“…On the other hand, feeding with tannins seems to be safer and even positive for reproductive events ( Quercus hartwissiana : [ 70 ]; Sesbania sesban : [ 25 ]; Acacia saligna : [ 71 ]; Punica granatum seed: [ 66 ]). Conversely, the tannins group has further biological features than other polyphenolic compounds.…”

Polyphenols in Farm Animals: Source of Reproductive Gain or Waste?

Reproduction is a complex process that is substantially affected by environmental cues, specifically feed/diet and its components. Farm animals as herbivorous animals are exposed to a large amount of polyphenols present in their natural feeding system, in alternative feed resources (shrubs, trees, and agro-industrial byproducts), and in polyphenol-enriched additives. Such exposure has increased because of the well-known antioxidant properties of polyphenols. However, to date, the argumentation around the impacts of polyphenols on reproductive events is debatable. Accordingly, the intensive inclusion of polyphenols in the diets of breeding animals and in media for assisted reproductive techniques needs further investigation, avoiding any source of reproductive waste and achieving maximum benefits. This review illustrates recent findings connecting dietary polyphenols consumption from different sources (conventional and unconventional feeds) with the reproductive performance of farm animals, underpinned by the findings of in vitro studies in this field. This update will help in formulating proper diets, optimizing the introduction of new plant species, and feed additives for improving reproductive function, avoiding possible reproductive wastes and maximizing possible benefits.

“…Results on the effect of feeding level supplementation on intake of basal diets were inconsistent. Mekoya et al (2009) suggested that supplementation of fodder legumes at levels less than 30-40% increases intake of basal hay diets. However, legumes supplementation was reported to reduce the voluntary intake of hay in rams (Dana et al 2000).…”

The aim of the present study was to assess the effects feeding level on body weight changes and semen parameters in adult Sardinian rams reared under intensive conditions in a semi-arid area of southern Italy. During an experimental period of 90 days, 24 healthy Sardinian rams were divided into three equal groups that differed in their feeding level, in terms of concentrate amount. The control-concentrate (CC; n = 8) group received 1.0 times their maintenance requirements, the medium-concentrate (MC; n = 8) group received a diet that supplied 1.2 times their maintenance requirements, and high-concentrate (HC, n = 8) group received a diet that supplied 1.5 times their maintenance requirements. Mixed vetch-oat hay was offered ad libitum to ram groups and water and mineral licks were freely available. Body weight and feed intake was recorded weekly, and semen characteristics were determined every 2 weeks. Dietary treatment affected final body weight (P < 0.01) as feeding level increased. Total dry matter and protein intake changed significantly (P < 0.05 and P < 0.01, respectively) among experimental groups. Semen volume and concentration were positively influenced by feeding level for HC group, whereas no differences were observed in sperm viability and scrotal circumference of rams. It was concluded that dietary level with higher concentrate supplementation resulted in improved body weight gain, feed intake, sperm production, and semen quality in Sardinian rams.

“…Farmers in the present (Chapter 8) and other studies in EA (Dione et al, 2015;Gebretsadik et al, 2014) have reported local practices and perception about the crop management practices in relation to GY, and/or CR quantity, quality and utilization practices and about the role of multipurpose fodder trees (Mekoya et al, 2008). In the present study farmers' generally followed established local agronomic practices (e.g.…”

The role and importance of livestock in smallholder crop-livestock systems and the importance of crop residues (CR) as ruminant feedstuffs in such systems are well established. The effects of genotype (G), environment (E) and crop management (M) factors on yields of grain and CR and the nutritive value of the CR of maize (Zea mays) and common bean (Phaseolus vulgaris) were investigated in an East African context. Genotype effects were examined in early and medium maturing (EM and MM, respectively) maize hybrids and popular varieties of common bean. Environment was examined at three sites for maize in the 2013 and 2014 cropping seasons and at four sites for common bean in 2013. Management effects examined were plant density (D) (5 and 7 plants/m 2 ), height of cutting at harvest in maize, and harvest at early and final seed maturity in common bean. Quality attributes (nitrogen (N), neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents and dry matter digestibility (DMD)) were analysed using near infrared spectroscopy (NIRS) and calibrations expanded and validated with reference samples of CR representing the experimental sample set.There was substantial variation (P<0.05 to P<0.0001) among maize genotypes in yields of grain and stover and quality of stover as a feedstuff. Dual purpose genotypes were identified but G x E interactions for some yield and quality attributes showed that the variation among genotypes can depend on environment. In general the higher D increased yields of grain by 9-15% and stover by 21-31%, but had only minor effects on stover quality attributes. Year (Y) x density (D), G x E and G x D interactions were observed for some of the yield and stover attributes.High cutting height of maize (two internodes below the lowest ear) allowed harvest of most of the stover (on average 63-72% in EM and MM genotypes, respectively) as feedstuff while leaving stubble in the field available for other uses. This is established practice by farmers in some regions. The amount and quality as a feedstuff of the upper and lower stover components varied (P<0.01) among genotypes. N and DMD were 0.05-0.09% and 1.7-3.6%, respectively higher (P<0.0001) in the upper fraction of the stover than in whole stover. Thus evaluation and estimation of the amount and quality of maize stover available as a feedstuff should consider harvest at high cutting height to increase quality. G x E interactions were observed in yield and in some stover attributes in the upper and lower fractions, but these were not consistent.ii Common bean varieties varied (P<0.05 to P<0.0001) in yields of seed and haulm and in the nutritive value of haulm fractions (leaf, stem and pod wall) when harvested at seed maturity. There was extensive leaf loss at seed maturity which decreased haulm quality.Seed and haulm yields were correlated (r=0.87). Seed yield was generally not related to haulm quality as N% or DMD%. The variation in yield and haulm feedstuff quality was also examined in common bean varieties harvested at early se...
