“…Although positive effects have been reported on poultry consuming chitosan or buckwheat alone (Hirano et al, 1990;Razdan & Pettersson, 1994;Kondo & Osad 1996;Tanaka et al, 1997;Mei 2011), this is the first report on positive lipid profile-changing effects of buckwheat with trace amounts of chitosan. Several animal studies have confirmed that supplementing chitosan at up to 50 g/kg in feed has no negative effects on the growth and feed intake of the treated animals (Kobayashi et al, 2002;2006;Han et al, 2007;Hossain & Blair, 2007;Khambualai et al, 2009;Yan & Kim, 2011). Results in the present study agree with those findings as no detrimental effects of chitosan at up to 500 mg/kg were recorded.…”

This study was conducted to evaluate the effects of different levels of buckwheat (Fagopyrum esculentum) alone or in combination with chitosan, in broiler diets, on the growth, feed intake and serum lipid profile of broilers. Starting as 10-day olds, 144 Cobb 500 broiler chicks were fed six manually prepared diets containing 0%, 10%, 20% or 30% buckwheat, or 10% buckwheat supplemented with 250 mg chitosan or 500 mg chitosan/kg. The trial lasted 32 days. Buckwheat alone or in combination with chitosan had no effects on the growth and feed intake of the broilers. Until 15 days lipid profiles in blood sera did not change in birds fed buckwheat alone or buckwheat in combination with chitosan. However, at day 30 the inclusion of 10% -30% buckwheat alone and 10% buckwheat with 250 mg chitosan/kg or with 500 mg chitosan/kg showed a significant increase in serum HDL-cholesterol concentration and a decrease in total cholesterol, triglycerides and LDL-cholesterol concentrations in the serum compared with the control. This demonstrates for the first time that the feeding of higher levels of buckwheat (20% or more) alone or lower levels of buckwheat (10%) with trace amounts of chitosan influenced the lipid profiles of broilers positively. Because hazardous antibiotics are banned in poultry feed, including of buckwheat with trace amounts of chitosan in broiler diets might be a useful alternative to antibiotics in the poultry industry.

“…Broiler chickens supplemented with either 0.5 or 1.0 g/kg chitosan in diet tended to have better growth and feed conversion efficiency since chitosan probably played a vital role in regulating intestinal microflora including enhancing digestion and absorption of protein (Shi et al 2005). However, male Marshall Chunky broilers fed with 0.6 g/kg chitosan for 7 weeks of age could improve BWG and feed intake but had no difference in feed efficiency (Khambualai et al 2009). It should be noted that the results of growth performance in broiler chickens from several studies were different, possibly owing to a variety of chitosan characteristics such as concentration, degree of acetylation and molecular weight (Goy et al 2009;Khambualai et al 2009).…”

The highest mortality rate of chicks in group 3 during finisher period may be due to high temperature (30 C) and relative humidity (80%) chito-oligosaccharide (COS) at 0.4% level had higher WBC number than other groups at 42 d of age.…”

Percentages of antimicrobial resistance to Salmonella and Escherichia coli in poultry products were high in Thailand, thus, alternative to antibiotic growth promoter is required. The objective of this experiment aimed to examine the effect of dietary chitosan in broilers on blood and intestinal changes. Total of 392, day-old male Ross 308 broilers were allotted into four groups. Broilers in the control group (group 1) received commercial corn-soybean meal-based basal diet. Chicks in group 2 received basal diet supplemented with 200 ppm amoxicillin. Chitosan was added into the basal diet at 1 and 2 g/kg in groups 3 and 4, respectively. Data on growth performance as well as blood and digesta samples were collected on d 21 and 39. The results showed that 2 g/kg dietary chitosan significantly improved feed conversion ratio (FCR) during d 22-39 and 1-39 (p < .05). This level of chitosan also increased the ratio of villus height (VH) and crypt depth (CD) (p < .05) while decreased the CD (p < .05). The supplementation of 1 and 2 g/kg chitosan in diet tended to reduce the ammonia-nitrogen in colonic digesta. Furthermore, both levels of chitosan enhanced number of Bacillus spp. while decreased number of E. coli (p < .001) leading to increased ratio of Lactobacillus and E. coli (p < .001). There were no significant effects on the heterophil (H): lymphocyte (L) ratio and coefficient of apparent ileal digestibility. In conclusion, the supplementation of 2 g/kg chitosan in broiler diets could be used as an alternative additive to antibiotic with its improvement on gut function. ARTICLE HISTORY

“…Some studies in broilers indicated that dietary chitosan treatment groups could gain superior performance and feed conversion ratio than the control group (Suk, 2004;Khambualai et al, 2008Khambualai et al, , 2009). Tang et al (2005) also reported that chitosan could improve the growth performance and feed efficiency of piglets.…”

ABSTRACT:The present experiments were conducted to investigate the effects of dietary chitosan on growth performance, nutrient digestibility, and digestive enzyme activities in weaned pigs. A total of 180 weaned pigs (35 days of age, 11.56 ± 1.61 kg of body weight (BW)) were selected and assigned randomly to 5 treatments containing 0, 100, 500, 1000, and 2000 mg chitosan per kg feed, respectively. Each treatment involved six replicate pens and six pigs per pen. On days 14 and 28, all pigs were weighed and six from each treatment (one from each replicate pen) were killed, and the contents of the stomach, jejunum, and rectum were collected and used for determining nutrient digestibility and digestive enzyme activity. The results showed that supplementation of chitosan improved quadratically average daily gain (ADG) (P < 0.05). Moreover, dietary chitosan quadratically (P < 0.05) increased apparent digestibility of crude protein (CP) on days 14 and 28, and quadratically increased apparent digestibility of dry matter (DM) on day 14 and of Ca and P on day 28, whereas decreased (P < 0.05) apparent digestibility of ether extract in comparison with the control diet. In addition, dietary chitosan quadratically increased (P = 0.062) amylase activity of proximal jejunum and decreased (P < 0.05) lipase activity of distal jejunum compared with the control. These data indicated that diets supplemented with increasing levels of chitosan (0, 100, 500, 1000, and 2000 mg chitosan per kg) quadratically improved ADG of weaned pigs. The growth-promoting action was achieved probably by improved digestibility of major nutrients (DM, CP, Ca, and P) and increased amylase activity of jejunum.
