“…Salisbury and Vandemark (1985) showed that the sperm concentration will follow sexual development and maturity, reproductive health, size of the testes, age, quality of feed given and frequency of ejaculation. The average sperm concentration of Bali bull in this research is in accordance with Ax et al (2008b) who stated that the sperm concentration is at least 1,000 million/mL.…”

“…For better result of artificial insemination, the semen at least contains 60% to 75% sperm motility (Ax et al (2008a), sperm mass movement minimum value 2+ (Argiris et al, 2017) and sperm abnormality ≤ 20% (Menon et al, 2011). In cattle, the normal volume was 7 to 10 mL per ejaculate with sperm concentration was 1000×10 6 to 1500×10 6 sperm/mL (Ax et al, 2008b).…”

The aim of this research was to analyze the correlation of age of Bali bull to the body weight and semen qualities. The materials were 50 Balibulls data collected from 2012 to 2018. Therecordeddatawere consisted ofsemen productions (n = 1304) and body weight (n = 1544). The observation was conducted to analysis the interrelationship between the Bali bulls age and body weight (BW), to the semen volume (SV), individual motility (IM) and sperm concentration (SC). The obtained data was analyzed with One-Way ANOVA analysisby using SPSS 24 and followed with Duncan’s Multiple Range Test to determine any significant differences. The correlation between Bali bulls age (the independent variable) and semen quality (the dependent variable) was computed by using Pearson correlation method and presented in linear regression models. The results showed that the Bali bulls agesignificantly affect (P<0.05) the BW from the age of 1 to 10 years old. The age also showed a significant effect (P<0.05) on the semen qualities. The age correlated significantly (P<0.05) with BW, SV, IM, SC were 0.658, 0.386, 0.134 and 0.086, respectively. Inconclusion,the age of Bali bull could be used as an indicator todetermineits BWand semenqualities.

“…Similarly, this difference was not statistically significant between groups throughout the experiment. Semen volume is one of the important factors in semen evaluation and reproductive performance in the males (Ax et al, 2000). Although, the differences obtained were not statistically different, semen volume and sperm motility values obtained in this study were respectively lower than the corresponding values reported by Nour et al (1981) for adult Katjang and Katjang x German Fawn goats.…”

In the tropics, ruminants are raised on natural pastures which decline rapidly in quality and quantity during the dry season. This study assessed the reproductive performance of rams fed with cassavapeel-silage (CPS) blended with pineapple-waste (PW) on: scrotal circumference, testicular size and semen volume. Randomized complete block design with four treatments of PW at 0, 20, 40 and 60% w/w in Diets 1, 2, 3 and 4 were used. Each treatment had three replicates while semen was collected once from all replicates in the treatments. Rams were fed experimental diets for 56 days. Cassava-peel was substituted with PW at 0, 20, 40 and 60% w/w in Diets 1, 2, 3 and 4 respectively. Fresh PW were ensiled in plastic mini silos. Samples of freshly processed pineapple waste were taken on the day of ensiling and ensiled products were opened after 21 days to determine their nutritive value. All silage blends had colours from brown to yellow with pH values from 4.0 to 6.8. The scrotal diameter from 16.00cm to 21.40cm and scrotal length from 8.83cm and 12.75cm but did not differ significantly (P>0.05). The sperm motility of rams fed diets 4 and 1 was similar to rams fed other diets. Mean sperm volume, percentage livability and percentage sperm morphology were similar across treatments (P>0.05). It can be concluded that CPS blended with PW up to 60% showed no adverse effect on semen characteristics and fertility of the rams.

“…However, this technique should be avoided, since it can transmit defects to their offspring, which are not observed during the collection process, such as failure or lack of sexual interest, weakness of legs, erectile dysfunction, among others. In addition, the electro-ejaculation not always culminates in the production of an ejaculate; these are of lesser quality and induces stress in animals (160) , generating considerations concerning the welfare of the same. It has been shown that during electro-ejaculation, the electricity applied induces important changes in heart rate and levels of cortisol (161) , so it has been banned in some countries (162) .…”

“…Sin embargo, esta técnica debe evitarse, debido a que puede transmitir defectos a sus crías, que no se observan durante el proceso de colección, como son: la falta o poco interés sexual, debilidad de patas, problemas de erección, entre otros. Además, la electro-eyaculación no siempre culmina en la producción de un eyaculado; estos son de menor calidad que los obtenidos con vagina artificial y la técnica produce elevados índices de estrés en los animales (160) , generando consideraciones sobre el bienestar de los mismos. Se ha demostrado que durante la electo-eyaculación, la electricidad aplicada induce cambios relevantes en la frecuencia cardiaca y niveles de cortisol de los carneros (161) , por lo que se ha prohibido su uso en algunos países (162) .…”

RESUMENEl presente trabajo tiene como objetivo recapitular la literatura disponible sobre factores que influyen en la conducta sexual del carnero. Incluye una descripción de los fundamentos endocrinos básicos, su manifestación en borregos ferales, así como una breve reseña de las conductas de cortejo y cópula. También abarca una descripción de aquellos efectos que tanto a nivel prenatal como durante la infancia pueden afectar la vida reproductiva del animal adulto, considerando prácticas de manejo tales como la separación por sexos al momento del destete, y los problemas posteriores de homosexualidad o inadecuda conducta sexual que pueden mostrar en su madurez. Además, se revisan aspectos de dominacia y fotoperiodo, y cómo estos pueden afectar el éxito reproductivo. Se describen aspectos relacionados con la selección del compañero de monta y colección del semen. Finalmente, se documentan algunas pruebas a corral, desarrolladas con el fin de determinar cuáles son los carneros que pueden tener mayor éxito reproductivo en condiciones de campo.PALABRAS CLAVE: Comportamiento reproductivo, Ovinos, Reproducción, Libido, Capacidad de servicio. ABSTRACTThe purpose of this manuscript is to summarize the literature regarding factors influencing rams' sexual behavior. It includes a description of: the fundamental endocrine basis of sexual behavior, its manifestation in feral sheep, a brief description of ram´s courting, and copulatory behaviors. It also describes how some prenatal and childhood conditions can impact reproductive performance in mature animals, in addition to management practices, such as separation by sexes at weaning, and the later problems of homosexuality or inadequate sexual behavior that might some rams develope. Furthermore, the effects of dominance and photoperiod, and their effect in the reproductive success, together with some aspects related to mate selection are also described. Some considerations during semen collection are stated as well, and finally, several useful tests that have been developed under pen conditions to determine which rams could be successful breeders in the field are illustrated.
