Short Communication: Phenotypic relationship between organ lesions and carcass performance traits recorded in different abattoirs

Abstract. Title of the paper: The influence of MHS-genotypes on fattening and carcass Performance traits of purebred Piétrain pigs and PI x DL slaughter pigs at testing station For the comparison of fattening and carcass performance traits as well as the meat quality of different MHSgenotypes, one Pietrain group with 434 and another one of 64 PI x DL animals of both sexes were evaluated. The LSQ-means from an animal model showed in tendency a lower fattening Performance of the stresssusceptible genotypes. Significant differences were found for higher fat layers and fat surfaces and for lower meat surfaces and percentage of lean meat in NP- and NN-genotypes as compared to the PP-animals. The differences between the MHS-genotypes of the PI x DL animals were similar to those of the Pietrain animals. Both Statistical models confirmed a better meat quality already in the NP-genotypes. With respect to lower loss rates, reduction of insufficient meat qualities (PSE, DFD) and a still high proportion of lean meat of the NP- and NN- animals, a selection ofthe Pidtrain race for stress-resistance should be suitable.

Abstract. The polymorphism of the porcine leptin gene and its relation with some Performance traits (body weight, average daily gains, lean meat content) were analysed in 131 sows of Polish Landrace. The frequencies of detected genotypes TT, TC and CC were 0.763, 0.222 and 0.015 respectively. The estimated frequencies of alleles were 0.874 for allele T and 0,126 for allele C. Lean meat content and average daily gains in TC pigs were statistically significantly higher then those of TT individuals. No statistically significant differences in body weight were found among sows of the above genotypes.

Abstract. Title of the paper: Linear scoring System of legs as selection tool in swine breeding programmes (short communication) A linear scoring system was used to describe leg traits of two pure breed lines of a swine breeding program. Seven Traits were defined on a scale of −3 to +3. Standard deviations, min- and max-values indicate a high variation of the traits. The estimated heritabilities ränge from h2 = 0.10 to 0.25. The genetic correlations between performance traits (live daily gain, backfat thickness) and exterior traits are antagonistic. Therefore further selection pressure for better Performance traits should take account selection for leg traits.

Present investigation was carried out to estimate the correlation and regression coefficientestimates between some growth performance traits of Harnai sheep. The available data was collected andmaintained at Multipurpose Sheep Research Centre Yetabad, District Loralia, Balochistan, Pakistan. Thedata regarding growth traits including birth weight, yearling weight, weaning weight and fleeces weightwas analysed for the estimation of correlation and regression coefficient. In present study the results forcorrelation and regression coefficient estimates were observed low to positive between some growthperformance traits of Harnai sheep. Due to low results for correlation and regression coefficient, it isconcluded that mass selection is advisable for achieving better performance in growth traits of Harnaisheep.

Homologous Chromosomes

The Primary Spermatocytes represent a stage in spermatogenesis when the first meiotic cell division occurs. They are derived from Spermatogonium or Stem cell through mitotic division. At the zygotene phase of meiotic prophase the Synaptonemal complex appears in these cells in the space between the paired homologous chromosomes. Spermatogenesis and sperm structure in fish have been studied at the electron microscope level in a few species? However, no work has yet been reported on ultrastructure of tilapia, O. niloticus, spermatozoa and spermatogenetic process. In this short communication we are reporting the Ultrastructure of Primary Spermatocytes in tilapia, O. niloticus, and the fine structure of synaptonemal complexes seen in the spermatocyte nuclei.
