Abstract: The success of cloning animal paves a new way to increase livestock production and conserve genetic resources. After the success of first cloned pig production, a large number of research reports related to cloned pig have been published. However, a few researches into reproductive ability of cloned pig were conducted. The evaluation of reproductive performance of cloning pig is of great importance in practical application for breeding and reproduction. The purpose of present study was to compare reproductive performance of cloned Large White boars with non-clones. First, cloned pigs were produced by somatic cell nuclear transfer (SCNT) technique. After confirmation of cloning success, two groups (clones versus non-clones) were created for a comparison. The semen quality and reproductive performance of pigs derived from SCNT were tested. Growth performance of their progeny was also compared. The results showed that there were no significant differences in semen quality and reproductive performance between clones and non-clones. The parameters related to growth performance such as weight and average daily gain were similar in both groups. To sum up, no remarkable differences were observed between clones and non-clones, indicating that SCNT technology could be applied not only to increase swine production but also to preserve and spread superior Large White pig species.

Abstract: In recent years, the increasing awareness of health benefits associated with natural oils has led to a burgeoning demand for seed oils of plants such as hibiscus. This plant is well known for the richness of its oil in nutritional and bioactive compounds used in medicine and cosmetics. Oil extraction is one of the most critical steps in seed oil production, because it is linked to the quality and the quantity of the extracted oil. These processes play a pivotal role in ensuring the production of high quality of vegetable oils derived from seeds. Cold press oil extraction is more environment friendly than other oil extraction methods as it preserves the natural flavor, aroma, and nutritional content of the oil. Here, the cold pressing method was used to optimize oil pressing from hibiscus seeds. The carefully selected and dried seeds were directly introduced into a semi-automatic device consisting of a cylindrical screw press at approximately 50°C, which allowed the oil and seeds to be recovered separately. The collected oil is then left to settle overnight before being filtered and stored in clean, dry containers. The oil content of the seeds was evaluated by comparing the mass of virgin oil obtained with that of the crushed seeds and gave a yield of about 17.87%. The natural and harmless potential of this traditionally pressed hibiscus oil allows it to contribute to the prevention of many diseases and to promote human health and well-being. At the same time, many by-products, including oilseed cakes, were obtained, constituting a basic feed for animals.
