Application of multivariate discriminant analysis for differentiation between Saudi sheep () breeds based on physical and histochemical meat characteristics.

Background And Aim: The multivariate discriminant (MVD) analysis was a successful statistical tool with a discriminatory capacity for tracing sheep breeds based on meat characteristics. Thus, this study aimed to identify three Saudi sheep breeds based on the physical and histochemical aspects of meat using MVD analysis.

Materials And Methods: Eight male lambs from each breed, Najdi, Neami, and Harri, were selected randomly at 90 days of age and allocated into three groups for breeding in a completely randomized design.

The wild species genome ancestry of domestic chickens.

Background: Hybridisation and introgression play key roles in the evolutionary history of animal species. They are commonly observed within several orders in wild birds. The domestic chicken Gallus gallus domesticus is the most common livestock species.

Genetic origin of goat populations in Oman revealed by mitochondrial DNA analysis.

The Sultanate of Oman has a complex mosaic of livestock species and production systems, but the genetic diversity, demographic history or origins of these Omani animals has not been expensively studied. Goats might constitute one of the most abundant and important domestic livestock species since the Neolithic transition. Here, we examined the genetic diversity, origin, population structure and demographic history of Omani goats.

Dynamic of Bacterial Diversity in Ileum Digesta Under Water Supplements of Antibiotics and Probiotics.

Background And Objective: Intestinal bacteria plays an important role in the physiological and immunological status of birds. The present study investigated the diversity of intestinal bacterial of broilers that were fed corn-soy diet and supplements of antibiotics and probiotics.

Materials And Methods: The supplemented treatments were water, water with antibiotics, water with probiotic and water with antibiotics and probiotic.

The differentiation of camel breeds based on meat measurements using discriminant analysis.

The meat productivity of camel in the tropics is still under investigation for identification of better meat breed or type. Therefore, four one-humped Saudi Arabian (SA) camel breeds, Majaheem, Maghateer, Hamrah, and Safrah were experimented in order to differentiate them from each other based on meat measurements. The measurements were biometrical meat traits measured on six intact males from each breed.
