The research was carried out on 38 Kołuda ewes. Two trial milkings were done in June 2013 – the first in the 9th week of lactation, in the final suckling period, and the second in the 11th week of lactation, 14 days after weaning of lambs was complete. Thirty-eight ewes were chosen and randomly assigned to two groups, each consisting of 6 ewes rearing single lambs, 10 with twins and 3 with triplets. Before the first trial milking (I) the ewes were separated from their lambs for 12 hours. Half of the ewes were milked in the presence of lambs (group A) and the other half in the absence of lambs (group B). Samples of milk from the same ewes were taken during the commercial milking period, 2 weeks after the lambs had been weaned (second trial milking – I). There were no differences in milk yield or milk composition between ewes milked in the presence and absence of lambs. Milk of ewes milked 12h after separation from lambs had lower content of total solids (15.05 vs. 16.48 g/100 g, P≤0.01), protein (4.82 vs. 5.18 g/100 g, P≤0.01) and fat (4.84 vs. 6.05 g/100 g, P≤0.01) but higher content of lactose (5.02 vs. 4.78 g/100 g, P≤0.01) compared to milk from the same ewes 2 weeks after the lambs were weaned. The research showed a tendency in ewes rearing twins milked following separation from lambs to produce more milk, with higher content of total solids and fat but lower lactose content, in comparison to ewes rearing single lambs. Milk of ewes rearing triplet lambs did not differ from that of ewes rearing single and twin lambs, with one exception – milk of ewes rearing triplets had lower lactose content than the milk of ewes with single lambs.

Badania przeprowadzono na 38 matkach owcy kołudzkiej. Dwa próbne doje owiec przeprowadzono w czerwcu 2013 roku – pierwszy w 9. tygodniu laktacji, w końcowym okresie karmienia jagniąt (12 godzin po odseparowaniu jagniąt od matek) oraz drugi w 11. tygodniu laktacji, 14 dni po odsadzeniu jagniąt od matek. Owce przydzielono losowo do dwóch grup, w każdej po 6 matek odchowujących pojedyncze jagnięta i 13 odchowujących bliźnięta i trojaczki. Połowa owiec była dojona bez obecności swojego potomstwa (grupa A), a pozostałe w obecności jagniąt (grupa B). Próby mleka od tych samych owiec pobrano również w okresie doju towarowego, po upływie dwóch tygodni od definitywnego odsadzenia jagniąt. Nie stwierdzono statystycznie potwierdzonych różnic w wydajności mleka i zawartości jego składników między owcami dojonymi w obecności lub bez obecności jagniąt. Mleko owiec dojonych 12 godzin po odseparowaniu jagniąt zawierało mniej suchej masy (15,05 vs. 16,48 g/100 g, P≤0,01), białka (4,82 vs. 5,18 g/100 g, P≤0,01) i tłuszczu (4,84 vs. 6,05 g/100 g, P≤0,01), ale więcej laktozy (5,02 vs. 4,78 g/100 g, P≤0,01) w porównaniu z mlekiem od tych samych owiec udojonym 2 tygodnie po odsadzeniu jagniąt. Matki odchowujące bliźnięta i dojone po odseparowaniu jagniąt miały wyższą wydajność mleka, suchej masy i tłuszczu, a niższą laktozy oraz niższy stosunek białko/tłuszcz w porównaniu z matkami odchowującymi jedynaki. W okresie po odsadzeniu jagniąt, u dojonych owiec odchowujących bliźnięta, w porównaniu z odchowującymi jedynaki, obserwowano tendencje do wyższej produkcji mleka, o wyższej zawartości suchej masy i tłuszczu, przy niższej zawartości laktozy i niższym stosunku białkowo-tłuszczowym. Mleko owiec odchowujących trojaczki nie różniło się od mleka matek odchowujących jedynaki, z wyjątkiem niższej zawartości laktozy.

