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

Twelve bulls within the age period 113—294 days were used in an experiment in which the effect of formaldehyde treatment of protein on the live weight gain and feed utilization was studied. Their rations were a combination of a protein concentrate mixture, barley, mineral and vitamins according to nutrient requirements for a growth rate of 1000 g/animal/day. Oats and barley straw was available ad libitum. In the experimental group the protein concentrate mixture was treated with formaldehyde, 0,88 g/100 g crude protein, whereas in the control group it was untreated. The proportion of treated protein was 45 % of the total protein in the diet. The study involved feeding trials, digestibility and nitrogen balance trials, and rumen fluid investigations. The live weight gain of the bulls in the experimental group was 10 % better than that of the control group. The amount of feed used per kg live weight gain was 8 % less in the former group than in the latter. The differences in both cases were, however, not significant (P > 0,05). The differences in the digestibility and nitrogen balance and in the pH, ammonia and VFA concentrations of the rumen fluid between the groups were small and insignificant (P > 0,05).

AbstractAn experiment was undertaken to compare the productivity of crossbred ewes, produced by crossing Texel sires with Rouge de l’Ouest (Rouge) dams and Rouge sires with Texel dams, relative to purebred Texel and Rouge ewes. The purebred and crossbred ewes were crossed with Rouge and Texel sires. The proportion of productive ewes was similar in the purebred and crossbred ewes with an average figure of 0·92. Irrespective of crossing sire, Rouge ewes produced 0·48 more lambs per ewe lambed than Texel ewes (P < 0·001). The two crossbred ewe types (Texel ✕ Rouge and Rouge ✕ Texel) each produced similar numbers of lambs (on average 1·92 lambs per ewe lambed). Individual heterosis values for ewe fertility and prolificacy were small and not significant (–1·67 for the proportion of productive ewes and –3·14 for the number of lambs born per ewe lambed). Maternal heterosis values were also not significant but were of larger magnitude (6·26 for ewe fertility and 3·12 for prolificacy). Lamb mortality (number of lambs born dead per ewe lambed) at birth was similar for purebred Rouge (0·44) and Texel (0·30) ewes and was significantly reduced by crossbred matings and mating the crossbred ewes (individual heterosis –30·68, P < 0·10; maternal heterosis –80·23, P < 0·001). Individual and maternal heterosis values for lamb growth rate from birth to six weeks were 8 (P < 0·05) and 4 (P > 0·05) respectively. Lamb growth rate from birth to weaning was significantly lower in lambs from Texel ewes compared with those from the other genotypes (P < 0·05). Individual and maternal heterosis values for live-weight gain from birth to weaning were 5 (P < 0·10) and 5 (P < 0·01). The results of the current study demonstrate the superior performance of purebred Rouge ewes compared with purebred Texel ewes in terms of prolificacy and lamb growth rate from birth to weaning. However, both breeds had high lamb mortality at birth. Crossbreeding led to the production of hybrid ewes which had relatively high prolificacy with low levels of dystocia and lamb mortality.

Series Of Experiments

It is now widely accepted that the subcutaneous implantation of stilboestrol or hexoestrol increases the rate of live-weight gain in lambs and cattle. In sheep it is generally considered that for a feeding period of up to 12 weeks a single implantation of hormone produces an adequate growth response. Perry et al.(1951), Stephens & Thompson (1952) and Bell et al.(1954) reported no advantage from repeated implantations during the experimental period. In a series of experiments at this Institute (Preston & Gee, 1957a) it has been noticed that the major part of the increased weight gain takes place during the first six weeks after hexoestrol implantation.

SUMMARYYoung, uncastrated male cattle (initial weight 80 kg, final weight 240 kg) were used to evaluate brewers' dried grains as a protein source (17 or 36% of the concentrate mixture), in comparison with soyabean oil meal (6% of the concentrate mixture). There were no significant effects on feed intake or average daily live-weight gain. The killing-out percentages for the three treatments were 49·2; 48·6 and 46·9 respectively (P < 0·001). There was a lower fat deposition (P < 0·01) in animals receiving the higher level of brewers' dried grains, and the degree of rumen parakeratosis was less (P < 0·001) with the diets containing grains.

SUMMARYTwenty-seven groups of Finnish Landrace × Dorset Horn lambs, each of two males and two females, were offered daily quantities of 180, 248 or 343 g milk substitute dry matter (DM) for 21, 29 or 40 days. The environmental temperature was 18°C during the first 21 days of rearing, and concentrate pellets and clean water were always available. From 22 to 48 days of age the lambs were offered 150 g of hay per week.For lambs offered 180 g milk substitute DM, increasing the number of days before weaning increased the daily live-weight gain over the 47-day experimental period. For daily allowances of 248 and 343 g of milk substitute, greater gains were effected only by delaying weaning from 21 to 29 days.Increasing the daily allowance of milk substitute DM had little effect on the daily gain of lambs weaned after 21 days but increased gain by lambs weaned at 29 days. For lambs weaned after 40 days growth rate was increased only by the first increment of milk substitute DM. Intake of solid food began when the lambs were 3 weeks old and total intake of concentrates was inversely related to total quantity of milk substitute DM consumed and in general was less when weaning was later.The overall efficiency of conversion of total DM consumed to live weight was positively related to total milk substitute DM consumed and tended to be greatest when weaning was later. A daily allowance of 180 g milk substitute DM for 21 days gave the lowest food cost per unit of live-weight gain.The incidence of navel sucking is discussed.

