Determination of Chemical composition, and degradability coefficients, ruminal- intestinal disappearance and digestion models of dry matter and protein species of halophytes (Kochia scoparia, Atriplex domorphostegia, Suaeda arcuata and Gamanthus gamocarpu

Samples of halophytes (Kochia, Atriplex, Suaeda and Gamanthus) were collected and analysed for chemical composition (CP, EE, GE, Ash, NDF, ADF, NPN, Ca, P, Na, K, CI, Mg, Fe, Cu and Se) using standard methods. in addition, degradability coefficients, ruminal - intestinal disappearance and digestion models of dry matter and protein of the samples were determined using in situ technique. The results indicated that the chemical composition of Kochia and Atriplex is more appropriate than Suaeda and Gamanthus. Nevertheless, all of the halophytes had high levels of Na, CI, Cu and Se. The halophytes contain low levels of Ca, P, K and Mg. quickly degradable coefficients of dry matter and crude protein of kochia was 0.31 and 0.35, Atriplex was 0.39 and 0.50, respectively. They were less than those of Suaeda and Gamantus. Gamanthus had the highest effective degradability of dry matter and crude protein. Ruminal dry matter and crude protein disappearance of Kochia and Atriplex were significantly less than that of Suaeda and Gamantus (P
