Avaliaram-se os parâmetros seminais e testiculares de 17 carneiros (cinco Santa Inês, cinco Dorper e sete mestiços ¾ Dorper + ¼ Santa Inês). A coleta de dados foi realizada quinzenalmente. Os ejaculados foram colhidos em vagina artificial, mantidos em banho-maria (37 °C) e avaliados quanto ao volume, aspecto, vigor, motilidade, turbilhonamento, concentração, morfologia e viabilidade espermática. Houve diferença significativa (P <0,05) entre as raças para perímetro escrotal, temperatura retal e algumas das características seminais. O volume do ejaculado foi maior (P <0,05) na Dorper (1,27 ± 0,1 ml) comparado à Santa Inês (0,81 ± 0,1 ml) e mestiços (1,00 ± 0,1 ml). A motilidade espermática foi significativamente maior nos carneiros Santa Inês e...

Características seminales de verracos alimentados con dietas adicionadas con ácido linoleico conjugado o nucleótidos, y comportamiento sexual de verracos castrados tratados con PGF2α.

Características seminales de verracos alimentados con dietas adicionadas con ácido linoleico conjugado o nucleótidos, y comportamiento sexual de verracos castrados tratados con PGF2α.

Zamora Zamora, Vicente.

La composición nutrimental de la dieta afecta las características del semen y composición de nutrientes del espermatozoide. El comportamiento sexual en machos no está completamente relacionado con las hormonas esteroides producidas en el testículo. Se realizaron dos experimentos para evaluar el potencial de la adición de ácido linoleico conjugado (ALC; experimento 1) o nucleótidos (experimento 2) a dietas para verracos para mejorar las características seminales y modificar el perfil de ácidos grasos del espermatozoide. Adicionalmente se evaluó el comportamiento sexual y concentración de hormonas específicas en verracos castrados tratados con PGF2α (experimento 3). En el experimento 1, los tratamientos evaluados fueron: T1) Dieta testigo y T2) Dieta con 1%...

There is little information on the nutrition of red-winged tinamous (Rhynchotus rufescens) reared in captivity, and their nutritional requirements still need to be determined. This study aimed at determining dietary crude protein requirements and testing four organic selenium supplementation levels in the diet of red-winged tinamous during the breeding season. Birds were housed in a conventional broiler house divided in 16 boxes with one male and three females each. Iso-energy (2800kcal ME/kg) pelleted feeds, based on corn and soybean meal, were supplied in tube feeders. In the first experiment, treatments consisted of four different diets containing different crude protein (CP) contents (15, 18, 21, or 24%) and in the second experiment, the four diets...

El fotoperiodo y su relación con la reproduccón del venado cola blanca (Odocoileus virginianus miquihuanensis) en el Altiplano Potosino.

Arenas Baéz, Pablo.

En México el venado cola blanca es la especie más importante en la actividad cinegética por su derrama económica, lo que ha motivado a manipular la reproducción de esta especie para garantizar su conservación y aprovechamiento sustentable en el territorio nacional. Por tal motivo se llevó a cabo la presente investigación con el objetivo de definir la época reproductiva del venado cola blanca (O. v. miquihuanensis) en el Altiplano Potosino, la calidad de semen, la relación del fotoperiodo en la producción y la calidad de semen, y generar un índice de calidad de semen de venado. Se utilizaron 3 venados machos adultos con edades de 3½, 4½ y 6½. La obtención del semen se realizó mensualmente por electro-eyaculación, y fue evaluado en base a motilidad masal...

We used 550 Braford and 214 Brangus-Ibagé bulls to study the association between Y chromosome morphology and the evaluation of breeding-soundness, karyotyping and breeding records were used to assess Y chromosome morphology. In general, no direct association was detected between the individual type of Y chromosome and reproductive fitness as previously estimated through breeding soundness examination. The type of breeding strategy used to form the synthetic breeds was also analyzed. The Braford breed is about 3/8 Zebu (Bos taurus indicus) and 5/8 Hereford (Bos taurus taurus) but when the breeding strategy used 1/4 Zebu animals to produce Braford bulls which were 3/8 Zebu a greater percentage of the bulls had to be culled due to reproductive problems. Our...

The objective of this study was to evaluate the effects of season, natural photoperiod, and room temperature at the housing facility on boar semen characteristics in Uruguay (34º66'S; 56º29'W). For this purpose, 117 ejaculates, obtained from eight adult males collected through 12 consecutive months, were assessed for sperm viability, DNA integrity, abnormalities (total, primary, and secondary), ejaculate volume, and sperm concentration. Viability, total and primary abnormalities, volume, and sperm concentration were affected by season. Sperm viability, volume, and sperm concentration were affected by natural photoperiod. In general, autumn and the decreasing photoperiod had a negative impact on most of the semen characteristics, except for volume. Housing...

ABSTRACT 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...

It is believed that increased livestock production is limited by tropical climate. Thermal imbalance in bulls can lead to hyperthermia and alter testicularmetabolism, causing subfertility or infertility. Therefore, the thermoregulation of composite Canchim bulls (5/8 Charolais × 3/8 Zebu) raised in tropical climate as well as their consequences in the physiological, hematological, hormonal, and andrological parameters were evaluated monthly. The bulls (n = 18; 30.0 ± 1.5 months; 503.8 ± 23.0 kg) were kept on pasture, in a single group, from August 2015 to March 2016, comprising the winter, spring, and summer seasons. Biometeorological variables were continuously monitored, and the Temperature and Humidity Index (THI) was calculated. A greater thermal...
