Analysis of Reproductive Traits of Giant Broiler Rabbit Lines

The aim of this study was to evaluate chosen reproductive traits of synthetic broiler rabbit line. The numbers of 7 reproductive traits were analysed. The synthetic broiler rabbit lines produced from local broiler population and Belgian Giant White sire rabbit were the object of analysis in our study. Number of total born young, lactation at 21st day, number of weaned (35), mortality and relative mortality, litter weight at birth and litter weight at weaning were analysed in experiment. The experiment was carry out in intensive farm conditions with controlled microclimate in wire cages, fed with balanced granulated mixture. Reproduction was provided by artificial insemination, heating and ovulation were stimulated by exogenous hormones. Kindlings were spontaneous and regulated lactation was applied. Following obtained values of analysed lines are presented in results. The average of total number of born in lines F1, B1, B2, B2.1 were 7,9 ; 9,08; 10,25 and 7,75 respectively. Weaning was carry out at the age of 35 days, and the average numbers of number of weaned young were: 6, 35; 7, 75; 8, 85; 5, 25. The mortality up to weaning reach average numbers 1, 55; 1, 08; 1, 5; 2, 5 pieces and 18, 42; 15, 13; 13,97; 33,72 %. The weights of litter at born reach values 240 -- 955 g. The weight of litter at weaning in each line was 4876, 25; 5940, 75; 7165; 4471, 88 g. Lactation at 21th day reaches average numbers 3257, 25; 6837, 5; 4511, 0; 3707, 5 g

The Influence of Gender on Growth Traits of Broiler Rabbits

The present study deals with the comparison of the impact of gender on selected production parameters of rabbits in conditions of intensive farming. The aim of this work was to study and to process the professional and scientific literature that deals with the growth of broiler rabbits. Another objective was to evaluate the growth parameters of the analyzed broiler rabbits population. Followed by an analytical evaluation of live weight differences between male and female hybrid subjects, and a confrontation of observed results with those published in professional and scientific publications. In particular time periods we compared the values of live weight of both sexes. At the 35 days of age live weight of both sexes were almost balanced, but in the 56th day we observed a slight difference in the values of live weight between the sexes. In the last time period, from the 77th to 105th day, the offspring of both sexes reached higher live weight, while we once again identified just small differences in the values of body weight between the two sexes. Over the whole period, we found a slightly higher live weight of males, but the differences between these values are minimal. This means, there is no statistically significant difference between males and females. In terms of statistical significance, we therefore found that the both sexes are growing equally, thus guiding the sex of newborn offspring, is in principle ineffective

Evaluation of European Red Deer (Cervus elaphus hippelaphus) antlers traits in district of Čadca

The phenotype variability of each species is caused by variability of genotype and living conditions. The high degree of Slovak countryside diversity together with occurrence of two subspecies of red deer (Cervus elaphus) create the condition for differences of red deer stags antlers morphometric traits. The aim of this study was to evaluate morphometric traits of red deer stags antlers from north-west part of Slovakia, district of Čadca. Altogether 242 red deer stags antlers were measured. The antlers were measured according to CIC trophy evaluation methods. The stags were hunted in period 2010 to 2017 and the age of measured stags varied from 2 to 14 years. Our study was directly focused to the main trophy parameters that present beam length, number of tines, weight and total points score. The beam length varies from 53.18 to 99.5 cm in 2 y. o. and 14 y. o. stags respectively. The average number of tines increased with the age as well and varies from 6.05 to 15. The average weight of dry antlers (after skull weight deduction) increased according to age of stags from 0.94 kg to 7.54 kg in 2 y. o. and 14 y. o. respectively. The total points score is the indicator of total trophy quality of the population. The values of ]that trait varied from 89.98 points in 2 y. o. stags to 210.20 points in 14 y. o. stags. Significant differences in all traits were determined in confidence level 95 % in relationship to the age of individuals. Red deer as a long-lived animal show a high variability in trophy morphometry related to the age. The highest increasing of all traits is marked especially up to the 7th year of stags in analysed population. This study presents the description and new information of the most important antlers traits from analysed region

Influence of live weight at born on growth traits of synthetic broiler rabbit line

The initial live weight of the body is considered a very important factor influencing the growth traits and the final body weight. The differences are expressive especially in species of large litters and short period of fattening. The large litters are the precondition of different live weights of the youngs. Especially the large litters with more than ten alive youngs produces youngs of different live weight. The aim of this study was to evaluate the influence of live weight at born on growth traits of synthetic broiler rabbit line. The 3rd generation of giant sire line with the basis of Belgian Giant White rabbit and local standard broiler population (M91) was tested in this experiment. Animals born in 18 litters were individually marked and weighted at birth day, 35th day, 84th day and at the age of 105 days. All animals were consequently divided in eight groups according to the live weight at born. The average growth rate of each groups was evaluated. The lowest average live weight at weaning (35th day) was 846.25 g in group 1 and the highest live weight was 1093.18 in group 8 with significant differences between groups (P-value = 0,0000 at the 95,0 % confidence level). Similar results were determined also at the age of 84 days, when the lowest weight was obtained in group 2 and the highest weight in group 8 with average weight 2442,50 g; 3173,64 g resp. Significant differences with P-value = 0,0000 at the 95,0 % confidence level. The 105th day is considered as the age of sexual maturity. The lowest body weight reached group 3 and the highest live body weight was in group 8 with average value 2913.50 g and 3701.82 g resp. The significant differences were determined as well with P-value = 0.0000 at the 95.0 % confidence level

The influence of age on the basic nutritive traits of wild boar (Sus scrofa) venison

The aim of our study was to determine the effect of age on protein, fat and water content in venison of wild boar (Sus scrofa). The sampling took place immediately after hunting, during the primal treatment of the wild boars. The musculus semimembranosus was sampled for the analyses. Monitoring of wild boar was realized in November and December 2016 in hunting region JXXVIII Tribeč (Western Slovakia, mountain range of Tribeč). Analysis of basic nutritive components of venison were determined with FoodScan LAB Analyzer (FOSS, Denmark) – NIR technology. The highest obtained average value of fat content was detected in piglets 4.45%, the lowest average value was in one year old individuals, 2.85%. There was no statistically significant difference in fat content (P˃0.05).The highest average value of protein content was found out in two years old animals and presents 23.31%. The lowest value was determined in group of piglets that reached 22.08%. A statistically significant difference was determined in protein content values (P<0.05). The lowest average value of water content was found out in the group of three years old individuals (69.87%) and the highest content, 72.47% in one year old group in the water content. There was no statistically significant difference (P˃0.05) in water content of venison. However, the age is still considered as a factor influencing the meat quality also from the point of view of human nutrition both of chemical traits
