1. Chicks and turkey poults were fed for 3 weeks on low-zinc diets, prepared from purified ingredients, supplemented with zinc oxide at graded levels.2. Birds of both species given the unsupplemented basal diets grew poorly, with high mortality rates. All had severe hyperkeratosis but bone development was normal. Only when birds received diets with low concentrations of added Zn were leg abnormalities observed.3. Zn requirements were assessed visually from dose-response graphs. The chick required 18 mg Zn/kg diet for maximal live weight and 24 mg Zn/kg for maximal Zn concentration in blood serum. The responses of tibial Zn and net retention of Zn did not reach plateaux within the range of dietary Zn concentrations studied. The turkey poult's Zn requirement for maximal live weight was 25 and 28–29 mg/kg for net retention of Zn and for maximal concentration of Zn in blood plasma and in the tibia; 41 mg Zn/kg diet was required for maximal Zn in blood serum.4. Liver Zn was not correlated with dietary Zn in either species.

Effects of supplemental dietary lysine and methionine in a Groundnut Cake (GNC) based diets on meat and bone characteristics of broiler chickens were investigated. In a completely randomized design, a total of 168 one - day – old Arbor acre broiler chicks were randomly allocated to seven dietary treatments each in triplicate of eight birds per replicate. The Seven starter and finishers’ diets were: GNC based diets without any amino acid (lysine or methionine) supplementation (T1); GNC diet + 0.2% lysine (T2); GNC diet + 0.4% lysine (T3); GNC diet + 0.2% methionine (T4); GNC diet + 0.4% methionine (T5); GNC diet + 0.2 lysine and 0.2% methionine (T6) and GNC diet + 0.4% lysine and 0.4% methionine (T7). Experimental diets and water were offered to birds ad libitum in an experiment lasting six-week. At day 42, two birds per replicate were slaughtered, meat and bone characteristics determined. There were significant variations (P<0.05) in the crude protein (%) and ether extract (%), pH1 and pH2 of meat. Thiobarbituric acid reactive substances composition of meat at days 0, 5, and 10 were similar (P<0.05) and were not affected by dietary amino acid supplementation. Tibiotarsal index (mg/mm) of bone (22.10, 27.25, 33.35, 31.40, 28.70, 31.45 and 29.75 for broilers on T1, T2, T3, T4, T5, T6 and T7, respectively) were increased significantly (P<0.05) by amino acid supplementation. Significantly differences (P<0.05) were observed in the calcium, phosphorus and potassium (%) contents of broilers’ bone across treatments. Supplemental lysine and both lysine and methionine improved meat quality and bone development of broiler chickens in this study.

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

Dietary Treatments

The influence of insect protein origins on broiler chicken meat parameters were studied using 135 day old Arbor acre birds subjected to three dietary treatments: Diet A comprised of a standard feed of the brand name ‘vital feed’ containing fishmeal as the major protein source (control), while Diet B and Diet C contained insect meal from African palm weevil larvae (Rhynchophorus phoenicis), respectively, winged termite (Macrotermes bellicosus) as replacement for fishmeal. Forty five broiler chicks were randomly assigned to each of the dietary treatments at the rate of fifteen chicks per replicate making three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were housed in similar cages and subjected to similar husbandry and sanitation practices, such that the only source of variation was the dietary treatments. After eight weeks of the experiment, carcass quality and organ weight measurements were analysed using appropriate statistical analysis. The result obtained showed that the broiler chickens fed insect meals performed significantly (P<0.05) better in terms of live weight gain (2,200.85±64.23 g and 2,046±58.40 g for Diet B and Diet C) compared to control. Carcass quality relating to defeathered weight and eviscerated weight also followed a similar trend with Diet B (2,187.74±62.72 g and 1,788.93±70.70 g), Diet C (2,015.83±74.62 g and 1,466.97±100.05 g), and Diet A (control; 1,526.47±47.40 g and 1,240.30±64.53 g). The records of cut-up parts and organ weight measurements were also significantly different (P<0.05) for the birds on insect meal (Diet B and Diet C) than those on fishmeal based diet (Diet A). The result showed that insect meal can effectively serve as a major source of protein in poultry feed formulation.

The results of studying the effects of water-alcohol infusions of medicinal plants - rhizomes of thick-leafed incense (Bergenia crasslifolia L. Fritsch), dioica nettle leaves (Urtica dioca L.), burdock roots (Arctium lappa L.), and mother-and-leaf leaves - are presented. ordinary machichi (Tussilago farfara L.) on the organism of laboratory rats under conditions of short-term intoxication with heavy metals in doses of 25 mg of lead and 2.5 mg of cadmium per 1 kg of live weight. In the course of studies it was found that the effect of heavy metals on the body of laboratory animals is selective - the main “depot” of lead was bone tissue, and cadmium - the kidneys and liver. The addition of 1 ml of water-alcohol infusions from medicinal raw materials to the diet of rats as detoxicants caused a decrease in the level of lead in the animal organism to 6.32 times, cadmium to 3.46 times. The greatest detoxification ability was shown by infusions of the roots of burdock and leaves of nettle dioecious. Under the influence of elevated doses of lead and cadmium in laboratory animals there was an increase in heart mass by 40.34 % and spleen by 89.91 %, a decrease in the content of alkaline phosphatase in blood serum by 25.81 %. Water-alcohol infusions normalized the biochemical parameters of rat blood serum. Studies have shown that the infusions of rhizomes of thick-leafed frangipani, burdock roots, dioecious nettles and coltsfoot leaves with antioxidant properties can be the basis for the development of an effective herbal preparation used for the prevention and treatment of animals from intoxication with salts of heavy metals.

Abstract This study was conducted to explore the effect of the zinc oxide nanoparticles (ZnONPs) supplement on the regulatory appetite and heat stress (HS) genes in broiler chickens raised under high or normal ambient temperatures. In this study, 240 one-day-old male broiler chicks (Cobb 500) were randomly assigned to 48 battery cages. From day 1, these 48 cages were randomly subjected to four different treatment strategies: Control (wherein, their basal diet included 60 mg/kg of ZnO), ZNONPs 40 (wherein basal diet included 40 mg/kg of ZnONPs), ZnONPs 60 (basal diet included 60 mg/kg of ZnONPs), and ZnONPs 100 (basal diet included 100 mg/kg of ZnONPs). Thereafter, from day 22 to 42, the chickens from each dietary treatment group were subjected to different temperature stresses either normal (23 ± 1 °C constant) or HS (34 ± 1 °C for 6 h/d), which divided them into eight different treatment groups. Our findings revealed that dietary ZnONPs altered the gene expression of cholecystokinin (ileum), heat stress proteins (HSP) 70 (jejunum and ileum), and HSP 90 (duodenum, jejunum, and ileum). The gene expression of ghrelin was affected by the interaction between the ZnONPs concentration and temperature in the duodenum and stomach. More studies are required to elucidate its complex physiological and biochemical functions of the regulation of gene expression within the intestine in heat-stressed broiler chickens.
