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.

Effect On Growth

1. Results are reported of an experiment with fattening pigs carried out under commercial conditions, to obtain further information on the comparison of all-meal feeding with meal plus unrestricted amounts of whey. In addition, the effect of omitting the antibiotic, oxytetracycline, from the diet during the latter half of the fattening period was investigated.2. There were four treatments. (i) Meal only ad lib. up to a daily maximum of 6 lb./pig, with oxytetracycline included in the diet for the whole fattening period. (ii) As (i) but oxytetracycline included in the diet only up to an average pen live weight of 130 lb. (iii) 3 lb. meal reduced to 2 lb./pig/day by 13 weeks of age plus unrestricted amounts of whey with oxytetracycline included in the basal meal for the whole fattening period. (iv) As (iii) but oxytetracycline included in the diet only up to an average pen live weight of 130 lb.There were five pens of nine group-fed pigs on each treatment, involving a total of 180 pigs. The pigs were on experiment from approximately 8 weeks of age to bacon weight. Comprehensive carcass measurements were made on all pigs.3. The meal plus whey-fed pigs grew significantly slower and utilized their food significantly less efficiently than those fed meal only. They also had a significantly lower dressing percentage, but longer and less fat carcasses than the all-meal fed animals. The results are discussed in relation to those obtained in earlier experiments completed under similar conditions at the Cow and Gate farm.4. Comparison of the efficiency of food utilization results of the all-meal and meal plus whey-fed pigs showed that 1 gal. of whey replaced approximately 0·7 lb. of meal.5. The results showed that omission of antibiotic from the diet of either the all-meal or meal plus whey-fed pigs after they reached 130 lb. live weight, had no significant effect on growth rate, efficiency of food utilization or any carcass measurements of the pigs.We wish to thank the Director of Messrs C. and G. Prideaux, Ltd., Bacon Curers, Motcombe, Shaftesbury, Dorset, for permission to take carcass measurements of the experimental pigs, and we are greatly indebted to Messrs K. Lawrence and P. Prideaux who most conscientiously took these measurements.

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.

ABSTRACT Wastewater from the tanning industry of UPTD XX has entered the waters of Batang Anai River, West Sumatra. This wastewater quality exceeds the established quality standards and can be harmful to tilapia as a river biota. This study aimed to analyze the effect of sublethal tannery wastewater on food conversion ratio (FCR) and the specific growth rate (SGR) of tilapia. This study was conducted in three conditions: zero wastewater exposure (control), 1.85%, and 3.69% wastewater exposure. Each situation was set in triplo and observed for 28 days. We analyzed the correlation between duration exposure to the FCR and SGR by using regression and correlation analysis. Results showed an increase in the FCR value during observation in both wastewater exposure variations of 1.85% and 3.69%, with FCR values consecutively 1.19 and 1.75. At the same time, the control experiment showed a decreasing value of FCR. On the contrary, SGR values were decreased during observation in both wastewater exposure variations of 1.85% and 3.69%, consecutively 3.09% and 3.72%. While increasing SGR value was observed in the control experiment. A reliable correlation was obtained between the FCR and SGR ratio of tilapia to the exposure duration (r = 0.99). Furthermore, multivariate analysis showed a significant difference between the FCR and SGR to the variation and period of direction. It can be concluded that the longer the exposure time and the higher the concentration of exposure, decreasing the food uptake of tilapia and reducing the specific growth rate. Keywords: tilapia, ratio growth rate, tannery wastewater, feed conversion, West Sumatra   ABSTRAK Limbah cair dari industri penyamakan UPTD XX, Sumatera Barat telah memasuki perairan Sungai Batang Anai, Sumatra Barat. Kualitas air limbah ini melebihi standar kualitas yang ditetapkan dan dapat berbahaya bagi nila sebagai salah satu biota sungai. Penelitian ini bertujuan untuk menganalisis pengaruh air limbah penyamakan kulit terhadap Rasio Konversi Pakan (Food Conversion Ratio/FCR) dan Laju Pertumbuhan Spesifik (Specific Growth Rate/SGR) pada ikan nila. Penelitian ini dilakukan dalam tiga variasi, yakni tanpa paparan air limbah (uji kontrol), paparan air limbah 1,85% dan 3,69%. Setiap variasi dilakukan secara triplo dan diamati selama 28 hari. Korelasi antara lama paparan dengan rasio FCR serta SGR, dianalisis dengan menggunakan regresi dan analisis korelasi. Selanjutnya analisis multivariat menggunakan ANOVA two-way untuk melihat perbedaan signifikan FCR dan SGR terhadap variasi dan durasi paparan. Hasil penelitian menunjukkan peningkatan nilai FCR di kedua variasi paparan air limbah 1,85% dan 3,69% dengan nilai FCR berturut-turut 1,19 dan 1,75. FCR dalam uji kontrol menunjukkan penurunan nilai FCR. Sebaliknya, nilai SGR cenderung menurun selama pengamatan pada kedua variasi paparan air limbah 1,85% dan 3,69%, dengan nilai SGR berturut-turut 3,09% dan 3,72%, sementara peningkatan nilai SGR terjadi pada uji kontrol. korelasi yang sangat kuat diperoleh dari nilai FCR dan SGR terhadap durasi paparan (r = 0,99). Selanjutnya, uji signifikansi ANOVA menunjukkan perbedaan yang signifikan antara rasio FCR dan SGR dengan variasi dan durasi paparan air limbah. Dapat disimpulkan bahwa semakin lama waktu paparan dan semakin tinggi konsentrasi paparan air limbah, mengurangi serapan pakan ikan nila dan mengurangi tingkat pertumbuhan.

