Single and combined effects of phytase and citric acid on growth performance, nutrient digestibility, bone characteristics, intestinal morphology, and blood components in meat-type quails fed low-phosphorous diets

Aquaculturists have been concentrating their efforts to design aquafeeds using agro by-products to reduce feed costs. However, the presence of a wide variety of antinutritional factors (ANFs) in plant materials is one of the major obstacles. For this purpose, a 2x2 factorial experiment was established to evaluate the suitability of canola meal with citric acid (CA) and phytase (PHY) supplementation for growth performance, nutrient digestibility and body composition of Labeo rohita fingerlings. Five isocaloric and isonitrogenous diets; D1 (control; without CA and PHY), D2 (CA 15 g/kg+PHY 1000 FTU/kg), D3 (CA 30 g/kg+PHY 1000 FTU/kg), D4 (CA 15 g/kg+PHY 2000 FTU/kg) and D5 (CA 30 g/kg+PHY 2000 FTU/kg) were fed to fish (mean initial weight 7.61±0.31 g) in triplicates for 90-days. The growth performance was significantly increased while feed conversion ratio was decreased with D3 compared to control and other CA and PHY supplemented groups (P<0.05). Furthermore, higher digestibility (%) of nutrients (dry matter, crude protein and ash) and improved whole-body composition was also exhibited by fish fed with D3 (P<0.05). Hence, the above results elucidate that supplementation of 30 g/kg CA with 1000 FTU/kg PHY could be a useful approach for improved growth performance, nutrients digestibility and body composition of L. rohita.

Abstract The aim of this trial was to determine the optimal supplementation mealworm on growth performance, apparent total tract retention of nutrients, hematological traits, immune response, and intestinal morphology in weaned pigs. A total of 180 weaned pigs (Landrace×Yorkshire×Duroc; 6.27 ± 0.15 kg) were randomly allotted to 3 treatments and 6 replicates on the basis of initial body weight and sex. The dietary treatments included a corn-based diet supplemented with 0, 2.5, or 5 % mealworm in 2 phases (0–14 and 15–28 d). The gain to feed ratio (G:F) was higher in pigs fed 2.5% mealworm compared with 2.5% during the first phase. Overall ADG was improved in pigs fed 2.5% mealworm compared with pigs fed 5% mealworm. No improvement in overall ADFI and G:F were observed. No digestibility responses were observed by adding mealworm to the diet, but the digestibility of DM and GE were tended to be higher in pigs fed 2.5% mealworm compared with control in phase 1. The number of monocytes tended to be increased in pigs fed 5% mealworm. The concentration of plasma IgG was higher in pigs fed mealworm, however, the plasma IL-6 was tended to be decreased when mealworm was added to the diet (P = 0.052). There was no change in intestinal morphology with increasing dietary levels of mealworm. The results showed that the dietary supplementation of 2.5% mealworm had beneficial effects on growth performance and immune system, however, no effects were detected on growth performance when 5% mealworm was added to the diet.

Intestinal Ecology

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.
