This study aimed to determine milk production and efficiency of feed utilization a mixed mineral-enriched essential oils supplementation lactating dairy cows. Forty-eight Holstein-Friesian cows with 3.45±0.58 body condition score 187.08±21.53 days in were randomly allocated two dietary treatments for 46 days. Treatments consisted no (CON) or (AGB) 0.5% Agromix Booster® the Total Mix Ration (TMR...

Kellner (1920)) in his calorimetric studies with cattle, showed that, as the fibre content of the ration increased, the net availability of its metabolizable energy fell. He attributed this fall to the additional physical work with consequent loss of heat in comminuting and digesting the more fibrous food. This cause may not be the sole contributor. Data in the literature, as summarized in Tabl...

abstract pollution is a world problem with serious consequences. heavy metals are an important group of these contaminants and enter aquatic ecosystems from anthropogenic and natural sources and animal health and systems are affected. in this study, the effect of lead exposure (3 mg/l concentration, 30 days) on activity of tissue enzymes, including acetyl cholinesterase, alanine aminotransferas...

objective: this study was conducted to evaluate the effects of different proportions of marshmallow extract (althaea officinalis l.) on growth performance and carcass composition of common carp (cyprinus carpio). methods: common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (a. officinalis) extract 0.25%, 0.50 and 1%, and with no...

objective: in this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) chironomid larvae were examined. methods: for this purpose, 2.5 grams of food per coconut considered in the period, with three replicates and chironomid larvae during the period of 15 days in plastic pans were kept in nut...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...
