Abstract

The objective of the present study was to evaluate the impact of dietary supplementation of formic acid, butyric acid or their combination on carcass and meat characteristics of broiler chicks. A number of 288 day-old-chicks (Lohmann MB-202 meat broilers) were distributed to four groups, including CONT (basal diet with no additive as a control), FORM (basal diet containing 0.1% formic acid), BUTR (basal diet with 0.03% butyric acid) and FORM+BUTR (basal diet with 0.1% formic and 0.03% butyric acid). At day 35 the birds were slaughtered and eviscerated, and from which the breast meat was obtained. Carcass and cut yields of broilers were not different (P>0.05) among CONT, FORM and BUTR birds. The combination of formic and butyric acids increased (P<0.05) the relative weight of back of broilers. Meat pH value was higher (P<0.05) in organic acids treated than in non-treated birds. Organic acids lowered (P<0.05) drip loss of broiler meat. Butyric acid increased (P<0.05) moisture and decreased (P<0.05) the content of meat protein. Formic acid increased (P<0.05), whereas butyric acid and combination of formic and butyric acids decreased (P<0.05) lightness values of breast meat. Yellowness values of meat increased (P<0.05) with organic acid administration. Intense bands of 25 kDa (phosphoglycerate mutase) was observed in most of meat samples from the treated birds, but not in meat from the control birds. In conclusion, dietary supplementation of organic acids was capable of improving the meat quality of broiler meats. The treatments may prevent the pale, soft and exudative (PSE)-like condition in broiler meats.

Abstract

The purpose of the research was to study the effects of feeding inulin derived from Dahliavariabilis tuber powder and extract on the existence of intestinal microbes in crossbred native chickenstarter. Experimental animals were 280 unsex crossbred native chickens and powder and extract ofdahlia tuber as source of inulin, which were started to be fed on day 22. The present experiment wasassigned in a completely randomized design with 7 treatments and 4 replications (10 birds each). Thetreatments were: T0 (basal diet/BD), T1 (BD+0.4% powder form), T2 (BD+0.8% powder form), T3(BD+1.2% powder form), T4 (BD+0.39% extract form), T5 (BD+0.78% extract form), and T6(BD+1.17% extract form). Parameters measured were the number of Lactic acid bacteria (LAB),Escherichia coli, intestinal potential hydrogen (pH) (duodenal, jejunal and ileal), rate of passage anddaily body weight gain (DBWG). Data were subjected to ANOVA and followed by Duncan andpolynomial orthogonal test. The results indicated that feeding inulin derived from dahlia tuber powderand extract form significantly (P<0.05) increased LAB population and DBWG, but decreasedEscherichia coli number and intestinal pH, and slow the rate of passage. In conclusion, feeding inulin ofdahlia tuber powder was optimum at 0.9% but that of extract is linier until 1.17%.

Abstract

This study was conducted to determine the effect of adding Spirulina platensis to replace zinc bacitracin on performance, egg quality, blood profile, total gut bacteria, and liver histopathology of local indigenous Arab chicken (Gallus turcicus). One hundred and eight 28-week-old laying hens were distributed randomly to three treatments: T0 (control diet), T1 (T0 + 1% S. platensis), and T2 (T0 + 0.04% zinc bacitracin). The treatment was applied for 49 days. S. platensis and zinc bacitracin decreased feed intake (p<0.05), but the egg mass had no significant effect; this provides a good improvement in feed conversion ratio (p<0.05). S. platensis helped maintain persistent egg production (p<0.05). S. platensis and zinc bacitracin provided the best results on haugh unit (p<0.05). S. platensis increased the yolk score (p<0.05). Zinc bacitracin decreased erythrocytes (p<0.05) but was not significantly different from S. platensis. S. platensis and zinc bacitracin increased mean corpuscular volume (MCV) (p<0.05). Blood chemical profile and total gut bacteria were not affected by the treatments. S. platensis was the best at maintaining liver’s health (p<0.05). This research concludes that S. platensis can efficiently optimize feed consumption, enhance performance, maintain egg quality, and protect the liver damage of Arab chicken. Therefore, S. platensis could be considered to replace the use of antibiotics.

Abstract

The study aimed to investigate the effect of supplementing chitosan, Bacillus subtilis or blends of both on broiler growth performance, immune response, biochemical variables, and intestinal ecology of broiler chickens. Two hundred and eighty day-old chicks were distributed into 4 experimental groups, including T0 (control, basal feed), T1 (basal feed + chitosan 0.1% feed), T2 (basal feed + B. subtilis 0.01% feed), and T3 (basal feed + chitosan 0.1% feed + B. subtilis 0.01% feed). Variables measurements and sample collection were conducted on day 35. The T3 did not differ from T0 and T1, but they consumed less (p≤0.05) feed than T2 chickens. Feed conversion ratio (FCR) was lower (p≤0.05) in T1 and T3 compared to T0 and T2 groups. Leukocyte counts in T2 and T3 were higher (p≤0.05) than those in T0. The T1, T2, and T3 had higher (p≤0.05) lymphocyte counts than T0. The T3 had lower (p≤0.05) low-density lipoprotein (LDL) levels than the T0 group. The T2 had higher (p≤0.05) levels of total protein and globulin than T3 and T0. Compared to T0 and T3, serum albumin levels were greater (p≤0.05) in T1 and T2. The T3 had higher (p≤0.05) duodenal villi height than that in the other groups. The T2 and T3 chicks had higher (p≤0.05) Newcastle disease titer than T0 and T1. Compared to T2 and T3, T0 and T1 showed a worse (p≤0.05) microscopic structure of jejunum. The T2 and T3 showed lower (p≤0.05) lesion score in bursa of fabricius than that in the other groups. In conclusion, the blends of chitosan and B. subtilis resulted in improved FCR, higher leukocyte and lymphocyte counts, lower LDL, higher duodenal villi height, higher Newcastle disease titer, better microscopic structure of jejunum, and lower lesion score in bursa of fabricius of broiler chickens.
