    Les tourteaux, principales sources de protĂ©ines vĂ©gĂ©tales, sont les sous-produits de l’usinage des graines traitĂ©es pour en extraire l’huile selon les techniques de pressage Ă  chaud et d’extraction par les solvants. L’objectif de ce travail Ă©tait de produire le tourteau de Tetracarpidium conophorum et Ă©valuer son rendement et sa composition chimique par deux techniques de production : la presse mĂ©canique et la mĂ©thode d’hydrodistillation. Le rendement du tourteau Ă  partir du broyat a Ă©tĂ© de : 73,63% et 72,50% respectivement pour la presse mĂ©canique et l’hydrodistillation. (P> 0,05). Quant Ă  la composition physico-chimique du tourteau, les diffĂ©rences significatives ont Ă©tĂ© observĂ©es (p<0,05) en faveur de la mĂ©thode par presse mĂ©canique notamment sur la MS (91,10% contre 97,63%) ; lipides (10,78% contre 14,46%) ; protĂ©ines brutes (24,63% contre 43,75%) ; calcium (1,94% contre 3,17%) ; phosphore (0,46% contre 0,85%). La faible composition chimique du tourteau en protĂ©ines brutes du tourteau produit par hydrodistillation par rapport Ă  celle du tourteau produit par pression mĂ©canique suscite la maitrise de la tempĂ©rature de l’eau.       Oil cakes are by-products of seeds treated to extract oil by using many ways. The objective of the present study was to produce the oil cake of Tetracarpidium conophorum and to evaluate its yield and their chemical composition by two techniques of production mainly the pressure in cold and the hydrodistillation methods. There was no significant difference in yield in both techniques used. (P> 0, 05). Whereas, chemical composition was significantly higher in oil cake produced by using pressure in cold than by hydrodistillation mainly (p<0,05) the DM (91,10% versus 63%); lipids (10,78% vs 14,46%); crude proteins (24,63% vs 43,75%); calcium (1,94% vs 3,17%); phosphorus (0,46% vs 0,85%). The lower chemical composition of the crude protein oil cake produced by hydrodistillation compared to that of the oil cake produced by cold pressures may be due to the uncontrolled temperature of the water during the process of delipidation.   &nbsp

    Le miel est un produit  qui renferme des propriĂ©tĂ©s nutritives susceptibles de stimuler les performances zootechniques des volailles. L’objectif de cette Ă©tude Ă©tait de dĂ©terminer le taux d’incorporation optimal du miel dans les rations des poulets de chair. Un Ă©chantillon de 105 poussins de chair a Ă©tĂ© rĂ©parti en trois lots de 35 sujets  (tĂ©moin, traitĂ© 1 et traitĂ© 2).Chaque lot a Ă©tĂ© ensuite subdivisĂ© en 5 rĂ©pĂ©titions   de 7 sujets  chacun. Les lots traitĂ©s 1 et 2 ont reçu des doses du miel dans la ration alimentaire respectivement au dĂ©marrage 0,5% et 1%, en croissance 1% et 2% et en finition 1% et 4%. Le premier lot a servi de tĂ©moin. Les lots ont Ă©tĂ© comparĂ©s sur les variables de  la croissance pondĂ©rale.   Les rĂ©sultats ont montrĂ© au cours de la phase de dĂ©marrage une amĂ©lioration significative (P < 0,05)  de  la consommation volontaire des aliments (30,5 g contre 34,8 g), du GMQ (22,7 g/jour contre 23,4 g/ jour), l’IC (1,3 contre 1,4) et le poids vif Ă  14 jours (359g contre 377 g). Par contre au cours de la phase de croissance, aucune diffĂ©rence significative n’a Ă©tĂ© notĂ©e dans la ration contenant 1% de miel. En revanche pendant la phase de finition, une amĂ©lioration significative a Ă©tĂ© observĂ©e sur tous les paramètres Ă©tudiĂ©s. Cette Ă©tude suggère l’utilisation du miel Ă  la dose de 0,5% pendant les phases de dĂ©marrage et de croissance et Ă  1% au cours de la phase de finition.   Honey is a natural bee product containing nutritional properties able to stimulate the performance of poultry. The study aimed to determine the optimal rate of honey in the  diets of broiler. A sample of 105 chicks has been randomized and then divided into three groups of 35 chicks each (One control and two treated groups). Then each group was then divided in 5 replicates of 7 chicks. The treated groups received doses of honey at the starting 0.5% and 1%, in growing 1% and 2% finally in finishing stage 1% and 4% respectively. Groups were compared on the growth parameters. The results showed that during the starting stage, a significant improvement (P < 0.05) was observed on feed intake (30.5g vs 34.8g), DWG (22.7g per day vs 23.4g per day), feed efficiency (1.3 vs 1.4) and body live weight (359 vs 377g at 14 days). However, during the growing stage, no significant difference was observed on feed containing 1% of honey. Moreover, during the finishing stage, all the studied parameters were improved by honey at 1%. Therefore, the present study indicated the useful of honey at 0.5% during the starting and growing stages while 1% may be used during the finishing stag

    The indigenous BatĂ©kĂ© hen (Gallus gallus) has low productivity due to various constraints such as feeding sources. The aim of this study was to improve the productivity of the local hen using a new local protein source: Tetracarpidium conophorum meal. Ninety-six chicks 21-day old from the local population were randomized into 3 groups of 32 birds each (TC0, TC4 and TC6), with one replicate. Tetracarpidium conophorum meal was incorporated into groupsTC4 (4% Tcconophorum oil cake and 11% soya oil cake), TC6 (6% T.conophorum oil cake and 9% soya oil cake) whereas TC0   served as a control group (0% T.conophorum meal and 15% soya oilcake). The experiment started at 3 weeks and lasted at 20 weeks of age. Chickens were fed ad libithum and had free access to drinkers. The treatment decreased mortality rate (3.12 % versus 9.3), On the other hand the treatment improves significantly (p Ë‚ 0.05).  feed intake (56.8 vs 60.1g per day), feed conversion (6.5 vs 5.7), and carcass yield (65.8 % vs 71.3 %). The final body weight at 20 weeks of age was low in all groups (1.200g versus 1300g) at 4% of incorporation of T. conophorum meal. Meat yield. This study indicated to incorporate T.conophorum oil cake at 4% and reducing soya oil cake  from 15% to 11%) in  a small scale poultry farming in Congo
