A first limitation of the nutritive value of mature Chloris gayana hay is its low intake by livestock when compared to hays of other tropical grass species. However, after the second cut, the effect of the stage of maturity on intake and in vivo digestibility was less important as these parameters remained high even with mature forage (Mbwile et al., 1997b). Rhodes grass is a perennial or annual tropical grass. Sci., Plants poisonous to livestock. Another limitation of mature Rhodes grass hay is its low protein content, particularly during the dry season. Drought tolerant, Rhodes grass grows in areas where rainfall ranges from 23 to 63 inches annually. In: Kategile, J. In order to optimize the harvested biomass, Rhodes grass hay is generally harvested at an advanced maturity stage. Anim. Rhodes grass hay was then able to meet sheep maintenance requirements (x 1.1-1.2) (Mero et al., 1998). There are other practical uses that farmers can benefit from when growing Chloris gayana. pap., Samaru (Nigeria), No. If the grass is used to make hay, cuttings can be done once a month (Göhl, 1982). Rhodes grass as fresh forage or hay can be safely used in rabbit feeding but only as a fibre source, as shown by the following trials. Stn, 77-80. In Tanzania, goats fed a low protein Chloris gayana hay (5.7-7.7% DM) were supplemented with concentrates containing between 10-18% DM protein. The fruit is a caryopsis, longitudinally grooved (FAO, 2014; Quattrocchi, 2006; Moore, 2006; Cook et al., 2005; Duke, 1983). Grassland Index. Studies at and in association with the Rowett Research Organization, Bucksburn, Aberdeen, UK. Effects of inoculation with lactic acid bacteria on the bacterial communities of Italian ryegrass, whole crop maize, guinea grass and rhodes grass silages. There are various genetic varieties of Chloris gayana that exist like Katambora, Pioneer and Callide. Ecocrop database. Misc. Prostrate cultivars are suitable for grazing and erect cultivars are adapted to hay (FAO, 2014; Quattrocchi, 2006; Cook et al., 2005; Duke, 1983; Göhl, 1982). The culms are tufted or creeping, erect or decumbent, sometimes rooting from the nodes. However, its nutritive value strongly decreases with maturity, especially after the first cut. It is likely that the tissue structure of the stems and leaf sheaths of both tropical grasses makes inner cells relatively inaccessible to the rumen micro-organisms (Wilman et al., 1998). Hay harvested at a later stage of maturity has a low protein content and a high fibre content, particularly in the stems, and it should be supplemented when fed to ruminants with nutritional requirements higher than those necessary for maintenance. Chloris gayana is a hardy, evergreen very leafy tufted perennial grass. As soon as favourable conditions occur in early spring, the grass resumes active growth and it provides full groundcover within 3 months of sowing (NSWDPI, 2004). Rhodes grass, abyssinian Rhodes grass, Callide Rhodes grass, common Rhodes grass [English]; chloris, herbe de Rhodes [French]; capim de Rhodes [Portuguese]; grama de Rodas, pasto de Rodas, pasto Rhodes, zacate gordura [Spanish]; rhodesgras [Afrikaans]; koro-korosan [Philippines/Tagalog]; banuko [Philippines/Ilokano]; 非洲虎尾草 [Chinese]; アフリカヒゲシバ [Japanese]. In Kenya, intake of Rhodes grass decreased with maturity in grazing growing Friesian and Ayshire heifers (Abate et al., 1981). Symposium sur l'alimentation des ruminants en milieu tropical (du 02/06/1987 au 06/06/1987; Pointe-a-Pitre (FRA)) INRA, Barry, G. A., 1984. J. Japan. A., 1988. Agric. Some grass species in these habitats include red oat grass (Themeda triandra) and Rhodes grass (Chloris gayana) in tropical savannas, and purple needlegrass (Nassella pulchra) and galleta in temperate areas. CRC Press, Taylor and Francis Group, Boca Raton, USA, Raharjo, Y.; Cheeke, P. R.; Patton, N. M.; Supriyati, K., 1986. II. However, the evolution of milk production during the experiment was not reported, although the cows produced 8.7 kg milk/d at the beginning of the experiment (Mbwile et al., 1997b). Field evaluation of seven grasses for use in the revegetation of lands disturbed by coal mining in Central Queensland. [9] In addition to this, "growing cultivated forages, in association with food crops, can contribute to the improvement of the qualitative and quantitative supply of livestock feed. Due to its deep roots, Rhodes grass can withstand long dry periods (over 6 months) and up to 15 days of flooding (FAO, 2014; Cook et al., 2005). Effect of ammonia treatment on chemical composition and dry matter digestibility. Supplementation, when forage is of low quality, was recommended in order to sustain an average daily gain of 550 g/d (Abate et al., 1981). Sci., 47 (1): 35-37, Todd, J. R., 1956. Bull. Hawaii, CTAHR Ext. Cornell Univ., Dept. Rhodes grass is generally harvested for hay at a late stage of maturity, when the protein content is low, in the 5-8% DM range (Mtenga et al., 1990). It also reduced NDF content. In Australia, Chloris gayana fed at a late stage of maturity was fed to lactating cows of moderate yield, generally with supplementation. In Australia, it was introduced by soldiers returning from the Boer wars at the beginning of the 20th century. However, seleniferous plants are not readily eaten by most animals due to their bitter taste and strong odour, and tend to be consumed only when other forage is sparse (Cornell University, 2014). Soc. It is tolerant of Li but not of Mn and Mg (Cook et al., 2005). Pioneer has been superseded by Katambora. Sci., 17 (3): 233-242, Quattrocchi, U., 2006. J., 8 (3): 126-132, Göhl, B., 1982. Central Research Station, Mazabuka, N. Rhodesia, Work, S. H., 1937. [4] Its ideal soil would be anything greater than a 4.3 pH level in terms of acidity. Anim. [7]:1574 Since Chloris gayana shows good salt