Neospora caninum is considered to be one of the main causes of abortion among cattle. The present survey was conducted in the municipality of Rolim de Moura, Rondônia State, Brazil. A questionnaire that investigates the epidemiological aspects of neosporosis was used in the analysis of risk factors associated with the animal-level and herd-level prevalence in dairy cattle. A total of 416 bovine blood samples were collected from 30 farms, and N. caninum antibody levels were measured by Indirect Fluorescent Antibody Test (IFAT). Analysis of dairy cattle serum samples revealed the presence of anti-N. caninum antibodies to be 47.36% (n = 197). Risk factors associated with N. caninum infection were the management system and access locations of dogs. The results of the present survey indicated that infection of dairy cattle with N. caninum is widespread in the studied region of Western Amazon, which has implications for prevention and control of neosporosis in this region. Therefore, integrated control strategies and measures are recommended to prevent and control N. caninum infection in dairy cattle. In addition, direct contact between dairy cattle, dogs and wild animals, which can influence the epidemiology of neosporosis, should be investigated further.
RESUMOObjetivou-se avaliar o consumo, a digestibilidade e o desempenho de ovinos, arraçoados com dietas isoproteicas, contendo 75% de resíduos da agroindústria frutífera (abacaxi, acerola, maracujá e cupuaçu), uma dieta com feno de tifton e 25% de concentrado, em delineamento inteiramente ao acaso. A participação do resíduo de maracujá na dieta proporcionou os maiores níveis de consumo de matéria seca (1170,6g d -1 ) em relação aos resíduos de abacaxi (693,8g d -1 ), acerola (644,2g d -1 ), cupuaçu (452,9g d -1 ) e feno de tifton (962,7g d -1 ), o que se relaciona aos seus níveis de digestibilidade (77,8; 63,1; 59,1; 61,7 e 71,8%, respectivamente). Tal resultado gerou diferenças significativas, destacando-se o resíduo de maracujá quanto à conversão alimentar (8,3), e o ganho médio diário de peso (141,5g d -1 ). Apesar de ter tido a mesma conversão observada para o feno de tifton (13,2), apresentou maior ganho médio diário (75,6g d -1 ). Os demais resíduos apresentaram efeitos sobrepostos, contudo o resíduo de acerola ficou com a pior conversão (51,4) e o menor ganho médio diário (15,6g d -1 ), sendo esse sem diferença em relação ao cupuaçu (23,0g d -1 ). Os resíduos podem ser utilizados como alternativa para a alimentação de ovinos.Palavras-chave: abacaxi, acerola, cupuaçu, maracujá, subprodutos ABSTRATThe objective was to evaluate the consumption, digestibility and performance of the sheep with iso protein diets, with 75% of residues from fruit agro-industries (pineapple, acerola, passion fruit, and cupuassu) and a diet with tifton hay, and 25% of concentrate, in a totally randomized design. The participation of passion fruit residue on the diet provided the highest consumption levels of dry matter (1170.6g d -1 ) compared with the residues of pineapple (693.8g d -1 ), acerola (644.2g d -1 ), cupuassu (452.9g d -1 ) and tifton hay (962.7g d -1 ), which is related to their levels of digestibility (77.85, 63.14, 59.07, 61.68 and 71.83%, respectively). Such a result generated significant differences with emphasis on passion fruit residue regarding food inversion (8.30) and average daily weight gain (141.50g d -1 ), in spite of having the same conversion detected for tifton hay (13.2), it showed a higher average daily gain (75.6g d -1 ). The other residues showed overlapping effects, however, acerola residue showed the worst conversion level (51.4) and the lowest average daily gain (15.6g d -1 ), and this one showed no difference compared with cupuassu (23.0g d -1 ). The residues can be used as an alternative for sheep feeding.
The process of production of silage from fish waste may represent an important source of protein and energy for broilers, and rationally allocate this residue which is normally discarded erroneously. This work aimed to evaluate weight gain and morphometric parameters of broilers fed with feed made from fish viscera silage. For the composition of the experimental diet was counted with: 65.61 % of the silage fish waste, 30.39 % soybean meal, 2.20 % of calcined bone meal , 1.40 % soda and 0 , 30% vitamin mineral premix , in order to provide levels mixture of 19.2 % CP 0.898 % Ca, 0.528% P disp. and 3874 kcal kg- 1 of EB. However, during the experimental period the broilers they had died. In another experiment involving non-nutrient additives, but using the same source of silage, had same result. It is suspected that the level of conservation of raw material can be related to the case on the basis of having the potential to produce biogenic amines.
Avaliou-se o emprego de silagem ácida de vísceras de tambaqui para alimentação de cães jovens. As variáveis estudadas foram o estado geral, o ganho de peso vivo, o escore corporal e fecal, a consistência e odor das fezes e a função hepática e renal dos animais. A ração foi composta com 46% de silagem e calculada para gerar níveis nutricionais iguais aos registrados no rótulo da ração comercial para filhotes e compatível com a recomendação para a idade dos animais, ou seja, 26% PB, de 1,0 a 2,0% de Cálcio, 0,9% de Fósforo e 3295 kcal kg-1 EM. O período experimental foi de 52 dias sendo que as amostras de sangue, para avaliação bioquímica, foram coletas no 53º dia após o jejum de 12 horas. O uso da silagem na alimentação dos cães foi satisfatório não diferindo em relação a todas as variáveis estudadas, em relação ao grupo controle. Este estudo, de caráter exploratório, gera o indicativo de uso da silagem de resíduos de peixes a ser empregado como fonte protéica na formulação de ração para cães.
