A total sixteen female Black Bengal goats (BBG) considering average live weight were randomly divided into four equal treatments to study the effect of different level of concentrates supplementation on production and reproduction performance of BBG. The animals were assigned to adlibitum green grass and supplemented with different levels of concentrates at 150, 200, 250 and 300 g respectively. Live weight gain, Dry matter (DM) intake, Crude protein (CP) intake were increased significantly (p less than 0.01) with concentrate supplementation. Feed conversion ratio (FCR) and protein conversion ratio (PCR) were not significant on level of concentrate. The value of services per conception, birth weight of kids and growth rate of kids showed a positive effect on level of concentrate supplementation but not significant. Average daily milk yield of doe were increased significantly (p less than 0.01). Supplementation of concentrate mixture with 300 gm could be beneficial for BBG in Bangladesh condition.

Effect Of Age

The study was conducted with the objectives to understand the effect of age of native Pabna bulls on feed conversion ratio (FCR), digestibility and carcass yield characteristics. Fifteen Pabna bulls having five  in each age groups of 6 to12, 13 to 24 and 25 to 36 months  were fed   ad libitum mix silages of Splendida (Setaria splendida) and Andrpogan (Andropogon gyunus) grasses (1:1 fresh) and supplemented with a concentrate mixture at 1% of live weight (LW) for a period of 72 days. With the increase of age, and subsequently LW (initial LW: 98.2, 182.6 and 288 kg, respectively), there was significant decrease in dry matter (DM) intake as % LW (<0.05; 2.94, 2.61 and 2.36, respectively) and increased daily gain (<0.01; 294, 519 and 597 g/d, respectively). However, the feed conversion ratio (FCR) (>0.05; 10.88, 10.10 and 12.24, respectively) and DM digestibility (>0.05; 51.0, 48.1 and 49.1 %, respectively) of bulls were remained unchanged. In case of carcass yield characteristics, significantly lower yield grade (<0.01; 1.79, 1.27 and 0.20, respectively) of bulls of 25 to 36 years produced higher closely trimmed boneless retail cuts (CTBRC) (<0.01; 50.47, 51.64 and 54.14 %, respectively), retail cut (<0.01; 76.14, 78.55 and 83.48 %, respectively) and meat quality index (MQI) (<0.01; 67.28, 67.89 and 69.07, respectively) compared to younger bulls. It may, therefore, be recommended that beef cattle farming with native Pabna bulls of 24 to 36 months will give more daily LW gain and produce more CTBRC at a similar FCR compared to younger ones.Bang.

The study was undertaken to investigate the effects of concentrate supplementation with different protein levels on intake, digestibility and growth performance of Red Chittagong (RC) heifers fed urea molasses straw (UMS) based diet. Twelve RC heifers having average live weight of 124.83±43.15 kg and aged between 8 to 14 months were selected for 90 days feeding trial. Animals were divided into four groups having three animals in each and were randomly assigned to four dietary treatments in a Randomized Block Design (RBD). The experimental diets were formulated using urea molasses straw (UMS), German grass (Echinochloa grousgalli) with or without concentrate mix (having different levels of protein). All the animals received UMS ad libitum and German grass at the rate of 20% of total DM intake. In addition to UMS and German grass of control diet T0, animals on diets T1, T2 and T3 were supplied with concentrate mixture at the rate of 10% of DM intake containing 15, 20 and 25% CP, respectively. Average daily DM intake was 2.65, 3.06, 2.62 and 2.86 kg/100 kg LW for diets T0, T1, T2 and T3, respectively and the difference was non significant (P>0.05). The digestibility of DM, CP, EE, NFE and digestible nutrients (DCP, DEE and DNFE) for diets T1, T2 and T3 was significantly higher than those for diet T0. The daily average liveweight gain of RC heifers fed diets T0, T1, T2 and T3 were 100, 275, 333 and 291 g respectively (P<0.01). Concentrate mixture having 20% crude protein may be supplemented at the rate of 10% of DM intake per day for optimum growth of Red Chittagong heifers.

The experiment was conducted for a period of 56 days using 24 growing rabbits (4 to 6 weeks old) to evaluate the effect of citric acid (CA) on the growth performance. Concentrate mixture was fortified by 0, 0.5, 1.0 and 1.5% CA to 4 different groups of rabbit considering 6 in each. Green grass and concentrate mixture were supplied on ad-libitum basis. Growth rate increased 5, 8 and 12% respectively in 0.5, 1.0 and 1.5% CA supplemented groups (P>0.05). Total dry matter (DM) intake decreased numerically due to increased level of CA whereas, growth velocity increased with increased level of CA. Insignificant difference observed in terms of feed conversion ratio (FCR-DM intake/weight gain) among different groups but improved 6, 16, and 8 % respectively in 0.5, 1.0 and 1.5% CA offering groups. Over all numerically better performance obtained due to addition of CA in rabbit diet. So, it may be concluded that the CA up to level of 1.5% in diet may have positive effect on growth performance of growing rabbit. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21246 J. Bangladesh Agril.

