“…Goat milk has high biological value and nutritional qualities due to its higher digestibility and its dietary characteristics with smaller diameter fat globules. It presents a chemical composition composed of proteins of high biological value and essential fatty acids, besides its mineral and vitamin content (Nascimento et al, 2017).…”

Milk is considered as one of the fi nest natural foods containing all the essential nutrients such as lactose, fat, protein, minerals and vitamins in balanced ratio rather than the other foods. The present study was aimed to compare the physicochemical and microbiological qualities of cow, camel and goat milk farmed in Khartoum states. Milk samples were collected from the villages of Khartoum, Sudan and analyzed for nutritional and mineral variations. Our proximate analysis showed that, there was no significant difference (p > 0.05) in total solid content, moisture and fat content of cow, camel and goat milk. However, we found significant differences (p > 0.05) in cow, camel and goat milk for protein content, ash content, total acidity content and pH. In addition to that, mineral analysis of entire samples revealed that level of potassium was highest followed by calcium and phosphorus. However, level of magnesium and zinc was found to be lowest in concentration. Microbiological investigation showed that, total viable count in cow, camel and goat was 3.5  10 3 , 7.5 10 3 and 4.5 10 3 , respectively. Moreover, total coliform count was found to be 9, 7 and 6 in cow, camel and goat respectively count indicates possible poor hygienic practices at farm level. In addition to that, Yeast and Mold, Staphylococcus aureus, Escherichia coli and Salmonella was not detected in the samples. This work provides updated information on the current physicochemical and microbiological characteristics of cow, camel and goat milk collected from the farms of Khartoum, Sudan. This can be of great importance in the fi elds of dairy, food technology and food analysis.

RESUMO Objetivou-se, com este estudo, avaliar o efeito de dietas com diferentes níveis de energia no consumo de nutrientes, na produção e na composição do leite, no peso corporal e na relação benefício:custo de uma produção de cabras leiteiras. Foram utilizadas nove cabras, distribuídas em quadrado latino triplo 3 x 3. O ensaio teve duração de 60 dias, divididos em três períodos de 20 dias. Avaliaram-se rações completas contendo três níveis de energia: 65%, 70% e 75% de NDT. Os consumos de matéria seca, proteína bruta e matéria mineral foram superiores (P<0,05) nas dietas com maiores níveis de energia em comparação à dieta com 65% de NDT. A produção de leite foi semelhante (P>0,05) nas cabras recebendo dietas contendo 70% e 75% de NDT, todavia foi superior (P<0,05) à produção de leite das cabras recebendo dieta com 65% de NDT. A dieta com 75% de NDT possibilitou maior (P<0,05) peso corporal final, quando comparada com as dietas contendo 65% e 70% de NDT. Não foi observada diferença (P>0,05) para os parâmetros físico-químicos de gordura, lactose, proteína bruta, extrato seco desengordurado, densidade, sais e condutividade do leite. Portanto, cabras alimentadas com níveis de energia entre 70% e 75% de NDT na dieta total aumentam a produção de leite, porém 75% de NDT na dieta proporciona melhor relação benefício:custo, havendo, para cada R$ 1,00 no custo investido na alimentação, R$ 1,52 de retorno financeiro.
