Heat Tolerance Attributes of Locally Adapted Chicken in the Derived Savannah Zone of Nigeria

This study was carried out to determine the effect of genotype on the rectal temperature, respiratory rate, and pulse rate of locally adapted chickens in the derived savanna zone of Nigeria. A total of two hundred and eighty-eight (288) chickens were used for this study. These consisted of 96 birds each of normal feather, frizzle feather and Fulani ecotype chicken genotypes.

RENAL TISSUE AND SERUM IMMUNOGLOBULIN G OF HYPERTHYROID RATS

ABSTRACT There are several interactions between thyroid and kidney functions in health and disease states. Thyroid hormones affect renal development and physiology. Thyroid hormones have pre-renal and intrinsic renal effects by which they increase the renal blood flow and the glomerular filtration rate (GFR). Hyperthyroidism results in increase GFR as well as increased renin-angiotensin-aldosterone activation. This study was carried out to investigate changes in renal tissue and...

CHANGES IN SOME HEMATOLOGICAL PARAMETERS IN DIABETIC RATS TREATED WITH LEAF EXTRACT OF TERMINALIA CATAPPA (INDIAN ALMOND) AND NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)

AbstractThe changes in some haematological parameters in alloxan-induced diabetic rats treated with Terminalia catappa leaves extract and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) was studied. 54 male albino wister rats were selected into nine (9) groups of six (6) rats each. Diabetes was induced intraperitoneally to the test groups with 150mg/kg BW of alloxan monohydrate and the experiment lasted for 14 days. Group 1 was control which received 1mg/kg of deionized water, group 2 was extr...

EFFECTS OF STAGE OF LACTATION AND PARITY ON BLOOD VOLUME AND MILK YIELD IN WEST AFRICAN DWARF SHEEP

ABSTRACTA study on the effects of stage of lactation and parity on blood volume and milk yield in West African Dwarf sheep was carried out using (12) lactating West African Dwarf sheep for twelve (12) weeks of lactation. In the second week of the experiment, the dams were weighed using pocket balance scale. Evans blue dye solution was injected into the animal through the jugular vein and waited for 10-15 minutes before bleeding the animal through the same media. The milk yield were measured i...
