“…In particular, the multifocal-confluent necrosis, as revealed by histology, was significantly associated with a poor outcome for the puppies within seven days from birth. Because multifocal necrosis was the main finding associated with poor outcomes, it would be interesting to detect any alteration of placenta perfusion with advanced diagnostic imaging, reported as safe for use in pregnant mare and bitch [ 36 , 37 ], to have data to predict puppies outcome or plan intensive care at birth.…”

Placenta is essential for the development of the fetus, and its impaired function can lead to a negative outcome (i.e., neonatal mortality). In dogs, investigations on placenta histology and neonatal outcome in healthy bitches are lacking, and a contribution is provided in this study to emphasize the use of placenta histology in practice. Fifty-one placentas from 11 litters were collected during cesarean section, classified according to the litter size (large (L) or small (S)) and the outcome, this latter as healthy (Group 1) or dead within 7 days (Group 2). The placenta/puppy weight ratio (PPR) was calculated, and specimens were formalin-fixed and paraffin-wax embedded, and on the resulting histological slides, capillary density (CD) was quantified. Among necrosis, calcification, and intravascular leucocytes, only the presence of multifocal-confluent necrosis (significantly more frequent in Group 2) was associated with a higher risk of death within 7 days (odds ratio = 30.7). Mixed logistic regression ruled out the effect on death both of a bitch and cesarean type (programmed vs. emergency). PPR and CD values were associated with litter size; large litters had lower PPR (p < 0.01) and higher CD (p < 0.05) than small litters. The relationship between PPR and CD was negative and significant (p < 0.01). Necrosis was a frequent finding in canine placentas, but only when multifocal-confluent was it associated with a poor outcome. The litter size influenced PPR (lower in L) and CD (higher in L), and this is likely due to the plasticity of placenta adaptation.

“…Perfusion patterns of the mammary gland and inguinal lymph node in intact bitches during the different stages of the estrous cycle have been described (Vanderperren et al, 2018). Maternal and foetal vessels of pregnant bitches were studied with UCA in the first twothirds of gestation, without any clinically relevant adverse effects (Orlandi et al, 2019).…”

Ultrasonography is the imaging technology of choice for the evaluation of the reproduction system and pregnancy in both humans and animals. Today, ultrasound equipments are smaller, cheaper, and much more efficient. These upgrades, along with image digitization, have pushed ultrasound into the point-of-care setting. The most recent advances of different ultrasound techniques and their potential use in reproduction imaging of small animals are described in this review. 2 | DOPPLER The Doppler effect describes a change in the wavelength of energy transmitted as sound waves as a result of motion of their source or their receiver. The most commonly used indices to describe the waveform of the spectral Doppler are resistance index (RI): RI = (S−D)/S, systolic/diastolic (S/D) ratio: S/D and pulsatility index (PI): (S−D)/A

“…Nonstandard conceptions or else imminent abortions in dogs can diagnose by Contrast-enhanced ultrasound (CEUS). As it permits assessment of the maternal and fetal vessels in the first two-thirds of gestation deprived of any clinically pertinent inauspicious impact (Orlandi et al, 2019). Despite all these new-age technologies, the old genetic makeup is essential to the preservation of animal category and fighting against new health disasters of an animal.…”

“…Since several centuries, the ultrasonography used for evaluation of reproductive tract and diagnosis of pregnancy in animal. Contrast-enhanced ultrasonography (CEUS) is an emerging technique for a pregnancy test and use it for assessment of fetal-maternal circulation during pregnancy in dogs of different gestation ages (Orlandi et al, 2019). Different types of immunoassays are very useful to evaluate the reproductive performance of animals monitors the progesterone level to evaluate the reproductive status of the animal (Posthuma-Trumpie et al, 2009).…”

In this epoch, the tremendous increase in the world population accounts for the continuous supply of foodstuff. According to the FAO report, the global population is probable to cross the 9 billion in 2050. With constant population pressure, we are going to face the challenges of food shortage globally about agriculture. The animal production field provides a major share in the supply of foodstuff to compensate for the stress of food scarcity. By adopting the advanced technologies in the animal production field, its productivity can enhance significantly. Innovation in technology has made work easier with the development of different software and the internet. Technologic development made farmers work more contentedly hence, ultimately amplifying the animal production, proficiency, profitability as well as providing a prompt way for livestock sustainability. The animal production consists mainly of 8 factors including 3 major (animal breeding and genetics, animal nutrition, and reproductive performances) and 5 minor (health observation, farm management, water, manure, machinery, environment control, milking automation and electronic identification). The use of advanced technologies in these sectors is found to be fluent by intensifying the ratio of sustainable livestock farming and the welfare of mankind in terms of food security. In this review, innovative tactics and techniques for animal production are potted with positive research results and their drawbacks as well. The use of innovative technologies in their respective fields is close to taking control of whole world manufacturing under its hand to accomplish the world prerequisite regarding food scarcity.
