A total 90 Vanaraja experimental birds were divided into three respective groups based on floor density viz., G1 (16 birds/m2), G2 (12 birds/m2) and G3 (8 birds/m2). No significant difference in average live weight and carcass weight was observed between groups. Average feed consumption, feed conversion ratio (FCR) and dressing percentage in G2 and G3 was significantly (P<0.05) higher as compared to G1. There were no significant effect (P>0.05) of stocking density in the carcass characteristics except the heart weight. There were non significant differences among groups for total protein, albumin, globulin and A:G ratio. Blood glucose was significantly (P>0.05) higher in group G1 as compared to G2 and G3. Blood cholesterol level increased with increase in stocking density but not significantly. Blood parameters eosinophil, monocyte, basophil counts and H:L ratio were not affected by the stocking density. Hb concentration increased non-significantly with increased stocking density. Vanaraja birds from 8 birds/m2 to 12 birds/m2 give the better growth performance, FCR and dressing percentage without change in blood biochemical and hematological indices.

An experiment was conducted with commercial broilers to investigate the effects of feeding citric acid, acetic acid and their combination on their performance and to determine the economic competence of using citric acid and acetic acid in broiler rations. A total number of 108 one day old straight run broiler chicks were distributed to four dietary treatments i.e. 0 % citric or acetic acid (A), 0.5% citric acid (B), 0.5% acetic acid (C) and their combinations 0.5% citric acid and 0.5% acetic acid (D). The birds were reared in cages. Body weight gains, feed conversion ratio (FCR), mortality, dressing yield and carcass characteristics were recorded. The performance showed significant increase in body weight gain (P<0.05) when compared with the control during 0-5 weeks of age on 0.5% citric acid (B). Feed consumption increased (P<0.05) at 2nd and 3rd weeks of age on 0.5% citric acid (B). Feed conversion was found higher (P<0.05) during 0-5 weeks of age in treatment B when compared to those of the other treatments. Carcass characteristics were not affected by dietary treatments. The highest mortality was found in treatment A and treatment C due to excessive hot. It may be concluded that use of 0.5% citric acid in the diet of broilers may have better performance in respect of live weight gain and feed conversion.

The purpose of this study was to determine the effect of adding coated sodium butyrate at various levels to the rations of laying hens on their performance, egg quality, and some blood parameters. In this study, a total of 72 laying hens at the age of 60 weeks were fed for 56 days with the control ration and the rations containing sodium butyrate at various levels (300, 600, and 1200 mg/kg). The study was carried out in 4 treatment groups, each with 6 replicates. As a result of the study, there was no statistically significant difference between the treatment groups in terms of live weight change, egg yield, feed consumption, feed conversion ratio, egg weight, and egg mass. The addition of sodium butyrate to the rations of laying hens did not have a statistically significant effect on the egg shell breaking strength, eggshell ratio, shell thickness, egg shape index, albumen-yolk index, damaged egg ratio, and egg yolk colour criteria (L*, a*, and b*). Whereas there was no statistically significant difference between the treatment groups in terms of the levels of cholesterol, HDL, albumin, Ca, and P; some statistically significant differences were observed in terms of the levels of serum globulin, total protein, and uric acid. Based on the findings of the study, it was concluded that there was no need to add sodium butyrate to the ration for improving the performance and egg quality in the laying hens at the age of 60 weeks.

In this study, Hubbard Red JA57 genotype, which growing slowly in mixed sex, were examined in indoor (KYS) and free-range raising systems (SYS). The study was carried out at the Kahramanmaraş Sutcu Imam University (KSU), Animal Production Application and Research Center for 12 weeks. Each treatment was represented by 3 groups containing 28 male chick (total 168 chick). During the indoor treatment, the chicks were raised in floor pens in a conventional house (3.7 birds/m2). In the free-range treatment, the chickens were housed in a similar indoor house (3.7 birds/m2); in addition, they also had a free-range clover paddock (0.9 bird/m2). All birds were provided with the same diets as ad-libitum. In two different raising systems; live weight, feed consumption, feed conversion ratio, survival rate, carcass and parts rates, edible giblets weight and rates, testicular weights and rates, rectal temperature and tonic immobility were examined. Results showed that the weekly feed conversion ratio was found to be significant at the 11th week and the additive feed conversion ratio at the 12th week. The difference between the groups in terms of rectal temperature and tonic immobility values, testicular weights and rates were found to be significant. In terms of average interaction; While the average rates of hot carcass, cold carcass, back, breast meat and neck were the same, the averages of thigh, bony breast and wing ratios were different. The highest mean abdominal fat rate was found in KYS females, the highest average gizzard rate in SYS females, the highest mean liver in KYS females, and the highest heart weight in SYS males.

