“…O pós-dipping era realizado com iodo em 5/6 (83,4%) dos capris leiteiros, porém um dos capris examinados não adotava essa medida. É válido ressaltar que o uso de iodo no pré-dipping pode gerar resíduos no leite, decorrente da contaminação da superfície do teto ou absorção do produto e eliminação durante o processo de síntese da secreção láctea (FLACHOWSKY et al, 2014 Fonte: Elaboração dos autores.…”

ResumoO objetivo do trabalho foi identificar os agentes etiológicos e fatores de risco para a mastite carpina. Para tanto, foram colhidas duas alíquotas de 257 amostras de leite, nos meses compreendidos entre Abril a Setembro de 2012, provenientes de 136 cabras da raça Saanen, oriundas de seis criações intensivas, com sistema de ordenha manual e mecânica, localizadas no estado de São Paulo. A primeira alíquota das amostras de leite foi obtida em frascos contendo o conservante bronopol para a contagem de célula somática (CCS) eletrônica, e a segunda em frascos estéreis para o exame bacteriológico. Para avaliação dos fatores de risco, foram aplicados questionários epidemiológicos preenchidos pela equipe de pesquisa mediante observações visuais e inquérito com tratadores e proprietários. Foram realizadas análises univariada e multivariada, utilizando-se a regressão logística múltipla. Observou-se prevalência de 28,79% de infecção mamária com predomínio de Staphylococcus coagulase negativa (SCN). A mediana da CCS obtida foi de 4,7x10 5 células por mL (céls mL -1 ) de leite. Na análise univariada foi possível observar risco para a infecção mamária nos locais onde a caprinocultura não era a atividade principal da propriedade (p=0,03); a prova do fundo escuro não era realizada (p=0,07); não era utilizado o cloro na limpeza dos tetos (p=0,29); realizava-se limpeza inadequada da sala de ordenha (p=0,06); observou-se higiene inadequada no processo de ordenha (p=0,03) e a higiene do ordenhador era inadequada (p=0,03). A higiene dos tetos, da sala, do processo de ordenha e ordenhador foram os maiores riscos associados à infecção mamária por SCN. Desta forma, apesar das indicações de medidas higiênicas nos programas de qualidade do leite e controle de mastite, a aplicabilidade e conscientização do pessoal envolvido com a cadeia produtiva ainda não estão sensibilizadas. Assim, o treinamento de pessoal seria a principal medida recomendada para o controle da mastite em cabras leiteiras.

“…Several factors influence the iodine content of cow's milk, such as the level of iodine supplements in feed, some iodine antagonists (such as glucosinolates) in the feed, or the farm management. The frequent practice of using mineral mixtures containing iodine in conventional farming is one of the reasons for the higher iodine content in conventional milk [45].…”

Abstract:The organic food market is considerably expanding all over the world, and the related dairy market represents its third most important sector. The reason lies in the fact that consumers tend to associate organic dairy products with positive perceptions: organic milk is eco-and animal-friendly, is not produced with antibiotics or hormones, and according to general opinion, provides additional nutrients and beneficial properties. These factors justify its higher cost. These are the reasons that explain extensive research into the comparison of the differences in the amount of chemical compounds between organic and conventional milk. However, it is not simple to ascertain the potential advantage of organic food from the nutritional point of view, because this aspect should be determined within the context of the total diet. Thus, considering all the factors described above, the purpose of this work is to compare the amount of selected nutrients (i.e., iodine and the fat-soluble vitamins such as alfa-tocopherol and beta-carotene) in organic and conventional milk, expressed as the percentage of recommended daily intakes in one serving. In detail, in order to establish the real share of these biologically active compounds to the total diet, their percent contribution was calculated using the Dietary Reference Values for adults (both men and women) adopted by the European Food Safety Authority. According to these preliminary considerations, the higher cost of organic milk can mainly be explained by the high costs of the management of specific farms and no remarkable or substantial benefits in human health can be ascribed to the consumption of organic milk. In this respect, this paper wants to make a small contribution to the estimation of the potential value and nutritional health benefits of organic food, even though further studies are needed.

“…Goat excrete the iodine in the milk is higher than other ruminant species (Flachowsky et al, 2014). Nudda et al (2009) stated that iodine excreted through dairy cattle milk was 2% but in goat could reach 94% from iodine consumed daily.…”

Abstract. The objective of the study was to determine the iodine status and to map the thyroxin hormone concentration in etawah crossbred goat (ECG) at different physiological stages and its interrelation to the nutrition and performance. Fifteen female ECG was allotted in three physiolgical stage groups: female kid, young female goat and lactating goat, fed elephant grass and tofu byproduct. The study was conducted in Tossa Shakti Agro Company (TSA), Central Java, Indonesia. Analysis of variance in completely randomized design was used to determine the effect of physiological stages on soil and feed iodine content, blood serum thyroxin hormone concentration, nutrient and feed dry matter consumption, average daily gain and milk production. Result showed that soil iodine content was adequate to stimulate plant growth (3.109 mg/kg). Consumed feed iodine content was adequate to all physiological stages, female kid, young female and lactating goat (1.003; 0.940 and 0.820 mg/kg, respectively). Thyroxin hormone concentration in blood serum of female kid and young female goat was in normal range (8.23 and 10.05 µg/dl) but the concentration of thyroxin hormone in blood serum of lactating goat was marginal ( 6.17 µg/dl). Iodine supplementation was required for lactating etawa crossbred goat if tofu byproduct was included in its ration. Key words : nutrient, iodine, thyroxin hormone, etawah crossbred goatAbstrak. Penelitian ini bertujuan mengkaji status iodine dan memetakan konsentrasi hormone tiroksin kambing peranakan etawah (PE) pada berbagai status fisiologis dan interelasinya dengan status nutrisi serta performans ternak. Sebanyak 15 ekor kambing PE betina digunakan dalam penelitian yang terbagi atas tiga kelompok status fisiologis, yakni: cempe betina, kambing dara dan kambing laktasi. Sebagai pakan, digunakan rumput gajah dan ampas tahu. Penelitian ini dilakukan di PT. Tossa Shakti Agro (TSA) Kendal, Jawa Tengah. Variabel yang diukur meliputi kandungan iodin tanah dan pakan, kadar hormon tiroksin serum darah, konsumsi bahan kering pakan dan nutrien, pertambahan bobot badan serta produksi susu. Data yang terkumpul diolah secara statistik dengan analisis variansi dalam rancangan acak lengkap guna mengetahui pengaruh status fisiologis terhadap variable-variabel tersebut. Hasil penelitian menunjukkan bahwa kandungan iodine tanah memadai untuk menstimulasi pertumbuhan tanaman (3,109 mg/kg). Kandungn iodin pakan terkonsumsi memadai untuk semua status fisiologis, dalam hal ini cempe betina, kambing dara dan kambing laktasi (masing-masing: 1,003; 0,940 dan 0,820 mg/kg). Konsentrasi hormon tiroksin serum darah cempe betina dan kambing dara dalam kisaran normal (8,23 dan 10,05 ug/dl), tetapi konsentrasi hormon tiroksin serum darah kambing laktasi berada pada batas normal (borderline), yakni 6,17 ug/dl. Suplementasi iodin diperlukan bagi kambing peranakan etawa yang sedang laktasi, jika ampas tahu digunakan sebagai bagian dari ransum.
