Production and composition of milk from tsigai sheep breed in Vojvodina

In this study the milk quality of Tsigai, like a most popular local sheep breed in northern part of Serbia are presented. The purpose of this paper is to review the several differences in physical-chemical quality aspects of sheep milk.. The average milk quantity are between 0,46 and 0,88 kg, and in 6 mounth milking period are up to 150 l. The milk is mostly processed into cheese and yoghurt. Compared results with other Tsigai breeds in Midle-East Europe area indicate that milk yield and composition are approximately the same, depending on pasture quality, keeping system and feeding

Growth performances and hematological characterisation of rainbow trout (Oncorhynchus mykiss Walbaum, 1792)

In present study correlations between hematologic characteristics and growth performances of rainbow trout were investigated. Fish were provided from a raceway trout farm located in the valley of the river Jerka near the city of Novi Pazar (N:43°13’67’’; E:20°43’96’’). The farm consists of 8 concrete lined production ponds (22 x 3 m x 1,2 m each) in which water is exchanged 75 times per day. After stocking fish from production ponds are being monthly classified into two groups depending on their body mass and body length and larger fish are transferred in separate ponds. For this study one year old fish were sampled. 25 from slower and 25 from faster growing group. Analyses were performed in 4 consecutive days in accordance with animal welfare regulations (Official Gazette of the Republic of Serbia 41/2009). Fish growth performances were estimated from body mass, total and standard body length and Fulton condition factor. Hematological characterization of rainbow was established on the basis of Red Blood Cell (RBC) and White Blood Cell (WBC) count, hemoglobin concentration, Packed Cell Volume (PCV), Mean Corpuscular Volume of erythrocytes (MCV), Mean Corpuscular Hemoglobin in individual erythrocyte (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC) in a liter of erythrocytes. The results obtained were statistically analyzed by SPSS. It was found out that there exist significant correlation between hematological and growth characteristics. High linear regression coefficients can explain mass and length gain by hematological parameters

The possibilities of organic farming in Vojvodina

Organic livestock farming needs a balance between ecology and economy. The organic husbandry are a new possibility for livestock production in Vojvodina. Marketing of produced animal originated products became more popular, and it is organized by farmers themselves, or by their associations. Organic livestock farming in Vojvodina – Northern region of Serbia, is at its very beginnings. The present paper describes the actual situation in organic farming, and possibilities of its improvement. The essential systemic unit is the farmstead which presents a base for organic farming. From the environmental point of view there are several factors like surroundings and landscape which determinate the way of farming. In some ways big differences could be observed on the right and left side of the river Tisa. The quality of soil is determinative. In Banat region we could find mostly pastures and meadows which are suitable for grazing. The conventional, extensive animal breeding – sheep and goat milk as well as the lamb production could be preferred. On the right side of the river Tisa, Backa is the intensive agricultural region with good arable land, therefore it is very suitable for indigenous pig breeding, using famous Mangalica pig. If breeders’ demand will appear in near future, a nucleus of Mangalica breed could be established. Biodiversity of poultry breeding depends mostly on the traditional poultry production and the gene conservation programmes. Based on production guidelines, organic livestock farming in Vojvodina has set the goal of establishing environment - friendly production, sustaining animals in good health, realizing high animal welfare standards, and producing high quality products

Evaluation of environmental conditions by fish hematology

In the work are shown basic principles of application of the haematological status in determination of physiological status of fishes, also a review of a number of research from this area is given. One part of the research includes analysis of parametres of hematological status of the individuals in their natural habitat, while the other part is focused on the research of these parametres in experimantal conditions based on changes of some of the factors. Review include erythrocyte line parameters (erythrocyte number, hemoglobin concentration, hematocrit, MCV, MCH and MCHC) in different conditions in species: Barbus balcanicus, Sqalius cephalus, Thymallus thymallus, Oncorhynchus mykiss, Carassius gibelio, Perca fluviatilis, Cyprinus carpio
