Effect of Different Levels Density Flaked Corn on Growth Performance, Blood and Rumen Parameters Holstein Suckling Calves

Transmissible spongiform encephalopathies (TSE) are caused by dietary oral exposure to infectious prion proteins (PrPSc); however, the mechanism behind the uptake of PrPSc in the intestines is poorly understood. In addition, epidemiological studies of BSE showed that most cattle are exposed to the agents in the first 6 months of life, during the suckling and weaning periods. In the present stud...

Limited literature is available about women who wish to breastfeed but experience unexpected feelings of aversion in reaction their infant suckling at the breast while breastfeeding.

Lactation in the rat is characterized by the suppression of pulsatile LH secretion, a large increase in food intake, and changes in energy balance due to the metabolic drain of milk production. The change in energy balance may be a major component in altering reproductive function. A number of factors may contribute to changing energy balance of a lactating animal; one is leptin, the product of...

Introduction: Cough and expiration reflex are major lower airway defense mechanisms that have not been studied throughout development in relation with the feeding behavior. Aim: To describe airway defense reflexes evoked by mechanical stimulation of the trachea in developing rabbit pups. Material and Methods: Sixty one pups were allocated to 3 groups according to their feeding behavior: sucklin...

Performance and mortality of hares were evaluated for 2 consecutive years in a large farm in Veneto Region (Northern Italy). On average, fertile reproductive pairs (n=318) gave birth 4.8 times and produced 11.4 live leverets, weaned 8.4 leverets and produced 7.0 growing hares (60 days) every year. Mean mortality was 3.6%, 22.9%, 9.7% and 2.5% in newborn (0 to 2 days of age), suckling (3 to 25 d...

BACKGROUND Intrapartum drugs, including fentanyl administered via epidural and synthetic oxytocin, have been previously studied in relation to neonatal outcomes, especially breastfeeding, with conflicting results. We examined the normal neonatal behavior of suckling within the first hour after a vaginal birth while in skin-to-skin contact with mother in relation to these commonly used drugs. Su...

Patterns of infant feeding, basal prolactin concentrations, and ovarian activity were studied longitudinally in 27 breast-feeding mothers from delivery until first ovulation. Suckling frequency (6.1 feeds/day) and suckling duration (122 mins/day) reached peak values four weeks post partum and remained relatively constant until the introduction of supplementary food at a mean of 16 weeks post pa...

We examined in rat pups the relation between the decline of suckling and the emergence of independent ingestion, and the role of milk delivery conditional on nipple attachment in the maintenance of suckling. Fifteen-day-old litters were reared for either 5 or 10 days, and 20-day-old litters for 5 days by either a thelectomized (no nipples), ligated (nipples but no milk), or intact (nipples and ...
