Abstract: The potential for the utilization of Mucuna seeds as an alternative source of protein was evaluated by presoaking in water then in sodium bicarbonate solution + boiling treatment on the one hand and isolating protein technique on the second hand on the growth and hematological performances of broilers. A total of 135 one-day-old Cobb500 broilers, divided into three groups of 45 animals each were randomly allocated to three treatment diets with 3 replicates (n=15/replicate) each per treatment and fed ad libitum with three iso-protein diets: Diet 1 (RTS) given to the Control batch contained soya bean meal and this principal protein source was completely replaced by M. pruriens seeds meal in Diet 2 (RFM) and by protein isolated from M. pruriens in Diet 3 (RIM) given to batches 2 and 3 respectively. Results revealed that FI, ADG, PER, Carcass yield, Hb and Hct were comparable but significantly (p<0.05) low in broilers fed RFM (77.01 g/26.16 g/1.99/68.69%, 11.98 g/dL/28.46% respectively) and RIM (76.98 g/25.88 g/2.08/67.61%, 12.05 g/dL/28.28% respectively) diets and also in all characteristics of the digestive tract. The inverse trend i.e. highest (p<0.05) but comparable values of Heart (0.74 g/RFM; 0.77 g/RIM) was observed in these same animals; Birds fed RIM diet registered the lowest (p<0.05) BWG (711.04 g) and LW (799.65 g) but the highest (p<0.05) FCR (3.45). These results suggest that meal and protein isolate of M. pruriens seeds could be valorised in broiler diet subject to further investigations in growth-finishing phase.

Abstract: The objective of this study was to quantify the effect of a combined calcium, magnesium and anti-oxidant bolus on early lactation energy status and milk production performance of multiparous dairy cows compared to control, and calcium only bolus intervention. Multiparous (n=91) cows from a large Irish dairy herd, with a below-average incidence of hypocalcaemia, were enrolled in this study and randomly assigned to either a control (CON, n=30), a calcium only bolus (ABC, n=30) or a combined calcium, magnesium and anti-oxidant (Cow Start calcium) bolus (CSC, n=31). CON cows received no bolus and ABC and CSC cows received two boluses at 0- and 12-hours post-partum. Early lactation energy status was studied by recording milk ketone (beta hydroxybutyrate (BHBA)) levels at day 14 and day 28 post-partum, body condition scoring (BCS) of cows at week 0, 2, 4, 6, 8 and 12 post-partum and by weighing cows at week 0, 2, 4, 6 and 8 post-partum. Cows in the CSC group recorded significantly (P < 0.05) lower milk BHBA levels (0.43 mg/dL) when compared to CON (0.98 mg/dL) and a trend (P < 0.10) towards lower milk BHBA when compared to ABC (0.74 mg/dL). The CSC group also showed a trend (P < 0.07) towards reduced body condition loss between calving and nadir (- 0.39 BCS units) when compared to ABC (- 0.53 BCS units). Milk production volumes were significantly increased (P < 0.05) by 1.3kg per day from day 5 of lactation until day 90 for the CSC group (30.7kg/day) when compared to CON (29.4kg/day), with a trend (P < 0.10) of 0.8 kg per day toward higher milk production when compared to the ABC group (29.9 kg/day). Body weight change (kg), Milk Fat % and kg, Milk Protein % and kg, fat:protein ratio, combined milk components (milk fat and milk protein kg), and energy corrected milk were recorded and analysed, with no significant differences observed. Results of this study indicate that cows supplemented with the CSC bolus responded favourably to treatment with regard to improved metabolic status in the critical early lactation post-partum period when compared to control and a calcium only bolus intervention. Results of this study suggest that supplementing dairy cows with a combined calcium, magnesium and antioxidant oral boluses will have beneficial effects for early lactation dairy cows.

Abstract: The essay assessed Borassus aethiopum (B.a) ripe fruits’ dried pulp effect on egg yolk coloration. First, thirty-six Harco laying hens, 42 weeks old with similar weight (α=0.05) were allotted in 12 cages of 4m2 (2m x 2m, respectively for length x width) each. Second, 4 laying hens’ diets were formulated; a yellow corn-based diet (YC), a white corn-based diet (WC), a white corn-based diet supplemented with 10% of B.a mature fruits’ dried pulp (WC+10%B.a), and finally a white corn-based diet supplemented with 20% of B.a ripe fruits’ dried pulp (WC+10%B.a). During the evaluations, similar eggs for weights were analyzed. As a result, rich pigment diets formed a group and produced the heaviest egg yolk compared to the WC diet, for 13.94+0.16 g versus 13.64+0.16 g. Whereas, WC diet delivered the heaviest albumin weights, 31.92+0.33 g versus 29.27+0.33 g for WC+10%B.a which had the lightest weight. Looking at eggs’ yolks color, Roche yolk color fan distinguished just 2 levels whose were the pale egg yolk from WC graded 1, and the intense colored yolks group graded 6. A spectrophotometer reflectance method helped for better yolks color distinctions. The yolks’ yellow colors from WC+10%B.a (b*=52.29), WC+20%B.a (b*=52.49) and YC (b*=52.22) were similar (p=0.7278). But, the WC+10%B.a diet egg yolk color was significantly higher than that of WC (b*=20.70; p<0.0001). In conclusion, Borassus aethiopum mature fruits’ dried pulp can be incorporated into laying hens feed as natural pigments’ source.
