The study was conducted in 2014 in flock located in West Pomerania Province, on 378 ewes and 96 rams of Polish Merino and 416 ewes and 58 rams old-type Polish Merino. All animals were subjected to the identification of the PRNP genepolymorphism. Based on the studies, there were no effects of breed and sex within breed on frequency of scrapie alleles and genotypes. In Polish Merino were found 5 alleles...
Carcass characteristics and meat quality of extensive grazed Polish Heath Sheep. Slaughter value and fatty acid profile from group of rams and castrates, that were kept on fallow lands used for past 15 years only for sheep production were analyzed. Positive impact of extensive grazing on animals production results during grazing season have been shown. Slaughter analysis have shown beneficial effects...
Effect of the brown coat-coding gene (TYRP-1) on wool and skin color of Żelaźnieńska and Wrzosówka sheep. The study was conducted on randomly chosen ewes (Żelaźnieńska sheep – 93; Wrzosówka sheep - 133) during the shearing. Color of wool and skin was examined using device Chroma Mater CR-400 (Konica Minolta Sensing Inc., 2011). Taking into account the results of genotyping in order to the brown coat-coding...
The study was conducted on Polish Merino (143 ♀ and 39 ♂ ) and old-type Polish Merino sheep (176♀ and 61♂ ) in Brylewo flock (Wielkopolskie Province). The examined sheep were at the age of one year. Prion protein (PrP) genotype was determined in all animals. In both breeds four alleles (ARR, ARQ, AHQ, VRQ) were found. Highly significant effect of breed and insignificant impact of gender within breed...
Polymorphism of insulin like growth factor IGF-1gene in selected Polish sheep breeds. Research was carried out in 2009-2013 on 1751 sheep bred in Poland (1366 ♀; 385♂) - 4 meat-wool breeds: Polish Merino, Old type Polish Merino, Corriedale and Żelaźnieńska sheep and 3 meat breeds (Berrichone du cher, Suffolk, Charolaise) from 34 flocks selected randomly across the country. All animals were subjected...
The study was conducted on 19 samples of wool of Żelaźnieńska Sheep and 28 samples of wool of Corriedale Sheep. The thickness of fi bre and rendement were examined. The color of wool were measured by colorimetric technique. Basis of studies found a wider range of thicknes fi bre of Corridale Sheep and narrow range of thickness fi bre of Żelaźnieńska Sheep compared with the standards. Particular importance...
Research was carried out on 432 Polish Lowland Sheep (405 ♀ and 27♂) of three varieties: Corriedale, Żelaźnieńska Sheep and Polish Lowland Sheep of Podlasie region. All animals were subjected to gene identifi cation factor insulin – IGF-1, in the assessment of alleles C and T. In conclusion it should be noted that in the three examined varieties of Polish Lowland Sheep showed no polymorphism in exon...
The research was conducted on 106 Polish Merino lambs in 2010–2013 and 221 Berrichon du Cher lambs in 2008–2013 (except 2009). The research took place in GRH Żydowo near Gniezno. Animal muscularity was tested by USG technique on mld muscle cross section. Based on obtained results, the effect of type of birth, sex, father origin and class of scrapie resistance and double-factor interactions were statistically...
Research was carried out on 1,684 sheep (1,093 F and 591 M) originating from European Mouflon (Ovis aries musimon), its hybrids with Polish heat sheep and four sheep breeds that are characterized by a mixed wool compared to Polish Merino. All animals were subjected to gene identification factor insulin-IGF-1, in the assessment of allele C and T. In conclusion it should be noted that in the 7 examined...
The polymorphism of prion protein (PrP) amino acids in codons 136 (A/V), 154 (R/H); and 171 (Q/R/H) was established. Reproductive performance of mother sheep was evaluated analysing the fertility coefficient and litter size, i.e. the number of born and reared lambs. The studies included mothers of synthetic lines BCP - 111 sheep and SCP - 104 sheep born in 2001-2007. In the examined ovine PRNP gene,...
The aim of this study was to investigate if use of phytogenic feed additive based of bioactive herbal compounds affected coccidian invasions and production parameters in goats. This research was carried out on a flock of adult Boer goats and their offspring owned by the WULS-SGGW’s Sheep and Goat Research Farm in Żelazna. The experimental and control groups were established regarding 14 and 10 does...
The aim of the study was to establish the frequencies of SNPs polymorphisms in β-lactoglobulin (LGB), κ-casein (CSN3) and growth hormone receptor (GHR) genes in five goat breeds kept in Poland. Blood samples from 24 farms possessing 27 goat flocks of the Alpine (A), Polish Fawn Improved (PFI), Saanen (S), Polish White Improved (PWI) and Boer (B) goat breeds were collected and used for genomic DNA...
Influence of age and sex on body conformation of alpacas bred in Poland. In present work the attempt preliminary characteristic of alpaca build from the national farm on basis selected zoometrics measurements was undertaken. On each of 49 animals the following measurements were taken: height, body length, spread and depth of chest, chest round, spread and length of head, length and round of foreshank...
Effect of rams of meat sheep breeds used in crossing schemes with Polish Merino ewes on slaughter value and meat quality of lambs. The research was carried out in 2008 on the sheep flock in Zydowo (APA). The experimental material consisted of 49 ram-lambs of three genotype groups: the Polish Merino (MP) and its F1 crosses with rams of Charolaise and Berrichon du Cher. The lambs were maintained in...
Effect of sex on slaughter value of lambs of Berrichon du Cher bred in Poland. The research was carried out on male and female lambs of Berrichon du Cher sheep breed. The animals were fed due to the norms. When the lambs achieved the slaughter weight of 35 kg (±1.5 kg), the body measurements at live animals were collected and then the slaughter characteristics on slaughtered lambs were investigated:...
Level of reproduction performance and body conformation of Berrichon du Cher sheep bred in Poland. The research was conducted on 600 ewes and 658 lambs of Berrichon du Cher. The aim of this research was to establish the effect of chosen factors and interactions on the reproduction level in ewes as well as on the body weight at 56 day of lambs' age and the muscularity examined by the USG method. Basing...
Estimated share of veil part in Huacaya alpaca fleece. Research concerned/took up a group of 25 alpacas of Huacaya race, coming from different herds, imported from Chile. The shearing took place in 2009. The fleece was weighed and classified by categories of body parts accordingly. The average estimated weigh of fleece was 1.78 kg and the veil made up 0.650 kg. Influence of gender, age, colour on...
