This study was to investigate the effects of Qingwen Baidu granules on the antibody level, immune organ index and the lymphocyte transformation of broilers. Hy-line variety white cocks of 30 days were used to evaluate the antibody titer of Newcastle Disease in each serum group, and MTT method was used to determine the T lymphocyte proliferation, and organ weighing methods to measure the immune ...

Shortly after we had demonstrated in this laboratory (1) that nutritional anemia could be induced in rabbits by a diet of cow’s whole milk, and that this anemia could not be corrected by inorganic iron unless it was supplemented with a natural food material, or a preparation from this material, we attempted to use chicks as experimental animals for anemia studies. A survey of the literature at ...

Some experiments have recently been described (Fenn, 1927) which successfully demonstrated an increased oxygen consumption of the nerves of dogfish and frogs during stimulation, thus confirming Tashiro (1913) and Parker (1924-25) who measured CO2 output as well as Downing, Gerard, and Hill (1926) and Gerard (1927, a and b) who measured heat production. The apparatus, a differential volumeter, c...

BACKGROUND Avian leukosis virus (ALV) is one of the main causes of tumour development within the poultry industry in China. The subgroup J avian leukosis viruses (ALV-J), which induce erythroblastosis and myelocytomatosis, have the greatest pathogenicity and transmission ability within this class of viruses. ALV can be transmitted both horizontally and vertically; however, the effects of ALV in...

This study aimed to examine the effect of bird age on the contents of endogenous bioactive compounds, including carnosine, anserine, creatine, betaine, and carnitine, in meat from a certified meat-type commercial Korean native chicken strain (KNC; Woorimatdag). Additionally, the effects of the meat type (breast or leg meat) and the state of the meat (raw or cooked) were examined. Cocks of KNC w...

Adult guardianship is not a new idea; the concept was recognized in Roman times (McLaughlin, 1979; Sherman, 1980). Common law adult guardianship originated in the 13th century prerogative powers of the royal courts of England, who could appoint a person known as a “committee” of the person or his property (Krasik, 1989; Neugebauer, 1978). Over much of their life, these powers were administered ...

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old ...
