The researches were carried out on ecotypes of the most ubiquitous sheep breeds in Romania, Tsigai and Tsurcana whose biotopes are circumscribed by more relief forms: plain, hilly, sub-mountainous and mountainous. The sheep were electrophoretically typified at the determinant loci of haemoglobin and transferrin. Using the allelic frequencies of the haemoglobin and transferrin systems that have been processed by concepts of informational statistics, the differentiation / similarity degree among ecotypes within the two breeds was quantified by the genetic distance (D) and the informational correlation coefficient (Rx,y), as well as the diversity level (d) of the genetic structures of these ecotypes on the basis of informational energy (e). Also, the heterozygosity degree (Ht) at the Hb and Tf loci was calculated in relation to the genetic diversity level. The paper analyzes the causes of genetic similarities and differentiations among the ecotypes of these two breeds at the level of the two biochemicalgenetic loci: allelic distribution of haemoglobin and transferrin, altitude of relief forms, habitat conditions etc. The benefits of such studies are also presented for the improvement, breeding and conservation of the ecotypes of these two sheep breeds from Romania.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The goal of this study was to determine the effects of prebiotic products (Actigen AŸi Biotronic Top3) on meat quality in broiler chickens. The research has been conducted on a number of 75 Ross-308 hybrid broilers, assigned in three groups (25 individuals/group), over a period of 42 days. Group 1(E) was fed with the base diet supplemented with the Actigen prebiotic in a proportion of 0.08% in the first growth phase (days 1-14), 0.04% in the second phase (days 14-35) and 0.02% in the third phase (days 35-42). Group 2(E) received the base feed supplemented with the Biotronic Top3 prebiotic (0.1%) throughout the whole growth period. At the end of the study period, five broilers from every group have been sacrificed to determine meat quality and meat chemical composition. The usage of prebiotics led to an increase of the carcass weight gain of 16.29% in group 1(E) receiving Actigen and 13.49% in group 2(E), fed with Biotronic Top3, compared to the control group. The percentage of superior quality meat (quality I and II) in the carcass was higher by 4.4% in group 2(E) Biotronic Top3 and by 1.67% in group 1(E) Actigen compared to the control group. Following the administration of Actigen and Biotronic Top3 prebiotics, in groups 1(E) and 2(E) the meat quality was improved in groups 1(E) and 2(E), due to an increase in the protein content and a reduction of the fat content. These results confirm that prebiotics administered in the feeds for broiler chickens have favourable effects on the meat production and meat quality.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Even though classical scrapie has been known for over 250 years, the 1985 BSE crisis related to the advent of new forms of the Creutzfeldt-Jakob disease (vCJD) in humans imposed the implementation of rapid coercive legal measures of prevention, control and eradication of TSEs. According to the prion hypothesis, the transmissible agent is the pathological isoform (PrP Sc ) of cellular prion protein (PrP C ). Specific polymorphisms of the gene that encodes cell prion protein (PrnP) in sheep have been associated with resistance / natural susceptibility to the development and progression of the disease. Combinations of alleles at three adjacent codons (136 [A/V], 154 [H/R], 171 [H/Q/R]) underpin the classification of 15 possible genotypes in risk classes, applicable in selection schemes where the maximum resistance is conferred by ARR allele, and the minimum by the VRQ allele. Although, after applying these programmes, the genetic structure of sheep populations has changed favourably, genotype association studies showed that no genotype is completely resistant to the infection, including homozygote ARR / ARR. With the discovery of atypical scrapie (Nor98), it became evident that the connection between the genetics of prion protein gene polymorphisms and susceptibility to the disease must be re-evaluated individually for each breed. In scrapie monitoring and control programmes, three diagnostic categories of the disease are observed: classical scrapie, atypical scrapie and BSE scrapie in small ruminant. This review shows the chronology of progress in the fight for the eradication of TSEs in sheep, 30 years after the BSE epidemic outburst, focusing especially on the link between the molecular diagnostic forms and the genetics of the disease.

The composition of animal and human colostrum depends very much on different factors such as: animal species, animal breed and genetical characteristics, feeding program, diet. Bovine colostrum is used in different therapies due to its composition in nutraceuticals, but also because the cow gives high quantity colostrum compared to other animal species (goats or ewes). The immunological properties of colostrum are acknowledged in various studies. Due to its immunoglobiline content, it is an alternative therapy in immunity enhancement. Colostrum is also used in athletesâ€™ supplementation plan with very good results in their competition performance. Dry matter composition of cow, goat and eweâ€™s colostrum can give very good information about the nutritional composition, especially proteins. Thus, proteins, lipids, minerals, vitamins are significantly higher in colostrum right after parturition and decrease very much in time in mature milk. Lactose - in most of the studies - presents an increase in concentration from colostrum to milk.
