abstract surface water restriction and supply variation of these resources causes of over extraction of groundwater and unbalance between feed and extraction of groundwater in iran. agricultural sector as the biggest consumer of water resources has the most share of this unsustainability. this paper studies the conjunctive use of surface and groundwater in agronomy production in qazvin basin, o...

With such situations, it seems clear that a reduction of food wastage at global, regional, and national scales would have a substantial positive effect on natural and societal resources. Food wastage reduction would not only avoid pressure on scarce natural resources but also decrease the need to raise food production by 60 pe...

We hypothesized that feed resources could be deferred to a later time in the production cycle without a decrease in fertility or weight of calf produced in heifers and young cows. One-hundred and thirty-one MARC III (four breed composite: (1/4) Hereford, (1/4) Angus, (1/4) Red Poll, and (1/4) Pinzgauer) heifers were divided into three treatments: M-M-M-M (n = 46), L-H-M-M (n = 41), and L-L-L-H ...

Over the years, role and strength of dairy goat is increasing in Barani Tract of Punjab. The bread and butter needs of poor and small household are largely depends on livestock specifically on the dairy goats. The 80 percent livestock management activities are mostly depends upon women; therefore under the experimentation of feed supplementation mainly women's were included as research partners...

Most breeding programs have focused on improving economically relevant output traits such as growth, carcass quality and fertility to enhance the economic viability of beef production systems. Generally absent from current breeding programs in the U.S. are avenues for exploiting genetic variation in feed efficiency, even though reductions in feed inputs would substantially improve profitability...
