The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P < 0.01), less protein (P < 0.01) and lighter meat (P < 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P < 0.01) and intramuscular fat (P < 0.01) and increased the content of hydroxyproline (P < 0.05). The CH bulls exhibited higher PUFA n-3 (P < 0.05) and lower MUFA (P < 0.05) compared to the CF, with the CH × CF being intermediate. The LCS diet enhanced the proportions of PUFA (P < 0.05) and PUFA n-3 (P < 0.001) and reduced MUFA (P < 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.

Abstract The aim of this study was to determine the effect of Virginia fanpetals (Sida hermaphrodita) silage on the fatty acid profile and the content of selected nutrients and vitamins in the Longissimus lumborum (LL) and Semimembranosus (SM) muscles of young bulls. Forty Polish Holstein-Friesian bulls aged 16 months were assigned to four dietary treatments (n=10) and were fed different types of silage during a 7-month fattening period. The proportion (g/kg dry matter) of silage in the diets was as follows: (1) grass silage (GS) (600); (2) Virginia fanpetals silage (VFS) (600); (3) VFS (300) and GS (300); and (4) VFS (300) and maize silage (MS) (300). Silage was supplemented with concentrate at 400 g/kg DM in each diet. The animals were slaughtered at the end of the fattening period. The intramuscular fat (IMF) of bulls fed GS had the highest (P<0.05) concentrations of n-3 polyunsaturated fatty acids (PUFAs) and linolenic acid (LNA), whereas the IMF of bulls receiving GS and VFS was characterized by the highest proportion of MUFAs, mostly oleic acid (C18:1 cis 9). In comparison with the LL muscle, the SM muscle contained less IMF (by 40%) with a more nutritionally desirable profile. The SM muscle was characterized by a more desirable mineral composition and a higher concentration of α-tocopherol.

Abstract. The study conducted a comparison of meat quality, fatty acid profile, and cholesterol amounts of longissimus dorsi (LD) and semitendinosus (ST) muscles of male lambs born to Turkish indigenous sheep breeds raised under intensive conditions. A total of 36 singleton male lambs were used as experimental animals of the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kıvırcık (KV), and Middle Anatolian Merino (MAM) pure breeds. All lambs were fed the same diet until they reached a target weight of 40 kg weight. After the feeding period, all lambs were slaughtered and LD and ST muscle samples were collected to determine meat quality traits, fatty acid profile, and cholesterol amounts. Although there were no significant differences between lambs in terms of the fatty acid profile of LD and ST muscles, KR lambs had a higher cholesterol content in both muscles in comparison with the lambs born to other breeds (p<0.05). While water-holding capacity, dripping loss, pH, color, dry matter, ash, and intramuscular fat values of ST muscles showed differences among breeds (p<0.05), dripping loss, pH, cooking loss, color, dry matter, ash, protein, and intramuscular fat values of LD muscles differed between breeds (p<0.05). The data of the current study indicated that meat quality characteristics and cholesterol contents of Turkish indigenous breeds showed differences, and these differences may be used for alternative lamb meat production for the consumer.

The effect of forage and breed of lambs on the fatty acid profile of intramuscular fat in m. longis-<br />simus lumborum (LL) and depot fat (SCF) above this muscle was investigated. The study was carried out in two replications on 36 Koluda sheep (KS) and Ile de France&times;KS (IF&times;KS) ram-lambs fattened intensively to 32&ndash;37 kg of body weight. Lambs were fed ad libitum the same concentrate mixture and different roughage supplements: grass hay in group C (control), field forage fed in a sheep house in group F, and pasture grazing (4 h/day) in group P. In the case of LL fat, the composition of fatty acids was found to deteriorate in lambs receiving forages compared to lambs from group C. Lambs grazed on pasture (P) had a higher content of LL fat (2.31 and 1.90% in P and C, respectively; P &le; 0.05), a higher proportion of SFA (42.1 vs 39.6%; P &le; 0.01), a similar proportion of MUFA, and a lower proportion of PUFA (10.4 vs 12.5%; P &le; 0.05). With similar content of depot fat, changes in the FA composition of SCF fat were observed in F lambs compared to group C. Compared to C lambs, SCF of F and P lambs contained less SFA (5.16% vs 46.8; P &le; 0.01 and 49.3%) and more MUFA (41.8% vs 45.6; P &le; 0.01 and 43.6%), with a similar proportion of PUFA and higher CLA content in group P (by 17.8%). The crossing of KS with Ile de France meat rams did not result in any differences in LL fat content, with a generally unfavourable effect on FA composition and health quality parameters calculated on this basis. The present study showed an unfavourable effect of supplemental forage in intensive fattening of lambs on the fatty acid composition of intramuscular fat. However, both variants of forage use had a generally favourable effect on the lipid profile of subcutaneous fat.

Entire Experiment

A total of thirty-four Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls with an average weight of 284 kg were included in the experiment and fed ad libitum two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal and lucerne silages) with different concentrations of dietary energy until slaughter at the target live weight of 600 kg. The CF bulls consumed more dry matter (DM) of feed daily than the CH bulls (<i>P</i> < 0.05) and gained weight less efficiently than the CH × CF and CH animals (<i>P</i> < 0.01) during the entire experiment. The killing-out percentage was lower in the CF than in the CH × CF and CH (<i>P</i> < 0.05). The CH bulls received a higher score for carcass conformation and a lower score for carcass fatness (<i>P</i> < 0.01) than the CF bulls, had lower proportions of kidney and cod fat (<i>P</i> < 0.01) than the CH × CF and CF bulls, and produced the highest percentage of high-priced meat (<i>P</i> < 0.05) and the lowest percentage of separable fat (<i>P</i> < 0.001). The bulls on the MS diet were younger than the others at the end of the experiment (<i>P</i> < 0.01), gained weight more rapidly (<i>P</i> < 0.001), consumed less DM (<i>P</i> < 0.001) daily, utilized nutrients more efficiently over the entire experimental period (<i>P</i> < 0.001), and had a higher proportion of internal fat than the LCS bulls. It can be concluded that purebred CH bulls were superior to the other breed groups in most of the traits observed. The intensive diet based on maize silage increased average daily gains, reduced the time needed to achieve the target slaughter weight, and improved the feed efficiency of bulls.

