Effects of cell death-inducing DFF45-like effector B on meat quality traits in Berkshire pigs

Authors: G.E. Yu, S. Kwon, J.H. Hwang, S.M. An, D.H. Park, D.G. Kang, T.W. Kim, I.-S. Kim, H.C. Park, J. Ha and C.W. Kim

Cell death-inducing DFF45-like effector (CIDE) B is a member of the CIDE family of apoptosis-inducing factors. In the present study, we detected a single nucleotide polymorphism (SNP), c.414G>A, which corresponds to the synonymous SNP 414Arg, in CIDE-B in the Berkshire pigs. We also analyzed the relationships between the CI.. Read More»

Cleaning cassava genotypes infected with cassava frogskin disease via in vitro shoot tip culture

Authors: M.J.S. Carvalho, E.J. Oliveira, A.S. Souza, J.S. Pereira, M.S.A.S. Diamantino and S.A.S. Oliveira

This study aimed to develop a methodology for eliminating cassava frogskin disease (CFSD) from in vitro shoot tip culture by associating thermotherapy and tetracycline. Cuttings from different accessions (BGM0232, BGM0315, BGM0464, BGM584, BGM0841, and BGM1342), infected with CFSD according to visual inspection of the disease .. Read More»

Association between single-nucleotide polymorphisms and milk production traits in buffalo

Authors: G.C. Venturini1, D.F. Cardoso1, F. Baldi1, A.C. Freitas1, R.R. Aspilcueta-Borquis1, D.J.A. Santos1, G.M.F. Camargo1, N.B. Stafuzza2, L.G. Albuquerque1 and H. Tonhati1

The aim of this study was to identify single-nucleotide polymorphisms (SNPs) in buffaloes associated with milk yield and content, in addition to somatic cell scores based on the cross-species transferability of SNPs from cattle to buffalo. A total of 15,745 SNPs were analyzed, of which 1562 showed 1% significance and 4742 with 5% significance, which were .. Read More»

Genetic and phenotypic parameters of carcass and organ traits of broiler chickens

Authors: G.C. Venturini1, V.A.R. Cruz1, J.O. Rosa1, F. Baldi1, L. El Faro3, M.C. Ledur2, J.O. Peixoto2 and D.P. Munari1

The objective of this study was to estimate the genetic and environmental parameters for carcass, carcass part, and organ weights in a paternal strain of broiler chickens that was selected mainly for body weight at 42 days of age (BW42) to provide support for poultry genetic improvement programs. A total of 1448 chickens were used that resulted from the e.. Read More»

Sire effects on carcass and meat quality traits of young Nellore bulls

Authors: M.N. Bonin, J.B.S. Ferraz, J.P. Eler, F.M. Rezende, D.C. Cucco, M.E. Carvalho, R.C.G. Silva, R.C. Gomes and E.C.M. Oliveira

Meat quality is being increasingly demanded by consumers in recent years. Several factors can affect meat quality, ranging from animal traits such as breed and genetic heritage to pre- and post-slaughter processes. This study investigated the influence of Nellore bulls on carcass and meat quality traits. We used 475 young unca.. Read More»

Utility of hair shafts from study skins for mitochondrial DNA analysis

Authors: N. Kurihara

The condition of mtDNA in hair shafts preserved in a museum was examined using 30 study skins of masked palm civets, Paguma larvata (Viverridae), collected between 1924 and 2011. Comparisons of extracts from fresh and burnt alum-fixed hair shafts showed that burnt alum, which is commonly used in taxidermy, had no harmful effect on the amount of total DNA .. Read More»

Molecular genetic diversity and maternal origin of Chinese black-bone chicken breeds

Authors: W.Q. Zhu, H.F. Li, J.Y. Wang, J.T. Shu, C.H. Zhu, W.T. Song, C. Song, G.G. Ji and H.X. Liu

Chinese black-bone chickens are valued for the medicinal properties of their meat in traditional Chinese medicine. We investigated the genetic diversity and systematic evolution of Chinese black-bone chicken breeds. We sequenced the DNA of 520 bp of the mitochondrial cyt b gene of nine Chinese black-bone chicken breeds, includ.. Read More»

Experimental evaluation of the reproductive quality of Africanized queen bees (Apis mellifera) on the basis of body weight at emergence

Authors: D.A. De Souza1, M.A.F. Bezzera-Laure1, T.M. Francoy2 and L.S. Gonçalves3,4

There has been much speculation about which phenotypic traits serve as reliable indicators of productivity in queen honeybees (Apis mellifera). To investigate the predictive value of queen body weight on colony development and quality, we compared colonies in which queens weighed less than 180 mg to those in which queens weighed more than 200 mg. Both gro.. Read More»

Comparison of methods for high quantity and quality genomic DNA extraction from raw cow milk

Authors: T. Usman, Y. Yu, C. Liu, Z. Fan and Y. Wang

Isolation of sufficient quantities of high quality DNA is a prerequisite for molecular studies. Milk somatic cells can be used; however, inhibitors such as fats and proteins make milk a difficult medium for extracting large amounts of quality DNA. We optimized, evaluated and compared three methods, Modified Nucleospin Blood Ki.. Read More»

Adjacent SNPs in the transcriptional regulatory region of the FADS2 gene associated with fatty acid and growth traits in chickens

Authors: S.K. Zhu, Y.D. Tian, S. Zhang, Q.X. Chen, Q.Y.Wang,R.L. Han and X.T. Kang

Delta-6 fatty acid desaturases are rate-limiting desaturases involved in metabolic processes of fatty acids, and they are encoded by the FADS2 gene. In the current study, an F2 resource population of Gushi chickens crossed with Anak broilers was used to investigate the genetic effects of the chicken FADS2. Two adjacent single .. Read More»
