Effects of treatment methods on the nutritional value of cotton seed cake for laying hens

The effects of treatment methods on the nutritive value of cotton seed cake (CSC) for laying hens were examined. Olympia laying hens (n = 96) were assigned randomly to a 2 × 3 factorial combination of fermented or unfermented CSC supplemented with enzyme, Vitamin E and ferrous sulphate over a 4-week feeding period. CSC was incorporated at 15% in the diets. Results showed no significant differences (P > 0.05) in feed intake, body weight gain and egg weight due to treatments. However, hen-day egg production was significantly reduced (P 0.05). Serum concentration of total protein among dietary treatments was lower (P 0.05) for all treatments. Generally, activities of alanine and aspartate aminotransferases increased (P < 0.05) among CSC dietary treatments compared with the control diet. The interaction between CSC form and additives had no significant effect on any of the parameters. The results of this study indicate that the treatment methods employed for CSC could not significantly improve its nutritive value for egg production at 15% level in the diet of laying hen.

Characterization of the Crystal Structure of Sesame Seed Cake Burned by Nd: YAG Laser

This paper reports obtaining of useful and high-value materials from sesame seed cake (SSC). For this purpose, SSC sample was burned for 30 s using Nd: YAG laser with output power 60 W.

Valorization of Griffonia simplicifolia Seed Oil for Biodiesel Production: A Sustainable Alternative

Bio-derived oxygenated hydrocarbons, such as mixtures of fatty acid methyl esters (biodiesel), are promising alternatives for alleviating the adverse effects of fossil fuel consumption on climate change and preventing petroleum resource depletion. However, the selection of a viable feedstock for competitive biodiesel production remains challenging. Recent studies focusing on Griffonia simplicifolia seeds, the sole plant industrially exploited for 5-hydroxy- tryptophan (5-HTP) extraction, have shown that G. simplicifolia seed oil (GSO) can be solvent-extracted directly from ground seeds or the remaining seed cakes obtained after 5-HTP extraction with quantitative yields. This work documents the conversion of GSO into biodiesel through homogeneous base-catalyzed transesterification. The refractive index and density of the obtained methyl ester mixtures decreased with increasing oil-to-methanol molar ratio, reaction temperature, and time. Under specific conditions, 1.43 wt% FFA oil, 63.5C, 60 min, and 1:9 oil/MeOH molar ratio with 1.2 wt% NaOH or 1.3 wt% KOH as catalysts, optimal reaction conditions were reached. There were no significant differences in the potential for diminution of the refractive index and density between the NaOH and KOH catalysts. The predicted fuel properties based on the fatty acid composition determined by GC-MS showed that G. simplicifolia biodiesel exhibited a cetane index of 50.29, volumetric energy density of 34.97 MJ/L, cloud point of -1.03°C, kinematic viscosity of 4.07 mm2/s, and oxidative stability of 0.65 h. Apart from its unfavorable oxidative stability and slightly lower energy density compared to petrodiesel, all other calculated parameters met the current standards. The valorization concept proposed in this study should be integrated into the 5-HTP extraction process, preferably using the remaining dry seed cakes as raw materials to maximize revenue in a bioeconomic and sustainable approach.

Nutritional value of detoxified Jatropha curcas seed cake protein isolates using rats as an animal model

A bioassay study was conducted to investigate the effects of substituting casein with graded levels of detoxified Jatropha curcas seed cake protein isolates(JPI) as a protein source on the growth performance,feed efficiency ratio(FER) and its protein values using rats as an animal model. Thirty 21-day-old male Spraguee Dawley weaned rats were randomly divided into 5 groups, each group with 6 replications(n = 1). Each group consumed one of the following diets: protein-free, casein(CAS) and JPI diets(JPI20,JPI40 and JPI60; different levels of JPI to replace the casein at concentrations of 20%, 40% and 60% on crude protein basis). Feed intake and protein intake showed no difference among the rats fed JPI20, JPI40 and CAS diets(P > 0.05). However, these parameters were lower in the rats fed JPI60 than in rats fed CAS(P < 0.05). The rats fed diets containing JPI had lower body weight gain, protein efficiency ratio and net protein retention than those fed CAS diet(P < 0.05). When the level of JPI used to replace the casein was lower than 40%, protein efficiency ratio(PER) was close to or higher than 2.0, which suggests that JPI could be viewed as a high-quality protein. Inclusion of JPI in the diet decreased alkaline phosphatase activity. The values were significantly lower in rats fed JPI20 and JPI40than in rats fed CAS(P < 0.05). No histopathological changes were observed in livers and kidneys in the rats fed JPI diets. The results demonstrate that JPI could be used as an efficient protein source at a level of no more than 40% of dietary protein source.

