Global Symposium on Women in Fisheries

All over the world, women contribute in multiple ways to the production, processing, marketing and management of fish and other living aquatic resources. The first ever Global Symposium on Women in Fisheries, held in Kaohsiung, Taiwan on 29 November 2001 generated the present collection of papers on women in fisheries. The reader of this volume will find in it a wealth of information, albeit in a very heterogeneous form, that the authors have had to draw from many different sources. Some are primary research studies whereas most are historical reviews from first hand experience of the authors or derived from other written materials, often contained in reports of fisheries development projects, newspapers and source materials well outside the fish sectors.Women, Participation, Sustainability, Poverty, Fisheries, Development projects, Fishery technology

Effects of divergent selection for hind leg muscle volume on its lipid peroxide and glutathione redox status, and fatty acid composition in growing rabbits

[EN] Pannon White bucks were selected divergently using CT method by the volume of the hind leg muscle. Animals showed the highest and lowest muscle volumes were selected as minus and plus-selected variants. The male progenies of the minus and plus-selected parents were slaughtered as fi rst generation which was selected again by CT method and the male progenies of the parents were slaughtered. Results in the fi rst and second generation suggest that selection, as a genetic effect did not affect the rate of lipid peroxidation, as was measured by malondialdehyde content and glutathione redox status, as was measured by the reduced glutathione content and glutathione peroxidase activity of the hind leg muscle. However, there were some differences in the fatty acid composition. Significant (P<0.05) difference was found in palmitoleic acid content which was higher in the minus as compared to the plus variants in the second generation, in eicosadienoic acid which was higher in the fi rst as compared to the second generation of minus variants, and total monounsaturated fatty acids which was higher in the minus as compared to the plus variants in the second generation. It means that selection for higher hind leg volume would not causes marked in changes in the rabbit meat quality as measured by lipid peroxide and glutathione status as well as fatty acid composition.Mézes, M.; Balogh, K.; Fébel, H.; Matics, Z.; Fricska, M.; Szabó, A.; Szendro, Z.

Effect of ambient temperature on the productive and carcass traits of growing rabbits divergently selected for body fat content.

Rabbits are particularly sensitive to heat stress which can affect productive performance, with rabbit breed/line possibly playing a role on the response to this condition. The study aimed at evaluating the effect of different ambient temperatures on the live performance and carcass traits of growing rabbits divergently selected for total body fat content. The two genetic lines (Lean and Fat) were selected based on the total body fat content estimated by computer tomography during five generations. From birth to slaughter (13 weeks of age), the rabbits were housed in two rooms where the temperature was controlled with air conditioners: in the control room the average ambient temperature was 20 °C and in the high temperature room it was 28 °C. After weaning (35 d), 60 Lean and 60 Fat rabbits/room were housed by two in wire-mesh cages and fed ad libitum with commercial pellets. The BW and feed intake (FI) were measured at 5, 7, 9, 11 and 13 weeks of age to calculate the daily weight gain (DWG) and feed conversion ratio (FCR). Mortality was recorded daily. At the end of the experiment, rabbits were slaughtered and carcass traits were measured. Mortality was independent of temperature and line. The temperature significantly influenced the FI, DWG, BW and the fat deposits: they were lower at higher ambient temperature. The effect of temperature differed according to the rabbits' total body fat content. At control temperature, the FI (165 vs 155 g/day; P < 0.05) and FCR (4.67 vs 4.31; P < 0.05) were higher in Fat rabbits, which also had more perirenal (36.2 vs 23.1 g; P < 0.05) and scapular fat (10.8 vs 7.1 g; P < 0.05). At high temperature, no differences in fat depots (14.5 vs 9.8 g; 5.3 vs 3.5 g) were found between the two lines. It can be concluded that temperature × genetic line interaction had an important role in productive and carcass traits, as the effect of temperature differs between Lean and Fat rabbits

Comparison of productive and carcass traits and economic value of lines selected for different criteria, slaughtered at similar weights

[EN] The aim of the experiment was to compare 3 genetic groups, slaughtered at similar weights, to examine their productive and carcass traits and economic value. Three lines of the Pannon Breeding Programme, selected for different criteria, were examined in the experiment. Pannon Ka (PKa, maternal line) does were inseminated with semen of PKa, Pannon White (PWhite) or Pannon Large (PLarge, terminal line) bucks. The kits (PKa×PKa, PWhite×PKa, PLarge×PKa; n=60 in each genetic group) were weaned at 35 d of age and reared until 88, 83 and 79, respectively, when they reached similar body weights for slaughtering (2.8 kg). The weight gain of PLarge×PKa was the largest (51.0 g/d) and that of PKa×PKa was the smallest (47.2 g/d), while PWhite×PKa (41.8 g/d) was intermediate (P<0.001). Difference was found in feed conversion ratio between weaning and the age of slaughter  PKa×PKa: 3.03 respect to PWhite×PKa: 2.75 and PLarge×PKa: 2.66; , P<0.05). Dressing out percentage and ratio of hind part to reference carcass of PWhite×PKa, PLarge×PKa and PKa×PKa were 62.4 and 37.7, 61.8 and 37.5, 61.3 and 36.8%, respectively (P<0.01). Results show that PLarge×PKa rabbits were able to exceed the average economic indicators compared to other groups. It may be concluded that the production performance of growing rabbits was affected by the adult weight, but the carcass traits were influenced by the computer tomography (CT)-based selection.This paper was supported by the János Bolyai Research Scholarship of the Hungarian Academy of Sciences, and by the GOP-1.1.1-11-2012-0132 project.Szendrő, K.; Szendrő, Z.; Gerencsér, Z.; Radnai, I.; Horn, P.; Matics, Z.

