The study was conducted to evaluate the feed intake, digestibility, bodyweight change and carcass characteristics of Farta lambs fed Brachiaria (now: Urochloa) hybrid Mulato II and natural pasture hays in various proportions as a basal diet supplemented with a local concentrate mixture (CM). Twenty-five yearling male Farta lambs with a mean initial body weight of 19.6±0.29 kg (mean±s.e.) were used in feeding (90 days) and digestibility (7 days) trials. The lambs were randomly allocated to the following 5 dietary treatments on the basis of stratified body weight: 100% natural pasture hay (NPH) (T1); 75% NPH+25% Urochloa hybrid Mulato II hay (MH) (T2); 50% NPH+50% MH (T3); 25% NPH+75% MH (T4); and 100% MH (T5). A local concentrate mixture [300 g dry matter (DM)/hd/d] was fed to all animals. Crude protein (CP) concentration of the basal diet increased as proportion of MH in the ration increased (P<0.05). Intake of DM and nutrients, and nutrient digestibility coefficients increased significantly (P<0.05) as proportion of MH in the roughage component of the ration increased. Final body weight, average daily bodyweight gain, feed conversion efficiency and most carcass parameters measured were significantly (P<0.05) higher as proportion of MH increased from 0 to 100% in the basal diet. Based on the biological performance of the experimental lambs, performance of sheep in the region could be enhanced significantly by incorporating MH with native pasture hay and concentrate supplement in feeding rations. Economic assessments would reveal the optimal combinations of native pasture and MH for feeding to achieve particular outcomes. Other improved grass and legume species may fill the same role and should be investigated in differing environments.

Four Levels

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.

Jack Bean

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.

Abstract This study was carried out to assess the effects of dietary supplementation of enzymatic bio-conversion of Scuterallia baicalensis (SB) extract on the growth performance, nutrient digestibility, fecal microbiota, fecal gas emission, blood hematology, and antioxidative indicators in growing pigs. A total of 200 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight of 24.52 ± 1.99 kg were used in a 42-day experiment with a completely randomized block design. Pigs were randomly divided into 4 treatment groups with 10 replicate pens per treatment and 5 animals per pen (2 barrows and 3 gilts). There were four diet conditions: 1) CON, basal diet; 2) TRT1, basal diet + 0.1% apramycin; 3) TRT2, basal diet + 0.1% SB extract; 4) TRT3, basal diet + 0.1% enzymatic bio-conversion of SB extract. The pen was taken as the experimental unit. Tukey’s multiple range test was used for evaluation of differences among the treatments. Compared with the CON group, TRT1 or TRT3 groups had higher final body weight (BW) (P = 0.074) and average daily gain (ADG) (P = 0.075), and lower feed conversion ratio (FCR) (P = 0.054). The apparent total tract digestibility (ATTD) of dry matter (DM) (P = 0.095) in TRT1 group was higher than that in CON group. Serum glutathione peroxidase (GPX) (P = 0.047) and glutathione (GSH) (P = 0.074) concentrations in TRT3 group were higher than those in CON or TRT1 groups. However, there were no significant differences in fecal microbiota, fecal gas emission, and blood hematology among all dietary groups. A positive correlation between apramycin supplementation in the diet and ADG and the ATTD of DM were observed. A positive correlation between enzymatic bio-conversion of SB extract supplementation in the diet and ADG and the concentration of GPX and GSH in serum were also observed.

Yeast Concentration

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

Caecal Microbiota

Three dietary combinations of probiotics and phytogenics administered sequentially or continuously were assessed for their effects on broiler performance, nutrient digestibility, caecal microbiota composition, volatile fatty acid (VFA) pattern and plasma total antioxidant capacity (TAC). One-day-old Cobb male broilers (n = 525) were allocated to five experimental treatments for 42 days. Each treatment had three replicates of 35 broilers each. Depending on the time-frame of sequential or continuous addition in the basal diet (BD) of the probiotics (108 CFU/kg BD) and phytogenics (125 mg/kg BD), experimental treatments were: control (no additions, Days 1–42); PE1, probiotic Days 1–14 and phytogenic Days 15–42; PE2, probiotic Days 1–28 and phytogenic Days 29–42; PE3, probiotic and phytogenic continuously (Days 1–42); and A (2.5 mg avilamycin/kg diet, Days 1–42). There was no loss of probiotic viability upon mixing with the phytogenic for up to 7 days. Overall bodyweight gain was higher (P = 0.025) in the control and PE1 than PE2 and PE3, whereas Treatment A was intermediate and not different from the rest. Overall feed intake in the control was the highest (P = 0.003). Treatments PE1, PE2 and PE3 had better (P = 0.004) overall feed conversion ratio (FCR) than the control. The FCR in PE1 and PE3 did not differ from A, which had the best FCR. Mortality did not differ among treatments. Nutrient digestibility and caecal microbiota composition did not differ among treatments. However, differences (P ≤ 0.05) in caecal VFA pattern were noted, with the control having the lowest acetate molar ratio as well as the highest sum of valeric, hexanoic and heptanoic acids. Plasma TAC in the control was lower than in PE3, PE1 and PE2 at Day 14 (P < 0.001) and PE1 (P = 0.003) at Day 42. The concept of sequential or throughout probiotic and phytogenic administration showed promising results regarding feed efficiency and plasma TAC.

