Nigella seed Oil meal as a protein supplement in broiler diets
|
|
Abstract: Feed cost is the most important of itemized costs, it is known that protein is an expensive component of poultry diets and that supply of protein may not be adequate to support the expansion of poultry production.
Nigella oil is being produce on commercial scale and used for many medicinal purposes. However, the press cake or by-product which is rich in protein is not efficiently utilized.
This work was conducted in Poultry Production Department, Faculty of Agriculture, University of Alexandria to investigate and evaluate the possibility of using Nigella seed oil meal (NSOM) as a source of protein or as a feed additive.
Proximate analysis, mineral and amino acids content:
1- The results indicate that NSOM has 32.00% protein, and considerable amount of fat 17.50%, NFE 24.60% and ash 6.00%..
2- It has high percentage of iron and magnesium and considerable amounts of zinc, manganese, calcium, sodium and potassium.
3- The results indicate that NSOM is rich in theronine, methionine, isoleusine, phenylalanine and histidine and deficient in valine, leucine, lysine and arginine.
Biological Experiments
First trial
In this study twelve-individually caged adult Alexandria males were divided into two groups, starved for 24hr. and then forced-fed 30g of NSOM; the excreta avoided during the subsequent 48hr. were collected quantitatively, dried, weighted and analyzed.
The results were as follows:
1 T AAA values of NSOM being higher than that of AAAA.
2 The results of AME was 3185kcal/kg and the average of TME was 3900 kcal/kg.
Second trial
In this study, thirty 14-days old broiler chicks (Hubbard) \were used in this trial. They fed growth trial employing diets which provide more than the quantity of protein needed for maintenance but less than the required for optimum performance.
From the TPE experiment the results suggest that NSOM could be used as a protein source for chicks diet, but not to complete replacement of soybean meal protein.
Feeding trial
First trail
In this study 48, five-days old broiler chicks (Arbor Acres) were used. In this experiment chicks were randomly distributed into 12 replicates of 4 chicks. Nigella seed oil meal was added at the top of commercial diets (isonitrogenous and isocaIoric) at levels of 1, 2 and 3%.
The results were as follows:
I-Using NSOM as a feed additive in broiler diets did not cause any harmful effect on body weight through experiment periods.
2-Feed consumption showed no effect throughout the experimental periods or for the whole experimental period when compared to the control one the protein consumption for the whole experimental periods followed the same trend.
3-Adding 1% NSOM improved feed utilization by 9.46% , as compared to those fed NSOM free diet. Protein efficiency ratio showed the same response.
4- There were improvements in dressing percentage, that seemed clear in both breast and thigh meat percentages of the groups fed NSOM at different levels, although the difference was not significant.
5- Abdominal fat, liver, heart, gizzard, pancreas and intestinal length were insignificantly affected by NSOM as a feed additive.
6-Water holding capacity, plastics and thermal different levels of NSOM as a feed additive.
Second trial
In this study 96, one-day old broiler chicks (Arbor Acres) were used. In this experiment chicks were randomly distributed into 24 replicates of 4 chicks. Nigella seed oil meal protein replaced soybean meal protein at 0, 10, 20, 30, 40 and 50 %.
The results were as follows:
I-Body weight gain overall the experimental period showed no significant differences among various dietary treatment groups.
2-Using NSOM protein did not significantly affect feed consumption throughout the experimental periods or for the whole experimental period when compared to the control one, protein consumption showed similar trend.
3- There were some indications that feed conversion ratio and protein efficiency ratio improved with feeding 20% NSOM protein of SBM, that means that feed utilization was improved by 4.78% with feeding NSOM as a protein source.
4- There were no significant differences among the various levels of NSOM proteins as compared to the control diet in dressing, total edible parts and breast and thigh yield.
5-Abdorninal fat, liver, heart, gizzard, pancreas and intestinal length were not significantly affected by different protein sources.
6-Chemical and physical composition of boneless breast and thigh meats of broilers did not differ among treatments.
7-Net return was increased over the control by using over 10% of NSOM as alternative plant protein source.
8-Economic efficiency was improved when NSOM was fed, the best results was obtained when 20-40% of NSOM was replaced SBM protein.
In conclusion the results provide evidence about the possibility of using NSOM as a protein source for broiler chicks without loss in their regular performance.
