Livestock form a major means of livelihood in Burkina Faso where almost 80% the rural population keep sheep and goats. However, constraint to livestock productivity is seasonal feed scarcity. To bridge increasing gap, particularly dry season, keepers are increasingly turning purchase feeds from markets, which has led emergence markets peri-urban towns cities Sahel. characterize dynamics these i...

The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...

Cows will typically experience a 30 to 35% reduction in feed intake during the final two to three weeks prior to calving. Blood fatty acids at calving are negatively related to feed intake and positively related to incidence of postpartum metabolic disorders. Feed and manage cows to maximize feed intake during the transition period. Over conditioned cows are likely to have poor appetites, but d...

While not a new ingredient in livestock feed, the volume available and the relative price of DDGS have forced many feed manufacturers into using greater levels than ever before. The use of DDGS has caused feed manufacturing problems at nearly every phase of feed manufacturing. These include railcars that simply won’t unload, feeder screws and supply bins that are wrong for the ingredient, nutri...

Turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. In order to obtain desired surface quality by machining, pr...

This experiment was conducted, during a seven-week period to investigate, the effects of using various levels of garlic cloves and turmeric rhizome powders, on laying hens’ performance, egg quality characteristics and cholesterol content in yolk. Two hundred and sixteen, 27-weeks old Novogen white laying hens were assigned randomly into nine treatments with eight replicates of three birds each....

Data were collected over the first 4 generations of a divergent selection experiment for residual feed intake of Large White pigs having ad libitum access to feed. This data set was used to obtain estimates of heritability for residual feed intake and genetic correlations (r(a)) between this trait and growth, carcass, and meat quality traits. Individual feed intake of group-housed animals was m...

Molting is a process by which a hen's reproductive tract is rejuvenated prior to the beginning of a laying cycle. This process is often artificially induced in commercial settings in order to extend the productive life of a flock of hens. The most common method for the induction of molt is feed withdrawal for a period of several days. It has been noted that feed withdrawal, while effective in i...

this study was conducted to evaluate the effects of different levels of butyric acid triglyceride and prebiotics on performance, egg quality traits and blood lipids of laying hens.  a 2 × 4 factorial experiment with 4 levels of butyric acid triglyceride (0%, 0.15%, 0.30%, 0.45%) and 2 levels of prebiotic (0 and 0.15%) based a completely randomized design were conducted. one hundred and ninety-t...

This experiment was conducted to measure the effects of olive leaf powder on performance, egg yield, egg quality and yolk cholesterol level of laying hens. A total of 120 Lohmann Brown laying hens of 22 weeks old were used in this experiment. The birds were fed on standard layer diets containing 0, 1%, 2%, or 3% olive leaf powder for 8 weeks. Egg weight and yield were recorded daily; feed intak...
