Carcass and Organ Characteristics of Growing Japanese Quails (Cotintestineurnix Coturnix Japonica) Fed Sun-Dried Mango (Mangifera Spp) Kernel Meal (Published)

A study using complete randomized design (CRD) was carried out to assess the effect of Sun-dried Mango Kernel Meal (SMKM) on the carcass and organs characteristics of growing Japanese quails (Coturnix   coturnix    japonica). One hundred and forty four unsexed Japanese quails of about three weeks old were randomly selected and grouped into three treatments containing SMKM that replaced maize at 0%, 25% and 50% (TI, TII and TIII respectively) in properly compounded experimental diets. Each treatment was replicated thrice with sixteen (16) quails per replicate. The results of this study showed that SMKM did not influence the terminal live weights, carcass, dressed and neck weights of quails. In terms of organ weights, it was observed that SMKM affected the lungs, heart and kidney weights significantly (P<0.05) across  treatments. The relative organs weights showed significant (P<0.05) differences in heart, intestine, lungs and kidney weights but the reverse was with the gizzard and liver weights. However, the relative weights of drum stick,back  and breast muscles were significantly (P<0.05) different across treatments. It is concluded that sun-dried mango kernel meal could replace maize up to 50% in quails’ diets, however, choice cut-part of quails were  compromised.!

Carcass and organ characteristics of growing Japanese quails (coturnix coturnix japonica) fed diets containing boiled Prosopis africana seed coat meal (BPASCM) (Published)

This study aimed to evaluate the effect of replacing maize with boiled-toasted Prosopis africana seed coat meal on carcass and organ characteristics of Japanese quails. A total of three hundred (300) two-weeks-old unsexed Japanese quails were used in a seven week study. The quails were balanced for weight and equally allotted into five treatment groups of 60 birds per treatment. The control diet which contained 0% BPASCM and four other experimental diets in which maize was replaced by boiled Prosopis africana seed coat meal at 25%, 50%, 75% and 100% levels in the experimental diets constituted the five treatments (I-V) respectively. Result showed a significant (P<0.05) difference in the live weight, slaughter weight, dressed weight, breast weight, drum stick weight, back weight, shank weight and feather weight. The highest weight for all the carcass traits occurred in the control diet but was statistically similar to weights obtained in treatment group two. Organs such as intestine weight, liver weight, kidney weight, and heart weight were found to be significantly (P<0.05) affected by the replacement with boiled Prosopis africana  seed coat meal  (BPASCM) while others such as lungs weight, spleen weight, pancreases weight and gizzard weight were not significantly (P>0.05) influenced by replacement with BPASCM The highest weight of intestine was observed at treatment V. Liver weight and heart weight were highest in treatment II and the highest weight of kidney was recorded in the control group. The inclusion of both maize and BPASCM in the diets at 3:1 ratio respectively is recommended in the feeding of meat-type Japanese quail birds.
