Recently, several concerns have been expressed on red meat quality and consumption. The aims of this study were to evaluate the influence of different breeding techniques and a prolonged post dry aging (PDA) maturation process on biomolecules level in raw buffalo meat. In the first experiment, two groups of animals were maintained with different space availability (15 vs. 10 m2/animal) for 90 days and biomolecules content was evaluated. In experiment 2, two diets (with or without ryegrass green forage) were used to assess the concentration of these biomolecules. Finally, in experiment 3, the meat of the animals that showed the highest content of biomolecules was chosen to assess the influence of the PDA maturation process. Buffaloes reared at 15 m2 showed a significantly (p < 0.05) higher content of the considered biomolecules compared with their counterparts. Similarly, buffaloes fed green forage showed higher content of biomolecules (p < 0.05) compared with the control group. The meat of the animals bred at 15 m2 and fed green forage showed a significant (p < 0.01) increase of biomolecules content during the PDA maturation process up to 60 days without influence microbiological profile in terms of total aerobic bacterial counts, yeasts, and molds. In conclusion, breeding techniques and PDA maturation system could enhance biomolecules levels in terms of quality, without affect health standards.

The influence of phytase added in diet for fattening chickens on the meat quality, was examined during the feed experiment. The experimental examinations were done on the chickens of Arbor Acres strain. There were 440 chickens in the experiment, divided into the 4 experimental groups considering the levels of mineral sources of phosphorus and phytase added into the diet. Control group K (110 chickens) dicalcium phosphate 2%, O-I group (110 chickens) monocalcium phosphate 1,4%; O-II group (110 chickens) dicalcium phosphate 1% + 0,1% phytase; O-III group (110 chickens) monocalcium phosphate 0,7% + 0,1% phytase. The feeding experiment lasted for 42 days. The chemical analyzes of white and red meat of experimental chickens that the meat of the chickens that gained phytase by diet with lower level of mineral source of phosphorus have more proteins and less fat phytase by diet (P<0,05).

The objective of the study was to determine the effects of probiotic bacteria Bacillus licheniformis and Bacillus subtilis on microbiological properties of feed mixtures and on the digestive tract content as applicable to production traits and carcass characteristics of fatteners. The experiment was performed on 83,838 fatteners from four successive (insertions) productions in two groups. From the seventy eighth day of age till marketing to the slaughter plant, the pigs were supplied with BioPlus YC probiotic (Chr. Hansen) in the amount of 400 g/t. The preparation contained a complex of probiotic bacteria Bacillus licheniformis DSM 5749, and Bacillus subtilis DSM 5750 spores in a 1:1 ratio. From the fourth insertion, after reaching a body weight of approximately 112 kg, 60 fatteners were selected from each group to measure carcass quality and half of them for meat quality evaluation. Moreover, microbiological analyses in feed and colon were performed. The study showed that BioPlus YC probiotics supplementation resulted in a significantly higher count of B. subtilis and B. licheniformis in the feed, a higher count of B. subtilis, B. licheniformis and LAB, as well as a lower count of Enterobacteriaceae, Enterococcus, Clostridium and Bacillus sp. in the mucosa and in the colorectal content of the test pigs. Our work has shown that supplementation with the BioPlus YC probiotic had a positive effect on the production traits of pigs mainly by reducing mortality (2.83%, p = 0.010), lowering feed conversion ratio—FCR (2.59 kg/kg, p = 0.013), better average daily gain—ADG (0.95 kg/day, p = 0.002) and shorter fattening period (77.25 days, p = 0.019) when compared to the control group (4.19%; 2.79 kg/kg; 0.89 kg/day; 92.8 days, respectively). The addition of the specific Bacillus bacteria did not influence carcass and meat characteristics of the test fatteners.

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.