EFFECTS OF DIVERGENT SELECTION FOR HIND LEG MUSCLE VOLUME ON ITS LIPID PEROXIDE AND GLUTATHIONE REDOX STATUS, AND FATTY ACID COMPOSITION IN GROWING RABBITS

ABSTRACT: Pannon White bucks were selected divergently using CT method by the volume of the hind leg muscle. Animals showed the highest and lowest muscle volumes were selected as minus and plus-selected variants. The male progenies of the minus and plus-selected parents were slaughtered as fi rst generation which was selected again by CT method and the male progenies of the parents were slaughtered. Results in the fi rst and second generation suggest that selection, as a genetic effect did not affect the rate of lipid peroxidation, as was measured by malondialdehyde content and glutathione redox status, as was measured by the reduced glutathione content and glutathione peroxidase activity of the hind leg muscle. However, there were some differences in the fatty acid composition. Signifi cant (P&lt;0.05) difference was found in palmitoleic acid content which was higher in the minus as compared to the plus variants in the second generation, in eicosadienoic acid which was higher in the fi rst as compared to the second generation of minus variants, and total monounsaturated fatty acids which was higher in the minus as compared to the plus variants in the second generation. It means that selection for higher hind leg volume would not causes marked in changes in the rabbit meat quality as measured by lipid peroxide and glutathione status as well as fatty acid composition

Abstracts of the “26th Hungarian Conference on Rabbit Production”

About 100 participants attended the 26th Hungarian Conference on Rabbit Production at Kaposvár, organised by Kaposvár University, the Hungarian Branch of the WRSA and the Rabbit Production Board. This is the largest and most popular event for rabbit breeders in Hungary. Twenty papers were presented by senior and young scientists. Topics of the papers covered all fields of rabbit production (production, housing and welfare, reproduction, genetics, nutrition, meat quality).

Rendszer az egészségügyi weboldalak hitelesítésére [An objective scoring system to evaluate the credibility of health related websites]

Introduction and aim: The unreliable quality of online health contents poses a serious challenge to the medical profession. Evaluating websites on the basis of their credibility increases the chance for readers to access professional content of better quality. Hungary still lags behind in taking practical steps to improve the quality and reliability of online patient education. Method: EgeszsegKommando (HealthCommando) is a new Hungarian objective scoring system established to evaluate the credibility of health related websites. It uses four types of indicators: transparency, content, recommendations, references. Results: We evaluated 122 websites with EgeszsegKommando. Out of this, 22.1% qualified as credible. The same assessment using JAMA benchmarks yielded only one credible website (0.8%). The most frequent deficiencies were the absence of reference to source, the omission of the quote that "the website information does not replace the doctor-patient discussion", and the identity of the author. In 45.9% of the cases, however, the content was written by medical professionals with contact information. Conclusion: By applying different types of credibility and quality indicators in a scoring system, EgeszsegKommando can efficiently assess the websites on health-awareness. In cases where the recognized indicators are absent multiple times from a website, it will not pass the credibility test. Thus, EgeszegKommando can act as a filter. At the same time, EgeszsegKommando is also capable of assessing webpages of different sorts systemically, and can recommend a proportionately large amount of reliable Hungarian medical web resources to those interested

Effect of genotype, housing system and hay supplementation on performance and ear lesions of growing rabbits

There is growing demand by consumers for meat produced in alternative systems. Since its growing, it could be important to deal with this issue. The aim of the experiment was to examine the effects of genotype (terminal line or traditional giant breed), housing system (cage or pen) and feeding method (only pelleted diets or pelleted diets plus hay) on production and market share is quite small, but is ear lesions of growing rabbits. The crossbred rabbits (n=336) Pannon Large x Pannon Ka (Large) and Hungarian Giant x Pannon Ka (Hung) were weaned at 5 wk of age. Half were randomly housed in cages (3 rabbits/cage) and the other half in pens (14 rabbits/pen). Two other subgroups were formed, rabbits that received only pelleted commercial diets (Pellet) or pelleted commercial diets plus grass hay (P+Hay), ad libitum. Differences were found in body weight at 12 wk of age and in weight gain and pellet intake between 5 and 12 wk in favour of the Large rabbits (3170 vs 2935 g, P<0.001; 42.3 vs 39.5 g/d, P<0.001; 147 vs 132 g/d, P<0.01, respectively). There were no significant differences in feed conversion ratio or mortality. The caged rabbits achieved better results for body weight at 12 wk and daily weight gain than the rabbits housed in pens (3123 vs 2982 g, P<0.001; 42.5 vs 39.4 g/d, P<0.001): while differences in pellet intake, feed conversion ratio and mortality were not significant. The rabbits that consumed only pelleted diets had higher body weights at 12 wk and weight gains than group P+Hay (3093 vs 3017g, P<0.05; 41.6 vs 40.3 g/d, P<0.05, respectively). Ratios of ear lesions in the Large and Hung rabbits were not significantly different but were affected by housing system (0 and 34 %; P<0.001, in cage and pen, respectively) and feeding method (20.6 and 8.3 %; P<0.003, in the groups Pellet and P+Hay, respectively). It can be concluded that the alternative systems negatively influenced the production; the genotype had the greatest, while the feeding method had the lowest impact. Housing of rabbits in large groups was contrary to animal welfare (more ear lesions), although the hay supplementation reduced the aggressiveness
