Hassan FU, Arshad MA, Li M, Rehman MSU, Loor JJ, Huang J. Potential of Mulberry Leaf Biomass and Its Flavonoids to Improve Production and Health in Ruminants: Mechanistic Insights and Prospects. Animals (Basel) 2020; 10:E2076. [PMID: 33182363 PMCID: PMC7695318 DOI: 10.3390/ani10112076] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 10/28/2020] [Accepted: 11/04/2020] [Indexed: 12/13/2022] Open
Abstract
Leaf biomass from the mulberry plant (genus Morus and family Moraceae) is considered a potential resource for livestock feeding. Mulberry leaves (MLs) contain high protein (14.0-34.2%) and metabolizable energy (1130-2240 kcal/kg) with high dry matter (DM) digestibility (75-85%) and palatability. Flavonoid contents of MLs confer unique antioxidant properties and can potentially help alleviate oxidative stress in animals during stressful periods, such as neonatal, weaning, and periparturient periods. In addition, mulberry leaf flavonoids (MLFs) possess antimicrobial properties and can effectively decrease the population of ruminal methanogens and protozoa to reduce enteric methane (CH4) production. Owing to its rich flavonoid content, feeding MLs increases fiber digestion and utilization leading to enhanced milk production in ruminants. Dietary supplementation with MLFs alters ruminal fermentation kinetics by increasing total volatile fatty acids, propionate, and ammonia concentrations. Furthermore, they can substantially increase the population of specific cellulolytic bacteria in the rumen. Owing to their structural homology with steroid hormones, the MLFs can potentially modulate different metabolic pathways particularly those linked with energy homeostasis. This review aims to highlight the potential of ML and its flavonoids to modulate the ruminal microbiome, fermentation, and metabolic status to enhance productive performance and health in ruminants while reducing CH4 emission.

Animals (Basel) 2019; 9:ani9050218. [PMID: 31064075 PMCID: PMC6562721 DOI: 10.3390/ani9050218] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 05/03/2019] [Accepted: 05/03/2019] [Indexed: 12/25/2022] Open
Abstract
Simple Summary Rumen is the center of nutrient digestion, absorption and metabolism of ruminants. Ruminal microbes such as cellulolytic bacteria degrade the feed nutrients into smaller molecules, which are absorbed into the body mainly through rumen epithelium. Our study found that mulberry leaf powder supplementation improved the development of rumen epithelium, especially stratum basale, the most important layer of rumen epithelium for the energy metabolism. Our study suggests that supplementing ruminants with mulberry leaf powder may be one of the nutritional strategies that can improve the digestion and absorption performance of ruminants. Abstract Mulberry leaves have been used as a protein source in replacing concentrates of domestic animals, however, little is known about the relationship between supplementation level and the development of rumen epithelium. This experiment aimed to investigate the effects of different proportions of mulberry leaf powder (MLP) in dietary concentrate on rumen fermentation and rumen epithelium morphology in fattening Hu sheep. Forty three-month-old male Hu sheep with an initial body weight of 16.5 ± 0.6 kg (BW ± SD) were chosen and randomly divided into five treatments: 0% (control), 15% (T15), 30% (T30), 45% (T45) and 60% (T60) of MLP in concentrate, respectively. The results showed that the dry matter intake (DMI) and average daily gain (ADG) in treatments T15 and T30 have no significant difference with respect to the control treatment, but DMI and ADG in treatments T45 and T60 were lower than the control treatment (p < 0.05). The apparent digestibility of organic matter (OM) and neutral detergent fiber (NDF) increased linearly and quadraticly as MLP supplementation increased (p < 0.05). The concentration of ammonia (NH3-N) trended to decrease linearly with the increase of MLP supplementation (p < 0.1), whereas the microbial protein (MCP) concentration increased linearly as MLP supplementation increased (p < 0.05). In the results of rumen epithelium morphology, the width of stratum corneum was reduced, whereas the width of ruminal papillae increased (p < 0.05), and the width of stratum granulosum and stratum basale also increased as MLP increased. In summary, MLP supplementation could improve nutrient digestibility, the development of rumen papillae and stratum basale. However, high content MLP (45%–60%) supplementation decreased the growth and food intake performance of fattening Hu sheep. Therefore, 30% MLP is recommended to supplement in concentrate for fattening Hu sheep.

