Abstract

This study was designed to evaluate the efficacy of organic acid salt Zn from complete feed silage based on corn by product as an alternative to subtitute antibiotic function as a growth promotor for broiler. Ninety day old commercial Cobb broiler chickens were randomly distributed into six groups having three replicates of five birds in each group. Negative control (R0) birds were offered standard basal diet and no challenged, positive control (R1) birds were offered standard basal diet and challenged with 107 Salmonella typhimurium. Treatment R2, R3, R4 and R5 were challenged by 107 CFU of Salmonella typhimurium which added in feed with 0.1% flouroquinolone, 0.1%, 0.2%, and 0.3% of organic acid salts. The result showed that dietary of organic acid salts affect consumption, weight gain, and final body weight (P<0.05). Meanwhile, feed conversion (FCR) was not affected by antibiotics nor  organic acids. Our conclusion, Dietary organic acid salt from complete feed silage corn based by product until dose 0.2% can improve the performance of broiler chickens infected Salmonella typhimurium.

Abstract

The study was conducted to evaluate fermentation quality of complete feed silage based on corn, palm and cassava by products. Each complete feed was ensiled separately in 50 litres silo and were opened 6 weeks after ensiling. The silage products were evaluated in terms of physical (colour, smell, and presence of moulds), chemical (pH, N-amonia content, WSC loss and dry matter loss) and microbial properties (number of lactic acid bacteria). The data was analyzed by using Completely Randomized Design with three treatments and six replications, followed by LSD test. The result showed that all complete feed silage treatments were having good quality. Fermentation quality of silage was affected with  kind of complete feed silage (P<0.05). In general, all of treatments had good fermentation quality of silage, because it have lower pH, ammonia content, WSC loss and dry matter also. It is concluded that quality fermentation of complete feed silage based on corn, palm and cassava by products had good quality and can be recomended as ruminant feeding.

Abstract

Tannin is one of plant secondary metabolites that could protect proteins from various microbes, both in feed material and in rumen. Tannin can be used as an additive in the silage production process, especially high-protein feed material. The study aimed to evaluate the physical quality of soy sauce by-product silage treated with Acacia mangium Wild. tannin (AT; condensed tannin). This study used the fresh soy sauce by-product, tannin of acacia and chestnut (CT; hydrolysable tannin), BAL and propionate acid (PA). Soy sauce by-product was fermented in silo with a capacity of 1.3 Kg. This experiment was arranged in a complete randomized design with 6 treatments and 3 replications. The treatments were (R1) fermented soy sauce by-product, (R2) R1 + BAL, (R3) R1 + 2% AT, (R4) R1 + 2% CT, (R5) R1 + 0.5% PA and (R6) R1 + combination of 1% AT, 1% CT and 0.5% PA. The observed variables were the loss of dry matter (%), temperature (⁰C), smell, color and emerged fungus on silage. Analysis of variance was performed by SPSS version 23. For any significant difference between treatments was evaluated by DMRT at level of confident 5%. The result showed that AT suppressed the loss of dry matter up to 0.91%, and produced no smell with black color such as soybean color. The silage temperature was relatively similar for about 28.9-29.4 ⁰C, no emerged fungus, and did not able to maintain the normal silage temperature. Nevertheless, the use of acacia tannin could produce a good quality soy sauce by-product silage.
