And Performance

This study examined the relationship between carcass composition and performance traits of local turkey fed starter diet (30.2% protein, 2950 kcal/kg ME). At 8 week of age, male and female chicks were separated and reared in individual cages until 16 weeks of age. At the end of the experiment, the birds were slaughtered and carcasses were analyzed for chemical composition to predict chemical composition (moisture, ash, protein and fat) from performance traits such as initial body weight (g) at 8wk, final live body weight (g) at 16wk, daily weight gain (g), daily feed intake (g), feed conversion ratio, daily protein intake (g), protein conversion ratio, dressing-out percentage. There were significant correlations between moisture, protein and fat; between ash, protein, fat and dressing-out percentage; between protein, fat and dressing-out percentage; between fat, moisture, ash, protein, live body weight, feed conversion ratio, protein conversion ratio and dressing-out percentage. Although the coefficient of correlation (R2) for prediction equations was not high, the moisture content equation depends on feed conversion ratio while for ash, protein and fat depends on dressing-out percentage.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P < 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P < 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P < 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

The experimental trial was carried out to study the effect of multiple phase feeding on the growth performances and the economics of broiler production for a period of six weeks. Day-old chicks (n=160) were divided into two treatment groups, each containing 80 chicks with four replicates in each treatment. The birds of the control group (A) were fed prestarter, starter and finisher diets as per nutrient requirement of commercial broiler strain used in the experiment and the multiple phase feeding was followed in group-B by changing the nutrient densities (Energy, Crude protein, lysine and methionine) of diet per week. The different performance parameters were studied such as live body weight, gain in live body weight, feed conversion ratio and feed consumption at weekly interval. Mortality was recorded daily and the economics was calculated at the end of experiment. The results of experiment showed that the body weight and weight gain of broilers of group-B was significantly higher (p less than 0.05) than that of broilers of group-A during first, second, fifth and sixth week of age and also during overall duration of the experiment. Further, the feed intake of broilers of group-B was significantly higher (p less than 0.05) than that of group-A during second, fifth and sixth weeks of age and also during the overall feed intake of broilers. The Feed Conversion Ratio of broilers of group-B was significantly better (p less than 0.05) than that of group-A during fifth week and also during the overall performance. The multiple phase feeding has not put any adverse effect on percentage mortality of broilers. However, broilers fed with the multiple phase feeding showed higher net profit per bird and also per kg of body weight as compared to the broilers of control group (A).

The objective of this study was to develop the least-cost starter’s diet and evaluated its effect on the growth performance of Sasso breeds and Indigenous ecotype of chicks under the local condition of the South Gondar Zone. The effects of substitution of different levels of commercial starters ration with homemade diet on the growth performance of Sasso and Indigenous chicks were studied in Hiruy Abaregay village of Farta district. The research area is 586km distant from the capital city of Addis Ababa, Ethiopia. A total of 510 Sasso T-44 and 90 Indigenous local ecotypes day-old chicks were randomly divided into five groups, each with 102 and 18 chicks, respectively. These were assigned into five treatments in which 100 (T1), 75 (T2), 50 (T3), 25 (T4), and 0% (T5) of commercial starter’s diet in factorial completely randomized design (CRD) with 3 replications for 60 days feeding period. The results obtained indicated that increased levels of substitution of a commercial diet with a homemade diet significantly depressed (p<0.001) mean daily feed consumption and retention of dry matter, nitrogen, and metabolizable energy. Growth rate as measured by mean daily weight gain, mean final body weight, and total feed consumption and feed cost were significantly miserable (p<0.001) in an increased homemade diet. On the contrary, there was an increase in feed conversion ratio and fiber content in high-level dilution of starter’s commercial diet with a homemade diet. However, the groups of chicks on 0, 25, and 50% commercial starters diets replaced by homemade diet were significantly higher (p<0.001) in mean daily feed intake, daily weight gain, feed conversion ratio, and final body weight attained. The results of this study indicated that up to 50% of expensive commercial starter’s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

This work investigated the effect of dietary green coffee powder (GCP) on the growth, body characteristics, antioxidant status, serum metabolites, and meat quality of 308 Ross broiler chickens. A total of 180 non-sexed seven-day old chicks were randomly distributed into three experimental groups. The untreated group received a basal diet (control), while the second and third groups were fed the original diet fortified with 1.25 and 2.5 g GCP/kg, respectively, for four weeks. Results revealed an improvement (p < 0.05) in live body weight in the group fed 2.5 g/kg GCP at five weeks of age compared to the other groups. Broiler Chicks fed the 1.25 g/kg GCP diet showed a more significant decrease in live body weight than the control group at five weeks of age. The GCP supplementation at level 2.5 g/kg GCP enhanced feed conversion ratio at 3–5 and 1–5 weeks of age. Dietary treatments did not affect (p > 0.05) carcass, dressing, and giblets percentages. Different levels of GCP significantly affected the liver, abdominal fat, intestinal length, and lymphoid organs percentages. The changes in serum blood traits and serum oxidative stress markers were not significant among the control and the treated groups. With the increment levels of GCP, results showed elevated values of meat pH, lightness (L*), and redness (a*), as well as a significant decrease in its yellowness (b*). Broilers fed 2.5 g/kg GCP diet showed a significant reduction in the total bacterial count, total yeasts and molds count, Escherichia coli, Enterococcus spp., and Salmonella spp., as well as increasing counts of lactic acid bacteria. The dietary GCP 2.5 g/kg diet supplementation could be used to decrease the pathogenic microorganisms’ populations in the broiler’s gut. The present experiment has shown that in unsexed broiler chickens, green coffee powder at level of 2.5 g/kg improved the live body weight and feed conversion ratio and decreased the pathogenic bacterial count in the gut.