Abstract
Effect of feeding complete pellet feed containing tree leaves on methane emission was studied in male Barbari goats. Three types of complete pellet feed was formulated, viz. control pellet (C) having gram straw (60%) and concentrate mixture (40%), treatment 1 (T1) and treatment 2 (T2) containing dried Leucaena leucocephala and Ficus infectoria leaves respectively. All types of pellets were isonitrogenous. Growing male Barbari goats (12; 3– 4 month-old; average body weight 11.01±0.49 kg) were divided into 3 groups (Gr 1, Gr 2 and Gr 3) as per completely randomized design. Gr 1 was fed with control pellet while Gr 2 and Gr 3 was fed with T1 and T2 pellet respectively. After 6 weeks of experimental feeding, a digestion trial of 6-day duration was conducted. There was no difference in the DMI (g)/day between the 3 groups. Dry matter digestibility and digestibility of other nutrients were comparable among all groups of goats. Rumen liquor was collected from each animal to study rumen fermentation metabolites. Rumen pH, ammonia-N and nitrogenous fractions (total nitrogen, TCA-ppt N, NPN) were statistically similar in all the groups. Total volatile fatty acids (mmol/dl) was significantly higher in Gr 3 (10.57) and Gr 2 (9.52) as compared to control group (8.67). Fractions (%) of volatile fatty acids (acetic acid, propionic acid and butyric acid) were similar in different groups. In vivo methane emission in different groups of goats was estimated by SF6 technique as per procedure standardized in our lab. Methane production (g/day) was 8.29 in Gr 1, 7.47 in Gr 2 and 6.72 in Gr 3. There was 9.89 and 18.93% lower methane production in Gr 2 and Gr 3 as compared to control group of goats fed with complete pellet feed. From the present study, it can be concluded that incorporation of dried L. leucocephala and Ficus infectoria leaves in the complete pellet feed can reduce the methane production in goats.

Abstract
Among the oldest agroforestry systems, silvopastoralism uses shrubs and trees to feed ruminants. The practice is common in extensive livestock production systems, whereas the intensification of grass-based systems in the past century has led to the removal of woody species from agricultural temperate landscapes. In Europe however, woody species are promoted again on grasslands through environment-friendly policies due to the ecosystem services they provide such as carbon sequestration, control of soil erosion, limitation of airborne pollutants and biodiversity conservation. Positive effects of browse on rumen digestion and parasite control have also been documented across different plant species and regions. Under optimal conditions, feeding ruminants from woody fodder sustains animal production. Nonetheless, limitations can restrict the use of woody forage into animal diets, such as the presence of anti-nutritive and toxic compounds. The incorporation of this resource in ruminant feeding systems raises the question of the management of the interface between the plant and the animal. Various management systems are practiced. Temperate species such as Salix spp. and Populus spp. are fed to sheep and cattle in fodder blocks or by pruning trees in New Zealand, and Fraxinus spp. or Corylus avellana in hedgerows supply forage to livestock in Belgium, whereas Leucaena leucocepahala and Desmanthus spp. browsing is common in Australia. Nowadays, ensiling and pelleting techniques are being developed as a way to store browse forage. As the renewed interest in using shrubs and trees to feed ruminants is recent, especially in temperate regions, additional research about the optimal introduction of this resource within systems is needed.

Abstract
The study was conducted in Manyara Region, to determine the effect of concentrate supplementation on growth performance and foraging behavior of zebu steers. Twenty zebu steers were distributed equally into two dietary groups: pasture + concentrate (PS) and natural pasture alone (NP). The animals' body weight and body condition scores were estimated every 2 weeks. The focal observation technique was used to determine grazing behavior. The average daily gain (ADG) was significantly higher (P ≤ 0.05) in the PS than in the NP. Significant less time (P ≤ 0.05) was spent in feeding by animals in the PS than those in the NP. Significant less bite rates (P ≤ 0.05) were also observed in the PS than in the NP. The most highly abundant forage species exhibited low CP contents but were most frequently eaten by the focal animals. Strategic supplementation with locally available concentrates is recommended for profitable ruminant productivity and environmentally friendly grazing strategy.

Abstract
In vitro gas production with and without polyethylene glycol (PEG) of the fruits of Crescentia alata and Guazuma ulmifolia was evaluated, the degradation kinetics of lamb diets with added fruit of the tree was determined, and the ration intake and growth rate of lambs fed these diets were measured. Twenty-five entire male lambs of 23.5 ± 0.44 kg body weight were used and distributed in treatments: T0 (control without fruit); T1 and T2, 15 and 30 % of the fruit of C. alata; and T3 and T4, 15 and 30 % of the fruit of G. ulmifolia. Data variables chemical composition, fermentation kinetic, and digestibility in vitro were analyzed by a completely randomized design and data production response factorials design of five treatments by three evaluation periods. The total phenolic content (TP) (23.0 g/kg DM) was higher (P < 0.01) in the fruits of G. ulmifolia. The addition of PEG increased (P < 0.05) in vitro gas production (156.6 mL/g DM) in fruits of G. ulmifolia. In the fermentation kinetics, the total gas volume was higher (P < 0.01) at T0 (b = 293 mL/g DM), and the rate of degradation (c) but Lag time (t lag) was not different. In animal response, total dry matter intake was higher in lambs that received T4 (1.35 kg), and the daily weight gain and feed conversion did not differ (P > 0.05) among lambs receiving the treatments. Thirty percent G. ulmifolia fruit added in the diet increased dry matter intake and improved feed conversion but did not increase weight gain.

