This paper examined the effects of nano mineral supplementation of diets on the growth of pigs. The total of 180 pigs used for this study were classified into 4 experimental groups and one control group. The results showed that the weight of pigs at the beginning and the end of the experiment was insignificantly different between experimantal and control groups. The same daily gain weight was observed between experimental and control groups. However, the feed conversion ratio (FCR) of four experimental groups I, II, III and IV is 3.00 ± 0.28, 2.95 ± 0.11, 2.85 ± 0.19 and 2.90 ± 0.24, respectively, that were lower than of the control groups, i.e. 3.17 ± 0.42. The mineral content of Fe, Cu, Zn and Mn in liver of pigs in all the experimental groups is lower than that in liver of pigs in the control group. In addition, the amount of Fe and Zn metal in urine and feces of the experimental groups is also lower than in the control group. The results of our study showed that the addition of nano minerals in diets for pigs not only reduced the feed conversion ratio in pigs, also decreased the amount of minerals releasing into the environment.

A feeding trial was conducted on 21 crossbred (Local×Friesian, Local×Sahiwal, Sahiwal×Friesian) calves of around one week age for a period of 70 days with the objective of evaluating effects of probiotic on growth performances of calves. Calves were selected and distributed equally into three groups maintaining equal sex ratio in each group, namely the farm practice (FP), control and probiotic groups. The calves were fed on milk as 12% of their live weight up to 14 days and then 10% milk of their live weight up to 70 days of age and wheat bran was supplied to the calves from 50th day at the rate of 250g/calf. The calves of probiotic group werefedaprobiotic mixture containing lactic acid bacteria (LAB) at 0.5 g /d. The data of feed intake and growth for all groups were recorded up to 35 days and then up to 70 days for probiotic and control groups. The calves under probiotic group were achieved 82.8% and 74.5% higher gain (P<0.05) than that of FP and control group, respectively and feed conversion ratio was observed significantly (P<0.05) better in probiotic group (1.83) than that in FP (3.41) and the control group (3.50) up to 35 days of trial. However, no significant differences were found in average live weight gain and feed conversion ratio between probiotic and the control groups (1.99 vs 2.07, respectively) up to 70 days of the trial. Average counts of E. coli were lower in probiotic group than that in the control and FP. The incidence of diarrhoea in probiotic fed group was found 3 and 13 times lower compared to FP and the control group, respectively. Bangladesh J. of Livestock Res. 21-25: 89-102, 2018

The Laetiporus sp. is a fungal species that is traditionally used for medicinal purposes. This study investigated the effects of the Laetiporus sulphureus fermented product (FL) as a feed supplementation on the antioxidant activities, the intestinal Tight Junction (TJ) mRNA expression, and the intestinal morphology of broiler chickens. Four-hundred one-day-old male broilers (Ross 308) were randomly allocated to five experimental diets: (1) a corn-soybean meal basal diet (control), (2) a basal diet replaced with 5% Wheat Bran (5% WB), (3) a basal diet replaced with 10% WB (10% WB), (4) a basal diet replaced with 5% FL (5% FL), and (5) a basal diet replaced with 10% FL (10% FL). The FL-supplemented groups exhibited a better feed conversion ratio in the overall experimental period compared to the WB and control groups. The serum antioxidant profiles of 35-day-old broilers showed that, compared to the control and 10% WB groups, the 5% FL supplementation group had a significantly increased superoxide dismutase activity, while it down-regulated the concentration of malondialdehyde in the serum (p < 0.05). The assessment of selected antioxidant gene expression showed that the 5% FL group significantly elevated heme oxygenase-1 and nuclear factor erythroid 2–related factor 2 expression, compared to the control and WB groups (p < 0.05). Furthermore, both of the FL supplemented groups had a significantly higher expression of glutathione peroxidase and catalase, compared to that of the WB and control groups in the jejunum (p < 0.05). The TJ mRNA expression in the jejunum showed that 5% FL significantly elevated the zonula occludens-1, claudin-1, and mucin-2 expression (p < 0.05), while 5% and 10% FL supplementation significantly improved OCLN expression in both the jejunum and ileum, compared to control group (p < 0.05). The intestinal morphology of 35-day-old broilers showed that a 5% FL supplementation significantly increased the villus height in the ileum and jejunum, compared to the WB and control groups (p < 0.05). Moreover, the 5% and 10% FL supplementation groups had a significantly higher villi:crypt ratio in the ileum, compared to the WB and control groups (p < 0.05). To conclude, FL supplementation improved the antioxidative status, the TJ mRNA expression, and the intestinal morphology, and it was accompanied by a lowered feed conversion ratio in broilers. Finally, 5% supplementation had the overall best results in improving the antioxidant status, TJ mRNA expression, and intestinal morphology of broilers.

