Background. Cryopreservation of spermatozoa with the best morphofunctional characteristics may allow their use for assisted reproductive technologies in goat breeding throughout year to effectively increase livestock. Aim. To evaluate influence seasons on morphological and morphometric fresh cryopreserved sperm. Methods. The ejaculate samples three sexually mature bucks Saanen breed were obtain...

There is limited genetic information available in most African goat populations. However, improvements genomic technologies have enabled easy and effective analysis of different parameters. This study used Single Nucleotide Polymorphism (SNP) data four genotypes from Kenya; Galla (n = 12), Alpine 28), Saanen 24) Toggenburger 30). After SNP quality control, 48808 SNPs that were for analysis. Run...

This study was designed to determine the effect of some environmental factors on milk yield and composition in Saanen goats CSN3 AGPAT6 gene polymorphisms production traits. were genotyped for traits, samples collected during lactation, yield/compositions each goat specified. In terms genes, genotypes defined by PCR-RFLP. The (MY), lactation length (LL), protein, fat, total solid (TS), not fat ...

The objective of our work is to identify the different marketing practices and characterize organizational constraints that hinder productivity profitability small-scale livestock farms in mountainous region Fréha Sidi-Naman, located Tizi-Ouzou, Algeria. Due its high milk production potential, targeted was selected as a study area. importance lies determination key factors, which prevent produc...
