Effect of artificial insemination with fresh semen, with one and two services, on the fertility and natality of alpacas

Descripción del Articulo

The aim of this study was to evaluate the pregnancy and natality rate of artificial insemination (AI) in alpacas, using fresh semen, with one and two services, in Cusco, Peru. Semen from 10 alpacas was collected by the post-copula method between January and March, using ejaculates that had volume ≥1...

dc.description.none.fl_txt_mv The aim of this study was to evaluate the pregnancy and natality rate of artificial insemination (AI) in alpacas, using fresh semen, with one and two services, in Cusco, Peru. Semen from 10 alpacas was collected by the post-copula method between January and March, using ejaculates that had volume ≥1 ml, motility ≥60% and light red or creamy white color. The ejaculates were diluted in Tris-glucose and egg yolk at a concentration of 20%. For AI, alpacas with history of previous births, ≥20-day post-partum and body condition ≥3, receptive to the male and with a preovulatory follicle ≥7 mm were selected. The induction of ovulation was done with the administration of 80 μg buserelin/animal. The females were inseminated 26-30 h after the induction of ovulation, with diluted fresh semen (1 ml with 25x106 spermatozoa), deposited inside the body of the uterus. The diagnosis of pregnancy was determined at 30 days of service and natality at parturition. Of 200 alpacas inseminated with one service, 50.5% of pregnancy and 46% natality rate were obtained. Likewise, the 99 alpacas that did not conceive at the first service were inseminated for the second time, obtaining 45.5% of pregnancy and 38.4 natality. At the end of the campaign, with 1 or 2 services, 73% of pregnancies and 65% of births were obtained. The high pregnancy and birth rates obtained when inseminating with fresh semen, with one and two services make this technique eligible for use in commercial herds.
El objetivo del estudio fue evaluar los porcentajes de preñez y natalidad de la inseminación artificial en alpacas con semen fresco, con uno y dos servicios, en Cusco, Perú. Se colectó semen de 10 alpacas mediante el método poscópula entre enero y marzo, utilizando los eyaculados que tenían volumen ≥1 ml, motilidad ≥ 60% y color rojo claro o blanco cremoso. Los eyaculados fueron diluidos en Tris-glucosa y yema de huevo a una concentración de 20%. Para la inseminación, se seleccionaron alpacas con historia de partos previos, descanso de ≥20 días posparto y condición corporal ≥3, receptivas al macho y con folículo preovulatorio ≥7 mm. Se hizo la inducción de la ovulación con la administración de 80 µg buserelina/animal. Las alpacas fueron inseminadas a las 26-30 h de la inducción de la ovulación, con semen fresco diluido (1 ml con 25 x 106 espermatozoides), depositado dentro del cuerpo del útero. El diagnóstico de preñez se determinó a los 30 días del servicio y la natalidad a la parición. De 200 alpacas inseminadas con un servicio se obtuvo 50.5% de preñez y 46% de natalidad. De igual manera, las 99 alpacas que quedaron vacías al primer servicio fueron inseminadas por segunda vez obteniéndose 45.5% de preñez y 38.4 de natalidad. Al término de la campaña, con 1 o 2 servicios se logró obtener 73% de preñez y 65% de natalidad. Las altas tasas de preñez y natalidad obtenidas al inseminar con semen fresco, con uno y dos servicios hacen elegible esta técnica para su empleo en rebaños de productores.
