This work examined the effects of incorporation of exogenous enzyme preparation on growth and performance traits in broilers fed diet containing 400 g/Kg of L. angustifolius(cv. Arabella) of Europe and L. angustifolius (cv. Kalya) obtained from Australia. A maize- soy (MS) based diet served as a control diet and acted as positive, while non-protein control diet acted as a negative control (NPC) and fed ad libitum for 18 days. Growth rate, apparent digestibility of N, fat and excretion of essential minerals were assessed. In comparison to broilers fed maize-soy (MS) diet, broilers fed the L. angustifolius  of European origin (EL) diet, consumed less feed, had considerably lower body weight gain, as well as lower apparent digestibility. Addition of Rena phytase to the EL (ELPH) and L. angustifolius of Australian origin (ALPH) increased feed intake, however, the feed gain ratio was found to be decreased. . This study indicates that a diet containing high level of lupin meal is detrimental to feed intake broilers and thus affected their performance. However, when lupin meal diet was supplemented with Rena phytase, performance parameters were not different from those obtained from raw meal. The inclusion of lupin meal with or without exogenous enzyme had significant effect on the mineral content of the faeces and on mineral balance. The results suggest that lupin protrein is involved in the elevated loss of minerals associated with long-term effects of this seed as protein source in poultry. Compared to those of control, the N excretion was in the range of 14.9% (EL), 15.6% (ELPH) and 13.9% (ALPH). On the other hand, digestibility was found to be in the range of 78% (EL) and 73% (ELPH) than the corresponding control fed on (MS) diet. The fat excretion was found to be highest in (ALPH) fed diet 19.1% as compared to those of control. True fat digestibility was found to be at the lowest level n ALPH group. The present work has revealed a very remarkable property of L. angustifolius of Australian lupin, that has caused high level of fat excretion in the droppings of broilers fed this as compared to those of its European counterpart. It is highly likely that Australian lupin due to its gel forming character may have caused this kind of response in fecal lipid excretion.Bang. J. Anim. Sci. 2017. 46 (4): 266-272

Groundnut Cake

Three groundnut meals namely: groundnut cake (GNC), locally processed groundnut cake (kulikuli) and toasted groundnut seed(kernel) meal (TGSM) were incorporated in rabbit diets at two levels to generate six diets: 18% GNC, 22% GNC, 18% Kulikuli, 22% Kulikuli, 18% TGSM and 22% TGSM respectively, and 18% GNC also served as the control diet. Twenty four (24) six weeks-old growing rabbits of mixed breeds and sexes with mean initial weight of 568.75±l2.85g were randomly allocated to the six dietary treatment groups, such that each had four rabbits and each rabbit formed a replicate in a completely randomized design laid out in a 2X3 factorial arrangement and fed ad libitum, for 70 days. The main effects showed that while the treatment groups fed TGSM were significantly depressed (p<0.05). rabbits fed GNC and kulikuli were not significantly different (p>0.05) for average daily feed intake, daily body weight gain and final body weight. Feed conversion ratio (FCR) was not significantly (p >0.05) affected among treatment groups. Rabbits fed TGSM had significantly (p<0.05) better apparent digestibility coefficient (78.04%) than those on kulikuli (75.81%6) and the group on kulikuli were better than animals fed GNC (72.09%) for fat digestibility. Fibre digestibility was also significantly different (p <0.05), with rabbits fed kulikuli having the poorest fibre digestion (15.63 %). Crude protein, dry matter and NFE apparent digestibility coefficients were not significantly (p >0.05) affected. Among all the parameters measured, only fat and fibre digestibility coefficients had significant (p <0.05) interactions and NFE digestibility was significantly affected (p <0.05) by level of inclusion, with groups fed 22% digesting it better. Feed cost kg gain did not differ significantly (p >0.05) among the treatment groups. Growth was still on the rise and there was a significantly (P<0.01) strong relationship (correlation and regression) between feed intake and weight gain for all the treatment groups. was concluded that both kulikuli and TGSM are potential feed resources for rabbits, more available to house hold farmers, equally economical as GNC and better still if groundnut farmers and or processors of kulikuli raise rabbits, though TGSM had less value for growth rate compared to GNC and Kulikuli at these levels of inclusion

