    Abstract We reviewed the available records on aberrantly coloured fat dormice Glis glis and are reporting on two recent cases of flavistic males. We identified five colour variants among nearly 11,000 dormice from throughout their range in Europe and Asia (of these 6174 from Slovenia and Croatia, and 3493 from the Czech Republic). Flavistic dormice come from Slovenia and Czechia (two cases each) while all the remaining colour variants were recorded in Slovenia between 1860 and 2012: melanistic (20 inds.), albino (7 inds.), isabellinus (4 inds.), and individuals with white tail stripes (five cases). The two flavistic individuals from Czechia were captured during a demographic study. Interestingly, the aberrant pelage was gained by both males later in life as in the years of first encounter they had the typical greyish coat colouration.

    Abstract This study aimed to determine the optimal dietary niacin requirement of juvenile Megalobrama amblycephala. Fish, with an average weight of 3.62 ± 0.02 g, were randomly divided into six groups and fed six purified diets with graded levels of niacin (0, 10, 20, 30, 40 and 50 mg/kg) three times daily for 8 weeks. The survival rate, weight gain (WG), feed conversion ratio, protein efficiency and protein retention all significantly improved (p < .05) as the dietary niacin level increased from 0 to 30 mg/kg but showed no significant difference (p > .05) with further increases in niacin levels. The supplementation of 30 mg/kg niacin also led to a significant (p < .01) reduction in the viscerosomatic index, hepatosomatic index and mesenteric fat index. The dietary niacin levels exhibited minimal effects on whole‐body moisture and ash content (p > .05) but exerted a significant (p < .05) influence on protein and lipid contents and liver nicotinamide concentrations with high values obtained in fish receiving greater than 30 mg/kg of niacin. In addition, moderate levels of niacin lowered plasma triglycerides, non‐esterified fatty acid and low‐density lipoprotein cholesterol concentrations (p < .05). Based on the broken‐line regression analysis of WG and liver nicotinamide content, the optimal dietary niacin requirement of juvenile blunt snout bream was 31.25 and 30.62 mg/kg, respectively.

    Abstract An 8‐week feeding trial was performed to investigate effects of dietary selenium (sodium selenite, Na₂SeO₃; selenium nanoparticle, Nano‐Se; selenium yeast, Se‐yeast) on the growth, selenium status, antioxidant activities, muscle composition and meat quality of blunt snout bream. Na₂SeO₃ and Nano‐Se were supplemented at 0.2 mg Se kg⁻¹, and Se‐yeast was supplemented at 0.1, 0.2, 0.4 and 0.8 mg Se kg⁻¹ in basal diet; no Se was added as a control. The results indicated that groups of 0.2 and 0.4 mg kg⁻¹ Se‐yeast had significantly higher weight gain and Nano‐Se, 0.2, 0.4 mg kg⁻¹ Se‐yeast had significantly lower feed conversation ratio compared with the control group. The Se concentrations of whole body, muscle and liver linearly increased with increasing dietary Se‐yeast levels. Group of 0.4 mg kg⁻¹ Se‐yeast significantly increased activities of catalase and glutathione peroxidase. Muscle colour of Nano‐Se, 0.2, 0.4 mg kg⁻¹ Se‐yeast groups, the water‐holding capacity of 0.4, 0.8 mg kg⁻¹ Se‐yeast groups showed significant differences compared with the control group. The results suggest that Se‐yeast and Nano‐Se had a better growth performance than Na₂SeO₃ at 0.2 mg Se kg⁻¹, and supplementing appropriate Se‐yeast in diet can increase antioxidant activities and enhance meat quality of blunt snout bream.

