The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

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 Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

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.

SUMMARYTwenty-four Friesian steers, initially 5 months of age, were involved in a 2 × 2 factorial experiment which spanned grazing and silage feeding periods of 22 weeks' duration. In the first period, cattle were stocked at a uniformly high density, with half of the group being fed 1·25 kg/head per day of supplementary barley. In the second period, the cattle were subdivided into four groups and fed varying levels of barley with silage. Finally all the animals received 3·65 kg/head per day of barley. Replicates of the four treatments were slaughtered at random after 5 to 11 weeks on this treatment. Whilst supplementary cereal feeding significantly increased the live-weight gains of steers at grass by 11%, this live-weight advantage was offset by their slower gains in the final weeks before slaughter. Feeding cereals to grazing cattle had little effect on carcass composition or the proportions of carcass joints, but their beef was considered, by a tasting panel, to be more tender than the meat from the control steers.Increasing the level of barley fed with silage only increased live-weight gains by 2%, and had little effect on carcass or meat quality.
