Soaked unmolassed sugar beet pulp as a partial forage replacer in equine diets when ponies are offered grass hay ad libitum

There is increased interest, in using sugar beet pulp (SBP) products in equine diets as a major source of fibre in place of traditional forages. It has been observed that voluntary feed intake (VFI) was lower when SBP products were included in the diet of dry sows compared to other fibrous foodstuffs (Brouns, et al 1995). Equids are similar to pigs in respect that fibrous feed components must pass through the stomach and small intestine before reaching the hindgut; the primary site of fibre fermentation. This study examines the VFI and apparent digestibility in vivo of two SBP based diets and determines their ability to meet the predicted energy and protein needs of mature ponies.Five mature Welsh-cross and three mature Shetland pony geldings with a mean liveweight (LW) of 219 kg (s.e.d. 2.2) were individually housed and offered 2 kg/d dry matter (DM) of a mature threshed grass hay (THAY), 60 g/h/d minerals and ad libitum access to either soaked molassed sugar beet pulp (MSBP) or soaked unmolassed sugar beet pulp (USBP).

Little information is available on digestion of the non-starch polysaccharide (NSP) fraction of fibrous feeds in equines. Two studies were conducted which examined the in vivo apparent digestibilities of proximate constituents and NSP in ponies offered diets based on botanically diverse fibrous foodstuffs.In study 1 (S1), three mature caecally-fistulated Welsh-cross pony geldings (266 kg LW) were used in a 3 x 3 latin square changeover design experiment consisting of three 21 day periods. Ponies were offered 4 kg dry matter (DM) per day of either unmolassed sugar beet pulp (USBP), hay cubes (HC) or a 2:1 mix of oat hulls:naked oats (OHNO) plus minerals in 2 equal meals per day. After completion of S1 the same 3 ponies were used in study 2 (S2) where they were offered 4 kg DM/day of a 50:50 mix of USBP:HC (USHC) plus minerals fed as in S1 for a 21 day period.

Although overall intake figures were high, critical levels (~400 g/kg DM) of unmolassed sugar beet pulp (USBP) inclusion suppressed dry matter intake (DMI) in ponies by up to 35% when included in complete pelleted diets made with dried grass (Hyslop, 2002). Dulphy et al (1997) have concluded that horses consume straw-based forages at lower levels than grass or legume-based forages. Given this observation with straw based diets, the objective of this study was to examine DMI, in vivo apparent digestibilities and nutritive values in ponies offered pelleted complete diets made from ground wheat straw and containing USBP at inclusion levels between 400 – 800 g/kg DM.

Previous work has indicated that unmolassed sugar beet pulp (USBP) may suppress voluntary feed intake (VFI) in ponies when offered as the major component; but not when offered as a relatively minor component of the diet (Hyslop et al, 1998, 1999). However, critical levels of USBP inclusion in equine diets remain to be established. This study examines VFI, in vivo apparent digestibilities and nutritive values in ponies offered pelleted complete diets containing USBP at inclusion levels between 0 – 800 g/kg dry matter (DM).

The Uk

De-hydrated forages are often fed to equids in the UK in place of more traditional grass hay, particularly where individual animals are known to have a sensitivity to dusty, mouldy hay which may play a part inducing respiratory problems such as chronic obstructive pulmonary disease (COPD). One such alternative forage is short-chop de-hydrated grass. However, there is very little information available on voluntary feed intake (VFI), apparent digestibility and nutrient intake parameters when de-hydrated grass is offered to equids compared with traditional grass hay. This study examines the VFI and apparent digestibility in vivo of a short-chop de-hydrated grass compared with a traditional grass hay and determines their ability to meet the predicted energy and protein needs of mature ponies.Six mature Welsh-cross pony geldings with a mean liveweight (LW) of 281 kg (s.e.d. 0.89) were individually housed and offered ad libitum access to either short-chop de-hydrated grass (DHG) or traditional grass hay (HAY) plus 60 g/h/d minerals. The DHG and HAY were made from the same 2nd cut perennial ryegrass sward cut on the same day.

