The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...

in order to determine the optimal levels of energy and protein in grower diet of japanese quail, 360 dayold japanese quails were used in a 3×3 factorial arrangement of dietary treatments that comprised threelevels of metabolisable energy (2750, 2850, and 2950 kcal/kg) and three levels of crude protein (24, 26and 28 percent) with four replicates per treatment in a completely randomized design. f...

The haematological and serum biochemical responses of broilers fed indomie waste-based diets (IWBD) were investigated using one hundred and ninety (180) day-old broiler chicks of Anak strain. The chicks were randomly allotted to the different dietary treatments having graded levels of the IWBD in a Completely Randomized Design (CRD). Each treatment contained 3 replicates and each replicate had ...

Broilers were allocated to eight treatments consisting of two energy levels: normal (NE) and high (HE), four folic acid (FA) levels (2.2, 5, 10, 15 ppm). On day 42, male female chickens euthanized per pen, white striping (WS) evaluation was performed on the pectoralis major. Birds fed HE diets had reduced (P < 0.05) feed intake conversion rate than those NE diets. With increasing FA levels, ...

One hundred and eighty 28-days-old Arbor Acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. Five experimental diets tagged T1, T2, T3, T4 and T5 were formulated to be isocaloric (2865.53 kcal ME/kg) and isonitrogenous (20% crude protein) suc...

Twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. Treatments consisted of 8 (T1), 4 (T2) or 2 (T3) feeding buckets/pen (8 lambs/pen). During the experiment, concentrate was fed at 08:30 in individual feeders. Daily dry matter intake (DMI...
