The objective of this study was designed to test whether supplementation of the diet with arginine (Arg) or glutamine (Gln) or their combination influences the production, organ weights and humoral immune response of broilers. A total of 432 one-day-old male Ross 308 broiler chickens were divided into 6 treatment groups: control, Arg-0.5%, Arg-1%, Gln-0.5%, Gln-1% and Arg-0.5%+Gln-0.5%. Drinking water and feed were provided ad libitum. On day 18 of the experiment 50% of chickens in each treatment group were immunised with bovine serum albumin. Ten and 21 days after immunisation blood samples were collected to determine the anti-albumin IgY titre, interleukin 6 (IL6) and interferon gamma (IFNG) and to measure the weight of the liver, spleen, bursa of Fabricius and thymus. Arg or Gln supplementation of the diets influenced neither the production nor the organ weights until 18 days of age. Between 18 and 39 days of age both Arg (0.5% and 1%) and Arg + Gln supplementation improved the feed conversion ratio (FCR) by 3.7%, 6.3% and 4.9%, respectively, while Gln-1% worsened it by 15%. Immunisation slightly (−0.79%) depressed the body weight gain of broilers fed the control diet, which was significantly improved by both Arg (0.5 or 1%) and Arg + Gln supplementation. Immunisation increased the weight of the spleen, bursa and thymus and decreased that of the liver. Supplementation with 1% Gln depressed (−5.13%) the body weight gain of the immunised chickens but strongly stimulated the immune response. Supplementations with Arg and Gln did not influence the IL6 and IFNG level of the blood; however, on day 10 after immunisation these two parameters showed a negative correlation with each other. Regarding production, organ weights and immunity, Arg supplementation should be recommended in the grower phase, while Gln supplementation can be useful in pullets raised for egg production, where a good immune response to vaccinations is an important factor.

This study was conducted by Krishi Vigyan Kendra Jharsuguda, Odisha under National Innovations on Climate Resilient Agriculture Project in 2019-2020 in the operational villages Bhoimunda and Tharkaspur of Jharsaguda district of North-Western Odisha, India. A total of 300 unsexed brooded chicks, breed Vanaraja, were provided to the farmers under the project and were randomly distributed into three treatment groups (100 birds in each treatment group) with ten replications in each group, having ten birds in each replicate. The study was undertaken for a period of 7 months, from September, 2019 to March, 2020. The study started with birds of 4th week of age and continued up to 28th week of age. Vanaraja birds of group I were let out for foraging with no supplementation, in group II birds were provided with fresh Azolla @ 200 g per bird along with foraging and birds of group III were given commercial feed @ 50 g per bird along with foraging. Weekly body weight gain upto 16th week and egg production upto 28th week were recorded. The benefit cost analysis was also evaluated. The result of this trial indicated that supplementation of azolla in instrumental in increased body weight gain along with higher egg production with better Benefit Cost ratio. Therefore, it can be concluded that feeding of Azolla to poultry birds under backyard condition @ 200 g per day per bird may be highly effective method to get more profit. Under the prevailing situation of change in climatic condition, backyard poultry is a good insurance against crop loss and feeding of azolla to backyard birds will further strengthen the economic status of farmers.

In the present feeding trial, responses of laying hens, kept at high ambient temperature, to various dietary ratios of linoleic acid (LNA) to α-linolenic acid (ALA) and vitamin A levels on performance and egg characteristics were evaluated. A total of 360, 40-wk-old, Leghorn laying hens were fed on diets with various combinations of canola oil and linseed oil to achieve LNA to ALA dietary ratios of 20:1, 10:1, 4:1, 2:1, 1:1 and 1:2, each supplemented with 3000 IU or 10000 IU vitamin A/kg of diet. The diets were fed in a 6×2 factorial Completely Randomized Design that continued for 12 weeks. Feed intake, weight gain, egg production and egg quality traits were recorded during the trial. Decreasing dietary LNA to ALA ratio in the diet affected negatively (P<0.05) on body weight gain and yolk percentage in laying hens. While, feed intake, hen-day and hen-housed egg production, feed conversion ratio (FCR) per dozen of eggs and shell quality remained unaffected (P>0.05) by dietary treatments, with the exception of FCR per kg eggs, egg weight and egg-shell thickness which responded significantly (P<0.05) to various dietary treatments. Although the dietary ratio of LNA to ALA of 4:1 or less could produce eggs by the hens with desirable quantities of n-6 and n-3 poly unsaturated fatty acids – that are characteristics of functional diets – the performance of laying hens in terms of body weight gain and egg-yolk percentage was slightly compromised.

