Available in PDF, EPUB and Kindle. Book excerpt: Research presented in this thesis aimed at improving the efficiency of dairy farms through the development of targeted reproductive management strategies (TRM) based on genomically enhanced predictions of fertility, and the elucidation of associations between genetic merit for fertility and biological outcomes that affect dairy cow reproductive performance.Chapter II and III present the results of an experiment designed to compare the association between genetic merit for fertility and reproductive and profitability outcomes of cows submitted for artificial insemination (AI) with management programs that prioritized AI at detected estrus (AIE) or timed AI (TAI). Another objective was to determine if cows with different genetic potential for fertility would present a distinct response to the strategies compared. The study presented in Chapter IV and V characterized associations between genetic merit for fertility and biological parameters known to alter reproductive performance of cows. Results presented in Chapter II and III indicated that primiparous Holstein cows of superior genetic merit for fertility had better reproductive performance than cows of inferior genetic merit for fertility regardless of the type of reproductive management used. In addition, the effect of TRM based on genetic merit for fertility on reproductive performance depended on the outcome or sets of outcomes of interest evaluated. For example, cows of superior and intermediate genetic merit for fertility had greater P/AI when managed with the predominant TAI program but reduced days to pregnancy when managed with the program that prioritized AIE. Cows of inferior fertility also had greater first service P/AI with the program that prioritized TAI but had similar days to pregnancy with both management strategies. From an economic standpoint, cows of inferior fertility had greater cash flow than cows of superior fertility. For cows in specific fertility groups, the effects of the reproductive management strategies compared generated differences in cash flow of potential value for commercial dairy farms. The study presented in Chapter IV and V demonstrated a potential association of genomic merit for fertility with physiological and endocrine parameters known to affect reproductive performance of dairy cows. Particularly, cows of inferior genetic merit for fertility had poorer uterine health, decreased response to synchronization of estrus and ovulation, and were more likely to present altered ovarian and hormonal phenotypes that led to more frequent expression of atypical estrous cycles as compared with cows of superior genetic merit for fertility. Overall, we observed that genetically enhanced predictions of fertility might be a suitable tool for decision making in TRM. Additionally, the value of TRM programs for cows of different genetic merit for fertility might be on improving aspects of herd management such as simplifying program implementation or reducing reliance on hormonal interventions while maintaining acceptable levels of reproductive performance. An improved understanding of biological differences associated with genetic variation, such as our observations in Chapter IV and V, may be beneficial for the development of novel TRM and technologies to improve the reproductive efficiency of dairy cattle. This novel information could also support the development of new traits for selection of fertility.

Available in PDF, EPUB and Kindle. Book excerpt: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases are described. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the studies presented in Section I were to evaluate insemination dynamics, time to pregnancy, and profitability of replacement dairy heifers managed with first service programs that relied primarily on insemination at detected estrus (AIE), timed-artificial insemination (TAI), or a combination of both. The objectives of the experiments presented in Section II were; to develop and validate a tool integrating a disposable fluorescence-based lateral flow immunoassay (LFIA) coupled with a portable imaging device to determine the reproductive status of cows based on circulating progesterone (P4) concentration; to test the efficacy of intravaginal (IVG) administration of prostaglandin-F2_ (PGF) to induce corpus luteum (CL) regression; and to develop and validate an electronically-controlled hormone delivery device for reproductive control of cattle. The studies presented in Section I demonstrated that a reproductive management strategy designed to submit all heifers to TAI reduced time to first AI and time to pregnancy when compared with a strategy that relied primarily on AIE after induction of estrus with PGF treatments. The program that combined AIE and TAI resulted in intermediate performance. In spite of greater reproductive cost, programs that used TAI in combination with AIE or solely TAI reduced rearing cost and generated more revenue during first lactation, which translated in numerically greater cash flow under fixed or simulated market conditions. The first experiment of Section II demonstrated that the developed LFIA system can accurately predict the presence of a functional CL (i.e., P4 ≥ 1 ng/mL) using bovine plasma samples. Additional improvements of this assay may lead to the development of a rapid, low-cost, cow-side tool for determination of reproductive status of cattle. The other experiments presented in Section II demonstrated that two IVG treatments of PGF 12 hours apart resulted in similar luteal regression risk, estrus expression, ovulatory response to GnRH, and pregnancy per AI compared with that observed after a single intramuscular dose of PGF. Further, we demonstrated that the current IVG prototype device for hormone delivery can be programmed to automatically release PGF for successful induction of luteal regression in cattle. Once optimized, the developed IVG device may be an alternative too to the needle-injection methods presently used to synchronize ovulation of cows.
