What causes hepatogenous photosensitization syndrome in cattle?
This toxicity is caused by the presence, in the bile ducts and liver, of crystals of insoluble salts of sapogenin glucuronides originating from steroidal saponins present in signal grass. The sapogenin content varies in the same Brachiaria species, due to environmental stress, plant age and the stage of growth. Animals develop skin lesions, facial oedema, liver damage and rumen stasis that result in severe drops in weight gain (down to 40%) and in some cases death (17% of cases) if the animals are not removed from the pasture ( Gracindo et al., 2014; Fagliari et al., 2003 ). The disease occurs within the first 30 days after grazing signal grass or until 60 to 90 days after ( Riet-Correa et al., 2011 ). Outbreaks of Brachiaria spp. poisoning in central Western Brazil are frequently observed in pastures left ungrazed for more than 30 days. They also occur during the growing stage of the pasture at the onset of the rainy season ( Brum et al., 2009 ).

Some varieties are much more productive than others, and different types of cattle-raising operations, such as dairy farms, might benefit more from specific varieties.

What is the best grass for cows?
Warm-season perennial pastures tend to be the best grasses for a cow-calf operation because they do not have to be planted each year. Once established, these pastures continue to produce for many years. The annual grasses are the most expensive grasses for forage because they must be planted each year, the seed is costly, there is a limited production season and they require high rates of fertilizer.
What is the role of grass in livestock?
Warm-seasoned annual grasses, such as the sudans or forage sorghums, play definite roles in livestock production. Being annual plants, they are expensive because land must be prepared and seeded annually. They offer higher quality (digestibility) grazing than perennial warm-season plants, but their production period is shorter. They use less fertilizer, will serve as temporary pasture and maintain a relatively high carrying capacity of two or three animals per acre for 30- to 45-day periods. Their prime role in forage production, however, is for high quality hay.
What are the different types of forage for beef cattle?
Pasture forages for beef cattle can be roughly divided into five categories—warm-season perennials, warm-season annuals, cool-season perennials, cool-season annuals and legumes for pastures. Each of these forage types can meet the nutritional requirements of beef cattle when they are at their peak production (Figure 1).
What are legumes used for?
They can be over- seeded into permanent pastures or seeded with winter annual pastures. Legumes have the unique ability to fix their own nitrogen if they are properly inoculated (nitrogen-fixing bacteria is added to the legume seed before planting). They require high levels of phosphorus, potassium and, in acid soil, lime. Cool-season or temperate legumes produce most of their growth during the late winter-spring period, when they are very useful in beef cattle operations. Warm-season or tropical legumes, such as cowpea, soybean, and peanut, can provide high quality forage during the summer. However, they are used as a salvage crop in drought years when they do not “yield” well as a row-crop.
What is the problem with overseeded pasture?
The problem is competition in late spring between an overseeded pasture and a warm season perennial pasture that is beginning to grow.

Their prime role in forage production, however, is for high quality hay.
How can livestock producers benefit from forage?
Consequently, livestock producers can benefit by combining two or more forage plants into a forage system. By growing adapted summer and winter forage species, livestock producers can furnish grazing for most of the year. Although this requires management and planning, it reduces hay and feed costs.
Why are wet grasses not good for cattle?
