Abstract
The study was conducted to evaluate the effect of incorporation of dried and green date palm (Phoenix dactylifera) leaves in total mixed ration (TMR) comprising of 30:70 concentrates: Jowar hay as maintenance ration of adult Marwari sheep. Based on the in vitro studies and availability of air-dried date palm leaves (ADPL) and green date palm leaves (GDPL), the date palm leaves replaced 40% of jowar hay in total mixed ration. From each treatment groups four adult Marwari sheep (30-35 kg B.W.) were of similar age (26-30 months) and uniform conformation were selected and fed as per ICAR (1998) standard to meet their nutrient needs as donor of rumen inoculum for rumen fermentation pattern. Rumen liquor was collected at 0,2,4 and 6 h post feeding through a stomach tube against negative pressure created by a suction pump The energy and protein requirements of sheep were met as per ICAR (1998) standards. The treatments were, TMR without Date palm leaves (T1); TMR with ADPL replacing 40% of jowar hay (T2) and TMR with GDPL replacing 40% of jowar hay on dry matter equivalent basis (T3). The average values of T1, T2, and T3 groups for rumen parameters were pH (6.75, 6.64 and 6.98); Total nitrogen (92.74, 92.80 and 92.31 mg/dl); Non-protein nitrogen (13.03, 13.01 and 13.20 mg/dl); Soluble nitrogen (68.47, 68.73 and 68.87 mg/dl); Ammonia-N (10.96, 11.20, 11.16 mg/dl) and Total volatile fatty acids (12.34, 12.40 and 12.57 mM/dl). These treatment groups did not differ significantly.
KEY WORD: Dried Date Palm (Phoenix dactylifera L.), leaves, in vivo, marwari sheep.
