Fattening Pigs

In a co-ordinated experiment involving twenty centres and 558 pigs it was found that the growth rate, efficiency of food conversion and carcass quality of the pigs were not affected when one after-noon meal was omitted each week throughout the fattening period, provided the amount of meal thus saved was distributed between the remaining feeds during each week.Limited evidence is presented to show that similar results may be obtained when two afternoon feeds are omitted each week.

Fattening Pigs

A co-ordinated trial has been carried out at twenty-six centres to compare the effects of three practical rations on performance and carcass quality of fattening pigs. The simplest of these was the ‘Shinfield ration’ (SR) and this was compared with the more elaborate National Pig Progeny Testing Station rations, the ‘old’ ration (OPT) as used until January 1963 and the ‘new’ ration (NPT) as used since January 1963.The OPT ration was significantly worse than the SR and NPT rations in respect of growth rate and food conversion. The simpler and cheaper SR ration did not differ significantly from the NPT ration. Ration differences were not significant for any carcass measurements.

Once Daily

1. A co-ordinated trial has been carried out at 17 centres to compare the effects on performance and carcass quality of feeding growing pigs once or twice daily.2. No significant differences were found between growth rate, efficiency of food conversion or length of pigs on the two treatments.3. Killing out percentage was on average 0·92% worse for the pigs fed once daily, a significant effect, probably because the pigs on the two treatments received different amounts of food at the last feed before slaughter.

The aim of this study was to estimate the effect of feeding system on the growth rate and carcass quality of crossbred Improved Jezersko-Solčava x Texel (JSRT) lambs and to evaluate the effect of sex on these traits. The trial was conducted in nature according to the traditional rearing systems. The trial included 44 crossbred lambs, which were born and reared until the slaughter in three different flocks. In the age of 10 days suckled lambs were offered with ad libitum corresponding diets according to the feeding system. All lambs were slaughtered in seven consecutive days by the same procedure. The effect of feeding system significantly affected daily gain from birth to slaughter, EUROP carcass conformation and shoulder width. Likewise, the effect of sex significantly affected daily gain from birth to slaughter and internal fatness of carcasses. According to carcass cuts the feeding system significantly affected only the proportion of neck and leg. Considering meat quality traits, feeding system had a significant effect on the pH 45 and CIE a* values. In this study, we could speculate that more than the feeding system the growth and the carcass traits as well as meat traits were affected by the amount of the supplement.

Effect On Growth

The effects of sex and age of castration of males on growth rate, feed efficiency and carcass characteristics in bacon type swine were measured using 16 pigs each as gilts, entire boars, and boars castrated at birth, 6, 12, 16, and 20 weeks of age. Castration at 20 weeks was too late since some pigs reached 200 pounds live weight before that age. Boars consumed less feed daily than barrows and gilts, were thinner in loin fat, and yielded a higher percentage of shoulder than gilts. The carcasses of boars and gilts were longer, had less fat covering over the shoulder and back, a larger area of loin, and a higher iodine number than those castrated late. Acceptability tests showed that sex or age of castration did not affect the flavour, odour, or tenderness of the meat.Purebred breeders can delay castration for better selection of boars without any serious effect on growth, physical carcass characteristics, and feed requirements. Although the market discriminates against boars, it appears questionable whether castration is necessary when boars are slaughtered at 200 pounds before they reach the age of 150 days.

1. At two centres, Hillsborough and Shinfield, forty-eight pigs in four groups were fattened on rations containing Australian sorghum. The control ration consisted of 30%, wheatfeed, 30% barley meal, 30% maize meal and 10% fish meal. In the three experimental rations either barley meal or maize meal or both were replaced by sorghum.2. The rations containing 30% of sorghum proved to be equal to the control ration as far as live-weight gain of the pigs and the efficiency with which they utilized food was concerned. When 60% of the ration consisted of sorghum there were indications that both rate of gain and food utilization suffered.3. Some aspects of carcass quality suffered when either sorghum alone or sorghum plus maize formed 60% of the ration. The quality of the control carcasses, although quite good by present-day standards, would not qualify for first grade when commercial grading is re-introduced.4. Bacon produced on rations containing up to 60% sorghum had no off-taste or unpleasant flavour.5. In general, the value of sorghum in the ration of fattening pigs was found to be about equal to that of maize.

SUMMARYA by-product of the distilling industry designated ‘distillers’ grains plus solubles' was evaluated using forty-eight growing pigs. The product was included at 0, 14·7 and 25% in three diets in which the proportion of other constituents was adjusted to give similar concentrations of TDN, dry matter and crude protein.The performance and carcass quality of pigs receiving 0% and 14·7% of the by-product in the diet was similar, but inclusion at 25% significantly reduced growth rate (g/day) from 632 for the 0% diet to 578.

We have been witnesses to import of numerous premixes produced by various producers and of different quality in regard to concentration of ingredients which are their main components. In our previous studies (Zivkovic et al., 2010) we obtained results confirming that in use of domestic premix more economically efficient production is realized in nutrition of sows and piglets, so this research was carried out with objective to verify the effects of several different imported premixes and those produced according to domestic concept, in nutrition of growing-fattening pigs. Research was performed on private farm in the vicinity of Sabac in Serbia. Nutrition of fattening pigs using mixture which contained adequate premix of domestic production improved the growth rate by 7.6% without any significant difference in food conversion. Cost of feed when domestic premixes were used in nutrition of fattening pigs was by 4.1% lower and value of realized pigs by approx. 4.51% more favourable when domestic premixes were used in nutrition of investigated animals. Dressing percentage of pigs on domestic premixes was higher by 2.0%, and there was no difference in meatiness between compared groups of animals in the experiment. In general, obtained results showed that use of both types of compared premixes can be recommended, but it is more economically efficient to use domestic premixes in nutrition of fattening pigs.

Abstract Nephrops was found to be of low quality as food for cod. In a laboratory experiment the mean specific growth rate of 1 kg cod was 0.184 and 0.415% d−1 when fed to satiation on Nephrops and capelin, respectively. This large difference in growth rate resulted not only from less intake of Nephrops (1.19 kg cod−1) than capelin (1.55 kg cod−1) but also because more Nephrops (4.6 kg) than capelin (2.2 kg) were required to produce each kilogramme of cod. Higher food conversion ratio was consistent with lower fat content of Nephrops (1.3%) than capelin (9.2%) but the exoskeleton also reduced the digestion rate of Nephrops. In the groups where Nephrops and capelin of equal mean weight were offered simultaneously, 40% of the diet consisted of Nephrops during the first week and 10% during the final seven weeks of the experiment. At the end of the experiment, condition factor, liver index, and gonadosomatic index were significantly lower for cod fed on Nephrops (0.967, 5.7, 7.1, respectively) than for those fed on capelin (1.086, 15.8, 11.2, respectively). These results suggests that predation by cod on Nephrops might be reduced by regular release of capelin or other similar food in the distributional areas of Nephrops.
