abstract shortage and improper distribution of rainfall in tea growing period are important growth limiting factors in tea fields in northern part of iran. if there is not any other limited factors, supplemental irrigation by sprinkler can increase tea yield. this study was carried out in order to investigate the optimum sprinkler irrigation interval on yield and water use efficiency of tea. th...

BACKGROUND Synoptic circulation patterns (large-scale tropospheric motion systems) affect air pollution and, potentially, air-pollution-morbidity associations. We evaluated the effect of synoptic circulation patterns (air masses) on the association between ozone and hospital admissions for asthma and myocardial infarction (MI) among adults in North Carolina. METHODS Daily surface meteorology ...

sixty eight holstein cows, 38 primiparous and 30 multiparous ones, were employed in a randomized complete block design, blocked to evaluate the effects of 2 diets in various ruminal fermentable carbohydrate sources (ground corn vs rolled wheat) on rumen fermentation and performance during preparturient period. primiparous and multiparous cows were blocked by parity. the cows were fed diets as t...

Accepted: 21/05/2015 Abstract The present study was aimed to investigate liver function upon supplementation of vitamin E to dry Murrah buffaloes through analysis of serum enzymes. The Murrah buffaloes (n = 12) were selected during their late gestation from National Dairy Research Institute (NDRI) livestock herd and divided randomly into two groups, comprising of six each. Buffaloes of group I ...

Since the initial report in 1978 of galactopoietic effects of a photoperiod of 16 h of light:8 h of darkness, numerous studies have confirmed long-day stimulation of milk yield. The endocrine factor(s) responsible for increased milk yield, however, has eluded identification. Recent studies suggest that insulin-like growth factor-I (IGF-I) may mediate the galactopoietic response to long day phot...

OBJECTIVES Dry socket may occur secondary to the removal of any tooth. However, most dry socket cases develop in the third molar region. Dry socket is multifactorial in nature and has been treated using various modalities with varying success rates. This study assessed the efficacy of platelet rich fibrin (PRF) in established dry socket. MATERIALS AND METHODS Ten patients of either sex aged f...

The objectives of this research were to characterize dry period lengths for US Jerseys, determine the effects of days dry (DD) on subsequent lactation actual milk, fat, and protein yields, fat and protein percentages, somatic cell score (SCS), and days open (DO), and to determine the dry period length that maximizes yield across lactations. Field data, collected through the Dairy Herd Improveme...

The objective was to utilize data from modern US dairy cattle to determine the effect of days dry on fat and protein yield, fat and protein percentages, days open, and somatic cell score in the subsequent lactation. Field data collected through the dairy herd improvement association from January 1997 to December 2003 and extracted from the Animal Improvement Programs Laboratory national databas...
