Abstract
Climate change has brought issues of total crop failure in dry regions in Zimbabwe as evidenced by total crop failure in 2010, 2015 and 2017 in some parts of Chivi which is one of the driest area in Zimbabwe. The paper highlights the use of small grains for food security and climate compliant in dry regions of Zimbabwe. This brings in an idea of growing small grain by farmers as means of improving food production in dry areas such as Chivi, Mwenezi and Chiredzi districts. Cereal production growth in Sub-Saharan Africa is expected to decline by a net 3.2 percent in 2050 as a result of climate change. To mitigate this risk, there is need to improve productivity of small grains as climate compliant crops which can ameliorate poverty in Zimbabwe. Small grains are drought tolerant and perform better in dry regions than any other cereal crops. Sorghum and millet have the potential to contribute to food security to the world’s poorest agro-ecological regions.
Highlights
Phytobiotics, called phytogenic feed additives (PFA) are plant derived products added to feed in order to enhance the performance of livestock through the improvement of digestibility, nutrient absorption and elimination of pathogens residents in the animal gut [1, 2] Recent consumers' expectations in relation to food quality, have led to increasing use PFAs by poultry producers [3]
The results obtained from this experiment “The Effect of Garlic oil inclusion on carcass quality, growth performance and cost implication of Broiler Chickens is discussed below
Feed intake decreased as the level of garlic oil inclusion in the diets increased
Summary
Phytobiotics, called phytogenic feed additives (PFA) are plant derived products added to feed in order to enhance the performance of livestock through the improvement of digestibility, nutrient absorption and elimination of pathogens residents in the animal gut [1, 2] Recent consumers' expectations in relation to food quality, have led to increasing use PFAs by poultry producers [3]. The positive effects of these feed supplements on broiler performance, carcass characteristics and meat quality have been demonstrated [4]. The of use of natural promoters such as probiotics, prebiotics, symbiotics, enzymes, toxic binders, organic acids, oligosaccharides, phytogenics, and other feed additives, to enhance the growth and performance of broiler chickens have been advocated [9]. The objective of the present study was to evaluate the growth performance, carcass characteristics and cost implication of broiler chicken fed graded level of garlic oil inclusion
