Milk yield and composition data from 7 nursing Lusitano mares (450 to 580 kg of body weight and 2 to 9 parities) were used in this study (5 measurements per mare for milk yield and 8 measurements for composition). Wood's lactation model was used to describe milk fat, protein, and lactose lactation curves. Mean values for the concentration of major milk components across the lactation period (18...

AIM To study the alteration of major milk components such as milk fat, protein, lactose, solid not fat (SNF) and total solids (TS) and their association with different degree of intra-mammary inflammation (IMI) in Jaffrabadi buffaloes. MATERIALS AND METHODS Milk samples (n=1516) were collected from Jaffrabadi buffaloes separately from each quarter. Milk samples were analyzed for milk fat, pro...

Milk is a very complex nutrient and differs significantly between species. Monotreme Marsupial milk contains only trace amounts of lactose, whereas in Eutherian species, lactose the predominant saccharide. Within Eutheria, composition varies from 8.5% Indian rhinoceros to 63.8% Grey seal concentration; 0.3% 9.3% elephants total fat; 1.2% 12.8% Fin whale protein; finally 0.8% Great panda 6.5% la...

The lactose transport protein (LacS) of Streptococcus thermophilus is composed of a translocator domain and a regulatory domain that is phosphorylated by HPr(His approximately P), the general energy coupling protein of the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). Lactose transport is affected by the phosphorylation state of HPr through changes in the activity of the Lac...

Lactose is the only soluble and economically feasible carbon source for the production of cellulases or heterologous proteins regulated by cellulase expression signals by Hypocrea jecorina (Trichoderma reesei). We investigated the role of the major beta-galactosidase of H. jecorina in lactose metabolism and cellulase induction. A genomic copy of the bga1 gene was cloned, and this copy encodes a...

In patients with a cow’s milk protein allergy, the presence of these allergens in medicines, even trace amounts, can trigger serious allergic reactions. The study milk-related excipient prevalence 165 antiasthmatic based on information included Summary Product Characteristics, revealed lactose more than one third medicines. Since may suffer cross-contamination protein, results are an alert to h...

Abstract Purpose The growth behavior of novel fungal isolates along with the production bioactive compounds from mycelia mass during submerged fermentations were investigated using conventional synthetic media and agro-industrial residues as fermentation substrates. Methods Four isolated fungi, belonging to edible or medicinal species, evaluated for their ex-situ on potato dextrose agar. Specif...

ABSTRACT This study aimed to determine the impact of different post-partum disorders on milk yield and composition. One hundred fifteen Holstein cows from a commercial dairy farm located in state Rio Grande do Sul southern Brazil were monitored up 62 days post-partum. During this period, body condition score evaluation animal clinical examination conducted. Percentages fat, protein, lactose, as...

The objective was to study the cause of variation in digestibility of mixed linked β(1-3;1-4)-D-glucan (β-glucan) in the small intestine of growing pigs. The β-glucan is an important cell wall [dietary fiber (DF)] component of the endosperm of barley (Hordeum vulgare) and oats (Avena sativa). The digestibility of β-glucan in the small intestine from both cereals is among the highest of all DF c...

Lactose is the only soluble and economically feasible carbon source for the production of cellulases or heterologous proteins regulated by cellulase expression signals by Hypocrea jecorina (Trichoderma reesei). We investigated the role of the major -galactosidase of H. jecorina in lactose metabolism and cellulase induction. A genomic copy of the bga1 gene was cloned, and this copy encodes a 1,0...
