The composition of muscle fibers is influenced by animal breed or age. In our study we found differences in fiber diameter between sheep breeds. Lambs of a more primitive breed were characterized by smaller diameters of all fiber types. The study has shown that the diameters of muscle fibers in the examined muscles increase with age. It was also stated that the muscle type, animal genotype and body weight at slaughter influence the chosen meat quality attributes.

In this work, alpaca wool thickness and medullation characteristics were analyzed based on the animals' sex and color. The wool of females was thinner and had a lower medullation percentage than for males. The share of non-medullated fibers in the area up to 30 µm was also greater in the wool of females than for males. Light wool was thinner and had a lower degree of medullation than dark wool. The discontinuous and continuous medullated light fibers were thinner than those of dark fibers.

In an experiment the longissimus lumborum and gluteus medius muscles were collected from lambs of two genotypes to analyse physico-chemical traits, fatty acid profile, taurine, carnosine, and L-carnitine. Results showed a greater impact of the lamb’s genotype on physical traits of meat than on its chemical composition and content of bioactive components. Muscle type had an effect on meat colour; collagen content; fatty acid profile; and the amount of taurine, carnosine, and L-carnitine.

The research was carried out on lamb meat to determine the physicochemical characteristics and oxidative stability of lipids. The analysis was performed on fresh and 14 d aged longissimus lumborum and gluteus medius muscles. The meat aging determined all physicochemical features except protein and fat content. The tenderness of meat was better in muscles aged for 14 d. The muscles differed in the degree of lipid peroxidation in both fresh and aged meat.

Wet brewers grain (WBG) is successfully used in animal nutrition, especially in ruminants. The low cost of this fodder also has a positive impact on the economics of production. The aim of this study was to determine the effect of the addition of WBG to lamb feed on growth, slaughter value and meat quality. Lambs fed WBG were characterized by higher daily gains and better meat quality. The results indicate that WBG could be used in slaughter lamb production as a source of cheap fodder.

Milk produced by two non-dairy breeds, i. e., Żelaźnieńska and Wrzosówka sheep, maintained under the same nutritional conditions, did not differ in terms of the amount of basic components. Higher amounts of PUFAs n-3, a more favorable ratio of n-6/n-3 and a lower level of cholesterol were observed in milk of the more primitive breed (i.e. Wrzosówka). We suggest that non-dairy breeds can provide high-quality milk that can positively affect the carcass quality of lambs slaughtered at low weight.

The CAPN1 gene was selected as a target gene to identify single-nucleotide polymorphisms (SNPs) and see if SNPs significantly affect meat quality in Bali cattle. Three SNPs in the CAPN1 gene were associated with ultrasound marbling and intramuscular fat, pH, tenderness, meat color, and fatty acid in Bali cattle. The CT genotype differed significantly from those of CC and TT genotypes in the gene expression result. CAPN1 gene polymorphisms could be used as markers for meat quality in Bali cattle.

We compared the quality of beef in three muscles obtained from the carcasses of bulls of a local breed of Polish Red cattle and of typical Limousin beef originating from France and Poland. All animals were maintained by an extensive production system using year-round pasture and, additionally, bale grazing in winter season feeding. The beef of the local breed, with distinct attributes like a higher essential fatty acid content, proves to be suitable for producing high-nutritional-value beef.

This paper explains the influence of a sheep's lactation stage on the physical and chemical properties, hygienic quality and fatty acids in milk produced by Lacaune sheep kept in intensive breeding. A significant increase in the content of fat, protein, total dry matter and casein and a significant decrease in the content of lactose in the late stage of lactation were observed. Analysis of fatty acids in milk proved a decrease in C18:2n6, C18:3n6, n6 and n6/n3 ratios during lactation.

We present a novel study of the effect of bta-miR-33a on lipid metabolism in bovine mammary epithelial cells (BMECs). The correlation between bta-miR-33a and target gene ELOVL6 is also verified by a luciferase reporter assay. We show that bta-miR-33a directly inhibits the expression of ELOVL6 in BMECs, altering the mRNA expression of relative genes. This suggest that bta-miR-33a regulates lipid metabolism by targeting ELOVL6, which might be a potential molecular marker of milk fat composition.

Our research tried new ideas and measured the milk production performance of cashmere goats and found that the nutritional indicators of milk of Liaoning cashmere goats were excellent, laying a theoretical foundation for the future development of breeding to cashmere goats. At the same time, it also provides theoretical support for producers and can screen individual genotypes based on the experimental results during seed selection, thereby improving production performance to a certain extent.

Packaging methods (vacuum packaging and modified atmosphere packaging) allow for maintaining high-quality meat during a long period of storage (30 d) under refrigeration conditions. An interaction between the storage time, packaging method, and mesophilic aerobic bacteria and coliform counts was observed. Storage time affected the number of aerobic psychrotrophic bacteria, redness, pH, shear force value, and desirability of the meat's aroma and taste.

