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.

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,99±0,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%.  (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.99±0.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.

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.

Thirty male Holstein calves were utilized in a 2 × 3 factorial experiment designed to compare rapeseed meal (cv. Candle) and soybean meal as protein supplements and 0, 10, and 20% levels of protected lipid as a form of supplemental energy for starter rations. The six rations were fed free choice from 21 to 70 days of the experiment with whole milk fed at 10% of body weight from 0 to 42 days. Starter intake was similar for the two protein sources but significantly less for the ration containing 10% protected lipid compared to either the 0 or 20% levels. Body weight gain was faster for calves fed the starter containing 20% protected lipid compared to those fed the 10% level. Efficiency of feed conversion was greater for calves receiving protected lipid. There were no differences between protein source in dry matter intake, body weight gain, efficiency of feed conversion, apparent dry matter digestibility or dressing percent. Plasma glucose and percent hematocrit were significantly lower and percent kidney fat significantly higher for calves fed starter rations containing soybean meal. The relative availability of copper was reduced significantly when soybean meal or 20% protected lipid formed part of the starter diet. It was concluded from this study that Candle rapeseed meal was a suitable source of supplemental protein for calf starter diets and that the inclusion of protected lipid improved feed conversion of calves from 43 to 70 days of age.

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.

Thirty two bred rats were allotted to two diets to investigate the influence of non-addition or addition of 1000 ppm KCN to cassava — soybean diets on thiocyanate concentrations, tissue rhodanese activity and performance parameters. KCN caus­ed a non-significant (P>0.05) depres­sion in body weight gain but had no effect on weights of liver, kidney and placenta, nor on number and weight of 19 day old foetus. High (1000 ppm) KCN level caused a significant (P<0.05) increase in urinary thiocyanate excretion of thiocyanate. It however had no marked effect on serum protein bound 'iodine, ammiotic fluid thiocyanitte, rhodanese activity of foetal and material tissues nor on foetal thio­cyanate concentration.

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 Impact

The aim of this work was to assess the impact of a total dietary replacement of extracted soybean meal (SBM) on body weight gain and pork quality. DanBred hybrid piglets were divided into four groups of 10 piglets each. Groups I (males) and II (females) were the control groups and fed a standardized SBM-based complete feed. The experimental groups III (males) and IV (females) were offered a diet in which the SBM was replaced with extracted rapeseed meal (RSM) and legume plants (pea and yellow lupin). After 83 days of fattening, the animals were slaughtered. Based on the collected data, the daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) were calculated. In addition, longissimus dorsi muscle was subjected to physicochemical analyses, including the basic chemical composition. All the analyses were performed in accordance with the applicable methodologies. As a result of this experiment, no interactions were found between the experimental factors (sex and diet). The replacement of SMB by legumes and RSM resulted in a significant reduction in the final body weight of growing–finishing pigs. Additionally, daily body weight gain was reduced between 35–83 days, and through the whole fattening period (0–83 days). Most pork meat quality parameters were not affected by the type of mix feed and sex (p > 0.05). The fattening pigs that were fed legume seeds and RSM had significantly reduced fatness (p > 0.05) compared to the control pigs. In males, there was also a significantly lower pH45 (p < 0.05). It can be concluded that feeding pigs with diets containing legume plants and extracted rapeseed meal does not affect the pork meat quality, but it may worsen the body weight gain.

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
