The aim of this study was to analyze the mineral composition of milk, the amino acid composition of milk protein, and the productivity per 305 days of lactation in crossbred cows compared to pure-breed local Ukrainian analogues. The research was conducted at cows of the Ukrainian Black-Spotted (UBS) dairy breed and crossbred cows of the first-generation obtained as a result of crossing with Brown Swiss breed and at cows of the Ukrainian Red-Spotted (URS) dairy breed and crossbred cows of the first-generation obtained by crossing of the URS dairy breed with Montbeliarde breed. In both farms there were two groups of pure-breed and crossbred cows-analogues. The mineral composition of milk and its technological properties in crossbred cows were higher compared to the pure-breed analogues. The fat content of milk crossbred cows exceeded by 0.08-0.16%, protein exceeded by 0.15-0.22%, and the main trace elements include Ca and P – by 2.66-8.83 and 2.12-7.81 mg/100 g of milk, respectively. Milk protein of crossbred cows was marked by a more balanced composition of essential amino acids (EAAs) and their ratio suitable for processing. The amount of EAAs in 100 g of milk protein of crossbred cows was 3.11-6.25% higher compared to local analogues. Crossbred cows dominated pure-breed analogues by the mineral composition of milk. The authors recommend the use of Montbeliarde or Brown Swiss breeds in commercial herds to improve the technological properties of milk.

Abstract Mugil cephalus is widely distributed across all oceans and it is a potential candidate species for aquaculture. Nutrient profiling in terms of proximate, amino acid, fatty acid and mineral composition was analyzed in muscle tissue of M. cephalus sourced from culture and wild with four different sizes (100–150 g, 151–250 g, 251–500 g and > 500 g). Results of proximate composition revealed that both the factors (resource and size) had a significant (P < 0.05) effect on moisture, crude lipid, total ash and gross energy but not on crude protein and crude fibre. Though the amino acid composition was not influenced by resource and size, the level of essential amino acids of ideal protein was higher than the recommended level by FAO/WHO for phenylalanine (43.29–45.60%), tryptophan (36.60-39.02%) and lysine (33.61–41.51%). Fatty acids like C14:0, C16:0, C18:0, C18:1c, C18:2c and γC18:3 was significantly (P < 0.05) high in cultured species compared to wild caught fish, irrespective of the size groups and the reverse was true for αC18:3, C20:4 and C20:5. The amount of calcium, phosphorus, sodium and potassium was significantly (P < 0.05) higher by 10.68, 5.82, 9.31 and 6.93% in wild caught fish than its counterpart. The potential contribution of this fish to nutritional security in terms of its daily value (DV) was calculated for one serving of 100 g fish to adult human being. Results revealed that lysine, methionine, threonine, tryptophan and EPA + DHA were considered as outstanding nutrients in this fish, irrespective of their source and size as their DV crossed > 70%. Similarly, isoleucine, leucine, phenylalanine and valine could also able to meet 50–70% of the daily needs of adult human indicating the nutritional richness of both wild and cultured M. cephalus regardless of its size.
