Two groups of turkeys: slow-growing primitive turkeys (SS n = 80 and n = 80) and fast-growing Big-6 turkeys (<$<$ n = 80 and n = 80) were reared in a semi-intensive system: turkey hens until 14th week whereas turkey toms until 22nd week of life. Twelve males and twelve females with body weight corresponding to the mean body weight in a group were selected from each group for slaughter and slaughter...
The aim of this study was to determine the amount of water intake of the chinchilla in a day and to check whether addition of herbal formula with an intense aroma and sweet taste to the water will affect the amount of water intake. Based on our experience it can be concluded that there are large differences in daily water intake between individuals in the sample and individual differentiation is the...
The main problem addressed in this study was to determine the influence of prebiotic preparations DSM Nutritional Products (Biofit Booster and Alphamune) containing hemicelluloses in the form of extracts from the cell wall of Saccharomyces cerevisiae yeast and butyric acid (preparation Adimix) on the quantitative and qualitative status of intestinal microflora of broiler chickens. The study demonstrated...
The study compares honey production in bee colonies with instrumentally inseminated and naturally mated queens. Poland has a special place in the world in terms of the numbers of instrumentally inseminated queens. Our country uses more of them than all other countries taken together. The dense distribution pattern of apiaries in Poland prevents any control over natural mating, while at the same time...
The analysis of results of mares at field performance tests was carried out. The research material consisted of 651 mares, which underwent the field performance test (FPT) in 2002-2011. The effect of the breed on the results in evaluation of free jumping, movement in walk, trot and canter, rideability and on the total score of the test was investigated. The effect of matings on the total score of...
An analysis of results achieved by mares at stationary performance test was carried out. The research material included 901 halfbred mares entered for the Stationary Performance Test in 2007-2011. The effect of the mare's breed on the evaluation scores in free jumping, movement evaluation in walk, trot and canter, rideability, training aptitude and the total score, which was the ultimate evaluation...
Caveolin--1 is a multifunctional protein and major component of caveolae membranes that participates in regulation of signaling pathways, endocytosis and molecular transport. Caveolin-1 takes part in regulation of angiogenesis regulation signaling pathways. Diamond nanoparticle have been shown to inhibit development of blood vessel. Molecular mechanism of diamond nanoparticles anti-angio-genic activity...
The main aim of the study was to compare rearing effect of calves kept outdoor in individual hutches and indoor in group pens. During the experiments following measurements were taken: body weight, daily and monthly gains and mortality. Study was conducted on 90 calves from 5th to 90th days of age and measures were taken in 3 seasons - spring, summer - autumn and winter. All calves were fed with the...
The effect of beef from different fattening systems and of meat of marine fi shes, as being employed and the sole protein and fat source in rats' diets on the selected parameters of their growth and health state was examined. The rats of the experimental groups received meat-free diet (group I - control); groups II-IV - diets with 20% of meat: in group II - meat of marine fishes, in group III - beef...
The aim of the study was determination of number and species composition of entomopathogenic fungi for two river catchments: Zwolenka and Zagozdzonka. Both are left side tributaries of the Vistula River and have different geological structure. The area is dominated by mosaic of extensive agriculture and forests. Three species of entomopathogenic fungi were found: Beauveria bassiana, Metarhizium anisopliae,...
The aim of the study was the comparison of fatty acid composition in longissimus dorsi muscle of ram lambs fattening under overhead shelter versus those in a barn. The maintenance did not influence on main fatty acid composition of muscle tissue. The muscle tissue of lambs reared under overhead shelter compared to these kept in the barn was characterized by significantly higher C10:0, C12:0 (P <...
The study was conducted on 640 chickens randomly divided into two groups, each having four replications (4 control and 4 experimental - L-carnitine) with 80 chickens per pen. Chickens in the control (C) and experimental groups (E) received a feed of the same nutritional value, and chickens from the experimental group were supplemented with Aminocarnifarm (43.68% of L-carnitine) in drinking water (62...
The purpose of this study was to examine the influence phase of lactation on the concentration of saturated fatty acid in milk of high performance dairy cows. The experiment was conducted on the twenty PHF cows at experimental dairy farm of the Warsaw University of Life Sciences. The cows were kept in a free-stall dairy shed and fed on TMR (total mixed ration) diet. The cows had continuous access...
The aim of this study was the quantitive determination of cis-9, trans-11 isomer by two methods: gas chromatography (GC) and silver-ion high performance liquid chromatography (Ag+HPLC) in ewes milk fat. The study was carried out on 20 ewes of Wrzosówka and Żelazneńska sheep, which were mantained at the same environmental and nutritional conditions. The milk samples have been collected from ewes at...
Alpacas are known worldly for their very fine, luxurious fiber which is three times more hardy and six times more thermal than sheep fiber. Aside from fiber, alpacas are also bred for meat and used in the tourism and recreational industry and animal assisted therapy. Possibility of comprehensive use of these animals caused alpacas' popularity to grow immensely over the past few decades all over the...
Increase of genetic potential of fast growing chicken broilers to enlarge size of muscles may lead to decrease quality of the meat because of non-adequate amount of nutrient and energy, stored within the eggs, for providing optimal development. Deliver to the chicken embryo additional amount of energy as ATP or ATP attached to the nanoparticles of silver, as a transporting molecule, may promote growth...
The aim of the research was to analyse the basic body measurements and to define the relationship between pelvis area index (IPM) and body weight (M), height at sacrum (WK) as well as chest circumference (OKP) of Limousine beef cows. Data concerning 634 Limousine cows were taken as a material for investigation. The measurements of chest circumference, height at sacrum and cows body weight were carried...
The experiment was carried out with 320 chickens (fast-growing Hubbard Flex and slow-growing Hubbard JA 957) divided into two experimental groups, each having 160 birds in four replicates, with 40 birds per replicate. During the experiment, body weight was measured initially and at weekly intervals, and feed intake and flock health were determined to calculate feed conversion (kg per 1 kg gain) and...
Fertility of high producing dairy cows is today a big issue for commercial farm in Europe and all around the world. This study was made on Polish Holstein Friesian cows of Agricultural Experimental Farm Wilanôw-Obory (Poland) to evaluate the improvement of fertility permitted by the use of a specific supplementation (Ovulitral) given to the cows just before insemination. This specific dietary supplement...
The aim of this study was to evaluate the reproduction results of mink females, selected for the number of kits weaned in their first reproductive season. The analysis of the reproductive efficiency in two following years indicates that such criterion of mink females selection was apparently ineffective. Slightly increased litter size in the second year was followed by significant decrease in the...
