Sperm collection by electroejaculation in small ruminants: A review on welfare problems and alternative techniques.

Anim Reprod Sci 2019 Mar 29. Epub 2019 Mar 29.

Departamento de Fisiología, Facultad de Veterinaria, Universidad de la República, Lasplaces 1620, Montevideo, 11600, Uruguay. Electronic address:

There are different perspectives on whether there should be use of electroejaculation (EE) for semen collection because it can be stressful and painful for the males when this technique is imposed. In the present review it is examined 1) the effects of EE on animal welfare and semen quality in domestic and wild small ruminants, 2) benefits and limitations of administering anaesthetics and sedatives prior to EE, 3) advantages/disadvantages of transrectal ultrasonic-guided massage of the accessory sex glands (TUMASG) as an alternative to EE, and 4) benefits of administering hormones, such as oxytocin or PGF2α analogues (which stimulate the contractility of the male accessory sex glands), prior to EE and TUMASG. In general, the administration of anaesthetics, sedatives or hormones reduces the pain and stress caused by EE, and can improve sperm quality, but results may vary depending on the species.

Electronic address:

Results of previous studies indicated the existence of LPXRFa, the piscine ortholog of gonadotropin-inhibitory hormone (GnIH), and kisspeptin (Kiss2) in tongue sole (Cynoglossus semilaevis), and that LPXRFa exerts an inhibitory effect on Kiss2 activation in the protein kinase A (PKA) pathway. The functions in the control of reproduction and whether LPXRFa antagonizes the action of Kiss2 by inhibiting the protein kinase C (PKC) pathway, however, are still unknown. In the present study, there was an initial investigation of the direct effects of LPXRFa and Kiss2 on relative abundance of pituitary hormone mRNA transcripts using a whole pituitary culture system.

Analyses of mathematical models for Yangzhou geese egg-laying curves.

Anim Reprod Sci 2019 Apr 8;203:10-24. Epub 2019 Feb 8.

College of Engineering, Nanjing Agricultural University, Nanjing, 210031, China.

Mathematical models of the egg-laying curves for Yangzhou geese exposed to both natural and artificial photoperiods were established to optimise the parameters for maximising geese reproductive performance and for the development of precision feeding methods. With the natural photoperiod, egg-laying starts in autumn when daily photoperiod decreases, but accelerates after the winter solstice, and reaches the peak in spring when photoperiod increases. An accumulating model was constructed based on the hypothesis that the egg-laying capacity of geese was determined by two components of the photoperiod: photo-stimulation and photo-inhibition.

Electronic address:

In vitro embryo production depends on oocyte competence, which is acquired during folliculogenesis, involving cytoplasmic and nuclear processes. In vitro maturation (IVM) induces spontaneous resumption of meiosis, preventing full competence acquisition. The incorporation of a pre-IVM phase with supplementation with C-type natriuretic peptide (CNP) and 3-Isobutyl-1-methylxanthine (IBMX) was used with the aim of improving developmental competence of cattle oocytes.
