits. The appraisal suggests, however, that feeding wheat would be more profitable than feeding weatings when the above changes were extremely severe.
