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.

The purpose of this study was to evaluate the effect of fat sources and emulsifier supplementation in different phases on growth performance of broilers. Treatments were; (T1) basal ration (BR) which contained soy oil (SO) and had inclusion of emulsifier for whole life, (T2) BR which contained poultry fat (PO) and had inclusion of emulsifier for whole life, (T3) BR which contained oxidized oil (OO) and had inclusion of emulsifier for whole life, (T4) BR which contained SO and had inclusion of emulsifier during starter phase (T5) BR which contained PO and had inclusion of emulsifier during the starter phase, (T6) BR which contained OO and had inclusion of emulsifier during the starter phase, (T7) BR which contained SO and had inclusion of emulsifier during the starter phase (T8) BR which contained PO and had inclusion of emulsifier during the grower phase, (T9) BR which contained OO and had inclusion of emulsifier during the grower phase, (T10) BR which contained SO and had inclusion of emulsifier during the finisher phase, (T11) BR which contained PO and had inclusion of emulsifier during the finisher phase (T12) BR which contained OO and had inclusion of emulsifier during the finisher phase. The Basal ration which contained SO and supplemented emulsifier during the grower phase and throughout life increased the body weight gain. The supplementation of emulsifier in the finisher phase and throughout life in a diet which contained SO had better feed conversion ratio. The supplementation of emulsifier in the finisher phase and throughout life in SO based diet increased the dry matter and crude fat digestibility. We recommend emulsifier supplementation in the finisher phase for the economic point of view.

Land modification and its allied resources have progressively become a severe problem presently pulling the worldwide attention and now it rests at the central point of the conservation of the environment and sustainability. The present research aimed to examine the land-use changes and their impact on agricultural production using remote sensing and GIS techniques over the study area that comprised of Tehsil Shorkot, District Jhang, Punjab, Pakistan. Images were pre-processed by using the Arc GIS and ERDAS Imagine 15 software for stacking of the layers, sub-setting, and mosaicking of the satellite bands. After the pre-processing of the images, supervised image classification scheme was applied by employing a maximum likelihood algorithm to recognize the land-use changes which have been observed in the area under study. The area under water was occupied 9.6 km2 in 2010 that increased to 21.04 km2 in 2015 and decreased to 19.4 km2in 2020. Built-up land was 16.6 km2 in 2010 that increased to 19.4 km2 in 2015 and 26.8 km2 in 2020. The total area under vegetation was computed as 513.2 km2 in 2010 that increased to 601.6km2 in 2015 and further increased to 717.7 km2in 2020. Forest land use showed decreasing trend as the covered area in 2010 was occupied 90.8 km2 that decreased to 86.7 km2 in 2015 and further decreased to 61.84 km2 in 2020. In 2010, barren land use was occupied 528.54 km2 that considerably decreased to 429.64 km2 in 2015 further decreased to 333.1 km2 in 2020. Barren land drastically decreased into watered, built-up, and vegetation land uses. The findings of this study will be helpful for the future conservation of various land-use types, urban and regional planning, and an increase in agricultural production of various crops in the study area.

This experiment was planned to evaluate the effects of phytase supplementation with or without organic acid (OA) on performance, protein, calcium (Ca), phosphorus (P) and sodium (Na) digestibility and carcass parameters in broiler chickens fed low Ca and low P diets in comparison to a high Ca and high P diet with standard specifications. For this purpose, two iso-nitrogenous and iso-caloric diets were prepared in such a way that one diet had high Ca (9.80) and high P (4.50) and second diet had low Ca (8.50) and low P (2.40), respectively. Low Ca and low P diet was further supplemented with enzyme phytase @ 500 FTU/ kg, and phytase @ 500 FTU/kg + organic acid (1 kg/ton). Rations were offered to seven replicates of ten birds each, from day 1 to 21. Results revealed that the experimental treatments had no effect on feed intake and growth performance of birds (p>0.05). Carcass parameter results showed highest thigh meat yield % and liver weight % in the birds fed diet with low Ca & P and supplemented with enzymes phytase (p<0.05). Fecal P and Na digestiblities were high (p<0.05) in experimental broilers fed low Ca low P with enzyme phytase supplementation as compared to the diet without phytase supplementation. It is concluded that phytase and OA supplementation in the starter diet with low Ca and low P level did not influence intake, growth and feed conversion of the broilers. However, thigh meat yield percent and mineral digestiblities (P and Na) increased in the broilers that received the diet with low Ca and low P level and supplemented with enzyme phytase.