    Abstract Two feeding trials (FTs) were conducted in 2013 and 2014, respectively, to determine the optimal L‐malic acid (LMA) level for juvenile GIFT (Genetically Improved Farmed Tilapia) Oreochromis niloticus. Except for the LMA level, the FT1 and FT2 had a similar diet formulation. In FT1, LMA was included at 0 (basal diet), 1, 4, 8, 16 and 32 g kg⁻¹, respectively. After 20 weeks, daily weight gain and feed conversion ratio were improved but not differentiated with 1–8 g kg⁻¹ LMA. Further increasing the LMA supply initially decreased the feed intake (16 g kg⁻¹), and then decreased both feed intake and feed utilization (32 g kg⁻¹), thus impairing the fish growth. FT2 was subsequently conducted with a smaller LMA range (0, 0.5, 1, 2, 4 and 8 g kg⁻¹, respectively) but was unfortunately terminated at the end of 8 weeks because 20% of the fish were badly injured during weighing. Unexpectedly, growth and feed utilization were still improved but not differentiated with 0.5–8 g kg⁻¹ LMA. In FT2, beneficial effects of LMA inclusion on the digestive function (pepsin, foregut amylase and foregut lipase), the activities of serum lysozyme and hepatic superoxide dismutase, and liver lipid peroxidation (malondialdehyde concentration) were found. Taking the results of FT1 and FT2 together, it could be concluded that dietary LMA supplementation at low concentrations (0.5–8 g kg⁻¹) could improve growth and feed utilization, but excess LMA (≥16 g kg⁻¹) might compromise feed intake and/or feed utilization, thus impairing fish growth. To reduce feed costs in commercial practice, 0.5 g kg⁻¹ LMA is recommended in the feed of juvenile GIFT tilapia based on the results of this study.

    Abstract An 8‐week feeding trial was conducted to evaluate the potential of partial replacement of fish meal with rendered animal protein blend (APB) [meat and bone meal (MBM): expanding blood meal (EBM) = 4 : 1] in the diet of juvenile Chinese soft‐shelled turtle Pelodiscus sinensis. Seven isonitrogenous and isoenergetic practical diets replacing 0%, 10%, 20%, 30%, 40%, 50% and 60% fish meal protein by APB were formulated. Weight gain, feed efficiency, protein efficiency and the apparent digestibility coefficients (ADCs) of dry matter and gross energy in the experimental diets all exhibited no significant difference (P > 0.05) when dietary fish meal was replaced for 0–40%, but decreased significantly (P < 0.05) with further increasing substitution levels. However, relative feed intake, ADC of lipid as well as the contents of whole‐body moisture, protein, lipid and ash all showed little differences (P > 0.05) among all the treatments. Nitrogen retention and the ADCs of protein and most amino acids all decreased significantly (P < 0.05) when fish meal was substituted by more than 30%. The results indicated that fish meal in the practical diet of juvenile Chinese soft‐shelled turtle could be replaced by 30–40% using a combination of MBM and EBM without negative effects on growth performance, nutrients digestibility and body composition.

    Abstract Five 2‐week feeding trials were conducted to investigate five stimulants on P. sinensis. Two isonitrogenous and isoenergetic diets were formulated, one contained 600 g kg–¹ fishmeal (FM diet) and the other contained 420 g kg–¹ fishmeal and 225 g kg–¹ animal protein blend (APB diet), and each tested one stimulant with four levels. The feeding stimulant candidates were betaine, 2‐carboxy‐ethyl dimethyl sulphonium bromide (DMPT), inosine‐5′‐monophosphate (IMP), taurine and squid extract. In the experiment on each stimulant, turtles (10.85 ± 0.10 g) were equally divided into FM and APB groups and fed with an equal mixture of corresponding diets containing four levels of stimulants, respectively. Each diet contained a unique rare earth oxide as inert marker. Turtles were fed twice daily (8:00 and 17:00), and faeces were collected. Preference for each diet was estimated based on the relative concentration of each marker in the faeces. In the FM group, only IMP showed the enhanced attraction. But in APB groups, all the stimulants, except IMP, showed higher preference than basal diets for at least one inclusion level, and the optimum level was 10 g kg–¹ for betaine, 0.1 g kg–¹ for DMPT, 0.1 g kg–¹ for IMP, 5 g kg–¹ for taurine and 10 g kg–¹ for squid extract, and the squid extract had the strongest stimulating effect among the stimulants.

