The objective of this study was to determine the chemical composition, fatty acid profile, and values of healthy indices of milk from a specialized farm of Polish Coldblood mares of different ages, birth orders, and lactation stages. Milk samples (n = 48) were collected for analysis in weeks 10, 15, and 25 of lactation from mares aged between five and 14 years. The study showed that the stage of lactation has a significant effect on the fatty acid (FA) profile of the milk produced on the farm. The highest concentration of monounsaturated and polyunsaturated FAs was found in milk produced from the 15th week of lactation. The milk was also characterized by low values of atherogenic and thrombogenic indices, which indicate the health benefits of milk with respect to the content of fatty acids and their potential to prevent or cause atherosclerosis and thrombosis. The study also found a significant correlation between the number of foalings (birth order), the fatty acid profile, and atherogenic index of milk produced on the farm. The findings from the study indicate that it is possible to modify the fatty acid profile of bulk tank milk through appropriate management of the age structure of the herd of mares. To confirm this dependence, the study will be continued on a larger group of mares.

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.

The objective of this research was to assess the effects of including oil-rich feedstuffs in diets for lactating goats on the fatty acid (FA) profile of their milk. Thirty-six Murciano-Granadina goats were randomly assigned to three treatment groups, namely a control diet (CTRL), a diet based on whole rapeseed (RS), and a diet based on pumpkin seed cake (PSC). The diets were composed of 1 kg hay (70 % Italian ryegrass, 30% alfalfa) and 1.24 kg concentrate, and were formulated to be isoenergetic and isonitrogenous. Milk yield and its contents of protein, fat and lactose did not differ significantly among the groups. However, including oil-rich feeds in the diet altered the fatty acid profile of the milk significantly, decreasing its saturated fatty acid (SFA) content and increasing its content of unsaturated fatty acids (UFAs). Effects on polyunsaturated fatty acids (PUFAs), conjugated linoleic acid (CLA), and the n-6 to n-3 ratio depended on the source of dietary lipids. The PSC augmented diet increased the relative amount of PUFAs and fatty acid methyl esters (FAME) in milk (+25 %) significantly In comparison with CTRL, whereas the RS diet produced a limited and statistically insignificant increase (+7.5%). The concentration of CLA was higher in milk from does fed the PSC diet, whereas the n-6 to n-3 ratio was lower in milk from does fed RS. These preliminary results form the basis for developing premium dairy products that are enriched in fatty acids that are more favourable for human health.

Background: Little information is available on carcass quality in nulliparous and primiparous ewes of different breeds and genetic groups. Objective: To evaluate the effect of genetic group, pregnancy, age and their interactions on carcass traits, meat quality and fatty acid profile in sheep. Methods: Eighty-five Santa Ines ewes and their crosses with Texel, Dorper and Ile de France, aged 12 month were bred with White Dorper rams to assess the influence of pregnancy on carcass composition and meat quality. After weaning, all ewes (nulliparous and primiparous) were fattened for slaughter at 21 months of age. A further 24 six to twenty one-month-old female lambs from the same genetic groups were included in the analysis to determine the fatty acid profile. Results: Genetic group affected muscle and fat weight as well as the eye muscle length. Fat weight, muscle and fat ratios, subcutaneous fat thickness and cooking loss were affected by pregnancy with nulliparous females being fatter. Meat purpose breeds such as Dorper, Texel and Ile de France showed better meat quality compared to the Santa Ines hair breed. Of the 19 identified fatty acids, saturated were present in greater quantities, especially stearic and palmitic. Omega-6 content was influenced by age and pregnancy. Conclusions: Younger and nulliparous females have better carcass quality in terms of fatty acid composition.Keywords: commercial cuts, fat content, meat breeds, ovines, Santa Ines, slaughter age.  Resumen Antecedentes: Existe poca información sobre la calidad de la canal en ovejasjóvenes nulíparas y primíparas de diferentes razas y grupos genéticos. Objetivo: Evaluar la influencia del grupo genético, de la preñez, de la edad y sus interacciones sobre la composición de la canal, calidad de la carne y perfil de ácidos grasos en la carne de ovejas. Métodos: Ochenta y cinco ovejas de 12 meses de edad de raza Santa Inés y sus cruces con Texel, Dorper y Ile de France fueron cruzadas con carneros White Dorper para evaluar la influencia de la gestación sobre la composición de la canal y la calidad de la carne. Después del destete, todas las ovejas (nulíparas y primíparas) fueron engordadas y sacrificadas a los 21 meses de edad. Otras 24 ovejas de seis a veintiún meses de edad del mismo grupo genético fueron incluidas en el análisis para determinar el perfil de ácidos grasos. Resultados: El grupo genético afectó el peso del músculo y de la grasa, como también la longitud del ojo del músculo. El peso de la grasa, porcentajes de músculo y grasa, el grosor de la grasa subcutánea y las perdidas por cocción fueron afectadas por la preñez, siendo más gordas las hembras nulíparas. Los grupos genéticos especializados en producir carne como Dorper, Texel e Ile de France mostraron mejor calidad de carne comparado con la raza Santa Inés. De los 19 ácidos grasos identificados, los saturados estaban presentes en mayores cantidades, especialmente esteárico y palmítico. Los contenidos de Omega-6 fueron influenciados por la edad y la preñez. Conclusiones: Las ovejas más jóvenes y nulíparas tienen mejor calidad de carcasa en términos de composición de ácidos grasos.Palabras clave: contenido de grasa, cortes comerciales, edad de sacrificio, ovinos, razas de carne, Santa Inés.  Resumo Antecedentes: Existe pouca informação sobre a qualidade da carcaça em ovelhas jovens nulíparas e primíparas de diferentes raças e grupos genéticos.

This study aimed to evaluate the effects of supplementation with sunflower seeds and vitamin E for fattening lambs, on the chemical composition, cholesterol, vitamin E level, fatty acid profile and lipid oxidation of meat from sheep. Four treatments were evaluated, as follows: SC – basal diet consisting of sugarcane + concentrate; SCS – basal diet supplemented with sunflower seed; SCE – basal diet supplemented with 1000 mg vitamin E; SCSE – basal diet supplemented with sunflower seed and 1000 mg vitamin E. The Longissimus lumborum muscle of 32 Ile de France lambs, which were slaughtered when their bodyweight reached 32 kg, was used. The chemical composition of the lamb meat was not significantly different (P > 0.05) between the treatments. Sunflower seed supplementation increased (P < 0.05) the levels of linoleic acid, vaccenic acid and conjugated linoleic acid. Inclusion of vitamin E in the diet increased (P < 0.05) the concentration of vitamin E in the meat while decreasing lipid oxidation. Considering the current demand for healthy foods, inclusion of sunflower seeds and vitamin E in the diet of sheep is a viable possibility.