Abstract
The present study was carried out to evaluate the effect of sweet sorghum stover (cost $0.05/kg) supplementation as complete balanced diet (at 60 % level) on sheep performance, carcass characteristics and economics in comparison to maize stover (cost $0.08/kg) and sorghum stover (cost $0.09/kg) (conventional roughage sources). Eighteen Nellore ram lambs aged about 3 months (average body weight 15.65 ± 0.10 kg) were randomly allotted to three complete diets formulated with roughage to concentrate ratio of 60:40 (on dry matter basis) using sorghum stover (SS), maize stover (MS) and sweet sorghum stover (SSS) as roughage sources for a period of 120 days. The average daily dry matter intake (g/kg w(0.75)), average daily gain (grams) and feed conversion efficiency were similar among the experimental diets. No significant differences were observed among the treatment groups for the mean live weight (kg) at slaughter, empty body weight (kg) dressing percentage on live weight basis or on empty body weight basis, proportion of different wholesale cuts, percentage of edible offals and non-edible offals, proportion of meat, meat/bone ratio and chemical composition of meat. Thus, it can be concluded that sweet sorghum stover can be incorporated in the complete diets of lambs by replacing conventional roughages such as sorghum stover and maize stover processed as mash form without affecting the performance, nutrient digestibility and carcass characteristics.

Abstract
The study was carried out to assess the effect of condensed tannins (CT) supplementation through leaf meal mixture (LMM) on feed intake, humoral [Immunoglobulin G (IgG)], cell mediated immune response (CMI) and faecal egg counts in Haemonchus contortus infected sheep. Eighteen sheep were randomly divided into three groups (negative control-NC, infected control-C and Infected treatment-T) of six animals in each group in a completely randomized block design for a period of 90 days. Twelve H. contortus infected adult sheep were allocated into two equal groups C and T, supplemented with 0 and 1.5 % of CT, respectively. Six non-infected sheep of similar age and body weight of NC group were included in this study to compare their immune response with H. contortus C and CT supplemented T groups. Intake of dry matter and organic matter (g day(-1) and % live weight) was statistically similar (P < 0.05) among the three groups. The anti-Haemonchus IgG and CMI response was higher in T group as compared to C group. The mean faecal egg counts was significantly (P < 0.001) higher in C group as compared to T group. It may be concluded that dietary supplementation of CT (1.5 %) through LMM improved humoral and CMI immune response and decreased worm load in H. contortus infected sheep.

Abstract
This study was conducted to examine the effects of condensed tannins (CT) from Ficus bengalensis leaves on the feed utilization, milk production and health status of crossbred cows. Eighteen crossbred dairy cows at their second and mid lactation (avg. BW 351.6±10.6 kg) were randomly divided into two groups of nine each in a completely randomized block design and fed two iso-nitrogenous supplements formulated to contain 0% and 1.5% CT through dried and ground leaves of Ficus bengalensis. The diets were designated as CON and FBLM, respectively and fed to cows with a basal diet of rice straw to meet requirements for maintenance and milk production. The daily milk yield was significantly (p<0.05) increased due to supplementation of FBLM diet. The 4% fat corrected milk yield was also significantly (p<0.01) higher due to increased (p<0.05) milk fat in cows under diet FBLM as compared to CON. The inclusion of CT at 1.5% in the supplement did not interfere with the feed intake or digestibility of DM, OM, CP, EE, NDF, and ADF by lactating cows. Digestible crude protein (DCP) and total digestible nutrients (TDN) values of the composite diets were comparable between the groups. The blood biochemical parameters remained unaltered except significantly (p<0.05) lowered serum urea concentration in cows fed FBLM diet. There was a significant (p<0.05) increase intracellular reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activity in cows supplemented with condensed tannins. The total thiol group (T-SH) was found to be higher with reduction in lipid peroxidation (LPO) in cows of FBLM group. The cost of feeding per kg milk production was also reduced due to supplementation of Ficus bengalensis leaves. Therefore, a perceptible positive impact was evident on milk production and antioxidant status in crossbred cows during mid-lactation given supplement containing 1.5% CT through Ficus bengalensis leaves.

