Two experiments were conducted to examine whether the chemical nitrovin, a gudnidine derivative, would promote growth in pigs. In the first experiment, conducted at the Agricultural Research Station, Cressy, Tasmania, the addition of 20 p.p.m. nitrovin significantly increased liveweight gain by 5.5 per cent and feed conversion by 5.2 per cent. In the second experiment, conducted at the Agricultural Research Station, Wollongbar, N.S.W., the addition of 23 p.p.m. nitrovin significantly increased liveweight gain by 11.3 per cent but had no effect on lean in the ham. Feed conversion efficiency (not statistically analysed) was 10.6 per cent more efficient in pigs supplemented with nitrovin.

SUMMARYAllowances of about 1·4M, 1·8M, 2·2M, 2·6M, 3·OM, and 3·4M (M = feed required for maintenance) were compared for pigs growing over the live-weight ranges 20·40, 40·60, 60·80, and 80·100 kg, with feed conversion efficiency (FCE) as the main response criterion.Response to increased digestible energy (DE) allowance was curvilinear; FCE improved rapidly up to 2·2M-2·6M, and changed much less with intakes above 2·6M. It is concluded that optimum FCE occurs at about 2·7M for pigs of 30 kg and at about 3·OM for pigs of 50, 70 and 90 kg.Allowances of dietary DE suggested by the Agricultural Research Council correspond to 2·56M, 2·95M, 3·04M and 3·08M for pigs of 30, 50, 70 and 90 kg live weight, respectively. It appears that these are near to the optima in promoting the best FCE.Changes of −25%, −15%, −5%, +5% and +15% in daily intake around the optimum levels caused FCE to deteriorate by averages of about 13%, 4·5%, <1%, <1% and 4·5% respectively. Daily weight gains would then change by about −34%, −18%, −5%, +4% and +10%, respectively.

The efficacy of diatomaceous earth (DE) on growth rate, egg production and on increasing feed conversion efficiency in deep litter raised layer hens was evaluated. The study was conducted at Mukono Zonal Agricultural Research and Development Institute (MUZARDI) in Uganda. Worms were collected from fresh intestines of indigenous chicken obtained from Kalerwe chicken market near Kampala. The DE was mined in Pakwach (formerly Nebbi) district in Northern Uganda. Chickens of the Lohmann Brown breed raised on deep litter were studied. At 7 weeks the birds were divided into 5 treatment groups, A, B, C, D and E each composed of 40 birds. Groups C, D and E were given an oral dose containing 250 embryonated eggs of A. galli while groups A and B were not infected. The chicks were weighed; and subjected to feeding trials as arranged below: A – Non-infected birds on DE (4%) supplemented diet; B –non-infected birds on neither piperazine (a conventional de-wormer) nor DE; C – infected birds on DE supplemented diet; D – infected birds on piperazine; and group E – infected birds on neither DE nor piperazine applied. Fecal samples were collected and analysed in the laboratory biweekly at week 16 till week 22 respectively for fecal egg counts. In a subsequent experiment, day-old layer chicks from Lohmann Brown strain but different from those used in earlier experiments, were used to assess the effect of DE on egg production. At 17 weeks of age the 420 were divided as follows: 6 treatment groups each having 7 replicates and each replicate having 10 birds. This study showed that DE can be used successfully in growing pullet diets to correct nutritional mineral imbalance since it supplies more than 14 trace elements and other elements. Diatomaceous earth also enables pullets to cope with Ascaridia galli load; and 2% DE supplementation did not have significant improvement on egg production as compared to no supplementation at all. However, reduction in egg production was experienced when supplementation with levels of DE higher that 2% was applied. Results from biweekly fecal analyses showed significant differences in fecal egg counts (p<0.05); and treatment by group (p<0.05).

A series of experiments measured the effect of amino acid, copper, and vitamin B supplementation of 80 : 20 wheat--meat meal or wheat-meat and bone meal diets for Large White pigs during the growth phase between 18 and 45 kg liveweight. Diets were fed under a restricted feeding system. The addition of l-lysine to the diet increased nitrogen retention, liveweight gain, feed conversion efficiency, and lean content of the ham in experiment 1, and increased liveweight gain and feed conversion efficiency in experiment 2. No response to a lower level of l-lysine was obtained in a third experiment. There was no apparent effect of supplementary dl-methionine, either alone, or in combination with 1-lysine. A 21-fold increase in liver copper levels occurred in pigs supplemented with 250 p.p.m. copper, but no apparent effect on liveweight gain, feed conversion efficiency, or lean in the ham was detected. There was no apparent effect of a supplement containing riboflavin, pantothenic acid, and nicotinic acid on liveweight gain, feed conversion efficiency, or lean content of the ham.

