Dietary Oil

Oil supplementation of by-product based diets is a common method of increasing the energy content of pig diets to levels equivalent to those of cereal-based diets (Overland et al 1999). However, by-product based diets supplemented with oil have been reported to reduce feed intake and digestible energy intake when compared with cereal-based diets (Magowan et al 2004). It is not known whether this effect occurs as a result of the higher levels of fibre in by-product-based diets or as a result of a reduction in palatability arising from the inclusion of oil in the pellet. The aim of this experiment was to investigate the effect of method of vegetable oil blend application (either incorporated directly into the pellet (IN), or sprayed on after pelleting (SP)) on the performance and carcass characteristics of commercially housed finishing pigs.

Oil Blend

By-product-based diets generally contain lower levels of energy than cereal-based diets due to higher levels of fibre (Bakker et al., 1995). Supplementation with oil is a common method of improving the digestible energy content of by-product-based diets and it has been reported that this practice may also improve energy digestibility. However, the results of McCann et al., (2004) suggested that the method of oil application to finishing pig diets may affect the digestibility of dietary nutrients. The aim of this experiment was to compare apparent digestibility coefficients determined in finishing pigs offered either by-product based diets or cereal-based diets, with and without vegetable oil blend supplementation applied using two different methods (either directly incorporated into the pellet (IN) or sprayed (SP) on after pelleting).

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

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.

Dietary Treatments

The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

Data for a total of approximately 1100 lambs tested in 12 trials from 1992 to 1995 in commercial lamb test stations in Quebec were used to determine the effect of sex, sire breed and genetic type on growth performance and carcass characteristics. Lambs were housed two to a pen and fed commercial diets. Maximum test length was 112 d. Lambs were slaughtered when their liveweight was approximately 47 ± 5 kg for the males and 43 ± 4 kg for the females. Feed intake and growth rate were measured during the test, and carcass measurements were taken at slaughter and at 24 h following slaughter. Feed intake was the average for the pen, while the growth and carcass measurements were taken individually. Males ate more per day, had better gain and were younger at slaughter than females. Females had more body fat and better carcass conformation scores than males. However, males did not have a greater loin muscle thickness compared to females. Lambs sired by Hampshire or Suffolk rams had superior growth performance and leaner carcasses than lambs sired by Dorset rams. However, Hampshire and Suffolk-sired lambs did not have a greater loin muscle thickness compared to Dorset-sired lambs. Analysis of different genetic types did not demonstrate a pronounced effect on lamb performance. No specific genetic composition was clearly superior to the others for the various variables studied. Genetic quality within a breed of sheep bought or kept for reproduction is as important as the choice of breed or the combination of breeds. Key words: Lamb, growth performance, carcass composition
