Study of some minerals deficiency in grazing sheep in Thi-Qar Province

Abstract

This study was carried out on 250 locally sheep collected from four sides of Thi-Qar Governorate. The clinical, hematological, trace elements changes in naturally occurring minerals deficiency in sheep were described. Anemia & Pale mucous membranes, Alopecia &steely wool, Diarrhea, parakeratosis, pica and abortion constituted the main signs and symptoms. The respiratory and heart rates were significantly higher (p<0.05) in mineral deficient sheep than in normal control sheep in one side of province. Values of total erythrocyte count, hemoglobin concentration and packed cell volume were significantly lower (p<0.05) in mineral deficient sheep than in normal control sheep. Significant differences were not found in total leukocyte count and differential leukocyte count values in sick and normal control sheep. Copper, Zinc and Iron values in the serum were significantly lower (p<0.05) in mineral deficient than in normal control sheep. The erythrocytes morphology appeared a abnormal shapes and size, this refer to Macrocytic hypochromic anemia and Normocytic hypochromic anemia, It was concluded that a significant changes were noticed between diseased and control sheep in clinical hematological values and trace elements and abnormal erythrocytes morphology, deficiency of a single element seldom occurs under field condition in Thi-Qar Governorate.

The relationship between deficiency of some trace elements, oxidative stress, immunoglobulin E and vitamin A in sheep affected with skin diseases

“…This also came along with Spears et al (2008), who recorded that the early sign of dark wool depigmentation may also be seen in case of copper deficiency. It was recorded in our study that copper deficiency associated with alopecia as well as decreased wool production and this agreed with Niekerk et al (1989) The result agreed with White (2004), Ali et al (2012) and Mohammed et al (2013), who reported that loss of wool appearance of alopecia in sheep with copper deficiency.…”

Estimation of Serum Copper Concentrations in Sheep and Goats Infected with Gastrointestinal Parasites in Mosul City, Iraq

“…Biochemically, roundworm infection in sheep and goats decreases copper absorption resulting in decline of copper concentration in serum (3) Copper plays an important role in regulating the mechanisms of different enzymes, particularly metabolic enzymes (4). Copper deficiency may cause dysfunction in reproductive, digestive, nervous, immune performance, and cardiovascular systems (5,6). Therefore, copper deficiency results in several clinical signs including anemia, diarrhea, poor wool production, and trembling (7).…”
