Co-feeding of fish larvae with live food and formulated diet has been at the focus of fish nutritionists since last decade. In this study we tried to refine the feeding practices of great beluga sturgeon (Huso huso) larvae using different combinations of newly hatched Artemia urmiana nauplii and trout starter diet. Three replicate groups (250 fish/replicate) of first-feeding Huso huso ...

the aim followed in the present paper was to evaluate the slaughter body and carcass weights as well as the characteristics of hide and leather in dromedaries (one-hump) and in the crossbred (c. bactrianus×c. droedarius) camels. fourteen camels from each sex (female and male) representing two genotypes at 21 months of age were utilized. slaughter weight, hot and cold carcass weights, dressing-o...

Muscular strength is an important component of physical fitness and can be improved by using free weights (i.e. barbells, dumbbells), weight machines, elastic bands, or body weight exercises (Stone et al., 2000). A new product in the exercise marketplace which is advertised to increase strength is the Shake Weight ®. The Shake Weight ® is a dumbbell shaped fitness device, sold by Fitness IQ (Vi...

the aim of the peresent study was to find the optimum weaning time to shift pikeperch larvae feeding from live food to the artificial feed. in this experiment, pikeperch larvae were fed with seived pond zooplankton (mainly rotifers) and artemia nauplii from the first feeding day to day 16 of post-hatching. then three weaning times were used on day 16 (w16), day 22 (w22), and day 28 (w28) of pos...

This research has been carried out to investigating of some biological aspects of date mussels, Lithophaga lithophaga distributing in Gulf of Antalya, in February 2015 – January 2016. The samples were used to determine length and live weight frequency distributions (nonlinear regression using the allometric function), size (length, breadth, thickness) – size relationship (linear regression). Th...

Merino yearling records from 1988 to 1992 birth years in ultrafine wool selection and random control flocks at Tara Hills High Country Station, New Zealand were analysed for live weight, fleece weight and wool characteristics. Estimates of heritability, genetic and phenotypic correlations among traits using REML methods are presented. Heritabilities (h2) of birth, weaning, autumn, spring and su...

The objective of this study was to identify risk factors for low birth weight in singleton live born infants in Rio Grande do Sul State, Brazil, in 2003, based on data from the Information System on Live Births. The study used both classical multivariate and multilevel logistic regression. Risk factors were evaluated at two levels: individual (live births) and contextual (micro-regions). At the...

An experiment designed to assess the effect of two grazing pressures (GP, expressed as kg MS/100 kg LW) and four levels of supplement (0, 0.25, 0.50 and 0.75 expressed as kg/100 kg LW) fed to yearling heifers (212 kg) on live weight gain, was carried out at the Dairy Unit of INIA La Estanzuela (Uruguay). The experiment consisted of 8 treatments. Forty animals were used in the experiment, 5 per ...
