Using Pregnancy-Associated Glycoproteins (PAGs) to Improve Reproductive Management: From Dairy Cows to Other Dairy Livestock
Full text linkSIMPLE SUMMARY: Pregnancy loss is a major cause of infertility in dairy animals, particularly in cattle, which affects the productivity and profitability of farms. Detecting these unsuccessful pregnancies could offer farmers the opportunity to reduce the economic damage caused by pregnancy loss. The determination of proteins secreted by the placenta and related to the presence of a viable conceptus called pregnancy-associated glycoproteins (PAGs) represents a diagnostic tool to identify pregnant or non-pregnant animals and to predict early pregnancy failures. This review describes the state of the art related to PAGs’ function, pregnancy profile, and use in reproductive management in bovine and other dairy livestock. ABSTRACT: Pregnancy success represents a major issue for the economic income of cattle breeders. Early detection of pregnant and non-pregnant animals, as well as the prediction of early pregnancy failure, can influence farm management decisions. Several diagnostic tools for pregnancy are currently available. Among these, pregnancy-associated glycoproteins (PAGs) have been shown to be useful for identifying the presence of vital embryos and for pregnancy follow-up monitoring. This review presents an overview of the PAGs’ functions, their pregnancy trends, and their use as a tool to improve reproductive management in bovine and other dairy livestock, such as small ruminants and buffalos

No full textEffects of food restriction during rabbit pregnancy on fetal biometric parameters
No full textThe rabbit is an ideal animal model for the study of fetus programming
related to maternal nutrition. Here we describe the influence of
moderate food restriction in different gestational phases on fetus
growth evaluated by ultrasound (US). Primiparous non lactating New
White Zealand does (n = 20) were assigned to four groups. Control
group was fed a standard ration while the others received a restricted
amount of food (30% restriction) during early (0–9 days), mid (9–
18 days), and late (19–28 days) pregnancy. By US scans, performed at
days 0, 4, 10, 14, 18, 22, and 26 of pregnancy, vesicle size, placental
thickness, embryo length, and biparietal diameter were measured.
Data were analyzed by ANOVA followed by Bonferroni test. Food
restriction affected vesicle size (p < 0.01) and embryo length
(p < 0.001) depending on stage of nutritional privation during
pregnancy and day of observation. However, biometric differences
might also be attributable to litter size (larger body length when the
number of live born ranging from 6 to 10; p < 0.01). In conclusion, the
results indicate that fetus size is sensitive to maternal nutrition but inutero
development is influenced by many factors that establish
intricate reciprocal relationships
