Abstract

This study aimed to  investigate the effect of green tea waste, fibrolytic enzymes (xylanase and cellulase) and phytase  supplementation in layer  diets on   performance and egg quality. The experiment was assigned in a 2×3 factorial arrangement by completely randomized design.  Factor A consisted of two types  of diets: a) a basal diet without any green tea waste   and b) a basal diet with 1% of green tea waste.  Factor B consisted of three  levels of enzymes: a) level 0X, no enzyme supplementation; b) level 1X, a combination of fibrolytic enzymes,  24,000 FAXU xylanase and 100 ECU cellulase, and 1,000 FTU phytase; and c) level 2X, combination of fibrolytic enzymes,  48,000 FAXU xylanase and 200 ECU cellulase, and 2,000  FTU phytase.  One hundred  and ninety- two   Roman  Brown hens, aged 52 weeks, were randomly distributed to  six   groups and four replications. Layer hens were fed commercial diets with green tea waste and fibrolytic enzymes added on top as assigned in the treatment. The results showed that  green tea waste   significantly  increased (p<0.05) egg production, egg mass, feed conversion,  and Haugh unit.   In addition, green tea waste  tended  to affect (p=0.07) TBAs value.  Furthermore, the enzyme level significantly decreased  (p<0.05) feed intake and TBAs value.  In conclusion, the supplementation of 1% of green tea waste and 2X enzymes can  improve feed  conversion   and  the antioxidative  property of  eggs.

Abstract

Liver X Receptor Alpha (LXRα) is a nuclear receptor that play a crucial role in regulating of gene involvedin lipid metabolism. The aim of this research was to identify polymorphisms and association of LXRα gene with charateristic of carcass, meat quality and fatty acid composition in ducks using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). A total sample of 98 Cihateup ducks consisted of 57 females and 41 males with age 12 weeks were used in this study. Product size is 661 bp amplicons. The genotype genes frequencies in CC, GC and GG were 0.21, 0.55 and 0.23 respectively. The chi-square test revealed that LXRα gene (g.3575 C>G) in exon 2 was in Hardy-Weinberg equilibrium. A SNP of LXRα gene in region g.3575 C>G was significantly associated (P<0.05) with duck meat quality and fatty acid content. Several parameters have significant affect (P <0. 05) on meat quality in the breast meat weight, carcass percentage and head percentage, while associated fatty acids were saturated fatty acids (SFA) such as palimitic acid (C16:0); γ-and unsaturated fatty acids (UFA) such as linolenic acid (C18:3n3); cis 11 eicosenoic acid (C20:1) and 11.14 cis-eicosedenoic acid (C20:2). In could be concluded that LXRα gene might be useful as genetic markers to select and produce meat with desirable unsaturated fatty acids.

Abstract

The aims of this investigation were characterization, demonstration of the antibiogram pattern and detection of the pathogenicity of Clostridium perfringens (C. perfringens) strains isolated from broiler chickens in Damietta governorate, Egypt. A total of 357 samples representing 202 intestinal contents and 155 liver samples from freshly dead broiler chickens were collected from 18 broiler farms. Isolates of C. perfringens were identified morphologically, microscopically, and biochemically. Forty-seven C. perfringens isolates were recovered, which represented 20.3% of the intestinal contents and 3.8% of the liver samples. The toxins and virulence genes of C. perfringens were investigated using polymerase chain reaction. All of the toxigenic C. perfringens strains were type A and carried netB, tpeL, cpe, and plc genes. The in vitro antibiogram of C. perfringens strains revealed 100% sensitivity to gentamycin and levofloxacin and 100% resistance to nalidixic acid and ceftriaxone. The isolated C. perfringens strains were highly pathogenic and induced signs and lesions of necrotic enteritis as well as 43.3% mortalities in 20-day-old chicks. In conclusion, C. perfringens is an important pathogen that affects broiler chickens due to the presence of virulence genes and the pathogenicity in the inoculated birds.