Bone Mineralisation

Incremental levels of the phytase, OptiPhos® Plus, were fed to 150 weaned piglets (five treatments of 30 pigs) to determine the effect on piglet performance, nutrient digestibility and bone mineralisation. Piglets were fed a basal diet from four to six weeks and a pre-starter diet from six to ten weeks of age. The basal diets contained reduced digestible phosphorus (P) and calcium (Ca) (1.5 g/kg digestible P, and Ca 5.5 g/kg and 5.6 g/kg for weaner and pre-starter, respectively) to provide a negative control. Phytase was added at 0, 125, 250, 500 and 1000 phytase units (FTU)/kg feed. Faecal samples were collected at nine weeks of age and analysed for P, Ca and crude protein (CP) content to calculated digestibility. Metacarpal bone IV mineralisation was assessed by ash content and the weight and length of the bone. Incremental increases of phytase improved final body weight (BW) (P<0.001), average daily gain (ADG) (P<0.001) and feed conversion ratio (FCR) (P<0.01). The statistical model predicted a linear increase for daily feed intake (DFI), ADG and BW with increased phytase increments. BW at the end of the trial increased by 824 g per increase of 250 FTU/kg (P<0.001). ADG and DFI increased by 19 g/day (P<0.001) and 18 g/day (P<0.05) respectively, per increase of 250 FTU/kg. As the effect on ADG and final BW was higher at lowest doses, a quadratic effect for these parameters was observed, within the measured range of phytase levels (P=0.029 and 0.028, respectively). A reduction of 0.03 in FCR was observed for each 250 FTU/kg increase (P<0.01). For each increase in 250 FTU/kg, bone dry weight increased by 131 g (P<0.05) and bone ash concentration by 1.9% of fat free dry matter (P<0.001). The results showed that the addition of phytase to piglet diets low in P led to better utilisation of phytate-P and consequently better piglet 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.

The present study was conducted to evaluate the effect of a Commercial Herbal Growth Promoter (CHGP) with a combination of selective nine numbers of herbs on the performance of broiler chicken. A total of 120 day-old commercial broiler chicks having similar body weight from a single hatch were procured and chicks were randomly distributed into four groups viz, T0 (standard basal diet as control), T1 (basal diet + 1.0 % CHGP powder), T2 (basal diet + 2.0 % CHGP powder) and T3 (basal diet + 3.0 % CHGP powder) comprising 30 chicks in each groups. All the birds were managed under uniform managemental condition. The final body weight was significantly (P£0.01) highest in T2 (2059.83 g) followed by T3 (1956.67 g), T0 (1845.33 g) and T1 (1825.17 g). In respect of overall Feed Conversion Ratios (FCR), T2 group showed significantly (P£0.05) best FCR value of 1.69 followed by T3 (1.77), T0 (1.85) and T1 (1.87). The study revealed that there was increased body weight, improved FCR, higher BPEI, cent per cent livability and increased gross profit per broiler in birds offered 2% CHGP powder as herbal growth promoter.

The purpose of this study was to determine the effect of giving golden snail meat flour in broiler rations aged 2-5 weeks to the appearance of broiler chickens and to find out what level of golden snail meat flour can give the results of body weight gain, final body weight, feed consumption, and conversion best ration. This study used a Completely Randomized Design with 5 treatments and 3 replications for each treatment. The five treatments were rations without the content of golden snail meat flour as control and rations containing golden snail meat flour 5%, 10%, 15%, and 20%. The parameters observed were bodyweight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed by analysis of variance. If between treatments showed a real difference, then proceed with Duncan's test. The results of the study of the addition of golden snail meat flour (Pomacea canaliculata) in broiler chicken rations had a very significant effect (P<0.01) on the research variables' weight gain, final body weight, and lower FCR. Whereas the consumption of rations had a significant effect (P<0.05). In treatment R2 (10%) gave better results than other treatments (R0, R1, R3, and R4). This means that the treatment of giving golden snail meat flour in the ration apparently can increase the weight gain of broiler chickens. This is because the golden snail contains quite high protein. From the results of this study, it can be concluded that the administration of golden snail meat flour (Pomacea canaliculata) in broiler rations has a very significant effect on increasing weight gain, final weight, and decreasing FCR and significantly influencing ration consumption.

There is an extensive search for natural products that can be introduced to broiler rations to improve performance, especially during the unfavorable breeding conditions. Under heat-stress conditions, the immune response seriously deteriorates, which consequently impairs broiler production performance. Thus, the present study aimed to investigate the potentials of Citrullus colocynthis seeds (CCs) supplementation to modulate the immune response of broilers subjected to chronic heat stress. A total of 300 Cobb-500 male broiler chickens aged 21 days were randomly divided into two equal groups and reared under either thermo-neutral condition (24 ± 1 °C) or subjected to cyclic heat stress (34 ± 1 °C for 8 h). Each group was further divided into two groups (5 replicate × 15 chicks) and was fed either the basal diet or the basal diet with 0.1% CCs supplementation. The results showed that heat stress impaired the production performance by lowering the final body weight and feed intake as well as impairing feed conversion. The levels of stress markers (i.e., malondialdehyde, tumor necrosis factor-α and corticosterone) increased (p < 0.05), whereas the activity of antioxidant enzymes decreased in broilers exposed to heat stress. Further, heat stress caused direct suppression of broiler humoral and cell-mediated immune responses. The stimulating index of T and B lymphocytes proliferation, as well as the antibody titer against sheep red blood cells, were significantly (p < 0.05) reduced by heat-stress exposure. However, CCs supplementation to broilers subjected to heat stress improved (p < 0.05) the final body weight, feed intake, and feed conversion ratio (FCR), compared to the non-supplemented stressed group. The cellular and cell-mediated immune response indicators significantly enhanced (p < 0.05) with CCs supplementation. Supplementation of CCs to broilers reared under similar environmental conditions elevated the total white blood cells (TWBCs) count and the broiler stimulating index of T and B lymphocytes. It can be concluded that CC seeds can be effectively used to stimulate the immune response and improve the production performance of broilers reared under heat-stress condition.
