“…The levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured according to the method described by Reitman and Frankel (1957), whereas serum creatinine was measured with the colorimetric method and enzymatic determination method described by Henary, Cannon, and Winkleman (1974). In addition, serum total protein, albumin and globulin were determined spectrophotometrically using the methods described by Doumas et al (1981).…”

Nile tilapia, Oreochromis niloticus (average initial weight, 5.91 ± 0.04 g), were fed four isonitrogenous and isolipidic diets for 84 days. The diets contained four levels of yeast extract (CW‐I) rich in nucleotides and β‐glucan: 0 (control), 5, 10 and 15 g/kg diet. Weight gain increased linearly, whereas the feed conversion ratio decreased linearly with increasing levels of yeast extract. The diet containing 15 g/kg yeast extract resulted in significantly better (p < 0.05) specific growth rates and protein efficiency ratios. No significant (p > 0.05) differences were found in dry matter, protein, lipid or ash contents or in haematocrit, haemoglobin or total protein contents among the treatment groups. Blood sample profiles showed an increase in white and red blood cells in fish fed 15 g/kg yeast extract in comparison with the other treatment groups. The fish fed the diets with 10 and 15 g/kg yeast extract had significantly higher albumin and globulin levels than the control group, whereas decreased levels of cholesterol and triglycerides, aspartate aminotransferase and alanine aminotransferase were noted in fish fed the diet with 15 g/kg yeast extract. Histological analysis of the liver and intestine in fish fed the control diet showed a slightly abnormal structure in these organs. Only in fish fed diets supplemented with the highest amount of yeast extract was the structure of the hepatocytes and villi almost unchanged, which indicated that the yeast nucleotides could improve hepatic function and promote liver and gut restoration.

“…Serum creatinine and uric acid levels were measured by calorimetric method and enzymatic determination methods as described by Henary et al (1974). Total serum protein and albumin and globulin levels were determined according to the method described by Doumas et al (1981). The activity of the serum alternative complement pathway component C3 was assayed using C3 kit (Zhejiang Elikan Biological Technology Co., Ltd, Wenzhou, Zhejiang, China).…”

Jatropha curcas seed meal was fermented with Bacillus licheniformis (LFJSM) and Bacillus pumilus (PFJSM) separately using the solid-state fermentation. After fermentation, the crude protein and the total hydrolysed amino acid contents were increased in LFJSM and PFJSM, while fibre content, phytic acid, trypsin inhibitor and saponins were decreased. An 84-day feeding experiment was designed for the nutritional evaluation of LFJSM and PFJSM in Nile tilapia. Seven isonitrogenous (305.47 g kg À1 crude protein) and isocaloric (18.21 MJ kg À1 gross energy) diets were formulated by replacing 0% (control diet), 25% (LFJSM-25), 50% (LFJSM-50), 75% (LFJSM-75) and 25% (PFJSM-25), 50% (PFJSM-50) and 75% (PFJSM-75) of protein from fish meal with LFJSM and PFJSM. The higher weight gain and the best feed conversion ratio were found in fish fed control diet, PFJSM-25 and PFJSM-50, which were insignificantly different. Apparent digestibility coefficient values of dry matter, crude protein, lipid and digestible energy reached a plateau in fish fed PFJSM-25 and PFJSM-50. No significant differences were found in haematocrit, haemoglobin, serum alternative complement pathway components, alanine aminotransferase and aspartate aminotransferase and triglycerides between the control diet, LFJSM-25, LFJSM-50, PFJSM-25 and PFJSM-50 treatment groups. Therefore, these findings suggest that up 50% of fish meal can be replaced by PFJSM in Nile tilapia diets.

“…Plasma glucose was measured based on the method of Trinder (1969), while cholesterol was determined based on the enzymatic method of Allain et al (1974). The total protein concentration and albumin in the plasma were determined based on the methods of Doumas et al (1981) and Doumas and Biggs (1972), respectively, while globulin concentration was computed as the difference between the total protein and albumin concentrations (Mapekula et al 2011). Urea determinations were based on the method by Sampson et al (1980), while creatinine determinations were according to the method by Ambrose et al (1983).…”

An experiment was conducted to investigate the effect of plasma concentrations of the metabolic hormones [Growth hormone (GH), insulin and insulin-like growth factor -I (IGF-I)] and nutritional metabolites (Glucose, cholesterol, total protein, albumin, globulin, urea and creatinine) on the resumption of post-partum ovarian activity in sixteen Friesian-Sanga cows grazing extensively on native grassland. Blood samples were taken from cows from week 1 to 16 post-partum. Cows were classified as having resumed ovarian activity when a plasma progesterone concentration of ≥ 1.0 ng/ml was recorded for two consecutive weekly samples. Based on the resumption of ovarian activity, cows were classified as early-cycling, late-cycling or non-cycling. The concentrations of the metabolic hormones were measured from week 1 to 10, while those of the nutritional metabolites were measured during week 1, 3, 5, 7 and 9 during the study period. The concentrations of the metabolic hormones, GH and insulin were similar (p > 0.05) in the three ovarian activity groups, likewise the concentrations of the nutritional metabolites, glucose, total protein, globulin, urea and creatinine. Plasma IGF-I concentration was higher (p < 0.001) in early-cycling (18.7 ± 0.74 ng/ml) than in late-cycling (12.4 ± 0.75 ng/ml) and non-cycling (10.4 ± 0.91 ng/ml) cows. Plasma cholesterol concentrations were significantly lower (p < 0.05) in early-cycling (1.94 ± 0.15 mmol/l) compared with late-cycling (2.48 ± 0.12 mmol/l) and non-cycling (2.61 ± 0.11 mmol/l) cows. For plasma albumin concentrations, the levels recorded for early-cycling cows were higher (40.7 ± 2.85 g/l) than in late-cycling (34.4 ± 1.97 g/l) and non-cycling (33.6 ± 2.66) cows. The results suggest that cows with lower plasma concentrations of IGF-I and albumin, but higher plasma cholesterol concentrations were at risk of delayed resumption of post-partum ovarian activity.
