However, possible disadvantages of using egg yolk, such as great variability of composition and the risk
of microbiological contamination, have also been pointed out [21].
Furthermore, it has been reported that addition of egg yolk reduces
the acrosome integrity and the post-thawing viability of ejaculated
spermatozoa in several species, such as goats [4, 5], rams [1] and
water buffaloes [6]. Our recent study [15] showed that a semen
extender containing10% BSA without egg yolk resulted in acceptable
fertility that is similar to that achieved with extender
containing egg yolk (63 and 67% lambing rates for BSA- and egg
yolk-containing extenders, respectively). Although addition of
BSA demonstrated to develop a synthetic, semi-defined semen
extender in place of egg yolk, complete elimination of egg yolk or
BSA from semen extender and the use of a non-animal derived
compound, such as a soybean lecithin instead is a better choice for
reducing the hygienic risks of contamination of semen doses with
bacteria and mycoplasma (AndroMed [21] or Biociphos plus [22]).
The present AI trial confirmed the fertility results using a BSAcontaining
extender for freezing ram semen and demonstrated that
a completely defined, synthetic semen extender (AndroMed) could
be used for sheep AI with frozen-thawed semen.

Namun, kemungkinan kerugian dari menggunakan kuning telur, seperti variabilitas besar komposisi dan risiko
kontaminasi mikrobiologi, juga telah menunjukkan [21].
Selain itu, telah dilaporkan bahwa penambahan kuning telur mengurangi
integritas akrosom dan pos- pencairan kelangsungan hidup ejakulasi
spermatozoa pada beberapa spesies, seperti kambing [4, 5], domba [1] dan
kerbau [6]. Kami penelitian terbaru [15] menunjukkan bahwa air mani
extender containing10% BSA tanpa kuning telur mengakibatkan diterima
kesuburan yang mirip dengan yang dicapai dengan extender
kuning telur mengandung (63 dan 67% tingkat beranak untuk BSA- dan telur
kuning mengandung extender, masing-masing ). Meskipun penambahan
BSA menunjukkan untuk mengembangkan sintetis, semen semi-didefinisikan
extender di tempat kuning telur, penghapusan lengkap kuning telur atau
BSA dari semen extender dan penggunaan non-hewani
senyawa, seperti lesitin kedelai bukan merupakan pilihan yang lebih baik untuk
mengurangi risiko kontaminasi higienis dosis semen dengan
bakteri dan Mycoplasma (AndroMed [21] atau Biociphos ditambah [22]).
sidang AI yang hadir menegaskan hasil kesuburan menggunakan BSAcontaining
extender untuk pembekuan semen ram dan menunjukkan bahwa
yang benar-benar didefinisikan, semen sintetis extender (AndroMed) bisa
digunakan untuk domba AI dengan semen beku-dicairkan.
