The present study examined the comparative performance between Bovans Nera and other commercial pullet strains in Nigeria. This study was carried out in the pullet house at the Teaching and Research Farm of the University of Ibadan, Ibadan, Nigeria, from January to April, 2002. The experiment was carried out to compare the growth performance and profitability of Bovans Nera with three other commercial pullet strains, Bovans Godline, Lohmann White and Lohmann Tradition. All data collected were subjected to the analysis of variance using the SAS General Linear Model procedure. Differences between treatment means were separated using Duncans New Multiple Range Test. Profitability was assessed using net returns by subtracting costs (rearing pullet, feed and packaging excluding overheads and labour) from income (from egg sales and spent birds). The results showed that Bovans Nera was better in feed conversion ratio, feed efficiency (a greater weight gain per unit feed intake) and attained a greater weight and a better market value than the other pullet strains. There was a higher production cost for Bovans Nera when compared with other strains. However, Bovans Nera will give more returns on investment even when their eggs are translated to monetary terms. These differences can be attributed to variation in the genetic constitution of individual strains.

Abstract Two experiments evaluated the effects of feeding a new corn hybrid, containing an α-amylase enzyme trait, Syngenta Enogen Feed Corn (SYT-EFC), on feedlot performance and carcass characteristics at two locations. Experiment 1 utilized 300 calffed steers (298.5 ± 16.3 kg of BW) at the University of Nebraska–Lincoln Eastern Nebraska Research and Extension Center Mead, NE. Treatments were designed as a 2 × 2 + 1–factorial arrangement with factors consisting of 1) corn type (SYT-EFC or conventional [CON]) and 2) byproduct type (with or without Sweet Bran [SB]), or a BLEND of STY-EFC and CON without SB. In Exp. 2, 240 crossbred, calf-fed steers (287.6 ± 15.4 kg of BW) were utilized at the University of Nebraska–Lincoln Panhandle Research and Extension Center near Scottsbluff, NE. Steers were fed SYT-EFC, CON, BLEND, or CON with a commercial α-amylase enzyme supplement (CON-E). In Exp. 1, there was an interaction for ADG (P = 0.05) and G:F (P = 0.02). Steers fed SYT-EFC with SB had greater ADG and G:F than CON; however, in diets without SB, SYT-EFC and CON were not different resulting in a 10.1% change in G:F when steers were fed SYT-EFC in SB compared with CON and only 1.6% change between SYT-EFC and CON without SB. Energy values, based on performance data, resulted in a 6.5% and 8.3% change in NEm and NEg, respectively, for steers fed SYT-EFC and CON with SB and 1.6% change for both NEm and NEg for steers fed SYT-EFC and CON without SB. For the main effect of corn trait, steers fed SYT-EFC had greater marbling scores, fat depth, and calculated yield grade compared with CON (P ≤ 0.03). In diets without SB, there was no difference between SYT-EFC, CON, or BLEND for DMI, final BW, ADG, G:F, NEm, or NEg (P ≥ 0.35). In Exp. 2, cattle fed SYT-EFC, BLEND, or CON-E had greater final BW, ADG, and G:F than cattle fed CON (P ≤ 0.03). On average, NEm and NEg were 4.9% and 7.0% greater, respectively, for steers fed amylase enzyme treatments compared with CON (P ≤ 0.01). Hot carcass weights were greater in steers fed α-amylase treatments compared with CON (P &lt; 0.01). Feeding Syngenta Enogen Feed Corn, which contains an α-amylase enzyme trait, at both locations improved feed efficiency in finishing cattle diets containing WDGS or SB.

Introduction: This study describes the epidemiologic features and clinical course of children with blood transfusion-associated HIV infection (TAHI) in Ibadan, Nigeria. Methodology: All children diagnosed to have TAHI at the University College Hospital, Ibadan, were studied and compared with children who acquired HIV vertically using the pediatric HIV database in the hospital. Results: Transfusion-associated HIV infection accounted for 14 (2.3%) of the 597 children diagnosed to have HIV infection between January 2004 and December 2011. The mean age at diagnosis of TAHI was 10.2 years and that of vertically acquired HIV infection was 3.9 years ( P < .001). In 9 cases, blood transfusion took place in private hospitals and in 5 cases in public hospitals. Median interval between infection and diagnosis of AIDS was 84 months in cases with TAHI and 48 months in vertically acquired cases ( P = .542). Conclusion: Optimal blood safety practices are advocated for prevention of TAHI in Nigeria.

