“…However, the high-oleic peanut (HOPN) treatment group had a significantly higher AMEn than the other two treatments 2 . In parallel, Redhead et al 3 reported significantly higher AMEn levels for their high oleic peanut dietary treatment group as compared to the conventional control in a layer feeding trial. The ileal protein digestion was also greater in hens fed the high oleic peanut-containing diets compared to the conventional controls.…”

“…Hence it is important to understand that these feed ingredients can replace corn fully or partially, without having negative effects on production performance 1 . Some research has examined how feeding high-oleic peanuts affects production performance of both broilers and laying hens 2,3 , while others have evaluated how feeding sweet potato roots, vines and peels would affect poultry performance 3 . Most feeding trials have only examined the performance and production aspects of these alternative feed ingredients but it is also important to understand the nutrient digestibility of these ingredients when fed.…”

Objective: The studyʼs goal was to compare, apparent metabolizable energy corrected for nitrogen, apparent nitrogen retention, apparent fat digestibility and apparent protein digestibility (APD). Materials and Methods: Four isocaloric and isonitrogenous diets were fed to 80 Shaver hens for six weeks. Diets had a 2% inclusion of Celite indigestible marker. The four diets were (1) Conventional corn-soybean control, (2) 8% inclusion of high oleic peanut, (3) 4% inclusion of sweet potato by-product and (4) 4% sweet potato by-product +4% high-oleic peanut inclusion. Results: Control and birds fed a high-oleic peanut containing diet had greater apparent metabolizable energy values than other treatments, while diets containing sweet potatoes and high oleic peanuts had the least (p<0.0001). Apparent nitrogen retention for hens fed a diet containing sweet potatoes was significantly lower (p<0.0001) than other treatments. The diet containing both sweet potatoes and high oleic peanuts had highest apparent fat digestibility (p<0.0001) than other treatments. Control had the lowest apparent fat digestibility with the high oleic containing diet being slightly higher. The apparent protein digestibility of the diet containing sweet potatoes was higher than all treatments (p<0.0001). Control and the birds fed a diet containing high oleic peanuts were lower than the birds fed a diet with sweet potatoes included. Conclusion: This study implicated that diets containing sweet potato are a reasonable alternative feed ingredient for layers and sustainable utilization of a considerable agricultural waste by-product.

“…Studies have shown that feeding peanut meal prepared from normal-oleic peanuts as a good alternative that does not hinder performance [1][2][3] . Some research has shown that feeding a diet containing high-oleic peanuts could also be a viable alternative in both laying hens as well as broilers [4][5][6][7] . However, there is very little research on how digestible a diet including peanuts is for poultry and specifically laying hens.…”

Objective: The present is study was conducted to determine the effect of feeding whole-in-shell peanuts or high-oleic peanuts to laying hens on ileal nutrient digestibility. Materials and Methods: A total of 16 birds per treatment were utilized for 6 weeks with ileal and fecal content being collected at trial termination. Apparent metabolizable energy corrected for nitrogen, apparent nitrogen retention, and apparent protein and fat digestibility were examined. Results: There were no significant differences in egg production, feed intake, or feed conversion between treatments. Apparent metabolizable energy and the apparent nitrogen retention was significantly lower in diets containing whole in shell peanuts than the other two treatment diets. Apparent fat digestibility was significantly higher for the treatment with whole in shell peanuts than the other diets, and the high oleic peanut containing diet was significantly higher than the control. Apparent protein digestibility was greater for control diet than the other treatments and the diet containing whole in shell peanuts had significantly lower protein digestibility compared to the diet with high oleic peanuts in it. With the apparent metabolizable energy and the apparent nitrogen retention for high oleic peanut containing diet being statistically the same as the control diet results could indicate that these hens can use the energy and nitrogen for their production. Conclusion: Results indicate that 8% inclusion of high oleic peanuts in diet could be beneficial however feeding whole in shell peanuts may have poorer digestibility results, but not reduce production performance. Both high oleic and whole in shell peanuts could be good alternative feed ingredients.

“…Hence, whole unblanched (skin intact) peanuts may serve as a nutrient-rich value-added alternative feed ingredient for animal food production while reducing the production of agricultural waste by-products from the peanut industry. Thus, numerous studies have been conducted to explore the effective utilization of peanuts and/or peanut by-products within the animal feed as value-added feed components [3][4][5][6][7][8][9][10] and to enhance agricultural sustainability.…”

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.