The objective of the study is to compare the practical results with the predicted results by Crossbreeding Effects (CBE) software on pig crossbred based on daily gain, backfat thickness and feed conversion ratio. Another purpose of this study is to predict those three traits among some expected hybridization. This research was conducted on pig farm at Binh Thang Research and Development center from 2013 to 2017. In this study, for each pair of purebred Duroc and Pietrain, Duroc and Landrace, Pietrain and Landrace, twelve hybridizations were analyzed, nine unhybridizations were predicted by CBE software. The results showed that there was no significant difference between the predicted and actual data. With some unhybridization crossbred , the predictions showed high reliability (P<0.05). Based on the predicted data of CBE software , some traits of the crossbred animals would not be improved, therefore, it was not necessary to conduct these hybridizations

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.

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.

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.

THE EFFECT OF PARTLY SUBSTITUTION OF DIET WITH WHITE CHINESE CABBAGE (Brasscia pekinensia L) WASTE PRODUCT ON BIOLOGICAL PERFORMANCE OF BROILER CHICKEN The present study was conducted to characterize the effect of white Chinese cabbage (Brasscia pekinensia L) waste product as an alternative feed source for broiler chicken.  The experiment was conducted at Faculty of Animal Husbandry’s experimetal station for 21 days using 60 MB-202 broiler chicken. The experiment was started at 21 days of age and terminated at 42 days of age. Birds were allocated to 20 experimental battery cage, 3 birds in each cage. Completely Randomized Design (CRD) with 5 treatments and 4 replications was employed to analyze experimental data. Treatment diets were formulated as follow: R0 = 100% basal diet and 0% white Chinese cabbage waste product; R1 = 95% basal diet and 5% white Chinese cabbage waste product; R2 = 90% basal diet and 10% white Chinese cabbage waste product; R3 = 85% basal diet and 15% white Chinese cabbage waste product; and R4 = 80% basal diet and 20% white Chinese cabbage waste product. Parameters measured were: 1) daily feed consumption; 2) daily gain; and 3) feed conversion ratio (FCR). The results of the study during which feed consumption (138,09-141,57g), weight gain (64,95-68,53g), and feed conversion (2,07-2,12). The results showed that partly substitution (up to 20%) of basal diet with white Chinese cabbage waste product gave non significant (P > 0.05) effect on feed consumption, daily gain, and feed conversion ratio (FCR) of broiler chicken. It can be concluded that white Chinese cabbage waste product can be used up to 20% feed gives good results on broiler performance.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P &lt; 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P &lt; 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P &lt; 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

Abstract Improved genetics in commercial pig production have resulted in larger litter sizes. However this has increased the prevalence of compromised pigs exhibiting inferior birthweights, weaning weights, and lifetime performance. This study aimed to determine the effects of increased sow lactation feed intake on growth of low and average birthweight piglets until 10 wk of age. Low (Low BW; &lt;1 kg) and average (Av BW; 1.3–1.7 kg) birthweight animals were reared in uniformly weighted litters comprising 14 piglets on a foster mother offered either a low (Low FA; max 7.5 kg/d) or high (High FA; max 11 kg/d) feed allowance over a 28- ± 1-d lactation. Piglet performance was monitored from birth until 10 wk of age. Sows offered a High FA consumed 42.4 kg more feed on average than those offered Low FA, resulting in a greater derived milk yield (P &lt; 0.05). Animals of Av BW remained heavier than Low BW pigs throughout the trial (P &lt; 0.05). Piglets reared by High FA sows were heavier at weeks 3, 4, 5, and 7 (P &lt; 0.05) but not week 10 (P &gt; 0.05). Growth rate of piglets relative to their birthweight was significantly greater for Low BW piglets than those of Av BW during lactation (P &lt; 0.001). Piglets reared by sows offered a High FA expressed greater relative growth preweaning (P &lt; 0.05); however, postweaning relative growth for piglets reared on sows offered a Low FA was greater (P &lt; 0.05) suggesting compensatory growth. Neither birthweight nor sow feed allowance significantly affected preweaning mortality (P &gt; 0.05). However, Low BW animals on sows with a High FA recorded half the preweaning mortality of Low BW pigs on sows with a Low FA. During week 1 of lactation, Av BW litters recorded a greater total suckling duration compared to Low BW litters (P &lt; 0.05) but there was no difference in suckling frequency (P &gt; 0.05). During week 3 of lactation, High FA litters displayed a significantly lower suckling frequency (P &lt; 0.05) yet a greater total suckling duration (P &lt; 0.001). Average daily gain was greater for Av BW pigs during weeks 4–7 (P &lt; 0.001) but no difference was recorded between weeks 7 and 10 (P &gt; 0.05). Average daily feed intake was greater for Av BW pigs throughout the nursery period (P &lt; 0.05) but feed–conversion ratio did not differ compared to Low BW pens (P&gt;0.05). In conclusion, offering sows a High FA increased weaning weight of all animals; however, birthweight was the major determinant of postweaning performance.
