this study investigated the effects of five levels of galanin on plasma concentrations of growth hormone , triiodothyronine, thyroxine and milk fat in dairy goat breed was sannan .15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments ( three replicates per treatment ). levels of the hormone injection of gala...

Fecal culture has been the primary method used to diagnose paratuberculosis in goats. It is laborious, slow, and expensive. Validation of enzyme-linked immunosorbent assays (ELISAs) on milk samples could make paratuberculosis testing more widely available for goat farmers. The aim of this study was to determine the accuracy of serum and milk ELISAs for paratuberculosis, relative to fecal cultur...

OBJECTIVE This experiment investigated the effects of aflatoxin B1 (AFB1) alone or mixed with ochratoxin A (OTA) and/or zearalenone (ZEA) on the metabolism, immune function, and antioxidant status of dairy goats. METHODS Fifty lactating Laoshan dairy goats were randomly assigned to one of five treatment groups (n = 10) for 14 days. Goats were fed no additive (control) or administered with 50 ...

The focus of this work is to determine the distribution and identify species of Eimeria parasites of dairy goats in the livestock of the National Goat and Sheep Research Center in Sobral, State of Ceará, Northeast Brazil. Results showed the presence of multiple species in 196 of 215 analyzed samples (91.2%). Fifty five out of these were from kids (28%) and 141 from adult goats (72%). Eight diff...

The objective of this study was to investigate the effect of hCG administration 5 days after breeding on plasma progesterone (P4) concentration and reproductive performance of oestrous-induced nulliparous dairy goats. A total of 59 nulliparous goats (36 Alpine and 23 Saanen) received intravaginal sponges with 60 mg medroxyprogesterone acetate for 9 days plus 200 IU equine chorionic gonadotrophi...

When loose-housed dairy goats feed in close proximity to each other, frequent social conflicts are often reported. The aim of this study was to investigate whether the cardiac activity of dairy goats is affected when they are obliged to feed side-by-side in close proximity. In five dyads of goats each stemming from eight groups (8x5 dyads) differing in terms of grouping age and presence of horn...

The objective of this study was to determine seroprevalence of small ruminant lentivirus (SRLV), Brucella abortus and Brucella melitensis infections among dairy goats in South Backa and Srem region in Vojvodina Province. The other aim was to determine the risk factors associated with SRLV infection in investigated herds. A total of 971 serum samples were collected from 8 comercial dairy goat he...

This investigation reported for the first time the occurrence of intramammary infections caused by Staphylococcus in primiparous replacement goats before parturition and the persistence of clinical Staphylococcus aureus infection during the lactation period. Subclinical infections, mainly caused by coagulase negative staphylococci (CoNS), did not persist during lactation. Genotyping analysis in...