Much of the past research into gender effects on lamb meat quality has focussed on comparing ram lambs with castrated males, but more recent comparisons between ram and ewe lambs have yielded variable results. The objective of the current research was to compare meat quality parameters of M. longissimus lumborum (LL), and M. semimembranosus (SM) from pasture-fed Texel ram (n = 94) and ewe (n = 114) lambs slaughtered at an average age of 144 days in a commercial abattoir. After aging carcasses for between 7 and 9 days, LL and SM were significantly tougher (higher shear values) for ram compared with ewe lambs (P < 0.001). LL from rams had significantly lower intramuscular fat percentage, and higher moisture content than LL from ewes. Differences in LL intramuscular fat percentage or ultimate pH did not explain the sex effect on LL shear force when tested individually or together as additional covariates in the model. Ram SM was lighter in colour (higher L*) and had a higher cooking loss than that of ewes (P < 0.001). The correlations between some of the traits within and between muscles clearly differed between the sexes. Finishing ram lambs to the specifications used in this experiment resulted in meat with relatively minor, but statistically significant differences in quality relative to that from ewe lambs.

This research explores the possibility of using the fatty acid profiles of intramuscular fat to authenticate the origin of Retinta breed meat according to different feeding regimes based on the combined use of concentrate and grass or forage (GP, grass pasture; MC, medium concentrate; HC, high concentrate). Young bulls from GP (n=30) were reared on grass pasture and supplement with concentrate in controlled feeders; MC (n=30) and HC (n=15) were reared in farm buildings using 40 and 80% concentrate of total dry matter from diet, respectively. The stepclass function in R was used to perform a stepwise linear discriminant analysis including thirty fatty acids from intramuscular fat. Two fatty acids, 9c18:1 and 22:5 n-3 were selected as discriminators of the meat origin. Meat from the GP and MC was characterized by higher 22:5 n-3 (p<0.05), while HC meat showed higher 9c18:1 (p<0.05). The use of 9c18:1 and 22:5 n-3 fatty acids from intramuscular fat resulted in a correct assignation of 100% of beef samples to each of the feeding regimes. Therefore, in addition to serving as an effective tool for discriminating between feeding regimes in the origin of the beef, the fatty acid profile of intramuscular fat could help companies to check the authenticity of the meat origin.

AbstractThe effects of caponization on growth performance, carcass characteristics, meat quality and fatty acid profile of breast and drumstick of Mos and Sasso genotypes, reared in free-range production system were examined. A total of 47 birds of Mos breed (19 Castrated and 25 Entire) and 37 of Sasso X-44 (18 Castrated and 19 Entire) slaughtered at 32 weeks were used in this trial. The growth of broilers and the differences between genotypes and caponization effects were modelled by Weibull-growth equation. Capon’s growth was higher than that obtained by roosters and Sasso weight was greater than Mos results (P<0.05). For both genotypes the chemical composition of breast and drumstick cuts showed significantly higher values of intramuscular fat (P<0.0001) and lesser values of moisture (P<0.0001) in capons in comparison with intact ones. In Mos breed, capons exhibited significantly (P<0.0001) higher values of breast and drumstick luminosity and yellowness, as well as lower values of redness. Regarding Warner-Braztler test (WB), there were no significant differences (P>0.05) by caponization effect, but hardness measured using textural profile analysis was lesser in meat from capons. Finally castration of animals led to important modifications in the intramuscular fat because meat from capons showed significantly lower values for total saturated fatty acids (SFA) and higher polyunsaturated fatty acids (PUFA ). Nutritional indices were also more favorable in capon’s meat, so overall fatty acid profile of capons was desirable from the viewpoint of human nutrition.

The aim of this study was to determine the effect of inbreeding and sex on meat quality traits such as: acidity, colour, chemical composition and texture in New Zealand White and Belgian Giant Grey crossebred rabbits (n=84; 50♂:34♀). Two variants of crossing were used. Variant I - crossbred (F1) unrelated rabbits (RAB = 0) - received non - inbred rabbits (Fx = 0), variant II - crossbred (F1) related rabbits (full siblings RAB = 0.5) - received inbred rabbits (Fx = 0.25). After weaning at 35 days of age, animals were fed pellets ad libitum. Slaughter and dissection at 12 weeks of age were performed. After 45 min of slaughter pH loin (m. longissimus lumborum) and leg (m. biceps femoris), and the colour (L * - lightness, a * - redness, b * - yellowness) were measured. The results indicated that inbreeding had a significant effect on inerease of meat acidity in 45 min and after 24 h. Furthermore, the meat of inbred rabbits was a lightness and had smaller values of the redness and yellowness in 45 minutes and after 24 hours. Meat inbred animals contained less protein and ash, and more fat compared to meat non-inbred animals. Inbreeding did not affect significantly dry matter and water content in the meat. Texture parameters of inbred and non-inbred rabbits were similar. The level of inbreeding equal 25% affected negatively on meat quality traits such as acidity, colour and chemical composition. Sex does not differentiate the quality parameters of meat with the exception of yellowness in the 45th minute after slaughter.
