This study aimed to examine the quality of broiler carcasses in the Banyuwangi traditional market with carcass quality examination based on SNI number 3924-2009 and tetracycline antibiotic residues test based on SNI number 7424:2008. A total of ten broiler chicken sellers as representative of almost all broiler chicken sellers in the Banyuwangi market, with each seller was taken for one carcass in this research. Carcass quality examination used a standart carcasses weight 1,0-1,3 kg. Carcass quality examination was carried out with descriptive analysis with reference to the physical characteristics of SNI (Standarisasi Nasional Indonesia). The bioassay method is used to test for tetracycline antibiotic residue. The result of the carcass quality examination showed that from the whole sample consisting of conformation, disjointed or broken bones and missing parts, discolorations, and cleanliness of broiler carcasses are good enough. The percentage quality of broiler carcasses quality I is 60%, quality II is 30% and quality III is 10%. The examination of antibiotic tetracycline residues in broiler meat showed negative results indicating that no feeds containing additional antibiotics made carcasses in the traditional Banyuwangi market safe for consumption.

This study was conducted to determine the effect of neem leaf infusion on growth parameters, carcass characteristics and meat quality of broiler chicken. One hundred and sixty, seven days old broiler chicks of cob strain were used for the experiment which was laid out in a completely randomized design (CRD). Each group was sub-divided into four replicates of 10 birds. The chicks in group 1 served as control and antibiotics were administered to them while 0.1, 0.2 and 0.3% concentration of neem leaf infusion were administered to bird on groups 2, 3 and 4, respectively. The period of experiment was six weeks. The birds were fed ad libitum. One bird close to average final weight was selected randomly in each replicate and was slaughtered at 42nd day of the experiment. Meat samples from breast muscle of the bird were subjected to cooking weight loss, refrigeration weight loss and sensory evaluation. The data obtained were subjected to one-way Analysis of Variance. Results revealed that there were no significant (p>0.05) effects of neem leaf infusion on weight gain and feed conversion ratio while water intake was influenced (p<0.05) at the starter phase across the treatment groups. It was only feed intake that was influenced (P<0.05) by the Neem leaf infusion (NLI) at the finisher phase. The heart was the only parameter that was significantly (p<0.05) affected among the carcass parameters. The cooking loss increased (P<0.05) with higher concentration of the infusion while refrigeration weight loss percentages were similar (P>0.05) across the treatments. The result on Sensory evaluation showed that only colour, tenderness and overall flavour were significantly (P<0.05) influenced. The study concluded that administration of aqueous Neem (Azadirachta indica) leaf infusion in drinking water of broiler chicken as alternative to antibiotics did not pose any adverse threat on the performance and meat quality of broiler chicken.     Cette étude a été menée pour déterminer l'effet de l'infusion de feuilles de neem sur les paramètres de croissance, les caractéristiques de la carcasse et la qualité de la viande du Effect of neem (Azadirachta indica) leaves infusion on growth performance and carcass quality of broiler chickens  poulet de gril. Cent soixante poussins de poulet à griller de sept jours de souche d'épi ont été utilisés pour l'expérience qui a été présenté dans une conception complètement randomisée (le 'CRD'). Chaque groupe a été subdivisé en quatre répliques de 10 oiseaux. Les poussins du groupe 1 ont servi de contrôle et des antibiotiques leur ont été administrés tandis que 0,1, 0,2 et 0,3 % de concentration d'infusion de feuilles de neem ont été administrés à l'oiseau sur les groupes 2, 3 et 4, respectivement. La période d'expérience était de six semaines. Les oiseaux ont été nourris ad libitum. Un oiseau dont le poids final est proche de la moyenne a été sélectionné au hasard dans chaque réplique et a été abattu au 42e jour de l'expérience. Des échantillons de viande prélevés sur le muscle mammaire de l'oiseau ont été soumis à la perte de poids de la cuisson, à la perte de poids de réfrigération et à l'évaluation sensorielle. Les données obtenues ont fait l'objet d'une analyse à sens unique de la variance. Les résultats ont révélé qu'il n'y avait pas d'effets significatifs (p>0,05) de l'infusion de feuilles de neem sur le gain de poids et le rapport de conversion des aliments pour animaux, tandis que la prise d'eau a été influencée (p<0,05) à la phase de démarrage dans tous les groupes de traitement. Ce n'est que la prise d'aliments qui a été influencée (P<0,05) par l'infusion de feuilles neem (NLI) à la phase finale. Le cœur était le seul paramètre qui était significativement (p<0,05) affecté parmi les paramètres de la carcasse. La perte de cuisson a augmenté (P<0,05) avec une concentration plus élevée de l'infusion tandis que les pourcentages de perte de poids de réfrigération étaient similaires (P>0,05) à travers les traitements. Le résultat de l'évaluation sensorielle a montré que seules la couleur, la tendresse et la saveur globale étaient significativement influencées (P<0,05). L'étude a conclu que l'administration de feuilles de neem (Azadirachta indica) dans l'eau potable du poulet de gril comme alternatif aux antibiotiques ne posait aucune menace négative sur la performance et la qualité de la viande du poulet de gril.