Genetic associations between feed efficiency, growth, and live ultrasound measured body composition traits were studied in purebred beef bulls of six breeds in Ontario bull test stations from 1991 to 2000. Feed traits included average daily feed intake (FI), feed conversion ratio (FCR), and residual feed intake [feed intake adjusted for production alone (RFIp) or production and backfat thickness (RFIb)]. Growth traits were average daily weight gain (ADG), mid-test metabolic weight (MW), hip height (HH), and scrotal circumference (SC). Body composition traits included ultrasound backfat thickness (BF), longissimus muscle area (LMA), and predicted percentage of intramuscular fat (IFAT). Bulls were measured every 28 d for weight and individual feed intake, and at the end of test for ultrasound body composition traits. Number of records per trait ranged from 2284 (FI) to 13 319 (ADG). Fixed effects of test group, breed and end of test age (within breed), and random effects of animal and herd of origin were modeled using REML bivariate analyses for all traits. Heritability estimates were moderate for all traits (0.30 to 0.55), except for IFAT (0.14). The genetic correlation between RFIp and RFIb was high (0.99) within breeds, but breeds ranked differently with respect to RFIp and RFIb. Genetic correlations of RFIb with ADG and backfat thickness were essentially zero, which indicate that selection on residual feed intake could be implemented to reduce feed intake and improve feed conversion without compromising growth or changing levels of subcutaneous fat. Key words: Central test, genetic correlation, heritability, residual feed intake

Awassi Lambs

Lasalocid is a polyether antibiotic derived from the fermentation of streptomyces lasaliensis used as a coccidiostat in sheep. There are varying literature reports on lamb growth rate and feed intake when lasalocid is included in the diet of feedlot lambs. While some reports have shown that lasalocid enhances feed efficiency in ruminants by decreasing feed intake and either maintaining or improving rate of gain others indicate that lasalocid did not have any effect on lamb growth rates or feed efficiency (Stobart et al., 1987). Also, when lasalocid was fed to Chios lambs, growth rate was increased but there was no improvement in feed conversion efficiency (Hadjipanayiotou et al., 1988). There are no published data in the literature relating to the use of lasalocid as a growth promoter in the Awassi breed of sheep fed complete diets and the purpose of this study was to investigate the effect of lasalocid with two levels of protein on the growth rate and feed efficiency of weaned male and female Awassi lambs.

This article describes a new idea about using Bifidobacteriumsp isolates as an alternative to antibiotic growth promoters, based on the ability of Bifidobacteriumsp isolates, which have the potential as a probiotic in laying hens. This study aims to prove that Bifobacteriumsp could improve production performance, including feed conversion ratio, feed efficiency, and nutrient intake (feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter). A total of 150 laying hens at 25 weeks of age were divided into three groups (P0: control, P1: 0.1% antibiotic growth promoters, P1: 0.05% Bifidobacterium spp. probiotic) and fed on a basal diet containing 2750 kcal/kg metabolizable energy and 18% crude protein for four weeks. The different supplementation to the basal diets showed significant differences (p<0.05) on feed conversion ratio, feed efficiency, feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter intake among the treatments. However, feed intake, feed conversion ratio, crude protein intake, crude fiber intake, lipid intake, and organic matter intake were lowest in the group fed with 0.5% of Bifidobacterium spp. The highest feed efficiency was obtained from the groups fed with 0.5% of Bifidobacterium spp, compared with the control and supplemented antibiotics growth promoters group. 0.5% of Bifidobacterium spp. supplementation to the diet of laying hens is beneficial for increasing feed efficiency and improving feed conversion ratio. The practical and theoretical significance of the results is that Bifidobacterium spp. can be used to improve production performance in laying hens.
