“…The reduction in EW is consistent with earlier work of Alkanji and Ologhobo (2007) who found that elevated phytate contents in raw seed legumes contribute to the reduction in EW. The tendency of EW to increase with age in the present study agrees with Aziza et al (2013) and Hurnik et al (1997) who reported that egg size increases with age in layers but stabilizes within 4 to 6 weeks of laying. Leeson and Summers (1997) and Munisi et al (2016) observed that EW is lowest at the beginning of the production cycle but increases as age and body weight increases throughout the laying period.…”

A 90 days study was conducted to compare the effects of feeding Tswana hens reared under intensive system and fed diets formulated from Imbrasia belina (Westwood), Vigna subterranea (L) Verde and Tylosema esculentum (Burchell) Schreiber as sources of protein on egg quality. Four isonitrogenous and isocaloric diets were formulated by totally replacing soybean meal (SBM) with I. belina, V. subterranea and T. esculentum as protein sources while commercial layer diet was used as control diet. Twelve eggs from each pen were collected at 28, 33 and 38 weeks of age for egg quality analysis in a completely randomized design. Egg weight (EW), shell weight (SW), shell thickness (ST), shell index (SI), shell percentage (SP), egg surface area (ESA), egg volume (EV), egg contents (EC) and Haugh units (HU) were measured. Repeated measure analysis showed significant (P<0.05) week × diets interaction effect on EW and SW. At week 28, hens on T. esculentum diet had the highest (P < 0.05) EW while those on control diet attained the highest (P < 0.05) EW at week 33. Hens fed I. belina diets had the highest (P < 0.05) SW at week 28. However, at weeks 33 and 38, hens on I. belina diets had the smallest (P < 0.05) SW. Hens fed V. subterranea and T. esculentum diets had significantly lower overall SI compared to those on control and I. belina diets. Tylosema esculentum diets did not promote (P<0.05) ESA, EV and EC. However, no influence (P>0.05) of dietary treatments was observed on overall ST, SP and HU. The inclusion of I. belina and V. subterranea on layer diet had no adverse effects on egg quality while the totally replacement of SBM with T. esculentum as protein source impaired egg quality. These results, suggest that I. belina and V. subterranea could completely replace SBM as protein source in the layer diets without any detrimental effects on egg quality.

“…These finding are in agreement with the findings of Beynen (2004), Celebi and Utlu (2006), (Augustyn et al, 2006) and Aziza et al, (2013). On contrary, Van Elswyk (1997 b), Ansari et al, (2006) and Švedová et al, (2008) reported that linseed oil supplementation in ration of layer decreases egg production.…”

“…Negative effects on bird growth and performance upon including fish oil in broiler diets are well reported and is in agreement with our current results. Dietary fatty acid composition has been reported as the major factor affecting apparent digestibility of fat affecting bird performance . However, it was interesting to notice that feed conversion ratio in CAM + FISH and FISH diet was similar to the control diet.…”

“…Camelina sativa is an oilseed crop of the Brassica ( Cruciferae ) family that has attracted attention in poultry feeding due to its high protein (>35%) and α‐linolenic acid content (>29%) . However, camelina meal (CAM) contains antinutritional factors such as glucosinolates that can affect feed intake, digestibility, and growth in poultry . Although information on feeding different omega‐3 fat sources including CAM on production performance and meat quality aspects are well reported , limited information is available on the effect of dietary omega‐3 fats on GI tract morphological features in broiler chickens.…”

Gastrointestinal morphology, fatty acid profile, and production performance of broiler chickens fed camelina meal (CAM) or fish oil were investigated. One hundred and twenty eight 1‐day‐old Cobb chicks were randomly assigned to one of four treatments. Each treatment was replicated four times with eight chicks (n = 8). The experimental diets were: corn–soybean meal‐based with 3.2% corn oil (control), control + 10% CAM, 10% camelina meal + 3.2% fish oil (CAM + FISH), and 3.2% fish oil (FISH). Villous height (VH) was lowest in the jejunum of FISH and CAM + FISH (p<0.04). Crypt depth (CD) was lowest in the jejunum of Control and CAM (p<0.002). Villous perimeter was higher in control and CAM when compared to CAM + FISH and FISH (p = 0.02). The VH:CD followed the order of control > CAM > CAM + FISH = FISH (p<0.0001). No difference was observed in villus width, surface area, and muscularis thickness. Total omega‐6 fatty acids were higher in the duodenum of control and CAM than FISH and CAM + FISH diets (p<0.0001). Long chain (>20‐C) omega‐3 fatty acids were higher in CAM + FISH and FISH (p<0.0001). No significant differences were detected in the total saturated and total monounsaturated fatty acid content in the duodenum (p>0.05). Weight gain varied significantly and was lowest for CAM + FISH and FISH diets at Day 21 and 42 (p = 0.01). There were no differences in feed intake between control and CAM diets. However, inclusion of fish oil reduced feed consumption (p = 0.019). Feeding camelina meal increased jejunal villus height, villus height: crypt depth and n‐3 fatty acid incorporation in the duodenum when compared to fish oil in broiler diets. Feeding fish oil led to reduction in 42 day body weight.
