Jack Bean

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.

Abstract A 90-day study was carried out with 36 West African Dwarf goats to determine the effect of Moringa oleifera leaf meal (MOLM) on feed intake, body weight changes and haematology of WAD does. Four diets were formulated such that diets T1, T2, T3 and T4 contained MOLM at 0%, 5%, 10% and 15%, respectively. The diets were offered to the goats, which were randomly divided into four groups of nine goats each in a completely randomized design. Average daily feed intake (ADFI), average daily weight gain (ADWG), feed conversion ratio (FCR) and heamatology of the animals were determined and statistically analyzed. Results showed that ADFI, ADWG differed significantly (P<0.05) with T4 goats having better values. FCR was however best for does fed T4 diet. PCV, RBC, MCV and WBC differed (P<0.05) significantly among the treatments. Packed cell volume (29.50-32.75%) was improved (p<0.05) by MOLM supplementation at 15% inclusion level. White blood cell counts for goats in treatment groups were significantly (p<0.05) higher and better than the control. Incorporation of 15% MOLM in diets of WAD does enhanced their performance and heamatological profile. Moringa oleifera leaf meal supplementation level at 15% was recommended for optimum West African Dwarf goat production.

The effect of rebreeding interval on the reproductive performance and body weight changes of does during pregnancy was investigated using 24 multiparous crossbred (New Zealand White X California) does. The does were placed on three treatments comprising mating at 14, 21 and 28 days postpartum. The docs were served 250g-concentrate meal (23% CP und 2600 kcal ME/kg) daily, while water was given ad libitum. Parameters monitored were doe willingness to mate, doe weights during pregnancy, feed intake, pregnancy rate, litter size and weight at birth, alive at birth and up to 21 days postpartum and stillbirth rate. Kits were weaned at 4 weeks of age. Results obtained showed that does mated 14 days postpartum lost more weight in the second week of pregnancy than the other groups. Rebreeding interval did not significantly (P>0.05) affect doe weight gain in the 19, 3" and 4th weeks of pregnancy. Does mated 14-d postpartum had significantly (P<0.05) higher feed intake during the l", 2nd and 3rd weeks of pregnancy. Feed:guin ratio was higher for does mated 21 d postpartum than for other treatments. Pregnancy rate was higher in the 14-d group and lowest in the 28-d group. Willingness to mate also decreased with increasing rebreeding interval. Litter size at birth, number of kits alive at birth and up to 28 days postpartum were not affected (P>0.05) by rebreeding interval as was the case for litter birth weight and percent stillbirths. Does mated 14 days postpartum however, had numerically more kits alive at birth and up to 28 days postpartum than the other groups. Litter weights were slightly higher for does mated 14 and 21 days postpartum than 28 days. It is concluded from this study that mating does 14 days postpartum under tropical conditions could increase the number of kits weaned per doe and hence increase profitability of the rabbit production enterprise.

Body weights and measurements of 694 first, 519 second and 329 third lactation cows in five Research Branch herds of the National Cooperative Dairy Cattle Breeding Project of Agriculture Canada were studied. The A line cows were daughters of U.S., Canadian and Finnish Ayrshire proven bulls, Brown Swiss and Norwegian Red proven bulls and young Research Branch Ayshire bulls and Research Branch Ayrshire cows. Highly selected U.S. and Canadian Holstein proven bulls and young Research Branch bulls mated to Research Branch Holstein cows produced the H-line cows. The model for analysis contained fixed effects for station, year of birth, line, sire group within line and sire within sire group within line as classification variables and age at calving as a covariable. Sire group, line, station and sire had significant effects on all weights studied. However, most effects were not significant for weight changes. Daughters of Brown Swiss and Norwegian Red sires were nearly as heavy as the daughters of Holstein bulls. On average, cows lost about 20 kg of weight from calving to 56 days postpartum of first lactation. The older first calvers were found to lose more weight from calving to 56 days of first lactation and gain less weight from 56 days postpartum onward than the younger first calvers. The effects of station, line and age at calving were significant for most body measurements. Sire group effects were significant for 13 out of 24 measurements. Significant differences between sire groups existed in stature (withers height) at all lactations and ages. In contrast, body length (shoulder to hook) did not differ significantly between sire groups from 112 days of first lactation onward. Key words: Body weight changes, body measurements, dairy cattle

AbstractA 2-year study compared milk production and profitability for confinement feeding versus rotational grazing. Guernsey and Guernsey x Holstein cows grazed perennial grass pastures from mid-May to October or were fed in confinement. Averaged over both years, confined cows produced 7% more milk; their milk was similar in fat concentration to that of grazing cows. Body weight changes and health of the two groups were similar. Net return per cow averaged $64 higher for rotational grazing than for confinement because of lower costs for feeding, facilities, equipment, and labor. Intensive rotational grazing of pastures is a competitive alternative for dairy cow feeding. However, farmers in the northern U.S. will still require stored feeds from late fall through early spring.