Perinatal calf mortality affects profitability of beef cattle production systems, hence, it Gould eventually be beneficial to include this trait in a breeding goal. The objectives of this study were to estimate the environmental effects and heritabilities of and genetic correlations among birth weight (BW), calving ease (CE) and calf survival (CS) in Charolais cattle, in the Czech Republic.The dataset contained 27,402 field records. Fixed effects in the 3-trait model were year of birth, age of dam, sex, and litter size of calf. Random effects in the model were direct and maternal genetic effects, maternal permanent environment, contemporary group (herd x year x season), and residual.Birth weight was modelled as a normally distributed trait, while for calf survival a linear logit model was applied. The CE score was either transformed to be normally distributed (T1) or treated as a binary trait (T2). For T1, heritabilities for the direct genetic effect were 0.23, 0.21 and 0.05 for BWd, CEd and CSd, respectively; while heritabilities for maternal genetic effects were 0.10, 0.02 and 0.05 for BWm, CEm, and CSm. Genetic correlations among BW, CE and CS were close to zero for both direct and maternal genetic effects with the exception of that between BWd and CEd (0.21 for T1 and 0.24 for T2). Results suggest that low additive direct and maternal genetic variances for calf survival and low to modest direct and maternal genetic correlations between BW, CE and CS would limit effectiveness of selection for calf survival in a breeding program, in spite of its economic importance in beef cattle production.

The objectives of this study were to evaluate systematic factors that influence longevity and to estimate the heritability of functional longevity by survival analysis of Suffolk sheep in the Czech Republic. A total of 20,502 ewes from 137 flocks were used. The longevity of Suffolk ewes was influenced to some extent by their average prolificacy. The effects of growth intensity and the development of muscularity and fattiness, as well as the effect of the prion protein gene PrP haplotype on the risk of the exclusion of the ewe from breeding were relatively low. Heritability estimates were h² = 0.438 for the length of production life in days (LPL), h² = 0.098 for the number of litters of the ewe during her lifetime (NL), h² = 0.111 for the total number of lambs born (TLB), and h2 = 0.103 for the total number of labs weaned (TLW). Correlations between the breeding values for LPL and NL, TLB or TLW were high. Therefore, these indicators of the ewe’s lifelong production, which are more desirable and understandable for sheep breeders, should be used in indirect selection for longevity.

In the Czech Republic, dairy sheep have traditionally been used as a dual-purpose species, generating income from both milk and meat. The functionality and health of the mammary gland are directly correlated with milk production, as well as with the hygiene and quality of milk and dairy products. Mastitis is one of the main infectious diseases in dairy sheep. One of the candidate genes that affect milk production traits is the ATP-binding cassette sub-family G member 2 (ABCG2) gene. The ABCG2 gene, a member of the ATP-binding cassette family, transports cytostatic and xenobiotic drugs across the cytoplasmic membrane. The study was based on 1747 records from 387 head of dairy sheep of the Lacaune breed (139) and the East Friesian breed (248). The analysis was performed by means of polymerase chain reactions (PCR). Genomic DNA was extracted from blood. Phenotype data used in the study were provided by the Association of Sheep and Goat Breeders in the Czech Republic (ASGB). We typed all three genotypes: DD, DI and II. In the Lacaune breed, the frequency of occurrence of the major D allele was 0.694, and the minor I allele had a frequency of occurrence of 0.306. In contrast, in East Friesian sheep the frequency of allele D was 0.216 and that of allele I was 0.784. Mutation c.683-80_46del in the intron 5 region of the ABCG2 gene confirmed the effect on somatic cell count in the dairy sheep population observed in this study. Further studies are needed to evaluate this possible association in other sheep breed populations. Mutation c.683-80_46del in intron 5 of the ABCG2 gene could be used as a candidate gene for somatic cell count.

