Correlation between milk consumption and body weight of white Fulani calves under semi-intensive management and linear body measurements
Srave, D. T.

Abstract: A study was conducted to determine the correlation between milk intake and body weight with linear body measurements in white Fulani calves raised in semi-intensive system of management. The overall mean±SEM value for milk intake, body weight, neck circumference, neck length, body length, body circumference, girth circumference, height at wither and tail length were 1.20±0.40g, 5.18±1.02kg, 21.54±0.66cm, 13.23±0.21cm, 28.36±0.31cm, 36.41±0.43cm, 35.84±0.37cm, 35.87±0.43cm and 23.43±0.39cm respectively. There was significant (P<0.05) effect of lactation stage on all body measurements taken except for neck circumference and tail length. Correlation between all body pairs of measurements were high, positive and highly significant (P<0.01, P<0.05). The highest correlation was recorded for body length, body circumference, girth circumference and height at wither. Linear function provided the best fit for milk intake weight and linear body measurements indicating that body measurements can be used for selection and the estimation of body weight in the fields were accurate scales are not usually available. It is recommended that any of the body measurement parameters could be used in the estimation of the body weight. Also, an improvement of non-genetic factor such as nutrition and general husbandry of the animal will bring about improvement in the body parameters as well as maintaining the animal’s physiological balance.

Abstract: Leafy vegetables are the major dietary source of vitamins, minerals, fibers and bioactive compounds. Due to rapid urbanization and industrialization, an increasing level of heavy metals in vegetables has been noticed in recent years. This study aimed to evaluate the effects of cow manure and ash like materials for reducing arsenic and lead accumulation in three common leafy vegetables. Therefore, a cross-sectional study was conducted on three leafy vegetable samples in Chattogram, Bangladesh. A total of 54 leafy vegetable samples of three species like water spinach, spinach and red amaranth were collected from the six treatment groups which were treated with wood ash, cow manure, charcoal and their mixture and the concentration of arsenic and lead were evaluated by Atomic Absorption Spectrometry (AAS). Results indicated that soil contains a higher level of lead which exceeds the maximum permissible limit followed by WHO. Again, cow manure, wood ash and charcoal significantly reduce the concentration of arsenic and lead in soil. Accumulation of arsenic was significantly reduced by the mixture of cow manure and charcoal in Water Spinach, wood ash and mixture of wood ash and charcoal in Spinach, and wood ash in Red Amaranth. Again, the accumulation of lead was reduced by cow manure, wood ash, charcoal and their mixture, though this reduction was not significant. So, cow manure, wood ash and charcoal have a significant effect on the arsenic accumulation in leafy vegetables because they increase the stability and decrease the mobility of heavy metals in soil.
