The MYF5 gene is first inducibly expressed in muscle cell during embryonic muscle development and plays an important role in regulating the differentiation of skeletal muscle precursors. In this study we used PCR-RFLP to investigate two pig (Sus scrofa) populations (n = 302) for two MYF5 gene polymorphisms, a previously unreported novel Met-Leu shift single nucleotide polymorphism (SNP) MYF5/Hsp92II located on exon 1 and the previously identified intron 1 MYF5/HinfI SNP. Haplotype and association analysis showed that haplotypes of the two SNPs were significantly associated with drip loss rate (DLR, p &lt; 0.05), water holding capacity (WHC, p &lt; 0.05), biceps femoris meat color value (MCV2, p &lt; 0.05), biceps femoris marbling score (MM2, p &lt; 0.01),...

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...

The activity of the calpains/calpastatin proteolytic system is closely related to the postmortem tenderization of meat. We investigated the association between beef tenderness and single nucleotide polymorphism (SNP) markers on the CAPN1 gene (SNP316, alleles C/G; SNP530 alleles A/G) and the CAST gene 3' untranslated region (SNP2870, alleles A/G). We sampled nine slaughter groups comprising 313 steers which had been reared in beef production systems in Argentina between 2002 and 2004 from crosses between Angus, Hereford and Limousin cattle. Minor allele frequencies for the markers were 0.27 to 0.46 (C), 0.02 to 0.18 (A), and 0.24 to 0.53 (A), respectively. The presence of CAPN1 markers had significant effects on meat shear force but no detectable effects...

A comparison of growth and biochemical composition of Mytilus galloprovincialis (Lmk.) and Mytilus edulis (L.) on the West coast of Cotentin, Normandy, France 1999-2000
Provedor de dados: 5
Autores: Kopp, Joel; Cornette, Florence; Simonne, Charlotte.
The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from...

Autores: Graziotti,Guillermo H; Ríos,Clara M; Rodríguez Menéndez,José M; Salinas,Matías A; Bosco,Alexis; Paltenghi Ceschel,Alejandra; Affricano,Néstor O; Victorica,Carlos L.
Neuromuscular compartments are subvolumens supplied by a primary nerve branch with homogeneous fiber characteristics. This muscular organization is important for understanding the muscle function in relation to postural and dynamic implications and also is relevant for appraising meat quality. Current researches associate fiber muscle characteristics with perimortem processes that regulate muscle transformation into meat. It is known that pig muscle has four heavy chain myosin isoforms: I, IIa, IIx and IIb. Castrated male pigs were slaughtered at 100 kg live weight. Semitendinosus muscle samples of each subvolumen determined previously (R1, R2, R3, R4) were frozen in liquid nitrogen and reacted for myofibrillar ATPase and NADH-TR for determining fiber...

Autores: Portella,Carolina de Gasperi; Sant'Ana,Léa Silvia; Valenti,Wagner Cotroni.
The objective of this work was to evaluate the chemical composition and fatty acid contents of Amazonian and giant river prawns. After four-month farming, with the same diet for both species, palmitic and stearic acids were the main saturated fatty acids. Oleic acid was the main monounsatured fatty acid, and the eicosapentaenoic and docosahexaenoic acids were the most abundant polyunsaturated acids. Amazonian prawn has higher levels of protein and polyunsaturated fatty acids than those of the giant river prawn, which shows its potential for aquaculture.

BRIDGING THE GAP BETWEEN FARMERS AND CONSUMERS: VALUE CREATION AND MEDIATION IN “PASTURE-RAISED BEEF” FOOD NETWORKS
Provedor de dados: 31
Autores: Bedoin, Florence; Kristensen, Troels; Noe, Egon.
The aim of this article is to explore how different quality dimensions (safety, aesthetics, ethics and rooted ness) are created in food networks; how these qualities are transferred until the consumers; and how this process is supported by the organisation of the food network. Our postulate is that combining the quality and organisation dimensions and exploring the link between them will provide an interesting perspective for improving the sharing of values in food networks. This framework is applied to five case studies of “pasture-raised beef” food networks in France, representing a diversity of organisations such as public label scheme, cooperate owned brand and direct sell from farmer to consumer. The results highlight the importance of the role of...

Estimation of a Multi-Input Multi-Output Model of Lot-Fed Beef Cattle in Australia
Provedor de dados: 31
Autores: Fleming,   Pauline; Fleming,   Euan M.; Griffith,   Garry R.; Johnston,   David.
Most analyses of technical efficiency and productivity focus on the activities of firms or institutions using inputs to produce outputs. In this paper, we report the results of an efficiency analysis that is couched in a different context. We analyse the efficiency with which physical characteristics of individual lot-fed Australian beef cattle are combined with conventional inputs to produce a final product with several attributes that consumers value.  Data on 214 animals across seven breeds were used to estimate a stochastic input distance function with multiple inputs and multiple outputs. Estimates were obtained after controlling for differences between breeds, seasons and sex. Because of variations in feeding regimes for different markets, the data...

Two experiments were conducted to evaluate the effects of dietary oxidized poultry offal fat on the performance of broilers and on the oxidative stability of dark chicken meat. One hundred and sixty male chicks were fed a corn-soybean meal diet containing 4% fresh or oxidized poultry fat from 10 to 47 days of age. Fresh fat was stored frozen until diets were produced, and oxidized fat was obtained by electrical heating (110 to 120 ºC). Birds were slaughtered at 47 days of age, and carcass characteristics were measured. Skinless and deboned thigh meat was stored chilled during 12 days, and samples were periodically collected to assess their quality and oxidative stability. Dietary oxidized fat did not affect bird performance or carcass characteristics....

