The production of luteal oxytocin in ewes, resulting from the intrajugular injection of 200 micrograms of PGF2 alpha, could be determined by the increase in intramammary pressure. This simple indirect method of measuring the activity of the corpus luteum enabled easy detection of renewed post-partum ovulation or the onset of pregnancy. The response was monitored every two days between Days 0 an...

We consider a budget-constrained mechanism designer who selects an optimal set of projects to maximize her utility. A project’s cost is private information and its value for the designer may vary. In this allocation problem, the selection of projects both which and how many is endogenously determined by the mechanism. The designer faces ex-post constraints: The participation and budget constrai...

Changes in programming of neonatal immune development were effected through maternal immune modulation (Leishmania major inoculation). In progeny of these dams, immune profiles in both blood and spleen were changed throughout the neonatal period and were pronounced after weaning. White blood cell (WBC) and lymphocyte counts in blood of 45-day-old progeny were two-fold less than control animals....

Developing Böhm-Bawerk’s (1914) Macht oder ökonomisches Ge-setz, we characterize the different intervention modalities as coercive «fixing» of prices, goods (quantities or modes performing) persons, also with their effects. Given that subjective but real forces underlying market processes respond effects which are opposite to those pursued, «intervener» controller would be induced an in crescen...

The common practice of artificially rearing lambs from prolific meat breeds sheep constitutes a welfare issue due to increased mortality rates and negative health issues. In this multidisciplinary study, we investigated the possible short- mid-term advantages feeding fresh ewe's milk instead commercial replacer on lambs' growth, welfare. Romane were either separated their mothers D3 fed with La...

The pre-weaning period is crucial for rumen developmental plasticity, which can have a long-term impact on animal performance. Understanding the rumen microbiota during early life is important to elucidate its potential role in rumen development. In this study, the rumen microbiota of 10-day-old Hu lambs fed either milk replacer (B10), milk replacer and starter (STA) or milk replacer and starte...

due to contiguous city of ravar with lut and dasht-e kavir desert, and weather conditions, water is one of the rarest agricultural inputs in this city. pistachio allocates 90% of garden and 73% of agricultural lands of the city and it is the most important agricultural product in this region. a major source of agricultural water supply in this area is groundwater. low price of water on one side...
