The aim of this experiment was to investigate total tract apparent digestibility of energy and nutrients in pigs previously fed a diet supplemented with 20% grass meal (high-fibre diet). Thirty-six pigs of 25 kg BW were randomly allotted to 4 treatment groups. The pigs were fed ad libitum a basal diet (B) or a high-fibre diet (HF) during the entire experiment (control group C and group HF105, respectively), or a high-fibre diet up to 50 or 80 kg BW (groups HF50 and HF80, respectively) followed by diet B up to 105 kg BW. Diet B contained (in g.DM-1): crude protein, 212; crude fibre, 43; total lysine, 11.1 and gross energy, 18.0 MJ. Diet HF was formulated by mixing diet B with 20% of grass meal and contained (in g.DM-1): crude protein, 191; crude fibre, 85; total lysine, 9.1 and gross energy, 18.3 MJ. The apparent digestibility of energy and nutrients was measured within a short time after exchanging diet HF for diet B (at approximately 55 and 85 kg BW) using an indirect method (with chromic oxide as an indicator).The apparent digestibility of energy and nutrients of diet HF was on average approximately 10% lower (P<0.01) than in diet B. Consequently, the energy value of diet HF was 1.67 MJ DE lower than in diet B. The digestibilities of energy and nutrients of diet B fed after the diet with a high fibre content (HF50 and HF80 groups) were not affected by the preceding diet, with the exception of the digestibility of crude fibre, NDF and ADF fractions, which were digested approximately 2.0% better, and ether extract, which was digested 3.2% worse (non significant difference). When the digestibilities of energy and nutrients in pigs weighing 55 and 85 kg were compared, however, it was found that heavier pigs digested (P<0.05) energy and protein (average by 1.0 and 1.9%) and crude fibre, NDF and ADF (by 8.2, 2.7 and 4.5%, respectively) more efficiently than pigs at 55 kg BW. Consequently, the energy value of diets fed to pigs at 85 kg BW was greater by 145 kJ.DE-1 (P>0.05) than at 55 kg BW.

Wpływ rasy świń na zawartość kwasów tłuszczowych w wybranych tkankach został określony na 16 loszkach rasy wielkiej białej polskiej (wbp) oraz mieszańcach ♂duroc x ♀(wielka biała polska x duńska zwisłoucha). Od 70 do 110 kg masy ciała (m.c.) zwierzęta otrzymywały paszę, w której 9% energii metabolicznej (EM) pochodziło z mieszaniny olejów lnianego (2,0%), rzepakowego (0,5%) i rybiego (0,5%), wprowadzającej do paszy kwasy C18:3 n-3 (ALA), C20:5 n-3 (EPA), C22:5 n-3 (DPA) i C22:6 n-3 (DHA). Świnie ubito przy około 110 kg m.c. Z mięśnia longissimus dorsi (MLD) i z tłuszczu podskórnego (TP) pobrano próby, w których określono zawartość ekstraktu eterowego (%) oraz kwasów tłuszczowych (g/100 g tkanki). Świnie obydwu analizowanych grup charakteryzowały się podobnymi wynikami produkcyjnymi i otłuszczeniem (grubością słoniny i zawartością tłuszczu podskórnego), różniły się natomiast zawartością tłuszczu śródmięśniowego. MLD świń mieszańców zawierał więcej (P≤0,01) kwasów SFA i MUFA oraz PUFA (w tym ALA, EPA, DPA i DHA) niż MLD świń rasy wbp. Natomiast w TP loszek mieszańców było mniej (P≤0,05) MUFA (w tym C16:1 n-7 i C18:1 n-9) oraz więcej (P≤0,05) PUFA (w tym PUFA n-3) w porównaniu z TP loszek rasy wbp. Tłuszcz śródmięśniowy obydwu grup miał podobną proporcję kwasów PUFA/SFA (średnio 0,44), ale proporcja PUFA n-6/PUFA n-3 (Σn-6/Σn-3) była znacznie mniejsza, a więc korzystniejsza, u świń mieszańców niż u rasy wbp (3,73 vs. 5,80; P≤0,01), co wynikało z wyższej zawartości PUFA n-3 w MLD tych świń. Natomiast tłuszcz podskórny u obydwu grup świń miał podobną proporcję kwasów Σn-6/Σn-3 (średnio 2,83), ale proporcja kwasów PUFA/SFA była większa (P≤0,05) u loszek mieszańców (0,58) niż u wbp (0,50).