Autores: Balog,A; Almeida Paz,ICL.
This article aimed at compiling recent studies on the main factors that influence ostrich meat quality and carcass yield. Few articles investigated the effect of subspecies, which generally are not even mentioned. There are important dietary effects, particularly those caused by dietary protein to energy ratio. Rigor mortis follow-up studies showed that there are no losses in meat quality when carcasses are hot-deboned. Age at slaughter influences some meat quality traits, such as tenderness and lipid content. Few effects of gender have been observed, and at the same age at slaughter, both male and female present the same meat quality traits.

ABSTRACT This study aimed to determine the length-weight relationship and mathematical models to predict dressed and fillet weight and yield and fillet composition of wild traíra, Hoplias malabaricus (Bloch, 1794). A total of 80 marketable-sized fish from 292.28 to 2879.57 g and 32.06 to 61.19 cm were used. The length:weight ratio was estimated using the equation:    W = a ×  L b, in which W is body weight (g) and L is length (cm). The models of dressed and fillet weight and yield and body were elaborated using first-order    (   y ^ i = β 0 + β 1  x i ) or second-order    (   y ^ i = β 0 + β 1  x i + β 1  x i 2 ) linear regression analyses. The value of slope b in the length:weight ratio was 3.3732 and intercept was 0.0029. The prediction equations...

Nutritional innovations on amino acids supplementation in Nile tilapia diets
Provedor de dados: 96
Autores: Furuya,Wilson Massamitu; Furuya,Valéria Rossetto Barriviera.
The optimal dietary supply of amino acids to tilapia has been studied for many years. Nevertheless, a general agreement on the amino acid requirement for tilapias has not been established. In order to optimize efficiency and reduce surplus nitrogen, values of digestibility of each amino acid of feed must be considered. Due to variations in the amino acid requirement due to new tilapia strains introduction, continuous research on amino acid requirements is necessary to elaborate economical and environmental sustainability diets, also improving fish growth, efficiency and fillet yield. The concept of ideal protein in tilapia diets was introduced more than ten years ago, and new researches have shown the importance of protein and amino acids on fish...

What mineral and vitamin levels to recommend in swine diets?
Provedor de dados: 96
Autores: Gaudré,Didier; Quiniou,Nathalie.
Minerals, including trace-elements, and vitamins are currently introduced into the pig diet in order to obtain suitable performances for the modern pig genotype bred in confinement. Most of the mineral and vitamin contents of cereals and usual protein compounds are characterized by their poor and variable availability. Supplemental diets are then usually needed. This paper, based on literature data, reviews the pig requirement for minerals and vitamins in order to ensure economic and profitable performance. Recent research has focused on phosphorus due to environmental considerations. The widespread use of microbial phytase has decreased the need for inorganic phosphates. Cereals are particularly deficient in calcium and sodium, consequently limestone and...

New alternatives for improving and assessing the color of dark–cutting beef – a review
Provedor de dados: 63
Autores: Ribeiro,Caio César de Sousa; Contreras-Castillo,Carmen Josefina; Santos-Donado,Priscila Robertina dos; Venturini,Anna Cecilia.
ABSTRACT Myoglobin (Mb) is a sarcoplasmic heme protein present in muscle cells, which acts as a short–term oxygen (O2) reserve in the muscle tissue. After slaughtering and exsanguination, Mb is the major pigment that provides the red color in meat. The concentration of Mb together with its redox state are two pivotal factors that determine meat color. The elevated pH of dark–cutting beef can affect both physical and biochemical properties resulting in decreased oxygenation. The darkening observed in high ultimate pH (pHu) beef concerns meat processors as color is the initial attribute that impacts on the purchase. Thus, any atypical meat color (i.e., loss of brightness) reduces consumer interest in the product. Several studies have demonstrated that...

The aim of the present study was to produce fish silage by lactic acid fermentation and evaluate its use in feeding of quails (Coturnix coturnix japonica). An oven-dried mixture of fish silage and soybean meal (1:1 w/w) was used to prepare the diets with different levels of inclusion (0, 10, 20 and 30%) and evaluate its effect on the performance and meat quality of 160 quails. The inclusion level did not affect the growth and feed conversion ratio. The carcass yield (70.3%) and sensory quality of breast meat were not significantly different among the treatments (p&amp;gt;0.05). However, the concentration of unsaturated fatty acids such as oleic (C18:1n9C), linoleic (C18:2n6C), linolenic (C18:3n3), arachidonic (C20:4n6), cis eicosapentaenoic (C20:5n3) and...

Improving meat quality through natural antioxidants
Provedor de dados: 117
Autores: Velasco,Valeria; Williams,Pamela.
Nowadays, consumers are demanding more natural foods, obliging the industry to include natural antioxidants in foods. Natural antioxidants have been used instead of synthetic antioxidants to retard lipid oxidation in foods to improve their quality and nutritional value. This review discusses some aspects of recent research on antioxidant activity of plant extracts and natural compounds to improve meat quality. Many herbs, spices, and their extracts have been reported as having high antioxidant capacity, such as some plants of the Lamiaceae family, e.g., oregano (Origanum vulgare L.), rosemary (Rosmarinus officinalis L.), and sage (Salvia officinalis L.). The antioxidant activity of these plants is attributed to their phenolic compound content, which...

ABSTRACT: The main application of genomic selection (GS) is the early identification of genetically superior animals for traits difficult-to-measure or lately evaluated, such as meat pH (measured after slaughter). Because the number of markers in GS is generally larger than the number of genotyped animals and these markers are highly correlated owing to linkage disequilibrium, statistical methods based on dimensionality reduction have been proposed. Among them, the partial least squares (PLS) technique stands out, because of its simplicity and high predictive accuracy. However, choosing the optimal number of components remains a relevant issue for PLS applications. Thus, we applied PLS (and principal component and traditional multiple regression)...
