Summary

Using on-farm supplementation trials with a P rich block (Phos) and a salt block (Salt), deficiency of P in White Fulani cattle in Nigeria was investigated. There was some evidence, significant in some locations but nonsignificant overall, that P supplemented dams produced heavier calves and supported greater calf growth. Dam mean weight gains, 9 to 1 monthspre-partum were 6·9 kg/month on Phos (s.d.=5·0, n=50) and 3·8 kg/month on Salt (s.d.=4·7 n=54) (P>0·05). Overall least squares means of calf weights at 12 months were 105·2 kg (n=29, s.e. 9·3) on Phos and 91·5 kg (n=37, s.e. 6·3) on Salt (P>0·05). In animals below 2 years of age, mortalities were 6.8% on Phos and 13·6% on Salt (n=179, Chi-square P<0·01). No response to supplementation was observed in older and non-pregnant cattle.

Résumé

Des procédés d'apports nutritifs avec des blocs enriches en phospore (Phos) ou en sel (Salt) furent utilisés pour suivre la déficience en phosphore chez la race White Fulani au Nigeria. Il est apparu parfois significatif dans certaines zones, mais non significatif dans l'ensemble, que l'alimentation des mères, enrichie en phosphore produisait des veaux plus gros et permettait une croissance plus forte. Le gain moyen en poids pour les mères entre 9 mois et 1 mois avant la naissance, fut de 6,9 kg/mois pour le phosphore (s.d.=5,0; n=50) et 3,8 kg/mois pour le sel (s.d.=4,7; n=54) (p>0,05). Les moyennes carrées pour le poids des veaux de 12 mois fut au moins de 105,2 kg (n=29, s.e.=9,3) pour le phosphore et 91,5 kg (n=37, s.e.=6,3) pour le sel (p>0,05). Pour les animaux de moins de 2 ans la mortalité fut de 6,8% pour le phospore et 13,6% pour le sel (n=179, x2 p<0,01). Il ne fut pas observé de changement dû aux suppléments alimentaires pour le bétail plus agé ou non gravide.

Respuestas A La Suplementacion En Vacuno De Raza Fulani Blanca En Condiciones Agro-Pastorales En Nigeria. Fosforo

Resumen

Se investigó la deficiencia de fósforo en ganado vacuno de raza Fulani Blanca en Nigeria suplementando a los animales en la granja con bloques ricos en fósforo o con bloques de sal. En algunas áreas las vacas suplemantadas con fósforo parieron terneros significativamente más pesados y con un crecimiento más rápido que las vacas suplementadas con sal. Sin embargo, considerando el conjunto de todos los animales estas diferencias no fueron significativas. La ganancia de peso media de las vacas 9–11 meses antes de parto fue de 6·9 kg/mes en los animales suplementados con fósforo (sd=5·0, n=50) y de 3·8 kg/mes en los animales suplementados con sal (sd=4·7, n=54) (P>0·05). Las medias de los mínimos cuadrados de los pesos de los terneros a los 12 meses de edad fueron de 105·2 kg (n=29, se 9·3) en el grupo suplementado con fósforo y de 91·5 kg (n=37, se 6·3) en el grupo suplementado con sal. En animales de menos de 2 años de edad, la mortalidad fue del 6·8% en el grupo suplementado con fósforo y del 13·6 en el grupo suplementado con sal (n=179, P<0·01 según test Chi cuadrado). En animales más viejos y en vacas no preñadas no se observó ninguna respuesta a la suplementación.
