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.

An experiment was conducted from 18th October, 2006 to 18th January, 2007 at IAAS Livestock Farm, Rampur, Chitwan to determine the substitution effects of soybean meal with brewer's dried grain (BDG) on the performance, economics and meat traits of swine production. Starter, grower and finisher diets were formulated containing 18, 16, and 14% CP respectively with 3000 Kcal/kg ME and adequately supplemented with required vitamins, minerals and amino acids. The treatments were: diet without brewer's dried grain -T1 (control diet), diet substituted with 10% brewer's dried grain-T2, diet substituted with 20% brewer's dried grain-T3, diet substituted with 30% brewer's dried grain-T4 and diet substituted with 35% brewer's dried grain-T5. Twenty weaned piglets having 7.37 to 7.94 kg live weight were housed in individual pens. Five piglets were randomly assigned to the five treatments following a randomized complete block design (RCBD) considering each individual as a replication. Fortnightly live weight, daily feed consumption, income over feed and pig cost, and different meat traits of pigs were recorded. The effect of replacing formulated diets with various level of brewer's dried grains on body weight gain was significant (p<0.01) with higher level of substitution resulting lower live-weight at the end of each of starter, grower and finisher diet period. The average body weight of piglets substituted with 35%BDG (27.00kg) and 30%BDG (39.75kg) were significantly lower (p<0.01) compared to the weight of piglets receiving 0% (65.75kg), 10% (64.25kg) and 20% (60.25kg) BDG replaced diets at the end of 3 months experimental period. A significant reduction (P<0.01) in average daily feed consumption were also recorded with increasing level of BDG in the diet. Better feed conversion ratio (FCR) was observed in T2 at early period which at finisher stage T3 diet resulted significantly better FCR which was at par with T1 and T2 diet fed group. However, T5 diet resulted the poorest feed conversion ratio of 5.26, 4.92 and 5.87 for starter, grower and finisher respectively. There was reduction in feed cost with different levels of BDG substitution in diet of pig. Highest income (in per cent) over expenditure (109.01%) was found in T2 followed by T1, T3, and T4. Lowest income over expenditure (-8.2%) was found in T5. Highest dressing percent (71.87%) was recorded in T1 and lowest (70%) in T5 diet fed group. Inclusion of 10-20% BDG seems most acceptable level of substitution of SBM. However, this result needs to be verified under farmer's management condition before recommendation.Key words: Brewer's dried grains; Swine performanceDOI: 10.3126/njst.v10i0.2820 Nepal Journal of Science and Technology Volume 10, 2009 December Page: 29-35

Research aimed to determine broiler performance fed different level of yoghurt - fermented pineapple peel (FPPM) in the diet containing medicinal weed. Two hundred 2 day - old male broiler chicken, diet containing medicinal weed  (MW) and yoghurt - fermented pineapple peel used in this study. The experimental design was a completely randomized design with 5 treatments and 5 replications. The treatments were T0 (control, diet containing 0% FPPM and 0% MW), T1 (diet containing 0% FPPM and 2% MW), T2 (diet containing 7.5% FPPM and 2% MW), T3 (diet containing 15% FPPM and 2% MW), and T4 (diet containing 22.5% FPPM and 2% MW). The variables were feed consumption, body weight gain, live weight and feed conversion ratio. Data were analyzed by ANOVA and Contrast orthogonal Test. The results showed that there was a significant effect (P<0,05) of treatment on the feed consumption, body weight gain, live weight and feed conversion ratio. Feed consumption and feed conversion ratio increased with increasing level of FPPM in the diet, however, body weight decreased. It is concluded that feeding yoghurt - fermented pineapple peels up to 22,5 % in the broiler diet containing medicinal weed decreased broiler chicken performance.

In this paper are presented the growth performances (live weight, average daily weight gain, feed consumption and feed conversion ratio) of broilers Hybro G+ provenience. Feeding, zoohygienic and zootechnical measures met technological normative for this provenience. Broilers were fed with the complete feed mixtures (producer ?Dren?, Novi Sad) with added anticoccidial salinomycine in the amount of 66 mg/kg up to 35. day of fattening. In last week of the fattening period, salinomycine was not added (drug waiting period is 5 days). Live weight of broilers at the end of trial was 1959.74 g to 2750.48 g (average 2340.62 g). During the fattening period, average daily weight gain was 54.70 ? 5.03 g; it was in the range 45.71-64.39 g. Average daily feed consumption was 87.97 g for all fattening period and feed conversion ratio was 87.97 g.

