Effect of semen collection by transrectal massage of accessory sexual glands or artificial vagina on the outcome of breeding soundness examinations of Italian yearling beef bulls

Effect of live weight on libido, sperm quality, testosterone and lute-inizing hormone in replacement stock of Ongole Grade bull

“…The LW of <216 kg caused low libido and low sperm quality.This was in line with Tillman et al, (1998) who also reported that the minimum LW of bulls should be 235 to 292 kg to be able to produce sperm.Thus libido is strongly influenced by the training and LW, which is at least 250 kg for the replacement stock bull. Other factors that can cause low libido or sperm quality include handling that caused stress in bulls (Partodihardjo, 1987), age of bull (Zhan-Xing et al, 2014), semen collection techniques such as transrectal massage and electro-ejaculatory (Ali, 2014;Sylla et al, 2015;Palmer et al, 2015), environmental temperature, season and management (Rasyid et al, 2003;Bhakat et al, 2009;Al-Badry, 2013).…”

“…The high pH values in all groups were due to the use of the electroejaculatory equipment so that all of the semen fluids came out. Sperm collection using transrectal massage (Ali, 2014) and electro-ejaculator techniques (Sylla et al, 2015). Palmer et al (2015) obtained acidity (pH 8.2 ± 0.3).…”

“…Other factors such as the age of the bulls (Zhan-Xing et al, 2014;Farooq et al, 2013), collection technique (i.e. transrectal massage and ejaculator) (Ali, 2014;Sylla et al, 2015;Palmer et al, 2015), environmental temperature, collection, seasons, management (Rasyid et al, 2003;Bhakat et al, 2009;Al-Badry, 2013;Chacur et al, 2013 and the concentrations of hormones (GhRh, LH and testosterone) (Masoumi et al, 2011;Chacur et al,2013) decrease libido and sperm quality. Research needs to be done to improve libido and sperm quality, such as regular sperm collection and improving LW.…”

Semen collection by trans‐rectal digital stimulation and insemination campaign in goat

“…Transrectal digital stimulation was applied in other animal species such as bulls and elephants (Palmer et al, 2005;Schmitt et al, 1998;Sylla, Palombi, Stradaioli, Vagniluca, & Monaci, 2015) as well as in humans by Ibrahim et al, 2016. In terms of fertility results, the pregnancy rate obtained in this study with the use of TDM is found admissible when compared with EE and AV methods (Karatzas, Karagiannidis, Varsakeli, & Brikas, 1997;Leboeuf et al, 1998;Ritar et al, 1992;Ritar & Salamon, 1983). Transrectal digital stimulation was applied in other animal species such as bulls and elephants (Palmer et al, 2005;Schmitt et al, 1998;Sylla, Palombi, Stradaioli, Vagniluca, & Monaci, 2015) as well as in humans by Ibrahim et al, 2016. In terms of fertility results, the pregnancy rate obtained in this study with the use of TDM is found admissible when compared with EE and AV methods (Karatzas, Karagiannidis, Varsakeli, & Brikas, 1997;Leboeuf et al, 1998;Ritar et al, 1992;Ritar & Salamon, 1983).…”

“…In the present study, the semen collection with TDM was suc- the method of massaging the ampullae using a US probe and it was reported that the EE causes a greater increase in cortisol levels although no difference in sperm characteristics than TUMASG. Transrectal digital stimulation was applied in other animal species such as bulls and elephants (Palmer et al, 2005;Schmitt et al, 1998;Sylla, Palombi, Stradaioli, Vagniluca, & Monaci, 2015) as well as in humans by Ibrahim et al, 2016. In terms of fertility results, the pregnancy rate obtained in this study with the use of TDM is found admissible when compared with EE and AV methods (Karatzas, Karagiannidis, Varsakeli, & Brikas, 1997;Leboeuf et al, 1998;Ritar et al, 1992;Ritar & Salamon, 1983). The results of this study also reveal the success and combined applicability of techniques such as out of breeding season synchronisation protocol, infrared thermography for oestrus detection, semen collection via trans-rectal massage and vaginal insemination in goats.…”
