Blood and milk responses to nutritional and climatic factors in Desert goats

The effects of nutritional and climatic factors on temperature regulation, dry matter intake (DMI), water consumption, blood composition and milk yield and composition were investigated in desert goats. Increasing dietary crude protein (CP) level from 14.2 to 18.7% increased rectal temperature (Tr) and respiration rate (RR), DMI and water consumption and milk yield in all stages of lactation....

Studies on Altered Thyroid Function in Nubian Goats

The effects of triiodothyronine (T3)-induced hyperthyroidism, and of carbimazole-produced hypothroidisin on lipid metabolism, histology of vital organs and serum constituents in Nubian goats were studied. Groups of goats were given T3 and carbimazole by oral route daily for 14 days at doses of 250, 400 and 550 µg/goat and 60 and 90 mg/goat, respectively. T3 treatment decreased serum, liver...

Studies on Lipid Metabolism in the Camel (Camelus Dromedarius)

1. Lipids were extracted from the following tissues of single humped camels (Camelus dromedarius): hump, mesentery, perinephric, liver, kidney, heart, muscle, digesta and plasma. The normal lipid levels expressed as milligrams of total lipids per gram wet tissue were found to be as follows:- Hump 238, mesentery 273, perinephric 256, liver 27.3, heart 24.3 and kidney 23.3. Normal plasma lipid...

Iodine Metabolism in Domestic Animals

Iodine metabolism was studied in camels, goats and sheep using radio-active iodine I131. The percentage averages of I131 uptake in camels at 3-hour, 24-hour and 48-hour intervals were found to be 1.72%, 5.56% and 10.14%, respectively. The uptake in goats was much higher than in camels giving 5.31%, 18.5%, 23.1% and 36.7% for the same intervals and maximum uptake. The average uptake in sheep was...

Comparative Assay of the Thyroid Hormones in Cattle, Sheep, Goats and Camels in the Sudan

The weights of the fresh thyroid glands of the four animal species considered in this study were found to be in close agreement with the findings obtained by A/Wahab et al. (1967) and Afiefy (1966) for the same animals in Egyptian breeds. The water and fat contents in the thyroid glands of these animals as judged by the drying factor are similar with only very minor differences. The total...

Physiological Responses Of The Domestic Rabbit (Oryctolagus Cuniculus) To Diabetes Mellitus As Affected By Dietary Starch And Lipid Supplementation And Thermal Environment

The objective of this work was to study the effects of dietary factors, medicinal plant and thermal environment on diabetic rabbits. In experiment 1, six trials were conducted to determine effective dose of alloxan for induction of chronic diabetes in rabbits. When rabbits were injected with three doses of alloxan: 100 mg/kg ,50 mg/kg, 75 mg/kg, and 65mg/kg combined with glucose and...

Factors Affecting Forestomach Motility and Food Intake in Goats

Well trained goats with rumen cannulae were used to investigate effects of feeding levels on forestomach motility incrimination using ad libitum and deprived feeding regime. They were also used to investigate the effect of intravenous infusion of individual and of volatile fatty acids, intravenous infusion of glucose and injection of ^5;2adrenergic drugs on forestomach motility, rumination and...

Responses of Broiler Chicks to Feed Restriction and Energy Levels Under Tropical Conditions

Summer and winter trials were conducted to investigate responses of broiler chicks (Hypeco) to early and late restriction under varying energy levels during these seasons. The feed restriction of fasting -a- day during the week for 3 weeks applied either early or at the end late of the whole period (49 days). Three levels of energy were fed: (2800, 3000 & 3200 Kcal/kg) which were low, medium...

Seasonal Variations in the Haemogram of Desert Sheep

Effects of seasonal changes in thermal environment and age (1.0-3.0 years) of animals on haematological values of 20 Desert ewes in Shambat area were investigated during wet summer, winter and dry summer, successively. There were marked seasonal changes in ambient temperature and relative humidity and the animals experienced the highest heat load during dry summer, then wet summer and the...

Seasonal Fluctuations in the Haematological Values of the Nubian Goats

This study was to investigate effects of seasonal changes in thermal environment and relative humidity as well as the effect of age on certain haematological values in Nubian goats under tropical conditions of northern Sudan in Shambat (16°N) during July 1995.-June 1996. The climatic data showed that the highest values for maximum temperature were reported in dry summer followed by wet summer...
