Abstract

The experiment was conducted to investigate the effect of four stocking densities on the production performance i.e. Weight Gain, Feed Consumption, Feed Conversion ratio (FCR) and Mortality of Hubbard broilers chicks. Four of the stocking density treatments; 10birds/m², 12birds/m², 9birds/m² and 8birds/m² were provided to the four groups A, B, C and D, respectively. The experiment was conducted for 2 to 6 week of age of the birds (7 days adaptation period and 35 days experimental period). Water and feed were provided ad libitum. Twenty three hours light was provided. When the data calculated for weight gain, feed intake, and feed conversion ratio was analyzed statistically; the difference between the stocking density treatments was found to be non-significant. Mortality for the four groups A, B, C and D was recorded as 6.67, 10.00, 3.33 and 0.00 percent, respectively. However, the birds those were highly stocked showed the highest mortality in the study.

Abstract

Chemical analysis, apparent metabolizable energy and one feeding trial were conducted to assess the nutritional value of jackfruit seeds that had been subjected to a combination of soaking, boiling, followed by fermentation. In the feeding trial, five broiler starter diets were formulated with the processed jackfruit seed meal constituting 0, 80, 160, 240 and 320 g/kg of the diet. The jackfruit seeds before and after processing contained 151, 140 g crude protein; 740, 747 g total carbohydrates; 11.1, 1.28 g tannins; 10.0, 1.47 g total oxalates per kg respectively. The apparent metabolizable energy value of the processed jackfruit seed meal was 2368±315 Kcal/kg. Inclusion of the processed jackfruit seed meal affected chick growth, nutrient utilization and organ weights relative to body weight. At 80 and 320 g/kg inclusion, weight gain and feed/gain were depressed by 5.2, 42.1%; 6.2, 40.7% respectively. Feed intake was not affected up to 240 g/kg inclusion but reduced by 18.3% at 320 g/kg. Except for gizzard; weights of liver, caecum, heart, intestines and pancreas were affected. At 80 and 320 g/kg inclusion; weights of caecum, intestine, pancreas and gizzard increased by 69.4, 113.9%; 4.5, 43.2%; 7.3, 46.3%; 11.3, 14.6%, while liver and heart were reduced by 7.7, 22.2%; 27.9, 34.2% respectively. Apart from nitrogen retention; nitrogen digestibility, dry matter digestibility and excreta water content were not affected. Nitrogen retention increased by 38.5% at 320 g/kg inclusion. Processing reduced tannins and oxalates from jackfruit seeds by over 85%. The processed jackfruit seed meal can be included in poultry diets at levels up to 80 g/kg without compromising with: feed intake, feed efficiency, daily weight gain and nutrient utilization. Although the cost per kg gain of birds increased with jackfruit seed meal inclusion, the seeds will eventually be readily available at low or no cost. However, for economic efficiency the cost of collection and treatment should be put into consideration.

Requirement of Calcium and available Phosphorus for Laying Japanese quail birds (Coturnix coturnix japonica) in Nigeria 

31-38

A.Y. AGUDA, A. A. Sekoni and J. J. OMAGE

Abstract

An experiment was conducted to evaluate the performance and egg production of Japanese quail (Coturnix coturnix japonica) fed diets with varying calcium (Ca) and available phosphorus (aP) levels. A total of 270 female quails (7weeks old) were raised on deep litter for fourteen weeks (98 days). The birds were assigned to nine dietary treatment groups of 30 birds each with three replicates of 10 birds per pen. They were fed nine dietary treatments with three levels of Ca (2.5, 3.0, and 3.5%) and three aP levels (0.35, 0.45 and 0.55%). The diets were formulated to be iso-nitrogenous (22%CP) and iso-caloric (2630kcal/kgME). Results revealed highest final weight, hen housed production for diets containing 2.5% Ca+0.35%aP. Feed conversion ratio and feed cost per crate of egg were also lowest for 2.5%Ca+0.35%aP. Diet containing 2.5%Ca+0.45%aP yielded the lowest average daily feed intake. Birds fed 3.5%Ca+0.35% aP yielded the highest average egg weight but highest mortality. The result of single effect of calcium revealed lowest mortality for 2.5%Ca. For single effect of Phosphorus, 0.35% resulted in the highest final weight but had the lowest average daily feed intake. The result of the layer phase showed that quails from (7-20) weeks can be raised optimally on 2.5%Ca+0.35%aP.

Influence of Varying Levels of Corn Steep Liquor on Nutrients Intake, Digestibility and Growth Response in Growing Buffalo Calves

Abstract

This study was planned to examine the influence of varying levels of corn steep liquor on feed intake and growth performance of growying nili-ravi male buffalo calves. Fifty male buffalo calves of 9 month old were randomly divided into five groups, 10 animals in each group, using Randomized Complete Block Design. Five isonitogenous (16% crude protein) and isocaloric (2.6 Mcal/kg) diets were formulated. The control diet had 0% corn steep liquor and in 20, 40, 60 and 80% diets, urea on nitrogen equivalent was replaced by corn steep liquor, respectively.Animals were given weighed amount of feed twice daily at ad libitum. The daily feed offered and refusals were recorded to calculate dry matter intake. The sample of feed offered and refusal were used to determine dry matter, crude protein, neutral detergent fiber and acid detergent fiber. Animals fed 40% corn steep liquor diets ate highest dry matter (3.33kg daily)and was the lowest (3.16 daily) by those fed 40% corn steep liquor diets. The neutral detergent fiber and acid detergent fiber digestibility was higherin animals fed diets containing corn steep liquor than those fed diet containing 0% level. However, dry matter and crude protein digestibility remained unaltered across all diets. Calves fed 40% corn steep liquor diets gained more weight (757 g/day) than those fed 80% (637 g/day). Pre slaughter weight of animals fed 40% corn steep liquor diet was the highest (141.5 kg) and was the lowest (130 kg) in those fed 80% corn steep liquor diet. Warm carcass weight was higher in animals fed 40% (65.8 kg) diet followed by those fed 60%, 80%, 20% and control diets. Primal cuts, ash, Na, K and Ca remained unchanged across all diets. The red blood cell count, white blood cells, packed cell volume and hemoglobin values were also same across all diets. In conclusion, animals fed CSL40 diet gained more weight and were cost-effective when compared to those fed control, 20%, 60% and 80% diets.
