“…Similar procedures have also been developed by others (Appelgate and Herschberger, 1969;Drogoul et al, 1995;Miraglia et al, 1988). Key features of our use of the IST in the caecum of equines are as follows: up to 4 porous in situ bags (6.5 Â 20 cm) containing feed sample are suspended in the caecum for a range of incubation times (e.g.…”

“…The knowledge of horse nutrition has followed the feed evaluation techniques applied to other species (Hyslop et al, 2006). The in situ technique was first developed for swine, applied to ruminants, and then methodological adaptation for horses allowed assessment of the dynamic of feed degradation at segments of the horse's gastrointestinal tract (Koller & Hintz, 1978;Udén & Van Soest, 1984;Miraglia et al, 1988;Moore-Colyer et al, 2002;Hyslop, 2006).…”

-The present study was carried out to evaluate the in situ degradation of dry matter (DM), neutral detergent fiber (NDF) and crude protein (CP) in roughages by the in situ caecal digestion technique in horses. The roughages evaluated were: Lucerne hay (Medicago sativa), peanut (Arachis pintoi cv. Amarillo), desmodio(Desmodium ovalifolium), stylo (Stylosanthes guianensis cv. Mineirão), pigeon pea (Cajanus cajan), lime-yellow pea (Macrotyloma axillare) and coastcross hay (Cynodon dactylon cv. coastcross). The assay was conducted in a complete randomized design with seven roughages and three replications. One mare with a cannula fitted in the caecum was used, fed diet consisting of coastcross hay (80%) and concentrate (20%) at 2.0% BW, four times a day. Nylon 6.5 × 20 cm bags were used with 45 μ/pore, containing 5. Key Words: cannula, digestion, fiber, forage, legume Degradação cecal in situ de alimentos volumosos em equinos RESUMO -Objetivou-se avaliar a degradação da matéria seca (MS), fibra em detergente neutro (FDN) e proteína bruta de alimentos volumosos pela técnica da digestão cecal in situ em equinos. Avaliaram-se as forrageiras: feno de alfafa (Medicago sativa), amendoim forrageiro (Arachis pintoi cv. Amarillo), desmódio (Desmodium ovalifolium), estilosantes (Stylosanthes guianensis cv. Mineirão), guandu (Cajanus cajan), macrotiloma (Macrotyloma axillare) e feno de coastcross (Cynodon dactylon cv. coastcross). O ensaio teve duração de 35 dias e foi realizado em delineamento inteiramente casualizado com sete alimentos e três repetições. Utilizou-se uma égua fistulada no ceco, alimentada com dieta composta por feno de coastcross (80%) e concentrado (20%), fornecida quatro vezes ao dia em quantidade equivalente a 2% do peso vivo. No ceco, foram inseridos 3 a 4 sacos de náilon de porosidade 45 μ de 6,5 × 20 cm, contendo 5,2 g de MS/saco, nos tempos de 2, 4, 6, 8, 12, 24 e 48 horas de incubação. Os parâmetros de degradação da MS de todos os volumosos foram significativos. Não houve ajuste no modelo de degradação da PB e FDN do guandu. O amendoim, estilosantes e macrotiloma apresentaram maior fração potencialmente degradável da MS, com valores de 53, 46,5 e 40%, respectivamente, e os maiores valores da fração solúvel de 20, 21, 28,6%, além de elevadas taxas de degradação (10,36, 20,26 e 14,8%h -1 ). Nestes alimentos, também foram observadas as maiores taxas de degradação da FDN (9,1 e 11,3, 11,2%h -1 ), das frações potencialmente degradáveis (55, 51,8 e 47,2%) e as mais altas taxas de degradação da PB em 48 horas de incubação (87, 95, 94,8%, respectivamente). O amendoim forrageiro, o estilosantes e o macrotiloma apresentam potencial de uso nas dietas para equinos.Palavras-chave: cânula, digestão, fibra, forrageiras, leguminosa R. Bras.

“…The digestibility of horse feeds and rations can be determined or predicted using different direct or indirect techniques: calculations based on the chemical composition of feeds (Martin-Rosset et al, 1996a), in vivo (Miraglia et al, 1988(Miraglia et al, , 1999a(Miraglia et al, , 1999b or in vitro (Andrieu et al, 1996;Martin-Rosset et al, 1996b;Macheboeuf et al, 1997) methods. The total collection of faeces method is considered to be the most accurate and it has been tested extensively on a large numbers of feeds, with a significant number of horses to perform original table of nutritional value of feedstuffs in Europe such as those of INRA (1984 and.…”

The digestibility of horse feeds and rations can be determined using different techniques such as calculations based on the chemical composition, in vivo or in vitro methods. The marker methods overcome difficulties like discomfort for the animals and longer experimental times encountered using the ingesta/egesta method. In field conditions, a natural indigestible marker like acid-insoluble ash (AIA), with no changes in the normal ration, could be a very useful tool for digestibility trials. A group of six standardbred horses was used in a set of seven apparent digestibility trials. The diets were based on a first-cut meadow hay added to three different cereals (barley for trials 1 and 2; oats for trials 3 and 5 and corn for trials 6 and 7), the hay : concentrate ratio being 60 : 40 or 70 : 30 on a dry matter basis. Feedstuffs and faeces were analysed to determine the AIA content, using 2N HCl or 4N HCl technique. No differences about AIA concentration were found between the two methods for means and accuracy in each diet. Digestion coefficients for each diet did not differ with AIA method, even if in some trials interfering factors consistently lowered the overall values. Consequently, the AIA 2N HCl can be considered the easier and cheaper method to state apparent digestibility in field conditions, and a good tool for digestibility trials in horses fed hay-based diets.
