Preliminary investigation on the effect of dietary supplemental biotin and palm kernel oil on blood, liver and kidney lipids in chicks.

A total of 480 day-old broiler chicks were used in two trials conducted to investigate the performance and lipid contents of blood, liver and kidneys of birds when fed varying levels of palm kernel oil (0% and 2%) and biotin (40, 80, 120, 160, 200 and 240 mcg/kg feed) in a 2 x 6 factorial experimental design. The results showed that blood, liver and kidney lipid concentrations were significantly affected by dietary biotin treatments. While total lipid, free fatty acid, triglyceride and cholesterol contents were negatively correlated with dietary biotin level, phospholipid concentrations were positively correlated. Biotin-deficient chicks had significantly higher total lipid, free fatty acid, triglyceride and cholesterol but lower phospholipid contents in their blood and the two organs. Supplementation of the diet with 2% palm kernel oil significantly elevated blood phospholipid concentration, but depressed the accumulation of the other lipid fractions in both organs and the blood of birds. Blood, liver and kidney cholesterol concentrations were not affected by 2% fat supplementation. Observation on the lipid parameters coupled with the results on feed utilisation appeared to suggest that a minimum of 120 mcg of the vitamin per kilogram of diet was required by broiler chicks for optimum performance.

The biotin requirement of broilers feed maize-palm kernel meal based ration.

6 duplicate floor pens with 20-day-old commercial broiler chicks each, were fed practical-type broiler diet with maize-palm kernel meal, supplemented with graded levels of biotin so that the rations had 40, 80, 120, 160, 200, and 240 micrograms of the vitamin per kg of feed. This treatment was maintained for 6 weeks. Estimation of the body weight, feed intake, blood glucose concentration, and lipid contents of liver, kidney and blood showed that dietary biotin of 120 micrograms/kg feed is a minimum requirement. 160 micrograms/kg feed was required for the prevention of dermatitis, mortality due to fatty liver and kidney syndrome (FLKS) and leg deformities.

Effect of dietary palm kernel oil and biotin on the fatty liver and kidney syndrome in broiler chicken.

The effect of feeding biotin and palm kernel oil to broiler chicks on the appearance of Fatty Liver and Kidney Syndrome (FLKS) was investigated. A total of 480 broiler chicks was divided into two equal batches each of which was divided into 6 groups of 40 chicks per group. Each group was further subdivided into equal units of 20 chicks. Six dietary levels of biotin (40, 80, 120, 160, 200, and 240 mcg/kg feed) were given to the first batch of chicks, while the second batch had 2% palm kernel oil added to the six dietarybiotin levels. These two basic rations were supplemented with biotin in order to obtain six levels of the vitamin in the rations. The results showed that the 2% palm kernel oil forage affected FLKS mortality and the minimum biotin requirement. FLKS mortality was significantly reduced in case of palm kernel oil supplement. A lower amount of biotin (120 mcg/kg feed) was needed in case of palm kernel oil supplement-as compared with the necessary biotin (160 mcg/kg feed)-in order to prevent FLKS mortality when palm kernel oil was not contained in the rations. The biochemical analysis of the liver and kidney syndrome-coupled with the correlation and regression analysis of the data collected-showed that a minimum of 120 mcg/kg feed was needed by broiler chicks for the prevention of FLKS.

[Climatic factors modifying the performance of cattle in Nigeria].

Continuing previous analogous investigations on climatic factors limiting the performance of cattle, temperature and humidity values were determined in southern Nigeria and were related to the established physiological compatibility conditions for cattle. A good agreement was found between the values determined in 1984 and 1985. On average (for both years) the outside temperatures surpassed the physiologically-compatible limit of 24 degrees C to the extent of 57.8%. Not more than 1.3% of the total hours were within the optimum temperature range for cattle. The values for the relative humidity were within the optimum cattle range by 27.4% in the two-year average, whereas they were too moist by 35.1%.

Comparative investigations of the feed and nutrient consumption, growth, a nutrient efficiency of broiler chickens under different climatic conditions in Nigeria.

Feed intake, growth and blood parameters were studied over 3 years, in 2,300 chickens started either during the cool, dry season or the hot, dry season. From day old to 4 weeks, fed was more efficiently used for growth during the hot, dry season than for the cool, dry season. Using Haemoglobin and Haematocrit as criteria, and on supplementing a practical type ration with copper and iron, it was observed that climatic stress, as distinct from mineral deficiency, plays an important role in the brooding of exotic chickens in the tropics. The importance of this in relation to housing and timing of brooding the chickens by commercial producers was highlighted.

Vitamin A requirement of broiler chicks in Nigeria.

Feeding of a vitamin A deficient diet resulted in cessation of growth of RIR chicks at between 19 and 24 days of age. When depleted chicks were fed graded levels of vitamin A acetate it was observed that the minimum requirement was 90 IU/100 g of diet. Trials with four commercial strains of broiler chicks revealed strain differences with respect to the requirement when body weight gain, feed conversion, liver storage of the vitamin, and blood uric acid were used as indicators of vitamin A status. Coccidiosis was induced and the results showed that under practical conditions at least 150 IU of vitamin A per 100 g of diet should be fed in Nigeria.

Riboflavin requirement of starting chickens in a tropical environment.

Growth rate of broiler chicks tends to be lower in the tropics than in the temperate zone. Results show that up to 17% of dietary riboflavin is destroyed within 24 hours of exposure of the feed to light hence the level of 3.6 mg. of vitamin B2 recommended does not meet the requirement for growth of broilers. Growth study as well as accumulation of riboflavin in meat and organs of the birds showed that increasing levels of dietary riboflavin increases its deposition in meat and organs of the birds. Optimum growth of birds and storage of riboflavin in the body is attained in the tropical environment when 5.1 mg. of the vitamin is added per kg. of practical ration.