Microbiological Quality of Surface Water Treated with <i>Moringa oleifera</i>Seeds or Cakes during the Storage: Case Study of Water Reservoirs of Loumbila, Ziga and Ouaga 3 Dams in Burkina Faso

Water purification with Moringa oleifera seeds has received a lot of attention because it reduces water turbidity and pathogenic microorganisms. However, it is important to define the optimum conditions of storage to preserve the treated water quality. The study aims to investigate microbial quality of water treated with Moringa oleifera seeds or cake coagulants in relation to the storage temperature and shelf life in order to define the optimum conditions of storage. A total of 45 water samples from 3 water reservoirs of Loumbila, Ziga and Ouaga 3 dams were collected in sterile glass bottles and treated in triplicate with Moringa oleifera seeds or defatted cakes coagulants. Treated water samples obtained at optimum conditions were stored at room temperature (25°C - 30°C) and at 4°C. Fecal bacteria pollution indicators (Escherichia coli, fecal coliforms and fecal streptococcus) and parasites were monitored every 24 hours during three (3) days based on laboratory standard methods. Data were analyzed using the Student’s t-test and XLSTAT 7.5.2 statistical software. From the results obtained, bacterial indicators increased significantly with storage temperature (p and shelf life (p . However, for all water samples, bacterial growth was more important in samples treated with Moringa oleifera cakes than seeds (p . For water samples treated with Moringa oleifera seeds and stored at room temperature, bacterial increase after 72 hours was 57 - 80, 42 - 50 and 22 - 47 CFU/100 ml for fecal coliforms, E. coli and fecal streptococcus, respectively. With Moringa oleifera cake’s treatment, the increase was 63 - 104, 57 - 82 and 28 - 52 for the same indicators, respectively. Bacterial growth was also more important at room temperature than at 4°C. Thus, microbiological quality of water treated with Moringa oleifera seeds was better than cakes whatever storage temperature and shelf life. Overall, water treated with Moringa oleifera seeds should be stored at low temperature and consumed within 24 hours.

Effectiveness of <i>Moringa oleifera</i>Defatted Cake versus Seed in the Treatment of Unsafe Drinking Water: Case Study of Surface and Well Waters in Burkina Faso

Safe drinking water access for rural populations in developing countries remains a challenge for a sustainable development, particularly in rural and periurban areas of Burkina Faso. The study aims to investigate the purifying capacity of Moringa oleifera defatted cake as compared to Moringa oleifera seed in the treatment of surface and well waters used for populations alimentation. A total of 90 water samples were collected in sterile glass bottles from 3 dams’ water reservoirs, a river, and a large diameter well, respectively. The water samples were treated in triplicate with Moringa oleifera seed and defatted cake coagulants. At different settling time and coagulant concentration, turbidity and pH were measured to determine the optimal conditions and factors influencing treatment with regard to sampling source. Nine physicochemical parameters (turbidity, pH, nitrates, nitrites, calcium, magnesium, total hardness, organic matter and sulfates), three bacterial fecal pollution indicators (Escherichia coli, fecal Coliforms and fecal Streptococcus) and parasite cysts were monitored based on laboratory standard methods. Data were analyzed using the Student’s t test and XLSTAT 7.5.2 statistical software. From the results obtained, for the same concentration of coagulant, settling time providing the lowest turbidity was significantly shorter (p Moringa oleifera cake than seed. Optimum settling time with Moringa oleifera cake was between 15 - 60 min versus 60 - 120 min, with Moringa oleifera seed. Both treatments significantly reduced minerals concentration in water excepted sulfates for which the concentration reversely increased. However, only Moringa oleifera cake treatment reduced organic matter content in all the water samples, while it increased with Moringa oleifera seed one (p < 0.0001). The reduction of microbial pollution indicators was 92% - 100% with M. oleifera cake treatment and 84% - 100% with M. oleifera seed one. Overall, for all water samples, Moringa oleifera cake treatment appeared more efficient in improving drinking water quality than the M. oleifera seed treatment.

Use of Sunflower Cake in the Diet of ISA Brown Pullets

Recently, feed ingredient prices and availability concerns have resulted in the examination of diet formulations using alternative, locally available, high protein feed ingredients. An experiment was carried out to evaluate sunflower cake （SC） dietary effect on the performance of ISA brown pullets. The duration of the experiment was 20 weeks. A total of 48 one-day-old pullets were randomly allocated in three groups （C, SC6.25 and SC12.5） with four replications. The pullets of the control group （C） were given proper full rations without sunflower cake for the 1 st, 2nd and 3rd rearing ages, whereas in the treatment groups 5C6.25 sunflower cake was added at 6.25% of rations and in group SC12.5 at 12.5% of rations. The pullets were housed in floor pens with litter and were offered feed and water ad libitum. According to the results of statistical analysis, the addition of 6.25% sunflower cake in the diet significantly （P 〈 0.05） affected body weight gain and feed conversion ratio. The results of this study showed that sunflower cake can be added to the ration of ISA brown pullets of 0-20 weeks of age up to 12.5% without any adverse effect on their performance.

Tobacco Seeds By-Product as Protein Source for Piglets

Tobacco seed cake is a by-product with interesting characteristics for animal nutrition, due to its high protein content. The focus of this study is to evaluate if tobacco seed cake, administered in feed, can affect principal serum metabolic parameters of weaned piglets in order to establish if it can be used as both a delivery system of edible vaccines and an alternative protein source in piglets diet. A total of 48 weaned piglets were divided in two homogeneous groups for weight, control (CG) and treatment (TG);TG and CG were fed ad libitum with two isoenergetic and isoproteic experimental diets (CP: 17.68% CG and 17.64% TG) differentiated for the inclusion of 4% of tobacco seed cake in the TG diet in replacement of wheat bran and soybean meal. Growth performances were evaluated and feed intake was measured weekly. Blood samples were collected on days 0, 20 and 43 to evaluate hematocrit and principal metabolic parameters, in order to assess the health status of the animals. The administration of tobacco did not impaire health status and growth performance of piglets. The use of bioenergy co-products from non-food crops may represent a good approach creating an integration between biofuel and food production, with consequent benefits for food security and environmental impact.