Abstract

Broiler meat is the second world's most consumed meat, and the increase in consumption by 2027 is forecasted to be near 35 kg/capita/year. Brazil ranks third in broiler production globally and is the world's largest exporter of chicken meat. To reach proper rearing conditions, broiler farms need to meet good practices of husbandry and welfare. The present study aimed to develop a performance classification model using data mining to evaluate broiler farmers based on detailed flock housing and performance information. The input dataset from 49 broiler farms from a cooperative in Northeastern Brazil was organized with details on the housing characteristics, rearing environment, management, and performance data from flocks. We also added the cooperative technical classification retrieved from the housing conditions and the production index. The input classification had weights attributed to each housing feature. The output variable (target) was defined as the performance classification (PC) index. The dataset was processed using Rapidminer® software using 80% of training and 20% for implementing the random forest algorithm. The prominent variables in classifying the performance were the feed conversion, the daily weight gain, the productivity index, and the cooperative classification criteria. The developed model pointed out a way to auto-classify farms and allow the cooperative to evaluate the farmers' production based on the broiler production and management practices. It was possible to create 'If-Then' rules that enable appropriate decisionmaking by broiler farmers to comply with good practices' norms.

Abstract

The objective of this study was to evaluate single nucleotide polymorphisms (SNP) in the 3'UTR region of CAPN1 gene by direct sequencing technique in beef cattle and its influence on growth and meat quality of the contrast mode ultrasound image in Bali cattle. The numbers of beef cattle used were Bali cattle (n=52 heads) which compared to purebred Belgian Blue (n=30 heads), Limousine (n=14 heads), Wagyu (n=7 heads), and PO (n=10 heads). Genetic diversity data were obtained from calculations by PopGen 1.32 software. Ultrasound imaging of the thoracic longissimus dorsi muscle in Bali cattle was carried out between the 12 − 13 ribs, and the sonogram was analyzed by Image-J NIH software. The result shown that 3’UTR of CAPN1 gene was found in six discovery SNPs that polymorphic in Bali cattle, they were g.15284 C>T, g.15347 T>G, g.15525 G>A, g.15853 G>A, g.15905 G>A, g.15915 G>A and Indel mutation was polymorphic in Bali cattle, Belgian Blue, Limousine, and PO. There was no association between these SNPs and growth traits. However, SNP g.15525 G>A was significantly associated (P<0.05) with a backfat thickness (BFT) in Bali cattle. In conclusion, the CAPN1 gene in Bali cattle is a candidate for Marker Assisted Selection (MAS) related to meat quality.

Abstract

This study was conducted to assess the happiness of small-scale dairy cattle farmers based on subjective well-being conditions. The research was conducted in July-October 2020 using a survey method in the Malang Regency of East Java Province. Analysis units were 145 small-scale dairy cattle farmer households purposively selected with less than 30 heads of dairy cattle ownership and have managed their livestock farming for more than five years. Data collection was conducted through interviews about three dimensions of happiness including life satisfaction, affection, and the meaning of life. The three dimensions were divided into 19 indicators to calculate the Happiness Index. The ten Life Satisfaction indicators produced a Life Satisfaction Index of 7.43 (Happy), consisting of a Personal Life Satisfaction Index of 7.26 (Happy) and a Social Life Satisfaction Index of 7.85 (Happy). The three Affection indicators produced the Affection Index of 7.29 (Happy). The six Meaning of Life indicators produced the Meaning of Life Index of 7.44 (Happy). The Happiness Index of small-scale dairy cattle farmers in East Java was 7.43 and classified as "Happy".

Abstract

The aim of this study was to compare the external and internal egg quality of three layer strains namely Bovan Nera, ISA Brown and FUNAAB Alpha. One hundred and fifty eggs sampled from 120 birds per strain from 35 to 45 weeks of age were used for the study. Data collected were analysed using one way analysis of variance in a completely randomized design. ISA Brown had significantly (P<0.01) the heaviest eggs on the average at 45 weeks, followed by Bovan Nera and FUNAAB Alpha. The egg quality characteristics of Bovan Nera and ISA Brown were similar but significantly (P<0.05) superior to FUNAAB Alpha in egg width, egg volume, egg surface area and albumen weight. FUNAAB Alpha was significantly (P<0.05) the most superior in yolk weight only. Three principal components (PC1, PC2 and PC3) were produced from each strain after principal component analysis and varimax rotation. Estimation of breeding values based on the three principal components could be used for the selection and improvement of egg quality variables in each strain instead of isolated traits.

