“…Overall, the locally sourced breeds had lower mortality rates (brooding 7.3%, growing 8.2%, and laying 20.5%) than the foreign-sourced breeds (Brooding 21.3%, growing 8.7%, and laying 24.2%) which suggests that the locally sourced breeds were more adaptable to the environment than the foreign breeds. High mortality rates are reportedly associated with weakened immune systems, resulting from high levels of temperature-induced stress and inability of animals to efficiently thermoregulate (Al-Awadi et al, 1995;Furlan and Macari 2002;Mashaly et al, 2004;Mumma et al, 2006;Perreira et al, 2010). According to Ajakaiye et al (2011) and Tao and Xin (2003), high mortality, as influenced by heat stress, also depends on the physiological state and adaptability of the breed to its prevailing environmental conditions.…”

Background Availability of appropriate genetics is important for the development of smallholder poultry (SHP). The biological potential of improved dual purpose chicken germplasms was evaluated in Nigeria. Methods A total of six breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso, and Shika-Brown) were tested on-station, in deep litter houses at two test centres (Public and private facility) for 504 days. Birds were fed ad libitum for the first 140 days after which restricted feeding was practised. Result Lowest and highest hatchability of eggs set was 55% (FUNAAB Alpha) and 89% (Sasso), respectively. At 140 days, male live weights were 200%-300 % higher than the local chickens (975 g) except Shika-Brown (152%) and Fulani (135%). Lowest (p < 0.05) age at first egg was 119 days for Shika-Brown and 120 days for FUNAAB Alpha and Kuroiler. Highest hen-housed egg production was 192 for Shika-Brown, and feed intake per dozen eggs was lowest (p < 0.05) for Shika-Brown (2.9 kg) and FUNAAB Alpha (2.9 kg). Mortality rate of the locally sourced breeds (Fulani, FUNAAB Alpha, Noiler, and Shika-Brown) was significantly lower (p < 0.05) than the foreign-sourced breeds (Kuroiler, Sasso) during brooding, growing and laying. Conclusion Results from this study identified FUNAAB Alpha and Noiler as being more suitable for dual-purpose functions (egg and meat), while Sasso and Kuroiler (meat) and Shika-Brown (egg) were observed to be better suited for single purpose functions. These findings could guide the introduction of smallholder poultry-specific hybrid germplasms for the development of the smallholder poultry production systems in Nigeria.

“…Figure 1a shows that the months with minimum temperature higher than 19.2 ºC corresponded to the hot season in the region of Bastos, indicating that some management strategies, such as housing layers to have to onset of lay during the cold season, lowers the probability of high mortality. In addition to their physiological status, housing layers with onset of lay during the hot periods of the year may result in worse performance and high mortality (Al-Awadi et al, 1995).…”

Layer mortality due to heat stress is an important economic loss for the producer. The aim of this study was to determine the mortality pattern of layers reared in the region of Bastos, SP, Brazil, according to external environment and bird age. Data mining technique were used based on monthly mortality records of hens in production, 135 poultry houses, from January 2004 to August 2008. The external environment was characterized according maximum and minimum temperatures, obtained monthly at the meteorological station CATI in the city of Tupã, SP, Brazil. Mortality was classified as normal (≤ 1.2%) or high (> 1.2%), considering the mortality limits mentioned in literature. Data mining technique produced a decision tree with nine levels and 23 leaves, with 62.6% of overall accuracy. The hit rate for the High class was 64.1% and 59.9% for Normal class. The decision tree allowed finding a pattern in the mortality data, generating a model for estimating mortality based on the thermal environment and bird age.

“…The feed efficiency ratio in physical terms was found to be 2.47, 2.36 and 2.34, respectively and the feed efficiency ratio in economic terms was found to be 0.75, 0.70 and 0.63, respectively in groups i, ii and iii. The feed efficiency ratio in physical terms was found to be 2.77 by Kurtaslan (1997) by Al Awadi et al (1995). in the study by horne and Bondt (2003), it was reported that the average feed efficiency ratio was 2.09 in germany, 2.11 in France, 2.14 in England, 2.20 in Poland, 2.30 in Ukraine, 2.14 in Brazil and 2.21 in india.…”

In this study, different capacity laying hen farms in Afyon province, which are of a considerable importance in the laying hen farming in Turkey, were compared in the terms of performance, including feed consumption, production cost and profitability per chick and egg and the most profitable farm size was determined. Data were obtained by conducting a questionnaire research with 75 farmers. Laying hen farms were divided into three groups according to their sizes and were analyzed accordingly. It was found that higher capacity farms had a higher egg yield and a better feed efficiency. It was also found that farms with a higher capacity were advantageous in terms of the technical and economic criteria. Results showed that as farm capacity increased, production cost per hen decreased and net profit per hen increased. It was found that profit margin was negative for group I and positive for group II and III, and profit margin increased as the farm capacity increased.
