Abstract. In the present study, the effect of sea buckthorn pomace (SBP) supplementation (concentrations of 0, 4, 8 and 12%; intervention duration of 4 or 8 weeks) on finishing performance, meat quality parameters, and fatty acid and vitamin C contents in muscle of German Landrace pigs was assessed. Supplementation with SBP did not negatively affect growth performance and slaughter quality traits of pigs. The overall meat quality including nutrient composition (protein, fat, water), meat colour and pH value was not changed. Surprisingly, the fatty acid profile of longissimus muscle was only slightly affected by different SBP concentrations and intervention durations. Highest amounts of n-3 fatty acids (28 mg/100 g muscle) were measured in pig muscle which had received a 12% SBP-supplemented ratio with over an intervention period of 8 weeks. The contents for vitamin C of longissimus muscle of pigs of the control group and SBP supplementation groups varied between 24.0 and 28.7 μg g−1 fresh muscle, and were not diet affected. Other diet compositions and possibly changes in SBP during the manufacturing process of diet pellets should be included in investigations to develop an application-oriented concept of SBP as a supplement for pig feeding.

The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the experimental group than in the control group (p < 0.05). However, drip, cook and thaw losses were not influenced by dietary treatment (p > 0.05). A significant increase in protein, Fe, Zn, Na, P and a significant decrease in lipid, Cu and Cr contents was exhibited in experimental group relative to control group (p < 0.05). The proportion of stearic acid and saturated fatty acids was significantly (p < 0.05) reduced, whereas linoleic acid and polyunsaturated fatty acids contents were significantly (p < 0.05) increased in breast and thigh muscles of fed the experimental diet. We concluded that additive supplementation of the diet with probiotics and Yucca schidigera extract could improve meat quality.

In the present study, we tested the hypothesis that feeding sunflower oil (SFO) containing about 70% linoleic acid would increase conjugated linoleic acids (CLA) content of beef and that the increased CLA levels would improve meat shelf life. Two feeding trials were conducted to determine the effect of SFO supplementation on beef production , carcass characteristics and meat quality parameters. In addition, the visual aspects of beef quality in retail display as influenced by dietary vitamin E were compared with that of the increased CLA derived from dietary SFO. In exp. 1, 72 finishing steers (465 ± 9 kg) were individually fed one of four dietary treatments: an unsupplemented control finishing diet, the control diet supplemented with 6% SFO, 500 IU head-1 d-1 vitamin E or a combination of 6% SFO and 500 IU head-1 d-1 vitamin E for 95 d. Data from in vitro gas production from the diets indicated that oil inclusion reduced rate and lag time prior to initiation of gas production. Dry matter intake (DMI) declined (P < 0.05) due to dietary treatments without affecting average daily gain or feed conversion efficiency. Meat from steers fed all supplements was less red, more discolored and less acceptable after 2 d storage in a display case. In exp. 2, 40 steers (412.5 ± 11 kg), in individual pens, were used in a second completely randomized design experiment to evaluate the effect of supplementation of steam-rolled barley based finishing diets with 0, (CON) 3 or 6% SFO or 500 IU head-1 d-1 vitamin E on performance, carcass, meat characteristics, and fatty acid composition of beef. No difference (P > 0.05) in final liveweight, DMI, average daily weight gain (ADG) and feed efficiency (FE) of steers fed diets was found. Carcass grade fat was higher (P < 0.05) in steers fed the 6% SFO diet than the other diets. Retail acceptance score of meat obtained from steers fed 6% SFO was higher than from steers fed other diets (P < 0.05). In both experiments, the fatty acid composition of the meat indicated that C16:0 and C16:1 fatty acid levels were lower (P < 0.05) while C18:2 was higher (P < 0.05) in longissimus muscle of steers fed 6% SFO than the other diets. CLA content in fat from longissimus muscle was higher in steers fed the 6% SFO than control diets (3.5 vs. 3.0 mg g-1 in exp. 1 and 3.5 vs. 2.0 mg g-1 in exp. 2; P < 0.05). Hence supplementing feedlot diets with SFO for up to 108 d can increase CLA composition of beef. Positional distribution of fatty acids indicated that the majority of the CLA was in the sn-2 position of the triacyglycerol molecule. Key words: Beef cattle, conjugated linoleic acid, fatty acids, meat quality, sunflower oil, vitamin E

AbstractThis study evaluated the effects of a diet containing yellow mealworm (Tenebrio molitor L.; TM) larva meal on quality parameters (pH24, color and drip losses), proximate composition and fatty acid (FA) profile of meat from free-range chickens. A total of 140 medium-growing hybrid female chickens were free-range reared and randomly allotted to two dietary treatments: a control group and a TM group, in which TM meal was included at 75 g kg−1 as fed in substitution of corn gluten meal. Each group consisted of five pens as replicates, with 14 chicks per pen. At 97 days of age, ten birds (two birds/pen) from each feeding group were slaughtered at a commercial abattoir. Quality parameters and proximate composition of breast and thigh meat were not affected by treatment. The effects of dietary TM larva meal on the FA profile of thigh meat were negligible. Breast meat from TM-fed chickens showed higher oleic and α-linolenic acid percentages as well as lower atherogenicity and thrombogenicity indexes. In conclusion, this study demonstrated that TM inclusion in diets for free-range chickens did not prejudice meat quality traits. The obtained results confirm that TM can be considered a promising insect protein source for the poultry feed industry.