Growth, survival and egg production performance and profitability of exotic chicken breeds were evaluated under small-scale chicken producers in urban and peri-urban areas of Bahir Dar City from 2018 to 2019. Data were collected using semi-structured questionnaires, monitoring and field observation. Thirty-three small-scale chicken enterprises (30 from urban and three from peri-urban areas) were included in this study. All questionnaire data were analyzed using SPSS Version 20. The monitoring data was analyzed with ANOVA using the general linear model (GLM) procedure of SAS version 9.0. The monitoring result revealed that the growth performance of chicken significantly varied with respect to breeds and production systems of producers. Sasso T44 had higher daily body weight gain (10.66 ± 0.03 g) and total body weight gain (1642 ± 5.02 g) within 22 weeks of age in the urban areas. The mean egg production for Bovans Brown at the age of six months was 124.8 ± 4.10 eggs. The annual mean egg production performance of Bovans Brown was 239.63 ± 4.32. The overall mortality rate of all exotic chicken was 6.5%. Despite many constraints, small-scale chicken production was profitable. Seasonal disease outbreaks, shortages of feed and housing problems were the major constraints of small-scale chicken producers. The growth performance and survival rate of exotic chicken was promising, but the egg production was low. Therefore, the management practices of small-scale chicken enterprises in the study area should be improved.

The post-molting performance of 360 female Japanese quails was assessed using five molting methods including feed restriction along with supplementation of dietary levels of aluminum sulfate (AlSO4) and zinc oxide (ZnO) with two concentrations of 0.15% and 0.3%. None of the parameters studied were positively influenced by a single molting method. Body weight gain and feed efficiency were positively affected by higher concentration of ZnO while feed consumption was positively influenced by higher concentration of AlSO4. Similarly high feed efficiency was attributed to higher concentrations of both ZnO and AlSO4. On other hand body weight gain and feed efficiency were negatively influenced by 0.15% ZnO while egg production was worst by 0.15% AlSO4. As each of the molting method had different influence on the tested parameters and none of them could apply individually with perspective of better performance therefore the combinational use of molting methods is recommended according to the focused parameter

Amino Acid Balance

Diets containing up to 11% of rapeseed meal protein were fed to individually caged White Leghorn laying birds. Egg production, feed intake and body weight gain were less for birds fed rapeseed, rather than soybean meal. The reduction in body weight gain was associated with a reduction in carcass fat content, and an increase in carcass protein and moisture contents. Liver fat was also less for birds fed rapeseed meal. Results from amino acid supplementation studies indicated that the reduction in carcass fat deposition of laying birds fed RSM may be involved with dietary amino acid balance.

The production of biomass and antibacterial extracellular products by Lactobacillus casei subsp. casei CECT 4043 was followed in both batch and in realkalized fed-batch cultures. Enhanced concentrations of biomass and antibacterial extracellular products were obtained with the use of the latter fermentation technique in comparison with the batch mode. The culture obtained by fed-batch fermentation was mixed with skim milk and used to prepare a probiotic feed for weaned piglets. To test the effect of the potentially probiotic culture of L. casei on body weight gain, feed intake, feed conversion efficiency, and on fecal coliform counts of piglets, two groups of animals received either feed supplemented with the probiotic preparation or avilamycin for 28 days. The control group was fed nonsupplemented feed. At the end of the administration period (day 28), the groups receiving probiotic and avilamycin exhibited the highest average body weight gain values, although the mean feed intake and feed conversion efficiency values were not different among the groups (P &gt; 0.05). For the entire experimental period (42 days), the control group exhibited the lowest feed intake value, the probiotic group exhibited the highest feed conversion efficiency value, and the antibiotic group exhibited the highest body weight gain (P &lt; 0.05). Interestingly, no significant difference in body weight gain was observed between the probiotic and the control groups by day 42 (P &gt; 0.05). Fecal coliform values decreased (although not significantly) by day 28 in the three groups. However, the mean counts returned to pretreatment levels by day 42 in all groups.

SUMMARYThree varieties of triticale (TL-238, TL-257 and TL-319) bred by the Plant Breeding Department of Punjab Agricultural University were studied for nutrient composition and metabolizable energy (ME) content for egg-type chicks. A feeding trial was also conducted to study the suitability of triticale as a replacement for maize in conventional high- and low-cereal diets for different classes of egg-type chickens.The crude protein contents of TL-238, TL-257 and TL-319 were respectively 13·4,14·4 and 2·1%. Corresponding values for starch content were 51·5, 49·2 and 54·3%, respectively. ME in triticale varieties closely followed the trend of starch content. Accordingly TL-319 was higher in ME (13·58 MJ/kg D.M.) than TL-238 and TL-257 (12·91 and 12·49 MJ/kg D.M. respectively). There were no significant differences in body-weight gain or in food conversion of chicks fed diets containing different varieties of triticale. The substitution of triticale for maize in a conventional high-cereal diet improved growth and food conversion of starter chicks. In a low-cereal diet, however, triticale had an adverse effect on the growth rate and food conversion of starter chicks. At the end of 18 weeks of age, the differences in body-weight gain, food conversion and efficiency of protein utilization by chicks on all the treatments were not significantly different (P > 0·05). Results of the production phase showed that egg production, egg mass, food conversion and energetic efficiency were significantly (P < 0·05) improved by feeding triticale.
