“…These differences would be related not only to the advancement of the dry season but also to the phenological stages of the trees during harvesting. This observation is similar to those reported by Bayer and Waters-Bayer (1999) and Arbouche et al (2012), which showed that variation in DM content, may be influenced by the stage of development of the plant. The ash contents obtained with A. lebbeck and M. lucida were not influenced by the harvesting periods.…”

Objective: This study is conducted, to know the chemical composition at different periods of the dry season, of four major fodder shrubs (Albizia lebbeck, Leucaena leucocephala, Morinda lucida and Senna siamea), used to supplement poor fodders in animal feed, in the conditions of southeast Gabon. Methodology and results:The leaves of each species were harvested at the beginning, at mid-season and at the end of dry season. They were dried and crushed to determine their chemical composition. The results showed that, with A. lebbeck, the levels of DM obtained at mid-season and the end that one, were higher (P<0.05) than at the first harvest. The levels of DM and CP obtained at mid-season and the end of dry season, with L. leucocephala were higher (p<0.05) than those observed at beginning. Variations of DM and CP levels of M. lucida leaves and DM content of S. siamea leaves were not significant (p>0.05). In addition, catechic tannins were not found in the leaves of S. siamea. However, the variations of this tannins type, observed in the leaves of L. leucocephala, M. lucida and A. lebbeck were not significant (p>0.05). On the other hand, the contents of gallic tannins measured in the leaves of S. siamea decreased at the end of the dry season (p<0.05). Conclusion:Finally, it appears that these species showed few variations in protein, cellulose and tannins throughout the dry season. Taking into account the results obtained, the shrub species studied could constitute good forage in supplementation of poor grass in the dry season. However, L. leucocephala and S. siamea should be used with much moderation for the feeding of ruminants, given the presence of gallic tannins in their leaves. Nevertheless, it would be important to study the digestibility of these forages in the dry season.

“…Using apricot kernel meal as a source of protein in the diets of domestic animals has only been studied among broiler chickens [ 15 ], and sheep used for fertilizer [ 16 ] and is thus not a widespread practice. Nevertheless, several studies have examined the hydrocyanic acid content of apricot kernels [ 17 ]. This rate depends on the variety of apricot grown (sweet or bitter kernels) [ 18 ] and the percentage of each variety in the overall quota handled by the agri-food industry.…”

Aim:The aim of this study was to determine the effects of incorporating the by-products complex of date and apricot on the fattening performance of the New Zealand breed of rabbits, to reduce the economic costs of the food formula.Materials and Methods:A total of 288 young New Zealand rabbits aged 35 days were divided into four equal groups each containing 72 animals and into sub-groups of 6 rabbits per cage, depending on the rate of substitution of corn by date rebus and of soybean meal by apricot kernel meal (0%, 10%, 20%, and 30%).Results:The change in weight from day 35 to 77 and the average daily gain are not significantly different, regardless of the diet. The pH and water content are proportional to the substitution rates (6.4-6.6% and 66.5-68.8%). Meat protein levels increased significantly, in particular for the 10% and 30% groups (+8.1% and 6%) while the fat and mineral content levels decreased significantly, in particular for the 30% group displaying −16% and −17%, respectively. Incorporation of dates and apricot kernel meal into the ration of rabbits reduces the cost of the kilogram of food produced of −9%, with an opportunity cost of 165 Algerian dinars (DZD).Conclusion:The date rebus/apricot kernel meal complex can be used as an alternative to the corn/soybean meal complex at substitution rates of up to 30% without adverse effects on growth rates, feed contribution, or slaughter yield. It improves the chemical composition of the meat and reduces the cost price of the quintal of feed produced.

“…In light of the global economic crisis and the fall in oil prices, emerging countries such as Algeria, which imported all the raw materials used for livestock feed formulas, are forced to find solutions capable of reducing imports while maintaining the purchasing power of the poorest sections of the population. The use of non-conventional foods, such as agricultural and agro-industrial by-products, is a possible solution, even if improving their nutritional qualities requires chemical treatment [ 2 , 3 ]. In oasis zones, the volume of products discarded by packing facilities and of cull from the date processing units (date paste) is quite considerable [ 4 ].…”

Aim:The aim of this study was to determine the effects of incorporating three local oasis by-products [cull dates (CDs), date pedicels (DPs) treated with urea, and juice from rumen content] into the food ration of Ouled Djellal lambs on fattening performance and carcass characteristics.Materials and Methods:The experiment was carried out over 105 days, with an adaptation period of 15 days, on four groups each consisting of 10 male Ouled Djellal lambs aged 7-8 months with an average live body weight of 32±1.5 kg, randomly distributed, and raised in tie stalls. The basic rations were formulated at a rate of 0% (control), 50%, 80%, and 100% substitution of barley straw by DPs treated with urea. The additional rations intended for the experimental groups consisted of 100% substitution of corn by CDs. Before distributed, they were sprayed with rumen content extract (RCE) at a rate of 250 ml/kg.Results:The 100% group displayed a highly significant difference compared to the other groups, with a live body weight of 43 kg (p<0.05), an average daily gain of 191 g, and feed efficiency of 5.08. These three parameters developed in proportion to the rates of incorporation of CDs and pedicels treated with urea. The carcass yield of the 100% group (48.7%) is significantly higher than the other groups while the thickness of back fat is significantly lower. Economically speaking, the profit margin of the 100% group is 30.93 Algerian dinars (DZD) per day per animal.Conclusion:The use of by-products of the date palm (CDs and pedicels) combined with RCE in animal feed with a view to fattening sheep, in particular in oasis zones, represents an alternative in enhancing growth performances and carcass characteristics and offers a relatively cheap prospect for the availability of red meat for populations with low purchasing power.
