Effects of protection system and grazing seasons on goats’ nutrition in El Rosa, North Kordofan State, Sudan
Journal Title: Scientific Journal of Animal Science - Year 2012, Vol 1, Issue 5
Abstract
The range grazing and distance walked for diet selection and nutritive value were studied in close and open range systems at the flowering and seed setting stages during the September and November 2009 respectively in El-khuwei locality (El Rosa). A completely randomized design was used (CRD). Sampling was done by two stage flowering and seed sating stage under protected and open range systems were selected diets and feed intake locating a 2000 x 2000 m plots. The average weights gains during the flowering and seed setting stage were 23.25 and 26.82kg respectively. Goat preference on bite counts of the different species significantly higher (P < 0.001) at flowering stage ranked leflef Luffa aegyptiaca, Aborakhus Andropogon gayanus, Bano Ergrostis tremula, Difra Echinocloa colonum, Huskneet Cenchrus biflorus and Himeira Hymerocardia. Whil Gadgad Geigeria alata, Gaw Aristida sp, Umfraredo Schoenofeldia gracilis, Fisiya Fimbristyls hispidula and browses Usher Calotropis procera least than that. A significant higher (P < 0.001) goats selective feed intake, in vitro dry matter digestibility dry matter, organic matter and crude protein higher in the protecte range at flowering stage and lowers in the open range at seed setting stage. However; highly ash contents and crude fiber in the open range system during the seed satting stage and least than that. The distance walked by goats for diet search was significantly longest in the open range system during the seed setting stage. Body weight gain was significantly highest during the flowering stage. It was concluded that at flowering stage higher goats preference on bite counts of the different species and body weight gain. However; feed intake, in vitro dry matter digestibility dry matter, organic matter and crude protein in the protecte range. During the seed satting stage were higher ash contents, crude fiber and distance walked by goats for diet search in the open range system.