In the last years several studies have investigated the strong relation between nutrition and immune response in the livestock production, particularly in dairy cattle and sheep. The aim of this study was to evaluate the effects of supplementation based on linseed, quinoa seeds and their combination on welfare, productivity and quality of meat from merinos derived lambs. 32 weaned lambs were divided into 4 experimental groups: quinoa (Q), linseed (LS) and combination of quinoa and linseed (LS + Q) that received the respective supplementation and control group (C) without supplementation. Lambs from all supplemented groups showed lower plasma urea, creatinine and cholesterol than control. Both linseed and quinoa supplementation enhanced the cell-mediated immune responses of lambs, furthermore, linseed supplementation resulted in the lowest level of cortisol secretion after handling, loading and transport. Meat from lambs supplemented with linseed and LS + Q showed the highest pH, at 1 and 3 h post-mortem, while, meat from all supplemented groups was more tender than meat from control. Results indicated that linseed and quinoa seeds supplementation can help the animal to cope with stressful events due to the close link between stress responses and the immune system and for improving meat quality in terms of better tenderness.

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.

Abstract Background: Colorectal cancer (CRC), defined as cancer of the colon or rectum, is one of the most frequently diagnosed cancers, and, according to the World Health Organisation database GLOBOCAN, it accounts for about 1.4 million new diagnoses annually worldwide. There is an association between the occurrence of colorectal cancer and non-modifiable risk factors, including age and hereditary factors, as well as with modifiable factors linked to the environment and lifestyle choices.Methods: The study included 800 patients, 400 diagnosed with colorectal cancer and 400 within the control group. The research was based on a clinical, direct, individual, structured, in-depth and focused interview. Assessment of activity and BMI was used according to WHO recommendations, as well as the expert system.Results: The average age of the patients was 64.53 ± 8.86 years, of the control group I - 59.64 ± 9.33 and the control group II - 57.5 (7.83). The association between the incidence of ulcerative colitis and the risk of colorectal cancer was clearly positive (p<0.001). Among obese subjects, the colorectal cancer risk was 1.27 (95% CI, 1.06-1.53) in comparison with non-obese subjects. The relative risk for current smokers was 2.17 (95% CI 1.79-2.66). Higher fat consumption and higher red meat consumption were also associated with the higher risk of colorectal cancer (p=0.01).Conclusions: Obesity, low physical activity, active and passive smoking and high salt and red meat consumption have been linked to a higher risk of colorectal cancer. The results give further evidence of the importance of maintaining a healthy lifestyle.

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

Context The water buffalo (Bubalus bubalis) is a valuable species in part because it is a multipurpose animal; its milk, horns and skin are all useful, and its meat is rich and nutritious. However, water buffalo meat still suffers many marketing restrictions. Aims The present study evaluated performance, ingestive behaviour, carcass characteristics and meat quality. Methods We examined the meat of 24 Murrah water buffaloes that weighed 287.8±1.8 kg and were divided into four groups that received 0, 250, 500 or 750 g/kg dry matter (DM) of a 3:2 blend of spineless cactus–cottonseed (henceforth, referred to as the blend) for 125 days in a completely randomised design. Key results The inclusion of the blend resulted in diets with increased moisture and crude protein intake at 250 g/kg inclusion and reduced intakes of non-fibrous carbohydrates and total digestible nutrients per kilogram DM, which led to an increased DM intake, but significantly lower (P&lt;0.001) final bodyweight, average daily gain, and hot carcass weight, thus resulting in a significantly lower (P&lt; 0.001) growth efficiency. Moreover, there was a reduction in the ammonia-nitrogen concentration and time spent drinking (P≤0.05). The ruminal pH and time spent feeding, chewing and defecating increased (P≤0.05), the fat content and colour parameters of the water buffalo meat increased, and the shear force decreased (P≤0.05) in response to the inclusion of the 3:2 blend of spineless cactus–cottonseed in the diet. The time spent on both rumination and urination, most of the physicochemical properties, and the consumer appeal of the meat, were not affected by the inclusion of the blend (P&gt;0.05). Conclusion The 3:2 blend of spineless cactus–cottonseed is not an effective replacement for corn bran and soybean meal in buffalo diets because, despite improving the rumen pH, the blend reduces the performance and carcass characteristics of the water buffalo. However, the fat content, coloration and softness of the meat improved, which is of commercial importance. Implications The inclusion of the spineless cactus–cottonseed blend in place of the high-concentrate diet did not affect the consumer appeal of the meat. The meat characteristics were scored as ‘like moderately’ (6–7 on a 9-point hedonic scale). On the basis of the scores of the panellists, all of the meats were well accepted.

ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.
