Feeding Palm Oil On The Productive And Economic
Performance Of Broiler Chickens
The use of 7% palm oil slurry reduces the feed cost of broiler production compared to the control by approximately 17%; this new feed source for broilers could be a high-cost solution for poultry feed in forested areas where the production of large quantities of palm oil-related to the development of oil palm plantations releases large quantities of waste ; It seems necessary to determine the storage time and the different methods of conservation of food containing at least 7% of palm oil sludge because, their content of water and fat, factors favourable to the oxidation is very high. Palm offers its benefits not only in chicks but also in many others. To know more about palm oil uses, visit https://russalgear.com/palm.
Poultry production in Cameroon suffers from high food costs that account for about 60-70% of production costs. To this end, it is urgent to look for new inexpensive, unconventional and unmanaged sources of food such as exist in forest areas. As part of the optimisation of new poultry feed resources, our focus was on palm oil sludge given its availability.
It is a residue of the clarification of palm oil in production units, of a greasy and yellowish nature, which is currently spilled in nature and is a source of pollution. Tests on the use of palm oil sludge in poultry feed are limited or non-existent in Cameroon. However, the development of oil palm plantations in the forest zone of Cameroon leads to the production of large quantities of palm oil: 8750 tons in the Center, and, consequently, enormous quantities of oil palm. wastes (oil sludge, fibers, palm kernel husks …) with little or no value.
Maize or palm oil which enter the rations of poultry as main energy sources and whose use is limited by their high demand for both food and feed could finally be partly substituted by palm oil sludge. The objective is therefore to describe the effects of palm oil sludge in diets on dietary intake, weight gain, feed efficiency, carcass yield and economic performance of chickens. of flesh in the finishing phase.
Material and Method
A total of 384 (50% male and 50% female) 30-day-old chicks have experimented. These chicks received sanitary coverage in force in the area during the start-up phase; these are vaccinations against viral diseases such as: Gumboro disease, pseudo avian plague, infectious bronchitis and preventive treatments against coccidiosis.
Conduct of the test
The chicks randomly distributed in 12 boxes on the litter of wood chips, received a watering at will and were subjected to 4 treatments corresponding to the rations containing 0.3, 5 and 7% of the palm oil sludge. Each treatment included 3 repetitions of 32 chicks each (1/2 males and 1/2 females). The experimental rations were iso-protein (about 22% crude protein), with metabolizable energy levels ranging from 3051 to 3264 kcal/kg. The chemical characteristics of the rations were calculated from the chemical composition of the raw materials and the chemical composition of the palm oil sludge.
Unmeasured lysine, methionine, calcium and phosphorus values of the sludge. Before the start of the trial, a 3-day adaptation period during which chickens consumed test foods and drinking water was observed. Feeding was done at will during periods of natural lighting during the test. Weekly weighings were adopted from the first day for chicks, feeds and refusals. Mortalities were recorded daily. At the end of the trial, 4 randomly selected chickens (2 males and 2 females) in each replicate were slaughtered after 24 hours of fasting to determine carcass characteristics. Emphasis was placed on abdominal fat, gizzard, liver, heart, plucked carcass, emptied carcass, and cooled carcass. All these parameters were expressed as a percentage of live weight.
The price of the kilogram of food has been determined from the price of raw materials available on the local market. The feed cost per kg live weight of chicken was estimated by multiplying the price of kg of feed by the consumption index defined as the ratio of food consumed to weight gain.
Chemical composition of palm oil sludge
The lipid content is higher than that of maize and quite close to that of palm oil, but its cellulose content is higher than that of maize; its dry matter content is very low compared to that of maize.
The total weight gain increased from 1041 ± 24 g for the control diet to 1468 ± 100 g for the 7% palm oil sludge diet, with significantly higher values starting at 5% incorporation. This difference in weight growth is related to a significant (p <0.05) dietary intake from 3% incorporation of palm oil sludge into the ration; regardless of the level of incorporation, the use of rations containing palm oil sludge results in a greater weight gain compared to the control.
The consumption indices of the chickens fed the 5% and 7% palm oil sludge diets were significantly (p <0.05) better than those of the 0% and 3% rations containing chickens.
Food cost of production per kilogram of live weight
The food cost of producing one kilogram of live weight decreased progressively from the control diet to the ration containing 7% palm oil sludge, with significantly lower values from the diet containing 5% sludge.
Incorporation of 7% palm oil sludge into finishing broiler diets results in greater weight gain compared to the control. This new feed source significantly reduces the cost of food production. broiler chickens in the finishing phase (about 17%), and could be exploited very successfully during periods when maize, which is the main source of energy in poultry diets, is very expensive. It is also a way to preserve this cereal to reduce competition between humans and poultry for its use.
However, the practical problems associated with the incorporation of this very water-rich residue remain. The preservation of foods containing a high percentage of oil sludge is difficult.
It deviates imperative to determine the time and the different methods of conservation of the food containing at least 7% of palm oil mud in the perspective of avoiding serving.
