The PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian commercial sows and native boars were characterized by PCR-RFLP and the pork quality traits were evaluated. Among the 596 pigs studied, 493 (82.7%) were NN and 103 (17.3%) were Nn. There were no differences between NN and Nn pigs in the following pork qualities: pHu (5.71 ± 0.16 vs 5.70 ± 0.11), intramuscular fat (1.55 ± 0.64% vs 1.65 ± 0.67%), shear force (5552 ± 878 g/1.2 cm vs 5507 ± 826 g/1.2 cm), lightness (44.96 ± 2.05 vs 45.01 ± 1.92), redness (0.64 ± 0.60 vs 0.79 ± 0.55), yellowness (6.62 ± 0.56 vs 6.65 ± 0.48), hue (84.28 ± 5.53 vs 83.41 ± 4.85), or chroma (6.68 ± 0.52 vs 6.73 ± 0.52). However, pork from Nn pigs had a significantly (p &lt; 0.05) lower pH45 (6.41 ± 0.27 vs...

Parasites and diseases of commercially important molluscs in New Zealand
Provedor de dados: 5
Autores: Hine, P.
Bonamia has also caused 40%-60% mortalities in two or three stocks of O. lutaria held on a mussel farm 800 km north east of Foveaux Strait. Mass winter mortalities have been reported among native rock oysters, Saccostrea glomerata , until recently the basis of oyster farming. Similar blisters occur in the shell of the currently farmed Crassostrea gigas and may be associated with ectosymbionts. Mortalities and disease have not been reported in the intensively-farmed green-lipped mussel (Perna canaliculus ) or blue mussel (Mytilus edulis aoteanus ), but digenean sporocyts are common in these species. All these bivalve species may contain the copepod, Pseudomyicola spinosus , in the gut, but pathogenicity has not been demonstrated. Pea-crabs are also common...

A self-regularising DVM–PSE method for the modelling of diffusion in particle methods
Provedor de dados: 5
Autores: Mycek, Paul; Pinon, Gregory; Germain, Gregory; Rivoalen, Elie.
The modelling of diffusive terms in particle methods is a delicate matter and several models have been proposed in the literature. The Diffusion Velocity Method (DVM) consists in rewriting these terms in an advective way, thus defining a so-called diffusion velocity. In addition to the actual velocity, it is used to compute the particles displacement. On the other hand, the well-known and commonly used Particle Strength Exchange method (PSE) uses an approximation of the Laplacian operator in order to model diffusion. This approximation is based on an exchange of particles strength.  Although DVM is particularly well suited to particle methods since it preserves their Lagrangian aspect, its major drawback stems in the fact that it suffers from severe...

Effect of storage on the quality of purified live Pacific and Sydney rock oysters
Provedor de dados: 5
Autores: Bird, P; Arnold, G; Holliday, J; Boronovshy, A.
In December, 1990, the N.S.W. Minister for Agriculture and Rural Affairs removed the Pacific oyster (Crassostrea gigas) from the noxious fish list for the Port Stephens area, permitting it's cultivation. As Port Stephens Pacific oysters are grown intertidally, similar to Sydney rock oysters (Saccostrea commercialis) there was a belief that they may have different storage requirements to overseas Pacific oysters which are cultivated in deep water exclusively. Consequently, the keeping quality of this oyster and it's compliance with N.S.W. bacteriological regulations were examined. Port Stephens Pacific and Sydney rock oysters were purified, then stored at refrigeration and ambient temperatures. Levels of faecal coliforms, standard plate count and Vibrio...

Aquaculture in New Zealand
Provedor de dados: 5
Autores: Hayden, B.
Aquaculture is a relatively new activity in New Zealand. The indigenous rock oyster (Saccostrea glomerata ) was the first target for aquaculture in the 1930's although it was not intensively cultured until the 1960's. The faster growing Pacific oyster (Crassostrea gigas ) appeared in 1969/70 and now comprises virtually all the farmed oysters in New Zealand.

Effects of Agricultural Policy Measures on Gross Transfers to Farmers: Intertemporal and Interregional Evidence from the CAP
Provedor de dados: 31
Autores: Hansen,   Heiko.
This paper analyses the effects of the Common Agricultural Policy (CAP) on gross transfers over time and across regions. Depending on the type of instrumentation to support agriculture, the volatility of gross transfers differs. While assistance arising from market price supports, regarded as independent from the world market levels, fluctuates intertemporally, direct payments are constant. Empirical findings for the CAP show a reduction of the transfer volatility on grain markets. For beef and veal this effect is not significant, because price support is still large in these markets. If agricultural support is biased in favour of specific commodities, territorial heterogeneity leads to an uneven distribution. By applying a regionalised concept of producer...

Autores: Kwiecinski,   Andrzej.
Recently, the OECD prepared a detailed review of Ukraine's agricultural policies and potential that included Producer Support Estimates (PSE) calculations. Canada provided a peer-review of this paper. It provides a preview of the caliber and range of information that can be expected from the proposed consortium reviews.  The Ukraine review included discussions of how Ukrainian agricultural policies have evolved and the nature of agricultural support. It also highlighted macroeconomic conditions in the agroprocessing sector and rural infrastructure. In this way, the review drew out Ukraine's path as they grew from a struggling economy to a potential agricultural competitor.

Samples of Pectoralis major m. were collected, and an RT-PCR analysis of the a-Ryanodine receptor (a RYR) from chicken mRNA hotspot region spanning aminoacid residues 386 to 540, numbered according to the turkey sequence, revealed two classes of transcripts. The sequences of the first class were similar to turkey and human with 97% and 74% of identity, respectively, and included all transcripts with substitutions in the nucleotide sequence. The second class was characterized by the deletion of nucleotides, leading to a premature stop codon and coding for a truncated and nonfunctional protein. These results are to date the first report related to the sequencing of the chicken αRYR hotspot region 1, which will possibility serve as a guide for further studies...

O estudo dos parâmetros genéticos das características de qualidade de carne de aves permite à industria avícola se adequar às exigências da indústria processadora, aumentando sua eficiência, e melhorando a aceitação da carne de frango pelo mercado consumidor. Além disso, por meio do estudo destes parâmetros, valiosas informações sobre a caracterização do fenômeno denominado PSE, que representa a carne pálida, flácida e exsudativa, podem ser obtidas, uma vez que são escassos os estudos a esse respeito em frangos. O conhecimento do comportamento genético e da relação entre os atributos da carne e outras características de interesse em frangos de corte pode favorecer o estabelecimento mais preciso e adequado das estratégias utilizadas nos programas de seleção.
