Carcass composition and meat quality of indigenous Yanan pigs of China
Authors: Y.-Z. Jiang, L. Zhu, F.-Q. Li and X.-W. Li
The Yanan (YN) pig is a traditional Chinese indigenous breed that is raised in southwest China in the Sichuan Province, but there is little data on the germplasm characteristics of this breed. To evaluate carcass characteristics and meat quality of the YN pig, we compared carcass and meat quality of YN pigs and Landrace ×.. Read More»

Multiplex PCR panel of microsatellite markers for the tambaqui, Colossoma macropomum, developed as a tool for use in conservation and broodstock management
Authors: I.G. Hamoy and S. Santos
The tambaqui, Colossoma macropomum, native to Brazil, is widely used in aquaculture systems. We developed a multiplex PCR panel for this species, comprising 12 microsatellite loci. This panel was used to genotype 73 specimens collected from Juruti, a city in the Brazilian Amazon. The mean number of alleles per locus was 8.8, t.. Read More»

Genetic and non-genetic effects on productive and reproductive traits of cows in dual-purpose herds in southeastern Mexico
Authors: G.M. Parra-Bracamonte, J.G. Maga�±a, R. Delgado, M.M. Osorio-Arce and J.C. Segura-Correa
Data on productive and reproductive performance of cows in dual-purpose herds were analyzed to determine the effect of some environmental and genetic factors on saleable milk yield (SMY), lactation length (LL), daily saleable milk per lactation (DMYL), calving interval (CI), and daily saleable milk per calving interval (MYCI) ..

Morphology and protein patterns of honey bee drone accessory glands
Authors: Carminda da Cruz Landim and Rodrigo Pires Dallacqua
We used light and transmission electron microscopy to examine the morphology of the accessory glands of immature and mature adult males of Apis mellifera L. We also made an electrophoretic analysis of the protein content of the mature gland. The glands of the immature male actively secrete a mucous substance that can be seen i.. Read More»

Communal use of integumental wounds in honey bee (Apis mellifera) pupae multiply infested by the ectoparasitic mite Varroa destructor
Authors: Ghazwan Kanbar and Wolf Engels
The ectoparasitic bee mite, Varroa destructor, is highly adapted to its natural and adopted honey bee hosts, Apis cerana and Apis mellifera. Adult females perforate the integument of bee pupae in such a way that they and their progeny can feed. We examined the wounds that founder females made, and usually found one, and rarely..

(Co)variance components and genetic parameters for growth traits in Arabi sheep using different animal models
Authors: B. Shokrollahi and H. Baneh
The objective of the present study was to estimate genetic parameters for body weight at different ages in Arabi sheep using data collected from 1999 to 2009. Investigated traits consisted of birth weight (N = 2776), weaning weight (N = 2002) and weight at six months of age (N = 1885). The data were analyzed using restricted m.. Read More»

Effect of pregnancy on the genetic evaluation of dairy cattle
Authors: R.J. Pereira, M.L. Santana Jr., A.B. Bignardi, R.S. Verneque, L. El Faro and L.G. Albuquerque
We investigated the effect of stage of pregnancy on estimates of breeding values for milk yield and milk persistency in Gyr and Holstein dairy cattle in Brazil. Test-day milk yield records were analyzed using random regression models with or without the effect of pregnancy. Models were compared using residual variances, herita.. Read More»

Lack of an association between a single nucleotide polymorphism in the bovine myogenic determination 1 (MyoD1) gene and meat quality traits in indigenous Chinese cattle breeds
Authors: J.A. Ujan, L.S. Zan, H.B. Wang, S.A. Ujan, C. Adoligbe, H.C. Wang and S.F. Biao
The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single n.. Read More»

Genetic analysis of body weights of individually fed beef bulls in South Africa using random regression models
Authors: N.W. Selapa, K.A. Nephawe, A. Maiwashe and D. Norris
The aim of this study was to estimate genetic parameters for body weights of individually fed beef bulls measured at centralized testing stations in South Africa using random regression models. Weekly body weights of Bonsmara bulls (N = 2919) tested between 1999 and 2003 were available for the analyses. The model included a fi.. Read More»

Isolation and characterization of microsatellite markers for the White Cloud Mountain minnow (Tanichthys albonubes) in wild and cultured populations
Authors: J. Zhao, D.-Y. Tseng, H.-D. Lin and X.-T. Lin
We developed 12 microsatellite loci for the endangered minnow species, Tanichthys albonubes, using PCR-based isolation of microsatellite arrays. These new markers were tested in 26 individuals from a wild population collected from Guangzhou in China and 26 individuals from a cultured strain. The number of alleles ranged from t.. Read More»
