We investigated the composition of fatty acids in adipose tissue, serum, and liver of cows that were fed at restricted energy intake or were overfed during the dry period. Overfed cows had higher concentrations of serum nonesterified fatty acids and consequently accumulated greater amounts of triacylglycerols in the liver than did cows that were fed at(More)
During the dry period, cows were either fed restricted amounts or were overfed to study lipolytic rates in adipose tissue. Higher lipolytic rates can result in greater accumulation of triacylglycerols in liver and, subsequently, hepatic lipidosis. Adipose tissue was biopsied at -1, 0.5, 1, 2, and 3 wk from parturition. The basal in vitro lipolytic rate was(More)
The prevalence of antibodies against Toxoplasma gondii was investigated by commercial latex agglutination test kit (Toxocheck-MT 'Eiken') in captive felids maintained at zoos and a wildlife breeding center in different geographic regions of Thailand. Sera from a total of 136 captive felids of 12 species was obtained between 2002 and 2004. The overall(More)
In dairy cows, overfeeding during the dry period leads to overcondition at calving and to depression of appetite after calving. As a consequence, at calving overconditioned high-producing dairy cows inevitably go into a more severe negative energy balance (NEB) postpartum than cows that have a normal appetite. During the period of NEB, the energy(More)
Negative energy balance was studied in 45 periparturient dairy cows from 15 small-holder farms in Kamphaengsaen District, Nakhon Pathom Province. Blood samples were collected at 1 week prepartum and 2 and 4 weeks postpartum for evaluation of negative energy balance and to study the relationship between concentrations of serum non-esterified fatty acid,(More)
The present study compared the hepatic fatty acid composition of cows that were fed a high energy diet during the dry period to induce fatty liver after parturition with that of control cows. Treated cows had higher concentrations of plasma nonesterified fatty acids as a result of greater lipolysis after parturition than did control cows; consequently, the(More)
The purpose of this study was to compare the hepatic enzyme activities of gluconeogenesis between control cows and experimental cows that had been overfed during the dry period to induce fatty liver postpartum. Blood and liver samples were collected 1 wk before and 0.5, 1, 2, and 3 wk after parturition. Before parturition, neither the serum nonesterified(More)
In tropical countries such as Thailand, dairy cows particularly raised in small-holder farms are confronted by a problem of improper nutritional management and its consequences, which may lead to impair their production, health and fertility. This review attempted to summarize some nutritional factors influencing reproductive performance especially during(More)
The aim of this study is to explain the social networks of the backyard chicken in Ratchaburi, Suphan Buri and Nakhon Pathom Provinces. In this study, we designed the nodes as groups of persons or places involved in activities relating to backyard chickens. The ties are all activities related to the nodes. The study applied a partial network approach to(More)
The relationship between accumulation of triacylglycerols in the liver and first ovulation post partum was studied in an experiment with 32 dairy cows. During the dry period, 16 treated cows were fed a high energy diet to induce overconditioning, while 16 control cows were fed a recommended diet. After parturition, the treated cows entered deeper negative(More)
