SUMMARYFourteen Large White female pigs were mated at about 6 months of age and 90 kg live weight. Three of them gave birth to very small litters and were slaughtered a week after parturition at an average live weight of 166 kg. From the other 11 females 6-week-old litters with average an of 8-8 piglets were weaned. Twenty-four days after weaning the mothers, averaging 152 kg live weight, were slaughtered. Performance was compared with that of unmated females slaughtered at 90 or 130 kg live weight. After subtracting the amount of feed used normally for the production of weaned litters from the total feed consumption of the 14 females which farrowed, the feed intake per 1 kg live-weight gain was 3·67 kg, as compared with 3·43 kg and 4·46 kg in the groups slaughtered at 90 or 130 kg live weight, respectively. The average daily protein deposition in the 14 females together with their litters was 119·6 g, compared with 104·1 and 81·4 g in the control groups.

Treatment Groups

SUMMARYTwenty-eight Landrace × (Landrace × Large White) young female pigs (gilts) were allocated to one of four treatment groups at about 75 kg live weight. The gilts were mated at second oestrus and suckled their piglets for 35 days. Gilts were slaughtered 14, 21, 28 or 35 days after weaning. The ‘effective’ food conversion ratios (i.e. total gilt plus litter feed intake (kg) divided by total gilt weight gain plus litter weaning weight) of the four groups were 5·22; 4·70; 4·62; and 4·56 respectively. The differences were not statistically significant.Neither carcass weights nor individual joint weights were significantly affected by treatment. Samples of 11 middle sections from the 14-, 21- and 28-day slaughter groups were boned and cured. Bacon produced from the streak blocks had poor colour, texture and moisture-holding capacity. It was concluded that streak blocks from gilts that had farrowed were unsuitable for curing as streaky bacon.

SUMMARY1. The growth, feed consumption per unit weight gain, carcass characteristics and some aspects of meat quality were studied in two trials with crosses derived from Landrace (L), Pietrain (P), Hampshire (H) and Large White (LW) breeds.2. In Trial 1, 96 pigs of both pure Landrace and LW(× (L♀ × P♂)♂ origin were studied up to slaughter weights of 64 and 91 kg live weight. In Trial 2, Landrace, LW♀ × (L♀ × P♂)♂ and LW ♂x (P♀x L♂)♂, (H♀ × P♂ × L♂ and (H♀ × P♂)♀ × LW♂ pigs were compared up to 91 kg live weight using 48 pigs of each type.3. All crossbred types showed better economy of production than Landrace when assessed by live-weight gain and feed consumption per unit weight gain. Their carcasses contained greater quantities of lean meat and similar quantities of rind, bone and fat than Landrace at comparable weights, but they exhibited a variable tendency to poorer meat quality. LW × (L × P) and LW × (P × L) carcasses at 91 kg live weight were shorter than Landrace; 4% and 14% of pigs in trials 1 and 2 respectively were less than the currently acceptable length of bacon pigs (775 mm). (H × P) × LW and (H×P)×L carcasses at this weight were much shorter; 34% and 38% respectively were less than 775 mm.

Total Weight Gain

A total of 48 large white pigs were used in an experiment to investigate the use of exogenous testosterone on the growth of pigs. The pigs were randomly selected as day old piglets, balanced for weight with equal number for each sex, and allotted to two treatment groups, T1, which received Testosterone Enanthate (TE), intramuscularly, weekly, for 24 weeks and T2, the control, which received no hormone but blank injections. Dosage was based on live weight (1.2mg/kg live weight). Corn oil served as the vehicle. The parameters measured include Total weight gain (TWG), Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and Feed Conversion Ratio. The results obtained showed that exogenous testosterone increased weight gain significantly (p<0.05) in both sexes than their respective controls. The same trend was observed for feed intake and feed conversion. Exogenous testosterone also indicated pronounced sex effect on the pigs in this study with males having significantly (p<0.05) higher values than females. It can be concluded from this study that exogenous testosterone can be used to accelerate growth thereby finishing the pigs early. A withdrawal period of 4 weeks before slaughter is however recommended.

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.

