Increase in egg production, egg quality and immunity of local chicken resulted by cross-breeding

Abstract

A series of study aimed to improve egg production, egg quality and immunity resulted by cross-breeding with Arab chickens and laying chickens has been observed on 400 chickens of 5-month old of hens was used and treatment was divided into 2 groups: medium and heavy type hens. Randomized Block Design was used and hens were fed on a laying diet contained 18% of crude protein content and 2900 kcal/kg of metabolism energy. Parameters observed were the number of daily eggs (hen/day), clutch, egg weight, egg shape, shell thickness, Haugh unit (HU) and the total percentage of egg production during one production cycle. Immunity was observed by thymus size and time of thymus regression. The results showed that daily and total egg production, clutch spacing, egg weight, egg shape, hemp thickness, Haugh unit (HU) of egg in both heavy and medium type were significantly higher than pure local chicken. However, all the parameters of egg production and egg quality on the type of weight were significantly higher than the light type. In terms of immunity, time of thymus regression on crossbreed hen type occurred at 14-16 weeks of age. It concluded that crossbreeding between local chicken increased egg production and egg quality on derivatives of local chicken. It was also informed that the immunity of derivatives of local chicken resulted by crossbreeding against endemic diseases was better than that of in natural breed chicken.

Species identification and prevalence of gastrointestinal helminths in Indonesian native chickens, and its impact on egg production

“…The average HDP of Lurik, Wareng, Lokal Putih, and Ranupane chickens at the age of 7 to12 months (along six months of chicken raised) was 45.80%; 34.36%; 36.39%, and 35.87%, respectively (Table 3). This value was lower than Sartika et al (2011) study based on the Mx gene of native chicken (60-64%) and Yaman et al (2020) on crossbred Indonesian native chicken by average 47.80%. However, it was higher than Aseel chicken of Indian native chicken (36.23%) at 70 weeks (Haunshi et al 2011).…”

Evaluation of Ruta graveolen, coriander and basil seed extracts as natural additives on productive performance, blood profiles and egg quality of White Leghorn layers

“…As Sigolo et al, (2021) indicated, different plant extracts were delivered to broiler in drinking water and they had a significant impact on the feed intake of the animal. Body weight gain and egg production in T4 were not significantly different compared to control that could be the feed intake similarity between these treatments (Yaman et al, 2020).…”

Forecasting Layer Egg Production as Animal Source Food for Protein to Reduce Stunting in West Java, Indonesia

“…In addition, it can assist the farmers in constructing or expanding poultry farms. Research and development in the poultry sector can lead to innovations that can enhance egg production, such as new breeds with higher egglaying capacities (Yaman et al, 2020), improve feed formulations and develop disease prevention and control strategies (Akintunde et al, 2015).…”
