<p class="abstrak2">In this experiment, we investigate the effect of modified banana tuber meal (M-BTM) to substitute dietary maize in growing-finisher colored-feathered hybrid duck. One hundred and ninety six hybrid ducks (Pekin x Khaki Campbell) with 421.31 ± 0.183g body weight (BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replications per treatment. These dietary treatments were: NC (negative control; maize-soyabean-meal based diet), BTM25 (25% maize was replaced by M-BTM-), BTM50 (50% maize was replaced by M-BTM), BTM75 (75% maize was replaced by M-BTM), and BTM100 (100% maize was replaced by M-BTM). The experimental design applied using completely randomize design (CRD). Data of this experiment were statistically analysed by one-way-analysis-of-variance of SAS University version 4.0 red hat (64-bit) University Online Edition. Result demonstrated that M-BTM improved significantly (p&lt; 0.05) digestibility of dry matter and crude protein. It is concluded that M-BTM enhanced apparently growth performaces and digestibility parameters of colored-feathered hybrid duck (Pekin x Khaki Campbell).</p>

The Relationship

The data on 964 pig carcasses were examined with the objective to determine the relationship between a high carcass lean meat content in currently used pig hybrids and deterioration of the quality traits important for further processing of meat. The average slaughter weight of pigs was equal to 106.2 &plusmn; 0.417 kg. Lean meat percentage determined by the FOM instrument with the average value of 54.50 &plusmn; 0.139% was used as the main quantitative carcass trait. For the assessment of meat quality, the pH<sub>1</sub> value (average 6.15 &plusmn; 0.011) was used in the same way as in the system of breeding animals&rsquo; progeny testing. The relationship between the mentioned traits is characterised by the low correlation coefficient r = &ndash;0.13. This result was further confirmed by correlations determined between pH<sub>1</sub> and loin, shoulder and ham percentages (r = &ndash;0.33, r = &ndash;0.13 and r = &ndash;0.12, respectively). These relationships are rather surprising as the studies from the beginning and the first phase of realization of hybridisation programmes usually emphasized that the increasing lean meat content in carcass was connected with the higher incidence of negative side effects. Our conclusions are also in agreement with the results of the separate analysis of carcasses with pH<sub>1</sub> above 5.8 and equal to or lower than 5.8. The carcasses with pH<sub>1</sub> referring to less favourable technological properties of meat showed somewhat higher average values characterising carcass meat content but the differences between the groups were small and insignificant. We were not able to find any relationships between higher meat contents in carcasses and less favourable pH<sub>1</sub> values when the carcasses were classified according to meat content. &nbsp;

Data from a swine breed development project provided estimates of the genetic correlation among six performance and carcass traits. The data from the new breed, called Managra, were obtained over a 7-year period. Most genetic relationships examined were such that selection for improvement of one trait would yield a favorable improvement in another. Both carcass backfat and live backfat probe were found to be negatively correlated with area of loin eye and length of carcass. A positive genetic correlation was found between post-weaning daily gain and loin eye area. A high positive genetic correlation was found between birth weight and loin eye area. An unfavorable association involved a positive genetic correlation between birth weight and backfat.Correction factors for effect of carcass weight on the magnitude of carcass trait measurements and differences in means between sexes were obtained.Heritability of the traits was estimated by paternal half-sib correlation. The estimates for carcass traits were moderately high and agree well with most other estimates reported in the literature.
