Abstract
The aim of the research is to determine the amount and nutritional value of pasture forage eaten by dromedary camels on saltwort pastures. As the results of the experiments showed, adult female camels consumed, on average, over three years, 19.2 kg of sagebrush-saltwort-herb pasture pasture food of the above-described saltwort pasture with an initial moisture content of 35.7% and a nutritional value of 0.44 feed units, 4.96 MJ of exchange energy , 50 g digestible protein, 2.92 g calcium, 0.73 g phosphorus and 27 mg carotene in 1 kg of pasture feed at natural moisture. Adult single female camels with live weight in the range of 530-550 kg in the indicated amount of pasture forage (19.2 kg) consumed an average of 12.29 kg of dry matter, which contained 8.45 forage units, 95.23 MJ of metabolizable energy, 960 g of digestible protein, 56.06 g of calcium, 14.01 g of phosphorus and 518.4 mg of carotene. The actual provision in digestible protein was 115.8%, as they consume 960 g at a rate of 829 g, which indicates good grazing and forage conditions of saltwort pastures. The indicated feeding level of single female camels provided the animals with the average daily gain of 670 g. On a similar type of saltwort pastures, a 1.5 year old young camel stock with an average live weight of 265 kg consumed about 11.5 kg of pasture forage, which contained 7.36 kg of dry matter, 5.06 forage units, 57.04 MJ of metabolizable energy , 575 g of digestible protein, 33.6 g of calcium, 8.4 g of phosphorus, and 310 mg of carotene. At the same time, the average daily gain of the experimental young stock for the grazing period is 620 g.
