“…Boufennara et al 2012). Proximate and fatty acid (FA) composition, phenolic concentration and digestibility have been largely assessed for various fodder tree species in several environments such as savanna (Tefera et al 2008), tropics (Arigbede et al 2012), subtropics (Prakash et al 2009), American temperate region (Ricklefs and Matthew 1982), Mediterranean region (Kökten et al 2012) and non-European alpine areas (Khanal and Subba 2001).…”

Temporal variations in leaf traits, chemical composition and in vitro true digestibility of four temperate fodder tree species

et al. 2020

Context Many tree and shrub species are underestimated fodder resources due to insufficient knowledge about their potential feeding value, especially for goats. Aims The present work aimed at assessing productive and nutritional attributes of the foliage of the following four temperate tree species widespread in Europe: Acer pseudoplatanus, Fraxinus excelsior, Salix caprea and Sorbus aucuparia. Methods Leaf length and biomass, proximate composition, fatty acid profile, phenolic composition and in vitro true dry matter digestibility were determined along the vegetative season. Key results The leaf length of the four species was significantly related to leaf biomass and can be considered as a proficient proxy for estimating leaf biomass. The differences found among the species were remarkable, although weakly related to temporal changes, especially when considering fatty acid and phenolic compositions. Fraxinus excelsior sprouts were the most productive, with a mean biomass of 13.2 g dry matter (DM) per sprout at the end of the growing season. Its foliage showed also the lowest phenolic concentrations (average total extractable phenols of 11.25 g/kg DM), resulting in the highest digestibility values (average in vitro true dry matter digestibility of 56.5 g/kg DM). Digestibility of S. aucuparia was similar, but its lower polyunsaturated fatty acid concentration (average value of 62.13 g/kg DM) could reduce the interest for this species as a feeding resource for goat dairy products with healthy properties. The lower digestibility found for A. pseudoplatanus and S. caprea (average values of 43.3 and 46.2 g/kg DM, respectively) may be related to their higher phenolic concentrations (average total extractable phenols of 45.9 and 47.3 g/kg DM, respectively). Conclusions The four species could represent an appealing feedstuff for goat nutrition, due to the valuable and complementary nutritional characteristics of their foliage. Implications The use of the studied species as fodder resource may be particularly relevant during drought periods and in the late summer when herbage quality decreases, especially in terms of crude protein and fatty acid profile.

“…Although the digestive tract of goats is anatomically similar to that of sheep and cows, goats have a large physiological capacity to adapt to high tannin levels in the diet. In vivo and in vitro studies conducted revealed that goats are more efficient than sheep digesting feedstuffs with low nitrogen, high fiber or high tannin contents of tree fodders and shrubs (Salem et al, 2006;Tefera et al, 2008). There are some comparative studies in the in vitro digestibility and fermentability of forages using sheep, goats and cow's rumen fluid as inoculums sources, but few comparisons between cows and goat have been reported up to date (Calabró et al, 2004;Mould et al, 2005;Salem, 2005).…”

“…Tree pods could therefore be collected and used as dietary supplements during the dry season. Most browse pods are reported to be rich in protein (Tanner et al, 1990;Ncube and Mpofu, 1994), and play an important role in maintaining year-long productivity of livestock in the semi-arid rangelands (Tefera et al, 2008).…”

Effects of supplementation and milking of Matebele does four weeks pre-partum to weaning, on milk yield, kid birth weight and growth rate were studied. Forty does were divided into four treatments: supplemented and milked (SM), supplemented and not milked (SNM), not supplemented and milked (NSM); and not supplemented and not milked (NSNM). Supplemented goats were given 200 g/doe/day of Dichrostachys cinerea pods containing 19% CP. The study was carried out in September during time of feed unavailability and animals were grazed on rangelands for seven hours before being given the supplement. Fifty-six kids were born from all the experimental animals and 24 were singles whereas 32 were twins. Milk yield was higher (P < 0.05) in supplemented than non-supplemented does. Although supplementation had no effect on kid birth weights, growth rates were higher (P < 0.05) in the SNM group (103 +/- 10.1 g/day) than in the SM group (74 +/- 10.8 g/day). Among the non-supplemented groups, kids from milked does had higher (P < 0.05) daily gains (85 +/- 10.9 g/day) than those from non-milked does (67 +/- 10.7 g/day). Weaning weights were higher (P < 0.05) in SNM does (12.8 +/- 1.30 g/day) than in the SM does (10.2 +/- 1.17 g/day). Among kids from the non-supplemented does, those from milked does had superior (P < 0.05) weaning weights (11.2 +/- 1.23 g/day) than those from non - milked does (9.2 +/- 1.27 g/day). Mortalities were also lowest in kids born from SNM does. It is concluded that pre-partum to weaning supplementation generally increases milk production which then increases kids growth rates and weaning weights, as well as reduce kid mortalities.
