Resumo: A caprinocultura de leite tem sido apontada como uma alternativa econômica para as pequenas propriedades rurais, sendo que a produção de queijo pode aumentar a lucratividade devido ao valor agregado ao produto. No entanto, os animais apresentam uma estacionalidade produtiva, ou seja, em alguns períodos há abundância e em outros, escassez de leite. O congelamento do leite ou de coalhadas dessoradas para a produção de queijo consiste numa alternativa para contornar o problema. O objetivo do trabalho foi avaliar um queijo obtido de massa mole com coagulação mista, maturado pelo fungo Penicillium candidum utilizando-se leite congelado pelos processos lento (freezer comum) ou rápido (nitrogênio líquido) e a fabricação do mesmo queijo utilizando-se coalhada dessorada e congelada pelos mesmos processos. Verificou-se que os queijos resultantes do congelamento do leite e congelamento da coalhada pelos processos lento e rápido não diferiram dos queijos controle (sem congelamento) quanto ao rendimento, características físico-químicas, composição e aspectos microbiológicos, mesmo quando comparados aos resultados obtidos na matéria seca do queijo.
[Chemicophysical and microbiological aspects of cheese made of a mixed coagulation, ripened by mould using slow or fast frozen goat's milk and slow or fast frozen curd].
Abstract: Milk goats are indicated as an economic alternative for small farmers and cheese making could improve their profits. Goat's milk has a seasonal production characteristic and shows periods of abundance and others of scarcity. The use of frozen milk or frozen curd to make cheese can be used to solve the problem. The aim of this work was to evaluate the preparation of cheese made from mixed curd and ripened by Penicillium candidum mould using slow frozen milk (in a domestic freezer) or fast frozen milk (by liquid nitrogen). The slow frozen curd and fast frozen curd without whey were used. It was observed that the cheese from the slow and fast frozen milk and from the slow and fast frozen curd did not differ from the control cheese for the yield, chemicophysical characteristics, chemical composition, extention ripened rate, depth ripened rate and microbiological aspects, even when it was expressed as a dry matter content of cheeses.

Conjugated linoleic acids (CLA) are potent anticarcinogens in animal and in vitro models as well as inhibitors of fatty acid synthesis in mammary gland, liver, and adipose tissue. Our objective was to evaluate long-term CLA supplementation of lactating dairy cows in tropical pasture on milk production and composition and residual effects posttreatment. Thirty crossbred cows grazing stargrass (Cynodon nlemfuensis Vanderyst var. nlemfüensis) were blocked by parity and received 150 g/d of a dietary fat supplement of either Ca-salts of palm oil fatty acids (control) or a mixture of Casalts of CLA (CLA treatment). Supplements of fatty acids were mixed with 4 kg/d of concentrate. Grazing plus supplements were estimated to provide 115% of the estimated metabolizable protein requirements from 28 to 84 d in milk (treatment period). The CLA supplement provided 15 g/d of cis-9,trans-11 and 22 g of cis-10,trans-12. Residual effects were evaluated from 85 to 112 d in milk (residual period) when cows were fed an 18% crude protein concentrate without added fat. The CLA treatment increased milk production but reduced milk fat concentration from 2.90 to 2.14% and fat production from 437 to 348 g/d. Milk protein concentration increased by 11.5% (2.79 to 3.11%) and production by 19% (422 to 504 g/d) in the cows fed CLA. The CLA treatment decreased milk energy concentration and increased milk volume, resulting in unchanged energy output. Milk production and protein concentration and production were also greater during the residual period for the CLA-treated cows. The CLA treatment reduced production of fatty acids (FA) of all chain lengths, but the larger effect was on short-chain FA, causing a shift toward a greater content of longer chain FA. The CLA treatment increased total milk CLA content by 30% and content of the trans-10,cis-12 CLA isomer by 88%. The CLA treatment tended to decrease the number of days open, suggesting a possible effect on reproduction. Under tropical grazing conditions, in a nutritionally challenging environment, CLA-treated cows decreased milk fat content and secreted the same amount of milk energy by increasing milk volume and milk protein production.