The studies were conducted in growing quail meat production at the age of 1–35 days in the research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. The research goal was to establish effective levels of additional introduction of Selenium in fodder for growing quail by comparing them to some zoo–technical indicators. Five groups of 100 quails were formed.  The quails of the Control Group were fed a standard diet without the inclusion of additional Selenium. The quails of the trial groups received a standard diet supplemented with selenium: group 2 – 0.1 mg, group 3 – 0.2 mg, group 4 – 0.3 mg and group 5 – 0.4 mg / kg feed. For a determine the effect of selenium on the productive qualities of quails was conducted taking into account their of preservation, feed intake, body weight is determined and calculated feed cost per 1 g of live weight gain. During the study established that the level of preservation quails high enough in the experimental groups, the best body weight was observed in animals consuming an additional 0.4 mg of Se, and the lowest feed consumption per 1 kg of growth – from poultry which were fed 0.2 mg Se. Thus, investigated of trace elements in the indicated doses increases the productivity of quails and decrease feed costs per 1 kg of live weight gain

SUMMARYVarious physiological characteristics of castrate male sheep fed ad libitum were studied between 1986 and 1987 in Australia. The sheep were between 20 and 45 kg live weight (LW) before and during fattening. Sequential data on body composition, estimated from TOH space (starting at 10 kg), established that the weight gain contained 19% fat and 13% protein below c. 26 kg LW and 55% fat and 10% protein above. For a given feed intake, the rate of fat gain was constant but the rate of body protein gain was 45% lower above 26 kg LW. Voluntary feed consumption per unit weight peaked at 26 kg LW and declined thereafter. There was an increase at 45 kg LW in weight of rumen digesta per unit feed intake and in digestibility; metabolizable energy (ME) per kg feed was increased as a result by 6–9%. Efficiency of use of ME, determined by calorimetry, increased from 44% in the lower weight range to 53% in the higher; utilization of nitrogen decreased from 37 to 28%. Partition of ME and energy gain suggested that the energetic efficiency of neither fat nor protein deposition changed between the two weight ranges. Change in the amount of DNA (‘cell number’) rather than g tissue/mg DNA (‘cell size’) accounted for weight change in three muscles and most digestive organs. Exceptions were the rumen, in which cell number and size both contributed to gain and the large intestine, in which cell size diminished during growth. It was concluded that fattening in sheep reflects diminution of the protein content of weight gain due to a decrease in the efficiency of protein utilization at the tissue level.

A study was conducted to establish the possibilities for replacing 5 and 10% of wheat in the combined feed for domestic quails with extruded bakery waste and to study its impact on the growth and productivity of quails. 270 domestic quails from the specialized meat production line WG were included in the experiment and divided according to the principle of analogues into 3 aligned groups: control, fed with mixtures without the inclusion of extruded waste from bakeries; experimental I, in the mixtures of which 5% of the wheat was replaced with extruded bakery waste and experimental II, in which 10% of the wheat in the mixtures was replaced by extruded bakery waste. The experiment continued until the age of 35 days. The following signs were monitored: mortality (%), live weight (g), average daily weight gain (g), feed consumption (g), feed conversion (kg/kg weight gain). The study showed that for the 35-day period, the quails from the specialized meat production line WG consumed an average of 812-817 g of compound feed, with an average increase of the weight gain 255-258 g. Under these conditions, the average feed conversion ratio is in the range of 3.15-3.20. In the course of the trial it was found that the replacement of 5 and 10% of wheat in the feed mixture with extruded bakery waste reduces the value of compound feed by an average of 0.85 and 1.7%, but does not affect the studied productivity traits and economic indicators from fattening. When summarizing the results for the 35-day period, the differences between the control and experimental groups on the studied productive traits are less than 2%, and the difference in the value of 1 kg weight gain between the groups is less than 1%.

This study was carried out to investigate the effect of shearing on fattening performance characteristics of Akkaraman and Awassi lambs that were fattened intensively. 10 Akkaraman and 8 Awassi male lambs were used in the study. During the fattening period, the animals were given 150 g of dried alfalfa and concentrated feed ad-libitum. In the study, Akkaraman and Awassi lambs were divided into two experimental groups as shearing and non-shearing. The total weight gains, daily live weight gains, feed consumptions and feed conservation coefficients of lambs before and after shearing were 8.017 kg, 286 g, 47.14 kg and 5.945 and 8.606 kg, 307 g, 42.21 kg and 5.029, respectively. On the other hand, total live weight gain of lambs without shearing was 7.802 kg, daily live weight gain was 279 g, feed consumption was 42.06 kg and feed conservation coefficient were 6.00. As a result of the study, the differences between some fattening performance means of shearing and non-shearing groups were statistically insignificant.

Whole Wheat

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

SUMMARYIn three successive years cows from an Aberdeen Angus cross Shorthorn herd were mated to pedigree Charolais, British Friesian and Hereford bulls. A comparison of the progeny of the three breeds of sire under controlled conditions was therefore possible using a random selection of dams for mating, and identical rearing of the calves. Results for live-weight gain of the suckled progeny were analysed and showed superiority of the Charolais breed over the other two when used in this form of beef cattle production.For birth weights and daily live-weight gains, particularly during the grazing period, the Charolais cross progeny showed superiority over the other two. There was a consistent although not always statistically significant tendency for these differences between the breed crosses to occur in the male calves only, the females showing little difference between breeds. The data also showed highly significant relationships between gestation period and birth weight, both within and between breed crosses.