    Abstract An 8‐week feeding trial was conducted to evaluate the effects of fish meal (FM) replacement by rice protein concentrate (RPC) with supplementation of microcapsule lysine (ML) or crystalline lysine (CL) on growth performance, muscle development and flesh quality of blunt snout bream. Four isonitrogenous and isoenergetic diets were formulated, including FM diet (containing 50 g/kg FM), RPC diet (FM replaced by RPC), MRPC diet (FM replaced by RPC with ML supplementation) and CRPC diet (FM replaced by RPC with CL supplementation). Fish fed FM diet had significantly higher weight gain, feed efficiency, protein efficiency ratio and nitrogen and energy utilization than that of RPC group, but showed no statistical difference with other treatments. In addition, fish fed RPC diet showed higher muscle fibre frequency in the 20‐ to 50‐μm class but lower >50‐μm class and higher cooking loss than that of the other groups. Furthermore, no significant difference was found in whole‐body proximate compositions, frequency distribution of <20‐μm‐diameter fibres, texture, muscle content, collagen, pH 24 hr post‐mortem and sensory quality. The results showed that RPC supplemented with ML or CL could replace fishmeal without any adverse effects on growth performance and flesh quality for blunt snout bream.

    Abstract A new dark sector antibaryon, denoted ψ_{D}, could be produced in decays of B mesons. This Letter presents a search for B^{+}→ψ_{D}+p (and the charge conjugate) decays in e^{+}e^{-} annihilations at 10.58 GeV, using data collected in the BABAR experiment. Data corresponding to an integrated luminosity of 398  fb^{-1} are analyzed. No evidence for a signal is observed. Branching fraction upper limits in the range from 10^{-7}-10^{-5} are obtained at 90% confidence level for masses of 1.0<m_{ψ_{D}}<4.3  GeV/c^{2}. The result is also reinterpreted to provide the first limits on a supersymmetric model with R-parity violation and a light neutralino.<br />

    Abstract Using the entire BaBar $\Upsilon(4S)$ data set, the first two-dimensional unbinned angular analysis of the semileptonic decay $\overline{B} \rightarrow D \ell^- \overline{\nu}_\ell$ is performed, employing hadronic reconstruction of the tag-side $B$ meson from $\Upsilon(4S)\to B\overline{B}$. Here, $\ell$ denotes the light charged leptons $e$ and $\mu$. A novel data-driven signal-background separation procedure with minimal dependence on simulation is developed. This procedure preserves all multi-dimensional correlations present in the data. The expected $\sin^2\theta_\ell$ dependence of the differential decay rate in the Standard Model is demonstrated, where $\theta_\ell$ is the lepton helicity angle. Including input from the latest lattice QCD calculations and previously available experimental data, the underlying form factors are extracted using both model-independent (BGL) and dependent (CLN) methods. Comparisons with lattice calculations show flavor SU(3) symmetry to be a good approximation in the $B_{(s)}\to D_{(s)}$ sector. Using the BGL results, the CKM matrix element $|V_{cb}|=(41.09\pm 1.16)\times 10^{-3}$ and the Standard Model prediction of the lepton-flavor universality violation variable $\mathcal{R}(D)=0.300\pm 0.004$, are extracted. The value of $|V_{cb}|$ from $\overline{B} \rightarrow D \ell^- \overline{\nu}_\ell$ tends to be higher than that extracted using $\overline{B} \rightarrow D \ell^- \overline{\nu}_\ell$. The Standard Model $\mathcal{R}(D)$ calculation is at a $1.97\sigma$ tension with the latest HFLAV experimental average.

    Abstract Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be emitted in flavor-changing B meson decays. We report herein a search for an ALP, a, in the reaction B^{±}→K^{±}a, a→γγ using data collected by the BABAR experiment at SLAC. No significant signal is observed, and 90% confidence level upper limits on the ALP coupling to electroweak bosons are derived as a function of ALP mass, improving current constraints by several orders of magnitude in the range 0.175  GeV<m_{a}<4.78  GeV.<br />
