Influence of a probiotic on broiler performance [PDF]
Revista Brasileira de Zootecnia, 2011 The objective of the present study was to evaluate the influence of a probiotic product (composition: Lactobacillus acidophillus (3.5 × 10(11) CFU), Streptcoccus faecium (3.5 × 10(11) CFU) and Bifidobacterium bifidum (3.5 × 10(11) CFU)) on broiler performance.

Poultry Science, 2020 Two experimental trials on commercial broiler (Ross-308) were conducted to evaluate the carryover effect of artificial insemination (AI) in parent flock (PF) kept in cages (C), and on floor (F) in comparison to natural mating (NM) in floored PF.

Influence of broiler strain cross and dietary protein on the performance of broilers
Poultry Science, 1998 The purpose of this experiment was to quantify the responses of two broiler strain crosses to different dietary protein levels on performance and carcass yields. Day-old broiler chicks from a high-yield strain cross (Ross x Ross 208) and a fast-growing strain cross (Peterson x Arbor Acres) were placed in floor pens on fresh pine shavings.

Performance of broilers on furazolidone additive
Nigerian Journal of Animal Production, 2021 One hundred and twenty Anak broiler chicks of both sexes were fed furazolidone (additive) in feed to study their growth/weight gain response. The birds were grouped into four, A, B, C, and D of 30 chicks each Treatments B, C and D were administered with furazolidone in feed at the following dosage rates: 0.008%, 0.004% 0.002% respectively.

The Effect of Temperature and Density on Broiler Performance
Poultry Science, 1968 Abstract STUDIES by Barrott and Pringle (1949, 1950), Ota and Garver (1954), Prince et al. (1960) and Howes et al. (1962) indicated that the optimum environmental temperature for growing broilers decreased to approximately 12.8° to 18.3° at 4 to 5 weeks of age.

The Effect of Brooding Temperature on Broiler Performance
Poultry Science, 1996 In response to the energy crisis of the 1970s, this laboratory recommended that initial brooding temperatures for broilers be reduced to 29.4 C from 32.2 or 35 C. Because environmental temperature has been implicated in the ascites syndrome, this work was conducted to see whether the recommended brooding temperature of 29.4 C the 1st wk, 26.7 C the 2nd
