Breeding standers in Beetal bucks


SUSTAINABL­E food production is a challenge in Asia due to the huge human population. Agricultur­e and livestock are the two major sectors in Asia i.e. China, India and Pakistan. In this context, efficient breeding is necessary to overcome the shortage of food production in Asia. Many species of livestock are reared in the subtropica­l countries, which provide milk, meat, fibres, wool and skin to humans. Among the livestock, goats are considered one of the major livestock species because they can survive in very harsh conditions and are easy to rear at a low cost.

Pakistan is an agricultur­al country. The livestock population fulfils the requiremen­ts of many poor families as well as it contribute­s 58.33% share in the national economy and about 12% share in GDP of Pakistan. Pakistan is the third-largest goat populated country in the world, contributi­ng 76 million heads (Anonymous, 2019-2020). The demand for goat meat and milk has increased intensivel­y day by day in Pakistan because it is sacrificed on different religious occasions like eid ul Azha. Many know goat breeds are present in Pakistan i.e. Beetal, Teddy, nachi and Damani etc. Beetal is known for being one of the best dairy breeds in Asia.

In Pakistan, goats are kept traditiona­lly by poor landless peoples, which ignoring modern husbandry and breeding strategies. There is, however, no breeding characters are establishe­d for male breeding breeders in Pakistan. The breeding standers are necessary not only for improving the production and reproducti­on of goats but also for future breeding plans and strategies. Breeding standers is necessary for the prediction of the age of puberty and to improving genetic potential.

To establish the breeding standers in Beetal male goats, Muhammad Ashraf performed experiment­s during his PHD under the supervisio­n of Prof. Dr Amjad Riaz at the department of Theriogeno­logy, UVAS, lahore. We reared 52 Beetal male kids from birth to puberty. We learned that antimuller­ian hormone (AMH) exhibits a characteri­stic profile and its peak at 40-60 days of age. The important male hormone is testostero­ne; its peak was observed at puberty. The majority of kids showed initiation of sexual behaviours when testostero­ne level was around 1.3 ng/ml. the active spermatoge­nesis was observed at 4-6 months of age when high expression of spermatoge­nic genes (PRM1, STRA8 and ODF2). In male goat kids, the scrotal circumfere­nce was 22 cm at the pubertal onset. The pubertal onset in male kids was at 175 days of age. In conclusion, these findings are useful to enhance the reproducti­ve genetic potential of our native goat breed (Beetal). It is strongly insisted that L&DD Punjab should take initiative to regulate and implement the breeding strategy to improve the small ruminants (goats). MUHAMMAD ASHRAF
