Animal Food Products to Support Human Nutrition and to Boost Human Health: The Potential of Feedstuffs Resources and Their Metabolites as Health-Promoters.

Recent attention has been given to animal feeding and its impact on human nutrition. Animal feeding is essential for meeting human dietary needs, making it a subject of significant interest and investigation. This review seeks to outline the current understanding of this disciplinary area, with a focus on key research areas and their potential implications.

Selective decline of bacteria colonizing the calf hindgut during colostrum to milk transition, with persistence of taxa correlating with host passive immunity.

In neonate calves, the association between gut microbial colonization and passive immunity acquisition remains largely unknown. We evaluated the effect of transition from colostrum to milk on the hindgut microbiota, and the correlations between acquired passive immunity and this microbiome. In 14 Holstein calves, colostrum quality and host passive immunity were measured, feces were sampled when feeding colostrum and after transition to milk.

Reviewing the Benefits of Grazing/Browsing Semiarid Rangeland Feed Resources and the Transference of Bioactivity and Pro-Healthy Properties to Goat Milk and Cheese: Obesity, Insulin Resistance, Inflammation and Hepatic Steatosis Prevention.

The rangeland is an ecological resource that provides multiple benefits for environment and agriculture. Grazing/browsing on rangelands is a useful and inexpensive means to produce food derived from animal products. The aim of this study was to review the benefits of producing milk and cheese under this system in terms of bioactivity and the health benefits of their consumption in model animals.

Goats' Feeding Supplementation with Pods and Their Relationship with Milk Composition: Fatty Acids, Polyphenols, and Antioxidant Activity.

Background: Research efforts have focused on the evaluation of the bioactive quality of animal products (milk, cheese, meat, and other by-products) contrasting various feeding strategies coming from different ecological zones. The study aimed to describe the fatty acids (FA), polyphenols (P), bioactive compounds (BC), and antioxidant activity (AA) of goat's milk.

Methods: Dairy goats were fed with five systems: (1) Grazing; (2) conventional diet (CD); (3) CD + 10% of (AF) pods; (4) CD + 20% AF; and (5) CD + 30% AF.

Phenolic Compounds in Organic and Aqueous Extracts from Pods Analyzed by ULPS-ESI-Q-oa/TOF-MS. In Vitro Antioxidant Activity and Anti-Inflammatory Response in CD-1 Mice.

Background: (AF) pods have been traditionally used to treat dyspepsia, diarrhea and topically for dermal inflammation. Main objectives: (1) investigate the antioxidant activity and protection against oxidative-induced damage of six extracts from AF pods and (2) their capacity to curb the inflammation process as well as to down-regulate the pro-inflammatory mediators.

Methods: Five organic extracts (chloroformic, hexanic, ketonic, methanolic, methanolic:aqueous and one aqueous extract) were obtained and analyzed by UPLC-ESI-Q-oa/TOF-MS.

Marginalization and health service coverage among indigenous, rural, and urban populations: a public health problem in Mexico.

Introduction:   Marginalization is a significant issue in Mexico, involving a lack of access to health services with differential impacts on Indigenous, rural and urban populations. The objective of this study was to understand Mexico’s public health problem across three population areas, Indigenous, rural and urban, in relation to degree of marginalization and health service coverage.

Methods:   The sampling universe of the study consisted of 107 458 geographic locations in the country.

Antioxidant activity and protection against oxidative-induced damage of Acacia shaffneri and Acacia farnesiana pods extracts: in vitro and in vivo assays.

Background: Obesity is a worldwide public health issue, reaching epidemic condition in developing countries associated to chronic diseases. Oxidative damage is another side effect of obesity. Antioxidant activity from plant components regulates at some extent this imbalance.

Fatty acid content, health and risk indices, physicochemical composition, and somatic cell counts of milk from organic and conventional farming systems in tropical south-eastern Mexico.

Organic agriculture and livestock farming is claimed to promote animal welfare and can offer animal products with better hygienic-sanitary quality, based on principles of health, ecology, fairness, and care. However, no clear advantages of organic milk (OM) versus conventional milk (CM) from tropical conditions are available. The aims of the study were to determine fatty acid profile, health-promoting (HPI) and thrombogenic (TI) indices, physicochemical composition, and somatic cell counts (SCC) of OM and CM in tropical south-eastern Mexico.

Feeding goats on scrubby Mexican rangeland and pasteurization: influences on milk and artisan cheese quality.

The objective of this study was to evaluate the effect of foraging on local scrubby rangeland versus stable feeding with high-protein concentrate as well as the compulsory pasteurization process on goats' milk and artisan soft cheese quality in terms of chemical composition and fatty acid profile. The results indicated that there were no significant differences in the energy, fat, or ash content of milk and cheese due to feeding; however, a significant influence of feeding on cheese protein and fatty acids in both milk and cheese was detected. Feeding on scrubby rangeland tended to increase the amounts of major polyunsaturated fatty acids in milk and cheese from goats.

Antioxidant activity, bioactive polyphenols in Mexican goats' milk cheeses on summer grazing.

Two feeding systems trials were carried out to determine the antioxidant activity of soft goats' milk cheeses, and also to evaluate the presence of bioactive polyphenolic compounds. Two groups (A and B), each one with 20 (BW 50+/-5 kg) French Alpine goats were employed. All animals had between 70 to 80 milking days and were milked once a day.