The effect of breed on fatty acid (FA) content of the selected tissues of the pigs fed a diet enriched in omega-3 FA was determined in sixteen Polish Large White (PLW, n=8) and ♂Duroc x (♀Polish Large White x ♂Danish Landrace) (n=8) pigs. From 70 to 110 kg body weight (BW) the animals were fed a diet in which 9% of ME originated from energy of oil mixtures: 2.0% linseed, 0.5% rapeseed, 0.5% fish, which introduced to the diet C18:3 n-3 (ALA), C20:5 n-3 (EPA), C22:5 n-3 (DPA) and C22:6 n-3 (DHA) acids. The pigs were slaughtered at approximately 110 kg BW. The Musculus longissimus dorsi (MLD) and subcutaneous fat (ST) samples were collected for analysis of extract ether (%) and FA (g per 100 g of tissue) content. The analyzed breeds had a similar performance and backfat thickness, but they differed in the intramuscular fat content. MLD of crossbred pigs had higher content of SFA, MUFA and PUFA (including ALA, EPA, DPA and DHA) than PLW pigs, whereas subcutaneous fat of crossbred pigs had lower content of MUFA (including C16:1 n-7 and C18:1 n-9) and higher content of PUFA (including n-3 PUFA) than PLW pigs. Intramuscular fat of both breeds had similar ratio of PUFA/SFA (average 0.44), whereas the ratio of n-6 PUFA/n-3 PUFA (Ʃn-6/Ʃn-3) was lower (more favorable) in crossbred than PLW pigs (3.73 vs. 5.80). This was caused by the higher n-3 PUFA content in MLD, which was related to the higher intramuscular fat content in crossbred pigs. Moreover, crossbred pigs had more favorable ratio of PUFA/SFA in subcutaneous fat than PLW pigs (0.58 vs. 0.50), whereas the ratio of Ʃn-6/Ʃn-3 was similar in both pig breeds (average 2.83).

Określano zależności między składem chemicznym mięśni a kruchością mięsa loszek w wieku od 90. do 168. dnia życia. Skład chemiczny mięśni zmieniano ograniczając świniom pobranie energii i białka (grupa P i Pad) lub samego białka (grupa B) do 118. dnia życia. Od 119. do 168. dnia życia zwierzęta grup P i B karmiono tak jak świnie grupy kontrolnej (K), a świnie grupy Pad do woli. Zwierzęta ubito w 118. i 168. dniu życia. Pobrano i zważono Musculus longissimus dorsi i Biceps femoris. Oznaczono skład chemiczny i kruchość mięsa (wartość shear force) w 118. i 168. dniu życia oraz obliczono korelacje pomiędzy tymi cechami w 168. dniu życia świń. Czynnik doświadczalny nie wpłynął na zawartość białka w mięśniach w żadnym z badanych okresów. W 118. dniu życia mięśnie świń grup P, Pad i K zawierały podobną, a w grupie B większą (p>0,01) ilość tłuszczu. Kruchość mięsa świń grup P, Pad i B była gorsza (p<0,05) niż zwierząt grupy K. W 168 dniu życia mięśnie świń grup B i Pad zawierały więcej (p<0,01), a w grupie P mniej (p<0,01) tłuszczu niż świnie K. Kruchość mięsa nie różniła się między grupami. Korelacje między kruchością mięsa a składem chemicznym mięśni były większe dla zawartości białka niż tłuszczu (−0,50 vs. 0,08, odpowiednio).

The relationship between chemical composition and tenderness of meat was investigated. Restriction of energy and protein (group P and Pad) or only protein intake (group B) from 90 to 118 days of life was applied. Next, until 168 days of life, P and B pigs were fed similarly to K pigs, but Pad pigs ad libitum. Pigs were slaughtered at 118 and 168 days of life. Musculus longissimus dorsi and Biceps femoris were separated. At each slaughter age, chemical composition and tenderness of meat (shear force) were determined. Correlations between these features at 168 days of life were determined. The meat protein content did not differ among groups in any of the investigated periods. At 118 days of life, the muscles of P, Pad and K pigs contained similar, but of B pigs, higher (p<0.01) amounts of intramuscular fat. Tenderness of meat of P, Pad and B pigs was worse (p<0.05) than of K pigs. At 168 days of life, the musclesof B and Pad contained higher (p<0.05) and of P pigs, lower (p<0.01) amounts of intramuscular fat compared with K pigs. Meat tenderness did not differ among groups of pigs. The correlations between chemical composition and tenderness of meat were significantly higher for protein than fat content.

The experiment was conducted to assess the influence of a moderate feed restriction during the growth period on overall performance, corporal traits and fatty acid composition in pig backfat in pigs raised under high environmetal temperatures. A hundred Large White x (Large White x Landrace) barrows with an average initial weight of 34.5 kg were randomly distributed, in pens (10 pigs per pen). Fifty pigs were fed ad libitum for 36 days (AL pigs) and another fifty were restricted by 25% of their ad libitum consumption during the same period (R pigs). During the subsequent re-feeding period (64 days) all pigs were fed ad libitum. The only diet used contained 13.4 MJ ME kg-1, 17% crude protein and 1.3% lysine. The minimum, maximum and mean average temperatures recorded during the feed restriction and post-restriction periods were, ºC: 21.5±1.2, 28.6±1.3 and 25.0±1.1, and 22.6±0.9, 31.2±1.0 and 26.9±0.9, respectively. Considering the whole study period, the average daily gain and average daily feed intake were higher (P<0.05) for AL pigs than for R pigs (840 vs 808 g and 2478 vs 2383 g), although the feed conversion ratio was not different (P>0.05) (2.95 vs 2.95 kg.kg-1). At the end of experiment, no differences for dorsal fat thickness and area and for longissimus dorsi muscle depth, width and area, measured at site of the last rib by means of a real-time ultrasound device, were found between experimental groups. The linolenic acid proportions of the subcutaneous fat outer and inner layer were higher in AL than in R pigs (P<0.05), while palmitic and saturated fatty acids total proportions of the subcutaneous fat inner layer were higher in R than in AL pigs (P<0.05).

