Live Weight Gain

This experiment was conducted to evaluate the effects of dietary supplementation of aloe vera extract (w/v) on growth performance of broiler. The present study explored the potentials of medicinal plants Aloe barbedensis mixture in broiler performance. For this purpose, 120 day old chicks were randomly assigned into five treatment groups, namely T0, T1, T2, T3 and T4. Each treatment group contained 24 chicks. The chicks were purchased from a local chick hatchery named Nourish Poultry & Hatchery Ltd. Birds were brooded up to 10 days and then reared in separate flock for 35 days in an open sided house. Each treatment group was further replicated into three sub-groups and each contained eight birds. Experimental birds in T1, T2, T3 and T4 were provided with aloe vera extract (w/v) @ 05, 10, 15 and 20 ml per liter of drinking water while T0 was maintained as control group. Relevant data were recorded throughout the experimental period and subjected to statistical analysis. The data on growth parameters (body weight gain, feed consumption, feed efficiency, water intake) and feed cost and gross return per broiler were evaluated. The results of the study revealed that the aloe vera supplemented groups showed higher live weight gain than untreated group. Aloe vera supplemented groups showed more live weight gain in the terminal stages of the experiment. Aloe vera (w/v) extract supplemented groups performed the best feed efficiency. The live weight gain and feed efficiency were significantly (P<0.05) better in the broilers provided water containing 15 ml/L aloe vera aqueous extract. Water intake, feed intake and abdominal fat deposition of broilers given aloe extract in drinking water were not different among each other. So, 15 ml/L aloe vera aqueous extract may be given to the broilers drinking water.Asian J. Med. Biol. Res. March 2017, 3(1): 120-126

SUMMARYIndonesian Ongole and swamp buffalo bulls that had previously been given 0, 1·2, 2·4, 3·6 or 4·8 kg/head/day rice bran plus ad libitum elephant grass were slaughtered after 161 days feeding. Abdominal depot fat, full and empty reticulo-rumen and cold carcass weights were recorded. Various carcass variables were measured and the 9–10–11 rib joints were dissected into bone, muscle and fat. Carcass gross energy was calculated from rib-fat content using previously determined regression equations. Feed efficiency was expressed in terms of the ratios of live-weight gain or carcass-energy accretion to metabolizable energy available for growth.Increasing supplementation with rice bran resulted in larger abdominal fat depots, higher dressing percentages, increased carcass fatness (and hence carcass gross energy) and improved rib muscle to bone ratios. Carcass conformation was unaffected by dietary treatment. When feed efficiency was expressed per unit live-weight gain, there was a decrease with increasing rice-bran feeding. Feed efficiency, expressed per unit of carcass energy accretion, improved with rice-bran supplementation and was generally higher in buffalo than in Ongole bulls. Dietary and species differences in feed efficiency could be primarily explained by the differential energy cost of deposition of, and the availability of energy from, carcass protein and lipid.

The Relationship

Data from Danish Progeny Testing Stations were used to investigate the relationship between the colour of meat and feed efficiency in pigs. For groups slaughtered during the summer there was a highly significant correlation. As the amount of feed consumed per unit live-weight gain declined so the meat became paler. For groups slaughtered in winter and for data pooled over the whole year, there was no significant correlation. Possible explanations of these findings are discussed.

The present study was carried out to assess the effect of concentrate on growth performances of both male and female lamb. For this purpose twenty four (12 male and 12 female) lamb aged about 5-6 months were selected and divided into three groups (Treatment group T1, T2 and control group T0). In each group having 4 males and 4 females lamb, all lambs were supplied green roughages ad-libitum, control group T0 was allowed no concentrate and treatment group T1 & T2 were supplied 100 gm & 200 gm concentrate mixture respectively for 90 days experimental period. Animals were weighed at 15 days interval. Significant differences of live weight gain among these three groups were found. Allowing 100 gm (T1) concentrate mixture along with green grass improved growth rate in both male and female lamb. Increasing of concentrate supplementation improved live weight gain (found in T2 group). Total live weight gain (kg) and average daily live weight gain (g/d) were 4.25±0.52 kg and 47.20±5.75 g, 5.38±0.83 kg and 59.73+9.17 g and 7.00±0.54 kg and 77.78±6.00 g in male lambs and 2.25±0.21 kg and 25.00±2.34 g, 3.18±0.32 kg and 35.39±3.63 g and 3.81±0.24 kg and 42.33±2.77 g in female lambs for the To, T1 and T2 groups respectively. Live weight was significantly (P<0.05) higher in male than female lambs. The results showed that 100 g concentrate supplementation with green roughages improved growth rate in lambs (male and female) under stall feeding condition. Increase of supplementation might improve nutrients supply to promote higher live weight gain.Asian J. Med. Biol. Res. June 2016, 2(2): 274-278

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB)  (T0), LPB+ 100g/100 met + 300g/100  lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.

SUMMARYTwo experiments were conducted to study the effect of type of cereal and time of weaning on the performance and voluntary intake of lambs.In the first experiment 20 early-weaned entire male lambs were given diets ad libitum during the fattening period from 15 to 40 kg live weight. The diets were based on either kibbled maize or rolled barley. A high feed efficiency and growth rate were achieved with both diets and differences between them were not statistically significant. The growth rates were 428 and 430 g/day. The cold carcass weights at 40 kg live weight were 19·0 and 19·9 kg and the conversion ratios of dry matter to live-weight gain were 2·33 and 2·22 for the rolled barley and kibbled maize diets respectively.In the second experiment a comparison was made of the performance of 36 sets of twin lambs, one of each set being weaned at either 6, 13 or 20 weeks of age and the other being left to suck the ewe outdoors. The lambs weaned at 6 weeks had better conversions of dry matter to live-weight gain than lambs weaned at 13 and 20 weeks. The respective conversions of dry matter to live-weight gain were 3·36, 5·64 and 5·52. The lambs weaned at either 13 or 20 weeks had a greater weight at weaning, a greater growth check at weaning and a lower rate of feed intake.

