High Oleic Peanuts

Abstract Locally grown feed ingredients of high energy and protein content, such as peanuts, maybe economically feasible alternatives to corn and soybean meal in broiler diets. Even though normal-oleic peanuts have been demonstrated to be a viable feed ingredient for poultry, few studies to date have examined the use of high-oleic peanuts (HO PN) as an alternative feed ingredient for broiler chickens. Thus, we aimed to determine the effect of feeding HO PN on broiler performance, nutrient digestibility, and intestinal morphology. Three isocaloric, isonitrogenous experimental diets were formulated with 1) dietary inclusion of ~10% coarse-ground whole HO PN; 2) a corn-soybean meal control diet with 5.5% added poultry fat; and 3) a control diet supplemented with 5.5% oleic fatty acid oil. Three-hundred Ross 708 broilers were randomly placed in 10 replicate pens per treatment with 10 chicks per pen and raised until 42 d. Body weights (BW) and feed intake were determined weekly, and feed conversion ratio (FCR) was calculated. Jejunum samples were collected at 42 d for histomorphometric analysis. Analysis of variance was performed on all variables using a general linear mixed model in JMP Pro14. Broilers in the HO PN group had lower (P < 0.05) BW and higher FCR than other treatment groups at weeks 2 and 6. There were no significant differences in the jejunum villi surface area between the treatment groups. However, broilers fed the HO PN diet had greater (P = 0.019) apparent metabolizable energy relative to the other treatment groups, suggesting improved nutrient uptake of dietary fats and/or carbohydrates in the HO PN treatment group. However, additional studies are warranted to further define the nutritional value of HO PN as an alternative poultry feed ingredient.

Abstract We aimed to determine the effects of feeding a high-oleic peanut (HOPN) diet to egg-producing laying hens on egg quality, digestibility, and feed conversion. Three isonitrogenous and isocaloric dietary treatments were formulated with 1) Control diet (CON)—a corn-soybean meal conventional diet with 7.8 % added poultry fat, 2) HOPN diet—dietary inclusion of ~20% coarse-ground whole HOPN, and 3) oleic acid (CON-OA) diet—a control diet supplemented with 2.6% oleic fatty acid oil. Ninety-nine 57-wk-old brown Leghorn laying hens were randomly assigned to 33 animals per treatment. Animals were housed individually for 8 wk. Body and feed weights were recorded weekly and feed conversation ratio was calculated. Bi-weekly, shell eggs were analyzed for quality (yolk color, albumen height, and Haugh unit [HU]). Jejunum samples were collected at week 8 for histomorphometric analysis. Analysis of variance was performed on all variables using a general linear mixed model. Laying hens fed the CON-OA diet produced greater number of eggs relative to those fed the HOPN and control diets (P < 0.05). The roche yolk color value was higher (P < 0.001) in eggs from hens fed the HOPN diet. There were no differences in laying hen performance, eggshell color, eggshell strength, eggshell elasticity and egg albumen height, or egg HU, ileal fat digestibility, or villi surface among treatment groups. However, the apparent metabolizable energy (P < 0.01) and ileal protein digestibility (P = 0.02) were greater in laying hens fed the HOPN diet relative to the CON diet. This study suggests that whole unblanched high-oleic peanuts may be an acceptable alternative feed ingredient for laying hens.

The abundance of peanut and poultry production within the state of North Carolina and the US Southeast, led us to conduct a layer feeding trial to determine the utilization of whole-in-shell high-oleic peanuts (WPN) and/or unblanched high-oleic peanuts (HOPN) as an alternative feed ingredient for poultry. To meet this objective, we randomly assigned 576 shaver hens to 4 dietary treatments (4 rep/trt). The dietary treatments consisted of a conventional control diet (C1), a diet containing 4% WPN, an 8% HOPN diet, and a control diet containing soy protein isolate (C2). Feed and water were provided for 6 weeks ad libitum. Pen body weights (BW) were recorded at week 0 and week 6 (wk6), and feed weights were recorded bi-weekly. Shell eggs were collected daily and enumerated. Bi-weekly 120 eggs/treatment were collected for quality assessment and egg weight (EW), while 16 eggs/treatment were collected for chemical analysis. There were no significant differences in BW or EW at week 6. Hens fed the C2 produced more total dozen eggs relative to C1 hens over the feeding trial (p < 0.05). Hens fed the C1 diet consumed less total feed relative to the other treatments with the best feed conversion ratio (p < 0.05). Most eggs produced from each treatment were USDA grade A, large eggs. There were no differences in egg quality, with the exception of yolk color, with significantly higher yolk color scores in eggs produced from the C1 and C2 treatments relative to the other treatments (p < 0.05). Eggs produced from the HOPN treatment had significantly reduced stearic and linoleic fatty acid levels relative to the other treatments (p < 0.05). Eggs produced from hens fed the WPN diet had significantly greater β-carotene content relative to eggs from the other treatment groups (p < 0.05). In summary, this study suggests that WPN and/or HOPN may be a suitable alternative layer feed ingredient and a dietary means to enrich the eggs produced while not adversely affecting hen performance.

