Early pregnancy diagnosis in dairy goats and cows was studied using enzyme immunoassays (EIA) to measure progesterone concentrations in whole milk samples collected approximately 3 weeks after mating. Two qualitative on-farm assay kits and 2 quantitative assay kits, all designed for use in the dairy cow, were tested for their accuracy with goats milk samples. Accuracy of diagnosis of goat pregn...

BACKGROUND In this work we aimed at sequencing and assembling the goat milk transcriptome corresponding at colostrum and 120 days of lactation. To reconstruct transcripts we used both the genome as reference, and a de novo assembly approach. Additionally, we aimed at identifying the differentially expressed genes (DEGs) between the two lactation stages and at analyzing the expression of genes i...

Cows' milk--fresh, boiled, and processed in different ways for the domestic market, and various infant milk formulae--was investigated for its sensitising capacity in the guinea-pig after being fed for 37 days. The anaphylactic sensitising capacity was considerably reduced by heat-treatment. As heat becomes more intense and more prolonged so beta-lactoglobulin and casein become less sensitising...

livestock have made major contribution to human societies by providing food, shelter, fuel, and services.  sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in libya.  small ruminant animal meat is popular for libyan customers, and demand is particularly high during religious and cultural festivals.  small ruminants is valued fo...

Anatomical and morphological characteristics of sheep’s mammary gland, their relationship with milk production, milking-ability of the machines and manageability, have become a center of attention among farmers and scientists. Functional traits have become important for efficient breeding schemes in the dairy goat and sheep industries, mainly in Mediterranean countries, due to increased costs o...

THE milk-fats from goats and sheep are used, although only to a small extent, as substitutes for those of cows and buffaloes in India. The component fatty acids and glycerides of these two fats have been studied by methods recently developed [Hilditch et al., 1929; 1930; 1931] in the case of cow butter-fats, in order to compare their composition with those of the latter and, in certain respects...

Milk fat globules memebrane (MFGM)-enriched proteomes from Holstein, Jersey, yak, buffalo, goat, camel, horse, and human were extracted and identified by an iTRAQ quantification proteomic approach. Proteomes data were analyzed by bioinformatic and multivariate statistical analysis and used to present the characteristic traits of the MFGM proteins among the studied mammals. The data of this stud...

POU1F1 is a positive regulator for GH, PRL and TSHβ and its mutations associate with production traits in ruminant animals. We described a DdeI PCR-RFLP method for detecting a silent allele in the goat POU1F1 gene: TCT (241Ser)>TCG (241Ser). Frequencies of D1 allele varied from 0.600 to 1.000 in Chinese 801 goats. Significant associations of DdeI polymorphism with production traits were found i...

Boer and Boer crossbred meat-type does were used in two experiments to determine whether goat milk serum contains leptin and to investigate possible correlations of milk and serum leptin in does and subsequent growth of their offspring. Blood and milk samples were collected within 2 h of kidding (d 0) from 20 (Exp. 1; spring) or 22 does (Exp. 2; the following fall). Blood milk samples were then...
