“…The application of a combined feeding system (pasture and complex feed) determined significant increases in fat and casein content in the analyzed milk samples, and these results were in agreement with those obtained in other studies [ 17 , 18 , 19 ].…”

“…The results obtained in our study on the level of lactose in milk from sheep that received mixed feed are in agreement with those from other studies that analyzed the effects of different exploitation systems. The results suggest that, if the animals that received a mixed diet (grazing supplemented with the administration of a complex fodder), the composition of sheep milk was improved [ 17 , 18 , 19 ].…”

“…As a result, it is believed that an adequate and balanced consumption of fats is necessary; therefore, fatty acids should be part of the diet, but in an adequate ratio to provide the body with the necessary content. The results of the studies that followed the increase in the quantity and quality of sheep’s milk through the administration of additional fodder complexes were encouraging [ 17 , 18 , 19 ].…”

Milk and dairy products are among the foods preferred by consumers, as they are rich in nutrients, have high biological values, are easily accessible, and present a low risk to health. This study aimed to comparatively analyze the milk from sheep of the Turcana breed that were subjected to different feeding systems. The milk from the sheep was analyzed quantitatively and qualitatively; in this sense, the following were determined: daily milk production (DMY), physical parameters (pH, freezing point), chemical composition (lactose (L), fats (F), total proteins (TP), non-fat solids (Snf)), the content of heavy metals and trace elements (Zn, Cd, Cu, Fe, Mn, Pb), and microbiological parameters (the number of somatic cells (SCC), the total number of aerobic mesophilic germs that develop at 30 °C (NTG), the number of coliform bacteria (CT), the number of Staphylococcus aureus). Administration of the fodder complex produced, on the farm determined a slight quantitative increase in milk production, as well as in fat, protein and lactose content. The content of trace elements Zn, Fe, and Mn registered increases in milk samples from sheep that were administered the fodder complex. The content of heavy metals did not indicate any source of pollution in the grazing area. Furthermore, the microbiological parameters were within the allowed limits, indicating a good general state of health at the emergency level and the absence of microbiological contamination of the milk samples.

“…The protein percentage is significantly higher in the APG group, showing that grazing affects the protein percentage as compared to confined animals. Kuleile et al (2021) studied the performance of lactating ewes in four groups: control group, T1 forage only, T2 forage with concentrate, and T3 forage with urea molasses and concentrate. The T1 group showed better milk than the other groups, and the T3 group showed better amounts of milk protein, density, and solids not fact (SNF) than the control group and T2.…”

Abstract. This study aimed to evaluate the effect of concentrate-based feeding (CF) and artificial pasture-based grazing (APG) management systems on milk yield, fatty acids, nutritional indices, and milk physicochemical characteristics of Awassi ewes. The research involved 300 heads of Awassi ewes, which were divided into two groups. Awassi sheep were managed in a CF and APG system to test the milk yield characteristics. The results showed a significant (P<0.01) difference in milk yield and lactation length between CF and APG management systems of ewes. The average daily milk yield showed a nonsignificant difference for both management systems, and no significant changes (P>0.05) in the chemical composition of CF and APG management systems were observed. Palmitic (C16:0), myristic (C14:0), stearic (C18:0) capric (C10:0), and lauric (C12:0) acids were the major saturated fatty acids found in milk from both management systems. The level of linoleic acid (C18:2 n-6) was significantly different in both treatments (P<0.05), but the linolenic (C18:3 n-3) acid level was nonsignificant in milk from the CF and APG management systems. The hypocholesterolemic / hypercholesterolemic (h / H) fatty acid and thrombogenicity (TI) ratios were significantly different (P<0.05); however, the atherogenicity (AI) had no significant difference between confined and grazing systems. In conclusion, it can be said that the lactation length and lactation milk yield were prolonged by the APG management system, though the milk composition and quality were not significantly affected.

In Caraș-Severin County, Romania, the integration of sustainable agricultural practices with organic dairy production represents a unique opportunity to promote agro-tourism farms and guesthouses. This study examines the synergy between the chemical composition of pastures from three farms in different alleys and the impact on the chemical composition of dairy products produced on those farms. Thus, the comparative analysis of two types of traditional cow’s cheeses (soft and mature) from three different areas of Caraș-Severin County was pursued, as well as of the feed given to the animals from which the raw material for obtaining the cheeses originated. Initially, the physicochemical profile of the pastures (fresh grass and grass hay) was analyzed in terms of proximate composition (moisture, lipids, proteins, ash and carbohydrates), and the content of bioactive compounds (total polyphenols, antioxidant activity using the DPPH method). The proximate composition of the cheese samples, including moisture, lipids, proteins, ash and carbohydrates was analysed, and the content of fatty acids. A correlation was also made between the content of bioactive compounds in feed samples and fatty acid profile of the cheese samples. Our findings demonstrate that the geographical area and the chemical composition of the pasture have a considerable influence on the physicochemical characterization and fatty acid composition of the cheese. The cheese from the mountain area had a higher fat, protein and polyunsaturated fatty acid content compared to the samples from the hill and plain areas.
