Abstract
Simple SummaryGoat production plays an important economic and social role in Northern Moroccan farming. Beni Arouss is an autochthonous North Moroccan goat breed. The use of artificial insemination can largely contribute to optimised preservation and dissemination of valuable traits of this breed and lead to improved productivity. During liquid storage, the stability of semen good quality remains crucial in order to provide greater flexibility between the artificial insemination center and farms where the insemination of does needs to be performed. The study aims to assess the effect of storage and season of the year on fresh semen of Beni Arouss goats. Every month, ejaculates were collected from bucks and were extended and stored at 16 °C for 24 h. Semen motility, viability and normal morphology were assessed at 0, 4, 8 and 24 h after collection. As expected, these parameters showed a significant reduction within 24 h of storage and during all seasons. However, semen collected in summer maintained a better quality after 24 h of storage at 16 °C than semen collected during the other periods. Therefore, the storage ability of Beni Arouss bucks’ semen stored at 16 °C was higher during the summer.The study aimed at determining the effect of storage and season on fresh semen of Beni Arouss goats. Ejaculates were collected at monthly intervals from seven mature bucks and were extended at a final concentration of 800 × 106 spermatozoa. ml-1 and stored at 16 °C for 24 h. Semen motility, viability and normal morphology were assessed at 0, 4, 8 and 24 h after collection. Motility and normal morphology parameters were recorded using computer-assisted sperm analysis (CASA) and viability was analyzed using eosin–nigrosin staining. As expected, motility, viability and normal morphology parameters showed a significant reduction within 24 h of storage and during all seasons (p < 0.05). However, semen collected in summer maintained a better quality after 24 h of storage at 16 °C than semen collected during the other periods (p < 0.05). In conclusion, the storage ability of Beni Arouss bucks’ semen stored at 16 °C was significantly higher during the summer.
Highlights
In the North of Morocco, goat production plays an important social and economic role and represents a live-hood base for 70% of the rural population [1]
In 2007, the food and agriculture organization (FAO) launched the global plan of action for animal genetic resources to strive against the loss of animal genetic diversity and to preserve the zoogenetic resources
The highest velocity results were recorded during summer and autumn (p < 0.05), whereas the lowest progressive motility was recorded during winter (p < 0.05)
Summary
In the North of Morocco, goat production plays an important social and economic role and represents a live-hood base for 70% of the rural population [1]. Low productivity limits the producer’s income [2]. This has led farmers to replace local goats with higher yielding foreign breeds or to perform crossings between local and foreign breeds. This large-scale dissemination of imported dairy goat breeds led to the erosion of indigenous goat genetic resources. Beni Arouss is an autochthonous North Moroccan goat breed, recently recognized by the Moroccan In 2007, the food and agriculture organization (FAO) launched the global plan of action for animal genetic resources to strive against the loss of animal genetic diversity and to preserve the zoogenetic resources.