This study evaluated the performance, carcass characteristics, and centesimal composition of the meat of intact and castrated lambs of the Santa Inês breed and of the crossbred animals: one-half Santa Inês × one-half Texel. Thirty-four lambs were used, nine intact and nine castrated males of the Santa Inês breed, and seven intact and nine castrated crossbred males, all aged between 6 and 7 mo and with an average live weight of 18.2 kg. The design was completely randomized in a 2 × 2 factorial (two crossing and two sexual conditions), with statistical analyses performed in the STAT version 9.4 program. There was a significant difference the Santa Inês and the Texel and Santa Inês crossbred animals in feed conversion and average daily gain, with superiority of the latter group. Castration of animals aged <12 mo had no significant effect on the performance and on the carcass traits of the Texel and Santa Inês crossbred animals, whereas the genotype had a great influence on weight gain and on subjective and quantitative carcass characteristics, demonstrating that crosses in sheep are needed to explore the complementarity of breeds, and heterosis is needed to achieve better performances and carcass characteristics.

Carcass Parameters

A study was carried out to evaluate growth performance and carcass characteristics of broiler birds fed with varying level of choline inclusion in their diets; T1 (control), T2 (10g/10kg) and T3 (20g/10kg). A total of 225 marshall broiler chicks were randomly divided into three (3) treatment group of 75 birds each. Each group was divided into five (5) replicates of fifteen (15) birds each laid in a completely randomized design. Feed and water was supplied ad-libitum and the experiment lasted for 49 days. The total feed intake (1316.75-14442.18) (24437.13-31999.76) for starter and finisher respectively, body weight gain (6227.30-8241.20) (10956.64-14182.96) for starter and finisher respectively, feed conversion ratio (1.73-2.26) (2.21-2.48) for starter and finisher respectively. Many (thigh, wings, back) of the carcass parameters measured were not significantly (p>0.05) affected by the treatments but significant difference (p<0.05) was observed in drum stick, breast and neck.  However, significant difference (p<0.05) was also observed in gizzard, liver and bile, heart, lungs, legs and head. There was significant difference (p<0.05) in primal cuts per live weight, primal cuts per dressed weight, organs per live weight and organs per dressed weight. In view of the results obtained, it can be concluded that treatment two (10g/10kg) performed better in terms of total body weight (TBW) and feed conversion ratio (FCR). Also in the carcass characteristics, treatment two performed better in terms of breast yield, drumstick, percentage of primal cuts from live weight (P/LW) and percentage of primal cuts from dressed weight.

Significance Level

To investigate the effect of graded level of acetic acid on the production performance and carcass characteristics of broiler, present study was conducted for a period of 35 days in a controlled shed. A total of 240 Cobb 500 day old broiler chicks were divided into four dietary treatment groups (T0, T1, T2 and T3), each group with three replications and each replication having 20 birds. Control group (T0) birds were fed with the basal diet without any acetic acid. Birds of T1, T2 and T3 group were treated with 0.1%, 0.2% and 0.3% acetic acid in drinking water, respectively along with basal diets. Recorded data were analysed in SPSS software by using ANOVA and significance level was considered as 5%. Results showed that, acetic acid has significantly (P<0.05) improved live weight, live weight gain, feed conversion ratio (FCR) and some meat characteristics (carcass weight, thigh weight and breast weight) of experimental broilers. However, there were no significant (P>0.05) differences were observed between control group and acetic acid treated groups of birds in terms of feed intake, dressing percentage, liver weight, heart weight and abdominal fat. Net profit was higher in birds treated with acetic acid than the control group and the best performances were observed in the birds treated with 0.3% acetic acid. Res. Agric., Livest.

