A quarter of all anthropogenic methane emissions in the United States are from enteric fermentation, primarily from ruminant livestock. This study was undertaken to test the effect of a methane inhibitor, 3-nitrooxypropanol (3NOP), on enteric methane emission in lactating Holstein cows. An experiment was conducted using 48 cows in a randomized block design with a 2-wk covariate period and a 12-wk data collection period. Feed intake, milk production, and fiber digestibility were not affected by the inhibitor. Milk protein and lactose yields were increased by 3NOP. Rumen methane emission was linearly decreased by 3NOP, averaging about 30% lower than the control. Methane emission per unit of feed dry matter intake or per unit of energy-corrected milk were also about 30% less for the 3NOP-treated cows. On average, the body weight gain of 3NOP-treated cows was 80% greater than control cows during the 12-wk experiment. The experiment demonstrated that the methane inhibitor 3NOP, applied at 40 to 80 mg/kg feed dry matter, decreased methane emissions from high-producing dairy cows by 30% and increased body weight gain without negatively affecting feed intake or milk production and composition. The inhibitory effect persisted over 12 wk of treatment, thus offering an effective methane mitigation practice for the livestock industries.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.

Three groundnut meals namely: groundnut cake (GNC), locally processed groundnut cake (kulikuli) and toasted groundnut seed(kernel) meal (TGSM) were incorporated in rabbit diets at two levels to generate six diets: 18% GNC, 22% GNC, 18% Kulikuli, 22% Kulikuli, 18% TGSM and 22% TGSM respectively, and 18% GNC also served as the control diet. Twenty four (24) six weeks-old growing rabbits of mixed breeds and sexes with mean initial weight of 568.75±l2.85g were randomly allocated to the six dietary treatment groups, such that each had four rabbits and each rabbit formed a replicate in a completely randomized design laid out in a 2X3 factorial arrangement and fed ad libitum, for 70 days. The main effects showed that while the treatment groups fed TGSM were significantly depressed (p<0.05). rabbits fed GNC and kulikuli were not significantly different (p>0.05) for average daily feed intake, daily body weight gain and final body weight. Feed conversion ratio (FCR) was not significantly (p >0.05) affected among treatment groups. Rabbits fed TGSM had significantly (p<0.05) better apparent digestibility coefficient (78.04%) than those on kulikuli (75.81%6) and the group on kulikuli were better than animals fed GNC (72.09%) for fat digestibility. Fibre digestibility was also significantly different (p <0.05), with rabbits fed kulikuli having the poorest fibre digestion (15.63 %). Crude protein, dry matter and NFE apparent digestibility coefficients were not significantly (p >0.05) affected. Among all the parameters measured, only fat and fibre digestibility coefficients had significant (p <0.05) interactions and NFE digestibility was significantly affected (p <0.05) by level of inclusion, with groups fed 22% digesting it better. Feed cost kg gain did not differ significantly (p >0.05) among the treatment groups. Growth was still on the rise and there was a significantly (P<0.01) strong relationship (correlation and regression) between feed intake and weight gain for all the treatment groups. was concluded that both kulikuli and TGSM are potential feed resources for rabbits, more available to house hold farmers, equally economical as GNC and better still if groundnut farmers and or processors of kulikuli raise rabbits, though TGSM had less value for growth rate compared to GNC and Kulikuli at these levels of inclusion

A total of seventy-two weaner rabbits of eight weeks of age were used to assess the effects of replacing groundnut cake (GNC) with blood vegetable waste meal (BVWM) in the diets of rabbits. The BVWM was fed to replace dietary GNC at 0, 15, 30, and 45%, with GNC being 15% in the control diet. The four experimental diets were fed ad libitum for a period of eight weeks. BVWM was analyzed to contain a crude protein value of 62.35%. There were comparable feed intake values by rabbits on all the diets although the rabbits in the higher replacement levels of BVWM tended to have consumed more of the feed. There were significant increases (P<0.05) in body weight gain by rabbits as the BVWM level increased in the diet. Similarly, the feed to gain ratio improved and nitrogen digestibility increased (P<0.05) with higher levels of BVWM in the diet. This study shows that rabbits can tolerate the 45% BVWM replacement of groundnut cake effectively.

An investigation on Long Evans male rats fed with different edible fats and oils was conducted in the Department of Physiology, Bangladesh Agricultural University, Mymensingh during a period of 7 weeks (1st April to 19th May, 2005) to determine and to compare the effect of feeds on body weight gain and on weights of some selected organs (heart, liver and kidney) removing the impact of unequal feed intake. A total of 20, six-week old male rats were randomly divided into A, B, C and D groups. Each group consisted of 5 rats. Rats were fed rat pellets purchased from ICDDR,B, Dhaka supplemented with beef fat in group A, fish fat in group B and soybean oil in group C while group D was considered as control and fed only with rat pellets. The concentration of fats and oils were 7% of normal diet and fed for 7 weeks. The highest weekly mean body weight gain (19.90g) adjusted for unequal feed intake was achieved by the rats of beef fat supplemented group A, followed by the rats of soybean oil supplemented group C (19.76g) and fish fat supplemented group B (15.67g). But none of the adjusted means of weekly body weight gain differed significantly (p > 0.05) from the control. Insignificant increases in heart weight were recorded in all treated rats and the maximum weight was in fish oil treated ones. Not much differences were recorded in the kidney weights rather beef oil treated rats' kidney had the lowest mean weight. A significantly (p < 0.01) higher liver weight was recorded in group B & C compared to control (group D), though the differences between A & D were insignificant. It could be concluded that fats and oils are harmful for the rat's body especially on liver and heart.

Abstract In the United States, bioethanol is generated from corn and biodiesel from soybean oil to reduce the dependence on fossil fuels. Ethanol production generates DDGS, high in bypass protein and soluble carbohydrates, which can be used as a cheaper alternative replacement for corn and soybean. This experiment was conducted to evaluate voluntary feed intake, body weight gain and blood metabolites of lambs fed legume-based diets supplemented with corn and soybean meal or dried distillers grain with solubles (DDGS). Animals were individually housed in pens (1.52 mx 1.52 m) under a modified carport shed with woodchips as bedding. They were stratified into four groups (n = 9) with similar weights and standard deviation and randomly assigned to four treatments. The lambs were fed ground sericea hay (SL) or alfalfa meal (ALF) with either corn and soybean meal (control) or DDGS for 60 days. Treatments were SLC, SLDDGS, ALFC and AFLDDGS. The lambs were fed ad libitum based on their selected treatment and given water daily. At the end of the 60 days, weights and blood samples were collected. Plasma samples were analyzed for blood urea nitrogen (BUN), glucose and non-esterified fatty acids (NEFA). Data were analyzed using Proc Mix Procedure of SAS. Results indicated that replacing corn with DDGS did not (P &gt; 0.05) affect voluntary feed intake, final live weight and carcass weight. Blood NEFA and glucose were not affected by dietary treatments. BUN increased in lambs fed alfalfa with corn and soybean meal compared to animals fed either legume supplemented with DDGS. Similarly animals fed sericea have lower (P &lt; 0.05) BUN (19 vs 23 mg/dL) when corn and soybean meal were replaced with DDGS. DDGS can be used in legume diets for growing lambs in replacement for corn and soybean meal.