Fifteen castrated male goats (12.97±1.46 Kg) aged between 12 and 13 months were used to study the effect of different levels of concentrate supplementation on growth performance and nutrient digestibility in Black Bengal goat under stall feeding. The feeding trial was continued for a period of 75 days where goats were supplied at the rate of 158g DM/kgW.75 /day. The animals were assigned into five dietary treatments: A (Only dal grass as sole feed), B (15% DM from concentrate + 85% DM from dal grass), C (20% DM from concentrate +80% DM from dal grass), D (25% DM from concentrate + 75% DM from dal grass), E (30% DM from concentrate + 70% DM from dal grass). Digestibility of all nutrients was gradually higher (P<0.01) from A to E. Total live weight gain of goats of group A was statistically lowest (P<0.01) than those of other groups. There was also significant difference (P<0.01) among the treatment groups E, D, C and B. Live weight was gradually increase due to gradual increase of concentrate from B to E. Nitrogen balance, carcass yield and net profit of treatment group E was highest (P<0.01) then D, C and B than A. Green grass do not fulfill the appetite and nutrient requirements as a sole feed. Concentrate supplementation is undoubtedly essential to fulfill the nutrient requirements and concentrate can be supplemented upto 30% of required DM to obtain the best result.DOI: http://dx.doi.org/10.3329/bjas.v40i1-2.10789Bang.

In a study that lasted for 120 days, 20 weaned Yankasa ram lambs aged 6 months and weighing between 10.5 and 14.5kg with an average of 12.75kg were offered a basal Digitaria smutsii hay diet at 2% of body weight. This was supplemented with a concentrate mixture made to supply 14.6% crude protein and 2.6 Mcal ME per kg and offered to treatment groups A, B, C and D at 1, 2, 3, and 4% of body weight respectively. There were five replicates and the animals were fed individually. Results indicated that the differences in Average Daily Gain was significant (P<0.05) between all the treatments; the value increased with increased level of feeding. The cost of effecting one unit of live weight increase was not significantly different (P<0.05) between treatments, A, B, and C, but it was significantly lower (P<0.05) than for treatment D. The low growth response of lambs fed the concentrate at 1% of body weight and the higher cost per unit gain of lambs offered the supplement at 4% of body weight suggested that concentrate supplementation at 2 and 3% of body weight was adequate for optimum liveweight gains in the Yankasa sheep breed.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

Recent genetic improvement has developed pigs with maximum potential for protein deposit at higher weights; however, their optimal slaughter weight still needs to be determined. The objective of the study was to evaluate live performance, carcass traits, and economic viability of 417 Agroceres PIC pigs slaughtered with 100, 115, 130, and 145kg live weight. Pigs were reared in pens with 10-11 barrows and gilts each, offered a feed allowance of 2.8kg/pig/day until the following slaughter weights (SW): 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, and 143.90±1.24. There was no interaction between sex and SW (P>0.05). Backfat thickness, fat area, and loin eye area linearly increased with SW (P<0.001; R2: 70.12-77.44%), and carcass yield increased in a quadratic manner (P<0.001; R²=24.66%). Lean yield was not affected (P>0.05), and feed conversion ratio (R²=43.29%) linearly worsened with SW (P<0.001), but the effect of SW on live production cost (R$/kg) was quadratic, with the minimum point at 134.8kg. It was concluded that, under the applied management, increasing SW results in larger amount of lean tissue with no change in its yield and little effect on growth performance.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Positive Effect

On the basis of the "Komarova" farm (Magadan, Magadan region), the effect of introducing a new non-traditional component feed additive of plant origin into the diets of young cattle was studied. The research was carried out during the stall period. For the experiment there were taken four groups of animals (14-16 months of age) divided at random in accordance with the genotype into control and experimental groups of ten animals each. The first two groups (control, experiment) included purebred Holstein bulls, the other two – hybrids of the 1st generation (1/2 Holstein × 1/2 Herefords). For the experimental groups, the main diet was supplemented with a component feed additive consisting of cedar elfin (Mountain pine) flour and lichens (alpine cladonia (Cladonia alpestris), Icelandic cetraria (Cetraria islandica)). The results of the experiment has shown that the feed additive, consisting of 120 g of cedar elfin needle flour and 50 g of lichen flour (80% of Cladonia alpestris and 20% of Cetraria islandica), has a positive effect on the intensification of metabolic processes in the animals. The digestibility of crude protein increased by 1.29-4,19 g (1.7-5.6 %); that of the organic matter – by 6.65-8.90 g (11.0-14.3 %); NFE (nitrogen-free extracts) – by 7.80-9.18 g (14.14-15.70 %). An increase in the digestibility of feed nutrients had a positive effect on an increase in live weight gain by 0.60-3.0 g (1.35-5.93 %). An increase in feed conversion was 0.24-6.8 MJ (0.20-6.74 %); feed protein – by 0.02-0.09 g (1.22-6.17 %). Crossbred bulls turned out to be more responsive to changes in the ration of feeding and showed better results in all studied parameters. The effectiveness of using the additive is due to the fact that the raw material for the production is obtained from wild plants growing in nature in sufficiently large volumes. They do not require significant costs for harvesting and preparation for feeding.