Our objective was to compare the effects of a conventional antiparasitic chemical drug and a lick block containing plant-based compounds on the economic value of lambs. Ewes and their new-born offspring were allocated among three treatments: a group receiving standard drenching with an albendazole-containing drug, a group supplied with a lick block containing essential oils from 10 plant species having antiparasitic properties, and a control group that was not dewormed. During the experiment, all lambs were given periodic birth weighings at 28, 56, 70 and 100 days of age. The results obtained were the basis for the estimation of the economic value of lambs reared in particular experimental groups of the observed animals. The average price earned for slaughter material in each weight standard was used to calculate the differences between the groups. The current prices were made available by the Regional Association of Sheep and Goat Breeders in Lublin. All lambs (live at 56, 70, 100 and 120 days) were included in calculations of the average value of the animals. In the case of lambs falling within the standard 0 to 12 kg, a value for 0 PLN per kilogram was assumed because of the lack of sales potential. At 56 days, the value of the lambs in the group receiving feed with the addition of essential oils was 11.90% higher than that of the lambs from control group. At 70, 100 and 120 days, the value of those lambs was higher than that of the lambs from control group by 21.13%, 4.99% and 5.51%, respectively. The value of the lambs from the group receiving standard drenching with an albendazole-containing drug was similar to that of the lambs from the undewormed group. The results of the research indicate that it is beneficial to use natural substances in the prevention of parasitic invasion. The use of natural methods to reduce parasitic infestations will reduce the application of chemicals, which is extremely important due to the increasing resistance of parasites and the preferences of consumers, who search for products free of harmful residues of medicinal substances.

The aim of the study was to evaluate the efficiency of various methods of antiparasitic prophylaxis using a conventional chemical agent and a formulation containing plant essential oils. The animal material consisted of 139 mother ewes of two synthetic prolific meat lines: BCP and SCP. During the entire experiment the animals were kept in an indoor management system with uniform environmental conditions. The experiment included ewes lambing within the period of 12 consecutive days. Using the results of coproscopic tests performed after lambing, the animals were randomised into three study groups: Group A – wormed with an albendazolecontaining preparation (50 sheep); Group L – receiving a lick with antiparasitic essential oils (48 sheep); and Group C – control group, not wormed (41 sheep). Two antiparasitic agents were used. A chemical agent containing albendazole. The procedure was performed on day 35 after lambing, and the dose administered was 5 mg of the active substance per kg bw, which corresponded to 0.5 ml orally, per 10 kg bw. A natural worming agent was administered in the form of licks containing essential oils of Thymus vulgaris, Allium sativum, Artemisia absinthium, Dryopteris filixmax, Tanacetum vulgare, Cucurbita pepo, Chenopodium ambrosioide, Inula helenium, Peumus boldo and Corallina rubens. The licks were made available to animals on day 21 after lambing. The experiment involved parasitologic tests aimed at the determination of estimated intensity (based on OPG and EPG data) and prevalence of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum on the following dates: after lambing, and on day 28, 42, 56, 70 and 100 of a lamb’s life. The observations proved that the formulation based on natural plant ingredients had a beneficial influence on the reduction of prevalence of Eimeria and Capillaria. It was also shown that the albendazole-containing chemical preparation is highly efficient in reducing the prevalence of Trichostrongylidae, Nematodirus, as well as Capillaria.

