Study on the proximate a composition of flesh and other body parts of Clarias gariepinus and scomber scombrus was carried out in January, 2020  using standard procedures. For Clarias gariepinus the highest protein (25.69%) was observed in the head, followed by flesh (21.70%) and while the  lowest protein (18.61%) was discovered in the bone. Highest fats (3.61%) was recorded in the flesh, followed by head (2.25) while (0.80%) recorded in the fins as the lowest fats. In fibre the highest (1.87%) was observed in head followed by (1.72) in the bone. The lowest fibre (0.60%) was reported in the flesh. The highest ash (22.03%) was recorded in fins, followed by bone (19.83%) while the lowest (1.30%) was discovered in the flesh. The highest moisture (75.76%) was recorded in the flesh, followed by fins (73.23) while the lowest (56.48%) was observed in the head. For scomber scombrusthe highest protein (29.44%) was observed in the head, followed by bone (28.40%) and while the lowest protein (24.30%) was discovered in the flesh. Highest fats (6.42%) was recorded in the flesh, followed by head (1.48%) while (0.95%) recorded in the bone as the lowest fats. In fibre the highest (1.11%) was observed in fin followed by (0.69%) in the flesh. The lowest fibre (0.59%) was reported in the head. The highest ash (6.37%) was  recorded in  head, followed by bone (5.07%) while the lowest (0.33%) was discovered in the flesh .The highest moisture (68.68%) was recorded in the flesh, followed by head (66.56%) while the lowest (37.20%) was observed in the fin. .The highest carbohydrate (5.58%) was recorded in the bone, followed by fin (5.28%). The study showed that the best body parts in terms protein content of the two fish samples were the head. The Head has the highest crude protein content thus it can be recommended as a possible effective ways to solve protein malnutrition Keywords: proximate, Scomber scombrus, Clarias gariepinus, head, flesh, fins, bones

In the present study effect of processing treatments viz. blanching and germination on the proximate composition of Pennisetum glaucum (pearl millet) was studied. Proximate composition was analysed by the standard methods determined according to Association of Official Analytical Chemists. Results indicated that moisture content increased significantly after processing treatments. Blanching resulted in non significant increase in ash content of pearl millet grains. The crude protein content of unprocessed pearl millet was 11.55%. The crude protein content of blanched pearl millet grains was 11.27%. Crude protein content of germinated grains was found to be 12.38% as in comparison to 11.55% in unprocessed and 11.27 in blanching treatment. Crude fat content of unprocessed (control), blanched and germinated pearl millet grains were 5.36, 5.09 and 4.55%, respectively. Fiber content increased significantly after blanching and germination processing treatments. Processing treatments not only effect the nutritional composition of pearl millet but also contribute towards enhancement of shelf life.

Feed Utilisation

A fifty-six (56) day experiment was conducted to evaluate the growth performance and feed utilization in Clarias gariepinus fingerlings fed with six iso-nitrogenous diets in which oven-dried melon (Citrillus lanatus) seed peel meal (MSPM) was substituted for yellow maize at 0, 20, 40, 60, 80 and 100% inclusion levels. A total of 270 fingerlings of C. gariepinus (mean weight: 7.40 ± 0.02 g) were randomly allocated into eighteen plastic bowls (50-litre capacity) at 15 fish per bowl and fed the control and experimental diets twice daily at 5% of their body weight. Proximate composition of melon seed peel meal-supplemented diets and fish carcass was determined using standard procedures. Results showed that crude protein was highest (60.75%) in fish fed diet 2 (20% MSPMsupplemented diet) and least (58.21%) in fish fed diet 4 (60% MSPM-supplemented diet). Fish fed diet 2 (20%MSPM-supplemented diet) had statistically (p < 0.05) superior values of MWG (48.27 g), SGR (1.56%/day) and FCR (0.48) beyond which growth and feed utilization indices gradually declined with increased level of MSPM inclusion. This study demonstrated that 20% substitution level of oven-dried melon seed peel meal produced the best growth and feed utilization in C. gariepinus.

Mischkolz, J. M., Schellenberg, M. P. and Lamb, E. G. 2013. Early productivity and crude protein content of establishing forage swards composed of combinations of native grass and legume species in mixed-grassland ecoregions. Can. J. Plant Sci. 93: 445–454. We evaluated the early establishment productivity of forage swards of native, perennial, cool and warm season grasses, and legumes as they have the potential to provide non-invasive, productive, and drought resistant rangelands. Seven species with agronomic potential and a broad native geographic distribution were selected for testing including: nodding brome [Bromus anomalus (Coult.)], blue bunch wheatgrass [Pseudoregneria spicata (Pursh)], western wheatgrass [Pascopyrum smithii (Rydb.)], side oats grama [Bouteloua curtipendula (Michx.)], little blue stem [Schizachyrium scoparium (Michx.)], purple prairie clover [Dalea purpurea (Vent.)], and white prairie clover [Dalea candida (Willd.)]. Forage swards, including all seven monocultures, 21 two-species mixtures and a mixture with all species, were planted in two sites, Saskatoon and Swift Current, Saskatchewan. Western wheatgrass (WWG) had the highest overall plant density and the strongest effect on the forage yield of the forage swards; however, productivity and crude protein content were not reduced when other species were also included in the forage sward. Dalea spp. did not establish as well as the other species, but had the highest crude protein concentrations. This work provides insight into forage sward development at the establishment stage; additional work is required to determine long-term species impacts for well established forage swards.

Dietary Crude Protein

AbstractThis study investigated the effects of 100 g/kg increments of crude protein (approx. 250 (P25) to 550 (P55) g/kg of crude protein) in paired iso-energetic diets on the growth performance of the juvenile Australian short-finned eel (1·83 (s.e. 0·01) g average wet weight). The highest growth response was obtained with treatment P45 followed by P35, P55 and P25. It appeared that food efficiency ratio (FER) increased with increasing crude protein content in low energy diets (treatments P25 and P35). However, 100 g/kg increase in dietary crude protein content (from 450 to 550 kg crude protein per kg diet) in high energy diets resulted in lower FER for treatment P55 than for the treatment P45. The protein efficiency ratio (PER, %) was higher in low protein:low energy diets (treatments P25 and P35) than that of high protein:high energy diets (treatments P45 and P55). The protein productive values (PPV, %) for treatments followed a similar trend to PER in this experiment. The lowest PPV was obtained by the treatment P55 and it was significantly different from that of the other three treatments. A proportional increase in dietary crude protein content in paired iso-energetic diets did not significantly change the whole body protein content. However, a small increase in whole body protein content with increasing dietary crude protein in each group was detected. In conclusion, the present study showed protein sparing effects of lipids and carbohydrates in the diets of the short-finned eel. Further studies specifically investigating the effects of dietary carbohydrate to lipid ratios at different protein levels would improve diet formulation and reduce nutrient impact in intensive recirculation systems.
