“…The NEFA and BHB concentrations are indicators of lipomobilization, with an increase in their concentrations in states of negative energy balance ( 3 ). These analytes were evaluated in experiments with calf diets, indicating their metabolic capacity and reflecting the animal’s response to nutritional differences, which depends on the nutrients absorbed and their utilization ( 44–46 ). In this study, variations were found in calves’ NEFA, BHB, and TC concentrations, which were influenced by maternal factors, such as BW, NEFA, glucose, and TG results, showing relationships between cow and calf metabolism.…”

Maternal status during the transition period can significantly impact the health and performance of Holstein dairy calves, with lasting effects on various variables. However, the relationship between maternal late gestation metabolic status, seasonality, and their impact on offspring remains unclear. This study aimed to assess the influence of maternal variables at calving on the performance, metabolism, and immunity of 28 dairy calves during their first month of life. Blood samples were collected from 28 Holstein cows at calving. Median results for maternal variables including non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHB), glucose, total protein (TP), albumin, triglycerides (TG), total cholesterol (TC), haptoglobin (Hp), body weight (BW), and body condition score (BCS) were determined. These median values served as a basis for categorizing the offspring into two groups based on their dams’ high or low degree of each maternal variable. Additionally, calves were categorized by the season of birth (Spring vs. Winter), with 14 in each. Blood samples were collected from the calves at birth and on days 1, 7, 14, and 28 to assess IgG, biochemical parameters, and haptoglobin concentration. Reactive oxygen species (ROS) production by polymorphonuclear cells stimulated by various agents was also evaluated. Clinical assessments were conducted for diarrhea and bovine respiratory disease frequencies. Despite the overall health of the cows, differences were observed in the calves between maternal groups. Heavier cows with high maternal BCS tended to have larger offspring, while high maternal BCS was associated with increased diarrhea prevalence. Low maternal BCS resulted in a stronger innate immune response, indicated by higher ROS production. Calves from cows experiencing metabolic changes during calving displayed elevated Hp concentrations. Spring-born calves were larger but had lower serum IgG concentration and reduced innate immune response compared to winter-born calves. Additionally, spring-born calves exhibited higher Hp and increased diarrhea prevalence on day 28. These findings underscore the importance of the prenatal period in determining neonatal health and suggest further research to elucidate the long-term clinical implications of maternal effects on offspring health and growth. Investigating offspring constituents later in life can provide insight into the persistence of maternal effects over time.

“…In addition, the evaluation of these metabolites helps in the clinical diagnosis of metabolic and nutritional disorders, which can cause reduced production, fertility problems and even death of the animals. (Lopes et al, 2015). Thus, the use of this tool in pasture sheep production systems can provide us with important information about the nutrients that have been ingested and those that are scarce or excess in the animal's body, and with this, propose improvements in the supplementation of these animals.…”

To verify if strategies to reduce the height of Marandu grass pasture at beginning of the deferral period change intake and metabolic parameters in sheep during the dry season, 18 crossbred females, ½ Dorper + ½ Santa Inês were used, distributed in 9 Marandu grass paddock handles to 3 drawdown strategies at the beginning of deferral period: 1) maintenance of grass with 15cm for 5 months before deferral start (15/15cm); 2) maintenance of marandu grass with 25 cm for 5 months, but at the beginning of deferral it was reduced to 15cm (25/15cm); 3) maintenance of 35 cm grass for 5 months, but at the beginning of deferral it was reduced to 15cm (35/15cm). The experiment was conducted in a completely randomized design (CRD), with 6 repetitions and repeated measures over time. Strategies to reduce the height of Marandu grass pasture, at the beginning of the deferral period, do not change nutrient intake and energy and protein metabolism. However, changes occurring in the pasture during the dry season alter these variables, and deferral is an interesting strategy to be used for forage production in winter, however, to optimize its use, it is necessary to use supplementation with concentrated rich in fermentable carbohydrates.

“…A caseína, é a principal proteína do leite integral e possui a propriedade única de coagular-se no abomaso na presença da quimosina, a qual se ativa no ambiente ácido do recém-nascido separando o leite em coágulos de proteína e soro (Lopes et al, 2015). Essa enzima é a encarregada da formação do coágulo de caseína que será digerido lenta e parcialmente no abomaso pela enzima pepsina, a qual é secretada na sua forma inativa (pepsinogênio) e ativada em meio ácido (Drackley, 2008).…”
