In vivo apparent digestibility of proximate constituents and non-starch polysaccharides in ponies offered botanically diverse fibre based diets

There is increased interest in using sugar beet pulp (SBP) products as forage replacers in equine diets. Previous work (Hyslop et al 1998) has indicated that SBP products may suppress voluntary feed intake (VFI) in ponies when they are the major fibre source at between 550-700 g/kg total diet dry matter (DM). This study examines VFI and apparent digestibility in vivo where soaked unmolassed sugar beet pulp (USBP) was offered as a partial forage replacement to ponies receiving ad libitum grass hay.Four mature Welsh-cross pony geldings (280 kg LW s.e. 6.6) were individually housed and offered 0.86 kg/d of micronised barley (MB) and given ad libitum access to grass hay (HAY). In addition, ponies were offered either 0, 1, 2, or 3 kg/d USBP (U0, U1, U2 and U3 respectively) according to a 4 x 4 latin square changeover experimental design.

Processed cereals are used routinely in diets for equines but little information is available on how physical processing affects the digestibility of cereals in equines. This study examines the effects of three physical processing methods (rolling, micronisation and extrusion) on the in vivo apparent digestibility of barley fed to ponies.Three mature caecally-fistulated Welsh-cross pony geldings, (LW 284kg ± 3.8kg) were used in a 3 x 4 incomplete latin square changeover design experiment consisting of four 21 day periods. Each period comprised a sixteen day adaptation phase and a five day recording phase when apparent digestibility in vivo was determined. Ponies were offered 4kg dry matter (DM) per day of either 100% hay cubes (HC) or one of three diets consisting of a 50:50 barley:hay cubes mix. The barley in the mixed diets was either rolled barley (RB), micronised barley (MB) or extruded barley (EB). Diets were offered in 2 equal meals per day fed at 09:00 and 17:00 hours respectively.

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.

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.

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).

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.

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).

SummaryFour Ayrshire cows in their second lactation were used in a 4×4 Latin square experiment to determine the effects of frequency of feeding on milk secretion. The animals were given a diet consisting of hay, sugar-beet pulp and dairy concentrates (34·9:19·7:45·5 on a dry-matter basis) either in 2 equal meals/d at 07.00 and 17.00 h or with the hay in 4 meals at 07.00, 12.00, 17.00 and 22.00 h and the sugar-beet pulp and concentrates in 24-h meals. Each feeding frequency was tested at 2 levels of feeding providing either 100 or 80% of the standard requirements for energy.There were no significant effects of frequency of feeding on milk yield or on the milk content of fat, protein, lactose, solids-not-fat or total solids, but underfeeding depressed the yield of milk and of all milk constituents. Neither the frequency nor level of feeding had appreciable effects on the fatty-acid composition of the milk fat or on the blood glucose concentration, but in animals fed frequently plasma urea levels were lower than in animals fed twice daily and there was no postprandial peak in urea concentration.
