IGF-I gene polymorphism, but not its blood concentration, is associated with milk fat and protein in Holstein dairy cows
Authors: E. Bonakdar, H.R. Rahmani, M.A. Edriss and B.E. Sayed Tabatabaei
We estimated the allele and genotype frequencies of IGF-I/SnaBI gene polymorphism and the concentration of this protein in Holstein dairy cows. We also examined the association with milk yield (305-day milk yield) and milk components (fat and protein percentage, and 305-day milk protein and fat yield). Blood IGF-I levels were .. Read More»

Sequence characterization and phylogenetic analysis of toll-like receptor (TLR) 4 gene in the Tibetan macaque (Macaca thibetana)
Authors: Q.X. Dai, Y.F. Yao, Z.C. Qi, Y. Huang, Q.Y. Ni, M.W. Zhang and H.L. Xu
In this study, the complete coding region sequence of an innate immune-related TLR4 gene was obtained from the Tibetan macaque (Macaca thibetana) genome via PCR and direct sequencing. The sequence had a total length of 2481 bp, contained 3 complete exons, and encoded 826 amino acids (AAs); its isoelectric point was 5.703, and the molecular weight was 94.7.. Read More»

â??Ovar-Mhcâ?? - ovine major histocompatibility complex: structure and gene polymorphisms
Authors: V.S.R. Dukkipati, H.T. Blair, D.J. Garrick and A. Murray
The major histocompatibility complex (MHC) in sheep, Ovar-Mhc, is poorly characterised, when compared to other domestic animals. However, its basic structure is similar to that of other mammals, comprising class I, II and III regions. Currently, there is evidence for the existence of four class I loci. The class II region is b.. Read More»

Phylogenetic analysis of Gansu sheeppox virus isolates based on P32, GPCR, and RPO30 genes
Authors: H.L. Su, H.J. Jia, C. Yin, Z.Z. Jing, X.N. Luo and Y.X. Chen
Two outbreaks of sheeppox in sheep have occurred in Gansu Province, China. The P32, GPCR, and RPO30 genes were used as markers for differential diagnosis. We confirmed that the outbreaks were caused by sheeppox virus. Sequence and phylogenetic analysis of the P32, GPCR, and RPO30 genes revealed a close relationship between the 2 isolates and Chinese sheep.. Read More»

Genetic correlation between heifer pregnancy and scrotal circumference measured at 15 and 18 months of age in Nellore cattle
Authors: J.P. Eler, J.B.S. Ferraz, J.C.C. Balieiro, E.C. Mattos and G.B. Mour?£o
Data of pregnancy diagnosis from 24,945 Nellore heifers, raised under tropical conditions in Brazil and exposed to breeding at about 14 months of age, were analyzed simultaneously with 13,742 (analysis 1), 36,091 (analysis 2), 8,405 (analysis 3), and 8,405 (analysis 4) scrotal circumference (SC) records of contemporary young b..

Genetic diversity in wild (Sus scrofa scrofa) and domestic (Sus scrofa domestica) pigs and their hybrids based on polymorphism of a fragment of the D-loop region in the mitochondrial DNA
Authors: S.F. Grossi, J.F. Lui, J.E. Garcia and F.V. Meirelles
We examined the variation in mitochondrial DNA by sequencing the D-loop region in wild and domestic (large-white breed) pigs, in hybrids between domestic and wild pigs, and in Monteiro pigs. A D-loop fragment of approximately 330 bp was amplified by PCR. Sequencing of DNA amplicons identified haplotypes previously described as.. Read More»

Estimates of genetic parameters for Holstein cows for test-day yield traits with a random regression cubic spline model
Authors: DeGroot BJ, Keown JF, Van Vleck LD and Kachman SD
Genetic parameters were estimated with restricted maximum likelihood for individual test-day milk, fat, and protein yields and somatic cell scores with a random regression cubic spline model. Testday records of Holstein cows that calved from 1994 through early 1999 were obtained from Dairy Records Management Systems in Raleigh.. Read More»

Associations between genetic variants in the promoter region of the insulin-like growth factor-1 (IGF1) gene and blood serum IGF1 concentration in Hanwoo cattle
Authors: H.Y. Chung, Y.J. Choi, H.N. Park and M.E. Davis
In this study, we investigated the associations between genetic variants in the promoter region of the insulin-like growth factor-1 (IGF1) gene and blood serum IGF1 concentration in Hanwoo cattle. Polymerase chain reaction primers were based on GenBank accession No. AF404761 and amplified approximately 533-bp segments. Newly identified sequences were subm.. Read More»

Description of electrophoretic and chromatographic hemoglobin profile of Rhinoclemmys punctularia
Authors: Bonini-Domingos CR, Silva MB, Romero RM, Zamaro PJA, Ondei LS, Zago CES, Moreira SB and Salgado CG
Studies of the hemoglobin pattern in Brazilian reptiles are important for determining ecological and phylogenetic relationships, but they are scarce. Peripheral blood samples were obtained from 7 males and 18 females of Rhinoclemmys punctularia. The hematological profile was based on the total hemoglobin and hematocrit values... Read More»

Phylogeography of Brachyplatystoma rousseauxii (Siluriformes - Pimelodidae) in the Amazon Basin offers preliminary evidence for the first case of â??homingâ? for an Amazonian migratory catfish
Authors: J.S. Batista and J.A. Alves-Gomes
The large pimelodid, Brachyplatystoma rousseauxii, is one of the two most important catfish species for the fisheries in the Amazon. It is captured by commercial and artisanal fishing fleets in at least five Amazonian countries, at fishing grounds more than 5000 km apart. Current evidence suggests a complex life cycle that inc..
