This study evaluated the effects of dietary replacement of soyabean meal (SBM) with yellow lupine seed meal (YLM) in turkeys. A total of 1120 one-day-old Hybrid Converter female turkeys were fed diets containing 0%, 8%, 16% and 24% of YLM (LM0 , LM8 , LM16, LM24, respectively) in a 16-week experiment. In the first phase of feeding (weeks 0–4), an increase in the YLM content of diets caused a linear...
Postprandial oxidative losses of egg white-bound [1-13C]-leucine were studied as 13C recovery in the breath of rats in relation to different time intervals between two meals. Male Wistar rats (n = 48; 68.3 ± 5.9 g) divided into 4 groups (n = 12) were fed two meals a day (9:00 and 16:30; interval 7 h) of a 13.2% egg white-based diet for 30 min. After 14 days, 3 out of the 4 groups received the 2nd...
The study examined the effect of xylanase supplementation on apparent metabolizable energy (AME) and hepatic vitamin E and carotenoids in broiler chickens fed wheat based diets. A total of one hundred forty four male Ross 308 chickens were used in this study. Birds were randomly assigned to 3 dietary treatments (8 cages per treatment of 6 male broilers each) for 14 days from 7 to 21 day old. The control...
The experiment was performed according to a 2 x 2 factorial design with breed and level of nutrition as factors affecting fat metabolism in pigs. Two groups of gilts, each comprising 4 Polish Large White (PLW) and 4 Synthetic Line 990 (L990) animals, were fed from 60 to 105 kg body weight on the experimental diet at 85% or 95% of assumed ad libitum intake. The diet contained 2% of linseed, 0.5% rapeseed...
The objective of this study was to evaluate the effect of different fiber sources on jejunal digestive and absorptive physiology in weaned piglets. One hundred weaned piglets were allotted according to body weight, gender and litter to four dietary treatments. Each treatment was replicated in 5 pens of 5 pigs each. The experimental diets contained 10% of a fiber source: wheat bran (WB), maize fiber...
To evaluate the effects of silicic acid powder containing bamboo vinegar liquid (SPV) on growth performance, carcass traits and intestinal histology, 80 male broilers at 7 days of age were divided into four treatment groups, each with four replicates of five chickens. The birds were fed ad libitum a basal diet supplemented with SPV at a level of 0%, 0.1%, 0.2% or 0.3% until 49 days of age. Body weight...
The objective of this study was to verify the hypothesis that adding dried fruit pomaces differing in their polyphenol contents to diets for young turkeys does not compromise bird performance. Young turkeys aged up to 15 weeks were fed diets containing a cellulose preparation (C) or 5% dried apple pomace (AP), blackcurrant pomace (BCP), strawberry pomace (SP), or seedless strawberry pomace (SSP)....
The experiment was performed to determine whether transgenic maize containing the Bt gene (MON 810) and soyabean meal produced from glyphosate-tolerant plants (Roundup Ready, MON 40-3-2) compared with nontransgenic plants can affect the performance parameters, milk composition, blood serum metabolite profiles and transfer of tDNA into milk of cows. The experiment was carried out from the third week...
The rumen simulation technique (RUSITEC) was used to evaluate the effect of two levels of echium (Echium plantagineum) oil (EO) on methano-genesis. Treatments comprised: control (commercial total mixed ration for lactating dairy cows; positive control), control supplemented with sodium 2-bromoethanesulfonate (5 mM on a dry matter (DM) basis; negative control; BES) and control supplemented with 4%...
Different equations were employed to directly model individual lactation curves of Tunisian Holstein-Friesian cows using 260 241 test day records for milk yield, fat, and protein contents. Eleven mathematical models were compared. Parametric curves (Legendre polynomials, Ali and Schaeffer (AS), Wood, and Wilmink models) and regression splines were tested. Goodness of fit was assessed by considering...
A major problem in sheep rearing is scarcity of feed during the summer and winter in semi-arid tropics. A study was conducted to assess the sperm motion characteristics and sexual behaviour of Garole x Malpura x Malpura (GMM) rams subjected to nutritional stress. Eighteen adult GMM rams were randomly allocated into three groups of six animals each: G1 (control; fed maintenance requirement), G2 (fed...
The “hoped for” reduction in the use of antibiotics in pig by EU producers has not been materialized as they are still being widely used for the control of enteric infectious diseases. This practice can spread antibiotic resistance in the farm environment and poses a threat to consumer health. Whilst it is widely recognized that a diversified gastro-intestinal tract (GIT) microbiota is essential for...
The effects of genetically modified (GM) soyabean meal (SBM) and GM maize on the functional status of the small intestine of broiler chickens was studied. Eight diets were prepared, based on conventional or GM SBM (GTS 40-3-2) combined with non-modified maize cvs. Clarica and PR39 F58 or their isogenic GM (MON 810) counterparts cvs. Bacilla or PR39 F56. Diets were fed in mash form from days 1 to 30...
The expression of genes encoding opioid precursors: proopiomelanocortin (POMC), proenkephalin (PENK) and prodynorphin (PDYN) was studied in the porcine endometrial explants in the presence or absence of selected cytokines (interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor α (TNFα)) on days 10–11, 12–13, 15–16 of the oestrous cycle and pregnancy. In pregnant pigs, these days among...
The foliage of woody plants, Artemisia herba alba (ART), Eucalyptus globulus (EUC), Pistacia lentiscus (PIS), Rosmarinus officinalis (ROS) and Thymus capitatus (THY), growing in central Tunisia was analysed for contents of nutrients and phytocompounds, including essential oils (EOs) and tannins. PIS and THY were highest in neutral detergent fibre and condensed tannins, respectively. EUC had the highest...
Aquaculture dependency on component feed has increased attention to alternative feedstuffs for conventional ingredients such as fish meal, oil seeds and grains. The main aim of this study was to evaluate growth performance, nutrients digestibility and body composition in common carp (Cyprinus carpio) fed diet with different levels of tomato pomace. Four experimental diets were formulated with similar...
The aim of the study was to analyse the annual changes in the concentration of free triiodothyronine, progesterone and testosterone in the serum of prepubertal red deer males and females. Blood was collected monthly from 8 stags and 8 hinds for a period of one year, beginning in November. Hormone concentrations were determined using an immunofluorescence method (TR-FIA). Monitoring of the duration...
This study evaluated the effect of thyme (Thymus vulgaris L.) on productive performance, egg quality, blood profile, immune function and antioxidant enzyme activity in laying hens. A total of 96 thirty-six-week-old laying hens were assigned to a basal control diet or a diet supplemented with 3, 6, or 9 g · kg–1 of thyme fed from 36 to 52 weeks of age. Hens were divided into four equal groups replicated...
The effects of calcium propionate supplementation on performance, meat quality, and mRNA expression of Wagyu steers were investigated. Eighteen steers (635 ± 20 kg; 18 ± 1 month old) were randomly divided into two groups: control (CG, without calcium propionate) and experimental (CaP, 200 g calcium propionate per steer per day). All steers were reared for 51 days under the same production system and...
The effects of genetically modified (GM) soyabean meal (SBM) and GM maize (MON 810) on the performance and immunological response of broiler chickens were studied. Eight diets were prepared based on conventional or GM SBM (GTS 40-3-2) combined with non-modified maize cvs. Clarica or PR39 F58 or their isogenic GM counterparts, cvs. Bacilla or PR39 F56. Diets were fed in mash form from day one of age...
