“…And above all water, which is considered as the principal nutrient should be pure, wholesome, and free from physical impurities, toxic substances and bacterial contamination. The poultry contribute a good quota to Nigeria economy and employment opportunities creation [3][4][5]. It is therefore important that poultry farming be carried out efficiently for high productivity and sustainability of the industry in Nigeria.…”

The diet problem is a classic problem, one among the earliest problems formulated as a linear programming. The goal of the diet problem is to select a set of nutrients that will satisfy a set of daily nutritional requirement at minimum cost. Poultry being simple stomached species, cannot synthesize most of the nutrients required for them and so the nutrients become dietary essentials. Chicken has to be fed adequate quantities of balanced diet for its growth, livability and to exhibit its genetic potential to the full extent. Maximizing live bird profitability is similar to minimizing feed cost per kg live weight. The nutrient diet model formulation is a combination of different feed ingredients needed for a balance diet of the bird. The generic mathematical model which is applicable to each type of ration nine decision variables and ten parameters is constructed as subject to a set of twelve obtained constraints from a local farm. The model was solved using an excel solver package for easy accessibility. Model solution and post-optimality test results were obtained and compared with existing practice of the case study farm. The proposed optimal formulation of the linear programming model gives about 7.48% and 9.96% reduction in feed formulation costs compared to the existing formulation in case of broiler starter and finisher respectively on the farm. The model also reduced the amount of fat contained in the existing ration but adding more flesh by significantly increased the metabolisable energy needed for physiological structure. Post-optimality test or Sensitivity analysis also gave useful insight into the impact of changes in costs of feed inputs.

“…Poultry production has a major role to play in the economy of developing countries (Shaikh & Zala, 2011;Oladokun & Jonhson, 2012;Sambo et al, 2015) but the cost of feed is thwarting production (Casartelli, Filardi, Junqueira, Laurentiz, & Duarte, 2006;Moreki, 2011;Ja'afar-Furo & Gabdo, 2010;Ntuli & Oladele, 2013). Increasingly the deficit of traditional ingredients such as soyabean (Martens, Temann, Bendelle, Peters, & Lascano, 2012;Mutayoba, Dierenfed, Mercedes, Frances, & Knight, 2011), increasing trends of severe droughts (Sheffield & Wood, 2010) and competition for feed resources between humans and chickens (Ncube, Hamudikuwanda, & Banda, 2012a) continue to be blamed for high cost of poultry feeds.…”

The effect of A. angustissima leaf meal based diets on intestinal physiology and dressed carcass weight was investigated on 150 day old chicks. Three diets, 0, 5 and 10% A. angustissima were used in a three phase feeding programme. At days 14, 28 and 42, two birds from each replicate were slaughtered, dressed and weighed. The weights and lengths of the duodenum, jejunum and colon were measured. Approximately 1 cm specimen was taken from each organ, fixed in formalin and stained for histological analysis. Using a light microscopy, the digestive and absorptive properties of the tissues were assessed. Inclusion of A. angustissima leaf meal increased intestinal wall thickness, epithelial thickness, and villus height of the duodenum (P < 0.05). There was no effect on the proportional weight and length of the jejunum, jejunum villi height and villi width (P > 0.05) but jejunum wall thickness decreased with increasing levels of the leaf meal (P < 0.05). Leaf meal inclusion resulted in an increase in weight, intestinal wall and mucosal thickness of the colon (P < 0.05) and a decline in sub-mucosal fold height and haustra coli width of the colon (P < 0.05). Dressed weight was the same across diets at two weeks (P > 0.05). At four and six weeks, broilers on the control and 5% diet had superior dressed weights to the 10% fed broilers (P < 0.05). It was concluded that for intestinal physiological adaptation that will not compromise weight gain in broilers, up to 5% A. angustissima could be included in broiler diets.

“…However, major problems of poultry production in Nigeria are high cost of feed ingredients and feeds, poor quality feeds, high cost of day old chicks and poultry diseases (Akintunde & Adeoti, 2014). Feed cost accounted for 70% of the total costs of production for poultry in Nigeria (Oladokun & Johnson, 2012). In order to reduce the high cost of feeding the birds and at the same time maintain the quality of the feeds, there is need to feed the growing pullets with basil leaf supplement.…”

The performance and carcass characteristics of Growing Pullets (GP) fed basil leaf (Ocimum gratissimum) (OG) supplement was studied for 8 weeks using eighty-four 13 weeks old Nera Black GP. The birds were maintained on growers diet supplemented with 4 levels of basil leaves supplement(BLS) (0, 5, 10 and 15g/bird) for treatments A, B, C and D, respectively at 3 days interval throughout the period of experiment. Each treatment was replicated thrice with seven birds per replicate in a completely randomized block design. Treatment A served as control. The birds were fed the same growers diet. Feed and water were served ad-libitum. Data were subjected to Analysis of Variance (ANOVA) and comparisons made using Duncan's Multiple Range Test. The results of the experiment showed a significant (p<0.05) treatment effects in total feed intake, feed conversion ratio (FRC) and number of eggs laid, final live weight (FLW) and mean body weight gain (MBWG). Similar scenario was observed in dressed, breast, thigh, plucked weights and egg follicle formation. Birds in control had the highest total feed intake (TFI) (6671.55 g) and MBWG (523.84 g) compared to other treatments (B, C and D) whose values were 6644.27, 6640.29 and 6152.67 g for TFI and 483.34, 500.00 and 445.24 g for MBWG, respectively. The cost of feed consumed was best on birds fed 15gBLS (N353.04/bird) while the highest number of eggs laid was recorded in birds served 5 g(83) and 15gBLS (77) with reference to control (57). Birds served 5-15g BLS had increased liver weight (26.01, 25.01 and 27.42 g) compared to control (24.38 g), while those fed 15gBLS had reduced dressed weight (DW) (952.50 g). The best egg follicle formation was recorded on those served 5g BLS/bird. There was progressive reduction in MBWG, TFI and egg follicle with increasing weight of OG, unlike FRC and liver weight, which increased linearly. Therefore, the GP are recommended to be served 5-15gBLS/bird and later reduced to 5gBLS/bird at 3 days interval when the GP had come up to 15-20% in lay, in order to minimize further loss in weight and to improve egg follicle formation.
