It was assumed that the industry of beef cattle breeding being created in Krasnodar Territory would meet needs population beef. Due to fact there are not enough cattle, dairy bulls raised and fattened. Positive results obtained case when, along with an increase number fattened livestock animals, their intensive rearing feeding is introduced. In our studies, fattening Holstein Black-and-White bu...

Currently, the general trend of global fishing industry is to increase production fish food products not only due development aquaculture, but also biological characteristics body sturgeon. The aim study was theoretical justification and practical implementation assessment growth beluga juveniles their hybrids with sterlet aged 0+ 2+ (three-year-olds) in industrial Krasnodar Territory. determin...

We consider estimates of the parameters of GARCH models of daily nancial returns, obtained using intra-day (high-frequency) returns data to estimate the daily conditional volatility. We obtain asymptotic properties of the estimators and o er some simulation evidence on small-sample performance, and characterize the gains relative to standard quasi-ML estimates based on daily data alone.

Controversy exists regarding the extent to which age, menopausal status, and/or lifestyle behaviors account for the increased weight, fat mass, and central adiposity experienced by midlife women. To address this question, the authors longitudinally examined the relations of aging, menopausal status, and physical activity to weight and waist circumference in 3,064 racially/ethnically diverse wom...

Fifty fall-weaned heifers with initial weights of 209 kg (yr 1) and 222 kg (yr 2) were used to determine effects of lasalocid on weight gains, forage intake and ruminal fermentation of stocker cattle grazing winter wheat pasture. The heifers grazed a single wheat pasture for about 100 d each year, and were individually fed 1.06 kg of supplement (6 d/wk) pro-rated to supply 0, 100 or 200 mg lasa...

p olicy makers in housing sector seeks to use instruments by which they can control volatility of housing price and prevent high disturbances of the bubble and price shocks, or at least, reduce them. in the portfolio and speculation theories, it is emphasized that speculative demand for housing is the main cause of shocks and price volatilities in the sector. the theory of housing price bubble ...

A total of 133 observations on mean daily mass gains from 19 calves reared on either whole milk (control) or preserved colostrum (treatment) were estimated. The control group had a total of 104 observations computed, while the treatment group had a total of 29 observations. There was no significant difference in the overall mean daily mass gains between the treatment and control groups which we...

Three hundred seventy-seven male stocker calves were used to study the effects of three receiving diets, two growing-finishing diets and two levels of shipping shrink on compensatory gains during the post-receiving feeding period. Calves received on a 75% concentrate diet gained 19 kg more during the first 42 d than those received on hay plus .91 kg daily of protein supplement (P less than .01)...

The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...