This study investigated the interactive effects of weather conditions, transportation time and loading density on carcass damages and meat quality traits of pigs. Pigs exposed to short transportation at low space allocation during hot weather conditions produced the lowest pork quality. Pigs exposed to short transportation at high loading density during cold weather conditions produced the highest pork quality. Hence, weather and transport conditions are of great importance for the pork quality.

The aim of this study was to assess the performance and meat quality of meat-type guinea fowl fed commercial diets under two different feeding programs similar to those for turkeys and broilers. Findings of the study suggest that these diets can be used in meat-type guinea fowl rearing without affecting the productive traits and meat quality. However, due to the lower price of chicken feed (due to lower protein content), its use seems to be more justified from an economic point of view.

Recently, consumers have been seeking natural and healthy products such as meat rich in polyunsaturated fatty acids, beneficial for health with decreasing the saturated fatty acids. Then, to enhance the meat quality, some nutritional strategies were considered such as using the residues of aromatic and medicinal plants. Then, the use of rosemary residues in lamb feeding increased the polyunsaturated fatty acid, n-6 and n-3 contents and reduced the saturation index in muscles and adipose tissues.

Here, we investigated the effect of sire line on growth performance and carcass traits of crossbred offspring under standardized environmental conditions. Pigs sired by a synthetic line showed benefits in fattening performance and Piétrain crossbreeds were characterized by a better carcass value. The synthetic line is preferable in terms of the number of fatting pigs per fattening place and year, while the Piétrain line provides increased leanness and carcass cuts.

We measured physical meat quality of a slow-growing broiler as an alternative to fast-growing broiler, and we used slatted floor housing and free-range production as alternatives to conventional deep litter. Taking into account genotype × housing system interactions for meat pH and shear force traits, a fast-growing broiler may be more appropriate for fully slated housing and a slow-growing broiler may be more suitable for a free-range housing system.

This study aimed to assess drip loss measurements in mutton taken by different methods (EZ and bag, BM) and their relationship with pH values and color. Mutton samples originating from 20 ewes of Istrian sheep were used to examine the effect of the method on drip loss after 24 and 48 h. EZ and BM method in mutton do not provide equivalent results for measuring drip loss. Comparisons of the results obtained with different methods should be avoided or at least performed with great precaution.

The aim of this study was to compare the chemical composition and fatty acid content of the muscle tissues of lambs and adult sheep. The results support the inclusion of dietitian-recommended mutton into the human diet and the promotion of the production of meat from adult animals as a high-value product. The sheep industry could benefit economically, particularly in countries where this meat type has not enjoyed a high standing in consumer preferences.

Carp is one of the most important fish in aquaculture. For future breeding programs, precise phenotyping is required. CT technology has been used to predict body composition in mirror carps. Back fat has proven to be a suitable parameter for predicting the fillet fat content. The volume calculation of back fat provides better results than a two-dimensional thickness measurement of back fat. The fillet yield can be predicted with moderate results by CT-based thickness measurements of the fillet.

In Spain, young bulls are slaughtered about 14 months. After slaughter, the carcasses remain in the slaughterhouse for less than 7 d. The present work collects this information and makes an attempt to analyse the response of the meat during the first 7 d of maturation to the oxidation of the fatty acids. Natural antioxidants in beef ensure fatty acid stability during first 7 d postmortem. Beef from pasture-fed meat includes a higher natural antioxidant content than grain-fed meat.

Wild boar meat can be used as a culinary meat, while lighter carcasses have better nutritional value. The carcass weight and the muscle of wild boars affected the physicochemical properties of the meat, causing differences in the water holding capacity, shear force, meat brightness, content of hem-dyes, protein, fat and water, thus changing the technological usability and nutritional properties of meat.

Goat breeds in Iran are various. People use goat products for food in addition to clothing. Among goat breeds, the Markhoz (Iranian Angora) is one of the most notable in the northwest of Iran (mainly the Kurdistan region) with valuable mohair. The purpose of this study was to search for a way to genetically improve reproduction as well as fertility to increase their population. Based on the results of this research, a high-fecundity doe can be screened; hence flock parturition will improve.

The research was carried out on cows fed with a conventional or green fodder diet in order to determine the physicochemical characteristics and mineral content in milk. The data show similar results except for the fat content, which is higher in milk coming from cows fed with hydroponic barley. Minerals were in the range reported elsewhere. The hydroponic fodder system seems to be an ideal solution in places where it is not possible to grow fresh fodder or where pasture grazing is nonexistent.

The results of this research indicate that eggs from organic farming have a richer chemical composition in terms of the content of nutrients such as calcium, magnesium and zinc compared with eggs obtained from caged hens. Therefore, consumers purchasing eggs should consider the system in which the hens were reared, as eggs can be a valuable source of these elements in the diet.

