Abstract The present trial explained the effect of alternative production systems on growth, morphometric and carcass traits of four different chicken genotypes. The second generation of two genotypes RNN (Rhode Island Red × Naked Neck) and BNN (Black Australorp × Naked Neck) obtained by two self-crosses (RNN × RNN = RR and BNN × BNN = BB) and two reciprocal crosses (RNN × BNN = RB and BNN × RNN = BR) were evaluated in three alternative production systems (conventional cages, enriched cages, and aviary). At the 6th week of age after sexing, a total of 600 birds, comprising 150 from each crossbred with a total of 300 pullets and 300 cockerels were divided into conventional cages, enriched cages, and aviary systems having 200 birds in each.Birds were organized into 3×4 factorial arrangements under Completely Randomized Design (3 production systems × 4 genotypes × 2 sexes × 25 birds = 600 birds). Regarding genotypes, RB and BR males showed higher (p < 0.01) carcass yield, drumstick weight, breast weight, and thigh weight than BB and RR genotypes. Females of BR genotype showed higher (p < 0.01) breast weight, thigh weight and drumstick weight. As far as production systems are concerned, higher (p < 0.01) liver weight, heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight were observed in the males reared in enriched cages compared with conventional cages and aviary system. Females reared in enriched cages showed higher (p < 0.01) heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight when compared with those reared in conventional cages and aviary. It is concluded that chickens (both sexes) of BR and RB genotypes had better morphological measurements and carcass traits than those of RR and BB genotype chickens. Among alternative production systems, chickens reared in enriched cages had better traits than those of reared in conventional cages and aviary during the growing phase.

Feeding Regimen

To evaluate the effect of a production system and feeding regimen on meat quality attributes of Naked Neck chickens, a total of 150 cockerels at 18 weeks old (1625 ± 70 g) were collected from 10 treatment groups with five replicates of three birds. The factorial arrangement of treatments consisted of two production systems (intensive and free-range) and five nutritional regimens, namely 100% commercial feed; 75% commercial feed plus 25% kitchen waste; 50% commercial feed plus 50% kitchen waste; 25% commercial feed plus 75% kitchen waste; and 100% kitchen waste. Carcass traits, meat quality, and meat organoleptic were found to differ significantly among production systems, feeding regimens, and their interaction. Higher liver weight was observed in birds reared under an intensive system. Higher gizzard weight was noted in birds fed with 100% kitchen waste, whereas lower gizzard weight was observed in birds fed the commercial diet. The meat from cockerels fed with 75% kitchen waste was most yellow, whereas the meat from the birds fed with 100% kitchen waste was least yellow. At two hours after slaughter, pH of the meat was highest in birds fed 50% kitchen waste and lowest in birds fed 100% kitchen waste. The interaction of production system and feeding regimen was significant for overall acceptability score. In conclusion, Naked Neck chickens performed equally well under intensive and free-range systems, irrespective of the level of kitchen waste that they were fed.

Effect Of Feeding

A five-week study was conducted to determine the effect of feeding varying levels of S. cerevisiae on carcass and organ characteristics of finishing broilers. One hundred and twenty 4-weeks old broilers of cobb strain were randomly assigned to four treatments (T1 = 0.6 g Saccharomyces cerevisiae (SC) kg–1 diet; T2 = 0.8 g SC kg–1 diet; T3 = 1.0 g SC kg–1 diet and T4 = 0.0 g SC kg–1 diet) with 30 birds per treatment and replicated twice with 15 birds per replicate in a completely randomized design. Feed and water were provided ad libitum to the birds in a deep litter system. In the end, data on growth, carcass and organ indices generated from the study were analyzed using one-way analysis of variance (ANOVA). Results showed no significant difference (p > 0.05) among the treatments in the birds’ growth performance indices. However, significant differences (p < 0.05) were observed in the birds’ values for liver weight, heart weight, shank length and thigh length with birds in T3 recording highest values of 61.30 g, 16.93 g and 12.00 cm for liver weight, heart weight and thigh length, respectively. It was thus concluded that finishing broilers fed 1.0 g of S. cerevisiae had superior carcass and organ characteristics than birds on the control and lower levels of inclusion.