Phosphorus Levels

The experiment was conducted to study whether wheat bran (WB) phytase could improve the availability of intrinsic phosphorus (P) in commercial barley-soybean meal diets enough to replace the added inorganic P partly or completely in the diets of growing-finishing pigs (30-100 kg). Performance as well as certain chemical and physical parameters of the tibia and fibula bones were used as criteria for the WB phytase effect. The experiment was conducted using a 2x3 factorial arrangement. The factors were wheat bran (WB) level - either 0 (WB-) or 100 g/kg (WB+), and phosphorus level - high (HP), medium (MP) and low (LP) corresponding to 4.33 g, 2.99 g and 1.64 g digestible P per a feed unit (FU = 0.7 kg starch equivalent), respectively. The measured digestible P contents of the diets were 4.2, 4.2, 2.7, 2.5, 1.4 and 1.8 g/kg DM, respectively. A content of 2.5-2.7 g of digestible P/kg DM in the diet proved to be sufficient for the whole growing period, but the lowest phosphorus levels led to an impaired growth rate, feed consumption and feed conversion ratio. However, after reaching 60 kg live weight, the pigs on LPWB- and LPWB+ diets were able to grow and utilize feed as effectively as the other pigs. WB at a level of 100 g/kg had no significant effect on the performance, feed conversion ratio or carcass quality criteria of the pigs on any diet. WB phytase showed a positive effect on bone breaking strength on the LP diet.

Weight Groups

This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits of Lohmann hens, 24 weeks of age, in different laying periods. A total of 288 Lohmann White layers were allocated randomly to three groups with respect to live weight, each consisting of 24 replicated cages as subgroups, comprising four hens. The study period lasting for 60 weeks was investigated as four different age periods (first period = 24–40 weeks; second period = 40–54 weeks; third period = 54–68 weeks; fourth period = 68–84 weeks). Differences in the initial live weight at the beginning of experiment among the groups continued to the end of experimental period. Considering the egg production, differences among the groups were not significant (<I>P</I> > 0.05) during the experimental period. Egg weight was determined to be lower in the group with low body weight (64.58 g) than in medium (64.97 g) and heavy hen groups (66.30 g). Differences in feed intake and feed conversion ratio among the groups were found significant, and the mean values were 123.93, 127.48 and 130.67 for feed consumption (g/day); 2.23, 2.28 and 2.27 for feed conversion ratio. Except for the feed conversion ratio, the effect of weight groups by age period interaction on performance parameters was significant (<I>P</I> < 0.01). The effects of body weight on shell strength, shell thickness and yolk index were not significant during the experimental period. However, different body weight groups significantly affected shape index, yolk colour, albumen index and Haugh unit parameters. Shell strength, yolk colour and yolk index values were affected by weight groups by age period interaction. In conclusion, Lohmann White hens in the light group in a uniform flock had higher egg production and lower feed conversion ratio values than those of other weight groups.

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.

Maintenance Requirements

Relationships between the intake of energy and the rate of gain on the one hand, and the chemical composition of gain on the other were studied in bacon pigs, assuming that: (1) the only important determinants of the energy balance are the expenditures of energy in maintenance, in protein deposition and in fat deposition; (2) the net energy cost of fat or of protein deposition remains constant in pigs of all ages and live-weights, whatever the level of nutrition; (3) the average maintenance requirements of pigs growing over the same live-weight range and kept under similar conditions are constant, irrespective of their daily gains; (4) the ratio of non-fat components to protein in the gains of pigs over a similar live-weight range is virtually constant. Deductions based on these assumptions enabled the expression of the feed conversion ratio as a function of the average daily protein deposition, the average daily maintenance requirements and the average daily intake of energy to be made. The dependence of the feed conversion ratio on each of these three factors was demonstrated.After the substitution of plausible values for the energy costs of protein and of fat deposition, as well as for the average maintenance requirements, equations were derived for the estimation of the content of protein and of fat in the live-weight gain, when the total feed consumption and the number of days on test (20 to 90 kg.) were known. Using these equations, the average gain of fat and of protein in each year were estimated for the Danish Progeny Testing Stations during the period from 1926–7 to 1962–3. It was found that the decrease of the feed conversion ratio and consequent reduction in fat deposition which were achieved during this period, were accounted for mainly by an increase in daily protein deposition.

Abstract. This research was conducted to evaluate the effects of plastic slatted floors and a deep-litter system using wood shavings on the growth performance of current commercial hybrid Pekin ducks. A total of 96 Pekin ducks (Star 53) were reared for 42 d. Live weight, live-weight gain, feed consumption, feed conversion ratio, water consumption, and water ∕ feed consumption ratio were investigated as the performance criteria. With the use of plastic slatted floors, the feed conversion rate dropped and the water ∕ feed consumption ratio showed an incline (p<0.05). This is a very favourable result for the poultry industry and growers. The remaining parameters did not change by altering the ground system (p>0.05). Generally, it can be stated that plastic slatted floor use has advantages concerning the performance criteria of the feed consumption ratio and the water ∕ feed consumption ratio in comparison to the deep-litter system. Furthermore, improvement in the feed conversion ratio is known to benefit the overall performance of poultry as well as having a positive economic impact. It should also be noted that as the birds grew, they were visually less stained, which is another important factor determining feather quality. However, this should be further investigated in future research.

  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.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.
