The study was designed to determine the influence of photoperiod on the nocturnal gene expression of proinflammatory cytokines such as interleukin (IL)-1β (IL1B), IL-6 (IL6), tumor necrosis factor α (TNF) and their receptors: IL-1 type I receptor (IL1R1), IL-6 receptor (IL6R), glycoprotein 130 (IL6ST), TNF type I and II receptors (TNFRSF1A and TNFRSF1B, respectively) in the pars tuberalis (PT) of...
Thirty-two crossbred (Large White × Landrace) gestating sows were used to study the effects of fermented soyabean meal (FSBM) on their reproduction performance and piglet production. Sows were randomly divided into four groups and fed diets containing 0, 5, 10 and 15% FSBM replacing the same amount of soyabean meal, respectively. The experimental periods lasted 58 days including 30 days of pre-farrowing...
Two hundred and forty hens were assigned to six dietary treatments and fed a maize-wheat-soyabean diet supplemented per kg with 0, 150, 350, 550, 750 and 950 mg of marigold flower extract (MFE) containing lutein and zeaxanthin in the amount of 21.26 and 9.65 mg · kg–1 , respectively. There was observed no MFE addition effect on hens body weight and feed conversion ratio. The higher hen-day egg production...
The effects of dietary pomegranate seed oil (PSO) and linseed oil (LO) on the growth performance, slaughter value and fatty acid (FA) profile of breast lipids of broiler chickens were investigated. A total of 400 one-day-old Ross 308 broilers were randomly assigned to 8 feeding treatments, with five replicates per treatment. Between 22 – 42 day of life the birds were fed a grower type diets with four...
This study investigated the supplemental effects of bee pollen (BP) and propolis (bee glue; BG) on broiler performance, intestinal morphometry, haematological profile and biomarkers of heat stress in broilers reared under high ambient temperature. Two hundred and forty one-day-old male broiler chickens were divided into 4 treatment groups: control; BP – supplemented with 20 g of BP · kg–1 of feed;...
In view of expanding cultivation of cereal mixtures, the study was conducted to examine the effects of organic (ORG) vs conventional (CON) farming on fungal contamination, concentrations of phenolic acids (PA) and metals in mixtures of cereals grown in northern and central regions of Poland. The analyses were performed on 10 ORG and 8 CON bulk samples of oat, wheat and barley mixtures, each one comprised...
The effect of fat content in primal cuts of pigs fed diet enriched in the mixture of linseed (2%), rapeseed (0.5%) and fish (0.5%) oils on healthpromoting properties of pork was investigated. Twenty-four crossbred (♂Duroc × ♀(Polish Large White × Danish Landrace)) pigs were fed an experimental diet restrictively from 60 to 105 kg of body weight. After slaughter the right-half carcass was dissected...
The aim of the study was to assess the average daily gain (ADG), the growth rate of linear measurements and cortical index changes of the third metacarpus (ICOR) of foals from 173 ± 8 to 363 ± 12 day of life. Sixteen Mangalarga Marchador weaned colts were divided by age and allotted randomly to one of four dietary treatments (n = 4): A – basal diet (Cynodon pasture + 1.2 kg · 100 kg–1 body weight...
The aim of the experiment was to examine the effect of dietary selenium, vitamins C and E mixture on the antioxidant status and quality of boar ejaculate (Duroc breed). For 90 days the boars were divided into two groups (7 in each group): experimental – fed diet supplemented with (mg · kg–1 of diet) selenium 0.5, vitamin C 350 and vitamin E 70; and control one. The ejaculate samples were collected...
The aim of the study was to evaluate the utilization of maize silage (MS) in moult induction and its effects on immune response and bone quality in laying hens. Laying hens were subjected to 1 of 6 treatments: full-fed (control; FF); total feed withdrawal (positive control for moult induction; FW); 100% MS (M100); 90% MS + 10% layer ration (LR) (M90); 80% MS + 20% LR (M80); and 70% MS + 30% LR (M70)...
The present study was carried out to investigate the potential of different oils nanoemulsions on the modulation of fatty acid proportions and their effect on selected ruminal bacteria using four-fermenter RUSITEC units of 1 l capacity each. Four treatments were investigated: 1. control group (11 g of dried total mixed ration), 2. the control plus soyabean oil (5% on dry matter basis), 3. the control...
The aim of the study was to evaluate the effects of feeding naturally contaminated diet with Fusarium mycotoxins with or without yeast cell wall (YCW) on growth, vulva size, serum protein chemistry and organ weights of gilts. Forty gilts (8.33 ± 0.96 kg) were fed for 30 days four different diets: 1. control, 2. naturally contaminated diet (NCD), 3. naturally contaminated diet + 0.10% YCW, 4. naturally...
The study was conducted on 672 one-day-old female Hybrid Converter turkeys divided into 6 dietary treatments (7 replications per group) which differed in DL-methionine (DL-Met) supplementation levels. The Met content in diets between 1 – 4/5 – 8 weeks of feeding was as follows: 4.1/3.7, 4.7/4.1, 5.6/4.6, 6.1/5.0, 6.8/6.5 and 7.5/7.4 g · kg-1. In groups 3 and 5, dietary Met levels corresponded to those...
The study examined the influence of hybrid, long-term storage and inoculants addition on fermentation profile and grain total zein content in whole plant maize (Zea mays L.) ensiled in laboratory silos. Three yellow maize hybrids were grown under identical conditions in a split-plot field test in five replicates. Replicates were either untreated or mixed with the lactic acid bacterial additive (Sil-All...
The aim of the study was to determine the effect of pelleted cereal-based feed used in the diet for antelope sitatunga ( ) on feed intake, eating behaviour, rumination and nutrient digestibility. Three male sitatunga were fed a basal diet (chopped dehydrated lucerne, ground cereals, soyabean meal, vegetables and fruits) with access to meadow hay. The animals were allocated to 1 of 3 treatments according...
The aim of the study was to evaluate the nutritive value of feedstuffs for giraffes in zoos. In total, 196 samples of six categories of forage (n = 111) and eight categories of non-forage feedstuffs (n = 85) were analysed for chemical composition and in vitro gas production (GP). Lucerne hay as main forage source showed a stable average quality (mean ± standard deviation: crude protein 179 ± 19 g...
The objective of this study was to evaluate the carry-over of transgenic soyabean and maize DNA in samples of milk deriving from different groups of cows fed with either genetically modified (GM) or GM-free feed. Also, to understand the possible source of such contamination of milk which can be of endogenous or exogenous origin (contamination from GM feed containing ‘dust or aerosols’). The milk and...
Protection of the quality of foods such as ground meat, without increased use of antibiotics, is of growing importance. Environmental microbes such as bacteria and yeast are introduced into meat during butchering and processing. Due to the increased surface area of ground meat, the microbial load is higher than in cuts of meat. The presence of non-pathogenic environmental microbes contributes to meat...
Apelin and its APJ receptor are present inter alia in colostrum and in the young animal gastrointestinal tract. This peptide exerts numerous effects participating in the appetite and drinking behaviour, gastric acid and insulin secretion. The aim of the study was to investigate the effect of apelin-13 on the activity of pancreatic and gastric enzymes in young animals. The two experiments were carried...
In homoeothermic vertebrates, one of the most important physiological mechanism concerns the maintenance of the homeostasis. The principal regulator of energy intake is situated in the central nervous system (CNS), where numerous central and peripheral hormones regulate the energy homeostasis. Neuronal pathways between some hypothalamic nuclei create the appetite regulating network in which orexigenic...
