Effects of layer breeder age and reduced incubator oxygen concentrations on embryo development, hatching events, chick quality, embryonic mortality and hatchability of fertile eggs.

The combined effects of breeder age and oxygen (O) concentrations on embryo development, hatching events, chick quality, embryonic mortality and hatchability were investigated. A total of 900 hatching eggs of average weight of 53.85 ± 2.

In ovo toxico-pathological effects of medicinal plants used against coccidiosis on chicken embryos development and hatchability.

TOXICO-pathological effects of herbal plants have always been a major concern, but little information is provided on the toxico-pathological effects of medicinal plants used against coccidiosis. This study aimed to assess the histopathological effects of Carica papaya seeds (CPS), Azadirachta indica leaves (AIL), and Sarcocephalus latifolius root (SLR) used as coccidiostat in traditional poultry farms with various doses using the chick embryo model. A total of 420 Sasso breeder eggs at ED4 of incubation were inoculated with the extract of these plants following a 3×4 factorial design with 3 plant extracts (CPS, AIL and SLR) and 4 inoculation doses (0, 25, 50 and 100 mg/kg egg-weight).

The Anticoccidial In Vitro Effects and Antioxidant Properties of Several Plants Traditionally Used for Coccidiosis in Togo.

Coccidiosis is a parasitic disease that often affects livestock. Identifying plants with inhibitory effects on the development of the parasite could help in finding new natural treatments. This study aimed to evaluate the anticoccidial potentials of extracts from leaves (AILs), leaves (CMLs), seeds (CPSs), roots (SLRs), and leaves (VALs).

Effect of crossbreeding on growth performance, meat quality, and the economics of production of the pure and reciprocal crosses between the Sasso and Wassachie chickens.

The interplay between genetics and economics is important in understanding how crossbreeding can be harnessed to optimize sustainable poultry production, meat quality, and economic viability. This study was conducted to investigate the effect of crossbreeding on growth performance, meat quality, and production economics. A total of 451 unsexed day-old chicks were raised for 12 wk in a pure (Sasso X Sasso [SS]; Wassachie X Wassachie [WW]) and reciprocal cross (Sasso X Wassachie [SW]; Wassachie X Sasso [WS]) design.

effect of Soursop ( L.) leaf extract on hatching and post-hatch performance of Noiler chickens.

Pharmacological and nutritional benefits of plant leaf extracts can be harnessed to address the problem of poor chick quality, performance and high mortality, which affect both hatchery and farm managers. This study sought to evaluate the effect of Soursop leaf extract (SLE) on the hatching and post-hatch performance of Noiler chicks. A total of 640 fertile eggs were randomly distributed into four groups of five replicates: (0.

Antiviral potentials of garlic (Allium sativum) in poultry production: A mini review.

Poultry enterprise is challenged with high economic losses due to viral infections. The outbreak of such infections, including Newcastle disease, avian influenza, infectious bronchitis and infectious bursal disease, could undermine poultry performance leading to decreased meat and egg production. The potency of vaccines in recent times has dropped with the rise in the virulence of antigens, which can interrupt vaccination defence.

Use of Manihot esculenta leaves on physiological and production parameters of Sasso breeder hens.

Background: The world population is increasing, leading to competition between humans and animals for the use of farm produce. The use of non-conventional resources in poultry feed is increasingly being explored. Cassava (Manihot esculenta) have been studied in layers and broilers feed.
