This paper reports an investigation into metabolic and endocrine maturity in the neonate lamb and the relationships between litter size, birth weight, and maternal metabolic and endocrine variables on behavior at birth and survival over the first 72 h of life. Data were from multiparous, fine-wool Merino ewes (n = 150; equal numbers of single-lamb and twin-lamb bearing status) lambed on pasture...

The objective of the present study was to test the hypothesis that parturition duration is related to birth asphyxia in lambs and that asphyxia affects newborn lamb viability and vigor. Two sire and dam genotypes (Texel: TX; Polwarth: PW) and their crosses were represented in the study. Eighty lambs (25 PW sire × PW dam, 13 TX × TX, 25 TX × PW, and 17 PW × TX) born to 69 grazing ewes were used....

castration of male animal's leads to a reduction in aggressive behavior, which animals will avoid wasting energy resulting to economic production of the animal, grows. it also reduces damage and bruising animals and increases normed meat producing at slaughter. in this study, 20 lambs ghezel breed in four age groups, group 1: one month (n = 4), group 2: two months (n = 4) group 3: three months ...

The evolution of conspicuous sexually selected traits, such as horns or antlers, has fascinated biologists for more than a century. Elaborate traits can only evolve if they substantially increase reproduction, because they probably incur survival costs to the bearer. Total selection on these traits, however, includes sexual selection on sires and viability selection on offspring and can be infl...

Forty ewes (3-6 years of age, average weight 41.2 kg)were randomly chosen from the flock of the sheep experiment station of Tripoli University. Ewes were divided into two groups, control group (C) received untreated barley straw and treatment group (T) received barley straw treated with 10% urea solution applied as 40% (V/W). Barley straw was sprayed with molasses when fed to animals. Both grou...

We carefully analyze the WFPC2 and STIS images of GRB970228. We measure magnitudes for the GRB970228 point source component in the WFPC2 images of V = 26.20 −0.13, Ic = 23.94 +0.10 −0.09 and V = 26.52 +0.16 −0.18, Ic = 24.31 +0.15 −0.11 on March 26 and April 7, respectively; and Rc = 27.09 +0.14 −0.14 on September 4 in the STIS image. For the extended component, we measure magnitudes of Rc = 25...

skeletal abnormalities are most often used to describe defects in the arms or legs that are associated with genes or chromosomes, or that occur due to an event that happens during pregnancy. spider lamb syndrome (sls) is a congenital disorder in sheep breeding that is recognized by some deformities in skeletal system especially in the limbs.a dead day-old cross-breed white lamb with deformed li...

2015 © American Water Works Association JOURNAL AWWA OCTOBER 2015 | 107:10 Tularemia is an acute febrile zoonotic disease caused by the bacterium Francisella tularensis. Shortly after the initial isolation of the organism in Tulare County, Calif. (McCoy & Chapin 1912), the first case of a human infection was reported from Cincinnati, Ohio (Wherry & Lamb 1914). The first documented waterborne ou...
