Seed Yields

One-hectare plots of two-row (Fairfield, Fergus and Klages) and six-row (Bonanza, Klondike and Peguis) barley cultivars were seeded on fallow. Seed yields, kg dry matter/ha, ranged from 4374 (Peguis) to 6425 (Fairfield) in 1977 and from 3028 (Klages) to 4871 (Fergus) in 1978. Protein (N × 6.25) contents were lower in 1977, 11.3 to 13.1 vs. 13.1 to 14.3% of dry matter. During the following winters, each cultivar was used as 87.5% of a standard diet fed ad libitum to eight pigs from approximately 25 to 93 kg liveweight. Within feeding trials I and II, growth rates (averaging 798 ± 19 and 786 ± 24 g/day, respectively), efficiencies of feed conversion (EFC) and carcass measurements were not significantly (P > 0.05) affected by cultivar. However, the trend for diets based on two-row cultivars to be superior in EFC was supported by their higher apparent digestibilities of energy (80.8 vs. 71.8%) and of nitrogen (73.5 vs. 65.7%) in the 1978 diets. A palatability study using these diets indicated the pigs’ preference for two-row over six-row barleys.

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first- and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second- or third-cut grass silage (550 g kg-1 dry matter), rolled barley (435 g kg-1 dry matter) and a mineral-vitamin mixture (15 g kg-1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first- or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first- and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.

Number Of Males

Twelve female desert goat kids and an equal number of males were used to study meat production potential of desert goats at Kuku Research Station, Khartoum North, Sudan. The kids were kept in two separate groups according to sex. Kids were fed ad libitum a complete diet (a concentrate mix and green lucerne) for 147 days from 12 July to 10 Oct 1997.Male kids consumed more dry matter, had significantly greater liveweight gain and had heavier slaughter weight and superior feed conversion efficiency than females. Carcass weight was significantly greater in males than females but females dressed out heavier than males. Male carcasses had more muscles and bone while female carcasses had more fat and trimmings.Male goat kid carcasses yielded significantly (P<0·001) heavier wholesale cuts as single short forequarter and neck while female kid carcasses yielded heavier wholesale cuts as leg and chump, best end of neck as well as significantly (P<0·01) heavier loin and breast.

Ad Libitum Feeding

An experiment was carried out to determine which feeding method maximised feed intake of growing pigs and to record growth rates, feed conversion efficiency and backfat measurements. There is an increasing tendency for dry fed pigs to be fed ad libitum or to appetite in order to increase growth rates and throughput of building.Limited information is available on how the modern genetically improved pig will respond to high levels of feeding and whether ad libitum feeding will encourage higher feed intake than feeding to appetite either wet or dry.

A feedlot experiment with Hereford steers of initial liveweight of 249 � SE 3.0 kg was done to investigate the production responses to the addition of monensin either in the feed (30 ppm) or in intraruminal controlled-release capsules (CRC). The ration was 90% concentrate (94.3% sorghum, 3% tallow, 2.7% minerals), 10% cotton seed hulls with the following treatments: (A) control, (B) 30 ppm monensin in feed, (C) 50 mg monensin day-1 CRC, (D) 100 mg day-1 CRC, (E) 200 mg day-1 CRC, and (F) 300 mg day-1 CRC. The dry matter intakes and growth rates of the six groups (A to F) were 7.57 and 1.32; 6.56 and 1 .I 3; 7.60 and 1.35; 7.08 and 1.24; 7.39 and 1.35; and 7.05 and 1.23 kg day-1, respectively, with the dry matter intakes for monensin in feed (B) being lower (P < 0.05) than the remaining treatments, and for the same treatment the growth rates were lower (P < 0.05) than treatments A, C and E. The apparent feed conversion ratios (DMI kg-I LW gain) were 5.75, 5.92, 5.78, 5.86, 5.61 and 5.79, respectively, and did not differ (P > 0.05). Generally, the addition of monensin had no effect on carcase characteristics or on liver abscesses. It was concluded that the addition of tallow to the diet may have altered the rumen fermentation pattern sufficiently to prevent further benefit from the addition of monensin.

Compensatory Gain

ABSTRACT The objective of this study was to evaluate the effects of compensatory gain associated with the use of 10ppm ractopamine after a period of feed restriction in finishing pigs on performance, carcass and meat quality. Twenty castrated males and 20 females, at 110 days of age and 66.137±6.13kg live weight, were submitted to four treatments using a 2 x 2 factorial design (fed ad libitum or with 20% restriction between 0(21 days of age and fed with or without 10ppm ractopamine for 22(42 days of experimentation), with 10 replicates (animals). There was no interaction between the factors for any of the evaluated parameters. Animals treated with ractopamine presented better weight gain (1.083 versus 1.259kg), feed conversion (2.910 versus 2.577), warm and cold carcass weight (86.08 versus 89.00 and 83.46 versus 87.20kg, respectively), loin depth (63.02 versus 68.40mm), loin eye area (41.43 versus 46.59mm2) and muscle fiber diameter (27.48 versus 35.85μm). Animals submitted to feed restriction followed by ad libitum feed presented compensatory gain without losses to carcass and meat characteristics, but with a reduction in the ethereal extract (2.19 versus 1.64%) and lower water loss due to thawing in the meat (11.35 versus 9.42%). The effects of compensatory gain after food restriction and ractopamine are independent of the parameters evaluated.