There was studied the distribution of postpartum pathology of cows and disease of calves in early postnatal period in conditions of Nizhny Novgorod region. It was established, that the new tissue drug &#34;bio-tec&#34; has positive influence on reproductive function, safety and live weight gain of calves. The postpartum pathology of cows gained wide spread among nizhnynovgorod farms up to 80%, e.g. Endometritis and subinvolution of uterus 37,4 and 23,9 respectively. By clinical examination of newborn calves it was established, that in the first month of life 50,3% fall ill with gastrointestinal diseases of various etiologies. The die-off of calves reached 29%. Using &#34;bio-tec&#34; drug to dry cows decreased the percentage of postpartum pathology by 35% and reduced the time of involution of uterus for 11,2 days; the service period reduced by 21,2 days and the diseases of newborn calves was twice less, that increased the energy of growth and in 16 month age heifers went over animals of the control group by 10%, that allowed their earlier use for reproduction. So, the results of conducted research showed, that twice a day injection of tissue drug &#34;bio-tec&#34; to dry cows in 10ml dose 60-55 and 40-35 days to calving contributes reducing of obstetric pathology. Subsequent use to calves in 4ml dose in 5-8 days age increases the safety of calves and positively influences the live weight gain, that in fact gives abilities of more effective cattle breeding.

SUMMARYWhole milk was given once daily to three groups each of 18 Friesian heifer calves and concentrates and hay were also available. Calves in one group received 2·4 kg milk/day and in a second 3·0 kg milk/day and in both of these groups individual calves were weaned when their daily intake of concentrates reached 400 g. In the third group the calves received 3·0 kg milk/day and were weaned after 28 days. Concentrate and hay intakes were not significantly affected by the treatments. Mean growth rate over 56 days increased with increasing quantity of whole milk offered but the differences between treatments were not significant. The performance of calves given whole milk was compared with the performance achieved in previous experiments where milk substitute was given. It was estimated that 1 kg whole milk gave the same live-weight gain as 170 g milk-substitute powder. From this estimate price/cost relationships were determined to indicate when whole milk or milk substitute should be fed to calves.

Digestible Crude Protein

SUMMARYIn-lamb ewes were given 38, 58 and 82 g of digestible crude protein daily at a constant energy intake of 1600 kcal ME per head daily during the last 6 weeks of gestation. There were no significant differences between treatments in live-weight gain of the ewes, lamb birth weight or ewe net body-weight change (the difference between live-weight gain over the experimental period and live-weight loss at lambing).Digestibility coefficients for the diet components and nitrogen balances were determined on three ewes per treatment during weeks 15-16 and 19·20 of gestation. No differences in the apparent digestibility of the diet components were observed between the two periods. The apparent digestibility of crude protein increased significantly (P > 0·001) with increase in crude protein intake. A significant linear relationship (P<0·01) was found between digestible crude protein intake and nitrogen retention; daily N retention increased by 0·19 g per kg W0·73 for every 1 g per kg W0·73 of apparent digested nitrogen intake per day.

SUMMARYThe effects of three levels of concentrate supplementation on the live-weight gain and intake of roughages of 12-week-old British Friesian female calves were examined. Each supplement was offered for 12 weeks to two replicates of five calves which were group fed. The following six roughages were studied; high quality hay, dried grass wafers, grass silage, barley straw, poor quality hay and maize silage. The digestibility of the roughages was measured with sheep by total collection of faeces.Increasing the level of concentrate supplementation gave linear increases in live-weight gains of calves with all roughages, the greatest response occurring with roughages of low digestibility. The intake of roughage was depressed by increasing the level of concentrate supplementation, the greatest depressions occurring with roughages of high digestibility. Live-weight gains and roughage intakes were higher with dried grass wafers and lower with maize silage than would be expected from their respective digestibility coefficients.Multiple regression equations were calculated to relate live-weight gains or roughage intakes to concentrate intake and roughage digestibility. These equations predict from the digestibility of a roughage, the amount of concentrates required daily to produce a given live-weight gain, and the amount of roughage which is eaten under these circumstances.

The research (2018-2019) was conducted in the conditions of a peasant farm in the Voronezh region. The paper evaluates the indicators of the growth rate and meat productivity of the preserved gene pool groups of guinea fowl. The experiment involved three groups of daily guinea fowl of 200 heads of different genetic origin: lines of the Volga white breed (the original VB-4, selected by the rate of live weight gain and reproductive characteristics; autosex VBA-1, selected by the color of down, feather and productive characteristics) and gray-speckled guinea fowl of unknown origin. Studies have shown that the live weight of guinea fowl of the VBA-1 line exceeded the live weight of poultry from other groups of guinea fowl, a significant excess was noted at 8, 12 and 13 weeks of age. The greatest coefficient of variation of the trait was observed at 8 weeks of age. The analysis of relative gain in live weight of guinea fowl showed that up to 10 weeks of age, the highest relative growth rate of guinea fowl of all experimental groups was observed (14.0-17.0 %). Starting from the age of 11 weeks, this indicator gradually decreased (4.3-13.4 %). It was found out that under the same conditions of keeping and feeding, the feed costs per 1 kg of live weight gain in guinea fowls of the VBA-1 line were less by 0.09-0.16 kg (3.11-6.33 %) compared to poultry of the VB-4 line and by 0.2-0.4 kg (5.49-12.82 %) compared to their gray-speckled peers. The results of anatomical cutting of guinea fowl carcasses showed that the experimental groups of poultry significantly (P< 0.05) differed among themselves in the degree of development of internal organs and tissues. The yield of edible parts was 60.2-61.1 %, depending on the group of poultry. The large live weight noted by us in linear poultry is the reason for their better meat productivity, which is directly related to an increase in the absolute mass of the eviscerated carcass, its edible parts, muscles and bones. Based on the data obtained, the optimal age of poultry slaughter for meat was determined at 10-12 weeks of life.
