Evaluation of selected minerals in the blood of crossbred pigs fed toasted soybean hull

Abstract

The significance of the mineral elements in animal nutrition cannot be over emphasized. The presence of mineral elements in animal feed is vital for adequate the metabolic processes. Sixteen (16) crossbred weaned pigs aged eight weeks weighing between 6-7 kg were used in experiment to investigate the effect of feeding varying dietary levels of toasted soybean hull on macro and micro minerals in blood of weaned pigs. The pigs were randomly allotted to four treatments T1, T2, T3 and T4 containing 0%, 5%, 10% and 15% of toasted soybean hull respectively. Water was supplied ad libitum. At the end of feeding trial, two pigs per treatment were selected and blood collected for analysis. Results showed that there were significant (p>0.05) differences in macro minerals. Calcium value ranged from 10.40mg/dL in T1 to11.05mg/dL in T4. Phosphorus ranged from 13.20mg/dL to 17.54mg/dL. Potassium value ranged from 4.65mg/dL to 5.65mg/dL. Magnesium ranged from (3.98mg/dL to 4.80mg/dL). Sodium value ranged from (137.50mg/dL to 143.50mg/dL). Iron, copper and manganese values were significantly (p<0.05) influenced by the dietary treatments with the values ranging from 57.50 – 48.00mg/kg, 42.34 – 31.87mg/kg and 10.95 – 8.85mg/kg respectively. For zinc, the value ranged from 1.04mg/kg to 1.30mg/kg. Based on the findings of this study, it can be concluded that toasted soybean hull could be fed to weaned pigs up to 15% inclusion level without any adverse effects on the macro and micro minerals composition of weaned pigs.\n\xa0\n\xa0\nOn ne saurait trop insister sur l importance des elements mineraux dans la nutrition animale. La presence d elements mineraux dans l alimentation animale est essentielle pour un traitement metabolique adequat. Seize (16) porcs sevres croises âges de huit semaines pesant entre 6 et 7 kg ont ete utilises dans l experience pour etudier l effet de l alimentation de differents niveaux alimentaires de coque de soja grille sur les macro et micro mineraux dans le sang des porcs sevres. Les porcs ont ete attribues au hasard a quatre traitements T1, T2, T3 et T4 contenant respectivement 0 %, 5 %, 10 % et 15 % de la coque de soja grillee. L eau a ete fournie ad libitum. A la fin de l essai d alimentation, deux porcs par traitement ont ete selectionnes et le sang preleve pour analyse. Les resultats ont montre qu il y avait des differences significatives (p>0,05) dans les mineraux macro. La valeur de calcium s est etendue de 10.40mg/dL dans T1 a11.05mg/dL dans T4. Le phosphore tegrait de 13,20 mg/dl a 17,54 mg/dl. La valeur de potassium s est etendue de 4.65mg/dL a 5.65mg/dL. Le magnesium tegrait de (3,98 mg/dL a 4,80 mg/dL). La valeur en sodium varierait de (137,50 mg/dL a 143,50 mg/dL). Les valeurs de fer, de cuivre et de manganese ont etesignificativement influencees (p<0,05) par les traitements dietetiques dont les valeurs vont de 57,50 – 48,00 mg/kg, 42,34 – 31,87 mg/kg et 10,95 – 8,85 mg/kg respectivement. Pour le zinc, la valeur varierait de 1,04 mg/kg a 1,30 mg/kg. D apres les resultats de cette etude, on peut conclure que la coque de soja grillee pourrait etre nourrie a des porcs sevres jusqu a un niveau d inclusion de 15 % sans effets negatifs sur la composition macro et micro-minerale des porcs sevres.