Abstract. The potential of goats to produce a high-quality meat is mainly reflected in their healthy fats, low calorie intramuscular fats, saturated fats, and, especially, their high ratios of unsaturated (UFA) and saturated (SFA) fatty acids, as well as hypocholesterolemic and hypercholesterolemic fatty acids. The aim of this study was to collect and compare meat quality parameters for domestic Balkan, Alpine and Saanen goats of the same age. Samples for all tests were taken from musculus gluteus superficialis. Chemical composition, pH value, fatty acid composition, content of volatile compounds, color and overall sensory quality (appearance, texture and smell) were determined. In chemical composition, moisture, fat, protein and ash varied significantly between each of the examined groups as opposed to pH values. Furthermore, among all the examined groups a significant difference was found for fatty acids and volatile compounds. Determined ratio of polyunsaturated fatty acids (PUFAs) to SFAs was 0.089, 0.085 and 0.071 for Balkan, Alpine and Saanen goat meats, respectively. Regarding that ratio, Saanen goat meat had the most favorable characteristics. Saanen goat meat showed the highest nutritional value. On the other hand, Balkan goat meat had the lowest intramuscular fat content. Measurements of the meat color from all three groups, as well as overall acceptability, showed significant differences between breeds. Obtained results point to the impact of breed on chemical composition and fatty acid profile of goat meat.

The quality of goat meat has recently become an important aspect in the marketing of goats in Serbia. The aim of this study was to compare some goat meat quality parameters of various races and to determine the differences between them. Goat breeds were Balkan goat and Serbian White goat, both female in the age of four years. Analysis of quality parameters: chemical composition (moisture, protein, total fat, ash,), pH value, fatty acids, amino acids, microelements content, tenderness, cooking loss and colour measurements were done. Statistically significant difference was found between the samples of two groups of goat meat (P <0.05) in relation to: live weight (kg), water (%), fat (%), protein (%), ash (%), among 11 of 15 tested fatty acids, amino acid leucin, sensory examination of fresh meat for the palpatory evaluated firmness and in the content of copper and zinc. Statistically significant differences between the groups did not existed regarding the pH value, fatty acids eicosenoic, cis-heptadecenoic, t-elaidic, t-linolelaidic and amino acids alanine, arginine, aspartic acid, cysteine, glutamic acid, glycine, histidine, isoleucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine. Also there was no statistically significant difference in instrumental testing of the meat color, sensory evaluation of surface color, visual evaluated structure, olfactory evaluated odor and iron and manganese. These results suggest that the race of animal has an impact on meat quality.

The purpose of this study was to investigate the effects of different levels of mealworm (Tenebrio Molitor) larvae meal in Japanese quail (Coturnix coturnix japonica) diets on performance, egg quality, yolk color, and yolk fatty acid composition. A total of forty-eight, 14 weeks-old laying quails were used with 4 replicates in control (basal diet), mealworm larvae meal (MLM) 2% or 4 % treatment groups. Results showed that independently of inclusion level dietary MLM did not affect performance and egg quality parameters. However, color values (L*, a*, b*) of egg yolk changed with the inclusion of both levels of MLM to diet (p<0.5). Outcomes also displayed dietary MLM altered the fatty acid composition of egg yolk dependably the additional level (p<0.5). Diets containing 2 and 4 % MLM did not affect total saturated fatty acid (ƩSFA) content, however, increased total monounsaturated fatty acids (ƩMUFA) (p<0.5). Both supplemental levels of dietary MLM decreased significantly the total polyunsaturated fatty acids (ƩPUFA) of the yolk compared to the control group (p<0.5). According to outcomes of this study, MLM may use in safe as feed material instead of soybean meal at levels of 2 or 4 % without effect on performance parameters in laying quail diets.

The study was designed to evaluate the effect of diet supplementation with linseed on the carcass characteristics, meat quality and oxidative stability as well as the composition of the fatty acids in M. longissimus lumborum et thoracis (MLLT) and the backfat of fattening gilts. A total of 40 animals were used, 20 in the experimental and 20 in the control group. The results indicate that gilts fed with the control feed mixture (C) showed a higher (P &lt; 0.05) content of intramuscular fat and backfat as compared to the experimentaL group (L) of gilts. A higher drip loss (P &lt; 0.001) was recorded in the L group as same as higher pH<sub>45</sub> and pH<sub>24</sub> values (P &lt; 0.01). The fatty acid profile analysis in the MLLT showed that the content of the MUFA (monounsaturated fatty acids) was lower (P &lt; 0.01) in the L group than in the C group of the animals and also showed a higher (P &lt; 0.01) content of the PUFA (polyunsaturated fatty acids) in the L group. The content of the n-6 and n-3 PUFA was higher (P &lt; 0.001) in the L group. The ratio of the n-6/n-3 PUFA was significantly lower (P &lt; 0.001) in the L group. The PUFA/SFA (saturated fatty acids) ratio was more favourable in the L group of gilts (P &lt; 0.01). The results of the fatty acid profile analysis in the backfat proved the higher (P &lt; 0.05) content of the UFA (unsaturated fatty acids) in the L group, while the content of the MUFA was lower (P &lt; 0.001) in the L group. The total content of the SFA was lower (P &lt; 0.05) in the L group.

