Pea-wheat bi-crop silages were reported to have moderate nutritive value when the proportion of peas in the sward was less than 200 g/kg (Adesoganet al., 1999). These authors also suggested that improvements in the digestibility, intake and nitrogen (N) balance of the forages may result from increasing the proportion of peas in the sward. This experiment was designed to examine this theory by determining thein vivoapparent digestibility, N retention and voluntary feed intake (VFI) in sheep of pea-wheat bi-crop silages containing different ratios of peas to wheat and harvested at two stages of growth.

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.

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.

Two Stages

SUMMARYThe nutritive value and yield of forage legumes and barley harvested as immature herbage, hay and straw were measured in two experiments. The voluntary feed intake of peas at all stages of maturity and immature herbage from woollypod vetch was substantially lower than that of common vetch and chickling. At each stage of maturity barley was less digestible than all the forages except immature peas. Despite exceptionally cold weather in February/March 1985, yields of common vetch were higher in 1984/85 than in 1985/86 when there was less rain. Peas yielded the most hay, and chickling yielded less seed and straw than common vetch, peas and barley. Yields of digestible dry matter from straw and seed exceeded those from hay but protein yield at the two stages was similar. Mechanical baling substantially reduced the yields of baled hay but these losses would be reduced to less than 10% if the residues were grazed.

Volumes Of Distribution

Three sheep with permanent fistulas of the rumen were each given dried grass and two hays, each in three different amounts, and the apparent digesti-bility of the roughages in the rumen and distal to the rumen was determined. A lignin ratio method was used to measure digestibility.With increase in the amount of the poorest hay given, the proportion digested in the rumen fell and that distal to the rumen increased. With the second hay this effect was also noted but was not statistically significant. The voluntary intakes ofdry matter varied from 1·94 kg/day for the dried grass to 1·28 for the poorest hay. The volumes of distribution of polyethylene glycol in the rumen when feed was offered ad libitum, however, were the same, irrespective of the type of feed, at between 14·1 and 15·2 litres. These observations were confirmed at slaughter. The results support the hypothesis that sheep voluntarily consume roughages of different qualities to achieve constant fill of their rumens, and that little regulation of voluntary intake can be attributed to distension of the hind gut.

To determine morphological and molecular characteristics of porcine mammary tissue in vivo, mammary tissue was collected from 18 sows at 3 to 6 d of lactation and 17 to 19 d of lactation using a biopsy technique. The success of the technique was determined by monitoring lactation performance, as evidenced by sow rectal temperature, voluntary feed intake, milk somatic cell count, and piglet average daily gain. Up to 1.7 g of mammary tissue was collected at each biopsy without decreasing sow feed intake or piglet growth. Key words: Biopsy, mammary gland, lactation, sow

Nutrients Digestibility

Pomegranate by-products (peel and seed) contain about 40-45 percent of the fruit’s weight, but little information is available on their nutritive value. Chemical analysis of the pomegranate seed (PS) show that it contains average of 10-12 percent of crude protein. PS also contain a little amount of tannin (about 2.7 percent). Since feed accounts for 75-85% of the total costs of meet production and the use of them in feeding ruminant may decrease the cost of feeding. The objective of this experiment was also to determine nutrients digestibility of PS.

Insulin-like growth factor-1 (IGF-1) stimulates many anabolic processes within the body. In entire animals, release of IGF-1 has been shown to be regulated by nutritional status (e.g. starvation/re-feeding) and in reproductive tissues by gonadotropins and steroid hormones (Phillips et al., 1990). To investigate this further the relation between serum IGF-1 and N retention has been studied in entire and castrated pigs at different planes of nutrition and stages of growth.

The present study was carried out to ascertain the effect of dietary inclusion of a customised supplement to farmers’ based diet on voluntary feed intake and nutrient metabolism in crossbred calves. In order to carry out the experiment, fifteen crossbred calves (18 months old; 166.53±4.93 kg mean BW) were randomly allocated to 3 groups (5 calves in each group) as CON, Treat and SBR, in a CRD for 30 days. The calves in CON (control) group were fed on cereal straw based diet with concentrate mixture as per the farmers’ practices, whereas, the calves in Treat were fed according to CON with additional customized supplement @ 0.25% of BW. The calves in SBR group were fed standard diet as per Kearl (1982). The intake (gd-1) of DM and OM was significantly Pandlt;0.01 higher in SBR than Treat and CON groups, while DM and OM intake as % of BW in Treat group has an intermediate position between SBR and CON groups. The concentrate intake (gd-1) was significantly Pandlt;0.001 higher in SBR followed by Treat and CON group, respectively. However, intake of wheat straw and green maize was found to be identical Pandlt;0.05 among all the groups. The digestibility coefficient of DM, OM, CP, NDF and ADF was significantly Pandlt;0.05)higher in Treat and SBR groups than CON. The N-retention as per cent of intake and absorbed-N was significantly Pandlt;0.001 higher in Treat and SBR groups than CON. The Ca and P retention gd-1 was significantly Pandlt;0.001 higher in SBR group followed by Treat and CON groups. The intake gd-1 and density % of DCP and TDN were significantly Pandlt;0.001 higher in SBR group followed by Treat and CON groups. Thus, it can be concluded that supplementation of the customised supplement (@ 0.25% of BW) to CON diet significantly improved the voluntary feed intake and nutrient metabolism in crossbred calves.
