Special Issue Information

Dear Colleagues, 

Reproductive events are closely related to the normal metabolic and endocrine status of dogs and cats. Endocrine homeostasis is of the utmost importance for the adequate functioning of the reproductive system and, thus, guaranteeing reproductive efficiency. Conversely, reproductive hormonal and metabolic imbalances trigger serious disorders and are responsible for significant decreases in health and well being. Despite the enormous amount of scientific knowledge accumulated over the last years, there are still unknown issues, such as the impact of metabolic and endocrine imbalance on several reproductive events (spermatogenesis, male reproductive disorders, pregnancy, whelping, lactation and neonatal health). Therefore, understanding new concepts around the canine and feline reproductive metabolism and hormonal profile is needed, making it possible to build accurate therapeutic and management approaches. This Special Issue plans to give an overview of the most recent advances in the field of endocrinology and metabolism in companion animal reproduction. The aim of this Special Issue is to provide selected contributions on the physiology, pathology and treatment applications of reproductive hormones and metabolism.

Potential topics include, but are not limited to:

  • New endocrine approaches in canine and feline reproduction;
  • Metabolism disruption related to infertility;
  • Endocrine changes of prostatic hyperplasia in dogs;
  • Neonatal metabolism;
  • Effects of stress and pain during the perinatal period;
  • Endocrine changes during normal and dystocial whelping;
  • Hormonal equilibrium and disequilibrium during reproductive senescence;
  • Impact of metabolic imbalance during gestation.

Neonatal mortality in dogs reaches up to 40%. Due to the high rates, promptly detecting the causes and preventing newborns from dying are extremely important. Vitality evaluation, blood parameters, and the degree of meconium staining on the skin are valuable resources in canine perinatology. In this study, 435 puppies from 85 bitches close to parturition were recruited and divided into four quartiles according to the puppy’s birth weight: Q1 (127–200 g) n = 110 puppies, Q2 (201–269 g) n = 108 puppies, Q3 (270–388 g) n = 108 puppies, and Q4 (389–464 g) n = 109 puppies. This experimental article aimed to report the effect of birth weight on the blood profile variables, the vitality of newborn puppies, and the meconium staining degree, integrating these three aspects. It was concluded that the weight of newborns was correlated with the degree of meconium staining, presenting more cases of severe meconium staining in the puppies of the highest birth weight group. The weight of the newborns was correlated with a higher number of stillbirths and alterations in the blood variables, showing the most severe cases of metabolic acidosis, hypoxia, and hypoglycemia in the puppies of the Q4 quartile. On the contrary, no statistically significant correlations were found between the weight of newborns and vitality. Nevertheless, the analysis of the results showed that the most vigorous puppies were found at Q1; however, at minute 60 after birth (AB), all the puppies in the four quartiles standardized their vitality scores.

Overweight affects nearly 40% of dogs. The objective of this study was to explore the hypothesis of the Developmental Origins of Health and Disease through the association between birth weight and adiposity in adult dogs. The association between body condition score (BCS) and subcutaneous fat thickness (SFT), measured in the flanks, abdomen and lumbar regions, was assessed in a population 88 adult Labradors (>1 year). Significant positive moderate correlations between BCS and SFT were described. A linear mixed-effects model was used to investigate the association between birth weight and SFT by adjusting for sex, age, neuter status and the anatomical site of the measurement. The results showed that SFT values increased with age and were higher in sterilized than in entire dogs. In addition, SFT values were higher in the lumbar region compared to the other anatomical sites. Finally, the model revealed a significant association between SFT and birth weight, suggesting that, as in other species, dogs with the lowest birth weights have thicker subcutaneous fat at adulthood than the others. The assessment of visceral adipose tissue and the relative importance of birth weight among the numerous risk factors of overweight remains to be explored in dogs. Full article

The thermal stability of newborns is an essential parameter that can be recorded to evaluate neonatal care. Knowing the thermal windows to evaluate and maintain a constant temperature helps significantly reduce neonatal mortality. This study aimed to assess the superficial temperature alterations in the distinct thermal windows of puppies with mothers of diverse weights and their repercussions. We evaluated the superficial temperature using infrared thermography at eight thermal windows and seven different times: when wet due to the fetal fluid immediately after birth until 24 h of life in newborn puppies from bitches divided into four bodyweight groups. The results revealed a positive correlation between the dam’s weight and the ability to achieve thermostability in the newborn puppies in all the evaluated thermal windows. The time effect showed the lowest temperatures when the puppies were still wet, a gradual increase, and the highest temperature at 24 h after birth. The thermal windows with the highest temperatures were abdominal, thoracic, nasal, and upper left palpebral, and those with the lowest were the thoracic limb brachial biceps, thoracic limb elbow, metacarpal, and femoral pelvic limb. A significant increase in the temperatures in the thermal windows of the abdominal, thoracic, and upper left palpebral immediately after ingesting colostrum was observed. The weight of the dams is an important factor that positively intervenes in the thermoregulatory capacity of the puppies, especially when newborns are dry and have been passed 24 h after birth.
