Guar (Gyamopsis tetragonoloba) is annual drought - resistant leguminous plant which is grown up mainly in India and Pakistan.
This plant is generally grown up for the sake of guar pitch which has broad food and industrial application. The guar forage is the key side product of production of guar pitch with protein content from about 380 g/kg.
The guar forage can be both in the form of powder (CHURI), and in the granulated look (KORMA) and represents seed mixture and peel in the ratio of about 25% to 75% respectively. The guar forage is protein - rich also carbohydrates, 100% are natural product without addition of any chemicals and preservatives, and also do not contain GMO. Guar is high - protein forage which maintenance makes from 40 to 60% depending on type of forage.
The guar forage also contains chemical compounds, the called saponins which content varies from 5 to 13% on a. s. v. and which value consists antibacterial, antifungal and anti - protozoan action.
High contents of amino acids in protein of guar forage does it by useful protein additive for broilers and laying hens. As the guar forage contains protein, proteins, methionine and phosphorus is more, than soy meal, partial replacement (
Nevertheless, some anti - nutrients (trypsin inhibitors, the pitch remains, saponins) which are present at guar forage limit its use in large numbers in forages of bird. Harmful effects of inhibitors of trypsin, raise certain doubts as during researches it was established that the guar forage contains their smaller quantity, than soy meal. Thus, growth inhibition which follows addition of guar forage in diet of birds can be connected with residual content of pitches in it. Pitch, because of the sticky nature, increases intestinal viscosity and reduces nutritive absorption from small intestine. One of methods for improvement of negative effects of contents in guar forage of galaktomannan - addition of enzymes beta mannaz. As a result viscosity of guar pitch in stern decreases that increases comprehensibility of starch, improves metabolizable energy of guar forage and, respectively, improves growth indicators at broilers.
When feeding KRS guar positively influences digestibility of forages at cows, increases fat content of milk, and also its quantity. The guar forage can join in composition of compound feeds or separately be used.
At inclusion of 5% of guar forage in diets of milk cows the problems connected with its palatability, however when feeding the forages containing 10 - 15% of guar were noted, cows got used to its smell and taste in several days and in spite of the fact that potrebelny such forage decreased a little, in comparison with basic, the yield of milk remained the same.
As for feeding of meat cattle, when feeding 2, 3 kg of guar forage on one animal a day in mix with other sterns of problems with its consumption it was not observed. Also, problems with consumption of guar forage in quantity to 50% of the gross weight of forage were not observed when its percentage in diet was increased gradually. So, during researches the gain of calfs at daily feeding 2, 3kg guar forage and cotton meal (in combination with full feeding by silo) made 154 and 155 kg respectively during the 150 - day period of cultivation. Similar results were received also during fattening.