The aim of the study was to assess the influence of the addition of fish raw materials (roe or fish meat) on the quality and nutritional value of pork pâtés. The control group (n = 4) consisted of pork pâtés, I experimental group (n = 6) of pâtés with 20% addition of roe (perch and pike), and II group of pâtés with 20% addition of fish (perch and pike meat) (n = 6). The pâtés’ pH, color, and profiled texture analysis were instrumentally measured and water, protein, fat, ash, and fatty acid content were determined by reference methods. To assess the oxidative stability of lipids the measurement of peroxide number, thiobarbituric acid reactive substances and content of conjugated dienes and trienes was used. The degree of fat hydrolysis was determined on the basis of acid value. Sensory analysis was carried out using the scaling method, taking into account 12 unit quality characteristics. Products with roe and meat contained less fat (accordingly 15.9% and 14.1%) and showed lower calorific value (accordingly 225.6 and 208.6 kcal/100 g) compared to pork pâtés (20.2% of lipids, 267 kcal/100 g). Moreover, the addition of fish raw materials improved the index of nutritional quality for protein (from 3.2 to 3.9) and beneficially reduced the nutritional index for fat (from 2.2 to 1.9). Fish constituents modified, to a certain extent, the color, texture, and sensory properties of pâtés, while maintaining full acceptability in consumer assessment. The addition of fish roe significantly increased the healthful quality by improving the fatty acid profile of pâtés, in which the significantly highest content of n-3 fatty acids, including eicosapentaenoic and docosahexaenoic acids (accordingly 252.21, 43.17, and 107.94 mg/100 g product), as well the highest concentration of saturated branched chain fatty acids were determined (18.75 mg/100 g product).

We evaluated the effects of a rumen-protected microencapsulated supplement from linseed oil (MO) on ruminal fluid, growth performance, meat quality, and fatty acid composition in Korean native steers. In an in vitro experiment, ruminal fluid was taken from two fistulated Holstein dairy cows. Different levels of MO (0%, 1%, 2%, 3%, and 4%) were added to the diet. In an in vivo experiment, eight steers (average body weight = 597.1 ± 50.26 kg; average age = 23.8 ± 0.12 months) were assigned to two dietary groups, no MO (control) and MO (3% MO supplementation on a DM basis), for 186 days. The in vitro study revealed that 3% MO is an optimal dose, as there were decreases in the neutral detergent fiber and acid detergent fiber digestibility at 48 h (p < 0.05). The in vivo study showed increases in the feed efficiency and average daily gain in the 3% MO group compared to the control group on days 1 to 90 (p < 0.05). Regarding meat quality, the shear force produced by the longissimus thoracis muscle in steers from the 3% MO group was lower than that produced by the control group (p < 0.05). Interestingly, in terms of the fatty acid profile, higher concentrations of C22:6n3 were demonstrated in the subcutaneous fat and higher concentrations of C18:3n3, C20:3n3, and C20:5n3 were found in the intramuscular fat from steers fed with 3% MO (p < 0.05). Our results indicate that supplementation with 3% MO supplements improves the growth performance and meat quality modulated by the omega-3 fatty acid content of meat in Korean native steers.

The supplementation of rumen bypass fat (RBF) has remained one of the preferred approaches used to decrease undesirable saturated fatty acids (FA) and increase beneficial unsaturated FA in the meat. This study was planned to evaluate the influences of rumen bypass fats on meat quality, fatty acid and metabolic profiles in male Dorper sheep (n = 36) with 24.66 ± 0.76 kg (mean ± standard error) initial body weight. Treatment comprised a basal diet (30:70 rice straw to concentrate) with no added RBF as a control (CON), basal diet with prilled fat (PF), basal diet with prilled fat plus lecithin (PFL) and basal diet with calcium soap of palm fatty acids (CaS). The findings revealed that cooking loss, drip loss and shear force in longissimus dorsi (LD) muscle were not affected by RBF supplementation, while meat pH was significantly higher in the CaS on aging day 1. However, the diet supplemented with prilled fat and lecithin modified the meat’s fatty acid profile significantly by increasing unsaturated fatty acids and decreasing saturated fats. The relative quantification of the major differentiating metabolites found in LD muscle of sheep showed that total cholesterol, esterified cholesterol, choline, glycerophosphocholine and glycerophospholipids were significantly lower in CaS and PFL diets, while glycerol and sphingomyelin were significantly higher in CaS and PFL diets. Most of the metabolites in the liver did not show any significant difference. Based on our results, the supplementation of protected fats did not have a negative influence on meat quality and the meat from Dorper sheep fed prilled fat with lecithin contained more healthy fatty acids compared to other diets.
