Analyzing raw materials to determine the actual nutritional composition before formulating feed is the best way to minimize nutrient variation in feed and also to manage cost.
In Nigeria, analysis of raw materials is gaining much importance in feed manufacturing with a good number of the major feed millers acquiring NIR machines for both raw material and feed analysis and also extending the services to small –medium scale operators who cannot afford their own machines.
However, despite the huge investments in establishing NIR laboratories for quick profiling of raw materials, there is a challenge of analyzing the amino acid composition of the raw materials. So far, there is no record of any laboratory capable of analyzing amino acid in raw materials within the West African sub region. Today, the world of Animal Nutrition (especially for poultry, swine and aquaculture) has progressed far beyond formulating feed on crude protein to that of essential amino acids. Formulating feed on amino acid requirements has proven to be cost effective, environmentally friendly and ensuring quality feed for poultry, swine and aquaculture.
In light of this, I am pleased to present to you the maiden edition of the Nigerian Raw Material Report 2015. This report is based on raw material samples received from notable Feed mills in Nigeria within the period of June, 2014 to September, 2015. With the exception of corn bran and cassava siftings which were analyzed using wet chemistry at our main laboratory in Hanau, Germany, all other raw materials were analyzed at our Satellite NIR Laboratory in Midrand, South Africa, using the Evonik AMINONIR® and AMINOProx® services. The Nigerian Raw Material Report 2015 includes total amino acid content, standardized ileal digestible amino acid content (SID Poultry), proximate nutrients, total and phytic phosphorous as well as energy predictions. For each nutrient, calculations for the mean values, minimum and maximum, standard deviation and coefficient of variation have been done. Energy estimation was done using various prediction equations which have been included in the report for reference. I trust that you will find value in the raw material information described in this maiden report for Nigeria.

Two experiments were carried out to determine the effect of Sorghum-Barley Brewer’s Spent Grain (... more Two experiments were carried out to determine the effect of Sorghum-Barley Brewer’s Spent Grain (SBBSG) based diets on the performance of chicken. The studies were carried out to discover alternative feed ingredients to reduce the cost of feed in the Ghanaian poultry industry. Experiment I was conducted to determine if the inclusion of Sorghum-Barley Brewer’s Spent Grain (SBBSG) in laying hen diets will affect egg laying performance and egg quality. A total of 300 Bovan Brown laying hens (37 weeks old) were randomly allocated to five dietary treatments, T1, T2, T3, T4 and T5 in a completely randomized design, in a trial that lasted 112 days. The treatments represented 0, 5, 10, 15 and 20% SBBSG inclusion respectively and each treatment was replicated four times with 15 birds per replicate. Feed and water were provided ad-lib. Eggs laid were collected twice daily and laying performance and egg quality characteristics determined. Hen-day egg production was similar (P>0.05) among the treatment diets (86.67, 89.72, 86.59, 84.21% and 87.93%). Feed Conversion Efficiency was significantly higher (P<0.05) for 15% and 20% (0.54 and 0.54 respectively) compared to 0%, 5%, and 10% (0.53, 0.53 and 0.53 respectively). Shell thickness was significantly thicker (P<0.05) for the 20% (0.44mm) compared to 0%, 5%, 10%, and 15% (0.42, 0.42, 0.43, and 0.42mm) respectively. Feed intake was similar among the treatments, as was egg weight. Generally, Haugh Unit and albumen height improved with SBBSG inclusion rate. Birds on the control diet had egg yolks with the highest cholesterol concentration (414.9 mg/dl) and this was significantly higher (P<0.05) than cholesterol concentration of yolks from 5%, 10%, 15% and 20% (266.66, 279.62, 243.52 and 246.61mg/dl) respectively. The present study shows that SBBSG can effectively be included in laying hen diets up to 20% without any adverse effect on laying performance and egg quality.
Experiment II was carried out to determine if the inclusion of Sorghum-Barley Brewer’s Spent Grain (SBBSG) in broiler diets will affect growth performance and carcass characteristics. A total of 380 Ross broiler chicks were brooded on a common diet without SBBSG for 28 days after which they were randomly assigned to five experimental diets, T1, T2, T3, T4 and T5 representing 0, 4, 8, 12 and 16% SBBSG inclusion respectively in a completely randomized design. There were four replicates per treatment and each replicate had 19 birds. The test period was 28 days and consisted of a grower phase (14 days) and a finisher phase (14 days). Water and feed were provided ad libitum. Production parameters measured included average daily gain, feed intake and feed conversion efficiency. At the end of the trial, 3 birds from each replicate were slaughtered and used for carcass analysis. Parameters measured included dressing percentage, intestinal weight, liver and gizzard weights and abdominal fat. There were no significant differences (P>0.05) among all the diets for any of the production parameters measured. Similarly, except for abdominal fat where birds on 12% and 16% had significantly higher and different (P<0.05) values (29.40 and 37.99g) compared to 0%, 4%, and 8%, (18.47, 17.41, and 21.07g respectively), all the other carcass parameters measured were not significantly different (P>0.05). The present study shows that SBBSG can be included in broiler diets up to 16% without adverse effects on the performance characteristics accessed, and up to 8% without a significant increase in abdominal fat. For better utilization of brewer’s spent grains especially in the poultry sector, brewery industries in the country should incorporate drying of their wet spent grains into their chain of production. Alternatively, farmers may also take advantage of the abundant sunshine for the drying the SBBSG for efficient utilization.
