Abstract

The study was aimed to evaluate the effect of Spirulina platensis and Saccharomyces cerevisiae or its combination on egg quality, physiological condition and ammonia excretion of hens at the late lay-ing period. At 81 weeks old, 144 Lohmann Brown layer chickens were divided into four treatment groups included CON (hens fed basal feed), SP (basal feed + 0.3% S. platensis), SC (basal feed + 0.2% S. cerevisiae), and SPSC (basal feed + 0.3% S. platensis + 0.2% S. cerevisiae). At the end of the study, eggs, intestinal mucosa, digesta, excreta and blood sample were collected. Results showed that albumin index was higher (P<0.05) in SPSC group than in CON, SP and SC. The yolk index and yolk colour were greater (P<0.05) in SP and SPSC groups than in CON and SC. The erythrocyte values were high-er (P<0.05) in SP group compared to CON, SC and SPSC groups. The ileum pH was higher (P<0.05) in SP than in CON, SC and SPSC. Lactic acid bacteria counts were lower (P<0.05) in the caecum of SC and SPSC than in CON and SP groups. The lower (P<0.05) counts of lactose-negative Enterobacte-riaceae were shown in SC and SPSC than in CON. The excreta pH was lower (P<0.05) in SC group compared to CON, SP and SPSC groups. There were better (P<0.05) protein digestibility coefficient and nitrogen retention in SPSC group than others. Faecal ammonia decreased (P<0.05) in SP, SC and SPSC groups. In conclusion, S. platensis improved egg yolk index and colour, increased erythrocyte counts and played an important role in maintaining the balance of bacteria in the intestine resulting in reduced ammonia excretion. Dietary inclusion of S. cerevisiae reduced ammonia excretion of laying hens during the late laying period.

Abstract

Restriction of synthetic antioxidants and prohibition of antibiotic growth promoters (AGP) have had an impact on impairing the growth rate of broiler chickens, and hence the alternatives for these additives are urgently needed by broiler farmers. The present study aimed to investigate the effect of Moringa oleifera leaves extract (MOLE), whey protein or their combination on the growth, carcass and meat quality of broilers. A total of 336 broiler chicks were arranged into four groups, including T0 (basal diet with no additive), T1 (basal diet with 1% MOLE), T2 (basal diet with 1% whey protein powder) and T3 (basal diet with 0.5% MOLE and 0.5% whey protein powder). Body weight and feed intake were recorded weekly. Internal organs and meats were obtained on day 42. Results showed that MOLE impaired body weight, body weight gain and feed conversion ratio of broilers (p<0.05). MOLE, whey protein and their blend decreased the abdominal fat content of broilers (p<0.05). Whey increased the moisture content of breast meats (p<0.05). Water holding capacity (WHC) was higher in T2 than in the other breast meats (p<0.05). Among the groups, pH value was highest in T2 breast meat (p<0.05). The lightness values of breast meat were lower in T2 than in the other groups (p<0.05), while the lowest yellowness values were found in T2 breast meat (p<0.05). The WHC was higher in T1 thigh meat than in T2 and T3 (p<0.05). The T1 thigh meat showed higher pH than the T2 group (p<0.05). The T1 thigh meat showed higher redness values than the other groups (p<0.05). In conclusion, MOLE reduced broiler growth and abdominal fat deposition. Whey reduced fat deposition and improved the meat quality of broilers.
