Of particular concern is saprolegniasis, which is an infectious fungal disease that is widespread in all stages of the life cycle of fish. The disease causes serious losses in fish farms and hatcheries, especially among salmonid species. The initial clinical sign was characterized by the growth of cotton-like mycelia on the body surface, especially the head, adipose fin, and caudal fin, but the mycelia were not visible to the naked eye in the internal organs. The overall aims of this study are to gain a clearer understanding of the incidence and prevalence of saprolegniasis especially among salmonid fishes in Japan. Therefore, the author attempted to work on the objectives to investigate the Saprolegnia species associated with fungal infection in salmonids, with the goal of finding additional taxonomic criteria for such pathogenic species. Moreover, special efforts were done to develop devices for control of such infection either by using antifungal agents as substitute for malachite green and formalin or by biocontrol technique. ····· 1036192593

Goat milk and its products are known for its properties regarding the health benefits. There are 34.0 million goats in Bangladesh and Black Bengal goats make up more than 90% which is famous for meat and skin in the world. But their production is not sufficient that is why a few private farmers are initiated cross breeding between the exotic buck (Beetal, Sirohi and Jamunapari) and doe of Black Bengal. The experiment was conducted at private and government buck breeding centres of Rajshahi, Bangladesh during January, 2009 to October, 2010 to evaluate the phenotypic traits of 60 bucks, namely Jamunapari (n=9), Sirohi (n=15), Beetal (n=13), Crossbred (n=13) and Black Bengal (n=10) and the status of reproductive and productive (RP) performance in 777 doe belonged to Jamunapari cross (n=163), Sirohi cross (n=66), Beetal cross (n=80) and Black Bengal (n=468). It is concluded that for cross breeding, the performance had superior in Beetal Jamunapari Sirohi crossbred Black Bengal buck as well as the overall RP performance had better in SirohiBeetalJamunapariBlack Bengal doe. ····· 1036192581

The sheep in Bangladesh are mainly utilized for meat purposes but also important for good quality leathers and source of income to rural people. One of the infectious diseases, which are a major constraint for sheep productivity, is brucellosis. It is a widely spread disease in the developing countries caused by six species of the bacterial genus Brucella. Bangladesh has been reported as an endemic country for brucellosis because of a considerable number of human and animal populations are exposed to the infection each year. Most cases of brucellosis infection in sheep are inapparent and lack clinical signs. The first evident manifestation is abortion,which frequently occurs 3 to 4 months after gestation. Clinical signs of infected rams are orchitis, hogbacks, anorexia, emaciation, and gradual loss of capacity for hybridization. Other symptoms also include mastitis, bronchitis, and arthritis, among others. This book illustrates the serological diagnosis and epidemiology of brucellosis in sheep and shows a new way of developing the sheep industry. ····· 1036191475

Se reproducen bien, crecen rápido, aprenden rápido y se adaptan a una gran variedad de condiciones locales.

Como resultado de esto, se ha podido incrementar con éxito, el progreso genético de los hatos (rebaños y rodeos), destinados a la producción de leche, carne y lana, a través de las diferentes tecnologías aplicadas comercialmente desde mediados del siglo XX. Dichas técnicas tienen importancia per se y pueden ser empleadas, además, como herramientas en el desarrollo de otras más modernas. Aquí se utiliza la transferencia nuclear como la biotecnología que permite, en forma asexual, la producción de un organismo genéticamente idéntico al material nuclear con el que se generó. La transgénesis es la introducción de genes exógenos a un organismo, otorgándole caracteres nuevos de interés humano. Adicionalmente es una técnica que depende de herramientas como la genética, biología molecular y reproducción animal. Los análisis de genómica funcional en vertebrados, incluyendo peces, anfibios y ratones, han contribuido a comprender los procesos de desarrollo embrionario así como determinadas enfermedades humanas. ····· 1036191063

En años recientes se ha demostrado que los ácidos grasos poliinsaturados tienen el mayor impacto sobre el desempeño animal, particularmente los ácidos grasos conocidos como Omega 3 y 6. Al utilizar fuentes de grasa protegidas o sobrepasantes, es posible disminuir notablemente la biohidrogenación ruminal de los Omega 3 y 6, incrementando su disponibilidad a nivel intestinal y por ende su absorción. Los efectos positivos de los ácidos grasos poliinsaturados van más allá del efecto energético per se, éstos pueden tener efectos benéficos directos sobre la actividad productiva y reproductiva, mejorando la producción de leche, la condición corporal, la actividad ovárica, la involución uterina, la tasa de preñez, de concepción, entre otros.

Trypanosoma vivax and T. congolense were the species of trypanosome investigated during the study period. Both cyclical (Glossina morsitasns submorsitans) and non-cyclical (Tabanus, Stomoxysis and others) vectors of trypanosomes were identified. The prophylactic and curative doses of trypanocidal drugs locally used by farmers were found to be poor efficacy based on field methods of drug resistance detection indicating the presence of drug resistance. There was seasonal varation in the prevalence of trypanosomosis and fly density with higher prevalenc e and higher fly density just after rainy season than during the dry period. Therefore integrated and stratagic control program against the parasite and the vector is essential for improved productivity of livestock and agricultural activities in the study areas. ····· 1036188778

It is an important cause of abortion, stillbirth and neonatal mortality in sheep and goats. The parasite is transmitted to human mainly by ingesting food or water contaminated with oocysts shed by cats or by eating undercooked or raw meat containing tissue cysts. All mammals, including man and birds are intermediate hosts, whereas Felidae act both as intermediate and definitive hosts. Therefore, it is particularly beneficial to ensure the prevalence of this parasite in animal species destined for human consumption. Results of the current study will be helpful in developing appropriate countermeasures against Toxoplasmosis in human beings. ····· 1036188766· 1 · ::::: · 5 ·· 6 ·· 7 ·· 8 ·· 9 ·· 10 ·· 11 · ::::: · 13 ·
