Using a deterministic model for dairy herd according to milk pricing system in Iran, the economic weights of milk production, fat percentage, protein percentage and herd life with minimized cost were identified, while restricted total input and total costs were variable in animal unit. By data simulation and the data obtained from 3 different dairy herds in Iran, the sensitivity of economic val...

It is critical for managers to understand the basic fundamental differences of managing introduced and rangeland forages. In the eastern part of Texas, introduced species dominate forage-based livestock production systems. As you move west of the IH35 corridor from Denton to San Antonio and then west of IH37 from San Antonio to Corpus Christi, however, you will notice few introduced species are...

sainfoin (onobrychis sativa), a forage legume, is worth attention because of its production and superior quality among pasture and hay forage crops in iran. sainfoin forage yield may be reduced by different levels of salinity. increasing forage yield in saline environments through plant breeding could partially compensate for this shortcoming if sufficient genetic diversity and heritability be ...

Forage production is primarily limited by weather conditions under dryland production systems in Brazilian semi-arid regions, therefore sowing at the appropriate time is critical. The objectives of this study were to evaluate the CSM-CERES-Pearl Millet model from the DSSAT software suite for its ability to simulate growth, development, and forage accumulation of pearl millet [Pennisetum glaucum...

This study investigated the performance of steers grazing rhizomatous birdsfoot trefoil (Lotus corniculatus L.) (RBFT) compared to nonrhizomatous birdsfoot trefoil (BFT) in pure stands or when interseeded with endophyte-free tall fescue (Festuca arundinacea Schreb.; TF). Five forage treatments of RBFT, BFT, TF, RBFT+TF, and BFT+TF (four replicate paddocks per treatment) were continuously stocke...

VASILEVA, V., E. VASILEV and R. TZONEV, 2016. Subterranean clover (Trifolium subterraneum L.) as a promising forage species in Bulgaria. Bulg. J. Agric. Sci., 22: 222–227 The paper presents an overview of the possibility to use the subterranean clover (Trifolium subterraneum L.) (an annual leguminous self-seeding species, widespread component in the pastures of the temperate areas of Central an...

Reuse of saline drainage waters is a management option that has been suggested for the San Joaquin Valley (SJV) of California in order to reduce both the area affected by shallow water tables and the volume of drainage effluent requiring disposal. Salt-tolerant forages may play an important role in this strategy, while at the same time producing a food source for sheep and cattle. Crop selectio...