The intake and in vivo digestibility of Trypsacumlaxum in guinea pigs according to the graded level of spirulina was evaluated in Cameroon. 20 animals aged of 6 months with an average weight of 450 ± 50 g were randomly divided into 4 equivalent groups. Each group received T. laxum and 40g of compound feed containing 0% (TS0), 2% (TS2), 4% (TS4), and 6% (TS6) of spirulina. Feed intake was the different between the left over and the quantity served. The sample of T. laxum and those of each diet as well as feces were collected and analyzed for the apparent digestibility of each nutrient. Animals were weighed at the beginning and at the end of each period of the test to determine the body weight gain. This study showed that the average daily intake of dry matter (DM) for TS0, TS2, TS4 and TS6 was 74.39 ± 2.98, 78.66 ± 3.14, 83.89 ± 4.28 and 77.76 ± 4.40 g/head/day. The highest apparent digestibility coefficients of different nutrients were obtained with animals fed TS6 group while the lowest were observed in TS0.The apparent digestibility coefficient of dry matter (DM), organic matter (OM) and crude protein (CP) of the supplemented group were statistically higher than those of the control diet. Animals’ weight performances were statistically comparable between treatments. Thus, the combination of T. laxum with concentrated feed containing spirulina can be recommended for guinea-pigs, but the level of incorporation may not exceed 4% of its daily ration.

A study evaluated the effects of limestone sources with different solubility on the efficacy of two phytases in broilers. A 2×5 factorial arrangement was employed with two commercial limestone sources and five diet treatments; a positive control (PC) diet with 7.2 g/kg P and 9.6 g/kg Ca, and a negative control diet containing reductions of 1.87 g/kg available P, 1.99 g/kg Ca and 0.4 g/kg Na, supplemented with either Buttiauxella phytase (PhyB) or Escherichia coli phytase (PhyE) at 500 or 1000 FTU/kg diet. The two limestone sources were feed-grade commercial products with different particle sizes and solubility (fast-soluble (FS) 100%; slow-soluble (SS) 26% soluble after 30 minutes at pH 3) containing similar levels of Ca. Diets were fed to one-day-old Ross 308 males (n=2,400) with 30 birds/pen and eight pens/treatment in two phases (starter 0-10 d and grower 10-21 d). On d 21, ileal digesta was collected from 12 birds/pen to determine apparent ileal digestibility (AID) of P and Ca, and myo-inositol hexakisphosphate (IP6) disappearance, and tibias from four birds/pen for ash determination. The SS limestone improved body weight gain (BWG), feed intake (FI) and FCR vs FS limestone in starter/grower phases (P<0.05), and improved AID of P (P<0.05) and IP6 disappearance (P<0.05) at d 21. There was an interaction between limestone and phytase on BWG, FI and FCR in the grower phase (P≤0.05) whereby FS (vs SS) limestone reduced BWG at either dose of PhyE, but only at 500 FTU/kg of PhyB. At an equivalent dose, PhyB had higher BWG and feed intake than PhyE (P<0.05). At 1000 FTU/kg, performance was equivalent (BWG and FI) or superior (FCR) to the PC, PhyB produced greater tibia ash, AID of P and IP6 disappearance (P<0.05). The findings showed that the effects of limestone particle size on phytase efficacy varied with phytase source and dose.

