Cassava By-Products as Feed for Pigs in Burkina Faso: Production Processes, Nutritive Values and Economic Costs

Timbilfou Kiendrébéogo, Nouhoun Zampaligré, Souleymane Ouédraoogo, Youssouf Mopaté Logténé, Chantal Yvette Kaboré-Zoungrana
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 prod

Predation Record of Tropical House Gecko (Hemidactylus mabouia) (Reptilia: Squamata: Gekkonidae) by Guira Cuckoo (Guira guira) (Aves: Cuculiformes: Cuculidae) in the Region of Arraial do Cabo, East Coast of Rio de Janeiro State, Brazil

Marcelo Tardelli Rodrigues, Rodrigo Cumplido, David Steinwender, David Braga Quintanilha, Ubirajara Goncalves de Melo Junior, Patricia de Oliveira Paiva Quintanilha, Luisa Maria Diele-Viegas
The tropical house gecko is an exotic and invasive lizard that has a wide distribution in the New World. Throughout its area of occurrence, the species is predated by several native predators, such as spiders, lizards, snakes, birds, and mammals. The guira cuckoo is a widely distributed bird in South America, usually found in man-impacted regions. The species feeds mainly on arthropods, small vertebrates, and reptiles, such as liz

Records of Southern Sea Lion (Otaria flavescens) (Mammalia: Carnivora: Otariidae) and Total Mercury (THg) Levels in Muscle Tissue of a Specimen on the East Coast of Rio de Janeiro State, Southeastern Brazil

Marcelo Tardelli Rodrigues, Eduardo Barros Fagundes Netto, Rodrigo Cumplido, Ubirajara Goncalves de Melo Junior, David Braga Quintanilha, Eliane Teixeira Mársico, Micheli da Silva Ferreira Ascoli, Carlos Frederico Marques Guimaraes
This study aims to present records of southern sea lions (Otaria flavescens) on the coast of Arraial do Cabo, located on the east coast of Rio de Janeiro State, southeastern Brazil, and information on the levels of total mercury (THg) found in muscle tissue of a specimen collected in the study area. Between July 2003 and February 2017, 5 occurrences of southern sea lions were recorded in the study area. Four of these records were

Climate Variability Adaptation Strategies: Challenges to Livestock Mobility in South-Eastern Burkina Faso

Charles L. Sanou, Daniel N. Tsado, André Kiema, Julia O. Eichie, Appollonia A. Okhimamhe
This research work aims to study the perceptions of pastoralists and agro- pastoralists on climate change impacts on mobile herding and the effectiveness of herders’ adaptive strategies within Kompienga Province, south-eastern region of Burkina Faso. In order to achieve this aim, survey data were retrieved from 271 respondents and analysed. From respondents’ perceptions, climate change is real and is negatively affecting forage av

Risk Factors for Bruises and High Muscle pH in Lamb Carcasses of Tierra Del Fuego, Chilean Patagonia

Juan Antonio Tarumán, Juan Pablo Smulders, Carmen Beatriz Gallo
The aim of the study was to relate some pre-slaughter handling factors for lambs in a slaughterhouse, with the presence of bruises and high muscle pH in carcasses. Stocking density, transport distance and time, and type of slaughter (Conventional or Kosher) were registered in a sample of 1150 lambs that corresponded to 23 loads originated from different farms (Tierra del Fuego, Chilean Patagonia), distance and tim

Temperature Tolerance Test Exposition with Temperate Sea Anemone Actinia equina, a Climatic and Environmental Changes Simulation

Juliana Rodrigues Gadelha, Fátima Jesus, Paula Braga Gomes, Jaime Rendón Von Osten, Fernando Morgado, Amadeu Mortágua Velho da Maia Soares
Atlantic and Mediterranean warming-related diseases outbreaks and species shifts recently have been documented. Evaluated tools of short-term effects on the health or organisms resistance are necessary to assess and understand mechanisms affecting marine biodiversity. Until now, climate warming has been studied at the population or community level. Here we offer a better understanding of such phenomena at the individual organism l

Length-Weight and Some Morphometric Relationships of Valamugil seheli from Sudanese Red Sea Coast

Motasim Ali Mokhtar, Osman Mohammed Farah, Sayed Mohammed Ali
Length-weight relationship is an essential biological parameter needed to appreciate the suitability of the environment for any fish species. That is why many fishery biological studies give an importance to it. The relationships between total length and body depth and girth are very important in estimating the allowable catch and appropriate mesh size to be used in a fishery. Length-weight and some morphometric relationships (depth-total length, girth-total length and dorsal fin length and anal...

A Review on Ruminant Fasciolosis

Mihret Tsega, Samuel Dereso, Addis Getu
This work was conducted to touch the epidemiology and economic impact of ruminants’ Fasciolosis. Ethiopia possesses the largest livestock population in Africa. Ruminants play a significant role in maintaining household stability. However, the productivity per animal and the contribution of this sub-sector to the national economy is relatively low due to multiple factors. The review reveals that Fasciolosis is an important limiting factor for ruminant production and causes for several economic lo...

Breed Characterization: Tools and Their Applications

Addisu Hailu, Addis Getu
During the subsequent history of livestock, the main evolutionary forces of mutation, selective breeding, adaptation, isolation and genetic drift have created an enormous diversity of local populations. Organizing and documentation of basic tools for breed characterization are the major aims of the review with the scope of available markers. This farm animal genetic diversity has a primary requirement to meet current production needs in various environments. In addition, farm animal genetic dive...

The Role of Conformational Traits on Dairy Cattle Production and Their Longevities

Addis Getu, Godadaw Misganaw
The dairy industry faces a unique challenge to constantly improve functionality of the dairy cows to meet the needs of future production and reproduction demands. The basis of improvements is selection of the best animals. The accuracy of selection can be increased by using the combined analysis of both direct information on herd life and indirect information obtained from conformation traits. Generally, conformation traits are important in dairy cattle development. These traits are used ...