Restricted Feed Intake

Many mature, non-pregnant, non-lactating equids are often kept in circumstances where they are expected to perform only light physical work or activity eg: a childs pony. Consequently their maintenance energy and protein needs can often be met at very restricted feed intake levels. Conversely, when they are housed during the winter months it is believed desirable to manage such animals on unrestricted ad libitum feeding regimes in order to allow the animals to exhibit their natural feed intake pattern and consume forage on a little and often basis throughout the daily feeding period. However, ad libitum access to the diet may lead to such animals becoming excessively fat. These conflicting needs of low energy and protein requirement coupled with the desirability of unrestricted access to the diet could both be met, at least in part, if a low quality forage is available ad libitum. This study examines the voluntary feed intake and apparent digestibility in vivo of a mature threshed grass hay offered ad libitum and determines its ability to meet the predicted energy and protein needs of mature ponies.

The Uk

There is increased interest in using forages other than grass hay as the basal diet for equines in the UK. Whilst a range of short-chopped dehydrated alfalfa based forages may be used as alternatives to grass hay in equine diets, there is very little information available on their likely intake characteristics, apparent digestibilities or their nutritive values. The objectives of the current experiment were:- 1) to determine the voluntary feed intake (VFI) characteristics of three alfalfa based forages when offered ad libitum to ponies, 2) to determine the in vivo apparent digestibility, digestible energy (DE) and digestible crude protein (DCP) contents of these forages and 3) to compare the actual energy and protein intakes with theoretical energy and protein requirements.

Internal Marker

The present study aimed to evaluate acid-insoluble ash (AIA) as an internal marker for the measurement the coefficient of total tract apparent digestibility (CTTAD) in rabbits through two experiments (E1 and E2). In E1, 48 rabbits were used to calculate the CTTAD of the same basal diet according to the European reference method (ERM), the AIA and the titanium dioxide (TiO2 with 1 g of TiO2/kg diet) techniques (n=16 rabbits/method). The effect of feed sample quantity on dietary AIA content was investigated and total collection of faeces was carried out to calculate marker recovery. In E2, 48 rabbits were allotted to three groups fed diets with no sugar beet pulp (SBP0) or with 100 (SBP100) and 200 (SBP200) g sugar beet pulp/kg (n=16 rabbits/group). Each group was divided into two subgroups, ERM and AIA (n=8 rabbits/subgroup), in which CTTAD was measured using the European reference and AIA method, respectively. In AIA subgroups, only 10% of the total daily faecal output was sampled from 9:00 to 9:30 am. Feed analysis in E1 showed that increasing sample quantity from 5 to 9 g did not affect the dietary AIA content; however, the analytical error was 7 and 5 times lower (P<0.05) for 9 g, when compared to 5 and 7 g samples. Feed analysis also showed 1.030±0.003 g TiO2/kg diet. Faecal marker recovery was 99.80±0.03 and 96.89±0.16% for AIA and TiO2, respectively. The CTTAD of dry matter (DM), did not differ between methods in E1, but a 5-fold higher variability (P<0.05) was observed for the TiO2 technique in comparison with the ERM and AIA methods. Also, no differences in the CTTAD of DM between the ERM and AIA methods were found in E2. In conclusion, AIA is a reliable internal marker in rabbits and offers the possibility of measuring the CTTAD of diets with precision, when complete faecal collection or feed intake measurement is not possible.

Digestive Processes

Estimates of digesta passage through specific segments of the alimentary tract are a vital component of modelling approaches which attempt to quantitatively partition digestive processes in equines. This study reports results from three studies where digesta passage of Chromium (Cr) mordanted feeds was determined in the caecum of ponies.Caecal outflow rates were determined during threein vivoapparent digestibility studies conducted using three caecally-fistulated ponies as described by Moore-Colyeret al, (1999) for studies 1 and 2; and McLeanet al, (1999) for study 3. Pony basal diets consisted of unmolassed sugar beet pulp (USBP), hay cubes (HC) or a 2:1 mix of oat hulls:naked oats (OHNO) in study 1; a 1:1 mix of USBP:HC (USHC) in study 2 and either 100% HC or one of 3 diets consisting of a 1:1 HC:barley mix where the barley was either rolled (RBHC), micronised (MBHC) or extruded (EBHC) in study 3.