Abstract Background Dietary 2-hydroxy-4-methylselenobutanoic acid (HMSeBA) supplementation can exert antioxidant effects in poultry, pigs and weaned pigs. However, it is unknown whether HMSeBA could improve the development of follicle by anti-oxidize effects in gilt. This study was conducted to evaluate the effects of dietary HMSeBA supplementation on the follicle development in gilt. A total of 36 gilts were randomly fed the control diet (CON, negative control), Na2SeO3 diet containing 0.3 mg Se/kg (positive control) or the HMSeBA diet containing 0.3 mg Se/kg from weaning to the 19th day after the second estrus. In another study, the effect of HMSeBA on the cells viability, proliferation, release of 17βestradiol (E2 ) and antioxidant capacity were investigated in the mouse ovarian granulosa cells in vitro. Results Results showed that HMSeBA group increased the average daily body weight gain (ADG) and decreased the ratio of feed: gain during day 120 to 176 in gilts ( P < 0.05). The selenium (HMSeBA and Na 2 SeO 3 ) increased the weight of uterine at the third estrus. There was no effect of HMSeBA on the number of large follicles (diameter >5mm), but HMSeBA decreased the gene expression of growth differentiation factor-9 ( GDF-9 ) and bone morphogenetic protein-15 ( BMP-15 ) in cumulus-oocyte complexes (COCs). HMSeBA group increased the total selenium content in serum ( P < 0.05) and liver ( P < 0.01) and tended to increase the total selenium content in ovary ( P = 0.08). HMSeBA group decreased the malondialdehyde (MDA) concentration in the serum, liver and ovary ( P < 0.05), increased the total antioxidant capacity (T-AOC) in the liver, thioredoxin reductase (TrxR) in the ovary ( P < 0.05) and increased the activity of GPx in the serum, liver and ovary ( P < 0.05). Na 2 SeO 3 supplementation decreased MDA and increased the T-AOC in liver, increased the T-SOD and TrxR in the ovary compared with control. At the transcription level, HMSeBA group increased the glutathione peroxidase 2 ( GPx2 ) and TrxR1 ( P < 0.05) expression in the liver, and increased the GPx1 expression ( P < 0.05) in the ovary of gilts compared with Na2SeO3 treatment. Besides, HMSeBA group increased the expressions of superoxide dismutase 1 ( SOD1 ) and Thioredoxin l ( Trx1 ) in the liver. In vitro experiment, HMSeBA improved granulosa cells’ proliferation and E2 secretion ( P < 0.05). HMSeBA and Na 2 SeO 3 both increased the T-AOC and decreased MDA in granulosa cells in vitro. Meanwhile, HMSeBA increased T-SOD, GPx, glutathione reductase (GR) and TrxR activity in granulosa cells in vitro. In addition, HMSeBA up-regulated SOD2 and GPx1 gene expression in the granulosa cells in vitro.Conclusion These results demonstrate directly, HMSeBA was more conducive to absorption and storage of selenium in the liver and ovary in gilt, and beneficial to exert the effect of HMSeBA on the antioxidant function in the liver and ovary of gilt. Moreover, HMSeBA has stronger antioxidant capacity in granular cells in vitro , which is more conducive to promoting follicle development. Therefore, the new type of organic selenium, HMSeBA, could be potentially useful for the control of reproductive processes in gilt.

The effect of two classes of exogenous enzymes on the egg fertility traits, egg production efficiency and oviduct micro-structure of laying hens was evaluated. Forty-five laying hens (30-weeks old, 1.32-1.40 kg) were randomly allotted into three dietary treatments with fifteen birds per treatment (five birds each in three replicates per treatment) in a completely randomized design. Diet one served as the control diet. Diet two (FS diet) contained a nutrient-targeted exogenous enzyme preparation (Fullzyme®) at 200 g/ton, while diet three (DS diet) contained a mycotoxin-targeted exogenous enzyme preparation (Detoxizyme®) at 500 g/ton. Data on fertility traits (egg volume, length and breadth, weight, yolk diameter, albumen height, air cell, shell thickness, Haugh’s unit, and egg-lay), and egg production (feed intake, egg lay, egg lay efficiency, and feed cost per egg laid) were collected for 42 days. At the end of the experiment, three randomly selected birds per group were euthanized, and their oviducts were harvested and processed for histopathology. Hens fed enzyme supplemented diets had significantly (p < 0.05) better egg fertility traits. Feed intake in the control group did not vary (p > 0.05)from feed intake in the DS or FS group. However, feed cost per egg laid and egg-lay efficiency was higher in the control diet group than in the FS group or DS diet group. No pathologies were observed in the oviduct of birds fed enzymes supplemented or control diet. Exogenous enzymes in diet improved egg fertility traits and production without altering the oviduct micro-structure of Layer hens.

Functional additives, such as autolyzed yeasts, have been used to achieve greater production efficiency and animal health. These compounds are also alternatives to the use of performance-enhancing antimicrobials. The objective was to evaluate the productive performance, ingestive behavior, apparent digestibility of feed DM and the carcass characteristics of beef steers finished in feedlot receiving autolyzed yeasts in the diet. The experimental design was randomized blocks, consisting of three treatments and six repetitions, where each repetition was represented by a stall with two animals. 36 bulls, ½ Angus × ½ Nelore blood, from the same herd, with an average age of 11 months and an average body weight of ± 330 kg were used.The treatments were as follows: CON - yeast-free diet; Y4 - yeast diet (4 g animal day-1) and Y7 - yeast diet (7 g animal day-1). The product used is a functional ingredient containing the yeast Saccharomyces cerevisiae. The inclusion of autolyzed yeasts resulted in greater daily body weight gain and better feed conversion in the initial feedlot phase. The apparent digestibility of DM of diets containing autolyzed yeast was superior to the control diet, and its use did not interfere with the animal ingestive behavior. Supplementation with autolyzed yeasts at the inclusion level of 4 g day-1 promoted better results in the finishing of feedlot steers, and that the supplemented groups (4 g animal day-1 and 7 g animal day-1) achieved the same degree of carcass finishing, higher than the control group.

