“…When the animal stands up for the fi rst time and spends 10 min standing, its energy expenditure is also increased by 100%. When it is a bit stronger and is able to stand for more than 30 min, heat production is increased by 40% on average over this period (personal results) [131].…”

The transition from intra-to extra-uterine life is one of the greatest physiological challenges that occur in the life of animals. Immediately after birth, newborn calves have to adapt to new environmental and feeding conditions. Namely, at birth a break of the thermal balance occurs, since calves abruptly pass from a 38.8°C temperature in utero to an environmental temperature that is generally lower than 20°C. Additionally, at birth, the energy intake shifts from a continuous parenteral supply of nutrients (mainly glucose) to discontinuous colostrum and milk intake with lactose and fat as the main energy sources. Therefore, the most important issues related to metabolic changes during the transition from intra-to extra-uterine life are related to maintaining the homoeothermic conditions and control of energy metabolism. Those metabolic adaptations are under control of the endocrine system that is relatively mature at birth, but still requires morphological and functional changes after birth. Key hormones whose concentrations are signifi cantly changed around birth and are involved in an adequate adaptation of calves to extra-uterine life are those related to stress at birth (cortisol and cathecholamines), glucoregulatory processes (insulin and glucagon), thermogenesis (thyroid hormones) and growth (IGF axis).

“…Eigenmann et al (1983) and Donovan et al (1986) found that this disorder had a detrimental effect on the level of passive immunity, decreasing the sucking activity. Kasari (1989) and Vermorel at al. (1989) determined that dystocia lowered the concentrations of glucose and NEFA.…”

“…Namely, this group revealed the highest levels of glucose and cholesterol. A high level of glucose in the one-day-old calves is evidence of proper acid-base balance and respiratory functions, which in turn account for the fast adaptation of the newborn to the external environment (Kasari, 1989;Vermorel et al, 1989). According to Kurz and Willet (1991), the levels of glucose and cholesterol in calves of that age are associated with the time elapsed between birth and the first ingestion of colostrum.…”

The study was carried out on 166 single-born sucking calves of the Lowland Black-and-White breed and crosses of this breed with Holstein-Friesian. Samples were taken from calves at the age of 1 day (24 ±6 hours) and 5 days (±1 day). The blood components assayed were: glucose, bilirubin, cholesterol, GOT, GPT, total protein, albumins, and alpha-, beta-and gammaglobulins.Statistical analysis of data showed that parity and periparturient disorders in cows had a significant influence on blood composition and mortality rate in calves. Calves born from second parity cows had the most advantageous blood composition, revealing the highest level of glucose and cholesterol, whereas in calves born from older cows these constituents showed the lowest values.Calves derived from cows with periparturient disorders had decreased glucose, total protein, betaand gammaglobulins levels. Dystocia and milk fever had the most unfavourable effects on the biochemical and immunological status of calves.

“…Vigor, interchangeably used with the word vitality, can be defined as having the capacity to live and grow with physical and mental energy and strength [6]. Reduced newborn calf vigor from dystocia can result from injury, inflammation, inability to maintain homeostasis, as well as from hypoxia and acidosis [1,[7][8][9]. These physiological effects can have behavioral repercussions, such as having reduced motivation to perform natural behaviors for survival, including standing up and suckling colostrum after birth [10].…”
