Sibling Groups

Weaning is a stressful period for the piglet, invariably typified by low voluntary feed intake and reduced performance. Moreover, if siblings are separated and mixed with other litters, stress increases and the learned stimulus of the group to feed is disturbed (Brooks et al., 2003). This experiment was part of a larger investigation into the voluntary feed intake of the piglet in the immediate post weaning period. We investigated the difference between mixed litter origin or sibling groups on latency to initiate feeding and performance to day six post weaning. We hypothesised that mixing litters would increase latency to first feeding and reduce growth rate in the first few days after weaning.

1. Voluntary feed intake, performance and carcass quality were studied with 20 individually housed pigs given isocaloric diets (2,770 kcal/kg. DM) containing either 8·9 % or 12·9 % crude fibre in the dry matter over the period of growth from 45 to 91 kg. live-weight.2. There were no significant differences between diets in voluntary feed intake, rate of gain or carcass quality.3. Apparent digestibility coefficients and rates of passage of the diets were determined in eight castrated male pigs. Rates of passage were not significantly affected by diet or live-weight when determined at 57 and 82 kg. live-weight.

Weaning Piglets

At weaning, piglets must adapt to considerable changes in their environmental, immunological, and nutritional status. This period of adaptation is accompanied by a reduction in piglet growth rate that has been associated with the shift from sow’s milk to a solid dry diet. Consequently, feeding management strategies that result in increased feed intake may increase piglet growth rate postweaning. This study evaluated the effects of providing feed as a gruel and feeding on floor mats on piglet performance for three weeks after weaning

A study was conducted to determine the growth performance and carcass characteristics of indigenous Venda chickens fed a grower’s diet supplemented with varying levels of garlic meal. The study was based on four diets containing similar energy but different garlic meal supplementation levels of 0, 10, 15 and 25 g/kg DM. At 50 to 91 days, all the growth and carcass parameters measured were improved (P less than 0.05) by garlic meal supplementation. Feed intake, growth rate, feed conversion ratio, live weight, carcass weight, dressing percent, breast meat, thigh, drumstick, gizzard and fat pad weights of Venda chickens were optimized at different garlic meal supplementation levels of 14.7, 15.8, 8.0, 16.4, 14.2, 12.7, 11.2, 12.7, 8.2, 10.5 and 15.1, respectively. These findings have implications on ration formulation for indigenous Venda chickens. Thus, it was concluded that garlic meal supplementation improved feed intake, growth rate, live weight and carcass weight of Venda chickens.

The present study investigated the effect of meals and fractions of black soldier fly larvae (BSFL; Hermetia illucens) in diets for Atlantic salmon (Salmo salar) on the physical quality of feed pellets, nutrient utilisation, and growth performance. Six extruded diets were produced: control diet (CD); full-fat BSFL meal diet (IM); defatted BSFL meal diet (DFIM); de-chitinised BSFL meal diet (DCIM); BSFL oil diet (IO) and BSFL exoskeleton diet (EX). The full-fat, defatted and de-chitinised meals replaced 15% of protein in the control diet. An eight-week study was conducted using salmon with average 28 g initial weight. The full-fat and de-chitinised meals in the diets numerically reduced pellet hardness, expansion, and water stability. The full-fat and de-chitinised meals improved growth rate of salmon, whilst defatted meal, oil and exoskeleton supported similar growth performance as the control. Feed intake and growth rate of fish fed full-fat meal diet were higher than those fed the other insect diets, but defatted meal gave a better feed conversion ratio than full-fat meal. Defatted meal, de-chitinised meal and exoskeleton reduced protein digestibility in fish, however; defatted meal increased the digested protein retention. In conclusion, use of full-fat BSFL meal improved feed intake and growth rate of salmon when replacing 15% of dietary protein. The present results suggest that less processed fullfat form of BSFL is more optimal in diets for salmon and further processing to remove lipid or exoskeleton fractions would only lead to an additional cost.

Selection For

There have been a number of reports that voluntary feed intake (VFI) of modern pig genotypes may be the limitation to their growth performance. It has been suggested that selection for leanness (Fowler et al. 1976) and breeding for faster growth may have reduced appetite.In addition there is only limited information about the effect on VFI, performance and carcass characteristics of pigs fed ad libitum to liveweights greater than 100kg. A study was therefore undertaken to compare VFI and energy intake of improved genotypes with predicted intakes based on earlier genotypes (ARC, 1981). The associated effects on performance and carcass characteristics at heavier slaughter weights were also studied.

Considerable Body

There is a considerable body of information on the voluntary feed intake of pigs fed on dry diets. However, there is a paucity of information on the factors affecting feed intake of pigs fed liquid diets. Pigs have a limit to their volumetric intake and will normally maximise dry matter intake when fed dry diets, ad libitum. For pigs fed dry feed the requirement for water per unit of dry matter will be dependent upon the composition of the feed and the requirement for renal clearance of nitrogen and minerals. What is not clear, is whether presenting the feed mixed with water results in excessive water intake that produces a point loading of the stomach, which in turn limits voluntary feed intake, i.e. whether physical bulk limitations override the normal homeostatic control. Therefore, it is not possible to extrapolate from data generated with dry fed pigs and anticipate voluntary intake of pigs fed dilute liquid diets. The aim of this study was to determine the effect of dry matter concentration of liquid feed on feed intake and growth performance of grower-finisher pigs.

Ad Libitum

In a recent experiment using the same improved genotype, pigs over the liveweight range 25 to 120 kg were found to have modest voluntary energy intakes (Chadd and Cole, 1988) particularly when compared with former intake prediction equations. It follows that the response of such pigs in terms of voluntary feed intake behaviour when provided with diets differing in energy concentration may have also changed. Diets that are formulated to be low in energy density and therefore bulky in nature are likely to represent more of a limitation to voluntary feed intake than previously. Former experiments designed to examine the pig's ability to adjust feed intake in order to maintain a constant energy intake have produced results varying from complete to incomplete compensation.A study was undertaken to examine the response of a modern genotype in terms of voluntary feed intake, digestible energy (DE) intake, growth performance and associated carcass characteristics, when offered a range of dietary energy concentrations ad libitum and taken to a heavy slaughter weight.
