“…Generally, as cell wall (fibre) increases, digestibility and energy content decrease (Van Soest, 1994). Our results were in line with those reported by Mahgoub et al (2005), Genin et al (2004) and Dayani et al (2012), who observed higher digestibility of date pulp with lower cell-wall content.…”

“…Al-Juhaimi et al (2012) found crude protein concentration in date pits from the date cultivar Barchi could reach 5.47%. This result for protein concentration is also similar to the reports of Hamada et al (2002), Ibrahim (2009), andDayani et al (2012). Also, as shown in Table 2, protein concentration in date pits differs across cultivars.…”

Date Pits: Chemical Composition, Nutritional and Medicinal Values, Utilization

et al. 2014

Date (Phoenix dactylifera L.) pits, by‐products of date fruit processing industries, can provide many essential nutrients and potential health benefits to the human body. The chemical composition of date pits includes dietary fiber, fat, protein, minerals, sugar, antioxidants, and phytosterols. Nutritional and medicinal activities of date pits are related to their chemical composition. Many studies indicate that date pits have antioxidant, anti‐inflammatory, gastroprotective, antiviral, hepatoprotective, nephroprotective, and gonadotropic activities. Date pits have shown a potential application in the food, fermentation, chemical, and feed industries. In this paper, we review chemical composition, nutritional and medicinal value, and the utilization of date pits.

“…The proximate analysis on DM basis showed that ground DP applied in this study contained: 6.3% moisture, 9.4% EE, 45.5% ADF, 71.23% NDF, 5.7% CP, 3.25% ash, 0.33% calcium, 0.12% phosphorus, 0.05% sodium and 0.6% potassium. Results fall within the range of DP values previously reported by many researchers (Al‐Farsi et al., ; Dayani et al., ; Hussein et al., ; Najib & Al‐Yousif, ). Recently, Habib and Ibrahim () have studied the nutritional quality (dietary fibre, proximate analysis and micronutrients) of 18 leading varieties of DP cultivated in the United Arab Emirates.…”

This experiment was carried out to study the feeding value of ground date pits (DP) (Phoenix dactylifera L.) with and without enzyme supplementation on laying hens' performance. Apparent metabolizable energy value of DP was determined by the total collection method using 10 adult Leghorn cockerels. After that, a total number of 144 Lohmann 50-week-old LSL-Lite hens were randomly allocated into six groups consisting of four replicates of six birds, based on a 3 × 2 factorial arrangement of the treatments. Six iso-caloric and iso-nitrogenous experimental diets including I-corn-soya bean meal-based control, II-corn-soya bean meal oil-based control and III- corn-soya bean meal-based diet (180 g/kg DP) were formulated. Each of the diets was supplemented with two levels of an enzyme (0.0 and 0.07 g/kg Natozim Plus). The experiment lasted 10 weeks after 7 days of adaptation. The results revealed that there was no significant difference in feed intake, feed conversion ratio, egg production, egg mass, eggshell weight, eggshell thickness and Haugh unit among the treatments. Dietary inclusion of DP significantly decreased body weight gain (BWG), egg weight and yolk colour score. On the other hand, corn-soya bean meal-based control diet with vegetable oil significantly increased egg weight and BWG of birds in comparison with other treatments. The serum biochemical metabolites were not affected by DP and enzyme supplementation. Thus, DP can be used as alternative feedstuff in laying hen diets, up to 18% of the diet with little effect on the performance of hens, including egg weight, and also, it had an adverse effect on yolk colour. Eventually, in terms of performance, the results failed to demonstrate any positive effect of Natozim Plus on either the controls or 18% DP diets.
