“…The reduced libido scores recorded for the goats treated with MSG in this study may have been due to their lowered serum levels of testosterone (Chenoweth 1981), as all other parameters and factors apart from MSG doses and routes of administration were equally applicable to all. The finding of reduced libido in the WAD bucks treated with MSG in this study tends to validate the traditional or folkloric use of MSG by the Nigerian Fulani animal growers in "knocking out libido" and castration of bucks (Igwebuike et al 2011).…”

“…The real reproductive ability of males can be indirectly determined by libido, which is the degree of interest of the male to copulate (Chenoweth, 1981). According to the classification of Chemineau et al (1991), for small ruminants, libido can be evaluated by reaction time (seconds).…”

Seasonal variation in the reproductive activity of male goats raised under tropical climate conditions

-This study analyzed seasonal variations in the testes, the concentration of sex hormones, the parameters of fresh and thawed semen, and the sexual behavior of male Alpine goats from a temperate region in a tropical climate and possible interference with fertility. The maximum and minimum temperature and luminosity were recorded daily, while seminal, hormonal, and behavioral assessments were carried out every fortnight. The maximum and minimum temperature (°C) and luminosity (h) were recorded daily always at 17.00 h. The scrotal circumference (cm), testicular volume (mL), volume (mL), appearance (creamy, milky, aqueous) and coloration (white, white-yellowish, and yellowish) seminal, turbulence or mass movement (0 to 5), progressive spermatic motility (0 to 100%), spermatic force (0 to 5), concentration (spermatozoids/mL), spermatic pathologies, hypoosmotic test (%), serum levels of FSH (mUI/mL), LH (mUI/mL), testosterone (ng/mL), and sexual behaviors were carried out every fortnight. There was a difference between the scrotal circumference evaluated monthly, testicular volume, volume and concentration of fresh semen, sperm vigor of the thawed semen, serum levels of testosterone, FSH and LH, and some sexual behaviors. Thus, the changes that occur in the quantity and quality of sperm, in the hormonal profile, and in sexual behaviors should not be regarded as an impediment to the use of male Alpine goats in tropical climates throughout the year. These variations do not lead to changes in the semen that may compromise the fertility of these animals.

“…Whilst Galal et al (1978) with seasonal studying on Merino, Ossimi and their crosses stated that relationship between semen quality and libido is not clear across breeding groups. This incoherence in results of different probers may be due to various methods of testing libido, such as the latency for males to copulate, or reaction time (Chenoweth, 1981;Landaeta-Hernandez et al, 2001) counts and durations of interest, such as sniffing at the vulva and time spent with females ) the number of mounts and/or serves during a specified period of time (Landaeta-Hernandez et al, 2001;Bertram et al, 2002), and scores assigned according to various combinations of these measures (Chenoweth, 1981;LandaetaHernandez et al 2001). On the other hand, sexual activity of males is influenced by the test conditions and the methods applied in tests can vary considerably, even within the same experiment.…”

This study was conducted on 10 crossbred rams consisted of 5 ArkharMerino×Moghani (AM×MG) and 5 Baluchi×Moghani (BL×MG), to analyze correlation between semen characteristics and libido activity. The semen samples were evaluated for semen volume, total sperm per ejaculate (TSE), spermatozoa concentration (SC), color, wave motion, spermatozoa progressive motility, percentage of live and abnormal spermatozoa, pH, rate of metabolic activity of spermatozoa and semen index. The libido of rams was measured by two indices including reaction time (RT) and refractory period (RP). While RT only had a negative and significant correlation with semen volume (r=-0.15, P=0.04), but RP had a significant correlation with seminal traits except for TSE. Moreover, libido test scores between two genetic groups did not have a significant difference (P<0.05). Considering the observed significant correlation between RP and semen characteristics, we suggest that a reliable monitoring with the aim of detecting rams of poor semen quality and libido seems worth making an effort for the future of the herd. In summary, the reported correlation between libido and seminal traits will confirm the importance of simultaneous selection for both libido and semen quality in the herd. Finally, the importance of performing an individual evaluation of semen and libido for each male and for using a ram in breeding programs is highlighted, due to the existence of differences among rams as well as a low correlation between semen characteristics and libido indices.