A trial was conducted at the Sheep and Goat Unit of Teaching and Research Farm of the University of Ibadan, Ibadan to evaluate the effect of breeds on growth, carcass characteristics and meat yield of indigenous goats (bucks) in Nigeria. Fifteen growing bucks: five each of Sahel bucks-SB, West African Dwarf bucks (WADB) and Red Sokoto bucks(RSB) weighing 9.8±0.2, 10.0±0.4 and 9.9±0.3, respectively were fed isocaloric diet for 90 days. The experiment was laid out in a complete randomized design. Final Body Weight (FBW), Average Daily Weight Gain (ADWG) and Feed Conversion Ratio (FCR) were measured using standard procedures. Three bucks per breed were thereafter sacrificed and Dressing Percentage (DP), Meat yield, Rib eye area (REA) and Water holding capacity (WHC) were determined. The Final Body Weight of 16.1kg in Sahel bucks and 17.5kg Red Sokoto bucks were similar but significantly lower than 20.3kg of West African Dwarf bucks. Also, the Feed Conversion Ratio of 10.4 for the Sahel bucks and 9.8 of Red Sokoto bucks were significantly higher than 7.3 of West African Dwarf bucks. The Dressing Percentage was highest in West African Dwarf bucks (46.6%) and least in Sahel bucks (33.5%). West African Dwarf bucks yielded more meat lean (67.4%) and were comparatively higher than Sahel bucks (60.1%) and Red Sokoto bucks (61.5%). The Rib eye area (cm2) was also higher in West African Dwarf bucks (1.4) compared to Sahel bucks (1.1) and Red Sokoto bucks (1.1).

Phytate is an anti-nutritional factor found in grains which limits the availability of essential minerals in monogastric nutrition as they lack enzymes to break it down. Its effect on performance, nutrient retention and availability of many nutrients including the macro elements and trace minerals have been documented in many studies in different animal species with conflicting results. Thus, this study was conducted to evaluate the performance, blood metabolites and microbial population in broiler chicks fed graded levels of phytase enzyme at 0, 250, 500, 750 and 1000FTU/kg of the experimental diet in a 56-day feeding trial. One hundred and ninety-five, one-day-old Arbor acre chicks were randomly allotted into five dietary treatments in a completely randomized design and the treatment had three replicates with 13 birds each. Data were collected on performance characteristics weekly while on day 56, blood was collected at the jugular vein of two birds per replicate for haematological and serum biochemical parameters. Consequently, two birds per replicate were also sacrificed and excised for jejunum and ileum microflora assay. Result for the performance characteristics showed no significant (P>0.05) differences in final bodyweight, daily weight gain, feed intake and feed conversion ratio. Initial body weight ranged from 36.08±0.78-40.13±3.57g/bird, final body weight ranged from 2192.86±28.87- 2466.81±117.40g/bird and the Feed conversion ratio also ranged from 2.78-3.21. Also, there were no significant (P>0.05) differences observed in the haematological and serum biochemical parameters but numerical differences exist. Packed cell volume had values between 21.33-26.00% while haemoglobin also had values ranging from 7.11-8.67g/100mL. However, significant (P<0.05) differences exist in the ileum while no significant (P>0.05) differences were found in jejunum tissues. For Aspergillus flavus, 59.4±5.1cfu/mL was significantly (p<0.05) higher than 8.4±3.0cfu/mL for the ileum tissue while the jejunum tissue had values ranging from 4.2±1.80-16.8±6.00mL which were not significantly (P>0.05) different. In addition, significant (p<0.05) differences were observed for the ileum and jejunum tissue for Escherichia coli. The ileum tissue had significant values that ranged from 3.3±0.9-24.6±4.8mL while the jejunum also had significant values that ranged from 4.5±0.3-27.9±5.7mL. In conclusion, the use of microbial phytase had no influence on the performance of broilers and blood metabolite but has effect on the microflora of broiler chicken.

Twelve groups of five Israeli Friesian intact, individually fed, male calves, were slaughtered at different live weights. Commencing with 350 kg, the groups were slaughtered at intervals of 25 kg up to 625 kg live weight. Body and carcass composition data were obtained for each calf, and a feed conversion ratio was calculated.Regression coefficients of age, feed conversion ratio and carcass data on empty body weight, and also the corresponding correlations, were calculated by the equations: y = b + αx for linear and y = bxα for nonlinear regressions.Age increased at a rate very similar to that of empty body weight (α = 1·042). Increase in the amount of feed required to produce unit live weight was much slower (α = 0·045). With increasing empty body weight, dressing percentage and the percentage of kidney, channel and cod fat in the carcass increased moderately (α = 0·011 and 0·004 respectively), the percentage of the external organs decreased moderately (α = −0·010), and the percentage of bone in the carcass decreased very markedly (α = −0·277). The combined effect of these factors was to cause a marked increase in the percentage of saleable meat (α = 0·107) with increasing empty body weight.Results indicate that it is possible to increase the marketing weight of Israeli Friesian male calves considerably without any detrimental effect on carcass composition or economy of production.
