“…The DUC of hemi-cellulose exhibited the lowest value with dehydrated hay (P<0.01). The levels of gross energy and the coefficients of energy utilisation according to Martin-Rosset's equation (DUC DE1 ) [7] and AIA (DUC DE2 ) are reported in Table 6.…”

“…The coefficient of digestible utilisation (DUC) of nutrients was calculated according to the AIA method. The energy DUC calculated with AIA was compared with the one obtained using the equation reported by Martin-Rosset et al [7]. The DUC data were subjected to analysis of variance using the JMP (SAS system) [11] following the method that maintains two separate groups (P and C) according to the model:…”

In the last twenty years, the increased interest in breeding jumping horse has not been paralleled by research into their energy requirements. A crucial factor in breeding race horses is the quality of the ration, which must sustain and promote high performances. In addition to the energy required for maintenance, energy needs depend on muscular, skeletal, respiratory and cardiovascular system activity. The energy expenditure related to work performed depends on effort duration and intensity, but it may be affected by the effect of the lack of oxygen at the end of the work, increased energy requirement as a reaction to "stress", and a general increase in metabolic rate. Formulation of a diet that meets the nutrient requirements of athlete horses must also consider the effects of the combination of different dietary components. The present research was carried out in jumping horses to evaluate the nutritional value and t h e d ig e s t i bi l i t y o f t h r ee types of roughages administered with two different feedstuffs.

“…The feed was provided once a day, in quantities exceeding the requirements of foals, that is, ad libitum. Feed requirements, estimated for foals ageing 6 to 12 months and weighting 500 kg, were 8.5 kg/day of dry matter (DM), 1.217 kg/day of CP, 28 Mcal/day of digestible energy and 6.9 horse feed units/day of net energy (Martin-Rosset et al, 2006;National Research Council (NRC), 2007). The LPF and LPM were fed a diet containing 10.6% of CP on DM; the HPF and HPM received a diet containing a normal CP content, that is, 13.2% CP on DM (Mantovani et al, 2014).…”

The present work is aimed at evaluating the behaviour of Italian Heavy Draught Horse (IHDH) foals reared in semi-covered stables and fed two isoenergetic total mixed rations with different dietary protein levels (13.2% and 10.6% of CP on dry matter). The study was prompted by the restrictions for nitrate emissions in farms of the European Nitrate Directive. One suggested solution is to reduce dietary protein while maintaining normal performance and welfare, but there is a lack of literature in studies of horses. The behaviours of 20 foals of 437 ± 60 kg of BW, aged 379 ± 37 days and stabled in four pens by sex (S) and diet (D) were video recorded and analysed to build a suitable ethogram including 18 behaviours in six categories: ingestion, resting, maintenance, movement, social activities, other. The percentage of the daily time spent in each behavioural category and single behaviours was analysed via a single traits GLM including S, D and their interaction. Daily activity was consistent with existing literature: foals spent about 33% of the day in ingestion activities and 41% in resting, whereas social interactions constituted 8% of the time and individual maintenance <2%. Concerning diet, foals fed high protein spent more time in movement (19.62 ± 0.73% of day v. 10.45 ± 0.73% in low-protein (LP) foals; P ⩽ 0.001), whereas the LP group increased resting (43.42 ± 1.12% v. 38.02 ± 1.12%; P ⩽ 0.001). No stereotypies were found, and daily activity followed the typical values for draught breeds for foals in both dietary groups, a result that suggests the maintenance of well-being after dietary protein reduction. This result, together with the findings of a companion study showing no changes in growth performances of foals, showed that a reduction of CP in foal diet is reconcilable with the maintenance of performance and welfare.

“…Attention was paid, in course of the studies, to the propriety of horse feeding, to the need for a precise estimation of its demand, especially in animals either intensively exploited or for reproduction purposes (Martin-Rosset et al 2006, Coenen et al 2011. It is noteworthy, however, that the best indicator of this propriety is the animal's condition, whose assessment requires knowledge and experience (Christie et al 2006).…”

The aim of the study was to assess the welfare, using the Welfare Quality criteria, of horses maintained in natural conditions. The study material was a herd of Hucul horses, consisting of 14 mares with offsprings and a stallion, maintained in a herd system on pastures. The research was conducted in the months of March, July and November in 2010 and 2012. Nutrition assessment was based on access to feedstuff, water, including their state. Analysis of levels of maintenance involved evaluating prevailing weather conditions, stocking rate as well as horses' freedom of movement in the delineated land area. Assessment of the herd's health condition was based on interviews with the supervising veterinarian. Horses' behaviour was assessed through observations that relied on their social, affiliative and agonistic behaviours. The condition of the horses was influenced by the period of year, with the best being in November (P≤0.01). Maintenance conditions and exploitation affected the herd's state of health, with no illnesses or injuries being reported over the analysed period. Seasons of the year had impacts on the horses' behaviour (P≤0.01). In summer, grazing took place in the late evenings and early mornings, with animals kept under sheds. Intensified feeding was observed in November. No stereotypical behaviours were observed. Heart rate measurements were a pointer to the animals' emotional balance and attitudes towards people. The observed high level of horses' welfare suggested that a natural herd system of management ought to be preferred and propagated.