A total of seventy-two weaner rabbits of eight weeks of age were used to assess the effects of replacing groundnut cake (GNC) with blood vegetable waste meal (BVWM) in the diets of rabbits. The BVWM was fed to replace dietary GNC at 0, 15, 30, and 45%, with GNC being 15% in the control diet. The four experimental diets were fed ad libitum for a period of eight weeks. BVWM was analyzed to contain a crude protein value of 62.35%. There were comparable feed intake values by rabbits on all the diets although the rabbits in the higher replacement levels of BVWM tended to have consumed more of the feed. There were significant increases (P<0.05) in body weight gain by rabbits as the BVWM level increased in the diet. Similarly, the feed to gain ratio improved and nitrogen digestibility increased (P<0.05) with higher levels of BVWM in the diet. This study shows that rabbits can tolerate the 45% BVWM replacement of groundnut cake effectively.

SummaryThe following trial was conducted to investigate the effects of Se source (inorganic sodium selenite (SS) versus organic use Sel-Plex® (SP; Alltech Inc, Nicholasville, KY, USA)) on the performance, feathering and meat quality of 900, one-day-old male broilers over a 42 day growing period. Pens (n = 20) were randomly assigned to either: Diet A (no Se; negative control), Diet B as for diet A plus 0.3 mg/kg SS (positive control), Diet C as for diet A plus 0.2 mg/kg SP, Diet D as for diet A plus 0.3 mg/kg SP and Diet E as for diet A plus 0.4 mg/kg SP. From day 1 to 28, significant (P < 0.05) treatment effects were seen for feed intake and FCR, with values for the negative control being higher than for the diets containing Se. The best FCR was recorded for the diet containing 0.4 mg/kg SP. Breast meat yield for birds fed the negative control were lower than those fed selenite or SP supplemented diets (P < 0.05). Feather measurements on d 14, 28 and 42 of age showed that, although scores became poorer with age (4.9 at 14 d, 4.6 at 28 d and 3.6 at 42 d), they were unaffected (P > 0.05) by dietary Se inclusion. Numeric trends in favour of SP were seen in cooking losses in meat chilled for 24 hours and seven days. Cooking losses in meat frozen for seven days were significantly influenced by Se inclusion, whereby values for birds fed 0.3 and 0.4 mg/kg SP were significantly lower than values for birds fed inorganic selenite (P < 0.05). Tissue Se concentrations were highest for the SP diets. Meat oxidation from the birds fed SP was lower than for the birds fed no Se or SS. The results demonstrated that SP may be more advantageous in improving certain variables of performance and meat quality compared to inorganic sources of Se.

Impact of exogenous carbohydrases and phytase on growth performance and nutrient digestibility in broilers. Can. J. Anim. Sci. 93: 243–249. The effect of supplementing corn–soybean-based diets with Rovabio®Max AP, an exogenous enzyme mix with carbohydrase (xylanase and β-glucanase) and phytase activities to broiler chickens was evaluated. Male Ross 708 broilers were assigned to four diets: positive control (PC), negative control (NC), deficient in metabolizable energy (ME), crude protein (CP), calcium (Ca) and non-phytate phosphorus (nPP), relative to the PC, by 100 kcal kg−1, 5 g kg−1, 1.1 g kg−1and 1.6 g kg−1, respectively, in the starter and grower diets; and NC+Rovabio®at 0.05 or 0.075 g kg−1diet. Starter diets were fed from day 0 to day 21 and grower diets from day 22 to day 42. Body weight (BW) and body weight gain on days 22 and 42 were increased (P<0.05) by enzyme supplementation. Enzyme addition increased (P<0.05) feed intake from day 22 to day 42 and overall (day 0 to day 42). Gain to feed ratio (G:F) was significantly increased (P<0.05) with enzyme supplementation during both starter and grower phases. Enzyme addition increased (P<0.05) serum phosphorus (P) concentration on day 21. On day 42 enzyme supplementation increased (P<0.05) the apparent ileal digestibility of P, dry matter (DM), energy, and N. Addition of a combination of carbohydrases (xylanase and β-glucanase) and phytase to corn–soybean-based diets deficient in ME, CP, Ca and P resulted in a significant increase in growth performance and utilization of P, DM, energy and N in broiler chickens.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.
