Specific Gravity of Live Sheep

Determination of the Specific Gravity of Live Sheep

It has been shown by Behnke (1941) , Pace and Rathbun (1945) and others that there is a good relationship between percentage total body fat and specific gravity (S.G.) in a number of different species of animal. Methods of measuring the volumes of live animals to determine S.G., have usually involved immersion in water, but there are difficulties in this procedure due to air retained in the bod...

Development of an Attenuated Live Virus Vaccine against Sheep Pox

Dual X-ray absorptiometry accurately predicts carcass composition from live sheep and chemical composition of live and dead sheep.

Fifty merino wethers (liveweight range from 44 to 81kg, average of 58.6kg) were lot fed for 42d and scanned through a dual X-ray absorptiometry (DXA) as both a live animal and whole carcass (carcass weight range from 15 to 32kg, average of 22.9kg) producing measures of total tissue, lean, fat and bone content. The carcasses were subsequently boned out into saleable cuts and the weights and yiel...

Ruminal Kinetics of Nutrients Degradation, Hydration, and Functional Specific Gravity of Three Types of Beet Pulp

Two experiments were conducted to evaluate the relationships between nutrients degradability, kinetics of hydration, functional specific gravity (FSG) of the three types of beet pulp (BP) including fine (FBP), normal (NBP) and pelleted (PBP) BP. In experiment 1, about 3 g of samples was weighed in sealed nylon bags (6 cm×7.5 cm, 40±5 µm pore size), incubated in rumen of two cannulated Holstein ...

Application of Body Measurements of Blackhead Somali Sheep as Parameters for Estimation of Live Weight

Sheep and goat have a great role in the economy of the pastoral communities which have inhabited in the lowland parts Ethiopia. The study was conducted in Borana low land southern Ethiopia to predict the body weight of blackhead Somali (BHS) sheep using linear body measurements under farm condition. A total of 478 heads (301 female and 177 males) were measured for linear body measurements and b...
