| dc.description.abstract | Broiler production has increased rapidly in tropical and subtropical regions in the past and
sustained growth is forecast for the future. One of the greatest challenges to efficient production
in these regions is reduced performance from warm and hot weather conditions. There are many
ways to decrease these detrimental effects of heat on broiler chickens. Aloe vera is one of the
oldest known medicinal plants but it is now realized that many of its active constituent may be
addressed in different ways by different formulations. Research since the 1986 review has largely
upheld the therapeutic claims made in the earlier papers having scientific proof that aloe vera
contains constituents such as antioxidants, enzyme, vitamins, mineral, mixtures those are
beneficial in alleviating some of the heat stress related to physiological responses and improving
thermo tolerance that accelerate growth performance, feed intake, FCR, water intake offal weight
of broiler in the stressful environment. It has a wonderful moisturizing agent and penetrates. It was
recently proven to stimulate the body’s immune system. There are many bioactive compounds
present in aloe but there is need of an appropriate and standard method to extract these active
components from plant material. Along with conventional methods, numerous new methods have
been established but till now no single method is regarded as standard for extracting bioactive
compounds from aloe. This study was conducted to determine the efficacy of aloe vera as a growth
promoter on the performance of broilers in stressful condition. The experimental day old chicks (250) were divided into 5 groups. Each group consisting of 50 chicks was designated as group To,
T1, T2, T3 and T4 The experiment was aimed at determining the influence of aloe vera gel on growth
performance of broilers such related with body weight gain, feed efficiency, feed intake, water
intake and offal weight(breast muscle, abdominal fat, dressing %). Providing 0 ml, 5ml, 10ml,
15ml and 20ml aloe vera gel was added in per liter drinking water. Similarly, it had no significant
(P>0.05) effect on liver, gizzard, thigh muscle and heart weight. But body weight gain and feed
efficiency were significantly (P<0.05) better than control group. In case of body weight gain and
feed efficiency 15% inclusion level of aloe vera gel is more appreciated and nutrient quality is
satisfactory where other inclusion level earned poor score. So we can recommend with 15% level. | en_US |
