Studies regarding the effect of lactation stage on milk content and lipid fraction composition are mostly conducted on milked animals. The aim of this study was to analyze the changes in the basic milk composition and content of fatty acids in the fat fraction during the rearing of lambs in non-milked sheep. The study was carried out on 22 ewes of Polish lowland sheep of Żelazneńska strain, which reared lambs sold at low weight classes (up to 22 kg). Milk samples were collected at 10th (period 1), 25th (period 2) and 52nd (period 3) day of lactation. There were no differences in the amount of the basic components of milk in the studied periods of lactation beside the fat (P ≤0.05) content. There were also no difference in the content of fatty acid groups in the fat fraction of ewe’s milk examined at 10th, 25th and 52nd day of lactation. Although, in the third period of lactation, the content of saturated fatty acids (SFA) was slightly higher compared to first period. In turn, the content of oleic acid (P ≥0.30) and C18:3 (P ≤0.05) was higher in 10th day of rearing then in 52nd day. A slightly larger share of essential C18 unsaturated fatty acids in ewe’s milk in early lactation may suggest the involvement of adipose tissue in the formation of milk fat.","PeriodicalId":413804,"journal":{"name":"Annals of Warsaw University of Life Sciences- SGGW Animal Science","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134087843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the experiment was to determine the effect of the birth weight of piglets on their rearing results up to 56th day of age, as expressed by growth rate and survival. Observations were made on 277 crossbred piglets from 22 litters of F1 sows (Polish Landrace × Polish Large White) derived from crossbred boars (Duroc × Pietrain), which were kept and fed the same way. Piglets were reared with mothers for 5 weeks and observed for 8 weeks. At 1st, 7th, 21st and 56th day of age, piglets were individually weighed. The body weight on day 1 of age served as a basis for dividing the piglets into groups I, II, III and IV (≤1.2; 1.21–1.39; 1.40–1.59; and ≥1.60 kg body weight, respectively). Coefficients of correlation were estimated between body weight on day 1 of age and at day 7, 21 and 56 of life, and daily gains. In the subsequent rearing periods, daily gains in groups I–IV increased and the differences between the groups showed similar relationships. Differences between groups II and III were small (P >0.05), and those between groups I and IV considerable and highly significant. The coefficients of correlation for piglets from groups I (the lightest at birth) and IV (the heaviest at birth) confirm the relationship between birth weight and body weight at 7th (P ≤0.01), 21st (P ≤0.01) and 56th day of age (P ≤0.05), with a downward tendency for the calculated relationships. Furthermore, in group I piglet birth weight was correlated with daily gains from 1st to 7th day (r = +0.365, P ≤0.01) and from 1st to 56th day of age (r = +0.291, P ≤0.05). With the increasing mean body weight at birth, piglet survival increased and was higher in group IV vs I by 13.64 percentage points. The birth weight ≥1.60 kg ensured the best growth rate and survival of the piglets.","PeriodicalId":413804,"journal":{"name":"Annals of Warsaw University of Life Sciences- SGGW Animal Science","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126739528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the result of conducted studies, there were no differences found between the number of breaths or the number of heartbeats in animals of different temperament types. It was found a higher body temperature in vixens with aggressive temperament compared with the vixens of trustful temperament. The difference was statistically significant (P <0.05). The level of cortisol in the blood serum of aggressive and fearful foxes was higher compared with trustful animals. The observed trend was statistically confirmed (P <0.01). In conclusion it can be said that the study of body temperature and the cortisol level in a blood serum of vixens can be a complementary method to evaluate its suitability as a breeding animals.

Moreover, the presence of major pathogenic bacteria was evaluated. The growth of molds was detected in five products. Enterobacteriaceae strains were identified in 12 examined foods. Escherichia coli was identified in four samples. Half of the analyzed foods showed apparent presence of enterococci. All analyzed samples were free from Staphylococcus, Salmonella and Listeria spp. contamination. During microscopic confirmation of suspicious colonies Bacillus spp. were identified in seven products.

This study was aimed at analyzing the effect of the addition of amorphous diatomaceous earth to feed on growth performance parameters and selected quality traits of meat and femoral bone of broiler chickens. The study was conducted with 60 fast-growing Ross 308 broiler chickens, reared until 42nd day of age and divided into a control group (C) and two experimental groups (D2 and D4) (20 birds each). The diatomaceous earth (diatomite) was administered to the birds’ feed from the groups D2 – 2%, D4 – 4%. Individual body weight, feed intake and mortality of chickens were controlled. On day 42 of rearing, six males were selected from each group for slaughter followed by dissection. Dressing percentage, content of muscles and giblets (gizzard, liver and heart), were calculated, and in samples of breast and leg muscles the chemical and physicochemical properties were analyzed. Resistance of the femoral bone to fractures was determined. The addition of diatomite did not affect the health status of chickens. Significantly higher body weight at 42nd day of rearing was noted in the group C vs D4 (P ≤0.05). Significantly higher (P ≤0.01) content of pectoral muscles and lower (P ≤0.05) fat in the carcass of group D2 vs C were noted. The addition of diatomaceous earth did not affect the chemical composition of the breast muscles. The fat content in leg muscles was significantly reduced (P ≤0.05) and water content was increased (P ≤0.05) in group D2 vs C. Femoral bones of D4 birds were significantly more resistant (P ≤0.05) to breaking than in C. Direct relationship between the amount of diatomite and the strength of the femur was found.

Substances derived from nature have natural cytotoxic properties, melittin, the main component of bee venom is one of them. It has the ability to destroy any lipid bilayer, therefore to be used in a cancer treatment it needs to be targeted. The aim is to create the drug delivery system, which would efficiently deliver the active substance to glioma cells. Carbon nanoparticles are considered to be a good agent in biomedical applications, due to their biocompatibility and small sizes. In this study five types of nanoparticles were used: pristine graphene (GN), nanographene oxide (nGO), graphite (G), nanodiamond (UDD) and hierarchical nanoporous carbons (HNCs) to target the melittin to cancer cells. The visualization of the drug delivery complexes of melittin and nanoparticles was done with transmission electron microscopy, the influence of the complexes on cell morphology and structure was pictured with scanning electron microscope. Moreover, in order to check the viability of the cells treated with melittin and the complexes of melittin and nanoparticles the PrestoBlueTM assay was done, also to specify the way of the cell death the annexin V/PI assay was carried out. The results indicate that various nanoparticles behave differently in a complex with melittin. The UDD, GN and nGO nanoparticles resulted in higher mortality than the melittin itself. Creating and applying such complexes of melittin with nanoparticles in glioma cancer treatment may be a promising solution in the therapy.","PeriodicalId":413804,"journal":{"name":"Annals of Warsaw University of Life Sciences- SGGW Animal Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116670875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