Abstract

The study investigated the effect of sprouted papaya seed meal (SPSM) on physiological conditions, intestinal bacteria and meat quality of broilers. A 390 broiler chicks were distributed to T0 (control feed), T1 (feed with 2.5% papaya seed meal [PSM]), T2 (1% SPSM), T3 (2.5% SPSM), and T4 (5% SPSM). Blood, intestinal digesta and meat were obtained at day 36. Feeding 2.5% PSM lowered (P<0.05), but SPSM up to 5% had no effect on daily gain. PSM reduced (p<0.05) feed intake, but not SPSM. Feed efficiency was lower (P<0.05) in T4. Feeding 5% SPSM increased (P=0.06) bursa of fabricius. T1, T3 and T4 had lower (P=0.09) heterophils. Mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were lower (P<0.05) in T4. Cholesterol to high-density lipoprotein (HDL) ratio of PSM and SPSM was lower (P<0.05) than control. SPSM at 2.5% increased (P<0.05) serum HDL. PSM-fed birds had lower cholesterol (P=0.07), triglyceride (P=0.09) and lowdensity lipoprotein (P=0.09). PSM or SPSM decreased (P<0.05) serum total protein, albumin and globulin. PSM and SPSM reduced (P<0.05) creatinine. Alanine aminotransferase was reduced (P<0.05) with SPSM at 1 and 2.5%. Ileal lactic acid bacteria to coliform ratio in PSM and SPSM was greater (P<0.05) than in control. Ileal coliform was lower (P=0.08) in PSM and SPSM. PSM reduced (P=0.08) saturated fatty acids, while 1 and 2.5% SPSM increased (P=0.09) unsaturated fatty acids contents of meats. In conclusion, SPSM improved immune competence, blood lipid profile and gut bacterial population of broilers.

Abstract

The aim of this study was to analyze of Sauropus androgynus (SA) leaves powder supplementation on kampung hens reproductive traits. Forty kampung hens aged 4-5 months were distributed randomly into 4 treatments with 10 replications. A completely randomized design (CRD) was used as research design. Samples were placed in individual postal-litter system cages. The four groups were fed diets supplemented with 0, 4, 8, and 12% SA leaves powder for 8 weeks, respectively. The supplementation of SA leaves powder affected serum steroid hormone progesterone (P4) metabolite (P < 0.05), serum steroid hormone estradiol-17β (E2) metabolite concentration and a number of medium follicles yield significantly (P < 0.01). Concentration levels of serum steroid hormone E2 and P4 metabolites were 1 to 5-fold and 2 to 14-fold higher in supplemented hens than non-supplemented, respectively. In conclusion, supplementation of SA leaves increased serum steroid hormone E2 and P4 metabolite concentration, number, and weight of follicles. The role of precursor contained in SA leaves powder detected on Indonesia kampung hen’s reproductive traits.

Abstract

An experimental study was carried out to evaluate the implication of early fattening of Kejobong goats by improving feeding quality on methane production and meat production. Sixteen goats (8 young and 8 mature) were raised for 4 months study period. Nested design was used in this study, with young and mature as a nest factor, and diet (G7C3: 70% grass and 30% concentrate and G3C7: 30% grass and 70% concentrate) as the treatments. The main parameters observed were DMI, BWG, carcass (CWG) and meat weight gain (MWG), and methane emission. The results showed, the young goat fed G3C7 was higher than that fed G7C3 in DMI. The BWG’s of goats fed G3C7 were higher than those fed G7C3, but there was no difference between ages in BWG. The FCR of young goat fed G3C7 was lower than that fed G7C3. The DMI of mature goat was higher than young goat, but there were no differences between the ages in DM digestibility, carcass weight and meat weight gain. The young and mature goats fed G3C7 was significantly lower than that of G7C3 in methane emissions per unit of BWG (0.28 vs 0.40 and 0.36 vs 0.53, respectively), in methane emissions per unit CWG (0.60 vs 0.93 and 0.79 vs 1.47, respectively), and methane emission per unit MWG (0.89 vs 1.42 and 1.16 vs 2.19, respectively). It can be concluded that fattening young Kejobong goats by improving feed quality is more environmentally friendly than fattening the mature ones.
