A survey study was conducted to analyze the reproductive and productive performances of four indigenous chicken breeds under different rearing system. Six villages located in Eastern Cape, South Africa were used for the study from July 2017 to June 2018. Data on clutch per year (CPY), hatchability (HATCH), egg per clutch (EGC), survivability at 10-12 weeks (SURV), egg per year (EPY), recovery period (RP), average age at production (AA), duration of rearing (DR), mortality, egg laying length (EGL), natural brooding period (NBP) and natural incubating period (NIP) were obtained from Seven thousand, five hundred and thirty eight (7538) indigenous chicken. Potchefstroom Kooekok is observed to be a good egg producing breed with 15.11±0.25eggs per clutch. Venda breed possess good mothering ability (hatchability) and high survivability with 86.03±0.31days and 82.70±0.26 days respectively. Naked Neck is known to be more prone to diseases with least (survivability) 60.08±0.25days. Village was positively correlated with EGC and HATCH, EGY and SURV at p≤0.01 and p≤0.05 respectively. Rearing system was positively correlated with EGC. Rearing system was positively correlated at p≤0.05 on EGC than CPY, HATCH, EGY and SURV. Breed and village interactions were significant at p≤0.05 on RP, AA, DR, EGL, NBP and NIP. Therefore, productive and reproductive traits of indigenous chicken differ across different rearing systems, breeds and villages.

Abstract. The genetic diversity at major histocompatibility complex (MHC) in indigenous chicken breeds of India (Ghagus and Nicobari) in comparison with the White Leghorn (WLH) breed was investigated by genotyping the MHC-linked LEI0258 marker. Altogether 38 alleles and 96 genotypes were observed among three breeds. The observed and effective alleles were highest in Ghagus (23, 8.3) followed by Nicobari (14, 3.2) and WLH (10 and 2.2) breeds. The size of alleles ranged from 193 to 489 bp in Ghagus, 193 to 552 bp in Nicobari and 241 to 565 bp in the WLH breed. The number of private alleles was also highest in Ghagus (18) followed by Nicobari (8) and WLH (5) breeds. The most frequent allele was 261 bp in WLH (66 %), 343 bp in Nicobari (50.4 %) and 309 bp in the Ghagus (28.15 %) breed. Observed and expected heterozygosities were highest in Ghagus (0.83, 0.88) followed by Nicobari (0.58, 0.68) and WLH (0.53, 0.54). The genetic distance (Nei) between Ghagus and Nicobari breeds (2.24) was higher as compared to that of Ghagus and WLH (1.23) and that between Nicobari and WLH breeds (0.89). Association analysis revealed significant influence of MHC alleles on body weight, egg production in Ghagus and WLH breeds and antibody titres to Newcastle disease vaccine in the Nicobari breed.

Chicken Breeds

In Ethiopia, chicken production plays an important role in providing human food consumption, growth of domestic products, and creating employment opportunities. Despite their importance, the production and reproduction performance of chickens in the country is under expectation owing to the gap between low productive indigenous and low adaptive ability of highly productive chicken breeds. By considering this, the present paper aims to deliver, synthesize, and summarize the compiled information on the current status of indigenous and highly productive chicken breeds. Currently, there are several highly productive chicken breeds available in Ethiopia. Among these, Rhode Island Red, Fayoumi, Potchefstroom Koekoek, Sasso, Bovan Brown, Issa Brown, and Leghorn are being kept under various husbandry systems. Besides, indigenous chicken ecotypes such as barley plumage color, red plumage color, white plumage color, and black plumage color have been characterized in the country. However, the average annual egg production of indigenous and highly productive chicken breeds did not exceed 60 and 250 eggs, respectively. On the other hand, the meat production ability of indigenous chickens is limited as cockerels and pullets may reach 1.5 and 1.05 kilogram live weight at 6 months of age, respectively. Concerning the husbandry system, a majority of owners supplied feed to chickens on the ground and water in plastic containers while scavenging is being the common feeding system in most parts of the country. Furthermore, the majority of the owners are using no separate housing system and treat their chickens traditionally. Thus, awareness should be emphasized on enhancing the improvement of chicken husbandry systems for better production and reproduction performance.