Significant Difference

ABSTRACTA trial compared the voluntary water intake of 72 purchased British Friesian bull calves fed at different nutrient intake levels by varying the type and strength of the milk replacer given to 5 weeks of age. There was no control group without water on offer. Water was offered from the 1st day the animals entered the unit. All calves received 4 1/day of either cows' milk (12 calves), milk replacer with 100 g fat per kg (24 calves), milk replacer with 170 g fat per kg (24 calves) or milk replacer with 200 g fat per kg (12 calves). Standard early-weaning pellets containing 190 g crude protein per kg and hay ad libitum were on offer from the 2nd day on the unit. Results indicated that voluntary intakes of water were highest with calves fed on cows' milk and lowest on the milk replacer with 100 g fat per kg given at the lowest mixing strength, although differences were only significant in week 5 (P ≤ 0·05). By covariance analysis, the effects of water intakes on live-weight gain and on pellet intake were examined. The regression coefficient of live-weight gain (weeks 0 to 5) (kg) on water intake (weeks 1 to 5) (1) was b= 0·056 (s.e. 0·021, P ≤ 0·01). The regression coefficient of pellet intake (weeks 0 to 5) (kg) on water consumption was: b= 0·082 (s.e. 0·031, P ≤ 0·01). There was thus a significant correlation of both live-weight gain and pellet intake with water intake. For each extra litre of water consumed per day, there was an extra pellet intake of 0·082 kg and an increase in live-weight gain of 0·056 kg. There was a significant difference in total water intake according to the initial live weight of the calf.

Cutting Frequency

Calliandra calothyrsus is a tree legume native to Mexico and Central America. The species has attracted considerable attention for its capacity to produce both fuelwood and foliage for either green manure or fodder. Its high content of proanthocyanidins (condensed tannins) and associated low digestibility has, however, limited its use as a feed for ruminants, and there is also a widespread perception that wilting the leaves further reduces their nutritive value. Nevertheless, there has been increasing uptake of calliandra as fodder in certain regions, notably the Central Highlands of Kenya. The present study, conducted in Embu, Kenya, investigated effects of provenance, wilting, cutting frequency and seasonal variation both in the laboratory (in vitro digestibility, crude protein, neutral detergent fibre, extractable and bound proanthocyanidins) and in on-station animal production trials with growing lambs and lactating goats. The local Kenyan landrace of calliandra (Embu) and a closely-related Guatemalan provenance (Patulul) were found to be significantly different, and superior, to a provenance from Nicaragua (San Ramón) in most of the laboratory traits measured, as well as in animal production and feed efficiency. Cutting frequency had no important effect on quality; and although all quality traits displayed seasonal variation there was little discernible pattern to this variation. Wilting had a much less negative effect than expected, and for lambs fed calliandra as a supplement to a low quality basal feed (maize stover), wilting was actually found to give higher live-weight gain and feed efficiency. Conversely, with a high quality basal diet (Napier grass) wilting enhanced intake but not live-weight gain, so feed efficiency was greater for fresh material. The difference between fresh and wilted leaves was not great enough to justify the current widespread recommendation that calliandra should always be fed fresh.

SUMMARYTwo experiments were carried out to study the effect of the ad libitum feeding of whole-milk substitutes, either warm or cold, and the availability of drinking water, on the level of food intake and live-weight gain of calves. Freshly cut grass or pasture was the sole source of solid feed.In Exp. 1 forty Hereford x Friesian male calves were reared individually indoors in a 2x2x2 factorial design experiment. The treatments were full-cream milk powder υ milk substitute, temperature at which the milk was offered, and drinking water υ no drinking water available to the calves. Fresh grass was cut daily and fed ad libitum to all animals from the sixth day of treatment.In Exp. 2, twelve Hereford x Friesian male calves were reared at pasture on warm or cold full-cream milk during weeks 1–7, and on milk substitute during weeks 8–15.During both experiments calves receiving warm milk drank slightly more than calves receiving cold milk; this difference was significant in Exp. 1 only. There was a tendency for calves receiving cold milk to make higher live-weight gains (0·05 < P < 0·1) when drinking water was available than when it was not. In Exp. 1, the rates of live-weight gain of calves receiving warm or cold milk substitute with drinking water available were 0·99 and 0·89 kg/head/day, respectively: for calves receiving full-cream milk powder the corresponding rates were 0·86 and 0·80 kg/head/day. When drinking water was not available the rates of gain of calves on warm or cold milk substitute were respectively 0·93 and 0·82 kg/head/day, and on full-cream milk powder, 0·94 and 0·55 kg/head/day.In Exp. 2 the rate of live-weight gain measured during the first 7 weeks, whilst calves were receiving full-cream milk powder, was 0·88 kg/head/day irrespective of the temperature at which the milk was given. During weeks 8–14 milk substitute was given, which resulted in rates of live-weight gain of 1·05 kg/head/day for calves receiving warm milk and 0–92 kg/head/day for calves receiving cold.The rates of gain attained on cold milk are considered adequate for rearing calves intended for an intensive system of production. It is also suggested that the use of cold milk could facilitate a marked decrease in the daily labour requirements associated with the artificial rearing of calves.
