The aim of the present study was to determine the nutritive value of Alhaji camelorum plant using nylon bag and gas production techniques which compared with alfalfa hay. Fodder samples were hand harvested and its chemical and phenolic composition was determined according to standard laboratory methods. The methods of gas production, nylon bags and three-step enzymatic digestion were used to determine the nutritive value of the samples. The amount of organic matter, crude protein and Ca of Alhaji camelorum was lower than alfalfa hay (P<0.05). Wheras, the neutral detergent fiber, acid detergent fiber, lignin, ash and phosphorus content of Alhaji camelorum were significantly higher than alfalfa hay (P<0.05). The amount of total phenolic compounds, total tannin, condensed and hydrolyzable tannin of Alhaji camelorum was also higher than alfalfa hay (P<0.05). There was no significant difference between the fast degradable, slow degradable and degradablity rates of Alhaji camelorum and alfalfa hay. However, the effective degradability of Alhaji camelorum was lower than alfalfa hay (P<0.05). Gas production rate (c) of Alhaji camelorum and alfalfa was similar, however, its gas production potential (b) was lower than alfalfa hay (P<0.05). Organic matter digestibility, metabolizable energy, and net energy for lactation were also estimated to be lower in Alhaji camelorum than alfalfa hay (P<0.05). According to the results of the present research, Alhaji camelorum plant with appropriate nutritional caractristics and digestibility parameters along with its lower production cost compare to alfalfa hay, can be replaced with a part of the forage of camel diet.

In the present study, the chemical composition and nutritional value of quinoa crop residues were determined using insitu and invitro gas production techniques in comparison with alfalfa hay. After harvesting, whole quinoa plants were dried at environmental temperature, the seeds were separated, and the crop residues were used for the experiment. The results showed that the content of gross energy, dry matter, organic matter, neutral detergent fiber and lignin of quinoa was higher than alfalfa hay (P<0.05). Crude protein concentration of quinoa (12.29%) was lower than alfalfa hay (14.32%). The main part of the tannin in quinoa was hydrolysable. Although the degradation rate and post-ruminal digestibility of quinoa and alfalfa hay were similar, ruminal, and total tract digestibility of quinoa were lower than alfalfa hay (P<0.05). No significant differences were found in gas production rate (c) between quinoa and alfalfa hay, however, it’s gas production potential (b) was lower than alfalfa hay (P<0.05). Organic matter digestibility, metabolizable energy and net energy of lactation in quinoa crop residues were also lower than alfalfa hay (P<0.05). Based on the results of this study, quinoa crop residues have suitable nutritional potential for replacing part of the forage to meet part of the nutritional requirements of ruminant feeds. However, invivo studies are recommended to determine it’s appropriate level in the diet.
