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.

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.

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.

Growth rate assessment is an important husbandry practice often carried out in livestock breeding and fattening. Meat production is the most important trait in the breeding objectives of sheep production. Useful information on the suitability of the animals for meat production could be evaluated on a morphological basis. The aim of this study was to investigate breed differences in liveweight, carcass traits and muscle distribution for meat characteristics among Balami (BA), Uda (UD), Yankasa (YK) and West African Dwarf rams (WAD). A total of forty-eight rams were randomly assigned into four groups of twelve rams per breed in a completely randomized design. Body linear measurements were obtained weekly during the fattening period. At the end of the feeding trial, animals were subjected to an 18-hours fast and slaughtered for carcass measurements and muscle distribution. Results showed that BA and UD had higher values for body length (115.75±4.25 and110.25±1.89cm), withers height (70.50±5.57and69.00±2.16cm) and heartgirth (92.00±2.94and84.00±1.41cm), than YK (96.50±3.87, 60.75±3.30 and 76.75±0.96cm), respectively which in turn had higher values than WAD (86.50±5.20, 53.25±5.32 and 75.25±3.30cm). Carcass length, pistol length, and leg length were75.75±4.79,60.75±7.14 and 88.00±2.16; 75.50±4.66, 56.00±5.00 and 80.25±5.80; 59.00±7.79, 56.00±10.62 and 71.50±2.65; 60.50±3.11, 53.75±5.91 and 61.00±2.94cm for BA, UD, YK and WAD rams, respectively. BA and UD had higher proportion of muscle distribution and were generally better than the YK and WAD breeds. This may boost their potential for large scale meat production under fattening conditions.

A twenty-eight (28) day feeding trial was conducted to determine the nutrient composition of biodegraded sweet orange (Citrus sinensis) fruit peel and its potential as an energy source in the nutrition of starter broiler chicks. Rumen content was collected from freshly slaughtered cattle and, fresh sweet orange fruit peels (SOP) were collected from orange fruit retailers. The rumen content was mixed with water at ratio 1kg: 1Land sieved to obtain rumen filtrate (RF). The fresh sweet orange peels were divided into four equal parts in weight; T1, T2, T3 and T4, and soaked in the rumen filtrate at ratio 1 kg: 1 L in air-tight bags for 12 h, 24 h, 36 h and 48 h, respectively. The biodegraded sweet orange peels (BSOP) were sun-dried to a moisture level of about 10%, milled and each used to replace 30% of maize in the control diet (CD) to obtain broiler starter test diets T1D, T2D, T3D and T4D, respectively. Chemical analyses were carried out to determine their proximate composition and fibre fractions while, metabolizable energy content was calculated. The results showed that BSOP contained CP, CF, EE, Ash, NFE and metabolizable energy in the range of 6.78%-7.30%, 10.36%-12.30%, 1.88%-2.65%, 7.79%-11.76%, 66.04%-72.46% and 2829.44 kcal/kg-3037.97 kcal/kg, respectively. The BSOP had ADF, NDF, ADL, hemicellulose and cellulose in the range of 19.50%-22.50%, 52.30%-56.70%, 6.80%-8.40%, 32.80%-34.20%and 12.90%-14.40%, respectively. A total of one hundred and eighty day old broiler chicks (Ross 308) were randomly assigned to five dietary treatments replicated three times with equal number and similar weights in a completely randomized design. The experimental diets had significant (p 0.05) and inferior values to the birds on the maize based control diet suggesting that time duration of 12 h, 24 h, 36 h and 48 h given for biodegradation of sweet orange peel could not enhance its nutrients. Biodegradation of sweet orange fruit peel for a time frame of 12 h to 48 h yielded a feed ingredient with a relatively high crude fibre, which lowered the growth rate of starter broiler chicks and cannot be used to formulate starter chicks diet at 30% maize replacement.

Oluremi, Favour Bette Patrick Abang","doi":"10.11648/J.AVS.20200805.13","DOIUrl":"https://doi.org/10.11648/J.AVS.20200805.13","url":null,"abstract":"A twenty-eight (28) day feeding trial was conducted to determine the nutrient composition of biodegraded sweet orange (Citrus sinensis) fruit peel and its potential as an energy source in the nutrition of starter broiler chicks. Rumen content was collected from freshly slaughtered cattle and, fresh sweet orange fruit peels (SOP) were collected from orange fruit retailers. The rumen content was mixed with water at ratio 1kg: 1Land sieved to obtain rumen filtrate (RF). The fresh sweet orange peels were divided into four equal parts in weight; T1, T2, T3 and T4, and soaked in the rumen filtrate at ratio 1 kg: 1 L in air-tight bags for 12 h, 24 h, 36 h and 48 h, respectively. The biodegraded sweet orange peels (BSOP) were sun-dried to a moisture level of about 10%, milled and each used to replace 30% of maize in the control diet (CD) to obtain broiler starter test diets T1D, T2D, T3D and T4D, respectively. Chemical analyses were carried out to determine their proximate composition and fibre fractions while, metabolizable energy content was calculated. The results showed that BSOP contained CP, CF, EE, Ash, NFE and metabolizable energy in the range of 6.78%-7.30%, 10.36%-12.30%, 1.88%-2.65%, 7.79%-11.76%, 66.04%-72.46% and 2829.44 kcal/kg-3037.97 kcal/kg, respectively. The BSOP had ADF, NDF, ADL, hemicellulose and cellulose in the range of 19.50%-22.50%, 52.30%-56.70%, 6.80%-8.40%, 32.80%-34.20%and 12.90%-14.40%, respectively.
