Kata Kunci: Ayam Broiler, Hasil Ikutan Minyak Kelapa Murni (Blondo), Villi Usus Halus ABSTRACT An experiment was conducted to evaluate the responce of broiler small intestine villi to feed containing Virgine Coconut Oil (VCO)-by product, that later on would be called blondo. Broiler d.o.c. of strain Cobb as animal material and was arranged in Completely Randomized Design (CRD) with 5 treatments and 4 replications and each experimental unit consisted of 5 chicken, then sum of 100 chicken were required in the experiment. Treatments in the experiment A, B, C, D, and E were respectively utilization of 0, 7.5, 15.0, 22.5 and 30% blondo in the rations. Treatments: A, B, C, D and E respectively resulted in average of villi height at 3 weeks of age: 0.970, 1.100, 1.195, 0.975 and 0.920 mm for duodenum and 0.735, 0.730, 0.775, 0.745 and 0.588 mm for ileum, and at 6 weeks: 1.325, 1.340, 1.443, 1.143 and 1.140 mm for duodenum and 0.968, 0.928, 0.980, 0.853 and 0.708 mm for ileum. Analysis of variance of the small intestine response to treatments: A, B, C, D and E respectively resulted in highly significant difference (P < 0.01) in height of villi in duodenum and ileum at 3 weeks as well as at 6 weeks experimental period. It is concluded that, there was only until level 15% of blondo utilization that resulted in better respond by broiler small intestinal villi. Key Words: Broiler, Coconut Oil-By Product (Blondo), Intestinal Villi INTRODUCTION Cost in poultry production has increased continously due to limited supply of good quality raw material such as soybean, maize and others. An alternative feedstuff that 666 relatively less utilized is by-product in processing of virgin coconut oil (VCO), which is ussually called blondo. Although blondo is rich in omega fatty acid, protein, enzyme and Lactobacillus (BASWARDOJO, 2005 and PURWATI et al., 2006), due to high crude fat Seminar Nasional Teknologi Peternakan dan Veteriner 2011 content, its quantity utilization in chicken ration might become limitation. Linoleat (omega 6) increased saturated fatty acid absorption in the chicken small intestine. Its deficiency caused growth rate to be suboptimal, fatty liver and high sensitivity to breathing infection (ANGGORODI, 1995). According to WAHYU (1997) linoleat was needed in lipid transportation out from the liver, while oleat (omega 9), linolenat (omega 3) and several monogliserides with bile salt formed micells mixture in the intestine immediately, saturated fatty acid thereafter would be dissolved. VCO-making procedure involved fermentation of coconut milk (SIBUEA, 2004). According to WANG and HESSELTINE (1982) the fermented product would have special flavour and texture and contain antioxidant as well as antibiotics peneciline which could inhibit growth of pathogenic microorganism. FOGARTY (1983) reported that fermented feedstuff would be digested and absorbed better by animal. After had been digested by broiler chicken, ration which containing blondo would be mainly absorbed through epithelial cells of small intestinal villi. The shorter villi might happen due to increment of viscousity in the internal lumen through consumption of more fat, what could also happen through high level of NSP (non starch polysacharides) in the ration (STANOGIAS and PEARCE, 1985). The size of villi and microvilli of small intestine are directly related to the absorbtion capacity of the intestine of chicken (MACARI, 1995, cit. FISCHER DA SILVA et al., 2007; YAMAUCHI et al., 2010). According to FERRER et al. (1995) villi height is the best measurements to show the changes on surface area of absorbtive cells. INCHAROEN et al. (2009) and AWAD et al. (2009) observed that chicken growth performance improvement associated with the increment of its intestinal villi height. Induction of intestinal function in the duodenum could improve the growth performance (RUTTANAVUT and YAMAUCHI, 2010). Therefore, an experiment had been conducted with objective to find out the applicable level of blondo in broiler ration through studying its small intestinal villi response. There was hyphothesis in the experiment that broiler small intestinal villi, in term of their height, did not respond differently the ration containing blondo until level 30%. MATERIAL AND METHOD One hundred broiler chickens of Cobb Strain were used in the six weeks experimental period. At the end of the experiment the chicken were slaughtered for their villi observation. Other utilized utensils consisted of writing facilities, knife, tweezers, embedding cassete, bottles 500 ml, incubator, microtome, flow water facilities and object glass with cover. In experimental work were also needed stuffs such as formalin, alcohol, Harris-Hematoxylin dilution, Eosin dilution, aquadest and paraffine. Chicken were kept in 20 unit of cages that each had measurement of 75 × 60 × 70 cm and in the cages were placed feeding as well as drinking water utensils. The cages had also 60 watt lamp for two weeks as a warmer and since then only light resource was available until the end of the six weeks experimental period. As research material, five chickens were maintained in each cage. As shown in Table 1 the rations were formulated according to the requirement of broiler chicken and attempted to be the same in protein percentage and energy quantity. Blondo as an experimental feedstuff was obtained from CV Barokah in a small city Pariaman, West Sumatra. The experiment was constructed in Completely Randomized Design (CRD) with 5 treatments and 4 replications. The treatments: A, B, C, D and E contained blondo level: of 0, 7.5; 15; 22.5 and 30 % respectively. One unit of the treatments consisted of 5 chicken. Observed variables were height of villi in intestinal parts i.e. duodenum and ileum after 3 weeks as well as after 6 weeks experimental period. Data were analysed by anova (STEEL and TORRIE, 1980) and difference between treatments were computed using DMRT (Duncan`s Multiple Range Test). Experimental work The exparimant procedure consisted of drying the blondo, formulating the rations, preparing the stable, arranging the animal (chicken) material based on CRD with 5 treatments and 4 replications, and managing 667 Seminar Nasional Teknologi Peternakan dan Veteriner 2011 Table 1.

