A comprehensive study on packaging used in commercially available milk products from Spanish markets has been presented. Concentrations of four phthalates, seven parabens and BPA were determined in forty-two milk products. Eleven brands and five types of packaging (metallic aluminium bag, carton, high-density polyethylene, metal pail and polyethylene terephthalate) were included in the study. BPA showed the lowest concentrations (8.3 pg/g f.w.), far below those of phthalates (6431 pg/g f.w.) and parabens (6234 pg/g f.w.). Metallic aluminium bags were the least migrating packaging (considering plasticisers and monomers) followed by HDPE bottles, in the case of phthalates. Parabens showed their highest concentrations for fresh-milk samples. Levels found were far below the specific migration limits established by the EU and the cumulative hazard index was lower than 1, indicating that adverse health effects were not expected. In general, the results found in Spanish samples were lower than those reported in other countries.

Intramammary dry-off treatment is widely considered an effective method for preventing and curing intramammary infection (IMI) in lactating cows; however, it is not commonly used in small ruminants like goats. Therefore, this study was designed to evaluate the effect of an approved cefazolin-based intramammary treatment on the milk microbiota of Alpine dairy goats during the dry and early lactation periods. Sixty goats were randomly selected based on bacteriological results and randomly allocated into the control group (CG) or the treatment group (TG).

The effect of fermented foods on healthy human gut microbiota structure and function, particularly its seasonal preference and frequent long-term consumption, has been largely uncharacterised. Here, we assess the gut microbiota and metabolite composition of 78 healthy Indian agrarian individuals who differ in the intake of fermented milk and soybean products by seasonal sampling during hot-humid summer, autumn and dry winter. Here we show that, seasonal shifts between the Prevotella- and Bifidobacterium/Ruminococcus-driven community types, or ecological states, and associated fatty acid derivatives, with a bimodal change in Bacteroidota community structure during summer, particularly in fermented milk consumers.

Immunoglobulin A (IgA), the most abundantly produced antibody at mucosal surfaces, is thought to play key roles in immune responses to respiratory and enteric pathogens and in the regulation of commensal colonization. Low IgA levels have been associated with recurrent infections and immune dysregulation, including inflammatory bowel disease and autoimmunity. Levels of IgA in maternal breast milk and infant stool are both inversely associated with the emergence of immune responses to food antigens in infants and, in naturally resolving food sensitivity and immunotherapy protocols, the induction of IgA antibodies to dietary antigens has been associated with the acquisition of food tolerance.

Provision of supplemental concentrate in an automated milking system (AMS) is commonly used to encourage voluntary attendance, however, the motivation to voluntarily milk is highly variable between cows. The objectives of this study were to determine if dairy cow personality is associated with: 1) their short-term response to changes in factors believed to motivate voluntary AMS visits such as udder pressure and provision of supplemental feed (modulated by longer milking intervals or removal of AMS concentrate, respectively); and 2) their milking activity, production, and feeding behavior after returning to pre-treatment AMS milking interval and concentrate feed settings (i.e.

Experimental objectives were to create a chronic inflammatory model to evaluate the effects of persistent immune activation on metabolism, inflammation, and productivity in lactating dairy cows. Twelve lactating Holstein cows (631 ± 16 kg BW; 124 ± 15 DIM) were enrolled in a study with 2 experimental periods (P); during P1 (5 d), cows were fed ad libitum and baseline data were obtained. At the initiation of P2 (7 d), cows were assigned to 1 of 2 treatments: 1) saline-infused and pair-fed (PF; 5 mL intravenously (IV) sterile saline on d 1, 3, and 5; n = 6) or 2) lipopolysaccharide infused and ad libitum-fed (LPS; 0.
