Abstract
Sixteen crossbred growing pigs Duroc x Landrace, (10 weeks of age; initial body weight 27 ± 3.92 kg) were allotted into four treatments in a randomized block design to evaluate the effects of inclusion of fermented kepok banana corm (FKBC) in the diet on the nutrient digestibility and mineral Ca and P retention of growing pigs. There were four treatments diets offered: basal diets without FKBC (R0); basal diets + 7% FKBC (R1); basal diets + 14% FKBC (R2); basal diets + 21% FKBC (R3). Results of the study showed that inclusion of 21% FKBC in the diet of pigs significantly reduced (P <0.01) dry matter intake compared to the control diet. There were no significant difference between 14% and 21% FKBC on the intake and digestibility of dry matter of the pigs. However, inclusion of FKBC at the level of 7% showed the optimum digestibility of dry matter, crude protein, and energy with the average value of 66.57%, 83.43% and 70.76%, respectively. In addition, mineral consumption and retention of Ca and P were 14.30 and 9.10 g/day, respectively with the value of mineral retention both Ca and P were 11.90 and 7.50 g/day, respectively. It can be concluded that inclusion of FKBC at the level of 7% increased dry matter digestibility and energy.
Highlights
Pig production in East Nusa Tenggara (ENT) Province, Indonesia is to fulfil meat demands, it uses as savings, as social status and for religious ceremonies, respectively [1]
The measurement of feed consumption included intake of dry matter (DM), Crude protein (CP) and energy were calculated by substracting the daily refusal weight from the weight of the feed offered in the previous day
The kepok banana corm was chosen in the present study as an alternative feed supplementation to pigs due to its potential production during harvesting seasons but low utilisation in ENT Province, Indonesia where the quantity and quality of feed is mainly constrained on pig production
Summary
Pig production in East Nusa Tenggara (ENT) Province, Indonesia is to fulfil meat demands, it uses as savings, as social status and for religious ceremonies, respectively [1]. The utilization of local feed from agricultural by products, on the other hand, are less desirable due to its low nutrients quality. Processing such products that locally available through fermentation by utilizing yeast (Saccharomyces cerevisiae) and fungus (Aspergillus niger) prior to offered to animal as source of feed is necessarily important. Digestibility and Mineral Ca and P Retention of Growing Pigs fermentation since yeast (Saccharomyces cerevisiae) and fungus (Aspergillus niger) contained some enzymes that can broke down the hard part of starch. The present study aimed to evaluate the kepok banana corm fermented with yeast and fungus on growing pig nutrient digestibility and mineral Ca and P retention. The hypothesis was that the FKBC fed to growing pig will increase both the nutrient digestibility and mineral Ca and P retention
