CROSSING BETWEEN SINAI CHICKEN STRAIN AND SOME OTHER LOCAL LAYER CHICKEN STRAINS

An observational study was undertaken to measure odour and dust (PM10 and PM2.5) emission rates and identify non-methane volatile organic compounds (NMVOCs) and odorants in the exhaust air from two tunnel-ventilated layer-chicken sheds that were configured with multi-tiered cages and manure belts. The study sites were located in south-eastern Queensland and the West Gippsland region of Victoria, Australia. Samples were collected in summer and winter on sequential days across the manure-belt cleaning cycle. Odour emissions ranged from 58 to 512 ou/s per 1000 birds (0.03–0.27 ou/s.kg) and dust emission rates ranged 0.014–0.184 mg/s per 1000 birds for PM10 and 0.001–0.190 mg/s per 1000 birds for PM2.5. Twenty NMVOCs were identified, including three that were also identified as odorants using thermal desorption–gas chromatography–mass spectrometry/olfactometry analysis. Odour emission rates were observed to vary with the amount of manure accumulation on the manure belts, being lowest 2–4 days after removing manure. Odour emission rates were also observed to vary with diurnal and seasonal changes in ventilation rate. Dust emissions were observed to increase with ventilation rate but not with manure accumulation. Some NMVOCs were identified at both farms and in different seasons whereas others were observed only at one farm or in one season, indicating that odorant composition was influenced by farm-specific practices and season.

Background: Acetyl-CoA Carboxylase Beta (ACACB) plays a key role in fatty acid oxidation and was known to be involved in production of very-long-chain fatty acid and other compounds needed for proper development. This gene is mainly expressed in the tissues of heart, muscle, liver and colon. It chiefly involved in the production of malonyl-coA, a potent inhibitor of carnitine palmitoyl transferase I (CPT-I) enzyme needed in transport of long-chain fatty acyl-coAs to the mitochondria for β-oxidation.Methods: The present study was conducted to explore the expression pattern of the ACACB gene in breast muscle tissue during pre-hatch embryonic day (ED) 5th to 18th and post-hatch (18th, 22nd and 40th week of age) periods of White leghorn (IWI line) by using Quantitative real-time PCR (qPCR). Then, fold change of ACACB gene expression was calculated.Result: Our study showed that the ACACB gene expression was down-regulated during embryonic stages from ED6 to ED18. The gene expression was also down-regulated during adult stages i.e. on 22nd and 40th week of age. This result indicated that the initial expression of the ACACB gene is required for embryo development and during adult periods, low gene expression leads to the less fat deposition in muscle of layer chicken. Finally, it can be concluded that there was a differential expression pattern of the ACACB gene during the pre-hatch embryonic and post-hatch adult periods to mitigate varied requirements of lipids during different physiological stages in layer chicken.

Marketing Chain

Small and Medium Enterprises (SMEs) are one of the economic strength pillars of the community because their management involves the community directly, both in providing production facilities, labors, and its marketing chain. However, some SMEs failed in the middle of their business road or are unable to develop. This condition also occurs in SME of Al-Barkah Laying HenFarm. The purpose of implementing this program is to increase business capacity both from the production and management aspects of the Al-Barkah layer chicken business. The method used in overcoming these problems and achieving goals is by providing direct training, guidance, and application of science and technology. All activities were carried out jointly by the owners and employees of UKM Partners, guided by the implementation team. After implementing the program, the SME partner now: (1) understands and can conduct business planning; (2) can carry out business effectiveness and efficiency; (3) can increase understanding of the importance of order in the livestock business process; (4) Understands the importance of hygiene and cage sanitation; and (5) can increase the chicken health, egg production, and farmer income. The conclusion from the program implementation is that the Al-Barkah layer chicken business has increased production by 15% and an increase in business efficiency by 12% as a result of improvements in production and business management aspects.
