“…The expected inhibitory effect of dietary supplementation with acetic or propionic acids on feed intake of broiler chicks [5,6,8,9] was also evident in the current study. The most prominent consequence of anorectant supplementation was its pronounced allevia- 112 Pinchasov/Elmaliah Dietary Anorectants and Blood Metabolites tion of feed intake, resulting in decreased body weight gain and AAT weight ( fig.…”

“…The inhibitory effect of these acids on feed intake is assumed to result from intervention in some metabolic pathways. The idea that metabolic events contribute to the control of feed intake is widely accepted [5][6][7][22][23][24][25][26][27], although the mechanism un derlying such metabolic signals is not clear. Langhans et al [23] concluded, from a se lective hepatic vagotomy study with rats, that the hypophagic effect of pyruvate, lactate, glycerol, and malate is mediated through he patic neural structures.…”

The effects of dietary supplementation with acetic or propionic acid, given at a level of 3% of diets containing 2,500 or 2,750 kcal of metabolizable energy per kg, on levels of blood glucose, and on lipid, protein, and energy metabolisms were studied in female broiler chicks. Voluntary feed and energy intakes, as well as body weight gain, decreased significantly with the inclusion of the acids in either diet, in decreasing order of effect: propionate > acetate > nonsupplemented controls. The relative weight of the abdominal adipose tissue decreased significantly with the inclusion of either acid, but was unaffected by dietary energy level. In contrast, the weight of the liver was higher in birds fed the low-energy diet, but was unaffected by the anorectic agents. Inclusion of the acids increased the concentration of volatile fatty acids in the cecum and blood plasma. The rate of clearance of plasma propionate was greater than that of acetate. Anorectic agents and dietary energy density exhibited a synergistic effect on feed intake. These agents altered blood metabolites involved in lipid and energy metabolisms, but not in that of protein. Plasma metabolites and enzymes, particularly β-hydroxybutyrate and alkaline phosphatase, reflected the degree of feed restriction, supporting the hypothesis that the hypophagic effect of these acids is due to metabolic intervention.

“…The results of this experiment are consistent with the findings of , who indicated that the dietary addition of fumaric acid did not affect WG of broilers, but did improve FCR. On the other hand, Pinchasov & Jensen (1989) reported that butyric acid, unlike other acids such as propionic acid, did not reduce feed intake. In the current study, the addition …”

A 2 × 2 × 2 factorial arrangement was conducted to evaluate the effects of cereal type (corn vs. wheat), enzyme supplementation (0 or 0.4 g/kg diet), and sodium butyrate addition (0 or 2 g/kg diet) on growth performance, carcass traits and intestinal morphology of male broilers from 10 to 42 d. A total of 600 male Arbor Acres chickens were assigned to eight dietary treatments in a completely randomized design, providing five replicate pens per treatment. Diets were formulated to meet or exceed NRC nutrient recommendations. When compared with birds fed corn-based diets, chickens fed wheat-based diets had inferior weight gain (1978 vs. 1807 g, p < 0.01) and feed per gain ratio (1.81 vs. 1.93; p < 0.01). Both weight gain (1870 vs. 1915 g; p < 0.01) and feed intake (3511 vs. 3556 g; p < 0.01) were increased by enzyme addition to experimental diets. Feed intake significantly (p < 0.01) increased by sodium butyrate addition to experimental diets; however, no significant differences were observed in weight gain or feed per gain ratio when sodium butyrate added to experimental diets. The birds fed wheatbased diet had higher relative weights of the proventriculus (p < 0.01), gizzard (p < 0.05), liver (p < 0.05), duodenum (p < 0.05), and ceca (p < 0.01) when compared with those fed corn-based diet. Enzyme and sodium butyrate addition had no significant effects (p > 0.05) on the relative weights of the proventriculus, gizzard, pancreas, liver and heart. Cereal type had a significant (p < 0.05) effect on intestinal morphology, including villus height and crypt depth. Jejunal villus height (p < 0.05) and crypt depth (p < 0.01) were improved by sodium butyrate addition. In conclusion, the results of this experiment showed that enzyme and sodium butyrate addition, especially to the wheat based diet, improve growth performance.

“…The inclusion of 0.2% or 0.3% butyric acid did not influence broiler chickens' BWG, FI, or FCR at the whole period of the experiment (Mahdavi and Torki 2009). It has been suggested that in case of well-nourished healthy chicks housing at a moderate stoking density and hygienic condition, dietary inclusion of MCFAs or SCFAs was ineffective on the birds' performance (Pinchasov and Jensen 1989). Free butyric acid is absorbed very quickly in the upper digestive tract, and will likely be of limited use other than as a feed sanitizer, and, unlike other acids such as propionate, did not depress FI (Pinchasov and Jensen 1989).…”

The objective of this study was to determine the effect of short-chain fatty acids (SCFAs; C4 powder) and medium-chain fatty acids (MCFAs; Bergaprime) on performance, carcass characteristics, and some serum parameters of broiler chickens. A total of 200 one-day-old male broiler chicks (Ross 308) were assigned to five dietary treatments, including control diets (C), C plus Virginiamycin (200 g/ton; ANTI) as positive control, C plus MCFAs supplement (1 kg Bergaprime/ton; M), C plus SCFAs supplement (3 kg C4 powder/ton in starter and 1.5 kg/ton in grower and finisher diets; S), and C plus the combination of SCFAs and MCFAs supplement (SM), as mentioned above according to a completely randomized design. Each treatment consisted of 4 replicates with 10 chicks each. There were no significant differences in body weight, feed intake and feed conversion ratio, and carcass traits among the treatments. SCFAs and MCFAs treatments had higher heterophil and lower lymphocyte percentage compared to the control treatment. Blood glucose and cholesterol concentrations were decreased in MCFAs and SCFAs (p < .05). Lipid percentage of thigh meat of MCFAs and SCFAs was decreased. These results indicated that dietary MCFAs and SCFAs positively decreased broiler chicken meat. ARTICLE HISTORY
