Voluntary Food Intake

Immediately following weaning, voluntary food intake in the young pig is low and very variable. This can lead to reduced digestive efficiency and poor physical performance. One approach to try to stimulate intake is to manipulate the physical form of the diet. Previously it has been shown that, contrary to popular belief, young pigs are very adaptable with regards to diet presentation and in particular with respect to pellet size(Edge et al., 2000). Pigs from 10 to 56 days of age would consume a 5.0mm pellet as readily as a 1.8mm pellet with no adverse effects on production variables.

Performance Research

The provision of creep feed to suckling pigs is considered to stimulate early food intake as well as health post weaning. However, Barnett et al. (1989) found no effects of creep feeding on post-weaning performance. Research by Pajor et al. (1986) indicated that there is a high variability in creep feed intake both among and within litters. This variability in creep feed intake is probably the main cause of disagreement on the effects of creep feed provision. The objective of the present study was to assess the effect of creep feed consumption on individual food intake characteristics and performance of group-housed weaned pigs. Chromic oxide was added to the creep feed to identify piglets that consumed food during the suckling period. In the piggery, IVOG®-feeding stations were used to measure individual food intake after weaning.

Using Data

Food intake (FI) can be predicted on the basis of variables that describe food quality and the animal. Live weight (LW) is usually the only variable that is used to describe the animal. Animal fatness, as estimated by condition score (CS), can affect FI at a given LW. Body lipid produces signals (leptin) that affect energy intake and energy expenditure. If fatness acts on intake via its effect on energy expenditure, the effects of body lipid content on food intake can be incorporated into an existing intake model. Our objectives were to construct and test models that predict effects of fatness on intake and performance, using data obtained with ewe lambs to parameterise and test the models.

The Relationship

1. Two experiments concerned with the voluntary intake of food by artificially reared lambs are described and the results discussed.2. When the diets were pelleted the addition of finely ground oat husks to form as much as 40% of the diet had practically no effect on live weight gain since the lambs controlled their consumption to achieve the same energy intake on the various diets. When the diets were given as a meal, the addition of 20% oat husks caused food intake to increase, digestible dry-matter intake to remain the same and growth rate to be somewhat poorer; but the addition of 40% oat husks caused no further increase in intake so that digestible drymatter intake fell markedly and growth rate was much reduced. It is argued that the relationship between food intake and digestibility is dependent on the physical form of the diet.3. Addition of beef tallow to the meal diets had very little effect on the lambs' performance.4. Lambs which had received a restricted quantity of milk replacer from birth to 11·4 kg live weight had a slower growth rate and poorer food conversion efficiency during the subsequent feeding period (13·6–34·1 kg) than lambs which had received milk ad libitum. This effect was greater with meal diets containing 40% oat husks than with more concentrated diets.5. On a pelleted diet containing 85% barley a conversion ratio of 3·21 was achieved over the whole fattening period, indicating the commercial feasibility of intensive lamb production on cereal diets.

And Performance

The aims of the present study were to investigate (1), the potential anthelmintic properties and (2), the nutritional consequences of commercially available condensed tannins on parasitised sheep fed,ad libitum, either a high- or a low-protein food. For this purpose, forty-eight previously parasite-naïve sheep (n12) were infected with 2000Trichostrongylus colubriformislarvae/d for a 67-d experimental period. Two experimental foods were made: a low (L), formulated to be inadequate in meeting the requirements of growing sheep for metabolisable protein (MP), and based on wheat, citrus pulp, and oatfeed; a high (H), expected to be above the requirements of growing sheep for MP, based on similar ingredients but supplemented with protected soyabean meal. Two additional foods were made by adding 60 gQuebracho(a condensed tannins (CT) extract)/kg fresh matter to foods L and H (foods LQ and HQ respectively). This level ofQuebrachosupplementation has been previously shown to reduce the level of parasitism in restrictedly fed, parasitised sheep. The experiment was divided into two periods: period 1 (P1, day 1–38) and period 2 (P2, day 39–67), each one associated with different phases of an intestinal parasitic infection. Six sheep from each group were slaughtered at the end of P1, and the remaining sheep were slaughtered at the end of P2(day 67). Although faecal egg counts (FEC; number of parasite eggs/g faeces) and total egg output were reduced in sheep offered the supplemented foods during P1(P<0·05), worm burdens on day 38 were unaltered. NeitherQuebrachosupplementation nor food protein content during P2affected FEC and worm burdens. Food intake and performance were higher in sheep offered food HQ compared with sheep offered food H (P<0·05); no differences were observed in sheep offered foods LQ and L throughout the experiment. The previously shown anthelmintic properties of CT were not observed followingad libitumintake of either low- or high-protein foods supplemented withQuebrachoextract. Higher levels of CT supplementation may be required to reduce parasitism and consequently improve the performance of parasitised sheep, when fedad libitum. Supplementation with CT conferred advantages on the performance of parasitised sheep on a high- but not on a low-protein food.