The research was carried out on lamb meat to determine the physicochemical characteristics and oxidative stability of lipids. The analysis was performed on fresh and 14 d aged longissimus lumborum and gluteus medius muscles. The meat aging determined all physicochemical features except protein and fat content. The tenderness of meat was better in muscles aged for 14 d. The muscles differed in the degree of lipid peroxidation in both fresh and aged meat.

Sulfur amino acids, such as methionine, and minerals, such as zinc, are the most important nutrients affecting wool production. This study evaluated an effect of zinc and methionine supplementation on Merino ewes wool features and zinc content in wool fibers. Wool fibers' length, thickness, breaking force and zinc content were higher in the supplemented group. Histological structure of fibers from both groups did not differ. The results are beneficial from the processing point of view.

The study was carried out to investigate the effects of Camelina and hempseed cakes in the diets of ducks on the intramuscular fatty acid profile. Our study showed that supplementing Camelina cake in duck diets makes it possible to develop functional food, i.e. meat with a significantly higher content of ALA, total n-3 PUFA and the lowest ratios of n-6 / n-3 fatty acids in muscles. Duck diet with hempseed cake produces exceptional quality meat with an enriched content of n-6 GLA.

Glycerol, a by-product of biodiesel production, is non-toxic to humans and environment. With the increase in demand for fuels obtained from biomass, the amount of glycerine waste increases. There are many ways to dispose it (pharmaceutical, cosmetics and chemical industry), but its utilization is still insufficient. Due to the fact that glycerine is a safe, cheap and easy to apply substance, the possibility of using it on a large scale in the aspect of chicken eggs storage seems to be possible.

The quantity and quality of beef can be increased through crossing beef bulls with dairy cows. This experiment was conducted to compare carcass traits in young bulls and steers, produced by crossing Holstein-Friesian cows with Hereford bulls. Meat from steers had higher intramuscular fat content and was tenderer and juicier than meat from bulls. Steer IMF was characterized by a more desirable n-6 / n-3 PUFA ratio. Beef from steers is a good choice for consumers who appreciate high-quality meat.

Wet brewers grain (WBG) is successfully used in animal nutrition, especially in ruminants. The low cost of this fodder also has a positive impact on the economics of production. The aim of this study was to determine the effect of the addition of WBG to lamb feed on growth, slaughter value and meat quality. Lambs fed WBG were characterized by higher daily gains and better meat quality. The results indicate that WBG could be used in slaughter lamb production as a source of cheap fodder.

In recent years, there has been a current trend in the pork market to create products based on traditional specialities, where technology such as drying, smoking and fermentation of products is used. For this reason the aim of study was to compare the genotypes from Slovakia and Poland. Genotypes from Poland are more suitable than those from Slovakia for the breeding and production of special meat products due to acceptable fattening and carcass parameters as well as the meat quality.

It has been stressed that increasing the growth velocity and muscle mass in chickens possibly resulted in trade-offs regarding product quality. Therefore, this research aimed at comparing the breast meat quality of chickens with divergent growth rates. The results suggest that selection on high growth rates could be associated with increased pH when the body weight of fast-growing birds reaches about 40 to 60 % of their growth potential and, possibly, also with increased cooking loss.

We tried to figure out whether it was possible to produce high-quality lamb meat the whole year by taking advantage of seasonal pastures. We reared lambs in winter, spring–summer and autumn. Average daily gain, carcass weight and dressing percentage increased in winter lambs. Carcass fatness decreased in spring–summer and autumn lambs which suckled their dams and also grazed in seasonal pasture. Meat from spring–summer lambs was not appreciated by the panellists in the sensory evaluation.

We examined the differences in the colour of meat during 6 days of storage between commercial (Swedish Landrace) and traditional (Swallow-bellied Mangalitsa) pig breeds. In conclusion, the meat from the free-range Swallow-bellied Mangalitsa pigs had better colour stability for 6 days of refrigerator vacuum storage compared to the meat from the modern pig breed, and our recommendation is to age this meat if it is intended to be marketed as high-quality pork.

Milk produced by two non-dairy breeds, i. e., Żelaźnieńska and Wrzosówka sheep, maintained under the same nutritional conditions, did not differ in terms of the amount of basic components. Higher amounts of PUFAs n-3, a more favorable ratio of n-6/n-3 and a lower level of cholesterol were observed in milk of the more primitive breed (i.e. Wrzosówka). We suggest that non-dairy breeds can provide high-quality milk that can positively affect the carcass quality of lambs slaughtered at low weight.

Short summary
The aim of the research was to compare the thickness and the medullation of white and coloured wool from alpacas of different ages. The colour of the wool did not significantly affect the thickness and degree of medullation of the alpaca wool. Discontinuous medullas are found even in very fine hair. With age, the mean fibre diameter increased; the share of non-medullated fibres in the fleece decreased; and the share of medullated fibres, especially those with an discontinuous medulla, increased.