The study was conducted in midland and lowland agro-ecological zone of North western zone of Tigray, Ethiopia. Two districts were selected purposively based on their potential exotic chicken breed production. Out of the total chicken producers in the study area 264 farmers, 132 from each of the two districts were selected randomly using systematic random sampling methods. It was conducted in cross sectional survey data from 264 respondents in 2016. Its aim was to assess the contribution of producing exotic chicken to dietary diversity of the rural households with 24 hours recall method. The study examines the study area is characterized in a low dietary diversity mainly defined by starchy staples (grains, condiments, oil or fats) at the expense of protein sources (meat, fish, fruits, vegetables, eggs). The result also indicates that there is a higher probability of the exotic chicken producers groups to move from a medium dietary diversity status to a high dietary diversity status as compared with indigenous chicken producers. Based on the study result, there is possibility to improve dietary diversity and income of the households through introduction and dissemination of exotic chicken breeds to rural households. Hence, governmental and non-governmental organizations should help in intervention of exotic chicken breed to the farm households by giving different incentives.

The efficacy of diatomaceous earth (DE) on growth rate, egg production and on increasing feed conversion efficiency in deep litter raised layer hens was evaluated. The study was conducted at Mukono Zonal Agricultural Research and Development Institute (MUZARDI) in Uganda. Worms were collected from fresh intestines of indigenous chicken obtained from Kalerwe chicken market near Kampala. The DE was mined in Pakwach (formerly Nebbi) district in Northern Uganda. Chickens of the Lohmann Brown breed raised on deep litter were studied. At 7 weeks the birds were divided into 5 treatment groups, A, B, C, D and E each composed of 40 birds. Groups C, D and E were given an oral dose containing 250 embryonated eggs of A. galli while groups A and B were not infected. The chicks were weighed; and subjected to feeding trials as arranged below: A – Non-infected birds on DE (4%) supplemented diet; B –non-infected birds on neither piperazine (a conventional de-wormer) nor DE; C – infected birds on DE supplemented diet; D – infected birds on piperazine; and group E – infected birds on neither DE nor piperazine applied. Fecal samples were collected and analysed in the laboratory biweekly at week 16 till week 22 respectively for fecal egg counts. In a subsequent experiment, day-old layer chicks from Lohmann Brown strain but different from those used in earlier experiments, were used to assess the effect of DE on egg production. At 17 weeks of age the 420 were divided as follows: 6 treatment groups each having 7 replicates and each replicate having 10 birds. This study showed that DE can be used successfully in growing pullet diets to correct nutritional mineral imbalance since it supplies more than 14 trace elements and other elements. Diatomaceous earth also enables pullets to cope with Ascaridia galli load; and 2% DE supplementation did not have significant improvement on egg production as compared to no supplementation at all. However, reduction in egg production was experienced when supplementation with levels of DE higher that 2% was applied. Results from biweekly fecal analyses showed significant differences in fecal egg counts (p<0.05); and treatment by group (p<0.05).

The improvement of productivity of indigenous chicken is a long desire in the country. Present research is a part of the long-term selection program being undertaken to evaluate the carcass characteristics and expected response to selection of second generation (G2) of indigenous chicken under intensive management in Bangladesh. A total of 1643-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Desi (ND) were hatched in a two batches for this study. In second generation (G2), selection was practiced at 3 (three) stages of birds life, firstly and secondly at 8 and at 16 weeks of age, selection was performed on the basis of breeding value for 8 and 16 week body weight. Thirdly, at 40-week of age, on the basis of an index comprising the parameters of age at sexual maturity (ASM), body weight (BW), egg production (EP) and egg weight (EW). Improvement target of egg weight was to increase by 1g and improvement target of egg production rate was to increase by 2 % per generation. The main target was the mean body weight in H, ND and NN chicken has to be gone up from the initial eight-week body weight of 375, 342 and 331g to 500 g at eight weeks of age. At 8, 10 and 12 weeks of age, six birds from each genotype were slaughtered to analyze the meat yield traits. Slaughter data were analyzed in a 3(genotype)×3(slaughter age) factorial arrangement in CRD by General Linear Model (GLM) Univariate Procedure in SPSS Computer Program. Genotype and slaughter age had significant effect (p<0.001) on dressing percentage. Body weight at 8 weeks of age was expected to improve by 51.21 vs. 24.03; 37.74 vs. 15.47 and 26.26 vs. 9.65g; respectively for ND, H and NN males and females. In terms of body weight H genotype was superior and NN genotype was for dressing percentage. As a result of selection; EP, BW increased and ASM reduced in second generation than that of the foundation stock.Asian J. Med. Biol. Res. March 2017, 3(1): 66-71
