“…Thus, it appears that FUNAAB Alpha birds are more suitable to the environmental settings in Kebbi and Nasarawa compared to Imo. The present findings are consistent with the submission of Kassa et al (2021) that breed-environment interaction could influence the phenotypic expression of traits. Similar genotype by location interaction effect on growth traits has Frontiers in Genetics frontiersin.org 10 been documented in improved indigenous and tropically adapted chickens (Ajayi et al, 2020;Guni et al, 2021b).…”

“…The observed genetic effect on survivability is consistent with the findings of Ajayi et al (2020). Similar observations have also been made on chickens in Nigeria (Ademola et al, 2020), Ethiopia (Kassa et al, 2021), and Tanzania (Guni et al, 2021b).…”

“… Birhanu et al (2022) reported that the use of improved tropically adapted chicken breeds increased the production and productivity of birds in smallholder flocks in sub-Saharan Africa. This eventually paved way for the generation of more income, while contributing to food security, social and ecological resilience ( Dumas et al, 2016 ; Kassa et al, 2021 ). These improved chicken breeds have also been reported to be more preferred than the indigenous (native, unimproved) chickens by smallholder farmers in terms of market-oriented performance indices ( Yakubu et al, 2020 ; Birhanu et al, 2022 ).…”

The impact of COVID-19 pandemic on smallholder farming households (SFH) includes increased poverty, and loss of livelihoods. Provision of livestock to SFH is a helpful intervention to mitigate this impact. This study provided a total of 150 smallholder poultry farmers, randomly selected from three states (Kebbi, Nasarawa, and Imo) in Nigeria, with ten 5-week-old chickens (mixed sexes) each, of either FUNAAB Alpha or Noiler chicken genetics. The improved, dual-purpose chickens were evaluated for growth performance (GP), survivability and profitability. The birds were managed under semi-scavenging production system. Body weight, mortality, and cost of production (COP) were recorded every 4 weeks until 21 weeks of age. Profitability was a function of the COP, and the selling price for live-birds (cocks). Body weight of Noiler (1,927 g) birds was not significantly (p > .05) higher than FUNAAB Alpha (1,792 g) at 21 weeks. Agroecology and genetics had significant (p < .05) effects on GP and survivability. Survivability of FUNAAB Alpha was higher (p < .05) than Noiler, with Nasarawa (81%–96%), having the highest (p < .0001) survival rate compared to Imo (62%–81%), and Kebbi (58%–75%). At 21 weeks, the number of cocks and hens differed significantly (p < .05) within the states (Imo: 2.4 ± .2 and 5.4 ± .3; Kebbi: 2.6 ± .2 and 5.5 ± .3; and Nasarawa: 2.9 ± .2 and 5.8 ± .3). Nasarawa (NGN 7,808; USD 19) ranked best for profitability, followed by Kebbi (NGN 6,545; USD 16) and Imo (NGN 5,875; USD 14). Overall, this study demonstrates that provision of improved chickens to vulnerable SFH in Nigeria holds great potential for economic growth, and resilience during emergencies, such as the COVID-19 pandemic.

“…However, a comparison of the body weight of the native chickens in this study with that of other Thai native chickens showed that the chickens in this study had body weights 122 g higher than that of Chee chickens [ 9 ] and 88 g higher than that of Leung Hang Khao chickens [ 13 , 14 ]. In addition, the body weights were higher than those of native chickens in Korea [ 25 ], chicken strains in Egypt [ 26 ], Venda chickens of South Africa [ 29 ], and native chickens of Ethiopia [ 30 ]. These results indicate that this study’s method of genetic improvement of Thai native chickens is valid.…”

To ensure that any new technology developed within an experimental station is appropriate to the community’s needs and compatible with the existing systems, on-site farm research is an important component in examining the effectiveness of agricultural research. The present study examined the growth performance and genetics of Thai native chickens under conditions typically experienced by farmers on smallholder farms (on-site farms) compared with at an experimental unit (on-station). There were 1694 Thai native chickens (Pradu Hang dum) used in this experiment, and they were divided into 613 chickens for the on-station and 1081 chickens for the on-site farm experiments. The individual chicken data included the birth weight (BW0) and body weight at 4, 8, 12, and 16 weeks of age (BW4, BW8, BW12, and BW16, respectively), ADG from 0–4, 4–8, 8–12, 12–16 weeks of age (ADG0–4, ADG4–8, ADG8–12, ADG12–16, respectively), and breast circumference at 8, 12, and 16 weeks of age (BrC8, BrC12, BrC16, respectively). A multiple traits animal model and a selection index were used to estimate the variance components, genetic parameters, and breeding values of growth traits. The results showed that the body weight, average daily gain, and breast circumference at 8, 12, and 16 weeks of age of Thai native chickens raised on-station were higher than those raised on-site at the farm among mixed-sex and sex-segregated chickens, while the birth weight and body weight at four weeks of age (BW0 and BW4) and ADG from 0–4 weeks of age (ADG0–4) were not significantly different (p > 0.05). The heritability estimates of body weight, average daily gain, and breast circumference in the chickens raised at the on-site farm and on-station were moderate to high, with on-station values slightly higher than on-site farm values. The heritability estimates of body weight were 0.236 to 0.499 for the on-site farm, and 0.291 to 0.499 for on-station. For average daily gain, the heritability estimates were 0.274 to 0.283 for the on-site farm and 0.298 to 0.313 for on-station; meanwhile, and for breast circumference, the heritability estimates were 0.204 to 0.268 for the on-site farm and 0.278 to 0.296 for on-station. Both phenotypic and genetic correlations among and between growth traits were positive and ranged from low to high values. The top 20% of the estimated breeding values and selection indices in the on-site farm and on-station experiments showed that the body weight at eight weeks of age (BW8), ADG from 4–8 weeks of age (ADG4–8), and breast circumference at eight weeks of age (BrC8) should be used as selection criteria for Thai native chicken breeding programs. In conclusion, the genetic parameters and breeding values in on-station experiments showed that the breeding program by selection index for improving growth performance is valid. Therefore, to implement such a breeding program in an on-site farm, an intensive or semi-intensive farm system should be considered to minimize the effect of genotype-environment interaction.

There are various studies on AGP substitute feed additives that provide many options for solutions related to the problem of maintaining gut health. Therefore, it is necessary for a fundamental evaluation of the use of some feed additives on the response of livestock. The purpose of this engineering practice is to find best solution for growth promoter antibiotics (AGP) alternatives that can be effectively used in laying hens Farm. Trials of several probiotic and organic acid product supplementation were carried out on 21,000 laying hens of the HyLine Brown strain aged 50 weeks for 1 month. Tested products were protected probiotic powder (OGC), liquid probiotics (PBL) and liquid organic acids (APK), these products were evaluated based on production egg quality and cost feasibility studies. Data on egg production and egg quality were analyzed using ANOVA and then actually compared between treatments with Tukey's test (p<0.05) and also compared based on production standards from producers/breeders. The trial results showed that the use of liquid probiotics (PBL) resulted in the highest egg production and egg weight, organic acid products (APK) resulted in higher distribution of large eggs and more efficient feed conversion, the use of protected probiotic powder (OGC) resulted in highest haugh unit. The economic feasibility study shows that organic acid products (APK) produce the highest return on investment value. The concluded showed that organic acid product (APK) will be effectively used in laying hens Farm. Key words: egg quality, laying hen, organic acid, probiotic