tolerance, this type of grass can be beneficial to farmers who have salinity problems in their soil. Grassl. Anim. Valenzuela, H., Smith, J. It is also cultivated in some areas as a palatable graze for animals and a groundcover to reduce erosion and quickly revegetate denuded soil. Rhodes grass (Chloris gayana). Chloris gayana can be very helpful to farmers and NGOs in terms of sustainable agricultural development. A different type of Chloris gayana are tetraploid types. Each spikelet in the raceme is a few millimeters long and contains one or two fertile florets and up to four sterile florets. Cattle liveweight gains. For vegetative propagation, larger clumps can be cut into pieces and planted at 1 m distance from each other (NSWDPI, 2004). Rhodes grass (Chloris gayana Kunth) is an important tropical grass widespread in tropical and subtropical countries. Sugar cane products as potential energy supplements for cattle fed low quality roughage. E. Afr. [5]:2 In addition to this, Chloris gayana has a moderate aluminum tolerance. The nutritive value is also influenced by the season (Mbwile et al., 1997a) and variety (Mero et al., 1997; Milford et al., 1968). Rhodes grass is a forage of highly variable composition. In Kenya, dairy heifers grazing Rhodes grass had an average daily gain of 581 g/day during a one year experiment with a stocking rate of 2 livestock unit/ha, but the pattern of gain ranged between 200 and 1100 g/d according to the period of the year. For. The seed germinates quickly (1–7 days) depending on temperature. Evaluation of tropical forages and by-products feeds for rabbit production : 1. [4] This too is important for being able to use this type of grass efficiently. Rhodes grass hay cut early (21 days of regrowth) had a high nutritive value, comparable to that of fresh Rhodes grass (Tagari et al., 1977). Suttie, J.M., (2000), Hay and Straw Conservation - for small scale farming and pastoral conditions: chapter V: hay crops - cereals and grasses, Food and Agricultural Organization of the United Nations. Plant morphological characteristics and resistance to simulated trampling. Chloris gayana is a leafy short-lived perennial grass that grows in wet areas and flowers during summer.

CSIRO, DPI&F(Qld), CIAT and ILRI, Brisbane, Australia, Cornell University, 2014. Duke, J. Chloris gayana originated from Africa and is now widespread in tropical and subtropical areas worldwide. Agric., 39 (3): 307-316, Holm, J., 1971. In Australia, with Friesian-Holstein heifers, a comparison of Rhodes grass cut at two stages of maturity (60 and 100 days) and treated with CaO, NaOH or a microbial inoculant before ensiling found that only NaOH treatment allowed a 25% increase of DM intake for mature grass silage and increased its in sacco digestibility. Feed resources in Ethiopia. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species. Feed Sci. Revista da Faculdade de Medicina Veterinaria e Zootecnia da Universidade de Sao Paulo, 19 (2): 167-172, Lucci, CS. Chloris gayana can be a good option for a farmer when it comes to trying to solve these problems. Trop. Potential of the indigenous desert grasses of the Arabian Peninsula for forage production in a water-scarce region. It is grazed, cut for hay or used as deferred feed but it is not suitable for silage. In a follow-up study, with Holstein-Friesian dairy cows grazing irrigated Rhodes grass pastures (6-week grazing rotation), supplemented with 5 kg of cereal-based concentrate, increasing the stocking rate from 3.5 to 6.1 cows/ha had no effect on milk production. Mengistu, A., 1985. 1982, 104. Ensiling of Rhodes grass has been little studied, since it is difficult to ensile due to its high moisture coupled with low contents of water-soluble carbohydrates, similar to other tropical grasses (Parvin et al., 2010). Intake of tropical grass, legume and legume-grass mixtures by rabbits. In Australia, aerial seeding is frequent (FAO, 2014; Cook et al., 2005).

FAO, Division de Production et Santé Animale, Roma, Italy, Haffar, I. ; Alhadrami, G., 1997. Personal communication. Chloris gayana can be vegetatively propagated or established from seeds. In terms of grass species, this type appears to be one of "the most salt-tolerant species"[7]:1583 in terms of grasses. Les aliments du bétail sous les tropiques. Because Rhodes grass seeds are fluffy, they may need to be coated or mixed with a carrier to improve the flow through the seeder (Moore, 2006). Rhodes grass is known to be a selenium accumulator, and, when grown on selenium-rich soils, its selenium content can cause mortality or morbidity in livestock (NSWDPI, 2004). A.; Said, A. N.; Dzowela, B. H. Dairy cows grazing irrigated Rhodes grass pasture (2 to 6 weeks regrowth, after the 2nd or 3rd cut) mulched at least once a year produced more than 14.3 kg/d of milk when supplemented with 5 kg of cereal-based concentrate per cow at a stocking rate up to 3.7 cows/ha (Ehrlich et al., 2003a). During the first year of cultivation, livestock should not enter the stand until the secondary root system, which allows grass anchorage in the soil, is well established, otherwise the livestock might uproot the grass and damage the stand. Proceedings of the Australian Society of Animal Production. Seasonal variation in the chemical composition of the grasses, Valenzuela, H. ; Smith, J., 2002. Chloris gayana is characterized by the particularly low nutritive value of the stems compared to the leaves (Mbwile et al., 1997a; Mero et al., 1997; Milford et al., 1968). CRC World dictionary of grasses: common names, scientific names, eponyms, synonyms, and etymology. "[9] A possible solution to this would be to intercrop Chloris gayana with food crops. Rep. Hawaii agric. Univ. In Australia, it has been mixed with butterfly pea (Clitoria ternatea) for revegetation purpose (Cook et al., 2005).
