In two experiments with weaned piglets, the effects of fermented liquid feed (FLF) (produced with probiotic strain Pediococcus acidilactici, Bactocell®, Lallemand S.A.S.) on performance and some bacteriological and morpho-histological parameters of the gut were investigated, and the impact of sedimentation of the solids in the FLF thereon. In experiment I, FLF or the same dry feed (DRY) was offered ad libitum for 28 days to two groups of 15 weaned piglets (28 days of age) each (3 replicates of 5 pigs). Performance was negatively affected by feeding FLF and concomitant with that the group fed the FLF diet showed shorter...

The Trivers-Willard hypothesis (TWH) predicts the ability of mothers to adaptively adjust offspring sex ratio through differential maternal investment based on their relative body condition. In the present study we have analyzed an extensive data set on the secondary sex ratio (SSR) including 59 335 goat kids born in 30 633 litters to 11 644 mothers on farms all over the Czech Republic during the years 1992-2004. We found a male-biased SSR 0.568, which significantly deviates from the predicted balanced Fisherian equilibrium 1 : 1 (P < 0.0001). A generalized estimating equation model controlled for mother's identity revealed a significant...

This study investigated the genetic relationship between 6 populations of Welsh Mountain sheep: 5 phenotypic breed-types within the Welsh Mountain (WM) sheep breed, which have each been bred in specific geographic areas of Wales, and the Black Welsh Mountain sheep breed. Based on DNA analysis using 8 microsatellite markers, observed heterozygosity levels were similar to those expected in livestock populations subjected to selective breeding (0.530-0.664), and all but one population showed evidence of inbreeding. Using Bayesian cluster and Neighbor-joining analyses, the Black Welsh Mountain sheep were identified as being the outlier group, and the remaining...

Effects of different levels of Biomin® IMBO synbiotic, including Enterococcus faecium (as probio-tic), and fructooligosaccharides (as prebiotic) on survival, growth performance, and digestive enzyme activities of common carp fingerlings (Cyprinus carpio) were evaluated. The experiment was carried out in four treatments (each with 3 replicates), including T1 = control with non-synbiotic diet, T2 = 0.5 g/kg synbiotic diet, T3 = 1 g/kg synbiotic diet, and T4 = 1.5 g/kg synbiotic diet. In total 300 fish with an average weight of 10 ± 1 g were distributed in 12 tanks (25 animals per 300 l) and were fed experimental...

Iron (Fe) is an essential mineral for animal development and function. The present study was carried out to evaluate the effect of replacing FeSO4 with iron glycine chelate (Fe-Gly) in the equal Fe level in diets on broiler chickens. The broilers were randomly allotted to 6 dietary treatments with 5 replicate pens and 10 birds per pen. The treatments consisted of: Control group (100 mg Fe from FeSO4/kg diet), Experimental group 1 (80 mg Fe from FeSO4 + 20 mg Fe from Fe-Gly/kg diet), Experimental group 2 (60 mg Fe from FeSO4 + 40 mg Fe from Fe-Gly/kg diet), Experimental group 3 (40 mg Fe from FeSO4 +...
