Impact of the mare colostral immunoglobulins on the expression of TLR3, TLR4, and TLR7 in foals.

Colostrum contains substances such as hormones, enzymes, polyamides, nucleic acid derivatives, and amino acid derivatives and also includes immunomodulating substances, proline-rich polypeptides, immunoglobulins (Ig) as well as bacteriostatic compounds. The aim of the study was to evaluate the impact of colostral Ig on the level of expression of selected Toll-like receptor genes (TLR3, TLR4, and TLR7). The experiments were conducted on 25 Polish Pony foals.

A Study on the Modifying Effect of Raspberry Seed Oil on Rabbit Meat Quality and Chemical Composition.

The purpose of the study was to determine the effects of raspberry seed oil on the slaughter performance traits, plasma lipid concentration and meat quality of purebred Termond White rabbits ( = 42; 18♂, 24♀). In each group (3 × = 14; 6♂, 8♀), the experimental animals were fed a complete pelleted feed with constant access to drinking water. Rabbits in the first experimental group received a feed ration enriched with a 1% addition of raspberry seed oil, while rabbits in the second experimental group were given a 2% addition of the same oil.

Polymorphism within Genes Affects the Acidity, Colour, and Shear Force of Rabbit Meat.

Rabbits are important livestock animals, popular for their nutritional value. Nowadays, the molecular background of traits influencing the quality of meat and meat products is in high demand. Therefore, in the current study, we analyse the sequences of , , , , and for possible polymorphisms.

Effectiveness of immunization with multi-component bacterial immunomodulator in foals at 35th day of life.

The aim of the study was to investigate the mechanisms leading to immunization through the use of a multicomponent bacterial immunomodulator and to find out the relationship between the TLR 4 receptor with selected parameters of innate immunity and to acquire immunity. The study was conducted on 18 Polish Pony Horses foals divided into two study groups: control (n = 9) and experimental (n = 9). Foals from the experimental group received intramuscular duplicate injection of 5 ml of multi-component bacterial immunomodular at 35 and 40 days of age.

Effect of a Diet Supplemented with Nettle ( L.) or Fenugreek ( L.) on the Content of Selected Heavy Metals in Liver and Rabbit Meat.

The literature on herbal additives for rabbit feed offers little information on the use of nettle and fenugreek. Both of these herbs are valuable sources of vitamins and minerals. These herbs affect the growth, health, and meat quality of rabbits.

Meat Quality of the Native Carpathian Goat Breed in Comparison with the Saanen Breed.

Goats provide valuable products that are appreciated by consumers who are looking for food that is not only tasty but also healthy, and, probably, one of them is goat meat. Breeding of local breeds such as the native Carpathian goat has been gaining importance in recent years, which creates an opportunity for the development of the goat meat market. The aim of this study was to investigate the influence of goat breed on the basic chemical, fatty and amino acid composition, colour and sensory evaluation of meat.

Effect of a Diet Supplemented with Nettle ( L.) or Fenugreek ( L.) on the Post-Slaughter Traits and Meat Quality Parameters of Termond White Rabbits.

The purpose of the study was to analyse the effect of nettle ( L.) leaves and fenugreek ( L.) seeds as additives to fodder in order to improve post-slaughter traits and quality parameters of Termond White rabbit meat (n = 60; 30♂, 30♀).

Non-Invasive Measurement of Thyroid Hormones in Domestic Rabbits.

Thyroid hormones are essential for metabolism, energy homeostasis and reproduction. Hormones can be measured in various biological source materials: blood, feces, urine, saliva and others. The aim of our study was to verify usefulness of thyroid hormone analysis in the urine and feces of the domestic rabbit (), comparing them with the serum analyses.

Rapid Assessment of SARS-CoV-2 Transmission Risk for Fecally Contaminated River Water.

Following the outbreak of severe acute respiratory syndrome coronavirus (SARS-CoV-2), airborne water droplets have been identified as the main transmission route. Identifying and breaking all viable transmission routes are critical to stop future outbreaks, and the potential of transmission by water has been highlighted. By modifying established approaches, we provide a method for the rapid assessment of the risk of transmission posed by fecally contaminated river water and give example results for 39 countries.

The Quality and Health-Promoting Value of Meat from Pigs of the Native Breed as the Effect of Extensive Feeding with Acorns.

The popularity of meat from animals of native breeds is growing all over the world, due to consumer belief regarding its higher quality compared to meat from industrial farm animals. In addition, the living conditions (welfare) are of great importance for consumers. We observed the effect of different ways of keeping and feeding pigs of the same conservative breed on the quality of meat and its health benefits.

Influence of Age and Immunostimulation on the Level of Toll-Like Receptor Gene (, , and ) Expression in Foals.

The aim of this study was to investigate the molecular mechanisms leading to the identification of pathogens by congenital immune receptors in foals up to 60 days of age. The study was conducted on 16 foal Polish Pony Horses (Polish Konik) divided into two study groups: control ( = 9) and experimental ( = 7). Foals from the experimental group received an intramuscular duplicate injection of 5 mL of Biotropina (Biowet) at 35 and 40 days of age.

Influence of sulpiride treatment on the level of prolactin and immunoglobulins in the peripheral blood of mares during the postpartum period.

The aim of this study was to determine the effect of increased levels of prolactin (PRL) on the concentration of immunoglobulins in the blood, colostrum and milk of mares. The study was conducted on 12 mares of the Polish Pony breed (6 in the control and 6 in the experimental group). To induce hyperprolactinaemia in mares of the experimental group, 750 mg sulpiride was administered orally once a day.

Mutations in Leptin (LEP) Gene Are Associated with Carcass and Meat Quality Traits in Crossbreed Rabbits.

Leptin is a hormone synthesized and secreted primarily in adipose cells that help to regulate energy balance. This study examined the associations of single nucleotide polymorphisms in the rabbit leptin gene with growth traits, slaughter traits and physicochemical parameters of New Zealand White (NZW) and Belgian Giant Grey (BGG) crossbreed rabbits. In total, 320 crossbreed animals were genotyped for polymorphisms within exon 2-g.

Cross Species Amplification of Coat Colour Genes in Nutria (Myocastor coypus Mol).

In this study, nutria-specific DNA fragments were amplified with cross-species primers for parts of coat colour genes (MC1R, ASIP, TYRP-1, c-KIT) conserved across a number of species. Twenty-three nutria-specific DNA fragments were generated using cross-species PCR (26.7% amplification success rate).
