Historical traces of organisms on the seafloor, such as shells and tubes, constitute ecological memory ancient benthic assemblages serve an important resource for understanding assembly modern communities. Archeological shipwrecks are particularly interesting submerged substrata both their archeological biological implications. For first time, we studied species composition life-history traits ...

This paper examined the relationship existing between scrotal morphometric characteristics and reproductive potentials of rams. Reproductive organs have essential roles in the reproduction of species. Reproductive efficiency and increased production can only be achieved by understanding the morphometric characteristics of these very important and sensitive organs of reproduction. Sperm producti...

Water stress is one of the major environmental stresses causing growth retardation and yield loss of plants. In the past decades, osmotic adjustment, antioxidant protection, and stomatal movement have been extensively studied, but much less attention has been paid to the study of root system reprogramming to maximize water absorption and survival under water stress. Here, it is shown that polye...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

Background Gametes for breeding high-value livestock is commonly preserved in gene banks for later use in assisted reproduction programs. Such material can be used in artificial insemination or embryos transfer in the field as well as embryos in vitro production [1]. However, when these animals die, genetic material may be lost if it is not possible to recover and preserve spermatozoa from epid...

This study analyzed the economics of feeding dried poultry droppings as supplement in ram production. Gross margin analysis and profitability ratio was used to analyze the data collected. The result of the budgetary analysis revealed that highest total cost of ₦5292.98/ram was incurred, highest total revenue of ₦7565.40/ram, highest gross margin of ₦3272.41/ram and highest net farm income of ₦2...