The laboratory works consisted of proximate analysis of feedstuffs and making histological small intestinal objects for determining height of villi in duodenum and ileum at three weeks as well as at six weeks experimental period. RESULT AND DISCUSSION Response of villi height Average height of intestine villi of the broiler is in Table 2 displayed that after chicken consumed the rations of treatment: A, B, C, D and E as long as 3 weeks respectively resulted in 0.970, 1.100, 1.195, 0.975 and 0.920 mm for duodenum, 0.735, 0.730, 0.775, 0.745 and 0.588 mm for ileum and after consumed the rations as long as 6 weeks resulted in1.325, 1.340, 1.443, 1.143 and 1.140 mm for duodenum and 0.968, 0.928, 0.980, 0.853 and 0.708 mm for ileum. It could be viewed from 668 1 Figure 1 that independently for broiler aged three or six week, the highest intestinal villi were obtained when the blondo level was 15%. Until level blondo 15 % in the ration at 6 weeks of age, the height of duodenal villi was similar too but the height of ileal ones a rather higher than those reported by AWAD et al. (2008) and RAHIM et al. (2007) for duodenum and ileum 1.405 – 1.647 mm and 0.545 – 0.774 mm respectively. This difference presumably due to different broiler strains was used. Analysis of variance shown that broiler small intestine villi height significantly responded the blondo containing rations (P < 0.05). As shown in Table 1, there were relatively the same nutrient content in all five treatment rations, except fat concentration. Therefore, it was highly probable that the difference in small intestine response was caused by raising of fat content in the ration through increasing of blondo utilization. DMRT (Duncan`s Multiple Range Test) analysis shown that after 3 as well as 6 weeks experimental period, blondo utilization level 15% increased duodenal villi height, while Seminar Nasional Teknologi Peternakan dan Veteriner 2011 Table 2.

Average height of the intestinal villi (mm) ileal villi only trended to increase after 3 and 6 weeks at blondo utilization 22.5 dan 15% respectively. Increment of blondo level above 15 dan 22.5% high significantly decreased villi height at all four mentioned conditions. The increment or the trend of increment of villi height was due to the beneficial effects of blondo superiorities. SIBUEA (2004) declared that VCO (Virgin Coconut Oil) processing involved fermentation of coconut milk. Blondo as fermentation by product contain antioxidant as well as antibiotics peneciline (WANG and HESSELTINE, 1982), is rich in omega fatty acids, Lactobacillus and crude fat (BASWARDOJO, 2005; and PURWATI et al., 2006). SAKATA et al. (1999) obtained in rats that Lactobacillus casei increased the ileal crypt cell production rate by 40%. SANTIN et al. (2001) also found the increment of villus height caused by probiotic Lactobacillus supplementation in ration although GUNAL et al. (2006) in contrary found that there was no effect of antibiotics in villus height and crypt depth at day 21st or 42nd of age. Reports from VLADEMIROVA and SOURDJIYSKA (1996), JIN et al. (1998) and VOGT et al. (1981) indicated that supplementations of probiotics to rations increased the broiler growth performances, could be seen as the fact of optimal nutrient absorption through increment of intestinal villi height. According to DMRT (Duncan`s Multiple Range Test) analysis that increasing of blondo utilization in the ration up to 15% caused high significantly decreasing duodenal and ileal villi after 3 as well as 6 weeks experimental period 669 Seminar Nasional Teknologi Peternakan dan Veteriner 2011 might be due to the viscous increment in internal lumen of intestine through consumption of more fat. It is displayed in Table 1 that fat content are 5.86, 7.00 and 8.17% in the rations C, D and E, respectively. The demaged intestinal mucosa due to highly viscosity in intestine were observed by STANOGIAS and PEARCE (1985) through utilization of high level NSP (non starch poly saccharides) in the ration. YASAR and FORBES (2000) reported that the decreased in digesta viscosity after exogenous enzyme addition is most likely associated with an improvement in small intestine wall morphology. MATHLOUTHI et al. (2002) mentioned that addition of enzyme to rhy based diets increased villus size and villus height to crypt depth ratio. KOLB (1989) declared that cell membrane consisted of a bimolecular layer of fat stuffs, that contained several proteins in it. This fat layer is flexible and always located in liquid media. The fat consisted mostly of phospholipide, spingolipide and cholesterol. The antioxidants (vitamine E), those could come from the fermented product, like blondo, prevented formation of peroxide from unsaturated fatty acid. Peroxide could disturb plasma membrane and defect the cell. DEITCH et al. (1995) confirmed that intestinal epithelial layer constitutes a barrier that protects the host against luminal pathogens. Reduced proliferation rate of intestinal epithelial caused the intestinal villi to be shorter. CONCLUSION AWAD, W.A., K. GHAREEB and J. BÖHM. 2008.
