Low Protein

Dietary exogenous proteases (ENZ) can be used in poultry production to improve the growth of chickens fed low-protein (LP) diets. We hypothesized that ENZ supplemented in an LP diet would improve growth performance and physiological response in broilers for 8–35 days. To investigate this, we used a 2 × 2 factorial design with crude protein (CP, normal diet (NP) and LP) and ENZ. The LP diet contained low in 1% CP and ca. 8–12% amino acids compared to the NP diet and both NP and LP diets were added without or with (1 g/kg of diet) ENZ. We randomly allocated 720 1-week-old Ross 308 male chicks to 48 pens and experimental diets. At 21 days, dietary ENZ, but not CP, increased (p = 0.007) live body weight. Body weight gain from 8–21 days was affected (p = 0.006) by dietary ENZ, but was not affected (p = 0.210) by CP. The feed conversion ratio was affected by both CP and ENZ during the starter period (p < 0.05), by ENZ (p = 0.034) during the finisher period, and by CP (p < 0.001) during the whole period. However, the interaction between CP and ENZ did not significantly affect growth performance (p > 0.05). Dietary ENZ increased (p = 0.013) the relative weight of liver at 21 days. CP and ENZ affected (p = 0.043) total short-chain fatty acids at 21 days. However, this effect was not seen (p = 0.888) at 35 days. Dietary CP increased (p < 0.05) the serum concentrations of both uric acid and creatinine in broilers. We concluded that dietary ENZ is more beneficial to younger broilers, independent of CP levels, and that its effect was restricted to body weight and the feed conversion ratio.

Ileal Digestibility

This experiment was conducted to evaluate the effect of microencapsulated butyric (MEB) acid on growth performance, apparent ileal digestibility of protein (AID), duodenal morphology and immunity in broilers reared to 35-days. In total, 336 one-day-old Hubbard classic broiler chicks were randomly assigned to 4 dietary treatments (Control, 0.25, 0.35 and 0.45g/kg of MEB). Each treatment was replicated 3 times with 28 birds in each replicate. Feed intake, body weight gain and feed conversion ratio (FCR), parameters of growth performance and intestinal morphology, AID of protein and immunity parameters were evaluated. At the end of the experiment (35-d), 3 birds / replicate were randomly selected and slaughtered to collect blood, duodenal samples, and ileal digesta. The result indicated improved body weight gain (P<0.05), feed conversion ratio (P<0.05) and AID (P<0.05) whereas, treatments remained unresponsive with respect to feed intake (P>0.05), duodenal villous height (P>0.05) and antibody titer against Newcastle disease (ND) (P>0.05). There is an indication that MEB improves the digestion and consequently bird’s performance.

Foot Disease

Footpad dermatitis (FPD) is a major foot disease in modern poultry production, and it affects both poultry health and animal welfare. It refers to inflammation and necrotizing lesions on the plantar surface of the footpads and toes. We investigated the effects of providing a swimming pool and different floor types on growth performance and FPD score in indoor-reared White Roman geese. Forty-eight male and 48 female White Roman geese were randomly allocated to pens with or without a swimming pool and with either mud or perforated plastic floor and reared from 15 to 84 days of age. Growth performance measurements included feed intake (FI), weight gain (WG), and feed conversion ratio (FCR). FI, WG, and FCR were significantly decreased at various growth periods in geese provided with a pool. Lower WG and bodyweight for the perforated plastic floor group were found at 15–28 and 28 days of age, respectively. The geese reared on the perforated plastic floors without a pool had higher FPD scores at 70 and 84 days of age than those with other rearing conditions. A higher incidence of FPD score 1 was observed in geese raised without a pool. In conclusion, providing a pool can improve footpad health in indoor-reared White Roman geese but may not benefit growth performance.

