Forty-eight gilts were submitted to a 30% restriction of feed (groups F and F1) or protein intake (group P) from 90 to 118 days of age, followed by realimentation from 119 to 168 days of age. Control pigs (C) were fed during the whole experiment according to a semi ad libitum scale. During realimentation all animals were fed according to semi ad libitum(More)
Pigs of Belgian Landrace (B), Duroc (D), Hampshire (H), and Pietrain (P) breeds were slaughtered at 90, 110 and 130 kg body weight (BW) and the carcass chemical composition and fatty acid profiles of intramuscular fat of loin and backfat were determined. The carcass of Pietrain pigs had a higher concentration of protein and less fat than of B, D and H(More)
The study determined the emotional reactions of consumers in relation to hams using face visualization method, which was recorded by FaceReader (FR). The aims of the research were to determine the effect of the ham samples on the type of emotion, to examine more deeply the individual emotional reactions of consumers and to analyse the emotional variability(More)
This study was carried out on 24 gilts (♀ Polish Large White × ♂ Danish Landrace) grown with body weight (BW) of 60 to 105 kg. The pigs were fed diets designed on the basis of a standard diet (appropriate for age and BW of pigs) where a part of the energy content was replaced by different fat supplements: linseed oil in Diet L, rapeseed oil in Diet R and(More)
All nutrients including proteins, lipids, vitamins, minerals and growth factors required by the developing embryo, as well as a number of defense factors, can be found in avian eggs. Eggs are also a source of other substances with biological functions and activities inter alia immune proteins and enzymes. Although chicken egg consumption is currently at the(More)
The research was carried out on 32 crossbred pigs of Polish Large White × Danish Landrace with Duroc and 80 rams, crossbreds of the Prolific-Dairy Koludzka Sheep with the Ile de France, a meat sheep. The fodder for the animals was enriched with the unsaturated fatty acids originated mainly from linseed and rapeseed oils. The fatty acid profile was(More)
The main purpose of present review is to describe and organize autosomal recessive disorders (arachnomelia, syndactylism, osteopetrosis, dwarfism, crooked tail syndrome, muscular hyperplasia, glycogen storage disease, protoporphyria), which occur among beef cattle, and methods that can be applied to detect these defects. Prevalence of adverse alleles in(More)
The level of omega-6 and omega-3 polyunsaturated fatty acids can affect many cellular systems and function via nuclear receptors or the bioactive lipid regulation of gene expression. The objective of this study was to investigate changes in the muscle transcriptome and the biological functions regulated by increased consumption of omega-3 and omega-6 fatty(More)
The optimal ratio of omega-6 to omega-3 polyunsaturated fatty acids (PUFAs) is important for keeping the homeostasis of biological processes and metabolism, yet the underlying biological mechanism is poorly understood. The objective of this study was to identify changes in the pig liver transcriptome induced by a diet enriched with omega-6 and omega-3 fatty(More)
Limited information on physiological characteristic of bones in ostrich skeleton are available, even though bone weaknesses in ostriches are commonplace. Thus, the aim of this study was to evaluate morphological, densitometric, and mechanical properties of pelvic limb long bones (femur, tibia, and tarsometatarsus) in 14-month-old female ostriches (Struthio(More)
