Abstract

Fodder trees are grown in Nepal from time immemorial. A variety of fodder trees exist in various parts of the country, from lowland Terai to the high hlls. It has been reported that the total production from fodder trees accounts for about 15% TDN requirement in the country. It is estimated that 0.3 million tones of TDN is supplied by tree fodders in the hills. The nutritive values of fodder tree are not still evaluated well, even if evaluated, the results are not consistent. Altogether 802 samples of different fodder tree species were collected from Baitadi, Darchula, Dhankuta, Dolkha, Dadeldhura, Dhading, Gorakha, Illam, Jhapa, Kailali, Kaski, Kavre, Lalitpur, Larnjung, Makwanpur, Mustang, Nawal Parasi, Palpa, Rupendedeh, Rasuwa, Sankhuwasava, Sindhupalchok, Solukhumbu, Surkhet, Syangja and Tanahun districts of Nepal during past 12 years and were evaluated for their nutrient content.Average dry matter, organic matter, total ash and crude protein content of different fodder trees were found to be 32.62,88.67,11.33 and 14.70 percent respectively. Similarly, average neutral detergent fibre (NDF), acid detergent l'ilve (ADF), lignin, hemicellulose and cellulose content of different fodder trees were recorded 49.30,41.73,19.29, 7.50 and 22.5 1 percent respectively. Likewise, average calcium and phosphorous content was noted 2.20 and 0.24 percent respectively. Highest content of dry matter (45.97%), organic matter (97.96%), total ash (26.63%) and crude protein (29.03%) was recorded for Malbans, Jangal Jilebi, Batuke and Rajbrikchhya respectively. Likewise,Nimbans had highest NDF and hemicellulose content (74.99 and 35.89% respectively). Highest content of ADF (63.371(), lignin (44.91%) and cellulose (42.10%) was observed in Voldung, Batuke and Siris (whlte) respectively.In term of nuneral Kamle was found to be superior in calcium content (5.31%) and Tale in phosphorous content (0.55%) as compared to other fodder trees.