The aim of the study was to evaluate the influence of preventive activities involving the use of a coccidiostatic product containing Origanum vulgare and Citrus spp. extracts on the slaughter value of lambs from a confined management system. The study material was a group of 222 mother ewes and 276 lambs of the Polish Lowland breed. During the whole experiment the animals were kept in a confined management system, indoors, with uniform environmental conditions. On the basis of the parasitological analysis the flock was divided into three groups similar in both the intensity and the extensity of parasitic infections: Group 1: a control group, whose diet was not supplemented (74 mother ewes, 87 lambs); Group 2: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing the lambs were fed like the control group (73 mother ewes, 105 lambs); Group 3: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing, the lambs receiving feed with OILIS SD starting from the 14th day of life (75 mother ewes, 84 lambs). Out of 276 lambs included in the experiment, 18 rams and 18 ewes representing all the observed groups were chosen for slaughter. The lambs were slaughtered around day 100 of their life (± 6 days). The observations showed that the animals from Group 3, in which the feed of both mother ewes and lambs was supplemented with a coccidiostatic product, were characterized by a higher slaughter weight: 30.80 kg, in comparison to 27.80 kg in Group 1 and 26.90 kg in Group 2, which has been confirmed as statistically significant (p ≤ 0.05). This corresponded to the achieved carcass weight. The highest average hot carcass weight (13.36 kg) was noted in Group 3, while the parameters for Group 1 (11.88 kg) and Group 2 (11.28 kg) were significantly lower (p ≤ 0.05). The conducted post-slaughter analysis clearly showed that the coccidiosis prevention measure consisting in a product containing the ether oils of Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) has a beneficial influence on the slaughter value of lambs, and results both in a higher carcass weight and the weights of specific cuts and tissues.

Invasions of protozoa belonging to the genus Eimeria are a global problem in sheep farming. The clinical course of eimeriosis occurs almost exclusively in lambs. In adult sheep coccydiosis often has an asymptomatic course which, however, is not without an impact on animal conditions. Large flock density and related contamination of the environment with oocysts is conducive to a high extensiveness of the invasion. The aim of the study was to analyze the prevalence and intensity of Eimeria invasion in lambs kept in confined management systems in order to establish the key periods of the course of invasions and schedules for prevention programs. The parasitological examination was conducted on samples of feces collected directly from the rectum of 96 lambs every 14 days at the following time points: the 28th, 42nd, 56th, 70th and 100th days of life. The assessment involved the invasion extensity established using a flotation method and invasion intensity expressed as the number of oocysts per gram of feces (OPG) established by using the McMaster technique. On the basis of morphometric parameters of isolated oocysts, the species of coccidia in the studied animals were determined. During the whole study period, the invasion extensity grew from the minimum of 17.6% (CI ± 95%; 9.6-25.6) on day 28 to the maximum of 95.9% (CI ± 95%; 95.3-100.0) on day 100. The average growth in the invasion extensity in the flock was 19.6% every 14 days. The average invasion intensity in the study period was 3039.2 OPG (min-max 50-58,800; SEM 440.2), with the highest excretion of oocysts observed on day 42 of the lambs’ life. The average OPG value on this day was 6783.8, and dropped at subsequent measurement points. The experiment revealed exclusively multi-species invasions. In total, seven species of coccidia were found in the studied animals within the study period. These were: E. bakuensis, E. faurei, E. intricata, E. ovinoidalis, E. pallida, E. parva and E. crandallis.

The aim of the study was to determine the efficiency of a formulation containing essential oils from Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) in limiting the prevalence and intensity of parasitic invasions in ewes kept in an indoor management system. The study material was a group of 222 mother ewes of Polish Lowland breed. During the entire experiment, the animals were kept in an indoor management system with uniform environmental conditions. On the basis of the parasitologic analysis, the flock was divided into three groups. All groups were uniform from the perspective of genetic traits, age and environmental conditions. The differentiating factor was the addition of a preparation containing essential oils from Origanum vulgare and Citrus spp. in the dose of 4 kg/ton of feed. Group 1 – control group, non-supplemented diet (74 mother ewes); Group 2 – supplemented diet from third month of pregnancy to lambing (73 mother ewes); Group 3 – supplemented diet from third month of pregnancy to weaning (75 mother ewes). The experiment involved parasitologic tests aimed at the determination of prevalence and intensity of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum of mother ewes before the start of the experiment and on day 2, 28, 42, 56 and 70 after lambing. On the basis of the observations, it was shown that continuous use of the preparation during the whole experimental period had a beneficial impact on reducing the prevalence of invasions of Eimeria spp. and Capillaria. However, it must be stressed that both the prevalence and the intensity of parasitic invasions in the studied flock was relatively low, and so the use of such a preventive method was feasible.
