BIRD, D. M . , and P. C. LAGUE. 1977. Semen production of the American kestrel. Can. J. Zool. 55: 1351-1358.In 1975, semen was collected by massage from 18 randomly selected captive male American kestrels (Falco sparverius). The period of semen production extended for 103 days, beginning on March 19, while the mean duration of semen production was 73.6 days. Under natural light, semen production began at 123 h of daily light, peaked about 1% h, and decline considerably around June 21 at 153 h. Weather factors, i.e., temperature, barometric pressure, did not significantly (P > 0.05) affect semen collections or quality.The following means were calculated: semen volume, 12 pl; sperm concentration, 31 OOO/mm3; sperm count per ejaculate, 416 000; motility score, 78%; contamination with epithelial debris and urates, 67%; and semen colour, very pale to pale amber.The following significant (P < 0.05) correlations were found: body weight with semen volume (0.48) and sperm count per ejaculate (0.54); egg fertility with sperm count per ejaculate (0.65); semen volume with sperm count per ejaculate (0.84) and sperm motility (0.54); sperm count per ejaculate with sperm concentration (0.78); and sperm motility with sperm concentration (0.59) and sperm count per ejaculate (0.75). BIRD, D. M., et P. C. LAGUE. 1977. Semen production of the American kestrel. Can. J. Zool. 55: 1351-1358. C'est par une methode de massage que nous avons recueilli, en 1975, la semence de 18 miles choisis au hasard au sein d'une colonie en captivite. La production de semence s'echelonna sur 103 jours et dura 73.6 jours en moyenne, et ceci sous illumination naturelle. Les premiers ejaculats ont CtC recueilles le 19 mars sous 123 h de lumiere par jour, la production de semence atteignirent un sommet sous 13) h de lumitre parjour et se mit a diminuer, rapidement vers le 21 juin, sous 153 h de lumitre. Le climat, i.e., temperature, pression atmospherique, n'ont affecte d'une f a~o n significative (P > 0.05) ni les recoltes ni la qualite de la semence. Voici les moyennes calculCes sur les ejaculats: volume, 12 p1; concentration et nombre de spermatozoi'des, 31 OOO/mm3, et 416000, parametre de motilite, 78%, contamination par debris epitheliaux et acide urique, 67%, la couleur va de tres pile a orange pile. Les correlations suivantes se sont avertes significatives ( P < 0.05): poids du mile avec volume (0.48) et nombre de spermatozoi'des par kjaculat (0.54), fertilite avec nombre de spermatozoi'des par ejaculat (0.65), volume de I'ejaculat avec nombre de spermatozoldes par ejaculat (0.84) et motilite (0.54), nombre de spermatozoi'des par ejaculat avec concentration (0.78). motiliti avec concentration (0.59) et nombre de spermatozoi'des par kjaculat (0.75).

“…Semen volume was not significantly related to the fertility data ). In fowl, only two reports of such a correlation exist (Kamar 1960;Kamar and Razik 1973), while most researchers (Shaffner and Andrews 1948 ;McCartney 1956;Boone and Huston 1963;Smyth 1968;Hartmann and Gleichauf 1974) found no evidence of this relationship.…”

“…The deleterious effects of high ambient temperatures on poultry production include reductions in feed intake, gain:feed ratio, growth rate, egg production, egg quality, semen quality, fertility, hatchability of fertile eggs, number of chicks per hen, and bird survival (Boone and Huston, 1963;de Andrade et al, 1974;van Kampen, 1981;Peebles and Brake, 1985;Meltzer, 1986;Muiruri, 1989;Muiruri and Harrison, 1991;McDaniel et al, 1995;Singh, 1999). Heat stress can cause signi cant decreases in rooster fertility due to a decrease in semen quality and the number of sperm penetrating the perivitelline membrane (Clark and Sarakoon, 1967;McDaniel et al, 1995McDaniel et al, , 1996.…”

1. The present study was undertaken to determine the effects of heat exposure on fertility, semen quality, and semen ion concentrations of broiler breeders classified on sperm quality index (SQI) before heat stress. 2. Cobb males (108) were individually caged in 6 temperature-controlled rooms. Each room contained an equal number of males from each of the 4 SQI population quartiles as follows: best (B), good (G), fair (F), and poor (P). Three rooms were heated to 35 degrees C, and the other three rooms were maintained at a constant 23 degrees C as controls. For each SQI group in each room, 15 Leghorn hens were artificially inseminated (5 x 10(7) sperm/hen) once a week for 8 weeks for fertility observations. 3. Body weight, sperm concentration, SQI, and fertility of P males were lower than in the other three SQI groups. Body temperature of the top three SQI groups was increased by heat exposure, but body temperature was not altered by heat stress in the P group. Fertility, sperm viability, and SQI of the top three SQI groups, but not the P group, was decreased by heat stress. Seminal plasma K+ of P males was lower than that of B males. However, seminal plasma Ca2+ concentration of P males was higher than that of B males. 4. In conclusion, high ambient temperatures had more impact on semen quality and fertility of males in the top 75% of the SQI population than in males in the bottom 25% of the population. In addition, calcium ions (Ca2+) appear to play a major role in heat stress infertility.

“…It has long been reported that semen quality is decreased during summer or on exposure to high ambient temperature (Boone and Huston, 1963;Joshi et al, 1980). Though the sperm motility was not affected by heat treatment of broiler males, fertility and sperm egg penetration declined, however, the underlying mechanism is not known (McDaniel et al, 1995).…”
