In ovo injection of cinnamon or clove alters the physiology and growth of broilers in a hot tropical environment.

A study was conducted to evaluate the influence of in ovo feeding of clove and cinnamon on broilers. The experiment used 700 broiler (Ross 308) hatching eggs that were incubated at the recommended temperature of 37.8 °C.

Research Note: Responses of broiler chickens to in ovo feeding with clove and cinnamon extract under hot-humid environments.

An experiment was carried out to evaluate the responses of broiler chickens to in ovo injection of aqueous extracts of clove and cinnamon under a hot-humid environment. The study involved the use of seven hundred hatching eggs from broilers (Ross 308) which were incubated with the use of standard protocol (37.8°C).

Environmental stress and livestock productivity in hot-humid tropics: Alleviation and future perspectives.

Tropical environments are characterized by persistently high temperature and relative humidity and the harsh environmental conditions pose a serious limitation on the optimal performance of the animals raised in this region. Heat stress causes deleterious effects on welfare, immunology and physiology of farm animals with a resultant impact on their productivity as the use of body resources is re-organized and the metabolic priorities of animals shift away from production, growth, health and reproduction. It is imperative to understand the mechanisms involved in the thermoregulation of animals under tropical conditions in order to develop appropriate strategies for their improvement.

Evaluation of sweet citrus peel supplement in water on performance and ileal microbial count of broiler chickens.

The effect of supplementing drinking water with sweet citrus peel powder (SCPP) on the performance, ileal microbial count, and relative weight of organs of broiler chickens reared in a tropical environment was investigated. Ninety-six (96) 1-day-old Ross broiler chickens, after brooding, were randomly allotted into four treatment groups: T1 (control) received drinking water without SCPP, while birds in T2, T3, and T4 were given water supplemented with 2, 4, and 6 g of SCPP per liter of water, respectively. Each treatment was replicated three times with eight birds per replicate in a completely randomized design.

Evaluating the health risk of metals (Zn, Cr, Cd, Ni, Pb) in staple foods from Lagos and Ogun States, Southwestern Nigeria.

The study evaluated the health risk of metals in commonly consumed staple foods from Lagos and Ogun states, southwestern Nigeria. One hundred and thirty-three food samples were collected and analyzed for Zn, Cr, Cd, Ni, and Pb using atomic absorption spectrophotometric method. Data collected were analyzed for simple descriptive and inferential statistics using SPSS for Windows.
