Content Analysis of Agricultural Issues Reported in Two Nigerian Daily Newspapers
This study used two widely read Nigerian newspapers (Punch and Guardian) to assess the extent of daily newspapers involvement in disseminating agricultural information. Samples of the newspapers between 2007 and 2010 were analysed for daily reportage, space allocation and types of stories published. All data collected were analysed using simple descriptive statistics. Results showed that 70%, 78.8%, 66.3% and 60% of the newspapers evaluated did not report any agricultural issues in 2007, 2008, 2009 and 2010 respectively. Among those that reported agricultural issues, majority reported 1-2 stories per day representing 21.3%, 28.8%, 25% and 36% of total sample size in 2007, 2008, 2009 and 2010 respectively. Mean column inch allocation were 27.43, 10.77, 35.89 and 27.52 for 2007, 2008, 2009 and 2010 respectively. Total column inch allocation to the publication of agricultural issues in 2007, 2008, 2009 and 2010 were 2194.29, 861.54, 2870.94 and 2201.52 respectively for all eighty (80) newspapers sampled in each year. Finally, except in 2008, the subject that attracted the highest reportage was health implications of the consumption of agricultural commodities. Judging by previous and current trends, the authors concluded that newspapers are not likely to make significant contribution to the dissemination of agricultural information for enhanced agricultural production
Effects of reducing postpartum re-mating time- period on reproductive performance of the doe
Rabbits being induced ovulators can be rebred
within 24 hours after parturition. However,
reproductive efficiency and the doe’s physiology
can be affected by postpartum re-mating interval.
This study evaluated the effects of reducing the
re-mating interval after parturition on sexual
activity, fertility, gestation, parturition and litter
characteristics using 90 does. Three groups of
crossbred (New Zealand White Ă— Chinchilla) does
were used in a randomized complete block design.
Does were re-mated 1-9, 10-20 and 21-28 days
after parturition in the dry and rainy seasons in
Ayetoro, Ogun State, Nigeria. Acceptance of
mating decreased with increasing postpartum re-
mating interval. Conception rate was highest in the
21-28 days group (98.8%) and lowest in the 10-
20 days group (68.4%). Gestation length was
significantly shorter (p<0.05) in the 10-20 days
group (30.7 days), than 1-9 days group (31.6
days) and 21-28 days group (31.7 days). Litter
size and weight at birth were not significantly affected. Kit’s mortality was lower (p<0.05) in
the 21-28 days group (25.6%) compared to 10-20
days group (57.4%) and 1-9 days group (58.8%).
Litter weight (total and alive at birth) was
heavier (p<0.05) during the rains (295.9 and
294.9 g) than dry season (250.1 and 243.3 g).
Reducing the re-mating interval after
parturition enhanced sexual activity. Fertility was comparable in does re-mated 1-9 and 21-28
days after parturition.Les lapins étant des ovulateurs incités peuvent
reprocréer en moins de 24 heures après la
parturition. Cependant l’intervalle de récopulation
postpartum peut influer sur el efficacité de
reproduction et sur la physiologie de la lapine.
Cette étude a évalué les effets de la réduction de
l’intervalle de ré-accouplement après la naissance
sur l’activité sexuelle, la fertilité, la gestation, la
parturition et les caractéristiques des petits, en
utilisant 90 lapines. Trois groupes de lapines de
race croisée (New Zealand White × Chinchilla) ont
été utilisés dans un bâtiment découpé en cabines
de dimensions prises au hazard. Les lapines ont
été ré-accouplées entre 1 à 9, 10 à 20, 21 à 28
jours après la parturition les saisons sèches et
pluvieuse à Ayetoro, dans e’ Etat d’Ogun au
Nigeria. L’acceptation de récopulation a décru
avec l’accroissement de l’intervalle de récopulation
postpartum. Le taux de conception Ă©tait le plus
élevé dans le groupe de 21 à 28 jours (98,8%)
et le plus bas dans le groupe de 10 Ă 20 jours
(68,4%). La durée de gestation était consi-
dérablement plus courte (p<0,05) dans le groupe
de 10 Ă 20 jours (30,7 jours) que dans le groupe de 1 Ă 9 jours (31,6 jours) et que dans le groupe
de 21 Ă 28 jours (31,7 jours). La grosseur et le
poids des petits à la naissance n’étaient pas pour
autant affectés. La mortalité à la naissance était
plus basse (p<0,05) dans le groupe de 21 Ă 28
jours (25,6%) par rapport aux groupes de 10 Ă 20
jours (57,4%) et de 1 Ă 9 jours (58,8%). Le poids
des petits (total et vivants Ă la naissance) Ă©tait plus
lourd (p<0,05) pendant les pluies (295,9 et
294,9 g) que pendant la sécheresse (250,1 et
243,3 g). La réduction de l’intervalle de récopulation
après parturition a augmenté l’activité sexuelle. La
fertilité était comparable chez les lapines ré
accouplĂ©es dans les groupes de 1 Ă 9 et de 21 Ă
28 jours après parturition
