This study was conducted to investigate the growth performance, carcass traits, blood parameters, rumen enzymes, and fattening earnings of beef cattle when substituting corn stalk silage with corn silage or corn grain in finishing rations. Forty-five Bohai Black steers were selected and fattened in a three-phase (4 weeks–4 weeks–16 weeks) way with one of three diets based on corn silage (CS), corn stalk silage (SS) without/with equivalent corn grain supplement (SSC), respectively. During the 24-week trial, individual feed intake and body weight were recorded every four weeks. By the end, blood and rumen fluid were sampled, and all the cattle were slaughtered to evaluate carcass performance. There were no significant differences found in the body weight gain, daily feed intake or feed efficiency among different dietary treatments over the whole finishing period except that the cattle fed CS achieved higher weight gain and feed efficiency in Phase 2 than those fed SS or SSC along with a lower feed intake than that of cattle fed SSC. No significant effect was found on the hot carcass weight, chilled carcass weight, dressing percentage, aging loss, loin eye area, and the weights of chuckeye, ribeye, striploin, and tenderloin. The cattle fed CS showed lower blood concentrations of ALT and glucose along with a higher ratio of AST and ALT than those fed SS. The cattle fed SSC also presented a higher activity of avicelase in the rumen fluid and their fattening earnings were approximately $27.50 less than those of the cattle fed CS or SS. These results suggest that substituting corn stalk silage with corn silage or corn grain could not improve animal performance and it is more economical to substitute corn stalk silage with corn silage rather than supplement equivalent corn grain in a high-concentrate finishing ration.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

Abstract This study was conducted to examine the growth performance and expression patterns of growth hormone gene and insulin-like growth factor in metabolic tissues of pigs fed different unconventional feed sources. A total of 45 growing pigs were randomly assigned to 5 dietary treatments at 9 animals per treatment and 3 animals per replicate. Treatment one (T1) comprise of whole maize (WM) which served as the control, T2: brewers dried grain (BDG), T3: cassava peel meal (CPM), T4: plantain peel meal (PPM) and T5: corn husk meal (CHM) at 35% inclusion in the diet. Data collected and analyzed includes; initial body weight (IBW), final body weight (FBW), average daily feed intake (ADFI), average daily weight gain (ADG), feed conversion ratio (FCR) and feed efficiency (FE). At the end of the feeding trial, three animals per treatment (one animal per replicate) were slaughtered; the duodenum and liver were collected and stored using RNALater prior to RNA extraction. Real-time qPCR was performed in 40cycles using the PowerUp SYBR Green reagent and analysed using the Delta-Delta Ct method. All data were subjected to analysis of variance in a completely randomized design. The results showed that the treatment diets had effect on growth performance with significant differences (P &lt; 0.05) observed for average final weight, average total weight gain, average daily feed intake, feed conversion ratio and feed efficiency while the initial weight were not significantly different (P &gt; 0.05). IGF-2 was differentially expressed in the liver and duodenum across treatments while significant differences were not observed in the expression pattern of the growth hormone gene in both tissues. This study showed promise for the use of unconventional feeding stuffs in pig feeding and reveals that genes influencing performance characters are differentially expressed in relation to the source of unconventional feeds used in compounding pig diet.

