Influence of commercial inactivated or modified-live virus vaccination at time of AI on corpus luteum development and function in beef cattle
Our objective was to evaluate the effect of vaccination with an inactivated virus vaccine (IVV) or modified-live virus (MLV) vaccine on the corpus luteum (CL). On d0, synchronized beef cows were treated with MLV (n = 70; BoviShield Gold FP5VL5), IVV (n = 16; ViraShield 6VL5HB), or were unvaccinated controls (n = 5). Plasma was collected from treated animals on d0 and every other day through d22. Plasma was analyzed for concentrations of progesterone and 15 cytokines. Between d10 and d13, selected females (n = 13) were ovariectomized; controls were slaughtered on d15/16 to obtain CL for histological evaluation. There were reduced numbers of large luteal cells (LLC) in MLV compared to IVV and controls (P < 0.0001), but IVV were similar to controls (P = 0.11). MLV had decreased LLC percentage compared to controls, and IVV were intermediate (P < 0.0001, MLV: 1.57 ± 0.33 %, IVV: 2.99 ± 0.30 %, Control: 6.45 ± 0.33 %). Based on progesterone concentrations, 24 % MLV and 0 % IVV had an abnormal cycle following vaccination. Overall, MLV had reduced progesterone concentrations (P = 0.02; MLV: 3.61 ± 0.22; IVV: 4.81 ± 0.46 ng/mL). The new CL that formed following an abnormal cycle in MLV had the greatest percentage (35.56 ± 5.5 %) of apoptotic cells. Treatment by cycle status interaction, and time significantly affected IFN-γ, IP-10, MIP-1β, and MCP-1 (P < 0.03), with several time points having elevated concentrations in abnormally cycling MLV animals. Collectively, this demonstrates MLV vaccination around estrus negatively influenced LLC, progesterone, and increased luteal apoptosis and pro-inflammatory cytokines.
期刊介绍：
Animal Reproduction Science publishes results from studies relating to reproduction and fertility in animals. This includes both fundamental research and applied studies, including management practices that increase our understanding of the biology and manipulation of reproduction. Manuscripts should go into depth in the mechanisms involved in the research reported, rather than a give a mere description of findings. The focus is on animals that are useful to humans including food- and fibre-producing; companion/recreational; captive; and endangered species including zoo animals, but excluding laboratory animals unless the results of the study provide new information that impacts the basic understanding of the biology or manipulation of reproduction.
The journal''s scope includes the study of reproductive physiology and endocrinology, reproductive cycles, natural and artificial control of reproduction, preservation and use of gametes and embryos, pregnancy and parturition, infertility and sterility, diagnostic and therapeutic techniques.
The Editorial Board of Animal Reproduction Science has decided not to publish papers in which there is an exclusive examination of the in vitro development of oocytes and embryos; however, there will be consideration of papers that include in vitro studies where the source of the oocytes and/or development of the embryos beyond the blastocyst stage is part of the experimental design.
