BACKGROUND: Mineral elements for various activities such as biochemical, productive and reproductive functions of animals are necessary and their concentration in the body of animals, under the influence of soil and plants will be different in each region. OBJECTIVES: The aim of present experiment was determination of concentration of macro and micro minerals in blood of gazing camel in the pastures of Khuzestan. METHODS: Eighty-eight camels under 11 classes, according to age and physiological situation in Hoveyzeh, Jofeir and Abadan-Khoramshahr regions were investigated during the autumn and winter grazing seasons. RESULTS: Concentrations of calcium, magnesium, sodium, potassium, chloride and iron in serum of all class of camels were in the optimal range, compared to the critical level. The concentrations of camels blood Zn and Cu were under critical level, so they were deficient, the P was near the deficiency threshold. Concentration of Mn was low. CONCLUSIONS: Therefore, as important roles of minerals in improvement of production and reproductive situations of camels in these regions, the mineral status of feedlot must be improved by proper mineral supplementation, the results of present experiment could be useful.

The present study was conducted in Basra province to evaluate of some minerals (copper,, zinc and cobalt) in sheep. The study constituent examination of 1400 sheep and 200 of it showed sings of mineral deficiency and 25 as a control, the study include: clinical, hematological examination, and level of serum(copper, zinc, and cobalt). A number of 200 (14.2%) sheep revealed a clinical signs of mineral deficiency from total of (1400) sheep which were clinically examined in this study, And the study showed that the values of copper, zinc, and cobalt in serum were significantly low (0.15±0.03ppm, 0.73±0.35ppm, 0.57±0.12ppm). and the most important clinical signs presented by alopecia (47.5 %), parakiratosis (18%), diarrhea (11.5%), pale mucous membrane (49%), lacrimation (6%), ataxia (4%). Also the study reveal that the body temperature within normal (39.47±0.33 C°), but increase of pulse rate, and respiratory rate in affected animals were (90.48± 4.53Min, 33.99±0.29 Min) respectively. And the study showed that the RBCc of affected sheep significantly low (6.57±0.10 *106/ml), also the PCV, Hb, MCV, MCH, were significantly low (19.75±0.24 %, 6.88±0.11 g/L, 31.07±0.49 fl, 11.06±0.53 pg) respectively, whereas MCHC in affected sheep was significantly high (34.92±0.45 %) and the mean of WBCc of affected sheep were(6.43±0.11103/ml) and there is no significant different when compared with control.

The dynamics of some serum mineral concentrations during the first weeks of life of native and crossbred newborn calves in Assiut governorate were investigated. Blood samples of 25 Balady and 25 crossbred (Friesian x native) male calves were investigated. Blood was drawn from calves at 1, 7, 14 and 21 days after parturition. Serum levels of calcium (Ca), phosphorous (P), magnesium (Mg), sodium (Na), chloride (Cl), potassium (K), iron (Fe), Copper (Cu) and zinc (Zn) were monitored. Levels of Ca, P, Fe, Cu and Zn increased (P < 0.05) in relation to age of Balady and crossbred calves when compared by the day 1 of age. In contrast, decreased in concentrations of Na and Cl (P < 0.05) in relation to age of Balady and crossbred calves when compared by the day 1 of age were detected whereas Mg and K values remained unchanged. Native calves had higher (P < 0.05) Ca, P and Fe in the 7th day than crossbred calves whereas Na and Cl were higher (P < 0.05) in native calves than crossbred calves at the first day after birth. Results from this study suggested that breed and age may play an important role in mineral homeostasis during the first weeks of life in the newly borne bovine calves.

Objective: This study aimed to use the potential chitosan processing waste from shrimp heads as a premix to improve the production performance of laying chickens. Materials and Methods: This research uses shrimp head waste, NaOH, hydrochloric acid, Na₂SeO₃, and NaCl solutions. Processing shrimp head waste into chitosan is done in three ways, namely demineralization, deproteination, and deacetylation. Each of the resulting liquid wastes is then mixed until a neutral mixture is obtained. The data observed were the nutrient and amino acid content of liquid waste from the deproteinization, demineralization, and deacetylation processes, as well as the neutral mixture. Results: The results showed liquid waste from the process of making chitosan from shrimp head waste using deproteination, demineralization, and deacetylation methods, as well as a neutral mixture containing little energy, protein, and fat but is rich in minerals. The most abundant and complete amino acid content is found in deproteination process wastewater and neutral mixtures. Conclusion: In conclusion, the waste from making chitosan from shrimp head waste through deproteinization, demineralization, and deacetylation, and the neutral mixture contains enough minerals and amino acids needed by livestock, so it has the potential to be used as a premix.

O terceiro osso metacarpiano equino é uma região de particular interesse devido ao grande número de lesões a que está sujeito. Assim, justifica-se o estudo detalhado da sua estrutura anatômica, dimensões e composição elementar para o aprimoramento de técnicas de diagnóstico, tratamento e prevenção de lesões. Neste trabalho,foi estudada a composição macroelementar óssea de 30 pares de osso terceiro metacarpiano equino e sua relação com a idade, sexo, peso, raça, alimentação e atividade dos animais. As concentrações médias de cálcio e fósforo das amostras foram 205 ± 62 mg/g e 97 ± 32 mg/g, respectivamente. A relação [Ca]/[P] encontrada foi de 2,12 ± 0,13, indicando que a proporção entre o cálcio e fósforo no tecido ósseo é constante e aproximadamente igual à razão 2:1. A análise estatística dos dados mostrou normalidade para todo o conjunto de medidas. A avaliação entre os animais com atividade física intensa e os animais com atividade física leve, em que a quantidade de material mineralizado para o primeiro e segundo conjuntos são, respectivamente, [Ca] = 222 ± 57 mg/g e [Ca] = 179 ± 47 mg/g, evidenciou a existência de correlação estatística entre o depósito de material mineral e a função exercida pelos animais. Para as demais características, não foram verificadas evidências estatísticas de inter-relações. Tais achados serão subsídios para estudos posteriores acerca de possíveis correlações com enfermidades de origem fisiológica ou nutricional frente à casuística de fraturas e outras afecções comuns ao aparelho locomotor equino.
