ObjectiveThe present study attempted to determine safe and sufficient growth promoters in poultry feeding.MethodsA total of 520 seven-day-old quail chicks were randomly allotted to eight treatment groups in a 4×2 factorial design experiment to evaluate the effect of different levels of humic acid (HA) and black cumin (BC) seed and their interactions on growth, carcass traits, gut microbes, and blood chemistry of growing quails. Quails were randomly distributed into 8 groups in a 4×2 factorial design, included 4 HA levels (0, 0.75, 1.5, and 2.25 g/kg diet) and 2 BC levels (0 or 5 g/ kg diet).ResultsIncreasing HA level associated with a gradual increase in final weight, feed intake and body weight gain along with an improvement in feed conversion ratio. Dietary addition of 5 g BC powder/kg diet gave similar results. The highest level of HA (2.25 g/kg diet) recorded the best values of carcass weight, breast yield, intestinal length, and intestinal weight comparing with the control and other HA levels. Total viable microbial counts decreased (p<0.05) with increasing levels of HA except the intermediate level (1.5 g/kg diet). The concentration of serum cholesterol and low density lipoprotein (excluding that 0.75 g HA) decreased (p<0.05) and high density lipoprotein increased (p = 0.034) along with increasing HA level. The interaction between the 2.25 g HA×5 g gave the best results regarding most studied parameters.ConclusionThese findings indicated that HA combined with BC could be used as effective growth promoters, with the recommended level being 2.25 g HA+5 g BC/kg of quail diet.
The main aim of this paper is to review and evaluate the performance of Pakistani basmati to international markets and to estimate the impact of different factors on basmati export from Pakistan. For this purpose, panel data of eleven markets are collected from 2003 to 2016. Independent macroeconomics variables used in the study are exchange rate of Pakistan, exchange rates of trading partner, inflation in Pakistan, inflation in trading partner and dummy variables joint border and religion by application of Park's Feasible Generalized Least Square (FGLS). Result of this study showed that exchange rate of Pakistan has negative and significant effect on basmati export but exchange rate of trading partner has positive and significant effect on basmati export of Pakistan to its trading partner. The inflation in Pakistan has negative and significant effect on basmati exports from Pakistan to its trading partner. If Pakistan wants to improve its export value of basmati rice, there must be an effective strategy to control the inflation in Pakistan or at least need to make policy for minimizing the impact of inflation for the rice producers. If it is very difficult to control the inflation there must be subsidies for rice growers for inputs used in the basmati production. The high rates of inflation in trading partners have positive and significant impact on the demand of Pakistani basmati is an indication for Pakistani exporters to mark extra motivation on those international markets where inflation is comparatively high. Dummy variables for Muslims and joint boarders have positive and significant impact on basmati export flow from Pakistan to its trading partner. The results of dummy variables showed that there must be more emphasis on the neighbor and Muslim countries for improving the export value of Pakistani basmati.
The present study was planned to test the hypothesis that feeding lactating dairy cattle with varying levels of rumen-undegradable protein (RUP) can enhance protein utilization, milk production, milk protein, and nitrogen (N) excretion. Forty midlactating crossbred (Jersey × Friesian) cattle were randomly divided into four groups.Four treatment diets were formulated to contain 30%, 40%, 50%, and 60% RUP of crude protein. Dry matter (DM) and crude protein intakes were signifi cantly reduced with increasing dietary RUP levels. Crude protein digestibility increased linearly with incremental increases in dietary RUP levels. Cattle fed 60% RUP showed a linear decrease in N intake compared to that in the other groups. A linear decrease in urinary N and linear increases in net N, milk N, and N-use effi ciency were observed with increasing dietary RUP levels. Actual milk, energy-corrected milk, and 4% fat-corrected milk yields (kg/day) increased linearly with an increasing degradability of protein. However, milk protein, solids not fat and total solids, as well as the yields of protein, fat, and lactose, showed signifi cant increases with increased RUP supplementation. Collectively, the results indicate that formulating dairy cow diets to contain 60% RUP results in better lactating performance and N-use effi ciency and lower N excretion.
This has encouraged improved effort at finding cheaper alternatives to prolong the production of poultry and maximize the potentials of the improved poultry strains available, at a reasonable cost. Pp is an important grain legume commonly grown and consumed in both tropical and subtropical regions of the world. It is also known as "lobiaadassy" (6). According to Saxena (7) the area cultivated has jumped to over 4.92 × 10 6 ha. It is considered a multipurpose nitrogen-fixing plant that provides food, fuel wood, and fodder as well as shelter material to farmers throughout the world. The shells, leaves, seeds, and young stems of Pp could be a good protein source for poultry feed. This plant can tolerate drought conditions and has greater adaptability to poor soil conditions as compared to most other tropical legumes (8). It is widely cultivated throughout the tropics as a cover crop or green manure crop and it has high dry matter yield potential. Cajanus cajan contains crude protein (CP) of Abstract: A trial was conducted to evaluate the effect of different processing methods of pigeon pea (Pp; Cajanus cajan) on fattening performance and carcass traits as well as blood biochemical and hematological parameters of broiler chickens. For this purpose, 300 dayold chicks were assigned to 5 treatments. Each treatment had 5 replicates and contained 12 birds each under a completely randomized design. Five isonitrogenous and isocaloric diets were formulated with the inclusion of pigeon pea crushed (control, PPC), boiled with potash (PPP), boiled (PPB), soaked (PPS), or roasted (PPR) at the rate of 20% of the basal diet. The highest values of weight gain were observed in chicks fed the PPP diet through the starter and overall periods. Throughout the starter phase, the feed conversion ratio was significantly affected by dietary treatments. Highest values for carcass and breast weight were observed in birds fed the PPP diet as compared to the control diet. Blood biochemical parameters were not statistically influenced by Pp treatments. Hematology was also similar in all the diets. In conclusion, PPP can be used as a protein source in broiler diets and it can improve the growth performance of broilers.