The response to dietary lysine of liquid or crystalline form was examined in pigs fed on cereal protein dietsover the range of live weight from 25.0 to 95.0 kg. Forty individually fed growing pigs (20 gilts and 20castrated males) were allocated to four isonitrogenous diets consisting of barley, undehydrated distillers solids and a mixture of minerals and vitamins with lysine supplementation of 0.9 or 3.2 g pure lysine per kg DM in liquid or crystalline form to provide 7.1 or 9.1 g/FU total lysine, respectively. The pigs were given feed on a restricted scale twice daily. A high level of lysine supplementation significantly increased the growth rate and improved the feed conversion efficiency (p

The effects of replacing all or part of the protein supplied by meat and bone meal with whale meal or whale solubles were studied in four experiments with growing pigs fed diets based on wheat and barley. The growth rate and feed conversion efficiency of pigs receiving whale meal were equal to those fed meat and bone meal, whereas the performance of pigs fed whale solubles was inferior. Both whale meal and whale solubles contained mercury which accumulated in the tissues of growing pigs. The level of mercury accumulated was related to the dietary concentration and type of whale product, the period of time during which it was fed, and the type of carcase tissue. Whale meal contained more mercury than whale solubles and produced higher concentrations of mercury in the tissues. The levels of mercury in the tissues of pigs at 45 kg liveweight were lower than those of pigs at 80-85 kg liveweight. When the diets included more than 1 per cent whalemeal or 3 per cent whale solubles, the carcases contained more mercury than is tolerated by the health standards.

SUMMARYDried poultry manure, produced locally by sterilization and drying, was evaluated as an addition to a conventional diet, at levels of 10, 20 and 30%, for growing pigs from 23 to 85 kg live weight. The 32 pigs remained healthy and the dried manure had no apparent adverse effect on the carcasses.There were significant linear relationships between the amount of manure added to the conventional diet and growth rate, feed conversion efficiency and certain carcass characteristics. For every 10% addition of manure, growth was reduced by 0·02 kg/day, feed conversion efficiency by 0·25 units and killing-out percentage by 0·96. The dried manure contained about 30% crude protein and was a rich source of minerals.

Twenty-four (24) indigenous growing pigs were selected and randomly divided into 4 treatment groups consisting of 6 animals in each group penned individually and provided with the facility of separate feeding and watering to each pig. Sweet potato (Ipomoea batatas) meal (roots and leaves at 1:1 ratio) was incorporated in the diet to replace standard pigs grower ration at 0% (G1), 25% (G2), 50%(G3) and 75% (G4). During the feeding trial of 90 days, it was observed that the average dry matter intake was higher in G2 followed by G3 and G1 being the lowest. The feed conversion efficiency and average daily gain decreased as the level of sweet potato meal increased. However there were no significant differences (P>0.05) among the different treatment groups in regards to feed conversion efficiency and average daily gain. From the digestibility trial, no significant differences (P>0.05) were observed in the digestibility co- efficient of dry matter, crude protein and crude fibre among the different treatment groups. It is concluded that sweet potato meal can replace standard pig grower ration up to 75% without any adverse effect on growth, feed conversion efficiency and nutrient utilization.

The initial growth of turmeric is rather slow and takes about 4-5 months to cover the inter space. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background the experiment on effect of intercrops on growth and yield of turmeric was conducted at Agricultural Research Station, Bhavanisagar. Among the different intercrops, turmeric with cowpea recorded the maximum fresh rhizome yield per hectare (30.78 t ha-1) while turmeric + bhendi registered the maximum B:C ratio (2.68:1). Monocropping of turmeric recorded the lowest B:C ratio (1.67:1) among all the treatments.

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.

Metabolic energy budgeting (MEB) was used to evaluate evolution over 30 years (1980–1981 to 2010–2011) in New Zealand southern North Island ‘hill country’ sheep and beef cattle systems. MEB calculates energy required by animals for body weight maintenance, weight gain or loss, pregnancy, and lactation to estimate the system feed demand and thereby provide a basis for calculating feed conversion efficiency. Historic production systems were reconstructed and modeled using averaged data from industry surveys and data from owners’ diaries of three case-study farms and reviewed for patterns of change over time. The modeling indicated that pasture productivity was 11% lower and herbage harvested was 14% lower in 2010–2011 than in the early 1980s. This productivity decline is attributable to warmer, drier summer weather in recent years. However, primarily through increased lambing percentage, feed conversion efficiency based on industry data improved over the study period from 25 to 19 kg feed consumed per kg lamb weaned, while meat production rose from 137 to 147 kg per ha per year. Similar improvements were observed for the three case farms. The New Zealand MEB model was found effective for analysis of tropical beef production systems in Sabah, Malaysia.