SUMMARYIndonesian Ongole and swamp buffalo bulls were fed ad libitum a diet of elephant grass (Pennisetum purpureum) with five levels of rice bran (0, 1·2, 2·4, 3·6 and 4·8 kg/head/ day) in a study lasting 161 days. Measurements were made of the digestibility of the diet, the balances of nitrogen, phosphorus, calcium and water and the metabolizability of the gross energy. Using multiple regressions, the daily intakes of metabolizable energy were partitioned between maintenance and growth.Feeding rice bran stimulated appetite, initially improved feed conversion efficiency and increased growth rates. Each additional kilogram of rice bran fed depressed grass dry-matter intake by 0·8 kg in the buffaloes and 0·6 kg in Ongoles. Rice bran had little effect on digestibility of dry matter, organic matter and energy. Metabolizable energy contents of rice bran and elephant grass were calculated to be, respectively, 9·5 and 8·2 MJ/kg dry matter. Nitrogen and phosphorus status was improved in the supplemented animals but the balance of calcium was adversely affected. Voluntary feed intake was always higher in the buffaloes but the differences were reduced with increasing rice-bran supplementation.Metabolizable energy requirements for maintenance and growth did not differ significantly between Ongole and buffaloes and were similar to values calculated for British animals.

Western Victoria

An experiment at Hamilton in western Victoria from June to October 1972 examined the feasibility of fattening two-year-old Corriedale wethers from 30 to 50 kg liveweight when fed simple rations in feedlots. Using a factorial design, treatments compared were mid-season or late cut pasture hay offered ad libitum and oat grain fed at 0, 0.25, 0.50 kg head-1 day-1 or ad libitum. Two additional groups were set stocked on green pasture; one of them was offered oat grain ad libitum. Performance of sheep in the feedlot (intake, liveweight and carcase gain, feed conversion and wool production) was influenced by hay type and level of oat feeding. Liveweight gain over the period of feeding increased linearly until oats comprised about 50 per cent of the daily dry matter intake, but the highest liveweight gain in the feedlot (127 g day-1) occurred when sheep were given a ration consisting of 25 per cent mid-season hay and 75 per cent oats. Sheep on pasture gained at an average of 146 g day-1. Irrespective of composition of the ration, liveweight gain increased by 20 g day1, carcase weight by 15 g day-1 and wool by 1.7 g day -1 for each additional MJ of metabolizable energy intake.

Inclusion Level

Potato steam peel (SP) is a by-product of potato processing where the peel is removed after steaming. It typically contains 15 ± 3% dry matter, 16 ± 1% crude protein, 0.55 ±.05% lysine, 0% methionine/cystine and 6% ash (dry matter basis). Steaming effectively deactivates the proteolytic enzyme inhibitors and partially denatures the starch. SP was evaluated in a digestibility trial and at levels from 0 to 30% DM in two feeding trials. The digestibility (%) of SP by pigs was found to be 88.4 (DM), 80.1 (CP) and 86.1 (DE). In the first feeding trial diets containing levels of 0, 10, 15, 20, 25 and 30% SP supplemented with methionine resulted in similar growth performance and carcass characteristics. In the second feeding trial, a comparison was made between a constant level of inclusion and an increase in inclusion level with age. Results showed no difference in growth performance or feed consumption among treatments. It is concluded that SP can be incorporated in diets for growing-finishing pigs at levels up to 30% DM. No change in performance resulted from increasing level of inclusion with age. Key words: Potato, steam peel, pigs, digestibility

Ad Libitum Feeding

In previous experiments in this series, giving dry meal through a hopper with ad libitum feeding resulted in a poorer carcass feed conversion ratio than giving meal as porridge in a conventional trough (D. C. Patterson, unpublished data). In a further experiment a novel feed hopper was assessed with meal feeding. This hopper was designed to give a form of wet feeding and had nipple drinkers positioned within the trough so that pigs could not drink directly from the nipples, instead water was spilled directly onto the meal in the bottom of the trough. No other water was available to pigs on this treatment.

Four Levels

Forty, Friesian x Jersey bull calves were fed diets comprising factorial combinations of milk, either whole (4.0 per cent fat) or skimmed (0.1 per cent fat) milk, fed at the rate of 4.5 kg day-1 until the calves were ten weeks old, with crushed barley at four levels from two to 18 weeks of age. The four levels of barley were 0, 25, 50 and 75 per cent of the dry matter intake of the calves. The calves had access to hay ad libitum throughout the experiment. The restricted quantities of skimmed milk fed to the calves did not support rapid gains in liveweight, even when supplemented with high levels of barley. The addition of barley to the diet of the calves reared on whole milk produced no response in terms of growth rate (0.54 kg day-1). However, the calves reared on skimmed milk had greater growth rates when their diet contained 25 per cent barley than with no barley, 0.36 kg day-1 and 0.28 kg day-1 respectively. Further additions of barley did not produce additional responses in growth rate.
