Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105711
Introduction: In Burkina Faso, as in many countries in sub-Saharan Africa, the low availability and high cost of feed is the main limiting factor for pigs’ productivity. While cassava byproducts are well known and used in many countries to overcome this constraint, very little is known on its uses as feed in Burkina Faso. Objective: The study aims to develop processes for the production of pig feeds from cassava leaves and by products (peelings and residues of sieving for gari making). Experimentations: Some cassava leaves, peelings and residues of sieving gari were collected, sun-dried and milled (peels and residues) or mortared (leaves). The dry matter contents were 88.89%, 90.83% and 91.67% respectively for food of cassava peeling (FCP), leaves (FCL), and gari sieving residues (GRSF). The crud protein (CP) contents were 28.87% for FCL, 4.22% for FCP and 1.72% for GRSF. Crude fiber (CB) and ADF were 15.98% and 30.6% for FCP, 15.79% and 23.29% for FCL and 3.27% and 4.45% for GRSF. The NDF content of FCL (45.32%) was higher than the FCP (38.36%) and GRSF (18.42%) feed respectively. Lignin levels were more important in FCP than in FCL and GRSF. The digestible energy (DE) contents were 2424 kcal for FCL, 2683 kcal for FCP and 3471 kcal DE for GRSF. The production costs of a kg of Dry Matter (DM) of FCP were 15 FCFA, FCL were 101 FCFA and 150 FCFA for GRSF. Conclusion: Pig’s feed production based on cassava by-products in Burkina Faso is a good opportunity to make feed more available at reduced cost. Further research is needed to assess pigs zootechnical performances and cost benefits of pig’s diets with these feeds.

Agricultural Sciences (AS) , 2016, DOI: 10.4236/as.2016.74025
Abstract: This article couples an examination of grain production with Virginia’s livestock and poultry sector to analyze the overall magnitude and distribution of grain consumption in Virginia. Specifically, this paper describes the sources and trends over time of grain production and consumption; identifies grain surplus (and deficit) areas across Virginia’s counties; describes and applies a methodology to quantify livestock and poultry consumption requirements at the state- and county-levels; provides an updated assessment of Virginia’s ability to meet its feed grain needs; and discusses implications on the overall distribution system. Important results of the analysis reveal that grain consumption in Virginia is due mainly to demand in the poultry sector (primarily broilers and chickens). Furthermore, grain consumption in this state has generally declined over the last twenty years, due to decreasing livestock population numbers. Coupled with a slight upward trend in grain production, Virginia appears to be increasingly capable of meeting its grain needs. There is, however, an important east-west divide in the state, with western counties requiring more grain than they produce. Since grain does not appear to move from the relatively “production-rich” eastern counties, transportation infrastructure is important to bring in grain from outside the state.

Abstract: the objective of this study was to find an alternative to minimize environmental contamination by leather waste using it as ruminant feed. the wet blue leather wastes (wb) without chrome extraction were compared with the leather wastes in which the chrome was extracted (ce). both materials had 99.7% of dry matter (dm), but the crude protein level was higher (90.4%) in ce than in wb (74.3%). in situ effective ruminal degradability of dm was 59.7% and it was 63.1% for cp in ce. the wb did not suffer degradation in the rumen. in vitro abomasal digestibility of ce was 100%. the percentage of degradation per hour was higher for ce (8.2%) than for wb (0.08%). the mineral content was higher in wet blue leather wastes (10.4%) than in ce (0.4%) reflecting the chrome level and demonstrating that the removal process of this mineral is efficient. the use in animal feed is presented as a viable alternative for the disposal of waste and scrap generated by the leather tanning industry and treated by the extraction method, thus minimizing environmental contamination and providing a source of protein for animal feed.

Abstract: Mycotoxins, as secondary metabolic products of molds, are common contaminants of raw feed materials and compound feeds. Depending on the agro-meteorological and storage conditions, molds can contaminate grains and produce mycotoxins in the field, before and after harvest and during storage. Way of preventing animal mycotoxicoses and transfer of mycotoxins to humans through food chain is regular inspection on mycotoxicological feed safety. This paper presents the results of examination of aflatoxin, ochratoxin and zearalenone in 89 samples tested under laboratory conditions during a one year period. The analyses of types of samples, contamination, and their origin demonstrated the need for preventive control of mycotoxin content, primarily in grains. The results of testing the content of aflatoxin in milk indicate the existence of risks to human health. In order to protect humans and animals from mycotoxicological contamination, we propose the use of the system hazard analysis and critical control point (HACCP), which has been proved to be an effective strategy in food safety control. The basic principles of HACCP approach in the production of feed and foodstuffs, as well as the compliance and harmonization of legislations with those in the European Union, in the field of mycotoxicological tests, are the best prevention against mycotoxin effects on health and economy. Implementation of HACCP system currently presents one of the basic preconditions for the export of our products and their placement on the European market.

Abstract: This paper shows the results of screening of mycotoxins in animal feed originating from the region of Vojvodina. Permanent screening is needed on all levels of production and storage, as well as the use of known methods to reduce mould contamination or toxin content in feedstuffs and feed. A total of 56 representative samples were collected from feed companies from the region of Vojvodina. Samples were collected during February 2009. The collected samples included 41 samples of feedstuffs (soybean, soybean meal, soybean grits, soybean cake, maize, sunflower meal, barley, wheat feed flour, rapeseed meal, dehydrated sugar beet pulps, alfalfa meal, yeast, dried whey, fish meal, meat-bone meal) and 15 samples of complete feedingstuffs. The amounts of aflatoxins, ochratoxin A, zearalenone, fumonisin and deoxynivalenol were determined. Screening method for the analysis was done using Neogen Veratox testing kits. The test itself is a competitive direct enzyme-linked immunosorbent assay (CD-ELISA). Mycotoxins were present in 71.4% of the samples, but the values determined were below the maximum allowed limits for both Serbian and EC reference values. Zearalenone was found with the highest incidence (57.1% of samples), followed by ochratoxin A (37.5%), fumonisin (33.9%), deoxynivalenol (14.3%) and aflatoxins (3.6%).
Potential Value of Acridids as High Protein Supplement for Poultry Feed
Hena Anand,Arijit Ganguly,Parimalendu Haldar
International Journal of Poultry Science , 2008,
Abstract: It is well known that acridids are an attractive and important natural source of food for many kinds of vertebrate animals, including birds, lizards, snakes, amphibians, fish and other mammals. Despite that they drew very few research attentions as feed for domesticated animals, particularly poultry, swine and freshwater fish. In the present study energy estimation and proximate analysis were conducted for four acridid species in order to determine the nutritional quality of those species and their potential value as an alternative animal protein source. The experiment revealed acridids to have a higher amount of protein content in compared to the conventional soybean and fish meals. A high amount of caloric contents were also evident in the chosen acridids. The most important conclusion of this study was that the acridids can provide a reliable and sustainable source of high quality animal protein for domesticated animals.

Félix Hernández, Miguel Hernández-Campos
Smart Grid and Renewable Energy (SGRE) , 2011, DOI: 10.4236/sgre.2011.22013
Abstract: This article examines the development of the four main renewable energy technologies (RET) in Spain in the latest years: biomass, small hydro (SH), solar photovoltaic (solar PV) and wind. It has been studied the variation of the work-ing time per MW installed available from the on line data base of Spanish National Commission on Energy (SNCE), in the national context and in each of the Autonomic Communities (AACC). We have also obtained the marginal cost curve of the global RE. The main conclusions of the study are that Spain is effective meeting the RE generation target but not efficient in costs and in short term it is not any RETs that can achieve competitive price comparing to the elec-trical market.
