We conducted two experiments to evaluate the effects of corn supplementation, source of corn, and corn particle size on performance and nutrient utilization of lactating dairy cows. In experiment 1, treatments were 1) direct-cut grass-legume forage without supplement, 2) direct-cut forage plus 10 kg DM of ground dry shelled corn-based concentrate, and 3) direct-cut forage plus 10 kg DM of coars...

A diversity of forage species and forage ecosystems suited to different management practices exists in the United States. The future of cultivar development in forages includes the new and evolving areas of genomic and transgenic technologies. Genomic research gained momentum with the publication of the complete DNA sequence of the human genome and has since expanded to plant species including ...

The influence of environmental factors on forage quality of temperate and tropical grasses has been reviewed by several authors, who summarized how light, temperature, drought and soil nutrients influence chemical composition, and digestibility of forages grown in contrasting areas of the world. The effects of season of the year on forage growth, grazing behavior and animal performance have als...

Sheep and cattle farmers need pastoral systems that are more productive and environmentally sustainable. The role that high feeding value herb and legume forage species can play in the farms of the future is highlighted. It is shown that species such as chicory (Cichorium intybus), plantain (Plantago lanceolata), red clover (Trifolium pratense) and white clover (T.repens) can provide live weigh...

Red clover ( L.) is a cool-season forage legume grown throughout the northeastern United States and is the most widely planted forage legume after alfalfa ( L.). Red clover provides high-value feed to the livestock because of high protein content and easy digestibility. To date, genomic resources for red clover are scarce. In the current study, a de novo transcriptome assembly of red clover was...

CNPSo 1112(T) is a nitrogen-fixing symbiont of perennial soybean, a tropical legume forage. Its draft genome indicates a large genome with a circular chromosome and 9,554 coding sequences (CDSs). Operons of nodulation, nitrogen fixation, and uptake hydrogenase were present in the symbiotic island, and the genome encompasses several CDSs of stress tolerance.

We report here the complete genome sequence of Mesorhizobium ciceri bv. biserrulae strain WSM1497, the efficient nitrogen-fixing microsymbiont and commercial inoculant in Australia of the forage legume Biserrula pelecinus The genome consists of 7.2 Mb distributed across a single chromosome (6.67 Mb) and a single plasmid (0.53 Mb).

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...

A 2-yr study was conducted to confirm that managed pastures can provide Holstein steers adequate P to meet their daily requirement. Treatments offered were trace mineralized salt with or without additional P. In the first year, 80 Holstein steers (248 kg of BW) were assigned to 4 grazing groups. Treatments were trace mineralized salt only or a 67:33 mixture of trace mineralized salt and dicalci...
