Improving the nutritive value of cassava bioethanol waste using fermented yeast as a partial replacement of protein source in dairy calf ration

Three experiments were conducted with broiler chickens to study the effects of replacing commercial Herring fishmeal with fishmeals prepared form crayfish, sardine, mudskeeper and mullet. In the first experiment, there were no significant differences in the performance, carcass dressing percentages and the composition of the hearts and livers when any of the locally prepared fishmeals replaced the commercial fishmeal in rations. Rations without fish meal depressed performance and carcass/neck dressing percentages significantly but did not affect the composition of the hearts and livers. In experiment 2, the fishmeals were fed at a supplementary level of 7.5% and at a level (20%) in which they constituted the only source of supplementary protein. In this experiment, performance of birds fed 7.5% of the different fishmeals were similar to those observed in the first experiment. When the fishmeals constituted the sole source of supplementary protein, performances of the birds were similar for all fishmeals and were better than when 7.5% fishmeals was fed in the ration in addition to groundnut meal. The ration containing groundnut meal as the sole supplementary protein source depressed performance of birds. In Experiment 3 the total protein efficiency ration (TPE) of the different fishmeal rations were assessed. The TPE for all the fishmeal ration were not significantly different and were significantly better than that of rations without fishmeal

Sorghum grain (SG) contained more crude protein (103.5 g/kg) and ash (17.0 g/kg) but less crude fiber (17.7 g/kg) and total lipid (22.6 g/kg) than corn. The SG contained 0.37% ± 0.02 tannin, had a higher apparent metabolizable energy value than corn or wheat and contained all of the amino acids considered essential for chickens at levels in general between those of corn and wheat. Two experiments were carried out to ascertain the nutritive value of SG as a partial replacement for corn and wheat in practical poultry diets using 320 male and 320 female Cobb chicks in each. Starter (finisher) diets fed from 0–21 days (22–42 days) contained the following levels of SG: 15 (19); 30 (39); 45 (58)%. The diets were isoenergic and isonitrogenous. The inclusion of up to 45% SG in the starter diet and up to 58% in the finisher diet had no significant effect on mortality, live body weight, feed conversion or percentage of grade A carcasses.

Alfalfa Meal

<p>The purpose of the present study was to evaluate the effects of including white lupin bran (WLB) in a fattening rabbit diet on growth, carcass traits and nutrient digestibility. The C diet (control) based on alfalfa meal, whereas the WLB 5 and WLB 15 diets were based on white lupin bran (crude protein 152 g/kg, neutral detergent fibre 524 g/kg as-fed basis). The WLB 5 diet contained 50 g of white lupin bran/kg instead of 50 g of alfalfa meal/kg, whereas the WLB 15 diet contained 150 g of white lupin bran/kg, 5 g of soybean meal/kg and 10 g of sugar beet pulp/kg instead of 165 g of alfalfa meal/kg. The diets had similar digestible protein/digestible energy ratios. A total of 150 Hyplus rabbits between the ages of 30 to 73 d were randomly allocated into one of 3 groups and fed one of the 3 experimental diets. Additionally, another 30 Hyplus rabbits (10 per dietary treatment) at the age of 30 d were selected to determine coefficients of total tract apparent digestibility (CTTAD) of diets between 63 and 67 d of age. The dietary treatments did not affect the final live weight of rabbits (mean=2969 g). There was a higher feed intake (+30 g/d; P<0.001) in both groups of rabbits fed the WLB 5 and WLB 15 diets compared to rabbits fed the C diet, which led to impaired feed conversion ratios (P<0.001). Sanitary risk index was not affected by dietary treatment. The rabbits fed the WLB 15 diet exhibited a higher drip loss percentage (+0.65%; P<0.001) than the rabbits fed the other diets, as well as a lower dressing-out percentage (by 1.6%; P=0.024). The CTTAD of the lignocellulose fraction (acid detergent fibre) was significantly higher in rabbits fed the WLB 5 and WLB 15 diets than in those fed the C diet. White lupin bran may be used as a dietary fibrous by-product without significant impairment of the nutritive value of the diet. This lupin by-product can be included in diets for fattening rabbits up to 15% as a partial replacement of alfalfa meal.</p>

And Control

The demand for aquafeed is expected to increase in the coming years and new ingredients will be needed to compensate for the low fish meal and oil availability. Microalgae represent a promising matrix for the future aquafeed formulation, however, the high production cost hinders its application. The use of microalgae from biorefinery would reduce the disposal costs for microalgae production. The present study aimed to (i) verify the growth of microalgae on digestate coming from pig farming and (ii) evaluate their potential valorization as dietary ingredient in aquafeed according to a Circular Bioeconomy approach. For these purposes, a microalgae biomass was produced on an outdoor raceway reactor supplied with digestate and used for partial replacement (10% of the diet) in aquafeed for Siberian sturgeon fingerlings (Acipenser baerii). The results obtained confirm the feasibility for growing microalgae on digestate with satisfactory productivity (6.2 gDM m−2 d−1), nutrient removal efficiency and Chemical Oxygen Demand reduction; moreover, the feeding trial carried out showed similar results between experimental and control groups (p > 0.05), in term of growth performance, somatic indices, fillet nutritional composition and intestinal functionality, to indicate that microalgae from biorefinery could be used as protein source in Siberian sturgeon aquafeed.

Four experiments were carried out to ascertain the nutritive value and quality of oat groats (OG) as a partial replacement for corn and total replacement for wheat in practical diets for broiler chicken using one commercial broiler genotype, Cobb. In each of experiments 1 and 2, 360 day-old chicks of each sex were housed in Petersime batteries and fed starter (1–21 days) and finisher (23–42 days) diets containing 0, 200 and 400 g of Eastern (E) OG or Western (W) OG/kg. In each of experiments 3 and 4, 320 day-old chicks of each sex were housed in eight floor pens and fed starter diets containing 0, 400 and 600 g EOG/kg and finisher diets containing 0, 400, 600 and 800 g EOG/kg. Feeding up to 600 g/kg OG in starter diets and 800 g/kg in finisher diets had no significant adverse effect on biological performance or monetary returns.
