Title

Effect of adding rumen modifiers (malate and maltodextrin) on performance parameters, fermented products, and blood metabolites on male Sheep fattening

Pages

  55-64

Abstract

 Background and objective: The high levels of concentrate are used to increase gaining in fattening Sheep. This results in Acidosis, Liver abscess, and Bloat which produce some problems. Using Rumen modifiers can help to prevent these disorders. This study aimed to evaluate the effects of dietary supplementation of Malate (Rumalato), Maltodextrin, and mixture Malate-Maltodextrin on Sheep performance parameters, Rumen fermentable products, and blood metabolites of lambs fed high-concentrate growing diets. Materials and Methods: For this purpose, 48 Shall lambs (46. 1± 4. 1 kg body weight) were randomly assigned to four dietary treatments in a completely randomized design with 12 lambs per treatment for 30 days. The treatment groups were as follows: 1) control: basal diet without any additive, 2) basal diet plus 30 gr Maltodextrin, 3) basal diet plus 15 gr Malate (Rumalato), and; 4) basal diet mixture of 15 gr Malate plus 30 gr Maltodextrin. Dry matter intake, Bodyweight gain, and Rumen fluid were collected 3-5 hours after morning feeding. Rumen parameters were measured for pH and volatile fatty acid at the end of the experiment. Blood sampling was carried out before morning feeding. Blood parameters were defined at the end of the experiment for Glucose, Albumin, Cholesterol, and Blood urea nitrogen. Results: Dry matter intake was higher (P<0. 05) in lambs fed Maltodextrin (1. 86 kg/d) and mixture Malate-Maltodextrin (1. 87 kg/d) than in lambs fed control (1. 79 kg/d) or Malate diet (1. 80 kg/d) (P=0. 03). Bodyweight gain and feed conversion ratio showed no significant difference at the end of the experiment (P>0. 05). However, the average body weight gain showed a tendency towards an increase in lambs fed Malate-Maltodextrin. The level of blood glucose was significant between treatments and it was 79 mg/dl in lambs fed Maltodextrin and 78 mg/dl in Malate-Maltodextrin compared to the control (63. 8 mg/dl) and Malate (65 mg/dl) (P=0. 04). Other blood parameters had no significant difference. Among the Rumen parameters, pH level tended to increase in the lambs fed Maltodextrin and Malate-Maltodextrin compared to other treatments, however, with no significant difference (7. 1 and 6. 9 to 6. 8) (P>0. 05). Other parameters of Rumen fluid such as volatile fatty acids had no significant difference between treatments. Conclusion: To conclude, results of this study showed that adding of Maltodextrin and mixture Malate-Maltodextrin can improve dry matter intake in fattening sheep and this is effective for body weight gain and feed conversion ratio. However, Rumen modifiers are effective for Rumen pH and in the prevention of low pH, therefore, result in the balanced production of Rumen fermentable products.
