The effect of nano Zn fitogenik addition on broiler diet to carcass traits, relative organ weights and haematological response

Carcass traits and relative organ weights of growing rabbits fed graded levels of processed (ash treated and rumen liquor fermented) kola nut (Cola nitida) pod husks (PKPH) were investigated. One hundred and twenty (120) weaner rabbits of mixed breeds (New-Zealand white × Chinchilla) of equal sexes and average body weight 525.46g were randomly allotted to four (4) dietary treatments at 0 (0.00 % PKPH), 10 (10 % PKPH), 20 (20 % PKPH), and 30 % (30 % PKPH) inclusion levels and designated as diets 1, 2, 3, and 4, respectively. Each treatment group was replicated ten (10) times with three (3) rabbits per replicate and was fed ad-libitum for 56 days. The highest slaughter weight (1813.80 g/r), dressing weight (1068.70 g/r) and dressing percentage (58.54 %) recorded in rabbits fed diet 3 (20% PKPH) were similar to those fed the control diet (0 % PKPH) and diet 2 (10% PKPH) but was significantly (P<0.05) higher than those fed diet 4 (30 % PKPH). The lungs, liver, kidney, heart, and spleen of the rabbits fed dietary treatments were not significantly influenced. It was concluded that processed kolanut pod husk had no deleterious effect on carcass and relative organs weight of weaner rabbits.

A four week study was conducted using 180 four weeks-old Abor acre broilers to determine the carcass traits and economics of production of finishing broilers fed cassava and yam peel meals as partial replacement for maize. They were randomly assigned to three treatment groups of 60 birds each. Each treatment group was replicated three times with twenty birds constituting a replicate. The three treatment groups were fed the three experimental diets in a completely randomized design (CRD) for 28 days. Feed and water were provided ad libitum for the period. Proximate composition results revealed that cassava and yam peel meals are rich in energy and minerals. Birds on diets T1 and T3 had similar (p > 0.05) final live and de-feathered weights, which were higher (p<0.05) than those on diet T2. Birds on diet T2 and T3 had the lower (p < 0.05) carcass weight than the birds on diet T1. There were no significant (p > 0.05) differences in the cut parts and organ weights, but there were significant differences in the dressing percentage of the birds across the treatments. Revenue generated per bird was influenced (p < 0.05) with T3 birds having better income. It was concluded that sun-dried yam peel meal can replace 20 percent maize in the finishing broiler diet without adverse effects on performance and at reduced cost of productionKeywords: poultry, agro waste, unconventional feedstuffs, production traits, roots and tubers

The aim of this study was to evaluate the effect of dietary supplementation with Agave fourcroydes powder on growth performance, carcass traits, organ weights, gut morphometry, and blood biochemistry in broiler rabbits. A total of 40 male rabbits (New Zealand × Californian) weaned at 35 d were randomly selected for a control diet (CD) and CD + 1.5% of A. fourcroydes powder, with 10 replicates and two rabbits per replicate. After 60 d, A. fourcroydes powder increased body weight, feed intake, and weight gain (P<0.05), without affecting feed conversion ratio and viability (P>0.05). Furthermore, this natural product did not affect the edible portions and the indicators determined in the Longissimus dorsi, nor the organ relative weights and the intestinal morphometry (P>0.05); however, a decrease in cecal pH was observed and consequently an increase in cecal beneficial bacteria (P<0.05) were found. Also, A. fourcroydes powder reduced (P<0.05) the serum concentration of glucose, harmful lipids, HDL and atherogenic index although without change for the ureic nitrogen, creatinine and VLDL (P>0.05). Agave fourcroydes powder as a zootechnical additive promoted better growth, in addition, it showed lipid-lowering and hypoglycemic effects, without modifying the edible portions and organs digestive.

Carcass traits and internal organs of one hundred and twenty, one day-old broiler chicksmaintained on different dosages of coffee weed leaf ethanolic extract for eight weeks werestudied. Five dosages (0, 25, 50, 75 and 100mL) of coffee weed leaf ethanolic extract(CWLEE) per litre of drinking water (T1 T2 , T3 , T4 and T5 ) were used. The birds were allocated \to the various treatment groups in a completely randomized design (CRD) with each treatment replicated three times (8 birds per replicate). Data on carcass traits revealed that live weight (2.50kg/bird), defeathered (2.30kg/bird) and eviscerated (2.00kg/bird) weights as well as dressing percentage (81.69%) were significantly (P<0.5) higher among birds on 50mL of CWLEE compared to those on other treatment groups. Similarly, the relative weights of drumstick (16.60%) and thigh (22.28%) were also significantly (P<0.05) better in broiler chickens administered 50mL CWLEE. Relative organ weights of broiler showed that weight of heart, lungs, gizzard, bursa, spleen and kidney were significantly (P < 0.05) influenced by the treatments. It is therefore inferred that birds administered 50mL CWLEE gave better carcass quality and functioning of the vital organs and therefore can be recommended for broiler chickens.
