Effect of mastitis during early-stage pregnancy on the immunity levels and pregnancy function of goats
In this study, we investigated the effects of mammary inflammation induced by lipopolysaccharide (LPS) and Staphylococcus aureus (SA) infusions on pregnancy function during early pregnancy in goats. In Experiment 1, pregnant goats were subjected to an intramammary LPS infusion for 1 week from Days 60-66 after natural mating (n = 5), and in Experiment 2, they received intramammary infusions of either saline, LPS, or SA for 1 week from Days 45-51 after natural mating (n = 15). Blood was collected to determine the plasma cytokine, cortisol, 13,14-dihydro-15-keto-prostaglandin F2α (PGFM), and progesterone levels. Pregnancy le...

The importance of developmental programming in the dairy industry
Anim Reprod Sci. 2024 Feb 5;262:107428. doi: 10.1016/j.anireprosci.2024.107428. Online ahead of print.ABSTRACTThe concept of developmental programming suggests that environmental influences during pre- and early postnatal life that can have long-term effects on future health and performance. In dairy cattle, maternal body growth, age, parity and milk yield, as well as environmental factors during gestation, have the potential to create a suboptimal environment for the developing fetus. As a result, the calf's phenotype may undergo adaptations. Moreover, developmental programming can have long-term effects on subsequent bir...

Refrigerated storage and cryopreservation of hormonally induced sperm in the threatened frog, Litoria aurea
Anim Reprod Sci. 2024 Jan 29;262:107416. doi: 10.1016/j.anireprosci.2024.107416. Online ahead of print.ABSTRACTAs sperm cryopreservation and other assisted reproductive technologies (ARTs) advance in common amphibian species, focus on applying non-lethal sperm collection methods to the conservation and genetic management of threatened species is imperative. The goal of this study was to examine the application of logistically practical ART protocols in a threatened frog (Litoria aurea). First, we tested the efficacy of various concentrations of human chorionic gonadotropin (hCG) (20, 40 IU/g bodyweight) and Gonadotropin re...

Effect of anti-adhesive supplement doses on sperm motility characteristics in the European whitefish (Coregonus lavaretus)
Anim Reprod Sci. 2024 Jan 28;262:107423. doi: 10.1016/j.anireprosci.2024.107423. Online ahead of print.ABSTRACTSperm adhering to glass slides is one of the main problems during fish sperm motility analyses with CASA systems. To mitigate this, albumin is the supplement added most frequently to activating solutions. However, there is no data on the use of supplements other than albumin (in various concentrations) in analyses of European whitefish (Coregonus lavaretus) sperm motility. This issue was investigated in the presented research using three anti-adhesive supplements (albumin, casein, Pluronic F-127) that were added t...

In vivo exposure to high temperature compromises quality of the sperm in Colossoma macropomum
Anim Reprod Sci. 2024 Jan 18;262:107412. doi: 10.1016/j.anireprosci.2024.107412. Online ahead of print.ABSTRACTIncreases in temperature can affect the reproduction of fish by decreasing the quality of gametes for fertilization. Therefore, this study aimed to evaluate the in vivo effect of temperature on the production and sperm quality of Colossoma macropomum, which is an economically relevant species for Brazil, and other countries. Broodstock were exposed for 10 days at temperatures of 29 °C (n = 4) and 35 °C (n = 4). After exposure, semen was collected and sperm quality was evaluated for kinetic, biochemical, morpholo...

Altered expression of angiogenic factors in dominant preovulatory follicles of dairy cattle treated with ACTH
Anim Reprod Sci. 2024 Jan 24;262:107415. doi: 10.1016/j.anireprosci.2024.107415. Online ahead of print.ABSTRACTStudies in cows have reported that ovulation, steroidogenesis and angiogenesis are affected by stress and consequently fertility decreases. The purpose of this study was to evaluate the effects of ACTH administration during the preovulatory period on the expression of growth factors (CD-31, PDGF-A, PDGF-B, VEGFA-164, VEGFA-164b, VEGF-R1 and VEGF-R2) associated with the angiogenic process by immunohistochemistry in cows (n = 14). Results evidenced the expression of these growth factors in theca and granulosa cells ...

Effects of vibrations during boar semen transport: Low-temperature transport as a new management tool
This study evaluates the effects of TV after novel 5 °C transport compared to a 17 °C control. Ejaculates of 18 fertile Piétrain boars, diluted in a split sample procedure using Androstar Premium® (AP, 5 °C storage) or Beltsville Thawing Solution (BTS, 17 °C storage), were subjected to transport simulation using a laboratory shaker IKA MTS 4. The timing was set according to the respective processing protocols: for 17 °C BTS samples, TV simulation was performed the day of collection, 5 °C AP samples were subjected to TV the day after collection following completion of the established cooling curve to 5 °C. Six samp...

Artificial reproduction of wild and pond-cultured common tench (Tinca tinca) under controlled conditions
In this study, two experiments were conducted in which the influence of hormonal agents (Ovopel and Ovaprim - experiment I) and the origin of the spawning stock (wild and pond-cultured - experiment II) on the success of reproduction in terms of ovulation rate (%), latency time (h), pseudo-gonadosomatic index (PGSI, %), hatching rate (%), abnormal larvae rate (%), and spawning efficiency coefficient (Se) were examined. While the wild fish could not reproduce in the absence of hormonal treatment with 0 % ovulation rate. In all tested hormonal treatment allowed to obtain high-quality eggs with hatching rates of over 83 %. Sig...

Morphological evidence for the physiological nature of follicular atresia in veiled chameleons (Chamaeleo calyptratus)
Anim Reprod Sci. 2024 Feb;261:107409. doi: 10.1016/j.anireprosci.2023.107409. Epub 2023 Dec 31.ABSTRACTFollicular atresia (FA) has been assumed to serve different functions in reptiles, e.g. helping to develop hierarchies, limiting clutch size, and regression of ovarian structures. Reproductive output is dependent on a balance between ovulations and FA. Excessive rates of FA may not only be detrimental for the survival of a population, but have also been associated with pathological conditions. In order to gain insights into the physiological and potentially pathological processes of FA, we performed a decriptive study on ...
