Aim:The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power.Materials and Methods:This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])- Spirulina dose interaction (1 or 2 g/kg diet) on growth performance, gut microbiota, and sensory meat quality of growing Japanese quails (1-5 weeks old).Results:Data revealed improvement (p<0.05) of weight gain, feed conversion ratio and European efficiency index due to 1, 2 g (SP)/kg VPD, and 2 g (SP)/kg FMPD, respectively. There was a significant decrease of ileum mean pH value by 1 g (SP)/kg VPD. Concerning gut microbiota, there was a trend toward an increase in Lactobacilli count in both 1; 2 g (SP)/kg VPD and 2 g (SP)/kg FMPD. It was concluded that 1 or 2 g (SP)/kg vegetarian diet may enhance parameters of performance without obvious effect on both meat quality and gut microbiota. Moreover, 1 and/or 2 g (SP) may not be invited to share fish meal based diet for growing Japanese quails.Conclusion:Using of SP will support the profitable production of Japanese quails fed vegetable protein diet.

The use of bone marrow mesenchymal stem cells (BMSCs) has great potential in cell therapy, particularly in the orthopedic field. BMSCs represent a valuable renewable cell source that have been successfully utilized to treat damaged skeletal tissue and bone defects. BMSCs can be induced to differentiate into osteogenic lineages via the addition of inducers to the growth medium. The present study examined the effects of all-trans retinoic acid (ATRA) and curcumin on the osteogenic differentiation of mouse BMSCs. Morphological changes, the expression levels of the bone-associated gene markers bone morphogenetic protein 2, runt-related transcription factor and osterix during differentiation, an in vitro mineralization assay, and changes in osteocalcin expression revealed that curcumin supplementation promoted the osteogenic differentiation of BMSCs. By contrast, the application of ATRA increased osteogenic differentiation during the early stages, but during the later stages, it decreased the mineralization of differentiated cells. In addition, to the best of our knowledge, the present study is the first to examine the effect of curcumin on the osteogenic potency of mouse embryonic fibroblasts (MEFs) after reprogramming with human lim mineralization protein (hLMP-3), which is a positive osteogenic regulator. The results revealed that curcumin-supplemented culture medium increased hLMP-3 osteogenic potency compared with that of MEFs cultured in the non-supplemented medium. The present results demonstrate that enrichment of the osteogenic culture medium with curcumin, a natural osteogenic inducer, increased the osteogenic differentiation capacity of BMSCs as well as that of MEFs reprogrammed with hLMP-3.

The aim of this study was to determine the physical, chemistry, and microbiological quality of goat's milk collected from morning and afternoon milking. A total of 3 of crossbred goat (PE) milk were used in this study. These samples were analyzed for total plate count (TPC), Staphylococcus sp, Escherichia coli, and Salmonella sp. Test anova shown any significant differences ( p<0.05) in Escherichia coli while another microorganisms not significant. For quality physical and chemical anova results showed no difference between morning and afternoon milking. Based on Indonesian National Standard (SNI) for fresh milk No 3141.1-2011, the level of TPC, and Salmonella sp.were still in standard range, while Staphylococcus sp.and Escherichia coli was exceed the standard value. In conclusion, raw milk of goat collected directly from the udder is safe to consume.

Fishmeal (FM) is the main protein source in fish feed. However, it is quite expensive due to its limited resources. Therefore, finding a dietary alternative to the FM to sustain fish production is crucial, and the current study was performed to assess the impact of poultry offal silage (POS) with or without betaine supplementation; as an effective and cheaper alternative to FM; on feed efficiency, growth performance, spleen morphology and intestinal morphometry of Nile tilapia (Oreochromis niloticus) fingerlings. Four dietary treatments were formulated: (1) FM based diet, (2) FM‐B; FM diet +0.7% betaine, (3) POS diet and (4) POS‐B; POS diet +0.7% betaine. Each dietary treatment consisted of three replicates (n = 10/replicate), and the experiment was continued for 16 weeks. By the end of the experiment, spleen and intestine specimens were collected from 15 fish (n = 5/replicate) for histopathological assessment. The results were statistically analysed using GLM procedures of SAS 9.4. Feed efficiency increased in both POS‐B and FM‐B groups (p = 0.01), while body weight and body weight gain showed only weak tendencies towards an increase (p = 0.10 and 0.12, respectively). The villi length was the highest in POS‐B fed group (p < 0.01). In addition, melanomacrophage centres of the spleen increased in both betaine‐supplemented groups (p < 0.01). From our findings, we conclude that betaine supplementation with poultry offal silage improved production performance and immune status of Nile tilapia fish.

Biochemical studies are much more important from the nutritional point of view. This study was conducted to evaluate the difference in nutritional qualities of the commercial seafood (15.10, 14.50, 26.72 and 14.87%) contents of them on dry basis were observed, respectively. Protein was the major organic component of investigated species, followed by carbohydrate. The results elucidated that V. aurea, C. florida and T. carinifera are good sources of protein and carbohydrate, C. glaucum and T. carinifera of minerals and all of them have low fat content. Carbohydrate, lipid and ash content of C. glaucum was found to be significantly (p<0.05) lower than the other species. The present study provides not only the information about the proximate composition but also recommended the consumption of these 3 shellfishes species (V. aurea, C. florida and T. carinifera) as good quality seafood products and more suitable for marketing and consumption. In addition, the whole mount, when available with low price, may be used to push meat type producing animals especially poultry and fishes.

Egypt’s population is growing with the biggest hurdle facing the Government is to secure animal protein. Broilers provide quality protein of reasonable price. This study was conducted to investigate the outcomes of dietary organic betaine (betafin S4) on productive, epigenetic make up of lipoprotein lipase gene (LPL) promoter, some blood biochemical, and economic parameters in male broilers at finishing period. Eighty one commercial Arbor Acre Plus males, 21 days old, were randomly allocated to three groups, with three replicates each in battery cages under thermo-neutral environment till 42 days. The examined groups received yellow corn-soy basal diet, supplemented with 0 (G1), 1.5 (G2) and 3.0 g (G3) betaine/kg diet, respectively. The mRNA expression levels of LPL gene were analyzed by real-time quantitative PCR. Methylation pattern on LPL gene promoter was determined by bisulfite sequencing. Doses of betaine statistically (P ≤ .05) improved tested performance parameters; while carcass yield % and abdominal fat deposition did not achieve significant changes. The expression of LPL mRNA showed an inverse relationship with betaine dose, which illustrated as a trend toward increase in G2 and decrease in G3. Regarding serum biochemistry, both treated groups when compared to control group revealed a significant improvement (P ≤ .01) in albumin level, simultaneously, a significant increase (P ≤ .05) was recorded in uric acid and triglyceride levels, additionally, strong positive (P ≤ .01) correlation between betaine dose and previously mentioned parameters was reported. Betaine is recommended in finishing male broilers as production costs were reduced by 3.97%–4.37% per kg, respectively. In conclusion, incorporation of 0.15–0.30% organic betaine to male broilers diets during finishing period improves the growth performances.