Different Levels

1. Results are reported of an experiment carried out under commercial conditions to obtain information on the effect of four different levels of allmeal feeding on the performance and carcass grading results of fattening pigs.2. There were four treatments. All pigs were given the same meal mixtures and were fed dry and ad lib. up to four different daily maximums, namely, 6½, 6, 5½ and 5 lb. meal/pig/day. There were five pens of nine group-fed pigs on each treatment, involving a total of 180 pigs. The pigs were on experiment from approximately 8 weeks of age to bacon weight. Comprehensive carcass measurements were made on all pigs.3. The results showed that as the level of feeding was decreased, the growth rate of the pigs, back fat thickness and belly thickness were reduced, and the depth and breadth of eye muscle were increased, while the efficiency of food utilization, carcass dressing percentage and carcass length were not markedly affected. Commercial grading results similarly improved as the level of feeding was reduced.4. It was concluded that under the conditions prevailing, the maximum daily meal allowance should be of the order of 5½ lb./pig in order to obtain relatively satisfactory carcass grading.5. Subdivision of the carcass measurement and commercial grading data according to sex of pig showed that in general at each level of feeding the carcasses of the female pigs were superior to those of the male animals.The possibilities of segregating pigs according to sex during fattening as a means whereby undue retardation in the growth rate of the females might be prevented without adversely affecting their carcass grading, was discussed.

In the last ten years 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. There is relatively few data on the effects of their nutritive value in pigs, 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 sows, suckling piglets and weaned piglets. Research was performed on private farm in the vicinity of Sabac in Serbia. Obtained results showed that there was no significant difference in losses of body masses and food consumption in sows during lactation period. Nutrition of suckling piglets using mixture which contained adequate premix of domestic production improved the growth rate by 7.6%. Cost of food when domestic premixes were used in nutrition of sows and piglets was by 5.3% lower, and value of realized piglets by approx. 26.0% more favourable when domestic premixes were used in nutrition of sows and suckling piglets. Piglets in rearing were fed mixtures containing imported premixes showed no significantly important effect on gain, but had poorer feed conversion by 6.2% compared to animals fed diets containing domestic premix. Domestic premix in mixtures reduced the cost of mixtures by 3.4% and reduced the cost of gain of piglets in rearing by 9.9% compared to nutrition with diets containing imported premixes. In general, obtained results shoed that use of both types of compared premixes can be recommended, but it is more economically efficient to use domestic premixes in nutrition of sows and piglets.

AT the 1935 meeting of the New Zealand Grassland Associalion McMeekan read a paper on the nutritive 'value of pastures in pigraising, and, in respect to fattening pigs, stated that grass " is not capable of materially reducing the total requirements of other food except under a low plane of feeding, the successful practice of which is dependent on economic considerations " : he gave details of two feeding trials which showed that " no measurable amount of nutriment was derived from pasture by the pigs in these trials, no significant difference either in growth-rate or in economy of foodconsumption being apparent."

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.

ABSTRACTIndividual and group-penning, and entire male and female sexes were investigated in a factorial design. The size of group was five pigs. The diets were given to a scale based on live weight.Individual penning gave significantly faster gains than group penning (679 v. 653 g/day, P < 0·01) but the improvement in food conversion ratio was not significant. Loin sample joints from individually-penned pigs had less lean and significantly more fat than did those from group-penned pigs. The faster growth rate and greater fatness of the individually-penned pigs indicated that more energy was retained by these animals and it was concluded that the greater retention of energy derived primarily from an apparently reduced metabolic heat production. The associated increase in initial growth rate was accentuated by the nature of the feeding scale.There was some indication that boars did not grow as well as gilts in individual pens. Boars grew faster than gilts and converted food more efficiently to live-weight gain especially above 50 kg. They had lower killing-out yields and less fat than gilts.

Crossbred Pigs

The performance of 160 crossbred pigs on a commercial piggery was studied from weaning, at an average age of 20 days, to slaughter at 27 weeks. They were fed control diets (treatment 1) or similar diets containing the growth promotants tylosin + sulphadimidine, virginiamycin + sulphadimidine + furazolidone, and carbadox + oleandomycin, (treatments 2, 3 and 4), according to regimes recommended by the 3 manufacturers. During the starter phase (3 to 11 weeks) pigs in treatments 2 and 3 (P < 0.01) and treatment 4 (P < 0.05) grew faster than the controls. Growth on treatment 3 was faster than that on treatment 4 (P < 0.05). Food conversion ratios did not differ. Growth rate and food conversion ratio on all treatments were similar during the grower phase (11 to 27 weeks). Overall, the growth rate, food conversion ratio, cold dressed weight, carcase dressing percentage and depth of fat over the eye muscle did not differ significantly between treatments. It is concluded that the growth promotants tested failed to improve overall growth rate and food conversion.

Growth rate and carcase characteristics were compared for Friesian bulls and steers fed solely on pasture and set stocked at 4.9 animals ha-1 Over a period of 11 3 weeks the animals achieved a mean liveweight gain of 0.5 kg animal-1 day-1. At this level of nutrition no significant difference in the growth rates of the bulls and steers was evident. However, the bulls had a higher dressing percentage (3.4 per cent), a higher percentage yield of meat (5.5 per cent), a lower percentage yield of trim (2.3 per cent), a lower percentage yield of bone (3.1 per cent), a larger eye muscle area (4.9 cm2), a greater carcase weight (1 7 kg), and a greater weight of saleable meat (24.1 kg). The steers had a higher percentage of total carcase in the hindquarter (3.6 per cent).
