Utilization of sun-dried maize offal with blood meal in diets for broiler chickens

Abstract

Sun-dried blend of maize offal and blood (SDMBM) was analyzed and its effect on the per- formance of broiler chickens (Anak-2000 strain) evaluated. Fresh blood prevented from coagu- lation, mixed with maize offal, was sun-dried, ground, mixed again with blood and ground into a meal after drying again. The crude protein, fat, fibre, ash, ADF and gross energy contents of SDMBM were, 362.0, 45.5, 31.8, 69.3, 52.3 g/kg DM and 4.245 kcal/g, respectively. It was ade- quate in all essential amino acids for growing broiler chickens except methionine. Eighty 14- day-old commercial broiler chicks were ran- domly allocated to four dietary treatments (fed ad libitum; four replicates each) consisting the control diet (0 g SDMBM/kg diet), which con- tained fishmeal, groundnut cake and soybean meal, and three other diets (50, 100 and 150 g SDMBM/kg diet). In a feeding trial, the starter (14 to 35 d) and finisher (35 to 49 d) dietary treat- ments did not have significant impact (P > 0.05) on body weight gain, efficiency of feed conver- sion, mortality and final body weights. The con- trol diet was inferior (P < 0.05) to 50, 100 and 150 g SDMBM/kg diets for feed cost per unit weight gain in the starter phase, 100 g SDMBM/kg diet in the finisher phase, and 100 and 150 g SDMBM/ kg diets for the whole period (14 to 49 d). Overall, the 100 and 150 g superior (P < 0.05) to the con- trol diet in cost of production per unit weight gain and all the SDMBM diets greater than con- trol in economic benefit per unit weight gain. Results suggest that dietary SDMBM up to 150 g/kg diet has a positive effect on broiler per- formance and can totally replace more expen- sive fishmeal

Chemical composition of solar dried blood and the ruminal content and its effect on performance of Japanese quails

“…The amount of lysine and methionine were 1.67 and 0.32 (g/100 g of feed) respectively in the feed, which were less than the values reported by Makinde [ 21 ] and amount of lysine content was more than the (1.30) and slightly less than the required methionine content of (0.50) for Japanese quail diet as per NRC [ 19 ]. This can be overcome by use of synthetic methionine reported by Makinde [ 23 ] and these results indicate the DBRC can be used as a better protein supplement for quails diet.…”

Solid State Fermentation of Maize (<i>Zea mays</i>) Offal by <i>Rhizopus</i> <i>oligosporus</i> under Acidic and Basic Conditions

“…Maize offal is a by-product of maize milling processes locally or industrially, which is conventionally utilized in livestock feeds formulation in Nigeria [1]. Maize offal contains about 150 g/kg crude protein and 85 g/kg crude fibre [2,3]. The comparatively low crude fibre content with relation to other by-products could be a reason for the utilization of maize offal as livestock feeds.…”

“…The comparatively low crude fibre content with relation to other by-products could be a reason for the utilization of maize offal as livestock feeds. However, the low protein composition appears to be a limitation to its usage by modern livestock feeds formulation industries in Nigeria [1][2][3][4][5]. This has resulted to some degree of environmental pollution orchestrated by inadequate utilization of maize offal by modern feeds formulation industries.…”

Physico-chemical composition of feed grade cassava peel meal fermented with different levels of baker's yeast

“…The method described by Makinde and Sonaiya (2007) was adopted with slight modification. To obtain BD of the experimental material, a pyrex glass funnel of known volume was weighed and test sample was poured into it and then leveled off.…”

“…The four most important physical characteristics that greatly influence the nutritional value,intake and performance of poultry diets are Water Holding capacity (WHC), Bulk Density (BD), Particle Size (PS) and Specific Gravity (SG). These attributes play important roles in controlling feeding (Makinde and Sonaiya, 2007;Okoli 2012). The BD of feed materials used in the Nigerian feed industries ranges from 0.02-0.41 g/cm while the WHC of energy and novel feedstuffs ranges from 0.35 -0.89 (g water/g feed) (Omede 2011).…”
