Influence of processing temperature on chemical composition of solar-dried blood meal and on performance of broiler chickens

Abstract

An experiment was conducted to ascertain the optimum temperature for cooking (pre-heating) raw blood before solar drying. Raw blood was subjected to three cooking temperatures (50°, 70° and 90°C) for 30 min before solar drying at a temperature range from 45° to 56°C. In a feeding trial, four hundred and eighty 14-day-old broiler chickens were randomly allocated to four groups. The dietary treatments consisted of the control diet, which contained fish meal and soyabean meal as the main protein sources, and three isoenergetic and isoprotein diets each of which contained 75 g of one of the three types of solar dried blood meals (SDBM) kg 1 . Feed and water were provided ad libitum for a period of 6 weeks.There was no significant effect of the cooking temperature on the chemical composition of the solar-dried blood meals. The dietary treatments did not have significant (P>0.05) impact on feed intake, body weight gain, feed conversion efficiency or carcass yields. There were no health-related problems nor mortality attributable to the addition of SDBM to the diet.

Specialized protein products in broiler chicken nutrition: A review

“…Blood meal can be included in poultry and swine diets up to a level of 25% ( Hazarika, 1994 ). Previous reports have indicated that inclusion of 1–4% blood meal in diet can improve poultry performance ( Anang et al., 2001 , Nuarautelli et al., 1987 ), while others show no adverse effect of higher levels of dietary blood meal on chicken growth ( Donkoh et al., 2002 , Khawaja et al., 2007 ). However, Castelló et al.…”

Blood meal has been reported to be included in poultry feeds up to 25% level (Hazarika, 1994).…”

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

“…Drying of blood requires high cost equipment coupled with facilities for central blood collection, which may be unaffordable and/or not applicable because the abattoir structure in Nigeria exists as smallscattered units. Moreover, previous work with blood involving sun drying in the development of alternative feedstuffs for poultry reported a long drying time of about three days (Adeniji 1995;Donkoh et al 2002;Odunsi et al 2004). However, previous studies by Sonaiya (1988) suggested the use of crop by-product materials as absorbents for blood in order to increase the surface area for quicker sun drying.…”