Abstract
The study assessed the effect of dietary supplementation of leaf meal mixture (LMM) containing condensed tannins (CT) on feed intake, nutrient utilization and performance of sheep infected with Haemonchus contortus. Eighteen adult sheep of similar age and body weight (25.03±1.52) were included in this study and out of these, 12 sheep were infected with single dose of infective third stage larvae of H. contortus at 2,000 larvae per sheep. The experimental sheep were allocated in three different groups' i.e. negative control (NC; no infection), control (C; H. contortus infected) and treatment (T; H. contortus infected+CT at 1.5% of the DM through LMM) and the experiment was conducted for a period of 90 d. The intake of dry matter (DM), organic matter (OM) and digestibility of DM, OM, neutral detergent fibre (NDF) and acid detergent fibre (ADF) were comparable among three animal groups. However, digestibility of crude protein (CP) and ether extract (EE) were significantly (p<0.05) higher in NC group as compared to both C and T groups. Nitrogen (N) retention (g/d or % of N intake) was significantly (p = 0.038) lower in C group as compared to T and NC groups. Daily intake (g/kg W(0.75)) of digestible crude protein (DCP), digestible organic matter (DOM) and total digestible nutrient (TDN) did not differ significantly (p<0.05) in the three groups. Haemoglobin (Hb) and packed cell volume (PCV) were significantly (p<0.001) higher in treatment group as compared to control. The level of Hb and PCV reduced (p<0.001) after 30 days of experimental feeding. CT significantly (p<0.001) reduced serum urea in T group as compared to NC and C groups. Serum proteins differed significantly (p<0.01) among the three groups. The activity of serum enzymes AST, ALT, ALP and LDH were also statistically non significant (p<0.05) among treatments. The weight of abomasal lymph nodes (ALN) in T group was higher (p<0.05) than in C group. Treatment group had lower (p<0.05) total worms and fecal egg count compared to control group. It may be concluded that dietary supplementation of CT through LMM significantly improved the N retention, and inhibited the different developmental stages of Haemonchus contortus in experimental sheep.

Abstract
Four, ruminally fistulated crossbred (Brahman×native) beef cattle with initial body weight of 420±15 kg were randomly assigned according to a 4×4 Latin square design. The dietary treatments were mulberry leaf pellet (MUP) supplementation at 0, 200, 400 and 600 g/hd/d with rice straw fed to allow ad libitum intake. All steers were kept in individual pens and supplemented with concentrate at 5 g/kg of body weight daily. The experiment was 4 periods, and each lasted 21 d. During the first 14 d, all steers were fed their respective diets ad libitum and during the last 7 d, they were moved to metabolism crates for total urine and fecal collection. It was found that increasing MUP levels resulted in linearly increasing rice straw and total intakes (p<0.05). Ruminal temperature and pH were not significantly affected by MUP supplementation while NH3-N concentration was increased (p<0.05) and maintained at a high level (18.5 mg/dl) with supplementation of MUP at 600 g/hd/d. Similarly, viable total bacteria in the rumen and cellulolytic bacteria were enriched by MUP supplementation at 600 g/hd/d. However, the rumen microbial diversity determined with a PCR-DGGE technique showed similar methanogenic diversity between treatments and sampling times and were similar at a 69% genetic relationship as determined by a UPGMA method. Based on this study, it could be concluded that supplementation of MUP at 600 g/hd/d improved DM intake, ruminal NH3-N, and cellulolytic bacteria thus iimproving rumen ecology in beef cattle fed with rice straw.

Abstract
A study was conducted to estimate dry matter (DM) degradability in the rumen of lambs offered a basal soybean meal and sorghum grain diet with three levels of white mulberry (WM) leaves (Morus alba). Diets consisted of 90% concentrate and 10% sorghum straw, which was incrementally replaced by WM leaves at 0% (control diet, T1), 2.5% (T2), and 5% (T3) of the total ration. Crude protein (CP) in WM was 21.8% (DM basis). Diets had equal CP (14% DM basis) and metabolizable energy (10.8 MJ/kg DM) content. Three non-castrated Pelibuey male lambs fitted with permanent rumen cannula were utilized in a 3 × 3 Latin square design. Each experimental period consisted of 10 days of adaptation followed by sampling. DM degradability was determined using the nylon bag technique. Bags contained the experimental diets offered in each period and were incubated in rumen in pairs for 4, 8, 12, 24, and 48 h. The potential degradation was higher (P < 0.05) for T2, followed by T3 and T1. WM level did not influence the degradation rate or the effective degradation at the three passage rates modeled. It was concluded that WM forage may have useful application in feedlot diets for growing lambs, as this forage increases potential degradation of high-grain diets. The incorporation of WM in diets for feedlot lambs in tropics may reduce the use of expensive conventional protein supplements.
