Performances and haematological profile of broilers fed fermented dried cassava (Manihot esculenta Crantz)

Abstract

The effect of feeding fermented dried cassava (gathot) on the performances and haematological profile of broilers was investigated. There were four dietary treatments arranged in a completely randomized design, i.e. control diet and diets containing 25, 50 or 100 g/kg gathot. The birds were provided with the treatment diets ad libitum from 8 to 35 days of age. Body weight, feed intake and feed conversion ratio (FCR) were determined weekly. At day 32, the birds were blood sampled, sacrificed and immediately the internal organs and abdominal fat were removed and weighed. Feeding gathot at various levels did not affect (P > 0.05) the growth and FCR, but tended (P = 0.09) to reduce the feed cost per kilogramme live weight gain of broilers. The dietary treatments did not cause toxicological effect on broilers, indicated by the values of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) that were not different from those in the control diet. Dietary inclusion of gathot lowered heterophils to lymphocytes ratio (H/L ratio) (P < 0.05) and albumin to globulin ratio (A/G ratio) (P = 0.14) of broilers as compared to the control diet. Total triglyceride was lower (P < 0.05) in the serum of broilers fed diets containing 5 and 10 % of gathot, when compared with that in the control diet. The treatments resulted in reduced abdominal fat deposition in broilers. In conclusion, dietary inclusion of gathot at up to 10 % had no negative impact on the growth performance of broilers. Feeding gathot has potential to improve the health and physiological stress responses as well as reduce body fat deposition in broilers.

Effects of feeding cassava pulp fermented with Acremonium charticola on growth performance, nutrient digestibility and meat quality of broiler chicks

“…Taken together, the antioxidant capacity of A. charticola grown in AC-FCP diets (Sugiharto et al, 2015;2016b) was perhaps capable of alleviating oxidative stress in broiler chicks and thus the increased production of antioxidants as a natural protective response to oxidative stress did not appear in AC-FCP birds. This inference was supported by Sugiharto et al (2016c), who reported that feeding gathot (fermented dried cassava from which A. charticola was isolated) reduced the heterophil to lymphocyte (H/L) ratio (indicator of oxidative stress) in broiler chicks compared with the control birds. Owing to the limited number of repetitions, however, the interpretation of the current findings should be taken with caution.…”

Effect of decocted turmeric on performance, hematological parameters and carcass traits of broiler chickens

“…Moreover, the lower A/G ratio in this study may further indicate the improvement of immune competence of decocted turmericdrunk broilers. Sugiharto et al (2016a) suggested that the lower A/G ratio implicates in a better immune competence and disease resistance of broilers. Interesting results was seen in the current study, in which drinking decocted turmeric was associated with the lower H/L ratio of chickens.…”

“…This present finding was in agreement with that of previously reported by Hosseini-Vashan et al (2012) when feeding turmeric rhizome powder to broilers under heat stress conditions. The H/L ratio has commonly been used as an indicator of stress and infections in broilers (Sugiharto et al, 2016a;2016b;2017b). In this basis, decocted turmeric seemed beneficial in alleviating the stress and infections in broiler chickens.…”

Recent advances in fermented feeds towards improved broiler chicken performance, gastrointestinal tract microecology and immune responses: A review

“…Feeding fermented products has been commonly practiced in the pig nutrition arena for many years ( Canibe and Jensen, 2012 ), however there is now increasing interest in incorporating fermented feed into broiler rations to take advantages of its positive influences, particularly on gut health and production parameters ( Alshelmani et al., 2016 , Zhang et al., 2016 ). In terms of cost efficiencies, the replacement of expensive conventional feedstuffs such as yellow corn in broiler diets may further encourage the use of cheaper unconventional fermented feedstuffs in broiler nutrition ( Supriyati et al., 2015 , Sugiharto et al., 2016a , Sugiharto et al., 2016b ). This review gathers the current state of the art in chicken broiler nutrition and describes how the application of fermented feed in chicken broiler diets could influences growth performance, gastrointestinal tract microecology and immune responses.…”