Three experiments were conducted to determine the effects of monensin on feed intake, rate of gain and feed efficiency of a total of 198 Holstein steers. In experiment I, 72 steers were fed ground ear corn and corn silage diets containing 0 (treatment 1), 22 (treatment 2) and 33 (treatment 3) g/tonne DM monensin for 112 days. Treatments 2 and 3 received 11 g/tonne DM monensin for the first 28 days. Daily gains were not significantly different (P > 0.05) throughout the trial and intake was slightly reduced (P > 0.05) with monensin addition. Feed efficiency in treatments 2 and 3 were improved 5.5 and 8.8% respectively, but only treatment 3 was significantly (P < 0.05) better than treatment 1. Rumen fluid from steers fed treatment 3 contained a higher proportion (P < 0.05) of propionic acid and a lower (P < 0.05) A:P ratio than did rumen fluid from treatment 1. Levels of acetic and butyric acid were reduced (P > 0.05) by monensin inclusion. In experiment II, 46 steers were fed hay crop silage and shelled corn diets containing 0 (treatment 1) and 33 g/tonne DM (treatment 2) monensin for 112 days. Gains were slightly (P > 0.05) higher and intake slightly (P > 0.05) lower on treatment 2. Monensin improved (P > 0.05) feed efficiency by 8.5%. In experiment III, 40 purchased and 40 station-reared steers were assigned by origin, in pairs, to 40 Calan electronic headgates. A 23 factorial experimental design was used to evaluate the effect of diet with or without monensin used separately and in combination with progesterone-estradiol implants. Steers were fed a high moisture ear corn and corn silage diet for 84 days. No 3-factor interactions (P > 0.05) were detected. Implant treatments gained significantly (P < 0.05) faster than either control or monensin alone. Intake was significantly (P < 0.05) lower in treatments fed monensin. Feed efficiency was improved (P < 0.05) 16% with both monensin and implant, 10% (P < 0.05) with monensin alone, and 6% (P > 0.05) with implant alone over control.

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 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 seed conversion ratio were significant (P<0.05). Birds fed cassablood based 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 contentswhichdiffered (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.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

The use of insect meals in place of soybean meal in diets is critical for sustainable intensification of poultry production, but the utility of this alternative dietary protein source is unknown for the Jumbo quail. Therefore, this study investigated the effect of partial substitution of soybean with black soldier fly larvae (BSFL) meal on feed intake, physiological, and meat quality parameters of Jumbo quails. Three hundred and fifteen mixed-gender quails (53.8 ± 5.19 g live-weight) were reared on five isonitrogenous and isoenergetic experimental diets formulated by replacing soybean products with BSFL meal at 0 (BSFL0), 25 (BSFL25), 50 (BSFL50), 75 (BSFL75), and 100 (BSFL100) g/kg. Feed intake, body weight gain, gain-to-feed ratio (G:F), blood parameters, and carcass and meat quality traits were determined. Quadratic trends were observed for overall feed intake (y = 605 (±17.56) + 2.1 (±0.82)x − 0.02 (±0.008)x2; R2 = 0.20; p = 0.023) and overall body weight gain (y = 155 (±4.70) + 0.57 (±0.22)x − 0.005 (±0.002)x2; R2 = 0.22; p = 0.026) in response to BSFL levels. However, there were neither linear nor quadratic trends for meat quality and blood parameters, except for albumin-to-globulin ratio. Only gizzard size linearly increased (y = 0.05 (±0.004)x + 2.3 (±0.09); R2 = 0.18; p = 0.04) with BSFL levels. We concluded that BSFL meal could replace soybean products in Jumbo quail diets at 54 g/kg without compromising weight gain and meat quality.

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

A total of 270 native chickens of two months of age were reared up to their six months of age under three densities D1, D2 and D3 (0.186, 0.279 and 0.372 m2/bird) and three flock sizes F1, F2 and F3 (20, 30 and 40 birds/flock) to find out the effect of density (D) and flock size (F) on the growth performance of native chicken under intensive system of management. Body weight gain and feed intake were higher (5.62 & 5.39 and 50.17 & 50.42) and feed conversion ratio and mortality were the lower (9.48 & 10.02) in D2 unit and (12.01 & 13.05) in F2 unit. On the other hand, body  weight gain was the lowest (4.81) in D3 unit. Feed intake was the lowest (49.25) in D1 unit with the highest (11.70) FCR value. Body weight gain was found to be the lowest (4.81) in F3 unit but its FCR and mortality rate were the  highest (11.25 and 17.71). Feed intake was observed to be the lowest (49.17) in the F1 unit. Considering the growth  performance of native chickens under different densities and flock sizes, it could be concluded that flock size F2 (30 birds/flock) performed better at the density level D2 (0.279 m2/bird) than other densities and other flock sizes.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12040   J.
