The low digestibility of fiber in alfalfa (Medicago sativa L.) limits dry matter intake and energy availability ruminant animal production systems. Previously, plants were identified for or high rapid (16 h) potential (96 vitro neutral detergent (IVNDFD) plant stems. Here, two cycles bidirectional selection 16 h 96 IVNDFD carried out. resulting populations evaluated total herbage, percentage st...

three grass species, agropyron desertorum (agde) and agropyron elongatum (agel) and recently, bromus tomentellus (brto) are mainly used for range improvement as mixed seeding in semi-arid areas of iran. because there is little information about management of these grasses, this study was conducted at the sisab research station in northern iran to evaluate their responses to grazing management a...

1. The fatty acids of the triacylglycerols of subcutaneous adipose tissue of cattle, sheep, goats and red deer (Cervus elaphus) which consumed either herbage or a barley-rich diet were analysed for their content of branched-chain components. 2. Whereas the consumption of the barley-rich diet by sheep and goats was associated with the occurrence of relatively high proportions of branched-chain f...

High cost of synthetic fertilizers and their hazardous effects catapult the exploration alternative nutrient formulations soil amendments. This study aimed to synthesize a novel biochar-mineral-complex (BMC), evaluate its supplying improvement performances. In hydrothermal reaction, BMC was prepared using biochar derived from distillation waste Lemongrass (Cymbopogon flexuosus) farmyard manure,...

Land consolidation changes the land use types and then the biomass. The measure and calculation of biomass fore-and-aft land consolidation worked out by the sample plot method in terms of arbor, shrub, herbage plants and crop. The result shows that the biomass is increased 580 t after land consolidation, meaning the impression of land consolidation is remarkable in general. The results of monom...

Fluorine is one of the most abundant elements in the environment. Animals are exposed to the ionic form of the element (fluoride) which may be present in feed materials and drinking water. Moreover, ingestions of feed materials contaminated with soil for examples by ruminants and horses contribute to exposure in geographic areas with high natural fluorine concentrations, as the average concentr...

What is the future for livestock agriculture in the world? Consumers have concerns about sustainability but many widely used livestock production methods do not satisfy consumers' requirements for a sustainable system. However, production can be sustainable, occurring in environments that: supply the needs of the animals resulting in good welfare, allow coexistence with a wide diversity of orga...
