AbstractA 3 ✕ 2 factorial experiment was conducted to investigate the interaction between lactofeed 70 (LF70) (860 g/kg whey permeate, 140 g/kg soya-bean meal, Volac International, UK) levels and soya-bean meal inclusion (SBM) (90 and 225 g/kg) from day 0 to day 25 after weaning (starter period) on growth performance and diet digestibility. A common diet was offered from day 25 to day 38. Dietary treatments were established by substituting LF70 for extruded wheat and soya-bean meal for potato protein (PP) and soya protein concentrate (SPC). Digestible energy and amino acids were maintained by adjusting soya oil and synthetic amino acids. A total of 252 pigs (7·7 kg and 28 ± 2 days of age) were allotted randomly to six treatments containing (1) 0 LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (2) 0 LF70 with 225 g/kg SBM (3) 175 g/kg LF70 with 40 g/kg PP and 40 g/kg SPC and 90 g/kg SBM (4) 175 g/kg LF70 with 225 g/kg SBM (5) 350 g/kg LF70 with 40 g/kg PP, 40 g/kg SPC and 90 g/kg SBM and (6) 350 g/kg LF70 with 225 g/kg SBM. There was an increase in average daily gain (ADG) (0·182 v. 0·292 v. 0·318 kg, s.e. 0·0089; P < 0·001) and food intake (0·413 v. 0·472 v. 0·489 kg, s.e. 0·0139; P < 0·01) and an improvement in food conversion ratio (FCR) (2·31 v. 1·63 v. 1·55 kg, s.e. 0·037; P < 0·001) as the level of LF70 increased during the starter period. From day 25 to day 38, the pigs given the starter diets containing no LF70 had an improved ADG (P < 0·05) and FCR (P < 0·001) compared with the pigs given 175 and 350 g/kg LF70. The pigs offered diets containing 350 g/kg lactofeed had a significantly higher N digestibility (P < 0·05) than the pigs offered diets containing no lactofeed. There was a significant interaction (P < 0·001) between LF70 and SBM in the apparent digestibility of gross energy (GED). Pigs given higher SBM diets had a higher GED at the 350 g/kg LF70 inclusion than pigs given PP + SPC diets. However, there was no difference in GED at the 0 and 175 g/kg LF70 inclusion. In conclusion, the inclusion of LF70 increased ADG, food intake and apparent N digestibility and improved FCR.

This study analyzed the chemical compositions, growth performance and nutrient efficiency of fish meal supplemented with varying percentage of S. indicum). A total of 150 of C. gariepinus fingerlings were grouped into 6 tanks with 20 C. gariepinus per tank. Each tank of fish was served with prepared fish meals supplemented with various levels of beniseed (S. indicum), namely, DT1 (commercial diet), stand as the control group, DT2 (0% beniseed with 100% soya bean meal, DT3 (25% beniseed with 75% soya bean meal, DT4 (50% beniseed with 50% soya bean, DT5 (75% beniseed with 25% soya bean and DT6 (100% beniseed with 0% soya bean, individually. Chemical compositions of each experimental diet and fish carcass were determined and the feed utilization by fishes was equally monitored and calculated. Higher levels of moisture content (7.42%), crude fiber (4.24%), total ash (3.16%), crude protein and fat (29.21 and 30.01%) and carbohydrate (27.21%) were established for the dietary group (DT6) as compared to other dietary groups. In contrast, the fish carcass moisture, crude fiber, and total ash contents were high in fish fed DT4 and DT2 compared to others. Elevated calcium (760.7 and 763.6 mg/100g), phosphorus (683.4 and 685.1 mg/100g), sodium (302.4 and 303.4 mg/100g), potassium (820.6 and 825 mg/100g) and iron (32.67 and 37.31 mg/100g) contents were noted in DT5 and DT6 than the other diets. The fish carcass fed DT6 were richer in calcium (803 mg/100g), phosphorus (5023 mg/100g), sodium (492 mg/100g), potassium (6313 mg/100g) and iron (5.12 mg/100g) than the others. C. gariepinus fed DT6 recorded high weight gains (45.64 mg) while fish DT4 had a value of length gain (1.80 cm). Higher significant values were observed for SGR (54.33%), PER (2.47%), FI (2.85%) and SR (80.23%) as feed utilization in fish fed DT6. However, experimental diets (DT5 and DT6) with 75 and 100% S. indicum inclusion look promising and would enhance adequate growth performance and nutrient utilization of C. gariepinus, which may be used for the development of the product in various food industries.