Через III дней 39 супоросных свиноматок кормили смесями содержащими 12 или 14,7% переваримого белка. Суточный рацион был 1,5; 2,0; 2,5 или 3,5 кг групп получающих смесь с 12% белка, и 3,5 кг для группы с 14,7% белка. Девять холостых свиноматок кормлено 2,5 кг/сутки смесью с 12% белка. Химический состав тела нетто определили на 28 свиноматках в начале опыта и на всех свиноматках по оконьчании опыта. Суточные привесы тела, белка и жира у супоросных свиноматок увеличивались пропорционально к увеличению рационов (P < 0,01). Различие в суточных привесах тела и белка между супоросными и холостыми свиноматками зависило только от матки и её содержимого. Потребление бытовое энергии супоросных свиноматок было 490,6 kJ/кг 0.75, стоимость отложения белка было 54,3 kJ/г, а жира 57,3 kJ/г.

During 111 days of gravidity 39 gilts were fed diets containing 12.0 or 14.7% digestible protein. Feed intake was 1.5, 2.0, 2.5 or 3.5 kg of 12% and 3.5 kg of 14.7% protein diets per day. Nine non-gravid gilts uere fed 2.5 kg 12% protein diet per day. Body net chemical composition was determined on 28 gilts at the start of experiment and on all experimental animals at the end. Body mass, protein and fat gain in gravid gilts increased proportionately to the increase of feed consumption (P < 0.01). Differences in body mass and protein gain between gravid and non-gravid gilts were entirely connected with uterus and ita content. Daily maintenance requirement of gravid gilta was 490.6 kJ/kg 0.75 cost of protein deposition was 54.3 and fat 57.3 kJ/g.

Pigs of Pietrain (P) and Polish Synthetic line of 990 (S) were slaughtered at 25, 70, 90, 110 and 130 kg BW and the chemical composition of musculus longissimus dorsi and its fatty acid profiles were determined. The Pietrain pigs were characterised by lower (P<0.01) concentration of intramuscular fat, total SFA (P<0.05) and MUFA (P<0.01) than pigs of the synthetic line 990 at each BW (P<0.05).Simultaneously the Pietrain breed were characterised by higher (P<0.01) concentration of all acids belonging to PUFA group. Concentration of total SFA increased (P<0.01) along with increased body mass of pigs. MUFA was similar at each investigated BW. However, in the case of Pietrain breed increasing concentration of the PUFA was observed till animals reached approximately 110 kg BW, while in Synthetic line only till 70 kg BW. Similar course was observed in the change of C18:2n-6 concentration. However, the concentration of C18:3n-3 decreased (P<0.05) along with the growth of the animals. The course of changes in concentration of C20:3n-6 and C20:4n-6 generally agreed with the course detected for total amount of PUFA. Activity of the Δ5 desaturase was higher (P<0.01) in the pigs of the synthetic line. The activity of the investigated enzymes did not differ between breeds. Activities of the elongase and Δ5 desaturase decreased during the growth of the pigs. Estimated values of the Pearsons’ correlation between body mass/age of the pigs and activity of investigated enzymes showed the opposite relationship between them. However, they were stronger and statistically more significant for the synthetic line of pigs.

The effect of fat content in primal cuts of pigs fed diet enriched in the mixture of linseed (2%), rapeseed (0.5%) and fish (0.5%) oils on healthpromoting properties of pork was investigated. Twenty-four crossbred (♂Duroc × ♀(Polish Large White × Danish Landrace)) pigs were fed an experimental diet restrictively from 60 to 105 kg of body weight. After slaughter the right-half carcass was dissected into neck, loin, ham, shoulder and belly. Based on the fat content in the Longissimus thoracis et lumborum muscle pigs were divided into two groups – with low intramuscular fat content (LMF; below 1.10%) and with high intramuscular fat content (HMF; above 1.10%). Meat from primal cuts was characterized with SFA (saturated fatty acids)/PUFA (polyunsaturated fatty acids) and n-6/n-3 PUFA ratios for meat with health-promoting properties according to WHO. Belly and neck of pigs from both groups, and loin and shoulder of HMF pigs met the European Union recommendations for human nutrition for products which are considered as either n-3 PUFA sources or products with high n-3 PUFA content. The particular fatty acids content is positively related with the fat content in primal cuts; however this effect is more pronounced in meat with a greater fat content
