The objective of the present study was twofold: first to compare the degradation patterns of caprine whey proteins digested with either human digestive juices (gastric or duodenal) or commercial porcine enzymes (pepsin or pancreatic enzymes) and second to observe the effect of gastric pH on digestion. An in vitro two-step assay was performed at 37 degrees C to simulate digestion in the stomach ...

Among the toxins that Staphylococcus aureus is able to secrete, bi-component toxins named leukotoxins target specifically leukocytes, mainly phagocytic cells. Isolates from cows, goats and ewes with mastitis were selected on the basis of the presence or not of the genes encoding the recently described LukM/LukF'-PV leukotoxin. Of the 128 isolates tested, 126 had moderate to high leukotoxic acti...

A serological survey of brucellosis was carried out in three selected local government areas of Taraba state to determine the current status of the disease in the field, especially in the nomadic Fulani breeding herds. A test using the Brucella abortus Rose Bengal Plate Test antigen to test the sera of bovine, ovine and caprine for presence of Brucella abortus antibodies and Milk Ring Test anti...

Peptides in caprine whey were identified after in vitro digestion with human gastrointestinal enzymes in order to determine their antibacterial effect. The digestion was performed in two continuing steps using human gastric juice (pH 2·5) and human duodenal juice (pH 8) at 37°C. After digestion the hydrolysate was fractionated and 106 peptides were identified. From these results, twenty-two pep...

The present study was planned with the objective to amplify 5’NCR Insulin-like growth factor 1 (IGF1) and 3’UTR Prolactin receptor (PRLR) genes using caprine specific primers by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in Surti Mehsana goats. IGF1 gene found be monomorphic on restriction digestion HaeIII, which revealed only one genotype GG both allele frequ...

the aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(cphv-1) and their application for cphv-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. cphv-1 hemagglutination activity was proved only with mouseerythrocytes, pbs and saline solutions at 4°c and 22°c. in vaccinated animals, goats and bucks withresp...

Whey from goat and sheep have been gaining attention in the last few years for their nutritional properties. Unfortunately, β-Lg, not found human milk, may trigger infant allergies if used food formulations, so there is a growing interest developing ingredients derived whey with higher α-La/β-Lg ratios. The objective of this work was to study effect high-pressure processing (HPP) on caprine ovi...

toxoplasmosis, caused by toxoplasma gondii (t. gondii), is an economically important disease of livestock, especially sheep and goats, where it can cause early embryonic death and resorption, fetal death and mummification, abortion, stillbirth, and neonatal death.cats are the main reservoir for the toxoplasmosis which can contaminate the environments of other animal and human beings by their fa...