INTERNAL ORGANS CHAR ACTERISTICS OF NATIVE CHICKEN FED BY COCONUT OIL (Cocos nucifera) ON DIET. The research was carried to determine the internal organs characteristics of buras chickens fed coconut (Cocos mucifera) oil in diet. A total 100 unsexed buras chickens was used in this experiment. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 5 replications (4 hens each). The data were subjected to analysis of variance, when the treatments indicated significant effect it was continued Duncan’s Multiple Range Test. Five dietary treatments containing 0, 0.5%, 1 %, 1,5%, and 2% levels of coconut oil (CO) with five replicates were applied to chickens.  Parameters measured were body weight, heart, liver, pancreas  and gizzard weight. Result showed that CO in the ration significantly increased the body weight (P<0.01) but did not affect to heart weight, liver weight, pancreas weight and gizzard weight.(P>0.05) It can be concluded that coconut oil in the diet can’t increase the internal organ characteristics. We can gave the 2% CO in the diet for the best results. Key words: Internal Organs, Coconut Oil, Buras Chickens

The effects of the production system, breed cross, and their interaction on performance, egg quality, and hatching traits were evaluated. Rhode Island Red and Black Australorp were crossed with Naked Neck chickens (first generation RNN, and BNN, respectively). These crosses were mated among themselves and crossed to produce four crossbreds: RR (RNN x RNN), BB (BNN x BNN), RB (RNN x BNN), and BR (BNN x RNN). Thirty-six pullets and 9 cockerels from each crossbred were maintained in three production systems: the aviary system (AV), conventional cages (CC), and enriched cages (EC). Thus there were 48 pullets and 12 cockerels in each production system. Bodyweight, egg production percentage, and egg weight were highest in EC, followed by CC and AV. Higher egg weight, egg surface area, and egg volume were also observed in EC compared with CC and AV. Fertility and hatchability were higher and early embryonic mortality was lower in AV than in EC and CC. Bodyweight, egg production percentage, egg weight, egg volume, and surface area were higher for RB and BR than for BB and RR. Fertility and hatchability were similar for RB and BR. RR was similar to BR, but lower than RB. BB had the lowest fertility and hatchability. Thus, chickens in EC performed better than in the other systems, except that hatching traits were better in AV. RB and BR performed better than BB and RR.Key words: breed crosses, chicken, egg quality, hatchability

Different Levels

The objective of this work was to evaluate the utilization of methionine from DL-methionine (DL-Met) and L-methionine (L-Met) with different levels of dietary methionine plus cystine (Met + Cyst) in broilers. The experimental diets were formulated by using three levels of Met + Cyst, i.e., 74%, 77% and 80% of digestible lysine. Met + Cyst was provided either from DL-Met or L-Met. A total of 450 day-old broilers were divided into six groups (five replicates of 15 birds each) in a 3 × 2 factorial arrangement under completely randomized design. Weight gain (WG), feed intake (FI) and feed conversion ratio (FCR) was determined. At the end of the experiment (35 days), two birds from each replicate were slaughtered to determine carcass characteristics and serum homocysteine. Results indicate that the combined effect of L-Met and DL-Met significantly affected (p < 0.05) the WG in the starter period and FI in the finisher period. Neither source nor level of methionine influenced (p > 0.05) the FI, WG and FCR of broilers during the starter, finisher or overall phase of growth. The interaction between sources and levels of methionine did not influence (p > 0.05) the feed intake, weight gain and FCR during the overall phase of growth. Source of methionine had no (p > 0.05) effect on carcass characteristics. Methionine levels had a significant effect (p < 0.05) on carcass weight, chest weight and thigh weight. The interaction between sources and levels of methionine had a significant (p < 0.05) effect on the liver weight. The sources of methionine had significant (p < 0.05) effects on the liver and heart weight, while methionine levels significantly influenced (p < 0.05) the liver and gizzard weight. Finally, it was concluded that if DL-Met and L-Met are included in feed at a standard level, they are equally effective as a source of methionine for broilers.

