CASSAVA AS NEW ANIMAL FEED IN EGYPT 3 - PELLETED COMPLETE CASSAVA FEED FOR GROWING RABBITS

[EN] Forty New Zealand White rabbits (20 males and 20 females) aged 5 weeks, of 735g in average weight, were divided into two groups on basis of weight and sex. A pelleted complete rabbit feed containing 45 % cassava products (CCF diet) as 30 % root meal + 15 % leaf meal, was formulated to be fed in comparison with a commercial feed (AF diet ; Atmida Cº) during the 15 weeks of experiment, divided in 3 stages of 5 weeks. 1 % urea was added to the CCF diet in arder to increase the N-content. The results indicated that CP digestibility and N-balance of CCF were significantly (P<0.05) lower than that in AF diet in the first 5 weeks after weaning (1st stage). But the CP digestibility and N-balance were not significantly different between two Qroups fed CCF and AF diets at 15 weeks after weaning (3rá stage). The CF digestibility was not significantly affected by type of feed and it was improved by advance in age of rabbits fed CCF or AF diets. In contrast N-balance was decreased with advancing of age of two groups of growing rabbits. No significant effect of sex was observed on digestibility or N-balance. The feed intake was significantly (P<0.01) lower with CCF diet than that with AF diet in 1 st and 2nd stages. Daily body gain was significantly (P<0.01) lower with rabbits fed CCF than those fed AF diets in 1 st stage but it was nearly similar between two groups at 2nd and 3rd stages. Feed conversion (feed/gain) was more efficient with rabbits fed AF than those fed CCF diets at 1 st stage but opposite trend was observed in 2nd and 3rd stages of growth. Slaughter and carcass traits showed no significant differences between the two groups fed CCF and AF diets. There were no significant differences in feed intake, feed conversion and daily body gain between male and female rabbits. Conclusively, it could be appear that cassava products (roots and leaves) can be used satisfactorily as the partial substitute for traditional energy and protein supplements to formulating pelleted diet for growing rabbits.[FR] Quarante lapins Néo-zélandais Blancs (20 males et 20 feme/les) agés de 5 semaines, pesant en moyenne 735g ont été divisés en deux groupes compte tenu de leur sexe et de leur poids. lis ont rer;u au cours des 15 semaines d'expérience, soit un aliment granulé complet (CCF) contenant 45 % de manioc (30 % de farine de racines et 15 % de farine de feuilles) soit un aliment complet (Atmida CJe) du commerce (AF). 1 % d'urée a été ajouté au régime CCF afin d'augmenter la teneur en azote. Les résultats indiquent que la digestibilité des PB et le bilan azoté du régime CCF etaient significativement plus bas que ceux du régime AF dans les 5 premiares semaines apres le sevrage (1 ere période). Mais la digestibilité des PB et le bilan azoté n'étaient pas significativement différents entre les deux groupes (CCF et AF) 15 semaines apres le sevrage (3eme période). La digestibilité de la cellulose brute n'était pas affectée par le régime, par contre, elle s'est améliorée avec l'age. A l'inverse, le bilan azoté s'est dégradé avec l'age, au sein des deux lots. Aucun effet de sexe n'a été observé pour la digestibilité ou le bilan azoté. La consommation était significativement plus basse (P<0.01) avec le régime CCF qu'avec le régime AF au cours des 1 ere et 2eme périodes. Le gain de poids journalier était significativement plus bas avec l'aliment CCF qu'avec l'aliment AF au cours de la premiare période mais il était presque identique dans les deux groupes au cours des 2eme et 3eme périodes. L'efficacité alimentaire était supérieure avec l'aliment AF comparé a l'aliment CCF pendant la premiare période, mais une tendance contraire a été observée durant la 2eme et 3eme périodes de croissance. Les caractéristiques d'abattage et de carcasse ne présentaient pas de différences significatives entre les deux groupes. 11 n'y avait pas de différences significatives entre males et feme/les concernant la consommation, /'indice de consommation et le gain de poids journalier. En conclusion il apparait que le manioc (feuilles et racines) peut etre utilisé de maniere satisfaisante comme substitut partiel des composants traditionnels énergétiques et azotés dans des formules d'aliments granulés pour lapins en croissance.Abd El-Baki, S.; Nowar, M.; Bassuny, S.; Hassona, E.; Soliman, E.

Study on ontogenetic changes in the content of macro components (Proteins, oil and sugar) of vegetable soybean (glycine max L. merr.) seeds

Based on this, a three-year study was conducted from 2016 to 2018 at Federal State Budgetary Scientific Institution “Federal Scientific Vegetable Center”, Moscow, Russia to evaluate the total accumulation of protein, oil and monosaccharides as the main macro components in the stage of technical (R6) and biological (R8) ripeness of vegetable soybean seeds which are directly used for food. The content of protein, fats and monosaccharides in the R6-stage of vegetable forms of soybeans were 29.4%, 10.5% and 15.6%, respectively, while their protein content and oil content were 9.5% and 51.4% in grain varieties, as well as the content of monosaccharides in vegetable forms exceeded the same indicator in grain varieties by 29.1% (in relative values). During the transition of plants from the R6 to R8-stage, an increase in the accumulation of all macro components were observed, however, it was not the same in breeding varieties. In the R8-stage, the accumulation of protein, fat and sugars in vegetable soybeans were 45.9%, 15.6%, 18.6%, respectively; at the same time, the content of protein and monosaccharides in the grain varieties exceeded by 15.7% and 20.4% (in relative values), respectively, and the oil content of seeds was less by 22.0% (in relative values). It could be concluded that vegetable-type of soybean has other patterns of accumulation of the macro components in the seeds, different from the grain-type varieties of soybean in the Central region of the Non-chernozem zone of Russia. © 2020, Gaurav Society of Agricultural Research Information Centre.
