The current knowledge of factors regulating voluntary feed intake in pigs is quite limited. The objective of this study was to test the influence of the missense mutation p.Asp298Asn (AF087937:c.746G>A) of the MC4R gene on selected production traits in pig crosses. These crosses are commonly used on commercial farms in the Czech Republic. The allele frequencies of c.746G>A were as follows: G allele – 0.59 and A allele – 0.41. We detected statistically significant differences in the content of intramuscular fat in the musculus longissimus lumborum et thoracis, and a similar trend was observed in shoulder and neck. A allele correlated with higher values of fatness and G allele with a higher percentage of lean meat. However, we did not find any significant influence on either feed intake or growth rate in this study. For another mutation, p.Arg236His (NM_214173.1:c.707G>A), frequencies of alleles were disproportional (A allele – 0.02 and G allele – 0.98), only two genotypes were observed (AG and GG) and linkage disequilibrium was not detected. Therefore, we assume that the effect of this polymorphism on growth rate and fatness in the Czech population of pigs is negligible.

Rate Selection

Net feed efficiency refers to variation in feed consumption between animals net of requirements for maintenance and production, and may be measured as residual feed intake (RFI). Because RFI is independent of liveweight (LW) and growth rate, selection for improved net feed efficiency is likely to reduce feed intake with little change in growth. The purpose of this study was to establish whether there exists genetic variation in RFI in young British Hereford bulls, and to determine the phenotypic and genetic correlations of RFI with key production traits.The data consisted of performance measurements on 540 bull progeny of 154 British Hereford sires, collected over ten 200-day postweaning performance tests conducted between 1979 and 1988. The traits analysed were food intake (FI), 200 to 400-day daily gain (ADG), 400-day weight (W400), predicted carcass lean content (LEAN), lean growth rate (LGR), food conversion ratio (FI/ADG) and lean FCR (LFCR; FI/(ADG x LEAN), described by Bishop (1992).

Basic Characteristics

The paper deals with the analysis of changes in the development of basic characteristics of the dairy industry in the Czech Republic, which cohere with the integration of the Czech Republic into the European Union. The attention is paid on size of the market, growth rate, life cycle, development of prices and development of foreign trade. The total domestic consumption reached 2111.1 million litres in 2004. The industry is in the maturity. The excess of supply exists in the industry; the growth rate is low, under 5% per year. The integration of the Czech Republic into the EU didn’t bring about changes in the development of basic characteristics – size of the market, growth rate, and life cycle. The volume of production changed. The total volume of purchase of raw milk for production went down by 1.4% to the value in 2000. And all prices in the product vertical – milk and milk products (prices of agricultural producers, production prices and consumer’s prices) rose.The paper is a part of solution of the research plan of the FBE MUAF in Brno, No. MSM 6215648904.

Suffolk Sheep

Lamb growth performance traits in relation to parental breeding values (BVs) for these traits were evaluated in a purebred Suffolk sheep population in the Czech Republic. The research lasted over 8 years and included 24 886 lambs. Four relevant parental BVs were observed: BV predicted for lamb live weight direct effect (BVLW-DE), BV predicted for lamb live weight maternal effect (BVLW-ME), BV predicted for lamb musculus longissimus lumborum et thoracis depth (BV-MLLT), and BV predicted for lamb backfat thickness (BV-BT). The lamb live weight (LW; kg), musculus longissimus lumborum et thoracis depth (MLLT; mm), and backfat thickness (BT; mm) were assessed at 100 days of age. A dataset was created using the most current parental BVs for each year (2007–2014) and subsequent growth traits of their lambs in the next season (2008–2015). Linear regressions showed an increased tendency when one point in dam BVs was associated with an increase in lamb LW (0.393 kg; P < 0.01 in BVLW-DE and 0.090 kg; P < 0.05 in BVLW-ME), MLLT (0.340 mm; P < 0.01 in BV-MLLT), or BT (0.243; P < 0.01 mm in BV-BT). Lower (but significant – P < 0.01) values on linear regression were detected for sire BVs, when 0.135 kg of LW, 0.217 mm of MLLT, and 0.214 mm of BT corresponded to 1-point increases of BVLW-DE, BV-MLLT, or BV-BT. This was confirmed by ANOVA evaluation, especially for LW and MLLT traits. Maximal differences (P < 0.05) in lamb LW were 1.84 kg or 0.88 kg regarding to dam or sire BVLW-DE groups. Similarly, the difference (P < 0.05) in lamb MLLT reached 0.82 mm in dam BV-MLLT, while 0.57 mm was detected in sire BV-MLLT groups. These results have practical implications for the objectives of selection schemes used in the Suffolk sheep population in the Czech Republic.

The main objective of the study was a comparative analysis of the diversity of the agrarian structure and the productivity of land and labour in the Visegrad Group countries. Additionally, the importance of the Visegrad Group in the European Union was analysed in relation to the size of the production of selected crops and livestock as well as the population and cast of cattle and pigs. According to the conducted analyses, the highest productivity of land among the countries of the Visegrad Group was shown in the years under study by Poland and Hungary (over EUR 600 / ha AL), while the highest dynamics of the growth rate of this parameter - by Slovakia (almost two-fold increase in 2010-2013). Taking into account labour productivity, it should be emphasized, that the greatest labour productivity characterized farms in the Czech Republic and Slovakia.

Post Mortem Findings

The aim of the study was to assess post-mortem findings according to their localization and the nature of damage and to assess the standard of health and welfare of farmed rabbits on the basis of these findings. A total of 40,206 pathological findings were recorded in 1,876,929 rabbits slaughtered at slaughterhouses in the Czech Republic in the period from 2010 to 2019. Pathological findings on the limbs (0.84%), the trunk (0.71%), the kidneys (0.17%), and the liver (0.05%), along with generalized changes (0.37%), occurred most frequently. Findings of traumatic origin dominated among findings on the limbs and trunk, which indicates the inappropriate housing and handling rabbits on farms and during transport. Findings in the kidneys and liver were most often of a chronic nature having an evident correlation with the diet of intensively fed rabbits, with shortcomings in the diet having an impact on the parenchyma with chronic manifestations in the liver and kidneys. Among the generalized findings, multiple abscesses, which were probably associated with the infection of injuries occurring during fattening, and emaciation resulting from current husbandry practices, leading to insufficient feed intake or the development of disease in some individuals, predominated.

A New Species

This work reports the identification of Trachelomonas saccasii in a small mesotrophic pond in the Czech Republic. Trachelomonas saccasii was originally described from a small lake in Ivory Coast (West Africa) in 2009. This report from the Czech Republic is the second known record of this taxon after the initial description of this species. Trachelomonas saccasii represents a new species of euglenoid for the Czech Republic and Europe. This finding highlights the current knowledge gaps regarding the biogeography and worldwide distribution of euglenoids. The first aim of this study is to describe the identification of Trachelomonas saccasii using light and scanning electron microscopy and to compare it with the description of the original material from Africa. Second, we discuss the current knowledge of euglenophyte biogeography and propose methods that could be used to explore biogeographical distributions using floristic databases. These methods could be useful especially for the following flagship species: Colacium epiphyticum, C. minimum, Lepocinclis crassicollis, Phacus plicatus, Trachelomonas argentinensis, T. hemispherica and T. magdaleniana. This study provides new data on the global distribution of euglenoids and proposes possible strategies to obtain further information about the global distribution of this group of microorganisms.