This study aimed to determine nutrient metabolizability coefficients and apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values of moringa leaf meal and bocaiuva pulp for slow-growing broilers. Three hundred and fifty 1-day-old chicks of the Red Naked Neck line were allocated to five treatments in a completely randomized design with seven replicates of 10 birds. Treatments consisted of a control diet and four test diets. The proportion of ingredients evaluated in the test diets was 20% moringa leaf meal and bocaiuva pulp and 40% corn and soybean meal. The total excreta collection method was applied with 1% ferric oxide included in the diets as a marker of start and end of collection, in the starter, grower and finisher phases. The metabolizability coefficients of dry matter, crude protein and ether extract and the AME and AMEn values of moringa leaf meal, bocaiuva pulp, corn and soybean meal were determined. Data were subjected to analysis of variance and means were compared by Tukey’s test at the 5% probability level. The protein from moringa leaf meal and the fat from bocaiuva pulp are highly metabolizable by birds at different ages. The AME and AMEn values of moringa leaf meal ranged from 2557 to 2868 Kcal/kg and 2205 to 2479 Kcal/kg, respectively. In bocaiuva pulp, AME and AMen ranged between 2680 and 3119 Kcal/kg and 2483 and 2490 Kcal/kg, respectively. Therefore, the alternative ingredients can be used in the formulation of diets for slow-growing broilers to partially replace corn and soybean meal.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

Diet Type

A 21-day experiment was conducted to study the effect of reference diet type and assay method on apparent metabolizable energy (AME) and nitrogen-corrected (AMEn) of soybean meal (SBM) and canola meal (CM). Broilers (n = 240) were allocated to 10 treatments with eight replicates/treatment and three birds/replicate. Treatments included corn-SBM or corn-CM reference diets (RD). To each RD, 300 or 450 g/kg of SBM or CM were added to make a total of eight test diets. For the difference method, AME of SBM and CM substituted at 300 g/kg in corn-CM RD gave greater AME values compared to inclusion in the corn-SBM RD. The AMEn of SBM increased with increase in inclusion level in the corn-CM RD but AMEn of CM decreased with increased inclusion level of CM in the corn-SBM RD. For the regression method, AME and AMEn of the test feedstuffs were greater with corn-CM RD compared with corn-SBM RD. The AME of SBM was not affected by assay method, whereas AME of CM was lower when determined using the regression method. In conclusion, both the reference diet type and assay method influenced assayed AME and AMEn value of test protein feedstuffs and should be considered in cross-studies comparisons.

The Difference

Two experiments were conducted to evaluate adaptation length (AL) and composition of reference diets on nitrogen (N)-corrected apparent metabolizable energy (AMEn) in 22-d-old broilers. Birds were allocated to nine treatments (n = 6) consisting of wheat – soybean meal (SBM) (reference diet), corn–wheat–SBM, and wheat middlings (WM)–wheat–SBM (exp. 1), or oats–SBM (reference diet), corn–oats–SBM, and WM–oats–SBM (exp. 2) in conjunction with three AL (12, 8, and 4 d) in a factorial arrangement of treatments (3 × 3). Dry matter (DM), N, energy (En) utilization, and AMEn of corn and WM were determined using the difference method. In exp. 1, birds on the WM–wheat–SBM-based diet had the lowest (P < 0.05) DM, N, and En utilization, as well as AMEn compared with the other two diets. Additionally, AMEn for corn was higher (P < 0.05) compared with that of WM. In exp. 2, N utilization in birds on the corn–oats–SBM-based diet was lower (P < 0.05) compared with birds on the oats–SBM-based diet; however, AMEn of corn and WM was not different. In both experiments, AL was not significantly different. Based on these results, the composition of the reference diet could influence AMEn values of corn and WM in 22-d-old broilers.

Apparent Metabolizable Energy

True metabolizable energy (TME) of soybean meal and rapeseed products was determined in two laboratories by feeding the ingredients singly or mixed with a basal diet. Apparent metabolizable energy (AME) was also determined on the same samples and the values compared with TME. TME results between the two laboratories agreed well for the soybean meal and rapeseed meals obtained either by feeding the ingredients alone or with the assay diet, but with whole rapeseeds there was wide disagreement. This was due to poor and variable utilization of the whole seeds by birds in the two laboratories. AME values for the whole rapeseeds were considerably lower than expected, but the values for the rapeseed meals were as anticipated. Grinding significantly (P < 0.01) increased the AME of Tower and Candle rapeseed and the TME of Candle rapeseed. Tower and Candle rapeseed meals did not differ significantly in TME or AME; nor were there differences in the ground seed of the two cultivars.

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

ABSTRACT Two experiments were carried out to determine the energy values and the true ileal digestibility of amino acids of nine toasted full-fat soybeans (FFSB), without or with the addition of monocomponent protease. In the first experiment, to determine the energy values, the method of excreta collection was used with 1120 broiler chicks at 14 days old, distributed in randomized blocks in a 10x2 factorial arrangement with nine full-fat soybeans (30% included) plus a control diet (70%) without or with the addition of protease, totaling 20 treatments with 8 replicates and 7 birds per cage. In the second experiment, 1120 broiler chickens from 24 to 28 days of age were distributed in randomized blocks in a 10x2 factor arrangement, with nine full-fat soybeans (40% included) + a protein free diet (60%), without or with the addition of protease, totaling 20 treatments with 8 replicates and 7 birds per cage. Ileal digesta collection was used to determine the true digestibility coefficients and the digestible amino acid content of full-fat soybean. The average values of nitrogen-corrected apparent metabolizable energy (AMEn) and their respective metabolization coefficients (CAMEn) were 3207 kcal/kg and 62.57%, respectively. The average values of digestibility coefficients of crude protein and essential and nonessential amino acids were 86.79, 87.90 and 84.34%, respectively. The inclusion of protease improved (P<0.05) all evaluated parameters. Therefore, its use is recommended in diets containing full-fat soybeans for broiler chickens.
