DESIGN OF EQUIPMENT AND INSTRUMENTS FOR THE COLLECTION AND PRESERVATION OF SEMEN IN ALPACA (Vicugna pacos)

Abstract

The research was conducted in the laboratory stage on the Granja Agropecuaria de Yauris of the Universidad Nacional del Centro del Peru, located at 3316 mosl, 2 km from Huancayo city, located in El Tambo district, Huancayo province, department of Junín. and field stage in the Communal Enterprise Santo Domingo de Cachi, Yanacancha district of the department of Junin. Among the issues of assisted reproduction in animals is the best collection, representative and repetitive of the ejaculate. Are there adequate equipments and instruments for the collection of sperm in alpacas for conservating and subsequent use of artificial systems such as artificial insemination? The stated hypothesis was: There are adequate equipments and instruments to the sui generis nature of the copula for alpaca semen quality and quantity. General objetive: Design equipments and instruments for the collection of semen in male alpacas for subsequent use in artificial insemination programs. Specific purpose: a) Design an electroeyaculador (EE) for semen collection in alpacas, b) Design an electrical frazadilla for semen collection by artificial vagina (Vate) c) evaluate some characteristics of both seminal collection methods of semen. The findings were as follows: The characteristics of semen obtained are affected by the method of collection employed. We collected semen from the male alpaca by the method of collection by artificial vagina covered with thermo-electric frazadilla in part, not all males responded to this method of collection of semen. Jaiñu semen was collected by hand after electroeyaculación poultry, and stimulation of urine administration of Xylazine hydrochloride (sedative) 0.25 - 1.5 ml/100 kg pv The collection of semen with Vate was performed in 04 males. Collected 16 samples of semen and the following results: the average volume was 1.6 ± 0.8 ml, with values of 0.2 to 2 ml, the average pH was 7.5 ± 0.2, with extreme values of 7.2 and 8.0. Motility was characterized by an oscillatory movement without masal motility for semen collection with electro ejaculated (EE), the average volume was 2.73 ± 0.8 ml, with values ranging from 0.2 to 3 3 ml, the average pH was 7.2 ± 0.21, with values ranging between 7.0 and 8.0, the average life was 72.3 ± 21.9%, with values ranging from 0% and 80% motility rate 0 ranged between 20 and 100, reaching an average of 60.5 ± 23.4%; type 1 the average motility was 21.7 ± 15.7%, with values ranging between 0% and 62%, the average motility rate 2 was 10.4 ± 11.9%, with extreme values of 0 and 64.2%. The average for the vitality of type 3 was 7.4 ± 9.3%, with extreme values of 0 and 31.7, must be validated.