Examining effect of Strain on External and Internal Egg Parameters of Rhode Island Red (RIR), two Nigerian indigenous chicken strain:-(Pure naked neck (NNK); pure Normal feathered (NF)); Crosses were:- RIR x naked neck (RNK) cross; RIR x Normal feathered (RNF) cross. Matured 100 birds reared intensively for 10 weeks at Teaching and Research farm, University of Uyo in a Completely Randomized Design in standard management practices. Feed (16.0% crude protein, 2800 Kcal/Kg Metabolize-able energy) and water given ad libitum. 10 eggs per strain were cracked every Mondays and Fridays every week to examined External (egg weight(Ewt), egg length(El), shell weight (Swt) and Internal (yolk height (Yht), yolk weight(Ywt), albumen weight(Awt) albumen height  (Aht) and Haugh unit (HU)) egg parameters. All data were subjected to one-way Analysis of Variance of SAS Statistical Software Package Version 9.2. Results indicated significant (P<0.05) effect of strain on external egg parameters studied. For Ewt, RNK (46.38±0.79 g) and RNF (45.54±0.96 g) were statistically (P<.05) higher than NF (42.42±0.85 g). For Swt, RNF(4.71g±0.09 g) was statistically (P<.05) higher than NF (4.36±0.11g) but similar in other strains. Result indicated significant (P<0.05) effect of strain on all the internal egg parameters measured. For Hu (RNK) 79.08±1.23% and (RNF) 77.83±1.88 were statistically (P<.05) higher than (NF) 73.84±1.10%. The same trend followed in other internal egg parameters among the strains. Generally, the trends placed were exotic birds first, then Crossbreds and Purebreds last in the parameters. In conclusion, RNK and SNF crossbreds performed better in both External and Internal egg parameter than purebred strains studied. Hence, crossbreeding should be adopted to improve Nigerian Chickens.

Myostatin (MSTN) is a well-known negative regulator of skeletal muscle mass, and MSTN inhibition is being considered as therapy for multiple conditions associated with muscle wasting, including sarcopenia of aging. We have previously shown that MSTN inhibits phenylephrine-induced cardiomyocyte hypertrophy, however whether MSTN has a physiological role in regulating cardiac hypertrophy or function at baseline or with aging remains unclear. To determine if MSTN is dynamically regulated with aging, we performed QRT-PCR on hearts from male wild-type (WT) senescent mice (24 months old (mos)) and rats (32 mos). MSTN mRNA levels were increased in old versus young (4 mos) hearts (2.5- and 4-fold respectively, p<0.05). To study the functional significance of MSTN in aging, we maintained germline MSTN-knockout mice (MSTN −/− ) and their WT littermates for 24 –27 months. We found no difference in heart weight of aged male MSTN −/− compared to WT mice (162.5±17.0 (n=4) vs 153.2±4.2 (n=4) mg, p=0.51), which would argue against an inhibitory role for MSTN in age-related increases in cardiac mass. We also performed echocardiography on unanesthetized senescent MSTN −/− and WT mice. MSTN −/− mice had better fractional shortening (58.1±2.0 (n=7) vs 49.4±1.2 (n=8) %, p=0.002) and smaller LV end-diastolic diameter (3.41±0.19 vs 2.71±0.14 mm, p=0.012) compared to WT. The decreased cardiac function seen in aged WT mice was associated with increased cardiac fibrosis on Masson-Trichrome stained sections. Western blot analysis also demonstrated a 3.3-fold increase in phospholamban phosphorylation in MSTN −/− hearts (p<0.05), compared to WT, while no differences in SERCA2a or calsequestrin protein levels were seen. We conclude that MSTN increases in the heart with aging, and that genetic deletion of MSTN results in improved cardiac function without a difference in heart mass in senescent mice. Decreased cardiac fibrosis and increased inhibition (phosphorylation) of phospholamban likely contribute to the better cardiac function seen in senescent MSTN −/− mice. These results suggest that inhibiting MSTN for sarcopenia in the elderly may also benefit cardiac function and could represent a novel therapeutic approach for ameliorating cardiac dysfunction and/or fibrosis.