The aim of this study was to estimate the effect of feeding system on the growth rate and carcass quality of crossbred Improved Jezersko-Solčava x Texel (JSRT) lambs and to evaluate the effect of sex on these traits. The trial was conducted in nature according to the traditional rearing systems. The trial included 44 crossbred lambs, which were born and reared until the slaughter in three different flocks. In the age of 10 days suckled lambs were offered with ad libitum corresponding diets according to the feeding system. All lambs were slaughtered in seven consecutive days by the same procedure. The effect of feeding system significantly affected daily gain from birth to slaughter, EUROP carcass conformation and shoulder width. Likewise, the effect of sex significantly affected daily gain from birth to slaughter and internal fatness of carcasses. According to carcass cuts the feeding system significantly affected only the proportion of neck and leg. Considering meat quality traits, feeding system had a significant effect on the pH 45 and CIE a* values. In this study, we could speculate that more than the feeding system the growth and the carcass traits as well as meat traits were affected by the amount of the supplement.

Abstract Background Transcription is arrested in the late stage oocyte and therefore the maternal transcriptome stored in the oocyte provides nearly all the mRNA required for oocyte maturation, fertilization, and early cleavage of the embryo. The transcriptome of the unfertilized egg, therefore, has potential to provide markers for predictors of egg quality and diagnosing problems with embryo production encountered by fish hatcheries. Although levels of specific transcripts have been shown to associate with measures of egg quality, these differentially expressed genes (DEGs) have not been consistent among studies. The present study compares differences in select transcripts among unfertilized rainbow trout eggs of different quality based on eyeing rate, among 2 year classes of the same line (A1, A2) and a population from a different hatchery (B). The study compared 65 transcripts previously reported to be differentially expressed with egg quality in rainbow trout. Results There were 32 transcripts identified as DEGs among the three groups by regression analysis. Group A1 had the most DEGs, 26; A2 had 15, 14 of which were shared with A1; and B had 12, 7 of which overlapped with A1 or A2. Six transcripts were found in all three groups, dcaf11, impa2, mrpl39_like, senp7, tfip11 and uchl1. Conclusions Our results confirmed maternal transcripts found to be differentially expressed between low- and high-quality eggs in one population of rainbow trout can often be found to overlap with DEGs in other populations. The transcripts differentially expressed with egg quality remain consistent among year classes of the same line. Greater similarity in dysregulated transcripts within year classes of the same line than among lines suggests patterns of transcriptome dysregulation may provide insight into causes of decreased viability within a hatchery population. Although many DEGs were identified, for each of the genes there is considerable variability in transcript abundance among eggs of similar quality and low correlations between transcript abundance and eyeing rate, making it highly improbable to predict the quality of a single batch of eggs based on transcript abundance of just a few genes.