The aim of this study was to evaluate the effect of two herbal spices as feed additives for finisher broilers. 120 5-week old birds were randomly assigned to four treatments in a completely randomized design. Each group was further subdivided into three replicates of 10 birds per replicate. Four experimental diets were formulated such that diet I (T1) which served as the control contained neither ginger nor garlic. Diets 2 (T2) and 3 (T3) contained 0.25% garlic and ginger respectively. Diet 4 (T4) contained a combination of 0.25% of garlic and ginger. Response parameters evaluated include weight gain, feed intake, feed conversion ratio, blood parameters and carcass characteristics. The experiment lasted for 35 days. Results showed that birds fed supplemented diets had significantly (P<0.05) higher body weight gain and superior feed conversion ratio than birds fed the control diet. There was no significant (P>0.05) difference in the feed consumption of the birds among the treatments. The hematological indices, serum biochemistry and carcass characteristics of the birds among the treatment were not significantly (P>0.05) influenced by the dietary treatments. The results of this study suggest that ginger and garlic can be included in broiler finisher diets without adversely affecting the performance of the birds.

Positive Effect

The experiment aimed to investigate effect of combination of probiotics and prebiotics on the performance and carcass characteristics of broilers at finishing phase. A total number of 300 day-old Anak broiler chicks were used to determine the response of broiler chicks to diets supplemented with probiotics (Bacillus cereus) and prebiotics (Mannose). The chicks were randomly allotted to four treatment groups of 75 birds with 25 birds per replicate in a completely randomized design. The four dietary treatments comprised 500ppm MOS; 250ppm B. cereus + 500ppm MOS; 500ppm B. cereus + 500ppm MOS and 750ppm B. cereus + 500ppm MOS, respectively. Results showed that feed conversion ratio decreased significantly (P< 0.05) from 1.21 for groups fed det supplemented with 250ppm B. cereus + 500ppm MOS to 1.05 for groups fed with 750ppm B. cereus + 500ppm MOS  as more prebiotics were added to the probiotics. Final live weight, eviscerated weight and dressing percentage were significantly (p<0.05) influenced by combination of probiotics and prebiotics in finishing broilers. Final live weight values ranged from 2453.30g in birds fed 250ppm B. cereus + 500ppm MOS  to 2488.30g in birds fed 750ppm B. cereus  + 500ppm MOS, while eviscerated weight ranged from 1063.30g at 500ppm MOS to 1396.70g  at 750ppm B. cereus + 500ppm MOS. The same trend was observed for dressing percentage, neck, whole gizzard and liver. It was concluded that combination of probitics and prebiotics at 750ppm B. cereus + 500ppm MOS had positive effect on growth performance and carcass qualities of broilers at finishing phase.

  The study was conducted to determine the effect of graded levels of differently processed Roselle (Hibiscus sabdariffa) seed meal on the performance and carcass characteristics of broiler chickens. One hundred and fifty (150), 28-day old birds were randomly allotted to 5 dietary treatments of 3 replicates of thirty birds each. Each replicate had 10 birds. The treatments were: T1 - control diet with 0% inclusion level of Roselle Seed Meal (RSM) while the four other diets had 50% of raw (T2: rRSM), soaked (T3: sRSM), boiled (T4: bRSM) and  fermented (T5: fRSM) Roselle Seed Meal in a complete randomized design. At the end of the 28thday of the feeding (week 8), parameters measured were on performance and carcass characteristics. The data collected were analyzed using ANOVA of SAS with the means, where significant, were separated using the Duncan's Multiple Range Test. Final weight (FW) and weight gain (WG) were highest in birds on T5. Birds on T5 had the least feed conversion ratio (FCR) value (2.62). Feed intake and percent mortality did not differ significantly among birds on the different dietary treatments. Birds on T5 had significantly (p < 0.05) higher values for live weight (LW), thigh weight (TW) and neck weight (NW). Percentage eviscerated weight, breast weight, drumstick weight, shank weight, wing weight and back weight did not differ significantly among the birds on the different treatments. The gizzard (G), liver (L) and spleen (S) had the highest values in birds on T3 (G: 2.53%), T1 (L: 2.34%), T5 (S: 0.18) being significantly (p<0.05) different from T 5 (G: 2.04% and L: 1.87%), T2 (S: 0.08%), T3 (S: 0.08%) and T4 (S: 0.09%) respectively. There were no significant (p>0.05) differences observed among the treatments for percentage heart weight. It can be concluded that processing methods enhanced the utilization of Roselle seed meal with the best being the fermentation method as revealed by its feed conversion ratio, live weight and some carcass parameters when Roselle Seed Meal was substituted for 50% of soybean meal in the broiler finisher diets.