The objective of this study was to develop the least-cost starter&rsquo;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&rsquo;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&lt;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&lt;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&rsquo;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&lt;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&rsquo;s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

An experiment was carried out to study the egg hatchability and growth performance of crossbred chickens involving Fulani ecotype (E) and Isa brown (B) chickens and their backcross using artificial insemination method of mating. The F1 progeny, the crossbred (EB), was produced by crossing E (sire) with B (dam) while the first backcross (BEB) was achieved using the B (sire) and the EB (dam). The second backcross (EBB) was carried out by mating the EB (sire) and the B (dam). A total of 35 birds were used as foundation stock (five E males, five B males and 25 B female chickens) to produce 137 EB crossbred chickens and 187 backcross chickens (98 EEB chickens and 89 BEB chickens). Weekly body weight and daily feed intake were obtained on the progenies generated from the mating for a period of 20 weeks. Other parameters like weight gain, feed conversion ratio, percentage fertility, hatchability and percentage dead shell were calculated from the data. The results revealed that the growth performance was affected by genotype. The EB chickens obtained the highest body weight across the weeks (37.6 to 1169 g) and the backcross chickens had the highest fertility (76.2%) and hatchability (83.2%). Therefore, it could be concluded that crosses between the Fulani ecotype and Isa brown chickens had the best growth performance and improved fertility while the backcross sired by the F1 had better performance when hatchability is considered.

Biochemical Indices

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

Two trials were conducted to evaluate the inclusion of glycerine, glucose, or sucrose in broiler starter diets to overcome negative effects of delayed feed access. In trial 1, 2160 newly hatched chicks (mixed sexed) were randomly assigned to two feeding programs (immediate vs. 36 h delayed feed access). Nine starter diets prepared with crude glycerine, glucose, or sucrose fed at 0%, 4%, or 8% levels were fed during the first 14 d post hatch (PH). In trial 2, 720 male and 720 female newly hatched chicks were randomly assigned to two feeding programs (immediate vs. 48 h delayed feed access). Starter diets fed during the first 14 d of feed access, consisted of a control, 8% glycerine, or 8% glucose. In both trials, a common grower and finisher diet were fed during days 14–24 and 25–35, respectively. Body weight and feed consumed were measured on 7, 14, 24, and 35 d. In trial 1, all 8% diet-fed birds were heavier compared with the control on day 35 PH (2259 vs. 2198 g, P < 0.01). Birds fed glycerine starter diets had improved feed conversion ratio (FCR) during 22–35 d (P < 0.01). In trial 2, glycerine diet resulted in heavier birds after 35 d of feed access, compared with birds fed control and glucose diets immediately after hatch (2373 vs. 2276 g, P < 0.01). Dietary inclusion of 8% glycerine can assist newly hatched broiler chicks to overcome delayed feed access induced growth suppression.

The aim of the present study was to evaluate the effects of feed particle size and flooring designs on organ traits, performance and pododermatitis in broilers. A total of 480 broilers (Ross 308) of both sexes were randomly assigned to two feeding groups (finely or coarsely ground pelleted diets; with addition of 5% to 10% intact wheat in coarsely diets) and four different housing systems (litter; litter with floor heating; partially or fully slatted floor) with three subgroups each. A coarse diet increased the final gizzard and pancreas weights (p < 0.001) while decreasing the risk of Isthmus gastrici dilatation compared to a fine diet (p < 0.001). Broilers fed a coarse diet displayed an increased final body weight (p = 0.023) and led to a favourable feed conversion ratio. Final body weight was the highest (p < 0.001) for birds housed on partially or fully slatted floor. Housing birds on litter with floor heating showed the lowest pododermatitis scoring (p < 0.001). It seems to be favourable to use coarse diets for organ development, whereas slatted floors seem to foster enlargement of the Isthmus gastrici. Increasing growth performance was possible both when using coarse diets or slatted floors.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 18 weeks old, nine castrated DYL and nine local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 0.95% total lysine for finisher and L3- basal diet with 1.45% total lysine for finisher. The growth performance and back fat thickness were determined for finishing pigs. Significantly better body weight, weight gain, feed conversion ratio (FCR) and lower back fat were observed in pigs fed L2 but did not significantly differ from those fed L3. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and feed efficiency. Between the two breeds, growth performances of DYL were superior over that of local breed. Back fat thicknesses of DYL were also thinner than that of local breed. The interactions were observed between lysine levels and different breeds regard for final body weight, cumulative gain and feed conversion ratio. It was noticeable that lysine supplementation helped to improve growth performance and reduce back fat thickness of both local breed and DYL crossed breed. The result also showed that a comparison of the two different breed revealed the improved performances in DYL crossed breed rather than that of local breed.
